We’ve simply skilled the most popular day ever recorded on Earth – for the second day in a row. The common world air temperature recorded 2 metres above Earth’s floor hit 17.18°C (62.92°F) on 4 July, in keeping with information from the Nationwide Oceanic Atmospheric Administration (NOAA) and compiled by the College of Maine.
The brand new report outstrips the earlier excessive of 17.01°C (62.62°F) set on 3 July. It makes 4 July the most popular day ever on Earth since data started.
Earlier than that, the following highest-temperature on report was recorded collectively in August 2016 and July 2022, when common world temperatures reached 16.92°C (62.46°F).
The 2 consecutive days of record-breaking world warmth confirms scientists’ warnings that 2023 is more likely to be one of many hottest years on report, as the dual results of local weather change and a warming El Nino local weather sample drive temperatures to new highs.
Robert Rohde at Berkeley Earth in California says warming within the Pacific Ocean, which heralds the beginning of an El Nino occasion, is a key driver of the excessive world temperatures.
“The El Niño occasion was formally declared by NOAA proper firstly of June,” he says. “The warming has been increasing within the Pacific and that’s more likely to be contributing to issues [temperatures] inching up a bit greater in July than in earlier months.”
Current heatwaves throughout the US, Europe and Canada may even have performed a task, he says.
This particular NOAA/Maine information set solely goes again to 1979, however it’s comparable with different information that goes again a lot additional. Rohde says he’s assured that it’s the highest ever since instrumental measurements started, across the 1850s. It’s an “anticipated milestone”, he says, given the dual drivers of local weather change and further warming from El Niño.
“We are going to maintain passing these thresholds each few years if we now have El Niño variability on prime of worldwide warming, till we get world warming beneath management,” says Rohde.

In the meantime, information from the EU’s Copernicus Local weather Change Service this week confirmed that world common temperatures in June 2023 had been 1.46°C above pre-industrial ranges, edging ever nearer to the 1.5°C threshold nations have vowed to not exceed.
BREAKING: June 2023 has blown away all prior data for the month of June, coming in at a staggering 0.16C above the prior report set in 2019.

World common air temperatures observe the seasonal cycles of the northern hemisphere, with temperatures peaking in July. That’s as a result of air temperatures fluctuate extra over land than over water, and because the northern hemisphere boasts extra land mass than the southern hemisphere, it has a bigger affect over the worldwide common.
With El Niño persevering with to construct via the remainder of the yr and excessive summer time arriving within the northern hemisphere, Rohde believes it’s seemingly that July and August may even see excessive – even report – common world temperatures. This yr is “extra seemingly than not” to be the most popular yr on report, he says.
