2021 is the fifth warmest year on record, with emissions rising Climate crisis news

The EU’s Copernicus Climate Change Service says the last seven years have been the warmest “by a clear margin” since records began.

2021 was the fifth year in the world that global warming levels of carbon dioxide and methane had reached new heights, according to European Union scientists.

The EU’s Copernicus Climate Change Service (C3S) said in a report on Monday that the last seven years had been the warmest in the world “by a clear margin” in the 1850 records and that in 2021 the world average temperature was 1.1-1.2 C (1.98). -2.16F) above 1850-1900 levels.

The hottest years on record were 2020 and 2016.

Under the 2015 Paris Agreement, countries that pledged to try to limit global temperature rise to 1.5 C (2.7 F) have said scientists will avoid the worst effects. This would require a halving of emissions by 2030, but so far they have been charged higher.

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

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

“These events are reminiscent of the need to change our ways, to take decisive and effective steps towards a sustainable society, and to work to reduce net carbon emissions,” Buontempo warned.

Global levels of CO2 and methane, the main greenhouse gas, continued to rise, both of which were set in 2021.

Concentrations of atmospheric carbon dioxide (CO2) and methane (CH4) have continued to rise in 2021. This preliminary study of satellite data shows that the growth rate of methane was particularly high. See the video or link for more details https://t.co/k7OHCjlHP7 # C3S pic.twitter.com/qpcGmOPipo

Atmospheric CO2 levels will reach 414.3 per million by 2021, roughly 2.4 ppm by 2020, scientists say.

C3S said levels of methane, a particularly strong greenhouse gas, have risen in the past two years, but the reasons are not fully understood.

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

Following the temporary decline in the COVID-19 pandemic in 2020, provisional data suggest that global CO2 emissions will rise by 4.9% in 2021.

New high levels in Europe

Last summer was the hottest European record, CS3 said, with a drop in fruit harvests in countries like France and Hungary after a warm March and an unusually cold April.

In July and August, a heat wave in the Mediterranean ignited wildfires, including in Turkey and Greece. Sicily has set a high temperature of 48.8 C (119.84 F) in Europe, a record awaiting official confirmation.

More than 200 people died in July when heavy rains caused severe flooding in western Europe. Scientists concluded that climate change could cause flooding by at least 20 percent more.

In the Glasgow Climate Pact, members of the United Nations confirmed in November that they want to stop global warming at 1.5 degrees Celsius compared to pre-industrial times. However, climate experts have said that the treaty does not go far enough, especially to help protect weak nations from the effects of global warming.
