New York: Earth reached the sixth hottest year on record in 2021, according to several newly released temperature measurements.
And scientists say that the extraordinary warm year is part of a long -term warming trend that shows signs of rapid.
Two American science agencies – NASA and the National Ocean and Atmospheric Administration – and a private measuring group on Thursday released their calculations for last year’s global temperature, and all said that it was not far behind Ultra -Hot 2016 and 2020.
The 2021 in six separate calculations found from the late 1800s since the late 2021 was between the fifth and the seventh hottest years. NASA said that 2021 tied the sixth hottest with 2018, while NOAA is in sixth position before 2018.
Scientists say that a la neena – the natural cooling of some parts of the central Pacific that replaces the weather patterns globally and brings chilli deep sea water on the surface – as its flip side as its flip side, El Nino promoted them in 2016.
Nevertheless, he said that the hottest la Nina was the hottest year on 2021 records and that year did not represent a cooling of human-inviting climate change, but provided more of the same heat.
“So it’s not enough to be the hottest on record as the headline-dominating, but give it one and a few years and we will see one of them” Record, the climate scientist Zeke said. Gentleman Among the Berkeley Earth Monitoring Group, 2021 is also ranked sixth. “This is a long -term trend, and it is an indomitable march upward.”
Gavin ShamitClimate scientists who are head of NASA’s temperature team, said, “Long -term trend is very clear. And this is because of us. And it is not going to stop increasing the amount of carbon dioxide in the atmosphere.”
The last eight years have been the eight hottests on records, NASA and NOAA have agreed data. Global temperature, on average over a 10 -year period to remove natural variability, is about 2 degrees (1.1 ° C) warmer than 140 years ago, their data shows.
Other 2021 measures came from Satellite Measurement by Japanese Measurement and Copernicus Climate Change Services in Europe and satellite measurement by Alabama University in Huntsville.
About eight to 10 years ago there was such a specific leap in temperature that scientists have started to see if the increase in temperature is increasing rapidly. Both Schmidt and the courage said that initial signs point towards him, but it is difficult to know to ensure.
“I think you can see acceleration, but is it statistically strong, it’s not quite clear,” Schmit said in an interview. “If you see the last 10 years in the last 10 years, how many of them have been above the trend line for the last 10 years? Almost all of them.”
According to the NOAA, the global average temperature last year was 58.5 degrees (14.7 Celsius). In 1988, the then Chief Climate Scientist of NASA James Hansen When he testified to the Congress about global warming in a year, the headlines of the time made the most hot on record. Now, rank as the 28th hottest year on a 57.7 degree (14.3 Celsius) records of 1988.
Last year, 1.8 billion people in 25 Asian, African and Middle Eastern countries were the hottest years on records including Berkeley Earth, including China, Nigeria, Bangladesh, Iran, Myanmar and South Korea.
The deep ocean, where most of the heat is stored in the seas, also created a record for heat in 2021, according to a separate new study.
“In addition to endangering ocean warming, coral bleaching and threatening, in addition to endangering the population of sea and fish, we rely for about 25% of our protein intake globally, Antarctic snow shelves are unstable and there is a massive danger … if we do not work, the sea level increases.”
The last time the Earth had a cooler compared to the normal year by calculating NOAA or NASA. 1976 meant 69% of people on the planet – more than 5 billion people under the age of 45 – have never experienced such a year, based on United Nations data.
