Climate change: Scientists say the last seven years have been the hottest on record “by a clear margin”.

According to him, the last seven years have been the hottest ever recorded globally “by a clear margin”. Results Scientists with the European Union’s Copernicus climate change service released on Monday. Although 2021 was not as hot as in recent years, Scientists warn that global Greenhouse gas emissions The increase continues.

Last year, researchers said it was 2020 “Effectively tied” For the hottest year on record – just behind 2016, which took first place. Now 2021 is ranked fifth, followed by 2015 and 2018.

According to various datasets, the estimated annual change in global air temperature at an altitude of two meters over the industrial period (left hand axis) and 1991-2020 (right hand axis).

But while 2021 may be a bit colder than 2020, that doesn’t mean it will Climate change Are decreasing. Carbon dioxide levels Summarizing the results, it reached a world record for this year, according to a press release, containing a few megatons of carbon fuel that was released from a wildfire. Methane Concentration also reached record levels.

“The amount of carbon dioxide and methane is increasing year by year and is showing no signs of abating,” said Vincent-Henry Peuch, director of the Copernicus Atmosphere Monitoring Service. “Only with the support of observational evidence can we make a real difference in our fight against climate change.”

The heat in Europe last summer was particularly oppressive. The continent experienced its hottest on record, and Sicily breaks European record For the highest recorded temperature when it reached 119.8 degrees Fahrenheit (although the results have not yet been confirmed by the World Meteorological Organization).

Hot, dry weather before “severe and long” Forest fire I Turkey, Greece, Italy and other countries, said Copernicus researchers.

Meteorologists say. Global warming Also Increases the likelihood and severity of disasters. Like a flood that killed. More than 200 people When last summer in Germany, Belgium and the Netherlands The river overflowed And Kept roaring in the cities.Destroying homes and historic structures that spanned centuries. A Belgian government minister described the floods Brussels Times As “our country has one of the biggest natural disasters ever.”

The worst floods in Europe’s history have killed 180 people.


North America also felt the effects of this summer, which recorded the warmest June ever for the continent. The hottest summer On record for the United States Hundreds of deaths Were attributed to one. Extreme heat wave In the Pacific Northwest and British Columbia, Canada.

“I was worried people were going to think of it as just a problem, but it really turned out to be fatal,” Dr. Jennifer Vince, a health officer at Multnomah County, Oregon, told CBS News at the time.

Hot, dry conditions make another year devastating. Forest fire Across the West.

Carlo Bontempo, director of the Copernicus Climate Change Service, said the findings “are a clear reminder of the need to change our ways, take decisive and effective steps towards a sustainable society and work to reduce pure carbon emissions.” . “
