The southern hemisphere may have reached its highest recorded temperature yesterday. A station in Onslow, a small coastal town in the west of Australia, registered a suffocating temperature of 50.7 degrees in the midst of a strong heat wave that affects several southern countries, such as Argentina.
The World Meteorological Organization (WMO) has begun a meticulous review of the temperature reading. If verified, it would tie the highest record of all time set in Oodnadatta, Australia on January 2, 1960.
A huge heat dome was parked over Western Australia, with Onslow just below. The temperatures were about 11 degrees above normal at the hottest time of year.
“Given the rising temperature trends over the last few decades, it is less surprising that we are seeing extreme temperatures like those in Western Australia right now,” wrote Nina Ridder, a researcher at the Center of Excellence for Weather Extremes at the University of New York. Sydney South Wales.
Western Australia is currently coming off its third warmest December in 2021. Ridder said mean sea surface temperatures in northwestern Western Australia have also been above average – around 2 degrees higher in December 2021. and they could have had harmful effects on marine ecosystems, how to induce coral bleaching
The extreme temperature comes the same week that several of the world’s leading climate research institutions announced that the last seven years have been the hottest of recorded history. In that time, temperature records have been broken around the world. WMO has four ongoing investigations and has just completed another.
“Since the creation of the WMO Global Weather and Climate Extremes Archive in 2007, we have never had as many ongoing verifications/assessments as we currently doRandy Cerveny, who leads the climate and weather extremes team at the World Meteorological Organization, wrote in an email.
Here is a select list of verified and unverified national and international record temperatures (in recorded history) in the last two years:
According to climatologist Maximiliano Herrera, in total, ten different countries tied or broke national heat records in 2021 (Morocco, Taiwan, Tunisia and Dominica, in addition to those mentioned above).
Those ends are just scratching the surface. Outside of national or international records, unprecedented extremes are occurring in local communities and on smaller time scales as well. Cerveny said local high temperatures are “exceeded much more frequently than record low temperatures.”
Herrera documented 400 weather stations in communities or outposts around the world that set record high temperatures in 2021.
“We are seeing more frequent extreme temperatures,” Cerveny wrote. “The climate that we have experienced in recent decades is changing and we must be aware of this, and realize that these fundamental changes have consequences in our way of life.”
