Global warming

To me it's obvious that global warming is happening and that it is most likely caused by humans. I'm happy to put my trust in the thousands of extremely clever scientists who tell us that our planet is warming, they are the experts after all. But the twist is that I don't think it has to be all 'doom and gloom'. I put my faith in those same scientists to come up with a solution and in the meantime I'm doing everyinthg I can to help. Wherever possible I save energy and try to educate people about the problems we all face. This is a problem that could effect everyone on the planet, the problem is those people who are ignorant and selfish and for some strange reason dont think it is happening. Many thanks to stvasile for the link to the excellent WWF website!

There was a major debate 25 years ago about the impemding Ice Age. It gaint strength as we had a few winters in a row setting record low tempertures. It is interesting that they cite green house gases as the cause. As the earth is warming up so is the Moon and Mars. The sun is experiencing more solar activity and could be causing more energy to reach the earth. When someone pointed out that parts of the Artic region is experienceing thicker ice and incresing glaciers thickness, some of the Global Warming crowed uses that to prove that global warming can cause colder temptures. Global warming will cause increasinly stronger hurricanes and in the 2006-07 hurrican season the US will be hit with at lease 3 Catagory 5 hurricanes. Opps, we did not have a hurricane hit the US this pase season, maybe Golbal Warming will cause fewer hurricanes.

Global warming is the observed increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation. Global average air temperature near Earth's surface rose 0.74 ± 0.18 °C (1.3 ± 0.32 °F) during the last century. The Intergovernmental Panel on Climate Change (IPCC) concludes, "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. Other phenomena such as solar variation and volcanoes have probably had a warming effect from pre-industrial times to 1950, but a cooling effect since 1950.[1] These conclusions have been endorsed by at least 30 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. The American Association of Petroleum Geologists is the only scientific society doubting the predominant opinion,[2][3] but a few individual scientists also disagree with parts of it.[4] Models referenced by the 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 range of values reflects the use of differing scenarios of future greenhouse gas emissions as well as uncertainties regarding climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a millennium even if no further greenhouse gases are released after this date.[1] This reflects the long average atmospheric lifetime of carbon dioxide (CO2). An increase in global temperatures can in turn cause other changes, including sea level rise, and changes in the amount and pattern of precipitation. There may also be increases in the frequency and intensity of extreme weather events, though it is difficult to connect specific events to global warming. Other consequences may include changes in agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors. 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 political and public debate also 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 greenhouse gas emissions.

In February 2007 some of the world's leading scientists released a report showing the overwhelming scientific consensus that climate change is already upon us, and that human activities are the cause. But despite this and all the other evidence some people still aren't convinced. Perhaps you have a friend, a work colleague or even a family member who still thinks Global Warming is a myth? Well help is now at hand! http://www.panda.org/about_wwf/what_we_do/climate_change/problems/cause/climate_sceptics/index.cfm

well it is clear thanks to us we have caused global warming some more than some but what can I say our easy living comes at a cost to the atmosphere fridge stove factories ect are all contributions and we shall not mite but shall pay the price

Evidence for global warming can be found in every part of the Earth system. Besides well documented changes in air temperature, global warming is heating the world's oceans, reducing sea ice extent, especially in the Arctic, melting glaciers causing sea level to rise, altering habitats and affecting plant and animal distributions. There are many sceptics - many from the 'big business' community - the oil industry for example - who will continue to provide funding for a "disinformation" campaign that threatens to cloud serious scientific debate and stall the economic and political decisions that must be taken. Human activity is the major contributing factor to present day Global Warming. The effects are already present and they are going to get worse.

global warming is caused by the green house gases like carbon dioxide,methane,... some of the scientist say that it not by the emission of these gases because they would have been said to say for the industrialists whose whole family and their heridity depends on their business. but as a major issue the weaher changes is at its utmost. the climate tends to burn everyone everyday because of some people for their carelessness. to solve this industrialist must come forward to put equipments to reduce pollution caused by their factories into the atmosphere.
