This makes several assumptions.
...changes in the sun’s radiation can’t account for the increase in temperatures we’ve seen over the past decades.
The notion is impossible to defend scientifically.
So is your assertion that the sun's radiation is a non-factor. It is a factor, how large? Still being determined.
The IPCC report was produced by the unanimous agreement of every country signed up to the United Nations Framework Convention on Climate Change. That’s a lot of countries [197, to be precise].
Oh good. Science has never been about consensus. Science is about truth. Until a scientific discovery is made, the consensus is it doesn't exist. The consensus was once that the earth was flat. The consensus was once that electricity in the form of lighting bolts came from angry gods and electricity itself was an unknown. The consensus was once that nuclear power was non-existent. The consensus was once that viruses and bacteria didn't exist and that disease and sickness were from angry gods. Etc. etc. Consensus is never, NEVER a valid defense of a position.
So there’s very strong unanimity, which makes it difficult to accuse the IPCC of saying anything incorrect.
SMH - mafia tactics.
So it’s quite clear from the evidence we’re seeing today that the adaptation of species is not happening.
Wow, hundreds of millions of years of evolution have suddenly stopped in their tracks? I'd say we have a far larger issue than what the temperature is going to be tomorrow. When someone makes absurd assertions such as this it is impossible to take them seriously on any issue.
