Scientists Identify the Most Extreme Heatwaves Ever Recorded Globally
MAY 4, 2022

https://www.eurekalert.org/news-releases/951507

Introduction:
(EurekAlert) A new study has revealed the most intense heatwaves ever across the world – and remarkably some of these went almost unnoticed decades ago.

The research, led by the University of Bristol, also shows heatwaves are projected to get hotter in future as climate change worsens.

The western North America heatwave last summer was record-breaking with an all-time Canadian high of 49.6 °C in Lytton, British Columbia, on June 29, an increase of 4.6 °C from the previous peak.

The new findings, published today in Science Advances, uncovered five other heatwaves around the world which were even more severe, but went largely underreported.

Lead author, climate scientist Dr Vikki Thompson at the University of Bristol, said: “The recent heatwave in Canada and the United States shocked the world. Yet we show there have been some even greater extremes in the last few decades. Using climate models, we also find extreme heat events are likely to increase in magnitude over the coming century – at the same rate as the local average temperature.”

Here in Oregon we're having the wettest and coldest spring I've ever seen in my entire life. April seen record rain throughout the area... :twisted: The forecast calls for rain for the rest of the week and lower 50's.

Delhi suffers at 49C as heatwave sweeps India

By Sharanya Hrishikesh & Meryl Sebastian
BBC News, Delhi

4 hours ago

An intense heatwave is sweeping through northern India with temperatures hitting a record 49.2C (120.5F) in parts of the capital, Delhi.

This is the fifth heatwave in the capital since March.

Officials in many parts of the country have asked people to take precautions as temperatures are set to remain high.

They warned the heat could cause health concerns for the vulnerable, including infants, the elderly and people with chronic diseases.

The states of Himachal Pradesh, Haryana, Uttarakhand, Punjab, and Bihar have particularly witnessed soaring temperatures in the past few days, India's weather department said.

At least 1 killed, 23 hurt in rare northern Michigan tornado
Source: AP

By JOHN FLESHER and ED WHITE
GAYLORD, Mich. (AP) — A tornado tore through a small northern Michigan community on Friday, killing at least one person and injuring at least 23 others as it flipped vehicles, tore the roofs off of buildings, and downed trees and power lines.

The twister hit Gaylord, a city of about 4,200 people roughly 230 miles (370 kilometers) northwest of Detroit, at around 3:45 p.m.

Mike Klepadlo, owner of Alter-Start North, a car repair shop, said he and his workers took cover in a bathroom.

“I’m lucky I’m alive. It blew the back off the building,” he said. “Twenty feet (6 meters) of the back wall is gone. The whole roof is missing. At least half the building is still here. It’s bad.”

Millions Stranded as Flooding Causes Havoc in Bangladesh, India
May 21, 2022

Introduction:
(Al Jazeera) Heavy rains have caused widespread flooding in parts of Bangladesh and India, leaving millions stranded and at least 57 dead, officials have said.

In Bangladesh, about two million people have been marooned by the worst floods in the country’s northeast for nearly two decades while nearly one million people have been affected by the flooding.

At least 100 villages at Zakiganj were inundated after floodwater rushing from India’s northeast breached a major embankment on the Barak River, said Mosharraf Hossain, the chief government administrator of the Sylhet region.

“Some two million people have been stranded by floods so far,” he told AFP, adding that at least 10 people have been killed this week.

Many parts of Bangladesh and neighbouring regions in India are prone to flooding, and experts have said that climate change is increasing the likelihood of extreme weather events around the world.

No Easy Answers for U.S. Tornado Trends
by Cameron Langford
May 21, 2022

Extract:
(Courthouse News) Scientists don’t yet fully understand how tornadoes form, let alone how climate change is affecting them.

Harold Brooks, a senior research scientist at NOAA’s National Severe Storms Laboratory in Norman, Oklahoma…believes the changing patterns of U.S. tornadoes—more days with clusters of them but less days when any form—implies the structure of the jet stream has changed in ways that affect their development. But pinpointing how changes in air currents impact weather phenomenon that are very small in comparison has proven difficult, Brooks concedes.

“What we know about the structure of the jet stream is on spatial scales of a few thousand kilometers and time scales of a day or two. And when we’re trying to go from that down to something that’s a kilometer and minutes, there’s a huge mismatch in the scale,” he said.

As for climate change, experts say it is causing offsetting precursors. While it is increasing the prevalence of balmy, moist air from the Gulf of Mexico that seeds thunderstorms, it is decreasing the wind shear that spins them.

Vast differences in the temperature of air blowing down from the North Pole and up from the equator create winds that increase with height. But as climate change causes the poles to warm more than the equator, those winds diminish, which is less favorable for tornadoes.

Heat wave breaks records as more than 70 million under warnings

Updated 11 hours ago - Energy & Environment

More than 70 million are under heat warnings and advisories on Saturday through early next week as a potent heat dome sends temperatures soaring to levels the National Weather Service is calling "potentially deadly."

The big picture: The heat wave, made worse by a long-term, climate change-influenced drought, shows signs of eventually swelling into the middle of the country and then eastward through next week.

Why it matters: Extreme heat is the deadliest weather-related hazard in the U.S. each year, and climate change is making these events more likely, severe and long-lasting.
  • The public health threat of this particular heat wave is especially elevated because of the high overnight minimum temperatures, which in many locations are breaking records. For example, at 1 a.m. local time Saturday morning, Phoenix was still at 100°F.
  • "Extreme and deadly heat will continue through this weekend," the NWS forecast office in Phoenix stated, noting the "minimal overnight recovery." Forecasters noted that Phoenix may see its earliest-ever 90°F overnight low temperature.
