can i get information about global warming?

Question

detail about it

Answer 1

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades and its projected continuation. Models referenced by the Intergovernmental Panel on Climate Change (IPCC) predict that global temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100.[1] The uncertainty in this range results from both the difficulty of predicting the amount of future greenhouse gas emissions and uncertainties regarding climate sensitivity.

Global average near-surface atmospheric temperature rose 0.6 ± 0.2 °Celsius (1.1 ± 0.4 °Fahrenheit) in the 20th century. The prevailing scientific opinion on climate change is that "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations,"[1] which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Greenhouse gases are released by activities such as the burning of fossil fuels, land clearing, and agriculture. Other phenomena such as solar variation have had smaller but non-negligible effects on global temperature trends since 1950.[2]

An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors. Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global warming. Although most studies focus on the period up to 2100, even if no further greenhouse gases were released after this date, warming (and sea level) would be expected to continue to rise for more than a millennium, since CO2 has a long average atmospheric lifetime.

Remaining scientific uncertainties include the exact degree of climate change expected in the future, and especially how changes will vary from region to region across the globe. A hotly contested political and public debate has yet to be resolved, regarding whether anything should be done, and what could be cost-effectively done to reduce or reverse future warming, or to deal with the expected consequences. Most national governments have signed and ratified the Kyoto Protocol aimed at combating global warming. (See: List of Kyoto Protocol signatories.)

Answer 2

there's tons of information out there....just do a google search. Here's the latest IPCC report if you really want the details. It was compiled by many of the world's leading scientists and includes the skeptics as well as those who are 'believers'. The time to deny global warming is LONG past and, besides, who out there thinks continuing to put filth into our air and water is a GOOD thing? The stakes are way too high to take a chance that there are 'natural cycles'. That debate is long over. Here's a link to the actual report.

Also, we don't have to learn to do with less...we only have to do it smarter through CLEAN and RENEWABLE energy. Many Americans are dying in Iraq right now largely, if not entirely, because of our dependence/addiction to foreign oil.

Answer 3

Wikipedia has a comprehensive page, other than that id just search engine it.
If your interested in global warming, research 'Global Dimming' thats also a by product of the way we live, its seriously interesting and quite frightening.

Answer 4

GLOBAL WARMING IS THE HEATING OF THE EARTH DUE TO AN INCREASED LEVEL OF CARBON DIOXIDE AND OTHER CARBON EMISSIONS.

HOWEVER SOME ARGUE THAT GLOBAL WARMING ISNT ACTUALLY HAPPENING ITS JUST PART OF THE EARTHS NATURAL CYCLE...I.E. CHANGING FROM COLD TO HOT ETC

Answer 5

Yes just go onto a search engine and you'll find loads of detail.

Answer 6

if you wanna be a victim to the porpagana machine go to town, evnviormentalists are just another word for people with too much time on their hands.

Answer 7

Ask Al Gore.
