After the extreme weather patterns of this year can there be any doubt that something is going on? And even if climate change is only partially our fault (the other part being natural cycles in the Earth) then do we have the rights in the developed world to abuse our environment and resources at the expense of the Third world?
Global warming is definitely happening, and I think it is happening more rapidly than people expect. Every year we pump more CO2 into our atmosphere and it causes the earth to heat up exponentially. We need put in place energy alternatives. We already have solar and hydrogen technology.

Your so right this is a very terrible time we live in and it is happening.but we seem to survive somehow.I for one beleive in the great power of Mother Nature and evelution.so what will be will be and humans will always survive,They are just too beautiful,the good ones and I am sure the big guy loves them all.

Wow , This Topic is Getting posts , Ice bridge ruptures in Antarctic . An ice bridge linking a shelf of ice the size of Jamaica to two islands in Antarctica has snapped.
Scientists say the collapse could mean the Wilkins Ice Shelf is of the brink of breaking away, and provides further evidence or rapid change in the region.
Sited on the western side of the Antarctic Peninsula, the Wilkins shelf has been retreating since the 1990s.
Researchers regarded the ice bridge as an important barrier, holding the remnant shelf structure in place.
Its removal will allow ice to move more freely between Charcot and Latady islands, into the open ocean.
European Space Agency satellite pictures had indicated last week that cracks were starting to appear in the bridge. Newly created icebergs were seen to be floating in the sea on the western side of the peninsula, which juts up from the continent towards South America's southern tip.
Professor David Vaughan is a glaciologist with the British Antarctic Survey who planted a GPS tracker on the ice bridge in January to monitor its movement.
He said the breaking of the bridge had been expected for some weeks; and much of the ice shelf behind is likely to follow.
"We know that [the Wilkins Ice Shelf] has been completely or very stable since the 1930s and then it started to retreat in the late 1990s; but we suspect that it's been stable for a very much longer period than that," he told BBC News.
"The fact that it's retreating and now has lost connection with one of its islands is really a strong indication that the warming on the Antarctic is having an effect on yet another ice shelf . Over the past 50 years, the peninsula has been one of the fastest warming places on the planet.
Many of its ice shelves have retreated in that time and six of them have collapsed completely (Prince Gustav Channel, Larsen Inlet, Larsen A, Larsen B, Wordie, Muller and the Jones Ice Shelf).
Separate research shows that when ice shelves are removed, the glaciers and landed ice behind them start to move towards the ocean more rapidly. It is this ice which can raise sea levels, but by how much is a matter of ongoing scientific debate.
Such acceleration effects were not included by the UN's Intergovernmental Panel on Climate Change (IPCC) when it made its latest projections on likely future sea level rise. Its 2007 assessment said ice dynamics were poorly understood ,
i,m not Sure i think that yes Earth is warming in General , but i also think , The earth has been off kilter for a long time changing the Weather , some folks say we are going into an Ice Age - i,m Cold Here is all i know QC

Tiny Organisms Affected By Ocean Acidification, Global Warming
Posted on: Monday, 9 March 2009, 09:57 CDT
A new study found that ocean acidification caused by climate change is stripping away the protective shell of tiny yet vital organisms that absorb huge amounts of carbon pollution from the atmosphere, the American Free Press reported.
The study found that the calcium carapace of microscopic animals called foraminifera living in the Southern Ocean have fallen in weight by a third since the start of the Industrial Revolution.
The tiny organisms inhabit the surface waters of oceans around the world and are an important part of the ecological chain and also provide a bulwark against global warming.
The nearly microscopic creatures create calcium-based shells out of carbon dioxide (CO2) from the air. Their carbon-rich shells sink to the ocean floor when they die, effectively storing the atmospheric CO2 forever.
Studies in the past have suggested that other marine animals like corals are losing their ability to form exoskeletons from calcium. Potential causes range from rising temperatures and nutrient runoff from coastal agriculture to acidification.
The authors said it was the first study focus exclusively on acidification and tie it to greenhouse-gas pollution, which is driven especially by the invisible product of burning oil, gas and coal.
Co-author William Howard of the Antarctic Climate and Ecosystems Cooperative Research Center in Hobart, Tasmania, said it is the invasion of anthropogenic (man-made) CO2 that is causing this particular source of acidification.
As the shells drifted toward the sea floor, researchers collected shells of one foraminifera species, Globigerina bulloides, and compared them to older specimens that had sunk several hundred years earlier.
The authors wrote in the online edition of the journal Nature Geoscience that the newer shells had 30-to-35 percent less mass.
Howard said if forams and other shell makers are not making shells, it could change the transfer of carbon from the surface ocean into the deep ocean.
“That changes the efficiency of the biological pump, and would tend to lessen the degree to which the ocean takes up carbon,” he said in an interview with the American Free Press. “That's a feedback that we have to be concerned about.”
Scientists have only become aware of the extent of ocean acidification in the last five years and its potential to disrupt Earth's carbon cycle, which balances the absorption and release of CO2 into the atmosphere.
Howard said the problem with this impact is that it is so persistent and so long-lived, unlike other pollution carbons.
“We will have a harder time turning this impact around,” he said, adding that the geo-chemical mechanisms that buffer acidification work very slowly.
"It is like taking an antacid tablet for an upset stomach and then having to wait hundreds -- or thousands -- of years for it to work."
Experts fear that if the loss of shell mass threatens the survival of the amoeba-like creatures, it could also disrupt a food chain reaching from the plankton they eat, all the way up to large sea mammal such as whales.
"We don't know yet what those impacts might be," Howard said QC
Did not read everything here. Global warming is indeed real! How much of it is man-made or just the regular earth cycles will never really be know. Earth has gone through these same changes many times before. How can we conclude that man made this happened if these same changes had taken place without the benefit of modern society as we know it. Man always adapts to the changing world around us. There is no way we can stop it. We can watch it and do things to keep ourselves safe from these earth changes.
So it must have been cow and sheep breeders in the ancient days that are to be blamed for global warming then, huh? I say we are just in another earth changes and no matter how many pigs you put indoors for farming its still going to happen

Not what i said - we are over breading in an attempt to feed the mega populations of both free & incarcerated Humans - Global Warming is what is happening as the result of The Green House effect - cut back on the amount of heat getting yo the earth by adding reflective material getting into the atmospheres = problem solved ! QC
Overbreeding? Sorry but there are regulations that require pigs to be raised inside buildings with ventilations here in illinois. Not room to over breed. Believe me I eat my share of bacon to keep the popluation from bursting out the walls.
Global warming is another fluctuation the earth has alway gone through. No amount of anything will change that. Sure, maybe, humans have helped it along, but the earth was still going to go through this no matter what. All the plant life also require humans and animals to be around so they can live. They produce our oxygen we produce their carbon. No oxygen, no humans. No humans, no plant life. None of either no earth as we know it. This would me another Mars like planet.
Greenpeace occupies Parliament roofs to shoutâ€œClimate inaction costs livesâ€ 07 December 2009PrintSend to a friend On the opening day of pivotal climate change negotiations in Copenhagen, 19 Greenpeace activists have occupied roofs on the Parliament Buildings to highlight the failure of Prime Minister Harper and Opposition Leader Ignatieff to help end the growing loss of human lives from the ever-worsening climate crisis
Enlarge ImageOttawa, Canada â€” On the opening day of pivotal climate change negotiations in Copenhagen, 19 Greenpeace activists have occupied roofs on the Parliament Buildings to highlight the failure of Prime Minister Harper and Opposition Leader Ignatieff to help end the growing loss of human lives from the ever-worsening climate crisis.
The Greenpeace action targets Harper and Ignatieff for their failure to support legally binding, science-based targets that will lead to significant cuts in greenhouse gas emissions.
The activists have unfurled two 12 x 7 metre banners on the West Block of Parliament reading â€œHarper/Ignatieff: Climate Inaction Costs Livesâ€ and â€œHarper/Ignatieff: Lâ€™inaction climatique coÃ»te des vies.â€ Activists occupying roofs have also placed banners at the East Block and across entrances calling for an end to tar sands development. Harper and Ignatieff are failing to take seriously the staggering human tragedy of the climate crisis. Hundreds of thousands of people die every year and millions more are displaced because Canada and other developed counties donâ€™t take action on climate change. The Global Humanitarian Forum warns that this is just the beginning of the human tragedy of climate chaos.â€ â€” Mike Hudema, Greenpeace climate and energy campaigner, hanging from the roof of the West Block.
â€œHarper says he only supports modest reduction targets, Ignatieff has issued his climate thoughts without any reduction targets at all. Itâ€™s unacceptable for them to ignore the demand from Canadians for action. It is time Harper and Ignatieff stopped serving the interests of the dirty oil industry in the tar sands and helped lead the way to a just and ambitious climate agreement in Copenhagen. Millions of lives depend on climate action.â€ â€”Christy Ferguson, Greenpeace climate and energy campaign coordinator at the action.
This is the fifth action Greenpeace has undertaken since September to bring attention to climate inaction in Canada and the climate crimes of tar sands development.
Greenpeace and 120 partners have mobilized 150,000 Canadians through the KYOTOplus campaign to demand action from Ottawa to prevent climate chaos. Both Harper and Ignatieff have ignored requests to sign on to KYOTOplus and listen to Canadians who want action on climate change.
