It is a theory that could be correct. Then again the theory that life was seeded here from aliens could be correct too. The good science that supports AGW is sorely lacking.
There is no scientific theory that life was seeded here from aliens. There is some speculation, that's all.
Surely, you understand the difference between a scientific theory simple speculation!
The CERN study did EXACTLY that. It provided new evidence in support of an alternative theory. The theory that earth's warming is due to the sun is a better theory than AGW. Though the theory that the warming and cooling we see is just cyclic is just as sound, especially since we do not even have any measurements at all that measure the temperature of the area in and around the Earth.
The CERN study questioned how much warming is due to human activities.
It could be true that there is no warming.
It might be true that there is warming but it is due entirely to the sun and not at all due to CO2. We should get the politics out of the debate, e.g IPCC, NASA.
It is equally likely to be true that the germ theory of disease is wrong. But, yes, absolutely, we should get politics out of the debate.
If you don't like the scientific organizations that are supported by the various governments, listen to the ones that are supported privately.
But what is certain is that many of the players are biased at best and dishonest at worst.
The "players" are not biased and dishonest. The pundits and commentators are biased and dishonest.
But, it does not matter. There is no way we're going to reverse the process anyway. There is also no way that true believers are going to change their belief systems, regardless of scientific findings. If living in the 21st. century doesn't convince anyone that the scientific method is superior to simply deciding on what you want to believe, then nothing will
So, nothing will.
