The hottest month in recorded history is going out with a bang in the United States.
Much of the eastern half of the U.S. sweltered Friday in temperatures that felt as high as 44 C in population centres like New York, Kansas City and Washington, D.C, as July害羞草研究所檚 oppressive 害羞草研究所渉eat dome害羞草研究所� drifted north.
The weather prompted the White House to make its second policy announcement on extreme heat in as many weeks, and a UN weather agency to proclaim it as the hottest month ever 害羞草研究所� before it was even over.
害羞草研究所淪hort of a mini-Ice Age over the next days, July 2023 will shatter records across the board,害羞草研究所� UN Secretary-General Ant贸nio Guterres told a news conference on Thursday.
害羞草研究所淭he era of global warming has ended,害羞草研究所� he said. 害羞草研究所淭he era of global boiling has arrived.害羞草研究所�
The signals couldn害羞草研究所檛 be more clear that people need to think differently about the weather, said Ashley Ward, director of the Heat Policy Innovation Hub at Duke University in Durham, N.C.
害羞草研究所淎t 30 days, we害羞草研究所檙e not talking about a heat wave anymore. We害羞草研究所檙e talking about a season. We害羞草研究所檙e talking about a marker, a shift,害羞草研究所� Ward said.
害羞草研究所淲e害羞草研究所檙e talking about a new chronic state of being for heat season. It isn害羞草研究所檛 unreasonable to think this could quite possibly be the coolest heat season of our lives.害羞草研究所�
More than 150 million U.S. residents, nearly half the country害羞草研究所檚 population, were under extreme heat alerts Friday.
The global mean surface air temperature for the first 23 days of July averaged 16.95 C, compared with the previous record of 16.63 C for July 2019. Climate action 害羞草研究所渋s not a luxury but a must,害羞草研究所� said Petteri Taalas, the UN World Meteorological Organization害羞草研究所檚 secretary-general.
In Phoenix, which has endured temperatures of 43 C or hotter for 27 straight days, emergency rooms are admitting patients for third-degree burns suffered after falling on the searing asphalt.
害羞草研究所淔olks, we really want to pretend these things are normal?害羞草研究所� President Joe Biden said Thursday as he met with the mayors of Phoenix and San Antonio to tout his latest efforts to help people contend with the conditions.
害羞草研究所淭he number 1 weather-related killer is heat. Six hundred people die annually from its effects, more than from floods, hurricanes, and tornadoes in America combined,害羞草研究所� he said.
And it害羞草研究所檚 costing the country an estimated $100 billion a year, a price tag that害羞草研究所檚 only going to continue to go up, he added.
害羞草研究所淓ven those places that are used to extreme heat have never seen it as hot as it is now for as long as it害羞草研究所檚 been.害羞草研究所�
The measures the White House announced this week included a new Department of Labor heat hazard alert system to better warn construction and agricultural workers, and tougher enforcement measures to police their employers.
The Interior Department will spend $152 million to expand water storage and delivery systems in California, Colorado and Washington, where severe drought conditions are a chronic problem.
And the National Oceanic and Atmospheric Administration will get an additional $7 million to work with universities on developing better weather forecasting models to give communities more advance warning about extreme weather.
Not good enough, the National Council for Occupational Safety and Health complained Friday.
害羞草研究所淲orkers are getting sick and dying every day from the extreme heat driven by climate change,害羞草研究所� said co-executive director Jessica Martinez.
The group called on Biden to order an emergency temporary standard to better protect workers from heat stress, establish a more stringent permanent threshold for protections and urge states to impose their own rules.
害羞草研究所淭his is no time for modest steps.害羞草研究所�
Like a number of U.S. cities, Phoenix and San Antonio are expanding efforts to deploy so-called 害羞草研究所渃ool pavement害羞草研究所� surfaces that absorb less heat, part of an effort to ease the heat-island effect that occurs in urban areas.
San Antonio is also growing as a U.S. solar energy hub 害羞草研究所� the fifth-largest producer in the country, said Mayor Ron Nirenberg 害羞草研究所� and now requires 240-volt chargers for electric vehicles in all its new single-family homes.
害羞草研究所淪ustainability and green energy are no longer four-letter words in the state of Texas,害羞草研究所� Nirenberg said.
Part of the reason long stretches of extreme heat can be so deadly is because they are insidious, Ward said.
Typically, parts of the country accustomed to summer heat, particularly in the southern U.S., have been able to cool off in the evening once the sun goes down, giving people a reprieve before the next day.
In many U.S. regions this year, however, that reprieve hasn害羞草研究所檛 been coming, thanks in part to higher-than-usual humidity.
害羞草研究所淲e害羞草研究所檝e seen some incredibly dangerous situations in the southeast where we害羞草研究所檝e had these extreme temperatures during the day, but also a failure for the temperature to drop overnight,害羞草研究所� Ward said.
Several times so far this summer in Arizona, the overnight temperature has remained oppressive, often higher than 30 C. And even in parts of the country where the daytime temperature isn害羞草研究所檛 as high, excess humidity makes it worse.
害羞草研究所淭his is 害羞草研究所� by far 害羞草研究所� one of the most dangerous circumstances, where we have both extreme temperatures in each part of the day,害羞草研究所� Ward said. 害羞草研究所淭his is in fact the worst-case scenario for health outcomes.害羞草研究所�
