Scientists Say 2020 and 2016 are the Hottest Years on Record

Scientists Say 2020 and 2016 are the Hottest Years on Record

They have recorded in recent years records of heat and huge fires.

2020 tied 2016 as the hottest year ever recorded for the Earth's surface, according to a climate analysis released Thursday by NASA and the U.S. National Oceanic and Atmospheric Administration (NOAA).

The Earth's surface temperature in 2020 equalled 2016 as the warmest on record, the United States space agency NASA said yesterday, using the latest data from ground and sea stations and its fleet of satellites.

He pointed out that at 1.2 degrees of warming above pre-industrial levels, the world is already witnessing unprecedented weather extremes in every region and on every continent.

The other one, TOI-561b, is a hot and rocky exoplanet known as a super-Earth, which is about 50% larger than Earth and has three times the mass, orbiting one of the oldest stars in the Milky Way galaxy, but it has an average surface temperature around 3,140 degrees Fahrenheit.

'Making peace with nature is the defining task of the 21st century. "It must be the top priority for everyone, everywhere".

With regards to exactly where 2020 falls in the record books, the results may vary depending on who you ask.

The data sets used by the WMO.

All five datasets surveyed by WMO showed that 2011-2020 was the warmest decade on record, and NOAA said the seven warmest years since record-keeping began in 1880 have occurred since 2014.

According to Taalas, the temperature ranking of individual years represents only a snapshot of a much longer-term trend. The past four decades have all been warmer than the one before.

The year 2020 was one of the three warmest years on record and rivalled 2016 for the top spot, indicating the pace of the "human-induced" climate change which is now as powerful as the force of nature, the United Nations weather agency has said.

"The exceptional heat of 2020 is despite a La Niña event, which has a temporary cooling effect", Taalas said.

However, it was a particularly bad year climate-wise, too - it saw prolonged heat in the Arctic and the busiest Atlantic hurricane season ever - earning it a place among the three hottest years on record, according to data from the UN's World Meteorological Organization (WMO).

The news is "yet another stark reminder of the relentless pace of climate change, which is destroying lives and livelihoods across our planet", U.N. Secretary General Antonio Guterres said.

The WMO's consolidated global temperature update incorporates information from five leading worldwide sets of data.

As in previous years, there were significant socio-economic impacts in 2020.

The new data lowers 2019 to the third-hottest year on record. And Siberian wildfires and temperatures in Arctic Russia were some of the most extreme on the planet. That's a mere 0.04 degrees cooler than experts recorded in 2016.

"The trend is concerning because the top 10 warmest years on record have all occurred since the year 2000 and the top six warmest years have all happened in the last six years", she says.
