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 ”.

However, that was written in 2007 – 15 years ago! This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). The only question is how much total energy is blocked by each.

The energy balance of our planet , the radiation arriving and leaving, is continually monitored by a global radiation network at the surface and by dedicated satellites. And yes, also the increase in back-radiation towards the Earth surface from the CO2 greenhouse effect is a measured fact.

First observed in 2007, FRBs are short, intense pulses of radio waves of unknown origin. However, since 2007 hundreds of FRBs have been observed, allowing astrophysicists to develop models that predict that FRBs come from magnetars – which are neutron stars that have extremely strong magnetic fields.

One school of thought holds that information does escape from black holes in the form of photons emitted via a process known as Hawking radiation. In 2007, while investigating this paradox, physicists Patrick Hayden and John Preskill came up with a thought experiment. Courtesy: Zoe Holmes). Scramblers beset by barren plateaus.

In other words, the claim shows a lack of knowledge and is a well-known old argument that I commented on Realclimate.org in 2007. In 2013, there was a report in the Guardian about scientific studies that refuted the opinion that solar activity or cosmic radiation should explain climate change. See for instance Benestad (2016).
