Melting and Thawing
• Since 1900 the Northern Hemisphere has lost seven percent of the maximum area covered by seasonally frozen ground.
• Mountain glaciers and snow cover have declined worldwide.
• Satellite data since 1978 show that the extent of Arctic sea ice during the summer has shrunk by more than 20 percent.
3. The Third Assessment Report (TAR 2001) concluded that “most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentration.”

- The models used by the IPCC project that by the end of this century, the global average sea-level will rise between 7 and 23 inches (0.18 and 0.59 meters) above the 1980–1999 average.
- • “Increasing atmospheric carbon dioxide concentrations will lead to increasing acidification of the ocean,” with negative repercussions for all shell-forming species and their ecosystems.[5]
- The IPCC states that it is very likely that the Atlantic Ocean MOC will be 25 percent slower on average by 2100
- Melting Ice
  • Sea ice is projected to shrink in both the Arctic and Antarctic under all model simulations. Some projections show that by the latter part of the century, late-summer Arctic sea ice will disappear almost entirely.
- • Extreme heat, heat waves, and heavy precipitation are very likely to continue becoming more frequent.
- Increasingly Severe Weather
  (storms, precipitation, drought)
  • Tropical cyclones (hurricanes and typhoons) are likely to become more intense, with higher peak wind speeds and heavier precipitation associated with warmer tropical seas.
- Even if we act today to reduce our emissions from cars, power plants, land use, and other sources, we will see some degree of continued warming because past emissions will stay in the atmosphere for decades or more. If we take no action to reduce emissions, the IPCC concludes that there will be twice as much warming over the next two decades than if we had stabilized heat-trapping gases and other climate relevant pollutants in the atmosphere at their year 2000 levels.
- Rising Sea Levels
  • Since 1961, the world’s oceans have been absorbing more than 80 percent of the heat added to the climate, causing ocean water to expand and contributing to rising sea levels. Between 1993 and 2003 ocean expansion was the largest contributor to sealevel rise.
- • Droughts have become longer and more intense, and have affected larger areas since the 1970s, especially in the tropics and subtropics.
- Increasingly Severe Weather
  (storms, precipitation, drought)
  • The intensity of tropical cyclones (hurricanes) in the North Atlantic has increased over the past 30 years, which correlates with increases in tropical sea surface temperatures.
- Additional IPCC Findings on Recent Climate Change
  Rising Temperatures
  • Eleven of the last 12 years rank among the 12 hottest years on record (since 1850
- Warming Is Unequivocal
  The report concludes that it is “unequivocal” that Earth’s climate is warming, “as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level.”
- Human Responsibility for Climate Change
  The report finds that it is “very likely” that emissions of heat-trapping gases from human activities have caused “most of the observed increase in globally averaged temperatures since the mid-20th century.”
