Record-breaking Heatwave shifts east as Millions of Americans under Heat Alert.

Record-breaking heatwave shifts east as millions of Americans under heat alert. Over 245 million Americans are expected to experience 90F temperatures early this week, with some as high as 105F Guardian Michael Salinato   Sun 14 Jul 2024  heatwave that impacted the US west coast over the past week is now moving east into the midwest and south-east, as millions of Americans have been under a heat alert at some point in the past week.

“Numerous near record-tying/breaking high temperatures are possible over the central High Plains and Southeast Sunday, and along much of the East Coast by Monday,” reported the National Weather Service.Cities on the east coast such as Baltimore and Washington DC will experience temperatures up to 100F (38C) this Tuesday. Temperatures in the west are expected to fall to typical summer averages.New York City is expected to experience temperatures as high as the mid-90s on Tuesday, with a forecasted heat index between 95-100F (35-38C) from Monday to Wednesday. while some areas around the city could expect a heat index of up to 105F (40C).  p in mind that the elderly, small children, people on medication, or with weight or alcohol problems are most susceptible to heat related stresses,” cautioned the National Weather Service ahead of the heatwave shifting to the east. “This is especially true during a heatwave in areas where a more moderate climate prevails, such as Wisconsin. It’s a good idea to periodically check in with those most susceptible to the heat and help them obtain relief from the extreme heat and humidity.” June 2024 was the hottest month of June on record and the 13th consecutive hottest month on record, with 14.5% of the world’s surface reporting record heat, beating June 2023 by 7.4%. Keep in mind  the US have been reported so far in July 2024, which is likely an underestimate due to the time it takes for investigations into deaths to be completed.   

How worried should we be about the climate? We asked every expert we could Every day we interviewed the world’s leading climate scientists about the state of the world. These experts are increasingly alarmed, terrified about the future and furious their warnings continue to be ignored.For a one-of-a-kind reporting project, we set about trying  to measure just how worried they are. Environment editor Damian Carrington contacted 843 senior authors of recent reports by the Intergovernmental Panel on Climate Change, the UN’s expert body. The high number of responses we received – 380 – reflected the strength of their alarm. Close to half of the scientists  anticipate at least 3C of global heating, a cataclysmic prospect.        https://www.theguardian.com/environment/article/2024/jul/14/us-heat-wave-moves-east

Extended and severe heat waves that continue to grip 50% of northwest India have claimed at least 110 lives and caused 40,000 to suffer from suspected heatstroke, the Hindustan Times reported. Delhi recorded its highest ever minimum temperature in a 55- year record this week, when night-time temperatures did not drop below 35.2C, the Hindu reported. Reuters reported that a senior government official said “Indian cities have become heat traps” due to unbalanced urban growth reducing water availability.

EAST ASIA: Meanwhile, state-run newspaper China Daily reported that the nation is “experiencing more frequent and intense heatwaves due to global warming”, according to China’s National Climate Centre. It added that the average heatwave starting date has advanced by 2.5 days per decade. The Hong Kong-based South China Morning Post reported that extreme weather has continued in China this week, including deadly torrential rain and drought conditions.

DEADLY PILGRIMAGE: In the Middle East, more than 1,000 hajj pilgrims have reportedly died amid scorching heat in the holy city of Mecca in Saudi Arabia, Sky News reported. Agence France-Presse said that temperatures reached 51.8C in Mecca as around 1.8 million people took part in the “days-long, mostly outdoor” pilgrimage. It added that the death toll is expected to rise further as many continue to search for family members.

US FURNACE: Tens of millions of people in the US were under dangerous heat warnings this week as some cities faced record-breaking temperatures, the Associated Press reported. The Guardian reported that about 80% of the country’s population are experiencing “a kind of heatwave not seen in decades”, which brought prolonged periods of temperatures above 32.2C, “under a weather phenomenon known as a heat dome”.

‘BRUTAL’ EUROPE: After registering Europe’s highest recorded temperature of 48.8C in 2021, Sicily is again having to turn away tourists as “brutal heatwaves” have led to crops dying and farm animals facing slaughter, reported the Times. Elsewhere in Europe, a wildfire near Athens, Greece forced dozens to flee their homes, reported Reuters. Officials said the fire was the result of arson and spread quickly in hot, dry conditions, the newswire added.

Florida Summary......From 1980–2024 (as of June 10, 2024), there have been 89 confirmed weather/climate disaster events with losses exceeding $1 billion each to affect Florida. These events included 7 drought events, 4 flooding events, 5 freeze events, 32 severe storm events, 32 tropical cyclone events, 4 wildfire events, and 5 winter storm events. The 1980–2023 annual average is 1.9 events (CPI-adjusted); the annual average for the most recent 5 years (2019–2023) is 4.8 events (CPI-adjusted).    https://www.ncei.noaa.gov/access/billions/state-summary/FL  

Heat Waves Everywhere 0n the Planet in May 2924

 India’s deadly heat kills over 200 people, including dozens of poll workers as elections wrap up. One state reported 45 deaths in a single day as heatwaves continue. The Independant  Stuti Mishra- Asia Climate Correspondent 03 June 2024 Over 200 people, including dozens of workers on election duty, have died in the last few days in India as the country continued to reel from the cascading impacts of heatwaves. At least 50 deaths have been reported in just the last 72 hours with the total tally for heatstroke-related deaths now standing at 211. Out of these 50, at least 33 were workers stationed on election duty who died on Saturday when India was conducting the seventh and last phase of its mammoth six week long elections. Most of these people were working as home guards, sanitation workers, and other poll staff. Election duty is compulsory in India for public sector employees. Election duty is compulsory in India for public sector employees. They’re assigned by the election commission before polling begins. A voter also died at a polling booth in the Sikandarpur area of Ballia city during the polling. The election commission of India has been criticised for not taking the heatwave warnings in consideration while planning the national elections with close to a billion eligible voters. Voters have been coming out in searing heat without any preparations made to protect them. In earlier phases, voters have complained of discomfort and local media reported several people fainting in heat. India’s heatwave has been brutal this year, with temperatures close to 50 degrees Celsius in Delhi, prompting a water and electricity crisis. Dozens of heatwave related deaths have been reported in recent days from different states. The eastern state of Odisha was the hardest hit and reported 45 deaths in a single day Heatwave days across India have increased by 125 per cent in May, a record jump compared to normal, impacting a billion people, the India Meteorological Department (IMD) said. “This could be the worst summer in the last 120 years, at least for north India,” Vimal Mishra, professor of Earth Sciences at IIT Gandhinagar, told news agency PTI.,,,,,read on.....https://www.independent.co.uk/climate-change/news/india-heatwaves-deaths-election-2024-b2555692.html?lid=a3rblbxvo1o6&utm_medium=email&utm_source=braze&utm_campaign=Climate%20Newsletter%2004-06-24&utm_term=IND_Climate_Newsletter       

And it's Happening Golabally..........The May global surface temperature was 1.18°C (2.12°F) above the 20th-century average of 14.8°C (58.6°F), making it the warmest May on record. This was 0.18°C (0.32°F) above the previous record from May 2020. May 2024 marked the 48th consecutive May (since 1977) with temperatures at least nominally above the 20th-century average. May had a record-high monthly global ocean surface temperature for the 14th consecutive month. El Niño conditions that emerged in June 2023 were replaced by ENSO-neutral conditions during the past month, and according to NOAA's Climate Prediction Center La Niña is favored to develop during July-September (65% chance) and persist into the Northern Hemisphere winter 2024-25 (85% chance during November-January). The Northern Hemisphere also ranked as the warmest May on record at 1.44°C (2.59°F) above average. The Northern Hemisphere land temperature was also record warm in May (tied with 2020) and the ocean temperature was again record-high by a wide margin (0.25°C/0.45°F warmer than the previous record set in 2020). The Arctic region had its 11th warmest May on record. May 2024 in the Southern Hemisphere also ranked warmest on record at 0.92°C (1.66°F) above average. The ocean-only temperature for May in the Southern Hemisphere ranked highest on record, while the land-only Southern Hemisphere temperature was 6th warmest on record. Meanwhile, the Antarctic region had its 23rd warmest May, 0.55°C (0.99°F) above average.

A Heatwave of Truly Monstrous Proportion across Asia

Bill McKibbon- Nearly 70 percent of the planet’s landmass, and nearly 90 percent of its population, is in the northern hemisphere. That means that the next six or eight weeks encompass the hottest days on planet earth each year, as we straddle the summer solstice on this side of the equator—the hottest days usually follow the solstice by a week or three, as the heat accumulates from all that sunlight on land and sea. Last year, in early July, we had the string of what researchers are certain were the hottest days the earth had seen in the last 125,000 years. Since then we’ve had twelve straight months of all-time records; we learned earlier today that May joined that list.

So while climate disaster can and does come in all seasons and all places now, we are heading into the peak of what you might call greenhouse season, when one can be sadly certain of hideous news. Right now we are seeing a heatwave of truly monstrous proportion across Asia—the temperature in New Delhi these past days has topped120 degrees Fahrenheit for the first time in its recorded history. (And the British colonizers were at least good about recording temperatures). This newsletter doesn’t describe every hideous consequence of global warming, because there’s not much we can do about it—our job is to try and keep it from getting worse. But sometimes moral and intellectual clarity demands simple description.Heat like this kills people, obviously—and when eventually total mortality statistics are analyzed, it will turn out that it killed many many more than we now know, people whose hearts simply gave out. But most people won’t die—there are 35 million people in Delhi, and most will live to endure the almost unimaginable, day after day.

I’ve spent a fair amount of time there over the years—it’s a leafy city, and home to some of the world’s most moving monuments, above all the Raj Ghat, where Gandhi was cremated. But it’s also badly polluted, filled with the smoke from cars and auto-rickshaws, cooking fires and factories; the last time I was there you couldn’t see the giant Indian flag at Connaught Place from across the street. And now—now it’s very like hell. It’s hard enough if you’re rich. Nitin Singh, a lawyer, told his story to the Guardian: “My home has three air conditioners, but frequent power outages have left me helpless,” said Singh. “A two-hour power outage last night compelled me to reserve a hotel room for my sick father and kids. My wife and I spent the majority of the night on our home’s terrace, and we had trouble falling asleep even for a few hours.” But most Delhiites are very very poor. Many of the city’s slums have no running water, and as supplies have dwindled in the heat, the trucks that deliver water for a price have dwindled. Here’s Esha Mitra of CNN, describing the arrival of the water wagon in one neighborhood: Dozens of people run to the truck, some even climbing on top of it to throw pipes in, pushing in to get their containers filled with water. It’s first come first served, and many people miss out. Mother-of-six Poonam Shah is one of those people. “There are 10 people in my family – six kids, me and my husband, my in-laws, relatives come over sometimes – can we all bathe in one bucket of water?” she asks. Today her family may not even have one bucket. Poonam was working her street food stall when the water truck arrived. She tried to run back for it – but it was too late, the water had run out. It’s not just Delhi, of course. As the Times reported last week, “over the past year of record-shattering warmth, the average person on Earth experienced 26 more days of abnormally high temperatures than they otherwise would have.” 

Right now Mexico is sweltering under record heat—monkeys by the hundreds are falling dead from trees, and people in the nation’s capital are forming human chains to block streets so that the government will send them water trucks. As Axios reports, the largest city in North America—which has already seen record temperatures and huge drifts of hail—could run out of water in the next few days.....read on https://open.substack.com/pub/billmckibben/p/intensity?r=mwxsy&utm_campaign=post&utm_medium=email

How Air Pollution Has Put a Brake on Global Warming. In an interview with Yale Environment 360, Norwegian climate scientist Bjørn H. Samset

IS PLAYING WITH MOTHER NATURE, A GOOD IDEA? How Air Pollution Has Put a Brake on Global Warming. In an interview with Yale Environment 360, Norwegian climate scientist Bjørn H. Samset talks about the results of his team’s recent research showing that aerosols linked to human activities cool the planet far more than previously  . YALEe360 RICHARD SCHIFFMAN • MARCH 8, 2018 Pollution particles emitted by diesel cars and trucks, coal-fired power plants, factories, rudimentary cook stoves, and the burning of forests are major contributors to the unhealthy pall of smog that blankets many cities and regions, particularly in the developing world. Scientists have long known that these aerosols serve to block incoming solar radiation and temporarily cool the planet, but now an international team of scientists has quantified that cooling effect, saying the earth would be 0.5 to 1.1 degree C (0.9 to 2 degrees F) warmer if that pollution were to suddenly disappear.

In an interview with Yale Environment 360, lead author Bjørn H. Samset of Norway’s Center for International Climate Research discusses the implications of this research. As countries like China make progress in reducing air pollution, regional planners should be prepared for the cleaner air to cause a jump in temperatures even above those expected under global warming scenarios. At the same time, Samset says, rising temperatures will likely lead to an increase in precipitation as more water evaporates from oceans, lakes, and rivers. 

In Samset’s view, the recent findings should not be taken as a green light to ramp up controversial geoengineering efforts to spray aerosols into the atmosphere, a prospect he likens to Russian roulette. “In Russian roulette, you know there’s a bullet in there,” Samset told Yale 360. In the case of geoengineering, “there might not be a bullet, you might be lucky. But would you count on it? The precautionary principle argues against it.” Yale Environment 360: With these aerosols, is particle size important? Bjørn Samset: Yes, it is. The thing that connects all aerosols is that they are all of a size that is relevant for interaction with sunlight. The reactions with sunlight — the scattering of sunlight which leads to a cooling effect — become stronger as the aerosols grow, at least up to a certain size. For the sulfate aerosols, for instance, they tend to grow in humid air as water molecules and droplets tack onto them. The longer they are in the atmosphere, the stronger their effect becomes. There is a time element with aerosols after they are emitted, and that is where some of the detailed science is going at the moment — into tracking the evolution of these particles in the air over time. e360: How does the presence of these particles impact climate? Samset: They act as mirrors or as miniature clouds, and they reflect the sunlight back into space. So if the earth was surrounded with these aerosols, a lot of the sunlight would reflect back out and you would get cooling. That is exactly what we see. We believe that the volume of human-created aerosols is so great that they have counteracted the effect of global warming to a certain extent. There is a kind of tug of war taking place between the warming greenhouse gases and the mainly cooling aerosols. e360: That is ironic — pollution is actually slowing down global warming. Samset: Yes, it turns out we have actually been helping ourselves — we’ve been polluting ourselves toward a slightly cooler climate, we’ve been mitigating climate change through pollution.   https://e360.yale.edu/features/air-pollutions-upside-a-brake-on-global-warming#:~:text=So%20if%20the%20earth%20was,warming%20to%20a%20certain%20extent.
