Weather records are falling like dominoes around the globe this summer.

The Earth’s unofficial average temperature broke records last week. Daily high temperatures broke records in South Florida and Arizona. A Texas heat dome broke records in June and it was the planet’s warmest June on record.

The dizzying headlines are unlikely to slow down over the next few weeks, or in the years to come as climate change reshapes the world’s weather, making natural events more extreme.

“There’s a definite chance we will see record daily highs being broken a few more times over the next four to six weeks,” said Robert Rohde, lead scientist for Berkeley Earth, an independent non-profit focused on climate analysis.

Here’s why:

Here’s a breakdown to understand the records and how they’re calculated and set.

Could this year be the warmest on record?

“It is actually almost a certainty that this will be the warmest year globally,” Michael Mann, a climate scientist and professor at the University of Pennsylvania, told USA TODAY. “We can expect that combination of factors to supercharge weather events this summer in the form of extreme heat waves, drought, wildfire and flooding events.”

A month ago, after processing May temperature data, Berkeley Earth put the odds of a record warm 2023 at 54%, slightly better than a coin flip, Rohde said.   

Updated odds haven’t been calculated yet, but “now that June has come up as a scorcher, the probability has certainly increased,” Rohde told USA TODAY. It’s now “more likely than not that 2023 will set a new record for the warmest annual average.”
