Guilty by emission

“MAN HAS A time window of five to ten years before the need for hard decisions regarding changes in energy strategies might become critical.” That is a summary of James Black’s research on climate change. He was a scientist at ExxonMobil and shared his findings with his bosses in 1978, while underscoring the scientific consensus on global warming. The warnings were ignored. Over the following three decades the oil firm’s bosses cast doubt on the consensus and lobbied vigorously against climate-friendly policies.
