Another good way that many people can become personally invested in efficiency/greenhouse gas emission reduction. It’s cheap, thus scalable. And the universe of older cars is at historic highs. Obviously, we’ll get greater impact by quickly increasing new vehicle efficiencies and moving to non-fossil-fuel vehicles ASAP, but this is a great interim step.

Still a lot unknown in this realm, e.g., what are the unknown impacts of relocation, what about changes in vegetation in relocation areas due to climate change, for what species would this work and which not, what prevents insect migration and what would be involved to successfully “transplant” these species. So, scalability and impact are [...]

Great concept.

Great idea where there is enough data (a real problem on many issues around the globe). Scalability is a challenge given the expense of the computing capability and the projection/visualization technology involved. But, there’s no better way I know of to help decision-makers understand the reams of data associated with complex issues, like climate change [...]

My evaluation is based on the limestone powder idea, since community-based engagement can work, change the game and is a sound idea IF the plan and participants are the right ones (i.e., outcome is highly dependent on a variety of variables). The outstanding question is whether the limestone powder treatment works in all salty soils [...]
