My complaint with Climate Change is the inability to hang a deer! 30 years ago, I could shoot a deer in gun season, and hang it in the barn to age the meat before butchering it. The temperature never got above 40F. Not any more. The temperatures in late Nov/early Dec these days routinely reach into the 50's. Now I pay the butcher and freezer do the same job. (not to mention, it's a LOT of work to butcher a deer, and I'm not so gung-ho at this age.)
As far as pond cooling goes, any little shade helps, so leave the boat in the water, float some logs, expand the dock, let the shoreline grow tall, ... If possible, bury the aerator supply hose or air-condition the supply air, so you're not bubbling 90F air through the water.
