|Oil is not only a major contributor to global warming when it's burned, it's now the main source of revenue for the Islamic State (IS). The terrorist group which masquerades as a sovereign nation earns an estimated $1 million per day from selling oil it obtains in occupied regions of Iraq and Syria.
It's bad enough that the oil is mainly burned for transportation, upping the CO₂ load on the planet higher than anytime in the last 800,000 years. That's a load that we humans should have eliminated a long time ago by use of renewables. It's even worse that murderous IS is profiting from the crimes it commits—including selling oil which is mainly burned for energy.
There's no technological reason we can't eliminate fossil fuels we have today. It's a matter of paid-off politicians preventing the widespread adoption of renewables who are greedy and being bribed by Big Oil to stand in the way of progress. And, now those politicians are caught on the same side of the road as IS terrorists. They may not personally like or approve of IS, but they are definitely fellow travelers on the wrong side of the road.
As for the global warming denialists? Are they visibly-distinguishable from IS? They'd better wake up and smell the coffee!
