It’s an interesting time, where multiple events coincide. The most important are the ones the so called “Climate Scientists” sweep under the carpet.

Undoubtedly the most important is the approx equivalent of 60000 Olympic size swimming pools of water that the Tonga volcano ejected into the stratosphere.

Secondary to this is the developing El Niño and the fact that the Atlantic Ocean multi-decadal oscillation is approaching it’s maximum. There is also the reduced cloud cover over the oceans, especially the North Atlantic, possibly since the introduction of low sulphur fuels which reduced cloud condensation nuclei, resulting in increased solar insolation.

One other important point is how the policy of Net Zero, where outlawing the burning of fossil fuels is reduce important cloud condensation nuclei, reducing cloud cover, increasing temperatures. Global warming then becomes a self fulfilling prophecy.

I too would tend towards natural variability, however it’s a complex area with very little data. Having spent several years cloud seeding on the edge of the ITCZ over river catchments, while seeing firsthand clouds rapidly develop and precipitate after seeding, while others simply evaporate and collapse just as quickly. Making it one of my favourite areas of interest, especially with regard to hygroscopic Nuclei.

Natures hygroscopic CCN’s, mainly provided by salt from sea spray. Volcanic ash. Smoke from forest and scrub fires with lightning being the ignition source. Dust and sand being lifted by the wind. Then there are cosmic rays etc, an topic outside my area.

The big questions.

As the earth matured, is there less volcanic ash.

As we try and prevent fires, are we reducing smoke.

To what extend has urbanisation, changes in farming and land use reduced the availability of dust. Has the burning of fossil fuels added to, or replaced possibly

falling natural smoke.

Whoever said the science is settled with regard to climate change, was pulling a fast one.
