Earlier quoted context omitted.
It’s not that weird if you consider that despite the negative externalities all the CO2 producing processes delivered huge upsides to literally everybody. It’s not just Shell to blame, it’s all of us. We did this, we had good reasons to do so and now we should probably dial back.
The difference is that Shell, and other petroleum companies, knew the harm of CO2 for 50 years, consumers only half of that roughly. They could have start investing and do R&D on alternative and mitigation and help us move forward. But no, they just buried it under the rugs to get our money. That is deception, especially when they will not be the ones responsible for cleaning up the mess.
Had CO2 emissions been taken seriously — and given that successful predictions of the problem go back over a century we had plenty of time to plan — we could have bought additional decades to work on alternatives by continuing improvements in efficiency. Procrastinating means that we'll see more disruptive changes and worse climate impacts.
