Record for hottest day ever recorded on Earth broken twice in a row

We have 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 accordance with information from the National Oceanic Atmospheric Administration (NOAA) and compiled by the University of Maine.

The new document 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.

Before that, the following highest-temperature on document was recorded collectively in August 2016 and July 2022, when common world temperatures reached 16.92°C (62.46°F).

The two consecutive days of record-breaking world warmth confirms scientists’ warnings that 2023 is more likely to be one of many hottest years on document, 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 event was officially declared by NOAA right at the start of June,” he says. “The warming has been expanding in the Pacific and that is likely to be contributing to things [temperatures] inching up a bit higher in July than in previous months.”

Recent heatwaves throughout the US, Europe and Canada will 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 is an “expected milestone”, he says, given the dual drivers of local weather change and further warming from El Niño.

“We will keep passing these thresholds every few years if we have El Niño variability on top of global warming, until we get global warming under control,” says Rohde.

Meanwhile, information from the EU’s Copernicus Climate Change Service this week confirmed that world common temperatures in June 2023 have 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 document set in 2019.

Global common air temperatures comply with the seasonal cycles of the northern hemisphere, with temperatures peaking in July. That is 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 by means of the remainder of the 12 months and excessive summer time arriving within the northern hemisphere, Rohde believes it’s probably that July and August will even see excessive – even document – common world temperatures. This 12 months is “more likely than not” to be the most popular 12 months on document, he says.
