Pacific island nations have shaped the international response to climate change. At the United Nations summit in Glasgow, they’ll draw a line in the sand.
Solar geoengineering could theoretically cool the Earth to slow global warming, and it has been controversial. Still, countries should research its risks and benefits.

Sharks grow slowly and produce few young compared to bony fishes. In many cases, this means that their populations are fished out faster than can be replenished if not well managed.
A study of 183 coral reefs worldwide quantified the impacts of ocean warming and acidification on reef growth rates. Even under the lowest emissions scenarios, the future of reefs is not bright.

The Mediterranean region, with its biodiversity, climate, demographics, and economic activities such as tourism, agriculture and fisheries, is particularly vulnerable to environmental risks.

In the ocean, phytoplankton helped by diazotrophs play an outstanding role in withdrawing CO₂ from the atmosphere. But climate change is disturbing this delicate balance.
The Pacific Ocean produces oxygen, helps regulates the weather, provides food and livelihoods. It’s a place of fun, solace and spiritual connection. But its delicate ecology is under threat.
What if the nightly news had regular updates on forest clearing, ocean temperatures and fossil fuel consumption? These indicators sit alongside temperatures as signs of climate change.
A new Intergovernmental Panel on Climate Change report makes clear human-induced climate change threatens the health and function of the ocean and cryosphere - the frozen regions of the Earth.
Acidic oceans are disrupting a major part of the carbon cycle, slowing how seas absorb carbon from the atmosphere. This could massively speed up the effects of climate change.v
In a study that cultivated coral ‘gardens’ with varying numbers of species, plots with more species were healthier. This finding could inform strategies to help coral reefs survive climate change.
Australia is facing an increase in extreme heat, fire danger weather, floods and marine heatwaves, according to the latest biennial snapshot from the Bureau of Meteorology and CSIRO.
