Cold deaths vastly outweigh heat deaths. This is common knowledge in the academic literature and for instance the Lancet finds that each year, almost 600,000 people die globally from heat but 4.5 million from cold. As temperatures rise, heat deaths increase, but cold deaths decrease more than twice as much. We are seeing 166,000 fewer temperature-related deaths each year by 2018 compared to the year 2000. Extrapolating to 2024, there are 300,000 fewer annual temperature-related deaths compared to the year 2000. Bjorn Lomborg wrote "A group of campaign researchers try hilariously, ineptly — and depressingly —to suppress facts." The group Climate Feedback fabricated an absurd quote, which is contradicted in the very article they claim to 'fact-check'.

In 2020, fuel regulations abruptly reduced the emission of sulfur dioxide from international shipping by about 80% and created an inadvertent geoengineering termination shock with global impact. On January 1, 2020, new international regulations on the sulfur content of shipping fuel reduced the maximum sulfur content from 3.5% to 0.5%. Ship-emitted aerosols and sulfur dioxide, which creates atmospheric aerosols, caused linear trails of brighter oceanic clouds. The reduction of marine aerosols reduces the cloud cover, allowing more sunlight in to warm the ocean surface.This paper estimates the regulation leads to a radiative forcing of 0.2 Wm−2 averaged over the global ocean. The amount of radiative forcing could lead to a doubling (or more) of the warming rate in the 2020 s compared with the rate since 1980. The regulation change will make the 2020 s anomalously warm.

The amount of water vapor injected into the stratosphere (SWV) after the eruption of Hunga Tonga-Hunga Ha'apai (HTHH) was unprecedented. This new paper evaluated the surface temperature and precipitation impacts of the HTHH water vapour perturbation using a chemistry climate model simulation. The paper’s abstract says “The simulations show that the SWV anomalies lead to strong and persistent warming of Northern Hemisphere landmasses in boreal winter, and austral winter cooling over Australia, years after eruption, demonstrating that large SWV forcing can have surface impacts on a decadal timescale. Surface temperatures across large regions of Northern Hemisphere increase by over 1.5 °C for several years
