With emissions soaring, 2021 is the fifth hottest year on record | Climate Crisis News

The European Union’s Copernicus Climate Change Service said that the past seven years have been the hottest “significant range” on record.

European Union scientists said that 2021 is the fifth hottest year on record in the world, and the levels of carbon dioxide and methane in the atmosphere, which cause global warming, hit new highs.

The European Union’s Copernicus Climate Change Service (C3S) stated in a report on Monday that in records dating back to 1850, the past seven years was the world’s hottest “clear gap”. The global average temperature in 2021 was 1.1-1.2C (1.98 -2.16F) is higher than the 1850-1900 level.

The hottest years on record are 2020 and 2016.

According to the 2015 Paris Agreement, countries pledged to limit global temperature rise to 1.5 degrees Celsius (2.7 degrees Fahrenheit), and scientists said reaching this level would avoid its most serious effects. This will require emissions to be roughly halved by 2030, but so far, their fees have been higher.

As greenhouse gas emissions change the earth’s climate, the long-term warming trend continues. climate change Intensified the many extreme weather events sweeping the world in 2021, from floods in Europe, China and South Sudan to wildfires in Siberia and the United States.

CS3 Director Carlo Buontempo revealed: “2021 is another year of extreme temperatures, the hottest summer in Europe, the heat wave in the Mediterranean, not to mention the unprecedented high temperatures in North America.”

“These events clearly remind us that we need to change our approach, take decisive and effective steps to achieve a sustainable society, and work hard to reduce net carbon emissions,” Buontempo warned.

The global levels of the major greenhouse gases carbon dioxide and methane continue to climb, and both hit record highs in 2021.

Scientists say that the carbon dioxide content in the atmosphere will reach 414.3 parts per million in 2021, an increase of about 2.4 ppm over 2020.

C3S said that methane is a particularly potent greenhouse gas, and its content has soared in the past two years, but the reason is not fully understood.

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

After the 2020 COVID-19 pandemic began to temporarily decline, provisional data showed that global carbon dioxide emissions rebounded by 4.9% in 2021.

European new high

CS3 stated that last summer was the hottest year on record in Europe. The previous warm March and unusually cold April led to a significant reduction in fruit crops in countries such as France and Hungary.

In July and August, the Mediterranean heat wave triggered intense wildfires in countries such as Turkey and Greece. Sicily has set a new European high temperature of 48.8 degrees Celsius (119.84 degrees Fahrenheit), a record that has yet to be officially confirmed.

In July, heavy rains caused deadly floods in Western Europe, killing more than 200 people. Scientists have concluded that climate change has increased the likelihood of flooding by at least 20%.

In the Glasgow Climate Convention, United Nations members stated in November that they hope to control global warming at 1.5 degrees Celsius compared to the pre-industrial era. However, Climate experts say The agreement is far from enough, especially when it comes to helping protect fragile countries from the effects of global warming.
