Summer heat: continuous heat wave broke records, spirits

From the normally cold Russian Arctic to the traditionally sweltering American South, large parts of the Northern Hemisphere continued to scorch from extreme heat as summer began to resemble the dog days of August.

A heat dome of three-digit temperatures in several locations with high humidity, oscillating from west to east in the United States. According to the National Weather Service, on Thursday at least eight states had set or broke the high temperature mark of 100 degrees Celsius (37.8 degrees Celsius) and at least nine put 30 million Americans under some sort of heat advisory. was.

The most uneasiness on Thursday came after 12 states broke the 100-degree mark on Wednesday and 21 records were either broken. Since June 15, at least 113 automated weather stations have tied or broken warm temperature records. Scientists say this early baking has all the signs of climate change.

“It’s easy to look at these figures and forget the immense misery they represent. Those who can’t afford air conditioning and those who work outside have only one option but to suffer.” ,” said Texas A&M climate scientist Andrew Dessler, who was in College Station, where the temperature was recorded at 102 degrees Celsius (38.9 degrees Celsius). Thursday. “Those of us with air conditioning don’t suffer physically. Maybe, but we are prisoners inside the house.”

Chicago has changed its cooling rules after three deaths.

In Macon, Georgia, the temperature rose from 64 degrees (17.8 degrees Celsius) to 105 (40.6 degrees Celsius) in just nine hours on Wednesday. Then on Thursday the temperature reached 104 (40 degrees Celsius), which is the day’s record. Even Minneapolis scored 100 on Monday.

National Weather Service meteorologist Mark Chenard said at the Weather Prediction Center that probably only the Pacific Northwest and Northeast are left with a heat wave. On Thursday, Texas, Louisiana, Mississippi, Alabama, Georgia, Florida, Arizona and California all hit at least 100. The same states jumped to 100 on Wednesday, joining North and South Carolina, Kentucky and Tennessee.

“It’s persistent,” Chenard said. “It’s been over a week and it will continue in some aspects.”

It’s not just America

The Russian city of Norilsk, above the Arctic Circle, recorded 89.6 °C (32 °C) on Thursday for its warmest June day on record, and in any month on record, according to global temperature record tracker Maximiliano Herrera. Tied up for your hottest day ever. Several Japanese cities hit their hottest June temperatures, including the city of Noboka at 97 (36.1 °C), while Turpan in China recorded 114 °C (46.5 °C). Herrera said it’s so crazy he doesn’t have time to eat or sleep, just track broken records and extreme heat.

A European heat wave has also caused fire problems in Germany and Spain.

What is happening with this early heat wave is “in line with what we expect in a constantly warming world,” said Victor Jancini, a professor of meteorology at Northern Illinois University.

“These temperatures coincide with only 2 degrees Fahrenheit (1.1 degrees Celsius) of global warming and we are on track for 4 degrees Fahrenheit (2.2 degrees Celsius) more warming this century,” Dassler said. “I really can’t imagine how bad it would be.”

In Raleigh, North Carolina, it hit 100 on Wednesday and the city usually only gets 100 degrees a day a year, state meteorologist Cathy Dallow said, but it comes much later than that.

“Many people in the southeastern US do not have access to adequate or stable cooling or cannot afford to use their home cooling systems. Heat morbidity and mortality in a changing climate is one of our greatest public health risks. Is. “

Chenard said there could be some cooling in some places, including the north central part of the country, over the weekend or till Monday. But above-normal temperatures are forecast for “at least the first half of July” and he said it is likely the entire summer will be warmer than normal.
