A major principle of the enviro movement is the Precautionary Principle, which is that if there is a chance of a change in policy causing harm, you should not make that change until you have proven the harm won’t occur.

anyone quoting the IPCC as gospel truth and being without an agenda is not to be trusted nor believed.
