The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. Thus there must be a large amount of IR absorbed by the atmosphere (around 158 W/m 2 ) – a number that would be zero in the absence of any greenhouse substances. Step 2: Trace gases contribute to the natural greenhouse effect. The Earth’s Energy Budget (NASA).

The definitive CO2/CH4 comparison post

Real Climate

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. In 2020, CO 2 was at ~410 parts per million, while CH 4 was around 1870 parts per <it>billion</it> (or 1.87 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).

Why is future sea level rise still so uncertain?

The CPDW is thought to be affected by the shift in the westerly winds around Antarctica which have increased in recent decades due to a combination of greenhouse gas forcing and the polar ozone hole ( Miller et al, 2006 ). 2020) or Sadai et al. eaaz1169, 2020.

If the SCAQMD’s development timeline holds, Proposed Rule 2305 will phase in on July 1, 2020. The Basin does not meet the state or federal ambient air quality standards for ozone and particulate matter, and existing regulations have to date proved insufficient to bring the Basin into compliance.

Reducing Your Greenhouse Gas Emissions

Greenbuilding Law

As governments enact mandatory greenhouse gas emission laws and as businesses voluntarily make “net zero” pledges, we are increasingly working with organizations, first to understand and calculate their GHG emissions, then to implement strategies for efficacious yet frictionless reductions. Organic waste sent to landfills emits CH4.
