Reviewer 2 does geoengineering

By Andrew Lockley

Reviewer 2 quibbles with actual experts in Solar Radiation Modification and Carbon Dioxide Removal, before rejecting their work on spurious, spiteful and capricious grounds. You'd expect nothing less from R2.

HPAC takeover! Overshoot commission - Field

"Good afternoon, Reviewer 2 listeners. Some of us at the Healthy Planet Action Coalition (www.healthyplanetaction.org) have noticed that a few months ago Reviewer 2 experienced a security breach orchestrated by archrival Challenging Climate. Now normally we would refrain from taking advantage of poor Reviewer 2, but we sensed an opportunity that we couldn’t resist and decided to jump into the breach with this discussion about the recent report of the Climate Overshoot Commission (COC) between Chris Field, Stanford Professor and advisor to the COC, and Mike MacCracken, HPAC Steering Circle member and former Executive Director of the Office of the US Global Change Research Program.

The Climate Overshoot Commission report "Reducing the Risks of Climate Overshoot" was released on September 14: www.overshootcommission.org/_files/ugd/0c3b70_bab3b3c1cd394745b387a594c9a68e2b.pdf. While the COC did not solicit public input, it did hold a series of meetings to learn and discuss the full range of questions facing the international community in dealing with the risk of climate overshoot. Their 4-part high-level recommendations were summarized in the acronym CARE, for Cut (emissions), Adapt, Remove (CO2), and Explore (SRM). Specifically, its recommendation on climate intervention advocated expanding research while placing "a moratorium on the deployment of solar radiation modification and large-scale outdoor experiments that would carry risk of significant trans-boundary harm.
