Incremental change is not enough if we want to limit temperature rises to 1.5°C, says the IPCC’s Working Group III, which includes UNSW sustainability expert Tommy Wiedmann.

A UNSW Sydney-led study shows at least two times more freshwater has shifted from warm to cold regions of the earth than our climate models predicted – signifying broader changes to the global water cycle.

Warming waters are leading to the ‘tropicalisation’ of temperate reefs: gone are the kelp forests, and local fish populations are responding unexpectedly.

Perhaps 2°C doesn't sound like much, but if you look through history, 2°C temperature changes have had huge effects on the planet and people.
