A sweeping United Nations-sponsored review of climate science published Monday projected that the world will cross a crucial temperature threshold as early as 2030 — up to a decade sooner than previously thought.

Why it matters: Warming is affecting every area of the globe, the report notes, and extreme weather events are becoming more common and severe contributing to a more volatile world.
