Founders Pledge has recently completed a large report on climate change, which recommends two new cost-effective climate change charities - the Clean Air Task Force and Coalition for Rainforest Nations. This is on our research page here (which also has a report on mental health and will be supplemented with a number of other in-house reports over the next few months). I know some EAs are interested in climate change and it is something we are often asked about. We have been relying on old GWWC research for a while so this should be a useful update.
It may also be of interest because both charities work on policy rather than doing direct work. Finally, there is some discussion of why we do not recommend Cool Earth.
Edit: there is also a discussion of the link between nuclear power and nuclear weapons that may be of interest to ex risk people
Borderline offtopic, but it would be great if you could provide a version of your research that is readable on a smartphone (aka no PDF).
I can second this. I prefer to download long pieces of text to my phone to read on Pocket/Instapaper. In addition, putting this report up as a web page will make it much more likely to be passed around on social media, Reddit, Hacker News, and so on.
