2021 is fifth hottest year on record as emissions surge Climate Crisis News

The European Union’s Copernicus Climate Change Service said the past seven years had been the warmest on record with a “clear gap”.

EU scientists say 2021 will be the world’s fifth-warmest year on record, while levels of the planet-warming carbon dioxide and methane in the atmosphere hit record levels.

The past seven years have been “clearly ahead” of the world’s warmest years in records going back to 1850, with an average global temperature of 1.1-1.2C in 2021, the European Union’s Copernicus Climate Change Service (C3S) said in a report on Monday. (1.98 -2.16F) above the 1850-1900 level.

The warmest years on record were 2020 and 2016.

Countries pledged under the 2015 Paris Agreement to limit global temperature rise to 1.5 degrees Celsius (2.7 degrees Fahrenheit), a level scientists say will avoid its worst effects. This would require roughly halving emissions by 2030, but so far they have charged more.

The long-term warming trend continues as greenhouse gas emissions alter the Earth’s climate. climate change Adding to the many extreme weather events that will sweep the world in 2021, from floods in Europe, China and South Sudan, to wildfires in Siberia and the United States.

“2021 will be another year of extreme temperatures, the hottest summer in Europe, a heatwave in the Mediterranean, not to mention unprecedented heat in North America,” revealed CS3 Director Carlo Buontempo.

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

Global levels of the main greenhouse gases carbon dioxide and methane continue to climb and hit record highs in 2021.

Scientists say carbon dioxide levels in the atmosphere will reach 414.3 parts per million by 2021, an increase of about 2.4 ppm from 2020.

Methane, a particularly potent greenhouse gas, has increased over the past two years, but the reasons for it are not fully understood, C3S said.

Methane emissions range from oil and gas production and agriculture to natural resources such as wetlands.

After a temporary dip in 2020 after the start of the COVID-19 pandemic, provisional data show that global carbon dioxide emissions rebounded by 4.9% in 2021.

new high in europe

Last summer was the hottest on record in Europe after a warm March and an unusually cold April led to reduced fruit crops in countries such as France and Hungary, CS3 said.

In July and August, Mediterranean heatwaves sparked intense wildfires in countries such as Turkey and Greece. Sicily recorded a new European temperature of 48.8C (119.84F), a record awaiting official confirmation.

Torrential rains caused deadly flooding in Western Europe in July, killing more than 200 people. The scientists concluded that climate change made flooding at least 20 percent more likely.

In the Glasgow Climate Pact, UN members confirmed in November that they want to limit global warming to 1.5 degrees Celsius compared to pre-industrial levels. However, climate experts say The deal doesn’t go far enough, especially when it comes to helping protect vulnerable countries from the effects of global warming.
