Everything in nature—flowering, breeding, migration—lives and dies by a clock that is being recalibrated by climate change. We don’t yet know how severe the consequences may be.
Climate change has advanced the arrival of spring by as much as several weeks in some parts of the US. This can mean major crop losses and disconnects between species that need each other to thrive.
A recent study, one of the first of its kind, shows that migratory birds across all of North America are on the move sooner than than ever before as the result of climate change.
