BP strongly reduced its fossil fuel production for many years. It is only now scaling up again after shareholder complaints about its underperformance. Therefore this ‘study’ linking heat to producers and a non-producer is bunk.
Not quite insane, but certainly deluded. Climate changes are cyclical. The evidence is in the geologic deposits. The reasons for climate change are primarily oscillations in the earth orbit and continental drift. The effects of dinosaur farts and cave man cooking fires are very minor.
