How do you make a dinosaur burp in a bag? Measuring prehistoric methane

Last week my colleagues and I published a paper showing how methane emitted by dinosaurs could have affected the world’s climate. The media response was huge, with 100+ interviews by email and phone, and…

We need a more intelligent discussion about how to use our finite carbon, and it needs to be about metal. AAP

Treasure your metal: why we need to respect embedded energy

The recent furore about the carbon tax in this country has not been a celebration of enlightened debate. I think much of the debate misses a vital aspect of carbon use, namely, that using carbon to make…

There must be a better way. Wild Singapore

The end of field ecology?
