hot spots

“Observational evidence from all continents and most oceans shows that many natural systems are being affected by regional climate changes, particularly temperature increases.” â€“Intergovernmental Panel on Climate Change (IPCC), 2007

Why You Need to Act Now
Substantial scientific evidence indicates that an increase in the global average temperature of more than 2°F above where we are today poses severe risks to natural systems and human health. To avoid this level of warming, the U.S. needs to reduce heat-trapping emissions by at least 80 percent below 2000 levels by 2050. Delay in taking such action today will mean facing the need for much steeper cuts later, which will likely be more difficult and costly.

Impacts of Global Warming

Global warming is already underway with consequences that must be faced today as well as tomorrow. Evidence of changes to the Earth’s physical, chemical and biological processes is now evident on every continent.

  • Sea levels are rising and glaciers are shrinking;
  • record high temperatures and severe rainstorms and droughts are becoming increasingly common.
  • Changes in temperatures and rainfall patterns alter plant and animal behavior and have significant implications for humans.

The Climate Hot Map arranges current and future climate impacts into five main groupings:

  • People
  • Freshwater
  • Oceans
  • Ecosystems
  • Temperature
