Global warming and climate change effects
Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.
Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
Taken as a whole, the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time.
- Intergovernmental Panel on Climate ChangeScientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gasses produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1, 300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.
According to the IPCC, the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change.
The IPCC predicts that increases in global mean temperature of less than 1.8 to 5.4 degrees Fahrenheit (1 to 3 degrees Celsius) above 1990 levels will produce beneficial impacts in some regions and harmful ones in others. Net annual costs will increase over time as global temperatures increase.
"Taken as a whole, " the IPCC states, "the range of published evidence indicates that the net damage costs of climate change are likely to be significant and to increase over time."
Below are some of the impacts that are currently visible throughout the U.S. and will continue to affect these regions, according to the Third National Climate Assessment Report, released by the U.S. Global Change Research Program:
Northeast. Heat waves, heavy downpours, and sea level rise pose growing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries, and ecosystems will be increasingly compromised. Many states and cities are beginning to incorporate climate change into their planning.

How does global warming and climate change effect tornadoes? | Yahoo Answers
I would say that there's probably not much of an effect. Most tornadoes in the US (and the world for that matter) are cause when the cool air coming out of the Rocky Mountains collides with warm air coming up from the Gulf of Mexico, and this produces thunderstorms. It might be possible that with global warming, the air coming from the Gulf gets even warmer on average, and this could produce a few more tornadoes, but I've never seen any evidence to suggest that.
@CIA: There are ways to scientifically reverse the effects of global warming and climate change with lots of money right? I can save the world.
@Jaynie: You're not gonna convince me that global warming and the effects of climate change are a hoax. #sorrynotsorry
