Washington — Approximately 18,000 miles of decommissioned oil and gas pipelines in the Gulf of Mexico pose safety and environmental risks, according to a new report from the Government Accountability Office.

Researchers have modelled the exposure to multiple hazards across different regions of Europe in relation to heat, cold, drought, wildfire, flooding and wind. The study indicated that, over the next century, environmental hazards are likely to increase, particularly along coastlines and on floodplains, and that south-western Europe is likely to be the worst-hit region.
