Climate change and global warming - impacts and threats

Climate change is already beginning to transform life on Earth. Around the globe, seasons are shifting, temperatures are climbing and sea levels are rising. If we don’t act now, climate change will permanently alter the lands and waters we all depend upon for survival.

Some of the most dangerous consequences of climate change are listed here. Which one will have the most impact on your life, or on the places you care about?

Climate Change and Poverty

The 3 billion people who live in poverty around the world will be hardest hit by climate change. The poor are more dependent on natural resources and have less of an ability to adapt to a changing climate. Diseases, declining crop yields and natural disasters are just a few of the impacts of climate change that could devastate the world’s most vulnerable communities.

The world’s poorest are also the least responsible for climate change: The world’s least developed countries contribute only 10 percent of annual global carbon dioxide emissions.
