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 Latest IPCC Report — How Are We Doing on Mitigation?

Law and Environment

Nonetheless, here are some of what seemed to me to be important takeaways: Firstly, and most importantly, we’re not doing a very good job at mitigating greenhouse gas emissions. I suspect that, if one asked the average American whether GHG emissions increased or decreased from 2010 to 2019, they would say that emissions decreased.

Net Zero/Not Zero

Real Climate

Net-zero greenhouse gas emission does not have any geophysical significance. Wherever the authors had made a reference to net-zero CO2 emissions, the Saudis (and sometimes China) tried to amend it to say net-zero greenhouse gases instead. coming as part of the upgrade to Nationally Determined Contributions (NDCs) for the COP26 meeting.
