The last 8 years the warmest ever

From 2015 to 2022: the last 8 years have been the warmest ever recorded on planet earth. World Meteorological Organization has released a new report at COP27 in Sharm el-Sheikh, Egypt. The decisions and measures that will be taken during the various days of work, which will officially go on until November 18, will in fact be decisive for the fight against the climate crisis, which is about to lead to a catastrophe for the whole of humanity.

The last eight years have been the hottest ever despite the impact of La Niña starting in 2020, which has continued until today. Petteri Taalas, secretary general of the WMO, explained: "The greater the warming, the worse the consequences.

Today we have such high levels of carbon dioxide in the atmosphere that the 1.5 ° C target of the Paris Agreement is to It is barely within reach. It is already too late for many glaciers and melting will continue for hundreds if not thousands of years, with major implications for water security.

The rate of sea level rise has doubled over the past 30 years. we still measure in terms of millimeters per year, adding half a meter to 1 meter per century and this is a long-term and serious threat to many millions of inhabitants of coasts and low states."

The melting of the ice, especially that of the poles, is responsible for the rise in sea level in the thirty years between 1993 and 2022, with a sharp rise in recent years.
Despite the effects of La Niña, we still encountered summers with record and average temperatures well above seasonal ones, such as those recorded in recent weeks.

Due to the aforementioned phenomenon, 2022 will not be the hottest year ever, but according to the WMO it will probably reach the fifth or sixth. The trend shows a constant and very dangerous increase. The annual increase in methane concentration was the highest ever recorded, and in 2022 we reached 420 parts per million of carbon dioxide in the air.

Today we emit more than 55 billion tons of greenhouse gases a year into the atmosphere, while in 2015, when the historic Paris Climate Agreement was signed, there were about 50 billion.
