Scientists say one of the most rapid periods of warming in Earth’s history was due to gradual release of CO2, warning current levels of emissions were even higher

August 30, 2017 — A dramatic period of global warming 56 million years ago that saw temperatures climb by up to five degrees and triggered extinctions of marine organisms was down to volcanic Continue reading Volcanic eruptions triggered global warming 56m years ago, study reveals

There are parallels between today’s and past greenhouse gas-driven climate changes

August 1, 2017 — Coincidence doesn’t prove causality, as they say, but when the same two things happen together over and over again through the vast span of geological time, there must be a causal link.

Humans are disgorging heat-trapping carbon into the atmosphere 10 times faster than during any period of natural global warming in the last 66 million years

PARIS, France (Mar. 22, 2016) — Humans are disgorging heat-trapping carbon into the atmosphere 10 times faster than during any period of natural global warming in the last 66 million years, according to a study released Monday, March 21.
