Shell plans its business on the assumption that global heating will not be curbed, and will proceed to global disaster.

Because these giant companies have so much influence, whatever they assume about the future is as much a decision as a forecast. If you suppose that global efforts to avert disaster will fail, that is pessimism; when Shell supposes this, that is sabotage.

This shows that the fossil fuel companies recognize what CO₂ will do to the Earth, even as their pet politicians deny it.
