And, for example, these are not conflicting points:
The IPCCs Feb. 2007 report stated: It is very likely that human activity is causing global warming. Why then, just two months later, did the Vice Chair of the IPCC, Yuri Izrael, write, the panic over global warming is totally unjustified; there is no serious threat to the climate; and humanity is hypothetically more threatened by cold than by global warming?
Define “very likely”.
