The CERES estimates of the top-of-atmosphere radiative fluxes are available from 2001 to the present. 2021) also reported on a two decade estimate of Earthshine measurements which appear to confirm a small decrease in albedo (and decrease in reflected short wave (SW) radiation). A paper last year (Goode et al., It’s unlikely(?)

In that year, El Nio added to the increased warming caused by the build-up of heat-trapping emissions in the atmosphere, leading to that record-breaking heat. Albedo is the total reflection of incoming solar radiation by Earth. This question was a focus at the 2024 annual American Geophysical Union (AGU) meeting in Washington, D.C.,

But methane’s role in atmospheric chemistry and as a source of stratospheric water vapour means that it has a bigger effect on climate than just the direct effect of its concentration. Before we go any further though, we need to understand that the effective perturbation time for CO 2 and CH 4 in the atmosphere are very different.

He made some rather strange claims, such as that the Intergovernmental Panel on Climate Change (IPCC) allegedly should have forgotten that the earth is a sphere because “ most absorption of solar radiation takes place over the tropics, while there is excess emission of longwave radiation to space over higher latitudes ”.

So SSU me Like MSU trends, these records reflected a weighted average of atmospheric temperatures, and the three SSU channels progressively weight higher levels in the stratosphere, roughly centered on 30km, 40km and 45km above the surface but with quite a bit of overlap. The effect is larger the further up you go. References B.D. Casas, G.A.

Tiny particles of plastic in the atmosphere can affect Earth’s climate, according to Laura Revell at the University of Canterbury in New Zealand and colleagues. Yet even as airborne microplastics become an ever-larger part of the mix of atmospheric aerosols, their radiative influence is still virtually unknown. Altitude matters.

As space missions venture ever further afield, spacecraft will inevitably be exposed to greater amounts of cosmic radiation that can damage or even destroy their onboard electronics. Cosmic radiation is ionizing radiation made up of a mixture of heavy ions and cosmic rays (high-energy protons, electron and atomic nuclei).
