Fossil fuels are the main driver of climate change and the terrifying effects of it that we see happening across the world. That makes this dataset a powerful tool for understanding how each of these entity’s heat-trapping emissions have contributed to climate change. The fossil fuel industry knew that too.

But what exactly would cause the AMOC to collapse?
