Global monthly mean atmospheric carbon dioxide, 1979-2022. The global surface average for CO2 rose by 2.13 parts per million (ppm) to 417.06 ppm, roughly the same rate observed during the last decade. Atmospheric CO2 is now 50% higher than pre-industrial levels. 2022 was the 11th consecutive year CO2 increased by more than 2 ppm, the highest sustained rate of CO2 increases in the 65 years since monitoring began. Prior to 2013, three consecutive years of CO2 growth of 2 ppm or more had never been recorded. The Global Monitoring Division of NOAA/Earth System Research Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites. This graph shows monthly mean abundance of carbon dioxide globally averaged over marine surface sites. Graphic: NOAA Global Monitoring Laboratory

Greenhouse gases continued to increase rapidly in 2022 – Carbon dioxide, methane, and nitrous oxide rise further into uncharted levels – “Greenhouse gas emissions continue to rise at an alarming pace and will persist in the atmosphere for thousands of years”

5 April 2023 (NOAA) – Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists.  The global surface average for CO2 rose by 2.13 […]

A long-dormant lake has reappeared in California, bringing havoc along with it – “This impending monster – a 50-foot-plus deep snowpack that we haven’t seen in 75 years – is sitting up there, and we just don’t know how fast it’s going to turn into water and come out of the mountains”

By Evan Bush 2 April 2023 (NBC News) – People have worked for a century to make California’s Tulare Basin into a food grower’s paradise. That pastoral landscape now looks more like the Pacific Ocean in many areas. Months of atmospheric river storms have pummeled the area and saturated the basin’s soil, which sits about […]

Gulf of Mexico oil worse for climate than thought, study – “Expanding production in shallow waters, the way it’s been done historically, would have disproportionately high climate impacts”

By Drew Costley 3 April 2023 (AP) – Offshore oil and gas operations in the Gulf of Mexico are releasing far more climate-changing methane than official estimates show, according to a new study published Monday. Using data collected from aircraft in part, climate scientists found the additional methane coming from oil and gas platforms in the Gulf […]
