The hottest June on Earth — a global issue

“Unfortunately, the latest figures from the Copernicus Climate Change Service Temporary exceedances of 1.5°C will become more frequentWorld Meteorological Organization (World Meteorological Organization) Secretary General Celeste Sauro.

The key 1.5°C threshold refers to the increase in temperature above pre-industrial levels that began after 1850.

Long-term perspective

“but, It is important to emphasize that a temporary violation does not mean that the 1.5°C target will not be met permanently. “This refers to long-term warming over at least 20 years,” she added.

Efforts are underway to limit the Earth’s average surface temperature to 1.5 degrees by the end of this century. Paris AgreementIt came into effect in 2016.

The scientific community has warned that warming of more than 1.5 degrees could lead to more severe climate change impacts and extreme weather, highlighting the importance of less than 1 degree change.

for example, 0.1 degree According to the World Meteorological Organization (WMO), the UN’s weather agency, this increase has caused “a clear increase in the intensity and frequency of temperature and precipitation extremes in some regions, as well as agricultural and ecological drought.”

Extreme Weather Patterns

The WMO warns that even at today’s levels of warming, the world faces devastating climate impacts: more extreme heatwaves, precipitation events, droughts, shrinking glaciers and accelerated sea-level rise are already devastating the planet.

Extreme heat causes the highest mortality rates of any extreme weather event, Between 2000 and 2019, heatstroke caused an estimated 489,000 deaths per year.according to, 2023 WMO Report.

This sea surface temperature was also the hottest ever recorded for a June month. The record-breaking temperatures are “of great concern for important marine ecosystems and marine life.” It also provides the energy that powers tropical cyclones. “Just like with Hurricane Beryl,” Sauro said.

Sea ice at both poles has also been affected, with satellite data showing that in June Arctic sea ice was 3% below average, while Antarctic sea ice was 12% below average.

Highlights from around the world

Globally, southeastern Europe and Turkey experienced the greatest warming above average.

Outside Europe, the warmest average temperatures were recorded in eastern Canada, the western United States, Mexico, Brazil, northern Siberia, the Middle East, northern Africa, and western Antarctica.

Below-normal temperatures in the eastern equatorial Pacific indicate the La Niña phenomenon is underway. Temperatures over the ocean remained abnormally high Across many regions.

“Even if this particular sequence of extremes does end someday, new records will undoubtedly be broken as the climate continues to warm,” said Carlo Buontempo, director of the Copernicus Climate Change Service.

“This is inevitable unless we stop emitting greenhouse gases into the atmosphere and oceans,” he added.
