July ends 13-month streak of global heat

Earth’s string of 13 straight months with a new average heat record came to an end this past July — but just barely — as the natural El Nino climate pattern ebbed.

Earth’s string of 13 straight months with a new average heat record came to an end this past July as the natural El Nino climate pattern ebbed, the European climate agency Copernicus announced Thursday.

But July 2024 ‘s average heat just missed surpassing the July of a year ago, and scientists said the end of the record-breaking streak changes nothing about the threat posed by climate change.

“The overall context hasn’t changed,” Copernicus deputy director Samantha Burgess said in a statement. “Our climate continues to warm.”

Human-caused climate change drives extreme weather events that are wreaking havoc around the globe, with several examples just in recent weeks. In Cape Town, South Africa, thousands were displaced by torrential rain, gale-force winds, flooding and more. A fatal landslide hit Indonesia’s Sulawesi island. Beryl left a massive path of destruction as it set the record for the earliest Category 4 hurricane. And Japanese authorities said more than 120 people died in record heat in Tokyo.

Those hot temperatures have been especially merciless.

The globe for July 2024 averaged 62.4 degrees Fahrenheit, which is 1.2 degrees above the 30-year average for the month, according to Copernicus. Temperatures were a small fraction lower than the same period last year.

It is the second-warmest July and second-warmest of any month recorded in the agency’s records, behind only July 2023. The Earth also had its two hottest days on record, on July 22 and July 23, each averaging about 62.9 degrees Fahrenheit (17.16 degrees Celsius). Copernicus had previously identified July 21 and 22 as the hottest days, but changed that based on updated data.

During July, the world was 1.48 degrees Celsius (2.7 degrees Fahrenheit) warmer, by Copernicus’ measurement, than pre-industrial times. That’s close to the warming limit that nearly all the countries in the world agreed to in the 2015 Paris climate agreement: 1.5 degrees.

El Nino — which naturally warms the Pacific Ocean and changes weather across the globe — spurred the 13 months of record heat, said Copernicus senior climate scientist Julien Nicolas. That has come to a close, hence July’s slight easing of temperatures. La Nina conditions — natural cooling — aren’t expected until later in the year.

But there’s still a general trend of warming.

“The global picture is not that much different from where we were a year ago,” Nicolas said in an interview.

“The fact that the global sea surface temperature is and has been at record or near record levels for the past more than a year now has been an important contributing factor,” he said. “The main driving force, driving actor behind this record temperature is also the long-term warming trend that is directly related to buildup of greenhouse gases in the atmosphere.”

That includes carbon dioxide from the burning of fossil fuels such as coal, oil and natural gas.

July’s temperatures hit certain regions especially hard, including western Canada and the western United States. They baked, with around one-third of the U.S. population under warnings at one point for dangerous and record-breaking heat.

In southern and eastern Europe, the Italian health ministry issued its most severe heat warning for several cities in southern Europe and the Balkans. Greece was forced to close its biggest cultural attraction, the Acropolis, due to excessive temperatures. A majority of France was under heat warnings as the country welcomed the Olympics in late July.
