1/ What can you, a software engineer, do to fight #ClimateChange? My initial answer continues to be politics (https://codewithoutrules.com/2019/09/10/software-developers-climage-change/) but I now have a secondary answer.

There's a lot of software out there and it's ludicrously inefficient. Not because people don't care, but because no one bothered to look, or the cost is spread across millions of people, or because no one has time (open source! it's fun.)

Let me give you some examples—

What can a software developer do about climate change?

Pines and firs are dying across the Pacific Northwest, fires rage across the Amazon, it’s the hottest it’s ever been in Paris—climate change is impacting the whole planet, and things are not getting any better.
