Here is an article I came across this morning. 49.9C is nearly 123F!

Roads melt as temperature hits 49.9C in remote SA ahead of catastrophic fire conditions

Catastrophic fire conditions have been forecast in South Australia today as the state's stifling heatwave continues into a fourth day — with temperatures hitting almost 50 degrees Celsius in some areas yesterday.

The Bureau of Meteorology (BOM) said December temperature records had tumbled in more than a dozen locations, while some towns set all-time highs.

Parts of Adelaide sweltered through the hottest night on record, with the minimum reaching just 33.6C at 10:20pm at BOM's West Terrace site.

It was the highest minimum at the site since January 1939, when it reached 33.2C.

Senior forecaster Simon Timcke said it was a preliminary record, as the temperature could still drop, but that was very unlikely.

He said the city had a hotter night at the Kent Town site in 2009, when it only dropped to 33.9C.

The minimum at Kent Town last night 33.6C at 11:30pm.

Nullarbor was the hottest spot around the state yesterday, reaching an incredible 49.9C — the fourth hottest temperature ever recorded in Australia, overtaking Eucla in WA which reached that mark just hours earlier.

Adelaide reached 45.3C on Thursday, its highest top temperature for the month of December since records began in 1887, and is forecast to reach 46C today.

Parts of the northern suburbs also hovered around 46C.

Ceduna's top of 48.8C was a record high, while Wudinna and Port Augusta — where roads melted in the intense heat — rose above 48C.

"McConnal Road, Alma Street, Forster Street and Cobbin Street have all shown signs of bleeding," Port Augusta City Council said in a statement.

"A contractor has been engaged to spread rocks over problem areas.

"The roads should be avoided and only used by local residents — please take an alternate route during this extreme weather."

SA Power Networks spokesman Paul Roberts warned there was a "heightened risk of extended power outages" in today's conditions.

"We have enacted detailed resource plans with multiple crews … and others on stand-by if needed," he said.

"Where conditions are confirmed to be catastrophic and there's evidence to suggest it would be wise and would help protect lives and property, we would disconnect [power to high bushfire risk areas]."

Catastrophic fire conditions in six districts

The heatwave conditions will take a dangerous turn today with extreme temperatures and high winds combining to produce catastrophic bushfire conditions in six districts.

Lower Eyre Peninsula, Yorke Peninsula, the Mid North, Mount Lofty Ranges, Kangaroo Island and Lower South East districts have all been given the highest fire danger rating.

Country Fire Service (CFS)deputy chief officer Andrew Stark said if fires break out today, they will be dangerous, fast-moving and erratic.

"They are the kind of conditions that are very dangerous even for our firefighters, from CFS, from MFS, Department of Environment and Water, the kind of conditions that we see property lost and unfortunately sometimes, lives lost," he said.

"Under these conditions [fires are] so erratic, they'll move so fast and develop so quickly, it doesn't matter how many firefighters we have, we're not going to stop the progress of the full spread of fires under these conditions."

Mr Stark labelled today's conditions "the most dangerous … we've faced this season", and said residents in affected areas should activate their bushfire plans, if their plan is to leave.

"The safest place is to be away from areas that will see these conditions forecast, so if your plan is not to stay, you need to think about where you will go with your family," he said.

"We have a high potential for fires to break out with the effects of lightning, which will be widespread again right across South Australia.

"We will see a very gusty wind change, and even though people may start to see some relief from those winds, if we have fires burning, they will continue to be very dangerous fires for many hours after the change goes through."

Bureau of Meteorology forecaster Kylie Egan said strong winds and the risk of lightning would elevate fire danger across the state.

"We haven't really seen conditions much worse than this across the state, the wind speeds are really as strong as they can get," she said.

"The risk of lightning is certainly there, which makes it a very significant fire weather day for South Australia."

Adelaide's temperature is expected to peak in the afternoon at 46C before the cool change moves through.

Friday's twilight horse races cancelled

On Thursday afternoon, Thoroughbred Racing SA (TRSA) announced it had cancelled its Friday twilight meet at Morphettville Racecourse, despite earlier in the week saying it would still go ahead.

The organisation's chief executive officer, Jim Watters, said while TRSA had been in contact with the BOM about the forecast for Friday evening, the latest temperature predictions were higher than expected.

"While a cool change was and continues to be forecast to arrive in time for Friday's twilight race meeting, the most recent updates indicate a higher temperature than originally advised immediately prior to the cool change," he said.

"In light of this we have determined that Friday's twilight race meeting at Morphettville will be postponed, with the meeting re-scheduled to next Monday.

"As always, the welfare of our horses and participants is our number one consideration when making these decisions, and from the outset we had advised that we would monitor the situation throughout and if deemed necessary the meeting would be postponed."

The back-flip follows condemnation from animal welfare groups about TRSA's previous plan to go ahead with the meet despite the heatwave.

The Last Decade Was The Hottest On Record Thanks To Global Warming

The Last Decade Was The Hottest On Record Thanks To Global Warming
"We are experiencing the impacts of global warming unfolding literally in real time."


NASA / Via data.giss.nasa.gov

NASA temperature map for December 2019 compared to the 1951–1980 timeframe.

Posted on January 15, 2020, at 11:40 a.m. ET

Last year was the world's second-warmest year, capping off the hottest decade on record, according to experts at NOAA and NASA.

And here’s another record to add to the pile: The past five years were collectively the warmest since record-keeping began about 140 years ago. 2019's temperatures were second only to 2016, coming in around 1.7 degrees Fahrenheit above the 20th-century average, per NOAA.

“The decade that just ended is clearly the warmest decade on record,” NASA's Gavin Schmidt said in a statement. “Every decade since the 1960s clearly has been warmer than the one before.”

This warming trend, scientists say, is undoubtedly the result of human-made climate change.

“We are experiencing the impacts of global warming unfolding literally in real time,” said Noah Diffenbaugh, an earth science professor at Stanford University not involved in the newly released analyses. “We now have clear evidence that people and ecosystems are being impacted across the world, from the equator to the poles, from both in the ocean and on land, from the coastal areas to the high elevations.”

The twin government analyses, released Wednesday, come on the heels of a new study in the journal Advances in Atmospheric Sciences concluding that the world’s oceans in 2019 were the warmest since record-keeping began around the 1950s, capping off an exceptionally warm 10-year streak for the oceans.

Meanwhile, Australia continues to struggle with unprecedented bushfires that have destroyed thousands of homes, shrouded large swaths of the country in unhealthy smoke levels, and killed more than a dozen people and thousands and thousands of animals.

“We know that the climatic conditions that enable dangerous fires are increasing globally,” Colin Beale, a biology professor at the University of York who has studied climate and fire impacts, told BuzzFeed News in an email. “We also know that the current fire season is exceptional (a product primarily of the Indian Ocean Dipole, a weather phenomenon that has now ended, probably exacerbated by underlying climate change) and is unlikely to be repeated again very soon — but could become normal if climate change is not tackled adequately.”

Climate crisis: alarm at record-breaking heatwave in Siberia

Unusually high temperatures in region linked to wildfires, oil spill and moth swarms

Published on Wed 17 Jun 2020 11.49 EDT

A prolonged heatwave in Siberia is “undoubtedly alarming”, climate scientists have said. The freak temperatures have been linked to wildfires, a huge oil spill and a plague of tree-eating moths.

On a global scale, the Siberian heat is helping push the world towards its hottest year on record in 2020, despite a temporary dip in carbon emissions owing to the coronavirus pandemic.

Temperatures in the polar regions are rising fastest because ocean currents carry heat towards the poles and reflective ice and snow is melting away.

Russian towns in the Arctic circle have recorded extraordinary temperatures, with Nizhnyaya Pesha hitting 30C on 9 June and Khatanga, which usually has daytime temperatures of around 0C at this time of year, hitting 25C on 22 May. The previous record was 12C.

In May, surface temperatures in parts of Siberia were up to 10C above average, according to the EU’s Copernicus Climate Change Service (C3S). Martin Stendel, of the Danish Meteorological Institute, said the abnormal May temperatures seen in north-west Siberia would be likely to happen just once in 100,000 years without human-caused global heating.

Freja Vamborg, a senior scientist at C3S, said: “It is undoubtedly an alarming sign, but not only May was unusually warm in Siberia. The whole of winter and spring had repeated periods of higher-than-average surface air temperatures.

“Although the planet as a whole is warming, this isn’t happening evenly. Western Siberia stands out as a region that shows more of a warming trend with higher variations in temperature. So to some extent large temperature anomalies are not unexpected. However, what is unusual is how long the warmer-than-average anomalies have persisted for.”

Marina Makarova, the chief meteorologist at Russia’s Rosgidromet weather service, said: “This winter was the hottest in Siberia since records began 130 years ago. Average temperatures were up to 6C higher than the seasonal norms.”

Robert Rohde, the lead scientist at the Berkeley Earth project, said Russia as a whole had experienced record high temperatures in 2020, with the average from January to May 5.3C above the 1951-1980 average. “[This is a] new record by a massive 1.9C,” he said.

In December, Russia’s president, Vladimir Putin, commented on the unusual heat: “Some of our cities were built north of the Arctic Circle, on the permafrost. If it begins to thaw, you can imagine what consequences it would have. It’s very serious.”

Thawing permafrost was at least partly to blame for a spill of diesel fuel in Siberia this month that led Putin to declare a state of emergency. The supports of the storage tank suddenly sank, according to its operators; green groups said ageing and poorly maintained infrastructure was also to blame.

Wildfires have raged across hundreds of thousands of hectares of Siberia’s forests. Farmers often light fires in the spring to clear vegetation, and a combination of high temperatures and strong winds has caused some fires to burn out of control.

Swarms of the Siberian silk moth, whose larvae eat at conifer trees, have grown rapidly in the rising temperatures. “In all my long career, I’ve never seen moths so huge and growing so quickly,” Vladimir Soldatov, a moth expert, told AFP.

He warned of “tragic consequences” for forests, with the larvae stripping trees of their needles and making them more susceptible to fires.
We’ve never had a better chance …

… to make a greener world. Covid-19 has delivered unusual environmental benefits: cleaner air, lower carbon emissions, a respite for wildlife. Now the big question is whether we can capitalise on this moment. The Guardian aims to lead the debate from the front.

As an open, independent news organisation we investigate, interrogate and expose the actions of those in power, without fear. Our independence gives us the freedom to make important organisational choices in service of the environment: we have committed to carbon neutrality by 2030, divested from the oil and gas sectors – and renounced fossil fuel advertising. With your help we can bring about improvement.

The Guardian believes that the climate crisis we face is systemic. We will inform our readers about threats to the environment based on scientific facts, not driven by commercial or political interests. We will keep reporting on the efforts of individuals and communities around the world who are fearlessly taking a stand for future generations and the preservation of human life on earth. We want their stories to inspire hope.

Millions are flocking to the Guardian for quality news every day. We believe everyone deserves access to information that is fact-checked, and analysis that has authority and integrity. That’s why, unlike many others, we made a choice: to keep Guardian reporting open for all, regardless of where they live or what they can afford to pay.

A sustained blast of heat is expected to bake much of the United States with hotter-than-usual temperatures this holiday weekend, and forecasts suggest that the heat and the humidity could linger for several weeks.

The extreme weather — the first major heat wave of the season — comes as many states are scrambling to contain the rampant spread of the coronavirus and resources are already strained. And while the pandemic presents some unique challenges this summer, experts say these extreme events will continue to pose public health risks because climate change is making heat waves around the world more frequent and more intense.

The coming heat is projected to affect huge parts of the U.S., from eastern New Mexico and Colorado across the central Plains and into the Northeast.

"The first half of July looks to have well-above-normal temperatures, at pretty high probabilities, beginning around the Fourth of July or slightly before," said Jon Gottschalck, chief of the Operational Prediction Branch at the National Weather Service's Climate Prediction Center.

Some places are already sweltering under record conditions. Miami recently had its hottest week on record and posted its 11th consecutive day with a heat index over 103 degrees, Brian McNoldy, a senior research associate at the University of Miami's Rosenstiel School of Marine and Atmospheric Science, tweeted Thursday.

Gottschalck said it's likely that several regions may be under heat advisories and excessive heat watches, and he said warm conditions may persist into the evenings, with little relief from the humidity.

The heat is being driven by the northward shift of the jet stream, which creates a "ridging effect" — a pocket of high pressure that allows for warm, dry conditions at the surface, Gottschalck said. The impending blast of heat could also create a "ring of fire" weather pattern, in which storms ride along the periphery of the heat dome and trigger severe thunderstorms across the northern Plains, he said.

Current forecasts show that this dome of heat could stick around well into the month.

"Our models indicate that this is going to be somewhat persistent through the first two weeks of July, and potentially longer," Gottschalck said.

He said the Climate Prediction Center has been working closely with the Federal Emergency Management Agency and local agencies on how to manage heat waves and other extreme weather events during the pandemic.

Some cities, for instance, may not be able to provide relief for vulnerable people because of social distancing guidelines.

"We're dealing with such a unique situation, where even if some areas can open up cooling centers and things like that, they're likely to have limited capacity," said Julie Caron, a climate scientist at the National Center for Atmospheric Research in Boulder, Colorado. "So now, you could have a vulnerable population that has to make a choice to either stay home and risk the heat or go to a cooling center and risk exposure to the virus."

Heat wave to roast Northeast as temps forecast to approach 100 F


Accuweather
Alex Sosnowski
Jul 17th 2020 2:48PM

The hottest weather of the summer is poised to swelter many areas of the mid-Atlantic, central Appalachians and southwestern and central New England late this weekend to the first part of next week.

A portion of the same weather system, a large area of high pressure, that has been building and broiling the south-central United States much of this week will poke northeastward in the coming days.


Actual temperatures are forecast to rise well into the 90s F from portions of Ohio, Pennsylvania, New York state, Vermont, Connecticut, Rhode Island, New Hampshire, Massachusetts, West Virginia, New Jersey, Maryland, Delaware and Virginia.

A few locations over the mid-Atlantic and Ohio Valley can reach or exceed 100 degrees for a couple of hours in the afternoon on Sunday and Monday.

It will be so hot across the contiguous United States that the average high temperature will be more than 90 F on Saturday, according to Ryan Maue, meteorologist and data scientist at Bamwx.com.

AccuWeather RealFeel® Temperatures will be several degrees higher than the actual temperature. The RealFeel Temperature not only takes into consideration the temperature and humidity but also sunshine, any breeze and other factors that provide a true representation of how hot the air feels on the human body.


Daily records that have stood since the 1930s and even near the turn of the 20th century will be challenged.

In Washington, D.C., and Cleveland, the records of 102 and 95, respectively, on Sunday were set in 1930. Farther north, in Albany, New York, Sunday's record of 97 was set all the way back in 1904.


In Philadelphia and Baltimore, the records on Monday of 99 and 102, respectively, were also set in 1930.

A heat wave is generally defined as a stretch of 90-degree-Fahrenheit (or higher) temperatures for at least three days in a row over the northern U.S.

The conditions may cause some cities to be dangerously hot around the clock for a several-day stretch. This phenomenon, known as the 'urban heat island effect,' comes into play as the concrete and brick buildings begin to finally cool near daybreak, just as the new day will be getting underway.

People are urged to seek air-conditioned environments where possible and to drink plenty of non-alcoholic and non-caffeinated fluids as alcohol and caffeine can accelerate the dehydration process.

Meteorologists recommend avoiding strenuous physical labor or exercise during the late morning, afternoon and early evening hours when air temperatures climb to the highest levels of the day.

A 20-day streak of temperatures hitting 90 or higher in Washington, D.C., just came to an end on Wednesday -- just one day shy of tying the longest stretch of 90-degrees days on record (set in 1980 and tied in 1988). The high was held to 87 on Thursday due to persistent cloud cover and a breeze off the slightly cooler waters of the Potomac River. The highest temperature at Reagan National Airport during the brutal stretch was 97 on July 3. A new stretch of 90-degree weather will commence on Friday.

So far, this summer's high in New York City was 96 set on July 6. Temperatures on Monday may challenge this mark.

Farther north, the heat wave which spanned June 18-23 may be tough to surpass. Temperatures reached 96 in Burlington, Vermont, but on Sunday, temperatures may not only reach that mark, but they could also challenge the record high of 98 set in 2013.

Even over the mountains in the region, the uniformly hot air mass will allow little relief, except for a cool lake, stream or pool.

How hot the weather will get in eastern New England is a bit more tricky as a sea breeze may step in to mitigate temperatures, including around Boston. Still, temperatures are forecast to approach 90 on Sunday and Monday.

The cooler of the weekend days will be Saturday at most beach locations with an active sea breeze, but on Sunday and Monday, due to a west to southwest breeze from the land, the hot air is likely to be felt on most beaches from New Jersey to Delaware, Maryland and Virginia.

The combination of a slight dip in the jet stream and a weak push of slightly cooler air may be enough to keep high temperatures in the 80s for the middle and latter parts of the week around the eastern Great Lakes, eastern Ohio Valley, central Appalachians and portions of New England.

At least spotty thunderstorm activity is forecast to accompany the slight shift in the jet stream and proximity of surface fronts. Just as a dry landscape functions more like a desert with a rapid rise in temperature during the day, a wet landscape requires more of the sun's energy being used to evaporate moisture, rather than heating the ground and adjacent air. For this reason, it is much easier for temperatures to surge when the ground is dry as opposed to when the ground is wet.

Along the mid-Atlantic coast, even though temperatures may be trimmed a few degrees later next week, highs are still likely to be at or above 90 in most cases. A slight cooling sea breeze may be more active during the middle and latter parts of the week on the beaches, as opposed to the start of the week.

Good beach weather. Still under 40 degrees C so should be fairly manageable I would have thought. (105 in your scale) Wear a hat, drink water, reduce exertion in hottest part of the day etc...
Once it starts to get into the 40's you need to take a few more additional precautions, like go to the pub and drink plenty of cold beer.

I do like a Coopers Special Stout. Of the big volume beers XXXX is good on a hot day.
No one I know drinks Fosters here in Australia. Pretty sure we just export this to the States as we feel sorry for you guys having to drink that weak camel piss you guys call beer.

The sun sets through smoke created by the Ranch Fire on Aug. 13, 2020, in Azusa, Calif. A heat wave has prompted electrical providers to issue the first rolling blackouts in the state since 2001.   Marcio Jose Sanchez/AP

California electrical providers instituted rolling blackouts Friday night – the first since 2001–as an intense and prolonged heat wave settled over much of the Western U.S.

Hundreds of thousands of people are believed to have experienced brief power outages through the evening, after the body that manages most of the state's electrical utilities declared a Stage 3 emergency to help reduce stress on the larger grid.

Electrical demand surged through the day as temperatures topped the triple digits in many parts of the state and people cranked up fans and air conditioning units to try and stay cool.

The emergency order was rescinded before midnight and power was fully restored to all affected households, the California Independent System Operator said in a tweet.

Still, demand for electricity is expected to remain high through the weekend and well into next week. The heat wave blanketing much of California and other parts of the Western U.S. is expected to persist until at least Thursday, with many places expected to reach record high maximum and minimum temperatures, according to the National Weather Service. The forecast raises questions about future electrical demand and the potential for more blackouts.

Daniel Swain, a climate scientist at UCLA, says the heat wave could be the worst in more than a decade.

Extreme heat is a silent killer, responsible for more deaths than any other natural disaster. The Centers for Disease Control and Prevention estimates that heat kills more than 600 people in the U.S. every year.

However, a recent study by researchers at Boston University and the University of British Columbia suggests the number may actually be far higher — possibly as high as 5,600 annually — with even moderate heat waves increasing the number of deaths.

Climate change is making heat waves more frequent and more intense in the Western U.S., and it's doing the same to wildfires.

Fire season is just heating up in California, with more than dozen blazes burning through the state. The heat wave won't help firefighting efforts and there are concerns it could dry out vegetation in other parts of the West, setting the stage for future fires. Fortunately, strong winds – a chief driver of California's recent deadly fires – are not forecast in the coming week. But that also means that unhealthy air and higher-than-normal humidity are likely to remain in parts of the state.

Efforts to protect people from the combination of those factors as well as blistering temperatures are being complicated by the ongoing pandemic. Health officials are urging people to stay at home and, in some parts of the country, communities have closed cooling centers to try and prevent the spread of COVID-19. That's not the case in most of California, where state and local officials have activated cooling centers to help people in need.

Many low-income families in Los Angeles lack the resources to cool their own homes, according to a recent study by researchers at the University of Southern California. In some cases, they don't have access to air conditioning. In others, they can't afford to pay for the electricity to run it.

Hundreds of thousands of Californians remain out of work because of the coronavirus pandemic, amplifying economic insecurity for families across the state.

Death Valley reaches 130 degrees, hottest temperature in U.S. in at least 107 years


By Jeff Berardelli

August 17, 2020 / 9:37 AM / CBS News

On Sunday, the thermometer at Death Valley's Furnace Creek, located in the deserts of Southern California, soared to 130 degrees Fahrenheit, according to NOAA's Weather Prediction Center. If verified, it would be the hottest temperature recorded in the U.S. since 1913, and perhaps the hottest temperature ever reliably recorded in the world.

The historic reading is just a small part of a massive, intense and long-lasting heat dome smothering the West Coast that will continue to get worse through Tuesday.

The highest temperature ever recorded on Earth was also observed in Death Valley — 134 degrees Fahrenheit in 1913. However, many experts contend that temperature reading, along with various other temperatures recorded that summer, was likely an observer error.

A 2016 analysis by Weather Underground historian Christopher Burt revealed that other observations from the region in 1913 simply do not square with the Death Valley reading.

Because of the unique landscape and meteorology, the daily readings from the various observation sites in that area of the desert Southwest are almost always in lockstep with each other. But during the week the all-time record was set in 1913, while other sites were around 8 degrees above normal, the Death Valley readings were 18 degrees above normal.

In 1931, a record-high temperature for Africa was recorded in Tunisia at 131 degrees. However, according to Burt, this recording, and many others in Africa from the colonial period, has "serious credibility issues."

Because of these discrepancies, experts say the hottest temperature ever "reliably" recorded on Earth is 129.2 degrees, from 2013 in Death Valley. That is, until now. Assuming no abnormalities are apparent, Sunday's reading will likely be accepted. It seems the reading is not suspect, but if there is reason for skepticism, the National Weather Service or World Meteorological Society may choose to conduct a review.

The current heat wave is certainly not limited to deserts. Record-breaking heat extends from Arizona to Washington state. Throughout the coming week, more than 100 temperature records are expected to be challenged. On Saturday, several cities recorded all-time high August temperatures.

The peak of the heat wave will be Monday and Tuesday, and then the dome will weaken a little as it shrinks back into the Southwest. But while temperatures may drop just a couple of degrees, the blazing heat will likely continue in California and the Southwest for the next 10 days.

Phoenix, Arizona, is right in the middle of this current heat dome, but even before that it was exceedingly hot. This summer is already the hottest on record for the desert city. By Thursday, Phoenix is expected to see its 44th day this year of at least 110 degrees. That shatters the 2011 record of 33 days.

The scorching heat is helping to ignite and spread various wildfires in the West. Hot weather dries out the air and brush, making it easier for fires to ignite and spread. Since 1972, there has been an 8-fold increase in summer forest fire extent. A recent study from Columbia University found that dry conditions in the West have also contributed to a megadrought that has been going on since 2000, making it perhaps one of the worst in 1,200 years.

Over the past few of decades, heat waves have become more intense, according to various studies. One study released earlier this summer found that, since 1950, heat waves globally are getting significantly more frequent, lasting longer and producing more cumulative heat — making populations more vulnerable to heat stress.

According to Climate Central, the western U.S. is warming the fastest of all the regions in the continental U.S. Some areas have warmed 3 to 5 degrees during summer just since 1970 due to human-caused climate change. That means heat waves start out at a higher baseline  and heat domes have more cumulative heat to concentrate, pushing heat waves into uncharted territory.

As a result, Palm Springs, California, now averages 14 extra days per summer with high temperatures of at least 110 degrees Fahrenheit.

Scientists say this heating trend will continue to become more intense as long as heat-trapping greenhouse gases continue to be released through the burning of fossil fuels. In fact, computer models project that heat index days above 100 degrees in Texas will triple from 40 days before the year 2000 to 130 days by the end of the 21st century.

LOS ANGELES (Reuters) - Californians sought relief on Friday from the first day of a punishing heat wave expected to last through the Labor Day weekend, bringing temperatures of up to 125 degrees Fahrenheit (49 Celsius) and raising the risk of wildfires and rolling blackouts.

California Governor Gavin Newsom declared a state of emergency, a proclamation that allows power plants to operate beyond normal limits throughout the three-day holiday weekend.

“The heat is on again! Please do your part to #ConserveEnergy to avoid power outages over #LaborDayWeekend. Some state beaches are closed or have modified operations due to wildfires & COVID-19,” California State Parks said on Twitter.

The National Weather Service (NWS) forecast a heat wave carrying “rare, dangerous and very possibly fatal” temperatures across Southern California for the holiday weekend.

“There is a high risk for heat illness along with heightened fire weather concerns,” the NWS Los Angeles office reported, forecasting record high temperatures on Saturday and Sunday.

State officials urged Californians to turn off unnecessary appliances and lights to help avoid blackouts from an overwhelmed power grid.

Authorities also asked power generators to delay any maintenance until after the weekend to prevent blackouts like the two nights of rolling outages in mid-August as residents cranked up their air conditioning.

This weekend was expected to be hotter than one in mid-August that helped trigger the second and third largest forest fires in California history. Those fires are still burning.

Death Valley in California’s Mojave desert registered one of the hottest air temperatures recorded on the planet of 130F on Aug. 17, and highs of around 124 were expected there on Sunday, the NWS said.

Record or excessive heat was also predicted for Nevada and western Arizona with “brutal” temperatures set to peak on Sunday and continue into Monday, the weather service said.

The NWS reported on Friday that Phoenix hit a new high for this date, registering 114 degrees at Phoenix Sky Harbor International Airport. The old record was 112 degrees set in 1945.

Red flag warnings were issued for large swaths of the state, indicating a high fire danger.

Climate scientists blame human activities for a rise in average temperatures in California since the early 20th Century and say extreme wet-dry cycles are creating parched vegetation to supercharge wildfires.

Monitoring the Arctic Heatwave: Alarmingly High Temperatures, Extreme Wildfires and a Significant Loss of Sea Ice
TOPICS:ArcticClimate ChangeEuropean Space AgencyGlobal Warming

Over the past months, the Arctic has experienced alarmingly high temperatures, extreme wildfires and a significant loss of sea ice. While hot summer weather is not uncommon in the Arctic, the region is warming at two to three times the global average – impacting nature and humanity on a global scale. Observations from space offer a unique opportunity to understand the changes occurring in this remote region.

According to the Copernicus Climate Change Service, July 2020 was the third warmest July on record for the globe, with temperatures 0.5°C above the 1981-2010 average. In addition, the Northern Hemisphere saw its hottest July since records began — surpassing the previous record set in 2019.

The Arctic has not escaped the heat. On 20 June, the Russian town of Verkhoyansk, which lies above the Arctic Circle, recorded a staggering 38°C. Extreme air temperatures were also recorded in northern Canada. On 11 August, Nunavut’s Eureka Station, located in the Canadian Arctic at 80 degrees north latitude, recorded a high of 21.9°C – which were reported as being the highest temperature ever recorded so far north.

The image above shows the land surface temperature recorded on 11 August around Eureka. This map has been generated using data from Copernicus Sentinel-3’s Sea and Land Surface Temperature Radiometer. While weather forecasts use near surface air temperatures, Sentinel-3 measures the amount of energy radiating from Earth’s surface.

Although heatwaves in the Arctic are not uncommon, the persistent higher-than-average temperatures this year have potentially devastating consequences for the rest of the world. Firstly, the high temperatures fuelled an outbreak of wildfires in the Arctic Circle. Images captured by the Copernicus Sentinel-3 mission show some of the fires in the Chukotka region, the most north-easterly region of Russia, on 23 June 2020.

Wildfire smoke releases a wide range of pollutants including carbon monoxide, nitrogen oxides and solid aerosol particles. In June alone, the Arctic wildfires were reported to have emitted the equivalent of 56 megatonnes of carbon dioxide, as well as significant amounts of carbon monoxide and particulate matter. These wildfires affect radiation, clouds and climate on a regional, and global, scale.
Siberia Wildfires

This image of Siberian fires was captured on 23 June 2020 by the OLCI instrument on board the Copernicus Sentinel-3 mission. Part of Sakha, Chukotka and the Magadan Oblast is pictured here. Sea-ice can be seen to the north while smoke dominates the bottom part of the image with a number of active fires visible in the centre.

The Arctic heatwave also contributes to the thawing of permafrost. Arctic permafrost soils contain large quantities of organic carbon and materials left over from dead plants that cannot decompose or rot, whereas permafrost layers deeper down contain soils made of minerals. The permanently frozen ground, just below the surface, covers around a quarter of the land in the northern hemisphere.

When permafrost thaws, it releases methane and carbon dioxide into the atmosphere – adding these greenhouse gases to the atmosphere. This, in turn, causes further warming, and further thawing of the permafrost – a vicious cycle.

According to the UN’s Intergovernmental Panel on Climate Change Special Report, permafrost temperatures have increased to record-high levels from the 1980s to present. Although satellite sensors cannot measure permafrost directly, a recent project by ESA’s Climate Change Initiative (CCI), combined in situ data with satellite measurements of land-surface temperature and land cover to estimate permafrost extent in the Arctic.

The thaw of permafrost is also said to have caused the collapse of the oil tank that leaked over 20,000 tonnes of oil into rivers near the city of Norilsk, Russia, in May.

The Siberian heatwave is also recognised to have contributed to accelerating the sea-ice retreat along the Arctic Russian coast. Melt onset was as much as 30 days earlier than average in the Laptev and Kara Seas, which has been linked, in part, to persistent high sea level pressure over Siberia and a record warm spring in the region. According to the Copernicus Climate Change Service, the Arctic sea ice extent for July 2020 was on a par with the previous July minimum of 2012 – at nearly 27% below the 1981-2020 average.

ESA’s Mark Drinkwater comments, “Throughout the satellite era, polar scientists pointed to the Arctic as a harbinger of more widespread global impacts of climate change. As these interconnected events of 2020 make their indelible marks in the climate record, it becomes evident that a ‘green’ low-carbon Europe is alone insufficient to combat the effects of climate change.”

Without concerted climate action, the world will continue to feel the effects of a warming Arctic. Because of the Arctic’s harsh environment and low population density, polar orbiting space systems offer unique opportunities to monitor this environment.  ESA has been monitoring the Arctic with its Earth-observing satellites for nearly three decades. Satellites not only can monitor changes in this very sensitive region, but can also facilitate navigation and communications, improve Arctic maritime security, and enable more effective management of sustainable development.

ESA’s Director for Earth Observation, Josef Aschbacher, adds, “Whilst the first generation of Copernicus Sentinels today offer excellent global data, their combined Arctic observation capabilities are limited in scope. As part of the preparation of Copernicus 2.0, three new high priority candidate missions: CIMR, CRISTAL and ROSE-L, and next-generation Sentinels are being prepared by ESA.

“Together with the Copernicus CO2M mission, these new missions will provide new pan-Arctic, year-round monitoring and CO2 emissions data to support the EU Green Deal and further boost the Copernicus climate change monitoring and service capabilities.”
