Verra recently announced that more than half of the credits from the Kariba REDD+ project don’t represent real climate benefits. Our new commentary explains why carbon market participants should treat Verra’s proposed solution to excess crediting with skepticism.
Verra doesn’t have a good solution for excess crediting – CarbonPlan
Verra recently acknowledged the existence of millions of excess credits issued to the Kariba REDD+ project. Rather than resolving the issue, Verra’s proposed solution exposes a fundamental structural ...

Last week I was playing around with a new "tree ring plot" to visualize daily global temperature anomalies from ERA5.
I thought it would be neat to make a version of the plot for daily global absolute temperatures (rather than anomalies):

To make all of this even worse: ethanol CCS is being falsely sold as a carbon removal offset. This @carbonplan.org post is a fantastic, readable breakdown of why ethanol CCS simply avoids extra carbon being released - rather than sucking carbon from the air.
