Fossil fuel companies are funding a PR campaign that presents them as the saviours of humanity, to distract us from their plan to cause global disaster.

A study estimated that global heating would kill 100 million people by 2030. I expect the damage to accelerate as temperature rises ever faster; by 2050 it is likely to kill tens of millions per year.

Under these circumstances, even violent attacks on fossil fuel company installations could be justified on the grounds that they will prevent a bigger crime.
