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 …

Christy Crock: Do the observations match the models?

I wrote this post for Skeptical Science. At the recent US House of Representatives Committee on Science Space and Technology climate hearing, the Republicans called Dr. John Christy as an expert witness testifying against the global warming consensus. Unfortunately, Christy spent his time repeating a long list of climate myths, including the common contrarian refrain …

Zero Carbon Australia: We can do it

I wrote this post for Skeptical Science. My recent post about long-term CO2 targets was rather doom-and-gloom: I concluded that we must phase out fossil fuels to keep the climate in the range that humans have experienced. The good news is that action on this scale is not only possible but surprisingly feasible. Last year, …

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 …

2010: A Year of Record Warmth and Weird Weather

Last year’s global temperatures are in, and the result is that 2010 is statistically tied with 2005 for the title of the warmest year since records began in 1880. According to the US National Oceanic and Atmospheric Administration’s National Climatic Data Center (NOAA NCDC), the global temperature for both years was 0.62°C above the 20th-century …

Monckton Myth: Global Sea Ice

I wrote this post for Skeptical Science as part of an ongoing series looking at the arguments made by Christopher Monckton against climate science. This post examines Monckton’s arguments about global sea ice. Monckton claims: [T]he global sea ice record shows virtually no change throughout the past 30 years, because the quite rapid loss of …

Scientific Guide to Global Warming Skepticism

The Skeptical Science team (which includes myself) have recently completed a 16-page booklet called The Scientific Guide to Global Warming Skepticism. (Actually it was completed a fortnight ago, but I forgot to link to it at the time. Anyway, better late than never.) To quote John Cook’s blog post launching the Guide: Scientific skepticism is …

The Fake Scandal of Climategate

This post was written for Skeptical Science as the first part of a series on the fake scandal of Climategate. It’s bad enough that global warming contrarians are successfully misleading the public by propagating misconceptions about climate science. But recently it has become popular to attack climate scientists themselves, to accuse them of fraud and …

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 …
