Climate: the changes & impacts of global warming

Impacts of climate change on nature.

Climate change is the biggest threat to nature and humanity in the 21st century.

Climate change news

The biggest threat

Climate change is everywhere

Today we are seeing the impacts of climate change around the globe - melting glaciers, rising sea levels, stronger storms, higher floods, less snow north and more drought south.

While individual events cannot be proof of serious climate change, multiple events, observations in nature, and observations by people living close to nature tell the full story.
 

Observations in nature

In almost 100 countries, WWF is working with people close to nature. By asking them about changes they see we are putting together a global map of Climate Witnesses which describe the creeping changes.
