Welcome to nanfoster.com/global warming. I intend this site as a forum for people to share ideas about global warming/climate change, and steps we can take to ameliorate and cope with it. I welcome constructive, respectful discussions and will edit comments accordingly.
Here is what I wrote when I started this, but my viewpoints have changed: 
Two years ago: “I feel this issue is so urgent, and yet sometimes I feel doubtful that we can accomplish anything. Sometimes I feel unsure about what actions to support.”  
Now, I feel much more confident that we as a world can solve the problem. I know there is a lot of hope for a transition to a clean energy economy, and world leaders are making progress with the upcoming Paris talks. I think the changes will happen if we get large numbers of citizens to express that this is an urgent issue to them. Politicians will follow the people. 
I will link to articles and commentary about climate change, actions, and organizations working on these and related topics. I welcome your contributions, too.
