Apologies for my silence recently – I just finished writing some final exams that I missed for the AGU conference, so I’ve been studying hard ever since Boxing Day.

I am working on a larger piece about climate models: an introduction to how they work and why they are useful. That will take about a week to finish, so in the mean time, here is an open thread to keep things moving.

Some possible discussion topics from posts I’ve enjoyed:

• Deep Climate’s analysis of Canada’s emissions, and why we probably won’t meet even the most meagre targets
• Bart Verheggen’s thoughts on climate scientists practicing what they preach
• David Archer on the methane situation

Enjoy!
