Climate sensitivity, or how much the Earth's surface will warm if we double CO2, is one of the major questions in climate science. I take a look at 142 studies of sensitivity over last the two decades in the new @CarbonBrief explainer carbonbrief.org/explainer-ho…

What is climate sensitivity?

Are IAMs using too much BECCS? Many IAMs have land models, but independent studies generally have lower estimates. Crop yields & land availability key uncertainties. #negco2 @hausfath carbonbrief.org/analysis-how…

THREAD: What are SSPs, you ask? Well, they are about to shape climate policy discussions for the next 5-10+ years, so if you don't know about them, then you better read this @hausfath explainer... carbonbrief.org/explainer-ho…

MUST READ (if you are into climate change & carbon budgets) We may have blown the budget for 66% chance at 1.5°C 5 years ago, or we may have another 20 years at current emissions. @hausfath does a great job comparing recent estimates! carbonbrief.org/analysis-how…

Q&A: How do climate models work? | @rtmcswee @hausfath j.mp/2tWupHC

What are climate models?

Carbon Brief has taken an in-depth look at how and why scientists use climate models. Animation by Rosamund Pearce.

"I suspect in the next year or two ... we’ll start to see a lot more scenarios using lower levels of bioenergy with CCS" Here's hoping... The clock has started! scientificamerican.com/artic…

Tree Farms Will Not Save Us from Global Warming

Plantations would have to be massive in scale, and their value is still unproven
