The next week has the potential to bring important developments for international governance of marine carbon dioxide removal (CDR). seaweed) for carbon storage. Solar radiation management is distinct from CDR. to 2 o C in line with the goals of the Paris Agreement.

Attribution Science and EPA’s Reconsideration of the GHG Endangerment Finding

Law Columbia

On March 12, Environmental Protection Agency (EPA) Administrator Lee Zeldin announced plans to reconsider EPAs 2009 endangerment finding for greenhouse gas (GHG) emissions, along with all regulations and actions that rely on the finding. The Supreme Court explicitly held in Massachusetts v. cars endanger public welfare.

The enigma of Trappist-1 b: a thick atmosphere or airless rock?

Physics World

and 15 µm), suggest that the exoplanet could either be bare, airless rock like Mercury or shrouded by a hazy carbon dioxide (CO 2 ) atmosphere like Titan. For an atmosphere dominated by greenhouse gases such as CO 2, which is strongly absorbing, temperature is expected to increase with increasing pressure (at lower levels).

Can Life Survive the Death of the Sun?

Scientific American

The difference exists because greenhouse gases in the air essentially trap heat from the sun, warming Earth above the calculated temperature. At the same time its surface temperature will drop, so it becomes ruddier, even as it radiates energy 2,400 times stronger than it does now. This transforms the sun into a red giant star.

The definitive CO2/CH4 comparison post

Real Climate

, but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane. 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.

The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.
