This is certainly true:
The truth is that there are no facts that link the concentration of atmospheric carbon dioxide with imminent catastrophic global warming.
The IPCC, which is, after all, the scientific consensus, also says the same. The important qualifiers are "imminent" and "catastrophic".
What is actually being said is that the world will, in 100 years (as far as things go in any detail) will not be as good as it could be unless something is done.
