Since the Global Warming: Early Warning Signs map was originally released in November 1999, the picture of how global warming can affect us has become increasingly clear. By now it is very apparent that a warming climate could have substantial and direct impacts on the health of our ecosystems, food and water sources, and on humans, especially children and the elderly. It is well understood that these impacts will occur around the globe and will disproportionately affect the poorest members of our global community.
