Pollution from fossil fuels causes one in five premature deaths globally, suggesting the health impacts of burning coal, oil and natural gas may be far higher than previously thought,  Parts of China, India, Europe and the northeastern United States are among the hardest-hit areas, suffering a disproportionately high share of 8.7 million annual deaths attributed to fossil fuels, the study published in the journal Environmental Research found.  The new research gives the most detailed assessment of premature deaths due to fossil-fuel air pollution to date. Another study in 2017 had put the annual number of deaths from all outdoor airborne particulate matter — including dust and smoke from agricultural burns and wildfires — at 4.2 million. - Reuters

Canada has underestimated its methane emissions from abandoned wells by 150 percent, and the USA by around 20%. While methane emissions from abandoned wells were reported to the United Nations as part of the U.S. and Canada’s greenhouse gas inventories, experts worry that there could be as many as 500,000 undocumented wells in the USA and 60,000 in Canada contributing to these emissions.  In 2018, in the USA alone, 3.2 million abandoned oil and gas wells emitted 281 kilotons of methane, equivalent in terms of climate change to consuming 16 million barrels of crude oil. - OilPrice.com
