2013 Greenhouse Radiation

Delayed action on emissions cuts may require even more (and more expensive) CDR – the 2024 United Nations Emissions Gap Report released this week found that 2023 greenhouse gas emissions set a new record, and current emissions reduction pledges for 2030 are insufficient to meet temperature goals.

The radiative forcing bar chart has gone full circle: Almost every IPCC report has a version of the radiative bar chart showing the contributions over the historical period of all the different forcings (greenhouse gases, aerosols, solar, etc.). Oddly enough this is most reminiscent of the very first bar chart that appeared in Hansen et al.

A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). I don’t know the answer to his question. But this discussion paper is problematic for sure.

And since the first IPCC estimates published in 2013, we have learned a lot and have gotten much better at estimating remaining carbon budgets. IPCC reported carbon budgets for the first time in 2013. in 2018, but they represent a significant update since AR5 in 2013. In the 2018 IPCC Special Report on Global Warming of 1.5°C

On their own, our greenhouse gas emissions would have caused a much higher warming, were it not for the masking effect of aerosol pollution. warmer than pre-industrial times (here defined as 1850-1900). Obviously, this goes most of the way to 1.5? of warming and human influence is pretty much the sole contributor to this observed warming.

The first, known as greenhouse gas (GHG) removal , seeks to mitigate climate change by pulling GHGs – most commonly carbon dioxide – out of the atmosphere and durably storing them. The second category of marine geoengineering activities, known as solar radiation management or modification (SRM), do not directly target GHGs.

We breathe oxygen from the atmosphere, weather systems distribute water, and the ozone in the upper atmosphere protects us from harmful radiation. One of the most well-known ways we have impacted our atmosphere is through the emission of greenhouse gases, which have adversely affected our climate. 47 1002210031 (2013). [7]
