It’s official. July was the hottest month on record. By far

July’s global average temperature of 16.95 degrees Celsius (62.51 degrees Fahrenheit) was a third of a degree Celsius (six tenths of a degree Fahrenheit) higher than the previous record set in 2019, Copernicus Climate Change Service announced Tuesday. Normally global temperature records are broken by hundredths or a tenth of a degree, so this margin is unusual.

The United States is now at a record 15 different weather disasters that caused at least $1 billion in damage this year, the National Oceanic and Atmospheric Administration announced Tuesday. It’s the most mega-disasters through the first seven months of the year since the agency tracked such things starting in 1980, with the agency adjusting figures for inflation.

“These records have dire consequences for both people and the planet exposed to ever more frequent and intense extreme events,” said Copernicus deputy director Samantha Burgess. There have been deadly heat waves in the Southwestern United States and Mexico, Europe and Asia. Scientific quick studies put the blame on human-caused climate change from the burning of coal, oil and natural gas.

“Climate change is here. It is terrifying. And it is just the beginning,” Guterres said. “It is still possible to limit global temperature rise to 1.5C [above pre-industrial levels], and avoid the very worst of climate change. But only with dramatic, immediate climate action.”

Guterres’s comments came after scientists confirmed on Thursday that the past three weeks have been the hottest since records began and July is on track to be the hottest month ever recorded.

The new study by World Weather Attribution – a research group comprised of international climatologists – has found that the deadly hot spells in the American Southwest and Southern Europe could not have happened without the continuing build up of warming gases in the air.

These unusually strong heat waves are becoming more common, Tuesday’s study said. The same research found the increase in heat-trapping gases, largely from the burning of coal, oil and natural gas has made another heat wave — the one in China — 50 times more likely with the potential to occur every five years or so.

A stagnant atmosphere, warmed by carbon dioxide and other gases, also made the European heat wave 2.5 degrees Celsius hotter, the one in the United States and Mexico 2 degrees Celsius warmer and the one in China one 1 degree Celsius hotter, the study found.

As Earth sizzles, climate denialists rearrange deck chairs

The problem is known. It has been known for generations, to scientists and to the oil, gas and coal companies who researched and then concealed the lethal effects of their product. Simply put, our social and political economy, structured around burning fossil fuels, heats the earth. The chief culprits in this profligate burning are wealthy countries and their massive organizations like the American military. Small, poor countries have small carbon footprints. This deadly pollution cannot be blamed on them or their so-called excessive birth-rate.

As anyone who’s experienced the weather lately knows, the situation is already bad. The world had its hottest week on record at the start of the month, according to preliminary data, with heatwaves still smashing local records across the Northern Hemisphere. And that’s just one way climate change is bringing on dangerous new extremes.

Today, the planet is about 1.1 degrees Celsius hotter than it was before the Industrial Revolution, thanks to carbon dioxide emissions from burning fossil fuels. It’s what’s driving more intense heatwaves, wildfires, storms, and sea level rise. That’s why world leaders agreed, as part of the landmark Paris agreement, to keep the planet from warming much more than it already has. Every fraction of a degree comes with more severe consequences.

The heat index reached 67℃ (152℉) at the Persian Gulf International Airport in Iran — near the limit for human survival

Persian Gulf International Airport in Iran reported a heat index of 152°F (66.7°C) today at 12:30 pm.

In recent days, China set an all-time high of nearly 126 degrees Fahrenheit, while Death Valley hit 128 degrees, two shy of the highest reliably measured temperature on Earth. Phoenix experienced a record-breaking 19th consecutive day at or above 110 degrees Tuesday. And in the Middle East, the heat index reached 152 degrees, nearing — or surpassing — levels thought to be the most intense the human body can withstand.
