Why did climate scientists emit 30,000 tonnes of C02 this weekend? | Peter Kalmus

Around 25,000 of my colleagues flew to a conference, leaving a colossal carbon footprint in their wake. This makes our warnings less credible to the public

This weekend, 25,000 Earth, Sun, and planetary scientists from across the US and abroad flew to New Orleans for the annual American Geophysical Union's Fall Meeting. These scientists study the impact global warming is having on Earth. Unfortunately, their air travel to and from the meeting will contribute to that warming by emitting around 30,000 tonnes of CO2.

As an Earth scientist and AGU member myself, I know the importance of their work. Still, there's something wrong with this picture. As scientists, our work informs us - with dreadful clarity and urgency - that burning fossil fuel is destroying the life support systems on our planet. There's already more than enough science to know we need to stop. Yet most scientists burn more than the average American, simply because they fly more.
