Less obviously, when you’re discussing future plans, and Climate Change might affect them, say so. Example: in seminars I ask about the effect of Climate Change during the Q&A. A few weeks ago, I went to a forum where my city’s water planners presented their plans. My city gets more than 90% of its water from snowpack, and snowpack has shrunk 15-30% in recent decades. The trend will accelerate with Climate Change but that wasn’t factored into the strategy, so I asked about it and it changed the discussion. I made it easier for everyone to discuss it and it was prominent in the rest of the Q&A. This tactic is especially nice because you can influence a lot of people with only a tiny effort.
