Climate change has made the last eight years the hottest record

According to an analysis of world meteorological stations and oceanographic measurements released Thursday by NASA’s Goddard Institute for Space Studies and the US National Oceanic and Atmospheric Administration, the last eight years have been the hottest in the world record up to 1880 and the sixth in 2021. It was a hot year. Atmospheric control.

Last year’s average global temperature was just over 1 degree Celsius higher than the 1880-1900 average.

Berkeley Earth, a non-profit organization that looks at observatories and oceanographic data, discovered last year that it was virtually linked to the fifth hottest years of 2015 and 2018.

NASA, NOAA, and Berkeley Earth are three of the five major research groups conducting temperature analysis. The EU Copernicus Climate Change Service, which released its results last week, evaluates satellites, surface records, balloons and other measurements and estimates world figures from them. According to this analysis, 2021 is the fifth hottest year since 1979.

Scientists aggregate these rankings each year. Another research center, the Met Office, will report the data shortly. Researchers quickly point out that the annual results reflect the natural statistical noise of the climate system. For example, 2021 is cooler than it was a few years ago as the temperature dropped due to the cooling of the El Niño phenomenon in the equatorial Pacific. The 2010s were the hottest decade on record. Since the 1960s, it has become hotter on average every 10 years.

In recent years, scientists have become more direct with policy makers and the general public. Guidance that countries should eliminate the impact of emissions by 2050 and halve emissions by 2030 has been a global policy rally in the last three years.

The Met Office released an estimate this week that the world must reduce carbon dioxide pollution by 20% over the next five years in order to have a reasonable chance to limit global warming to 1.5 ° C. Last year’s emissions increased by 4.9%, almost reaching 2019 levels, after a significant pandemic-related decline in 2020.

2021 was flooded with anomalous climatic events, including the most dramatic heat waves ever observed, historic floods in Central Europe, and deadly cyclones and floods in India. .. Munich Re has calculated the cost of the 2021 climate disaster to be $ 280 billion worldwide.
