2021 was the fifth hottest year on record as emissions rise | Climate crisis News

The EU’s Copernicus climate change service says the past seven years have been “by far” since the records began.

2021 was the fifth hottest year on record in the world, as levels of carbon dioxide and global warming methane in the atmosphere hit new highs, Union scientists have said European.

The EU’s Copernicus Climate Change Service (C3S) said in a report on Monday that the past seven years have been the hottest in the world “by far” in records dating back to 1850 and that the average global temperature in 2021 was 1.1 to 1.2 ° C (1.98 ° C). -2.16F) above the 1850-1900 levels.

The hottest years on record were 2020 and 2016.

Countries pledged under the 2015 Paris Agreement to try to limit the increase in global temperature to 1.5 ° C (2.7 ° F), the level according to scientists would avoid its worst impacts . That would require emissions to be roughly halved by 2030, but so far they’ve charged more.

As greenhouse gas emissions change the planet’s climate, the long-term warming trend has continued. Climate change has exacerbated many of the extreme weather events that swept the world in 2021, from flooding in Europe, China and South Sudan, to wildfires in Siberia and the United States.

“The year 2021 was another year of extreme temperatures with the hottest summer in Europe, heat waves in the Mediterranean, not to mention the unprecedented high temperatures in North America”, revealed Carlo Buontempo, director of CS3.

“These events are a stark reminder of the need to change our habits, to take decisive and effective measures towards a sustainable society and to work towards the reduction of net carbon emissions,” Buontempo warned.

Global levels of CO2 and methane, the main greenhouse gases, continued to climb and both reached record highs in 2021.

CO2 levels in the atmosphere reached 414.3 parts per million in 2021, up about 2.4 ppm from 2020, the scientists said.

C3S said levels of methane, a particularly potent greenhouse gas, have jumped over the past two years, but the reasons are not fully understood.

Methane emissions range from oil and gas production and agriculture to natural sources like wetlands.

After a temporary drop in 2020 at the start of the COVID-19 pandemic, provisional data suggests global CO2 emissions rebounded 4.9% in 2021.

New heights in Europe

Last summer was the hottest on record in Europe, CS3 said, after a hot March and an unusually cold April that decimated fruit crops in countries like France and Hungary.

In July and August, a Mediterranean heat wave fueled intense forest fires in countries like Turkey and Greece. Sicily has set a new European temperature record of 48.8 ° C (119.84 ° F), a record awaiting official confirmation.

In July, more than 200 people died when torrential rains triggered deadly floods in Western Europe. Scientists concluded that climate change has made flooding at least 20% more likely.

In the Glasgow Climate Pact, members of the United Nations said in November that they wanted to stop global warming at 1.5 degrees Celsius compared to pre-industrial times. However, climate experts have said the pact does not go far enough, especially in helping to protect vulnerable countries from the effects of global warming.
