An article in Nature* profiles a meticulous researcher who has shown that a small handful of companies were responsible for the vast majority of all carbon emissions, and that well over half of those emissions happened since my own children were in elementary school. Scary.
“The result, peer reviewed and published in Climatic Change, showed that just 90 companies contributed 63% of the greenhouse gases emitted globally between 1751 and 2010. Half of those emissions took place after 1988—the year James Hansen of NASA testified to Congress that there was no longer any doubt that global warming had begun.”
(* Nature is the magazine of the AAAS (formerly known as the American Association for the Advancement of Science). Most of its articles are quite dry and technical descriptions of rigorous scientific experiments in every field that currently exists. It is not a propaganda sheet!)
