I moderated a panel at COP 29 that focused on how climate intervention may be beneficial for Ghana and Africa.

Ever wonder what the connection between inflation and climate change is? Now you can find out by watching this informative discussion on climate driven in inflation!

A study in Nature Communications examines Direct Air Capture’s role in climate-neutral aviation via synthetic fuels or carbon removal. It finds Direct Air Capture-based fuels can cost-effectively mitigate CO₂ and non-CO₂ effects if cheap renewable energy is used. https://go.nature.com/4ajmYuV 🧪

The Arctic–Boreal Zone is rapidly warming, impacting its large soil carbon stocks. Tundra regions may have already started to function on average as CO2 sources, demonstrating a shift in carbon dynamics. www.nature.com/articles/s41...

30% of the Arctic - 40% inc wildfires - is now a carbon source. Half of the Earth’s soil carbon pool is in the Arctic soil - more than there is in the atmosphere. The Arctic tipping point is at 1.5C - last year warming breached 1.6C The Arctic carbon sink is breaking down.
