The United States Global Change Research Program releases the findings of the National Assessment of the Potential Consequences of Climate Variability and Change. The assessment finds that temperatures in the United States will rise by 5 to 9°F (3–5°C) over the next century and predicts increases in both very wet (flooding) and very dry (drought) conditions.
|2002 Second hottest year on record. Heavy rains cause disastrous flooding in Central Europe leading to more than 100 deaths and more than $30 billion in damage. |
Extreme drought in many parts of the world (Africa, India, Australia, and the United States) results in thousands of deaths and significant crop damage.

|2007 IPCC’s fourth assessment report says glacial shrinkage, ice loss, and permafrost retreat are all signs that climate change is underway now. They predict a higher risk of drought, floods, and more powerful storms during the next 100 years. As a result, hunger, homelessness, and disease will increase. The atmosphere may warm 1.8 to 4.0˚C and sea levels may rise 7 to 23 inches (18 to 59 cm) by the year 2100.|
