Meanwhile, note that the factors listed above involve the whole Earth system: the oceans, the cryosphere, the atmosphere, the solid earth and lithosphere, and a full range of scales, from the city block and shoreline, to ice dynamics that change over kilometers, to GRD footprints, to the whole global ocean. 2020) or Sadai et al.
For some parts of the spectrum, the IR can be either absorbed by CO 2 or by water vapour or by clouds, but taking those overlaps into account we find that 50% of the greenhouse effect is from water vapour, 25% from clouds, and about 20% from CO 2 and the rest absorbed by ozone, aerosols, and other trace gases ( Schmidt et al, 2010 ).
In 2020, CO 2 was at ~410 parts per million, while CH 4 was around 1870 parts per <it>billion</it> (or 1.87 So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases. Historical comparisons.
“It’s [the albedo is] kept the same” [False – for instance here is a paper (Loeb et al, 2020) comparing the changes in albedo in models to the CERES observations]. It is still the case that variations in cloud feedbacks are the dominant source of variability of climate sensitivity in models (Zelinka et al, 2020).
California's summer of 2021 has seen record-breaking wildfire outbreaks, surpassing 2020 by over 500 fire events by mid-July. Over the period of 2020 and 2021, California has also experienced its two largest wildfires ever , the Dixie and August Complex fires. Levels of Ground-level Ozone Pollution Can Increase in Summer.

The decision means that NSF opts not to rebuild the telescope dish at the Arecibo Observatory, which was destroyed in late 2020. The data shows that the number of doctorates awarded in 2021 dropped by 5.4%% from 2020 levels, the biggest decrease recorded since NSF started tracking this information in 1958.

In 2015, when he took office as AG after stints in the Texas Legislature, he sued the Environmental Protection Agency for strengthening a standard for ground-level ozone, better known as smog. Hurricanes or no hurricanes, Mississippi AG Lynn Fitch, who took office in January 2020, takes a dim view of federal action on climate change.
In an unpublished judgment, the court rejected the petitioners’ other NEPA arguments regarding project design and capacity and cumulative ozone impacts. CDV-2020-307 (Mont.

Legislators provide $200 million to NOAA for weather, coasts, oceans and climate research, $100 million for NOAA competitive climate research grants and provides $100 million to NOAA for development and dissemination of climate science information products and services.

EPA of a 2015 rule barring replacement of ozone-depleting substances with hydrofluorocarbons (HFCs), which are powerful greenhouse gases. Circuit vacated the 2015 rule to the extent that it prohibited continued use of HFCs by companies that previously switched to HFCs from an ozone-depleting substance. May 1, 2020).
Endangered Species : The US Fish and Wildlife Service agreed to reconsider Endangered Species Act protections for the Clear Lake hitch, a freshwater minnow found in California, after environmental groups challenged the agency’s 2020 decision not to list the species.

For example, recent attention has focused on tightening the National Ambient Air Quality Standards (NAAQS) for ozone smog, which is formed by atmospheric reactions on volatile organic compounds (VOCs) and nitrogen oxides (NOx). The SCC then monetizes those impacts over time.
