Gavin Schmidt Welcomes Scientific Studies Attempting To Explain The Great Global Warming Acceleration Of 2023/24

The Era of Global Boiling came upon us very suddenly and unexpectedly starting in early summer 2023. NASA Goddard Institute scientist Gavin Schmidt wants to know why and welcomes all research which attempts to solve the puzzle. On the face of it, this is good. This is how science is supposed to work:

‘Houston, we have a problem.’

‘OK, let’s solve it.’

Zeke Hausfather tweeted on X:

All sounds pretty open to me; an invitation to a proper scientific debate on the possible causes of an observed phenomenon which is unexplained and was not predicted by the existing science. Hunga Tonga even gets a mention! I’m a little sceptical as to the outcome though. Why? Because Hausfather also tweeted this:

The WAPO article reads thus:

It is widely accepted that humans have been heating up the planet for over a century by burning coal, oil and gas. Earth has already warmed by almost 1.2 degrees Celsius (2.2 degrees Fahrenheit) since preindustrial times, and the planet is poised to race past the hoped-for limit of 1.5 degrees Celsius of warming.

But fewer people know that burning fossil fuels doesn’t just cause global warming — it also causes global cooling. It is one of the great ironies of climate change that air pollution, which has killed tens of millions, has also curbed some of the worst effects of a warming planet.

Tiny particles from the combustion of coal, oil and gas can reflect sunlight and spur the formation of clouds, shading the planet from the sun’s rays. Since the 1980s, those particles have offset between 40 and 80 percent of the warming caused by greenhouse gases.

And now, as society cleans up pollution, that cooling effect is waning. New regulations have cut the amount of sulfur aerosols from global shipping traffic across the oceans; China, fighting its own air pollution problem, has slashed sulfur pollution dramatically in the last decade.

“We’re starting from an area of deep, deep uncertainty,” said Zeke Hausfather, a climate scientist and research lead for the payments company Stripe. “It could be a full degree of cooling being masked.”

Over the past few decades, countries have worked to phase out these pollutants, starting with the United States and the European Union, followed by China and India. China has cut its sulfur dioxide emissions by over 70 percent since 2005 by installing new technologies and scrubbers on fossil fuel plants. More recently, the International Maritime Organization instituted restrictions in 2020 on the amount of sulfur allowed in shipping fuels — one of the dirtiest fuels used in transportation. Shipping emissions of sulfur dioxide immediately dropped by about 80 percent. Mediterranean countries are planning a similar shipping regulation for 2025.

Much to unpack here. Firstly, why does Stripe (the company which Substack uses by default to accept payments from subscribers) employ a climate scientist as a ‘research lead’? Moreover, a climate scientist steeped in the ethos of man-made global warming who believes that all global warming since the beginning of the Industrial era is caused by human beings, essentially denying any role for natural climate variability. I don’t get it. What have online payments processing got to do with climate change? Why is a finance company employing a climate scientist? Recall that Robert Malone recently had to threaten Stripe with legal action because they were going to close his account down if he didn’t disclose personal financial details to them. Other Substack authors have received similar demands. Doesn’t exactly inspire confidence in Stripe does it, or ‘free speech’ Substack for that matter, with whom they partner. All rather odd.

But back to the science. They’re talking aerosols and shipping emissions again, despite the fact that Zeke himself critiqued a recent paper blaming 2023 warmth for the IMO2020 sulphur regulations and stated:

While these values are not trivial, and certainly contributed to record warmth in 2023, its hard to explain more than 0.1C of the global mean temperature increase experienced to-date from the IMO regulations across the range of transient climate responses found in CMIP6 models. It remains a part of the explanation for the weirdness we experienced in the latter half of last year, but far from the full one.

I wrote about that paper here:

Zeke’s Substack article is here:

A problematic estimate of warming from low-sulfur marine fuels

Now Zeke’s telling us that, on the contrary, the sum total of all anthropogenic aerosol forcings over the years could have masked as much as 1C of anthropogenic GHG warming!

I’ve said it before: anthropogenic aerosol cooling is the flip side of the greenhouse gas global warming coin. They need aerosols to explain the observed lack of historic warming from the vastly overheated climate models, plus the occurrence of the inconvenient mid 20th century cooling. During the 1960s/70s global cooling period, scientists were preparing to blame aerosols from the burning of fossil fuels for the scary advent of a new ice age! It was only after the 1976 Great pacific Climate Shift, when the world started warming rapidly again, that they switched to blaming carbon dioxide for climate change instead. Total scam.

So I’m wondering whether Gavin Schmidt’s AGU invitation for research submissions to explain the anomalous 2023/24 warmth will eventually end up with the conclusion that it was the combination of the ongoing emissions of anthropogenic greenhouse gases and the continuing decline of anthropogenic aerosols wot dunnit. No room for natural climate change/weather phenomena whatsoever. Science!
