According to NOAA climatologist Ahira Sanchez-Lugo, the last July of 2015-2021 was the hottest July on record. Last month was 1.67 degrees (0.93 degrees Celsius) warmer than the 20th century average for that month.

“In this case, number one is the worst place,” NOAA administrator Rick Spinrad said in a press release. “This new record adds a disturbing and destructive path that climate change has set on Earth.”

“this is Climate change“This is a sign of summer admiration for unprecedented heat, drought, wildfires and floods,” said Michael Mann, a climate scientist at Pennsylvania State University.

Earlier this week, the prestigious United Nations Scientific Committee Warning of worsening climate change Coal, oil, Natural gas And other human activities.

According to Sanchez Lugo, warming in western North America and parts of Europe and Asia has caused record heat. The world’s temperature was slightly above the record, but it was the northern hemisphere’s temperature that smashed it, she said.

“One month alone doesn’t make much sense, but this year was the year of La Niña, the warmest temperature on record … consistent with the patterns we’ve seen in most of the last decade,” he said. Donald Wuebbles, Professor of Meteorology, University of Illinois.

The world set a record in July, The United States tied for the 13th time The hottest July on record.
