New Research Says Doubling CO2 Leads To A ‘Sometimes’ Negative Greenhouse Effect
By Kenneth Richard on 15. January 2024
“Negative TOA [top of atmosphere] forcing of CO2 increase also happens outside of Antarctica. The Arctic sometimes exhibits strong negative CO2 forcing. This phenomenon even occurs in the tropics and mid-latitudes…” – Chen et al., 2024
It has previously been reported that as CO2 increases from 380 ppm to 1000 ppm, the CO2 greenhouse effect is negative (-2.9 W/m²) over Antarctica, or that CO2 “increases radiative cooling” there (Schmithüsen et al., 2015).
Also, the CO2 greenhouse effect is as “comparatively weak” (hovering around 0 W/m²) over Greenland as it is over Antarctica, but it is not negative there, as it is “invariably” above 0 W/m² in the Arctic. In other words, there is no such thing as a CO2-enhanced “polar amplification” at locations where it is commonly claimed CO2 is causing catastrophic ice melt.
