Global warming projections from 1981 prove tellingly accurate

A seminal article by climate scientists back in 1981 has proved eerily accurate at predicting global temperature rises over the last three decades, with its lead author James Hansen telling Crikey that his early research on global warming "seems to hold up remarkably well".

It’s getting hot in here

It’s getting hot in here

A baby Koel bird sat in my garden yesterday afternoon screaming in distress at the extreme heat wave. It sat there in the 41-degree weather, confused and making repetitive loud noises. All I could do was put water in the garden and hope it would cool it down, but I knew its chances of survival […]

Ask a climate scientist: how does water vapor cause global warming?

Ask a climate scientist: how does water vapor cause global warming?

As we begin a new year — on a day that is hot and windy 40 degrees in Melbourne, I might add — these continuous questions about climate science and the issues surrounding climate change seem even more poignant.

We are fast approaching the final day of negotiations at the major UN Climate Summit for 2010. New meetings are being called around the clock as Heads of State and Environment Ministers attempt to secure a strong outcome from Cancun. In the past few hours a range of press conferences and non-government organisation briefings have […]

Ask a climate scientist: how is the global average temperature calculated?

A State of the Climate — Global Analysis report declared Jan-Oct 2010 as the hottest period on record just last month. The stats came from combining the global land and ocean surfaces temperatures and comparing them to past historical time periods. But how is a global average temperature calculated? How is an “average” created in a […]

He has landed himself in the middle of tense and fragile negotiations. There remains a mixed atmosphere of both optimism for success in Cancun and […]

It would be unrealistic to think that we could realistically do something useful

It would be unrealistic to think that we could realistically do something useful

“There was a realistic assessment . . . by the leaders that it was unrealistic to expect a full…. agreement.” That quote from U.S. deputy national security advisor for international economic affairs Michael Froman about his hopes for a final agreement in Copenhagen would be funny if wasn’t so, well… unfunny. The full quote: “I […]

The “Oh Shit” moment

The “Oh Shit” moment

Mark Hertsgaard in The Nation: They say that everyone who finally gets it about climate change has an “Oh, shit” moment–an instant when the full scientific implications become clear and they suddenly realize what a horrifically dangerous situation humanity has created for itself. It’s especially alarming when people who, ahem, know their shit, speak about […]
