Newly available documents, both marked "SECRET," offer additional information on the previously undisclosed high-level Canadian government meeting on geoengineering held last summer (see Senior Canadian Government Meeting Looked at Geoengineering, 6/25). The first document, an internal Natural Resources Canada memo written in preparation for the July 5 meeting, indicates that geoengineering was the primary focus of the meeting, and that invitees consisted of officials at the deputy minister level. The memo is heavily redacted.
The second document is a slide deck that evidently served as Environment Canada's main presentation at the gathering. Titled "Geoengineering: Science and Governance," the deck provides a standard overview of geoengineering and its conventional breakdown into CDR and SRM methods. Interestingly, the concluding section, "Looking ahead," is completely redacted from the slide presentation.
