...To be exact, the IPCC said, "the size of this warming (ie, the observed warming of 0.3-0.6 degrees C over the last 100 years) is broadly consistent with predictions of climate models, but it is also the same magnitude as natural climate variability. Thus, the observed increase could be largely due... | |
