Baghdad soars to 125 blistering degrees, its highest temperature on record

SOURCE: Washington Post DATE: July 29, 2020 SNIP: Record high temperatures have been plaguing the Middle East, the mercury soaring to extreme levels during a blistering and unforgiving heat wave. Baghdad surged to its highest temperature ever recorded Tuesday. Tuesday’s preliminary high of 125.2 degrees (51.8 Celsius) in Iraq’s capital city shatters its previous record of 123.8 degrees set on July 30, 2015, for any day of the year. On Wednesday, Baghdad followed up with a temperature of 124 degrees, its second-highest temperature on record. On Monday, it had reached 123 degrees. The crippling heat forced many residents indoors, and street sellers had to seek whatever shade they could find. With the state electricity grid failing, many households were relying on generators to power fridges, fans or air-conditioning units, the machines adding a guttural hum to the city’s already-noisy streets. Two protesters were shot dead by security forces Monday during demonstrations over a lack of electricity and basic services amid the heat wave. In nearby Lebanon, where a nationwide electricity crisis has left much of the country with less than three hours of state-provided power per day, the cost of a generator had doubled, leaving many households to go without. [O]n Wednesday, Damascus, Syria’s capital city, tied its hottest temperature on record, hitting 114.8 degrees (46 Celsius). More near-record temperatures in the 120s are likely Thursday in and around Baghdad before a slight moderation Friday. Highs to round out the week into the weekend should fall back into the upper...
What a 100-degree day in Siberia really means

What a 100-degree day in Siberia really means

SOURCE: National Geographic DATE: June 23, 2020 SNIP: An extended heat wave that has been baking the Russian Arctic for months drove the temperature in Verkhoyansk, Russia—north of the Arctic Circle—to 100.4°F on June 20, the official first day of summer in the Northern Hemisphere. This record high temperature is a signal of a rapidly and continually warming planet, and a preview of how Arctic warming will continue in an increasingly hot future, scientists say. “For a long time, we’ve been saying we’re going to get more extremes like strong heat waves,” says Ruth Mottram, a climate scientist at the Danish Meteorological Institute. “It’s a little like the projections are coming true, and sooner than we might have thought.” Saturday’s record wasn’t just a quick spike before a return to more normal summer temperatures for the Russian Arctic: The heat wave behind it is projected to continue for at least another week. It was the hottest temperature ever recorded in the town, where records have been kept since 1885. [C]limate change is “loading the dice” toward extreme temperatures like the one recorded this week…. The Arctic is warming more than twice as fast as the rest of the planet: Baseline warmth in the high Arctic has increased by between 3.6 to 5.4°F(2 to 3°C) over the past hundred or so years. About 0.75°C of that has occurred in the last decade alone. That means any heat waves that hit the region are strengthened by the extra warming. So the average warmness of a summer increases, and the extremes do too. This month’s super-hot day emerged from a potent mix...
New marine heat wave resembles killer ‘Blob’ that devastated sea life on West Coast, NOAA says

New marine heat wave resembles killer ‘Blob’ that devastated sea life on West Coast, NOAA says

SOURCE: Seattle Times DATE: September 5, 2019 SNIP: A new marine heat wave has formed off the West Coast that is similar to “The Blob” that devastated sea life and ravaged runs of Pacific salmon. Although the similarities are striking, whether the new system will cause the same havoc is yet to be seen. Like The Blob, which formed in 2014 and peaked in 2015, the new mass of warm water emerged over the course of a few months. A persistent weather pattern has becalmed winds that typically stir up the ocean’s surface to keep it cool. The heat wave is relatively new and right now mostly has affected the upper layers of the ocean. If weather patterns shift, it could break up rapidly, according to the National Oceanic and Atmospheric Administration (NOAA). “It looks bad, but it could also go away pretty quickly,” said Nate Mantua, a research scientist at NOAA’s Southwest Fisheries Science Center in La Jolla, California, in a news release Thursday. The Blob upended the West Coast marine ecosystem, resulting in the deaths of millions of animals, from seabirds to sea lions. Salmon runs cratered, adding to the stress on animals that eat them, including endangered southern resident killer whales. The new expanse of unusually warm water is eerily similar: It has quickly grown in much the same way, in the same area, to almost the same size, stretching from roughly Alaska to California. It is the second-largest marine heat wave in terms of area in the northern Pacific Ocean in the last 40 years, after the earlier Blob. About five years ago, sea temperatures...
Europe Is Warming Faster Than Even Climate Models Projected

Europe Is Warming Faster Than Even Climate Models Projected

SOURCE: Yale Environment 360 DATE: August 28, 2019 SNIP: Climate change is raising temperatures in Europe even faster than climate models projected, according to new research published in the journal Geophysical Research Letters. The number of summer days with extreme heat in Europe has tripled since the 1950s, while the number of days with extreme cold more than halved. Extremely hot days in Europe have become hotter by an average of 4.14 degrees Fahrenheit, the study found, while extremely cold days have warmed by 5.4 degrees F. The research examined data from weather stations across Europe from 1950 to 2018, with more than 90 percent of stations showing that the climate was warming. “Even at this regional scale over Europe, we can see that these trends are much larger than what we would expect from natural variability,” Ruth Lorenz, a climate scientist at the Swiss Federal Institute of Technology in Zurich and lead author of the new study, said in a statement. “That’s really a signal from climate change.” The research comes after an extremely hot summer in Europe. Southern France hit 114.8 degrees F — a new record — in late June. Germany, the Netherlands, and Belgium also recorded all-time national temperature highs. The U.S. National Oceanic and Atmospheric Administration recently announced that July was the hottest month ever recorded on Earth. “In the Netherlands, Belgium, France, the model trends are about two times lower than the observed trends,” said Geert Jan van Oldenborgh, a climate analyst at the Royal Netherlands Meteorological Institute in De Bilt, Netherlands, who was not connected to the new study. “We’re reaching new...
China is going to get hot

China is going to get hot

SOURCE: Cosmos DATE: August 7, 2019 SNIP: Two months ago, climate scientists studying US cities found that global warming could produce killer heat waves causing thousands of excess deaths during unusually hot summers like the one now affecting the eastern US and much of Europe. Now, researchers have found that China faces an even worse problem – not just a few thousand extra deaths in unusually hot summers, but tens of thousands of additional deaths each year. And the problem, they say, will kick in at much lower rates of global warming than those predicted to endanger US cities. Part of the problem, write Yanjun Wang of Nanjing University of Information Science & Technology and colleagues, in the journal Nature Communications, is that temperatures in China have been increasing faster than the global average. But it isn’t the rise in average temperature that is the true problem, Wang’s team writes, so much as the fact that this rise is accompanied by an increase in the number of dangerously hot days. In Chinese cities, they say, global warming of 1.5° degrees Celsius from pre-industrial levels (the Paris Agreement’s most ambitious not-to-exceed goal) could produce a 32.6% increase in the number of dangerously hot days. An increase of 2.0 degrees (the Paris Agreement’s less-ambitious back-up goal) could produce a 45.8% increase. Combining that with heat-fatality data from 27 large Chinese cities, the researchers calculated heat-death rates per year under each warming scenario, then extrapolated them to the rest of China’s 831 million city dwellers. Their conclusion was that the difference between 1.5° degrees and 2.0° degrees matters – a lot. Even...
