Increase in Global Temperature

Effects or consequences, the increase in temperature causes climate change, which can be physical, ecological, social and economic. Observed evidence of climate change includes the instrumental record of temperature, sea levels, and decreased snow cover in northern Hemisphere.Some the impact of rising temperatures are already underway.

The melting of ice in the world. This includes mountain glaciers, ice caps of Greenland and West Antarctica and covering the Arctic sea ice. Number of penguins in the Antarctic has dropped from 32,000 to 11,000 breeding pairs in 30 years.

sea level unexpectedly 7-23 inches (18 to 59 cm) at the end of the century. Between 1993 and 2003, the rate has increased over the previous period to 3.1 [2.4 to 3.8] mm per year. and more melt at the poles could add between 4 and 8 inches (10-20 cm).

What Hurricane Katrina and other storms can become stronger.Floods and droughts become more frequent. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.

Fresh water is less available. If the Quelccaya ice cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without any source either.Varieties diseases such as malaria carried by mosquitoes spread.Such.

Ecosystems are changing. According to scientists at the Wildlife Research Martyn Ob Bard, that since mid-1980, with less ice on which they live and fish for food, polar bears have got a lot thinner. Similarly, he found in the Hudson Bay polar bear biologist Ian Stirling. Fears that, if sea ice disappears, polar bears will be well.
