In other climate-related news, a new federal lawsuit takes aim at ExxonMobil in what advocates say is the first legal action targeting the oil giant for its decades-long cover-up of climate change. The suit, by the environmental group Conservation Law Foundation, charges ExxonMobil continues to pollute the Island End and Mystic rivers near Boston, in part by failing to fortify a storage facility to withstand rising seas and extreme weather caused by climate change. Last year, InsideClimate News and the Los Angeles Times revealed that for decades, beginning in 1977, Exxon concealed its own findings that fossil fuels cause global warming, alter the climate and melt Arctic ice.
