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) in 2020, rising by 2.6 ppm during the year. It said CO 2 concentrations will exceed 417 ppm at some point between April and June—50 percent higher than the 278 ppm present in the late 18th century when the industrial era kicked off. This is The record of 421 parts per million reached Saturday is just a single point and occurred as CO2 levels are nearing their yearly peak. But the levels over the past two months, of more than 417 parts The new forecast by the UK Met Office says that the concentrations of CO 2 will be around 2.29 parts per million (ppm) higher in 2021 than in 2020 at the Mauna Loa Observatory in Hawaii. Carbon Dioxide Levels and Your Health 250 – 350 ppm + background (normal) outdoor air level 350- 1,000 ppm – typical level found in occupied spaces with good air exchange.

Last Updated: April 10, 2021. Hourly (red circles) and Daily (yellow circles) averaged CO 2 values from Mauna Loa, Hawaii for the last 31 days. The graph, updated daily, shows as individual points daily and hourly mean CO 2 for the last 31 days. Se hela listan på climate.gov Stabilize CO2.

I första spalten kan vi läsa: We ﬁnd that the average gradients of fossil fuel CO2 in the lower 1200m of the atmosphere are close to 15 ppm at a 12 km×12 km horizontal resolution. Här står “15 ppm”, vilket är vad som sedan spritts. Emellertid är det en ”gradient”. Ned, "if CO2 were to go over 2000 ppm today most of that ice would (eventually) be gone." Agreed. And I certainly am not questioning the role of solar irradiance. But the geological proof that ice once existed at our South Pole -- striated bedrock among other unmistakable features -- would still be there.
