Climate change is already affecting every region on Earth. Changes in rainfall patterns, rising sea levels, melting glaciers, a warming ocean, and more frequent and intense extreme weather events are just some of the changes already impacting millions of people. (IPCC)

Climate change can affect our health, ability to grow food, housing, safety and work. Some of us are more vulnerable to climate impacts, such as people living in small island developing countries. Threats like sea-level rise and saltwater intrusion have advanced to the point where whole communities have had to relocate. In the future, the number of people displaced by climate change is expected to rise.
