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. 2015) , and this is also applies to Kininmonth’s calculations.

The Atlantic meridional overturning circulation (AMOC) is a large-scale overturning motion of the entire Atlantic, from the Southern Ocean to the high north. Graph by Ruijian Gou. The AMOC is a big deal for climate. It moves around 15 million cubic meters of water per second (i.e. 15 Sverdrup). For more on this see my Review Paper in Nature.

It is 33 years now since the IPCC in its first report in 1990 concluded that it is “certain” that greenhouse gas emissions from human activities “will enhance the greenhouse effect, resulting on average in an additional warming of the Earth’s surface.” Gray areas show lack of data.

Two reports published in the US look seriously at the practicalities and responsibilities of altering the ocean to tackle the climate crisis. Two recent developments aim to clear a path for testing these controversial methods in the ocean. The ocean as a carbon sink. Photo credit: Daniel Poloha / Alamy. By Olive Heffernan.

However, that was written in 2007 – 15 years ago! 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. The Earth’s Energy Budget (NASA).

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 ). Furthermore, the volume of the oceans increases from the melting of land ice. See for instance Benestad (2016).

Unlike in years past, there is no longer any serious discrepancy between the records – which use multiple approaches for the ocean temperatures, the homogenization of the weather stations records, and interpolation. Southern Ocean trends. The least visited part of the ocean are the waters around Antarctica. References.
