Global temperatures for February showed a disturbing and unprecedented upward spike, write Steve Sherwood and Stefan Rahmstorf.

Carbon dioxide concentrations in seawater could reach levels high enough to make fish “intoxicated” many decades earlier than previously thought, with serious implications for the world’s fisheries.

Rivers in many agriculturally significant areas of Australia could lose water as the landscape grows greener, write Anna Ukkola and Albert Van Dijk.

Global average temperatures will rise at least 4°C by 2100 if carbon dioxide emissions are not reduced, according to new UNSW research published in Nature.

Carbon dioxide levels have risen above 400 parts-per-million, but geoengineering is no alternative to reducing emissions, writes Professor Steve Sherwood.

A carbon price of between $50 and $100 per tonne would make coal-fired and gas-fired power less economical than renewable electricity, a UNSW study shows.

Corals

Shallow coral reefs may be even more susceptible to increasing acidity caused by heightened levels of carbon dioxide in the atmosphere and oceans than previously recognised.

The only sure way to stop the buildup of greenhouse gases in the atmosphere is to curb carbon dioxide emissions, write Steve Sherwood and Laurie Menviel.
