The 2010s may go down in environmental history as the decade when the fingerprints of climate change became evident in extreme weather events, from heat waves to destructive storms, and climate tipping points once thought to be far off were found to be much closer.

And when climate scientists, seeing the evidence before them, cast away their reluctance to publicly advocate for action.
