The importance of this principle is readily apparent: our world is changing, the degree of changes is projected to increase, and many of the consequences will create hardship for humans. Some key points are:
- The impacts of human-caused climate change are already being seen, from polar regions, to our backyards, to communities around the world.
- Consequences of climate change will affect the biosphere on many levels, from coral bleaching, to dying forests, to species extinction.
- Human infrastructure is threatened by a changing climate, such as encroachment of coastlines, stress to the energy grid, and shifting structures as a result of melting permafrost.
- A warming climate threatens mountain snowpacks, fresh water supplies and hydropower that serve millions of people.
- Changes in climate and precipitation patterns will impact agriculture and food security.
- Populations that are already vulnerable in terms of sea level rise and food security are poised for the greatest hardships. Political unrest, migration of refugees and global economic impacts are all possible outcomes.
