More time …. really?

A recent paper about [e]mission budgets and pathways consistent with limiting warming to 1.5 °C essentially argues that it is still possible to follow an emission pathway that will give us a good chance of keeping warming below 1.5oC. More specifically, … Continue reading

Manichean paranoia

Some have encouraged me to watch Roger Pielke Jr’s presentation on Climate politics as a manichean paranoia, and I have now done so (slides here, and I’ll post the video at the end of the post.). Manichean paranoia refers to … Continue reading

I thought I would post this video of Glen Peters discussing the three years we’ve just had in which there has been near-zero growth in emissions. You can use a Kaya-like identity to try and understand what might be causing … Continue reading

Oh no, not again
