Oil companies knew about climate change decades ago.
Instead of facing the reality of decarbonization, they chose to muddy the data via lobbying, spin and their own bunk science. Why? Because money! They sold out the planet for the almighty dollar.
But let's not only blame oil companies. For they operate within the framework provided to them. If politicians weren't compromised, a series of regulations, incentives and disincentives could have been implemented to shift society away from carbon-producing activities.
But alas, politicians have been bought and paid for by the energy industry. And for their sins, we all must suffer.
