On Sunday, 11^th February 2018, I presented an Abstract of a 3 hour talk on the subject, “Carbon emissions and climate: Where do we stand, and what can be done if it all goes wrong?” at the Needham Lyceum, hosted at the Unitarian Universalist church, First Parish, Needham, Massachusetts, of which I am a proud member.

This talk, the slides, and a longer 3 hour exposition of the talk are now available at the First Parish site. To be clear, the links there are a recording of the talk at the Lyceum, which, because of time limits, was but 45 minutes. I visited a subset of the slides for that talk, also linked from that page. I also provided a longer talk which addressed each and every slide. That longer address is also available at that page.

The basic purpose of the talk was setting up a discussion of “climate hacking” or geoengineering which seems increasingly necessary, citing, for instance, the lectures and presentations of the great Wally Broecker at BU. I have linked presentations by Broecker and colleague, Klaus Lackner, here and here before.

I am happy to answer questions about the talk, either via the email address listed on the talk at the first slide, or at this blog, in its comments.
