Here's another climate feedback: More frequent and severe heat waves, such as the one breaking all kinds of records in the US at the moment, are one of the most likely effects of continued climate change. More severe/frequent heat waves mean higher peak electricity demand, which means more power stations being built, which means more capacity in the system, which means more impetus to use it, which means (barring widespread and rapid implementation of cleaner energy) more greenhouse gas emissions, which means - well, you get it by now.
