The Environmental Protection Agency (EPA) on Tuesday issued a final decision to block a large proposed gold and copper mining project in Alaska's Bristol Bay watershed, which is home to dozens of Alaska Native villages and communities and is the site of one of the most valuable wild salmon fisheries in the world.

A new study relying on machine learning methods finds the climate thresholds enshrined in the Paris Agreement may be coming up faster than previously anticipated.
Why it matters: The world is already suffering the impacts of 1.1°C (1.98°F) to 1.2°C (2.16°F) of warming to date, and passing 1.5°C or 2°C above preindustrial levels could dramatically increase the risks to society and ecosystems.
