Cut Emissions, Increase 'Warming'?

So many factors, some of which are hardly yet known, affect the rise and fall of planetary temperatures that it is certainly possible that tinkering on one end has the opposite of the intended effect. Watts Up With That points to one example possibly attributable to something called IMO 2020, which has severely reduced sulphur emissions from shipping fuel starting in 2020:

The world of climate science is in shock following extraordinary findings from a team of high-powered NASA scientists that suggest most of the recent global temperature increases are due to the introduction of draconian fuel shipping regulations designed to help prevent global warming. The fantasy world of Net Zero is of course full of unintended consequences, but it is claimed that the abrupt 80% cut in sulphur dioxide emissions from international shipping in 2020 has accounted for 80% of global warming since the turn of the decade.

The news is likely to cause considerable concern among the mainstream climate hoaxers in media, academia and politics. They have had a field day of late by pointing to rises in temperature as evidence for their evidence-free prediction that the climate is in danger of imminent collapse... The science behind the NASA findings, which have been published in Nature, is simple. Fewer fuel particles injected into the atmosphere reduce cloud droplet density and this leads to clouds that reflect less solar radiation back into space.

In the words of the NASA scientists who observed the ironic effect:

While IMO 2020 is intended to benefit public health by decreasing aerosol loading, this decrease in aerosols can temporarily accelerate global warming by dimming clouds across the global oceans. IMO 2020 took effect in a short period of time and likely has global impact... Observations of ship-tracks suggest that... a regulation intended to reduce pollution had collateral effects on cloud microphysics.

Of course, the hoaxers aren't going to take this lying down:

Climate activists at the Potsdam Institute for Climate Impact say the observation period is too short, and man-made greenhouse gases continue to play the decisive role in climate change... [Still] the IPCC promotes the view that almost all climate change since around 1900 is caused by the activities of humans. This unproven opinion looks shakier by the day.

What’s not scientific is claiming anything about the climate is "settled" and that panicked, draconian measures have to be instituted immediately or else we're all doomed.
