Misusing Carbon Removal as a Climate Response

Carbon removal is an alluring idea. That also makes it a tempting façade for bad policies.

It seems clear that in some form, carbon removal is going to be an important component of climate policy, especially later in the century to deal with carbon levels that overshoot the targets in the Paris Climate Agreement. The problem is not with the concept but with its misuse.    One of the risks that …


Is “carbon management” just another COP-out?

Fudging the differences between carbon capture and carbon removal risks weakening climate action

Emissions cuts alone will (almost certainly) not keep the global average temperature rise below 1.5°C. But some optimism remains. Alongside a rapid phase-out of fossil fuels, substantial deployment of carbon dioxide removal (CDR) techniques might avert – or at least limit – overshoot of 1.5°C. At COP 28 this week the US and several partners …


Don’t hamstring carbon removal

California needs to lead in developing critical carbon removal technologies

Assessments by the IPCC have made clear that the most feasible way for the world to meet its target of restricting climate change to below two degrees Celsius of warming includes rapid and massive expansion of carbon removal technology – technology that would extract carbon dioxide and permanently sequester that carbon dioxide underground.  California has …


Time to Get Serious about Climate Change and Oceans

Science can unlock powerful tools to fight climate change and ocean acidification, but only if we fund research and govern it well.

  In the Before Time, I spoke with a few ocean scientists on climate issues, and I heard a common refrain. Climate change receives little attention or funding, considering the magnitude of the problem; climate impacts on oceans get even less; and marine carbon removal gets almost none at all. Humans are short-lived terrestrial creatures. …
