Ongoing paleo study may help tune CO2 climate sensitivity

Here on Bitsofscience.org we’ve discussed the Paleocene-Eocene Thermal Maximum (PETM) – that sudden CO2 and methane-induced peak climate warming (or ‘hyperthermal’) 55.8 million years ago of around 6 degrees over 20,000 years – on several occasions, because it offers an … Continue reading →

Current CO2 rise 10 times as fast as PETM climate disaster

For the layman paleoclimatology is ‘proof’ that any climate change is natural. For educated thinkers the lessons from the long ago contain the biggest warnings for the current artificially created state of our planet.

No evidence bacteria ate methane at end of Snowball Earth

Same story as yesterday, but now 635 million years earlier. This time again no evidence can be found that it were microbes that ate climate-disrupting amounts of methane, at the end of the Marinoan ice age, better known as ‘Snowball … Continue reading →
