April 14, 2021 Levels of atmospheric carbon dioxide (CO2) and methane continued to rise in 2020, said NOAA, despite the economic slowdown caused by the coronavirus pandemic response. Levels of climate-warming carbon dioxide (CO2) and methane in the atmosphere continued to rise in 2020, with CO2 levels reaching their highest point in 3.6 million years, according to NOAA research, despite the economic slowdown caused by the coronavirus pandemic response. According to the NOAA report, released April 7, 2021, the global average for CO2 in the atmosphere in 2020 was 412.5 parts per million (ppm) i...

Carbon dioxide levels saw a surge in 2020 to the highest since the mid-Pliocene era 3.6 million years ago. During this prehistoric time period, sea level was about 78 feet higher and the Earth's temperature was about 7 degrees Fahrenheit warmer than our modern-day world. The year-over-year rise in CO2, 2.6 parts per million, is one of the highest recorded since NOAA started tracking more than 60 years ago.  The agency didn't offer an explanation for the increase, but its possible the effect was cumulative.  In addition, electricity usage in the residential sector actually increased during ...

8 April 2021 Scientists have recorded a surprising rise in atmospheric carbon dioxide and methane levels over 2020, seeming to contradict predictions that the pandemic would see a temporary slowdown in the build up of greenhouse gases in the atmosphere. Research by United States government agency the National Oceanic and Atmospheric Administration (NOAA) found average surface level atmospheric CO 2 levels hit an all-time high of 412.5 parts per million (ppm), up 2.6 ppm on 2019 levels. That was the fifth highest increase on record, after 1987, 1998, 2015 and 2016. Atmospheric CO2 levels are n...

8 APRIL 2021 Even after a year of coronavirus lockdowns and shutdowns, global emissions of greenhouse gases are still increasing at an unrelenting rate.  Today, according to initial measurements from the National Oceanic and Atmospheric Administration (NOAA), global levels of carbon dioxide emissions are higher than they have been at any given time in the past 3.6 million years. Annual methane emissions - a greenhouse gas 28 times more potent than CO 2 - just experienced their largest year-on-year increase since records began in 1983.   These disappointing numbers were calculated from va...

© istock Carbon dioxide and methane emissions surged in 2020 even amid coronavirus shutdowns, according to research from the National Oceanic and Atmospheric Administration (NOAA) released Wednesday. Data collected at remote NOAA sampling locations indicated the global surface average for CO2 was 412.5 parts per million last year, a 2.6 ppm increase. The global increase rate constituted the fifth-highest on record for a single year, after 1987, 1998, 2015 and 2016, according to NOAA.  “Human activity is driving climate change,” said Colm Sweeney, assistant deputy director of the Glob...
