US delegates tried to water down the latest IPCC report:
US delegates in particular said references to “irreversible” climate change and impacts were imprecise.
They argued, for example, that the melting of glaciers or ice sheets — which could raise ocean levels by several meters (a dozen feet) — was not “irreversible” as ice could eventually reform.
And also the loss of species was not irreversible because new ones would evolve in a few million years.
And instead of saying that half of all species becoming extinct, the report should say that half of all species will be “just fine”.
