“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 …

Climate Emergency: Time to Slam on the Brakes

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 …

A basic overview of melting ice around the globe

I wrote this post for Skeptical Science as a basic rebuttal of the argument “Ice isn’t melting”. Contrary to contrarian claims, ice is melting at accelerating rates in the Arctic, Antarctica, Greenland, and glaciers all over the world. Arctic sea ice has shrunk by an area equal to Western Australia, and could be all gone …

Increasing southern sea ice

This post was written for Skeptical Science as a “basic rebuttal” to the argument “Southern sea ice is increasing”. Sea ice around Antarctica has increased over the few decades that satellites have been measuring sea ice extent. First of all, it’s worth remembering that sea ice is not to be confused with land ice. This …

Global Warming Contrarians Part 3: Hiding the Decline of Ice

In 2007, the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC) concluded that global warming is unequivocal, and that serious impacts of global warming are already beginning to occur. The AR5 isn’t due until 2013, but in 2009, a non-IPCC report called the Copenhagen Diagnosis was released to provide an update …
