2025 RationalWiki 'Oregon Plan' Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff—we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

Fighting pseudoscience isn't free.
We are 100% user-supported! Help and donate $5, $10, $20 or whatever you can today with PayPal Logo.png!

Question on runaway methane[edit]

It's my understanding that we've been in non-ice ages before. Wouldn't that have resulted in the permafrost disappearing and the methane being released as well? A feedback effect would've happened before, yet Earth didn't turn into Venus then. To me, it's scaremongering when it isn't even needed. "Weather patterns shift and the sea level rises, massive crop failures everywhere, horrible wars as Europe and the US invade Canada and Russia for farmland" is already pretty damn scary.
