“Over the bleached bones and jumbled residues of numerous civilizations are written the pathetic words: ‘Too late.’” – Martin Luther King Jr. I’ve been reading up on what the latest climate science says about where we are and where we’re heading, and decided the best way to present the information is in the following table. …

Is Greenland close to a climate tipping point?

Recent findings suggest climate change in Greenland may be approaching a tipping point, beyond which amplifying feedbacks could lead (probably over centuries) to complete melting of the ice sheet, raising sea level by about 7 meters. In June, a team of glaciologists led by Jason Box predicted that we would see melting across 100% of …

I wrote this post for Skeptical Science as a basic rebuttal of the argument “It’s not urgent”. Global warming is an increasingly urgent problem. The urgency isn’t obvious because a large amount of warming is being delayed. But some of the latest research says if we want to keep the Earth’s climate within the range …

Global Warming Contrarians Part 4: Back to Basics

So far in my series of posts on the arguments contrarians make against global warming, I’ve written about the changes being observed in the Earth’s climate. I wrote about whether the global temperature has increased (short answer: yes); whether it has recently stopped increasing (short answer: probably not); and whether ice is declining around the …
