This has resulted in the Earth’s temperature now 1.1°C warmer than it was at the end of the 19th century, making the last decade the warmest on record, and thus our urban capital suffered devastation.

Similarly, the World Meteorological Organization (World Meteorological Organization) It shows that carbon dioxide (CO2) increased by 147%, methane (CH4) by 259%, and nitrous oxide (N2O) by 123%. These increases make climate change more severe, temperatures rise and extreme weather events multiply.

“The future well-being of mankind is at stake”, WMO Secretary-General Petteri Taalas confirmed it on Monday.

temperature rise trend

Report from NASA and the National Oceanic and Atmospheric Administration (NOAA for its English acronym) detail that the temperature of the Earth’s surface and oceans over the past year was 58.5 degrees Fahrenheit, which means 33.5 degrees Fahrenheit above the twentieth century average.

Edel Sepulveda, a scientist at NASA’s Goddard Space Flight Center, He explained to EFE that global warming is caused by the emission of gases into the atmosphere such as carbon dioxide that trap radiation and produce the so-called greenhouse effect on Earth.

“There is a broad consensus that humans are causing global warming and there is no doubt about it. The effects of this warming are not in the future, but are already recognizable.” .

According to the world, High temperature “Main Ingredient” for heat waves Like the ones the US experienced last summer, so did wildfires and droughts.

Higher temperatures also generate more vapor in the atmosphere which leads to heavy rains and floods. Like what happened in Germany, or sea level rise due to the melting of the poles.

NASA warned in its report that The amount of heat stored in the upper levels of the ocean hit a record high in 2021, surpassing the 2020 mark.
