Fossil fuels produce an estimated > 4 million deaths per year [1]. This isn't even considering the hundreds of millions or more that are at risk of displacement due to climate change, and the conflict that will likely be associated with this displacement.

Also, can you substantiate your claim of several thousand extra deaths per year? I'm reading an estimated 5,000 additional cases of cancer (not all of them fatal) in all of Europe over the span of 20 years [2].
