New misguided interpretations of the greenhouse effect from William Kininmonth

Real Climate

Another clue is William Kininmonth’s ‘rethink’ on the greenhouse effect for The Global Warming Policy Foundation. When looking at the effect of changes in greenhouse gases, one must look at how their forcing corresponds to the energy balance at the top of the atmosphere. 679-688, 2016. 679-688, 2016.

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.

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. Before we go any further though, we need to understand that the effective perturbation time for CO 2 and CH 4 in the atmosphere are very different. Historical comparisons.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

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 ). See for instance Benestad (2016). I don’t know the answer to his question.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

The Global Methane Pledge

Legal Planet

22 degrees by 2050 because of both the reduced emissions and the dissipation of methane in the atmosphere, potentially allowing the world a bit more time to reduce and sequester other greenhouse gases. A worldwide methane emission reduction of 30 percent by 2030 could reduce global warming by.22

Should the official Atlantic hurricane season be lengthened?

Real Climate

But this also raises other questions: 1) Can we expect the season to continue to lengthen as global warming from increasing concentration of globally well mixed greenhouse gas (GWM-GHG) continues to warm the Atlantic SSTs? In particular, they don’t just respond to SST changes, but also how the atmosphere changes as the SSTs change.
