The Year 2021 Was The Sixth-Warmest Year On Record.

Amazing, the year 2021 was sixth-hottest year since records began

The past eight years were the eight hottest since record-keeping began in 1880, said US government scientists.

US government scientists have said 2021 was the sixth-warmest year on record, and they are putting the blame squarely on climate change.

On average, 2021 was 1.51 degrees Fahrenheit (0.84 degrees Celsius) hotter than the baseline between 1901 and 2000, the National Oceanic and Atmospheric Administration (NOAA) said in a report issued on Thursday.

NASA, the North American Space Agency, came to similar conclusions in a report released in conjunction with data from NOAA. In its assessment, NASA said 2021 was tied for the sixth hottest year.

The last eight years were the eight hottest and the last decade was the warmest since record-keeping began in 1880, officials from the two agencies said.

Global warming“very real. It’s now, and it’s impacting real people,” Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, told the Reuters news agency.

From intense heat in western Canada and the US, more frequent hurricanes in Atlantic, and heatwaves in southern Europe, NOAA said 2021 had “no shortage of extremes”.

Still, they said 2021 was the hottest La Nina year on record and that the year did not represent a cooling off of human-caused climate change but provided more of the same heat.

La Nina, a climate phenomenon centred in the eastern Pacific, slightly cooled global temperatures compared with what they would have been without it, scientists said.

So it’s not quite as headline-dominating as being the warmest on record, but give it another few years and we’ll see another one of those” records, said climate scientist Zeke Hausfather of the Berkeley Earth monitoring group that also ranked 2021 the sixth hottest. “It’s the long-term trend, and it’s an indomitable march upward.”

In the Artic often seen as a harbinger of broader environmental changes, maximum sea ice levels were their seventh-smallest on record, NOAA said.

Arctic sea-ice coverage has dropped by roughly 30 percent since 1980, NASA reported, and the polar region is heating about three times faster than the rest of the planet.

A key indicator of climate change, the heat content of the world’s oceans, reached a record level in 2021, the agencies said. Oceans absorb more than 90 percent of the excess heat trapped in the earth’s atmosphere by greenhouse gases and those warmer waters influence weather patterns and changes in currents.

What's scientifically interesting about that is it tells us why the planet is warming,” Schmidt said. “It’s warming because of our impacts on greenhouse gas concentrations.”

For their 2022 outlook, scientists said they expect another year of rising heat.

“There is a 10 percent change 2022 will rank first (for heat),” Russ Vose, chief analyst for NOAA’s National Centers for Environmental Information told reporters on Thursday. “And a 99 percent chance it will rank in the top 10 hottest.”

NLC To Embark On A Strike Action If....

The Nigeria Labour Congress (NLC), national president, Comrade Joe Ajaero, during the African Trade Union Alliance meeting in Abuja. Has issued a threat to embark on a nationwide strike without any notification if the pump price of fuel sells above the current price of N617. Media reports indicated an imminent increase in the price to N720. The NNPC Limited has not made any official announcement of a fuel price increment According to Ajaero, there were purported plans to further increase the pump price of petrol, which he expressed dismay that the development will cause additional and untold hardship on Nigerians. He said: “As we are here now, they are contemplating increasing the pump price of petroleum products, and the ministry of labour for some time now would only go to the Ministry of Justice to come up with a so-called injunction to hold the hands of Labour not to respond. But let me say this, Nigerian workers will not give any notice if we have not addressed the consequences of...
