Oceans and Cryosphere
A changing cryosphere affects us all
Changes to our oceans and cryosphere - the world's frozen places - have global climate impacts for nature and people. We're already seeing more extreme weather, extensive coral reef bleaching and sea level rise.
Ocean chemistry is changing
A warming ocean is more acidic and less oxygenated, affecting marine life and ultimately human communities.
It's already happening, and it's unstoppable
The polar regions will be profoundly different in the future. Some changes are irreversible for centuries - or more. Even if we stop greenhouse gas emissions tomorrow, the sea level will continue to rise - but taking action quickly can limit the worst impacts.
What can we do?
We need to urgently cut greenhouse gas emissions to limit the worst impacts to our oceans and cryosphere.
To become more resilient to the changes we cannot stop, we need to step up efforts to help people and nature adapt to a warmer world.

The IPCC report on Oceans and Cryosphere is a reminder that the systems we rely upon to sustain life on earth are losing their capacity to regulate the climate. We can't afford to let that happen. Dr. Stephen Cornelius, WWF’s IPCC lead and climate change chief adviser, explains. Read the blog post.
