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含羞草研究社檚 oppressive 含羞草研究社渉eat dome含羞草研究社� 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 含羞草研究社� before it was even over.
含羞草研究社淪hort of a mini-Ice Age over the next days, July 2023 will shatter records across the board,含羞草研究社� UN Secretary-General Ant贸nio Guterres told a news conference on Thursday.
含羞草研究社淭he era of global warming has ended,含羞草研究社� he said. 含羞草研究社淭he era of global boiling has arrived.含羞草研究社�
The signals couldn含羞草研究社檛 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.
含羞草研究社淎t 30 days, we含羞草研究社檙e not talking about a heat wave anymore. We含羞草研究社檙e talking about a season. We含羞草研究社檙e talking about a marker, a shift,含羞草研究社� Ward said.
含羞草研究社淲e含羞草研究社檙e talking about a new chronic state of being for heat season. It isn含羞草研究社檛 unreasonable to think this could quite possibly be the coolest heat season of our lives.含羞草研究社�
More than 150 million U.S. residents, nearly half the country含羞草研究社檚 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 含羞草研究社渋s not a luxury but a must,含羞草研究社� said Petteri Taalas, the UN World Meteorological Organization含羞草研究社檚 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.
含羞草研究社淔olks, we really want to pretend these things are normal?含羞草研究社� 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.
含羞草研究社淭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,含羞草研究社� he said.
And it含羞草研究社檚 costing the country an estimated $100 billion a year, a price tag that含羞草研究社檚 only going to continue to go up, he added.

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.
含羞草研究社淲orkers are getting sick and dying every day from the extreme heat driven by climate change,含羞草研究社� 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.
含羞草研究社淭his is no time for modest steps.含羞草研究社�
Like a number of U.S. cities, Phoenix and San Antonio are expanding efforts to deploy so-called 含羞草研究社渃ool pavement含羞草研究社� 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 含羞草研究社� the fifth-largest producer in the country, said Mayor Ron Nirenberg 含羞草研究社� and now requires 240-volt chargers for electric vehicles in all its new single-family homes.
含羞草研究社淪ustainability and green energy are no longer four-letter words in the state of Texas,含羞草研究社� 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含羞草研究社檛 been coming, thanks in part to higher-than-usual humidity.
含羞草研究社淲e含羞草研究社檝e seen some incredibly dangerous situations in the southeast where we含羞草研究社檝e had these extreme temperatures during the day, but also a failure for the temperature to drop overnight,含羞草研究社� 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含羞草研究社檛 as high, excess humidity makes it worse.
含羞草研究社淭his is 含羞草研究社� by far 含羞草研究社� one of the most dangerous circumstances, where we have both extreme temperatures in each part of the day,含羞草研究社� Ward said. 含羞草研究社淭his is in fact the worst-case scenario for health outcomes.含羞草研究社�
