NASA heat map reveals dangerously high July temperatures across the US

A new map published by NASA has revealed the intensity of the heat in the United States in July.

The animated map, created using satellite data and climate modeling, is awash in deep red as brutally high temperatures hit the country from Texas to California and New York to Florida.

The sombre animation is a stark reminder of the dangerous heat wave the US is facing this summer, a consequence of the worsening climate crisis.

In July, virtually all of the US recorded above-average temperatures, NASA said. In total, more than 150 million people – nearly half of the country – faced warnings or warnings as high-pressure “heat domes” trapped hot air to create persistent heat waves.

On the map, heat waves in the Southeast, Northeast and Northwest are clearly visible. But what really stands out is the constant dark red heat in the southern plains states of Texas, Oklahoma and Kansas, which have seen repeated days with temperatures of 38 degrees Celsius or higher.

Temperatures on the plains reached 115F (46C), NASA revealed. When combined with the humidity, the temperature in some places felt like 120F (49C).

At one point, 100 million Americans were under heat alerts or alerts at the same time as high temperatures dropped in the south and northeast, the most densely populated region in the country.

At least 43 places had the hottest July on record, according to axiosincluding many cities in Texas.

And the heat was often unrelenting. NASA reported that Utah saw 16 days with temperatures at or above 100F (38C) and Newark, New Jersey, scored five straight days with temperatures in the triple digits — both records.

Toward the end of July, a heat wave hit the Pacific Northwest, leading to up to 20 deaths in Oregon and Washington. While not as disastrous or intense as last year’s heat dome in those states, which killed hundreds of people when temperatures reached 120F (49C), this year’s heat wave has demonstrated again just how vulnerable the normally temperate region is to extremes. of heat.

But the heat isn’t over yet. Millions of Americans are under heat alerts or alerts again this week as temperatures in the southern, central and northeastern US hit or above 100F (38C).

Europe also experienced a record heat wave last month. Temperatures in the UK reached 40C (104F) for the first time on record and extreme heat killed nearly 2,000 people in Spain and Portugal.

Heat waves are becoming hotter and more frequent due to the climate crisis, according to the UN Intergovernmental Panel on Climate Change, the world’s leading authority on climate science.

The world has warmed about 1.1°C above pre-industrial temperatures. If the planet reaches 2°C warming, the heat waves that used to occur once every 10 years would happen every two years, the panel says.

July 2021 was the hottest month ever recorded on Earth, according to the US National Oceanic and Atmospheric Administration (NOAA). No data yet available for this month of July.
