56% – Do Americans Know Where Scientists Stand on Global Warming? – Yahoo! News

An overwhelming number of scientists (84%) say the earth is warming because of human activity, while just 4% of scientists say there is no solid evidence the earth is warming. Yet only 56% of Americans say that scientists agree that global warming is real and man-made. More than a third (35%) say scientists have not reached a consensus on climate change. The public’s perception of where the scientific community stands on climate change is tied to their own opinions on the issue. In a July Pew Research survey, about half the public (49%) said human activity is creating global warming. (It should be noted that an October Pew Research survey found far fewer Americans seeing solid evidence that humans are causing global warming.) Among this group, three-quarters (76%) said that scientists have reached a consensus on climate change and its cause. Among the 36% of Americans who said global warming is real but due to natural causes just 41% said there was a scientific consensus on the issue. And among those who said there is no evidence of climate change (11% of the public) a strong majority (68%) said there is no agreement among scientists on global warming. About one-in-five global warming skeptics (22%) say there is scientific agreement that human activity is causing climate change.

Man-made Causes of Global Warming
Man-made causes probably do the most damage to our planet. There are many man-made causes of global warming. Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also, mining coal and oil allows methane to escape. How does it escape? Methane is naturally in the ground. When coal or oil is mined you have to dig up the earth a little bit. When you dig up the fossil fuels you dig up the methane as well letting it escape into the atmosphere.

Another major man-made cause of Global Warming is population. More people means more food, and more methods of transportation. That means more methane because there will be more burning of fossil fuels (if you're into gas burning cars like our planet is), and more agriculture. If you've been in a barn filled with animals and you smelled something terrible, you were smelling methane. Another source of methane is manure. Because more food is needed to feed the population we have to raise food. Animals like cows are a source of food which means more manure and hence more methane. Another problem with the increasing population is transportation. More people means more cars, and more cars means more pollution. Also, many people have more than one car. There are definitely ways of raising animals and farming that use no manure and no methane. Once we realized the problem we should have stopped immediately using manure. Instead we choose to continue killing the planet. We are a very stubborn race.

Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2. Also, the trees that convert our CO2 to oxygen are being cut down because we're using the land that we cut the trees down from as property for our homes and buildings. We are not replacing the trees (trees are a very important part of our eco-system), so we are constantly taking advantage of our natural resources and giving nothing back in return.

Climate Change: Causes, Effects, and SolutionsHuman-induced climate change is a serious concern, drawing increasing attention from the media, policy makers and citizens around the world. This comprehensive and thought-provoking volume explains in easily understandable language the potential effects of climate change on our planet and our lives.

Climate Change: Causes, Effects and Solutions examines the latest scientific findings without any advanced technical knowledge. It goes beyond a description of changes in the physical environment to consider the broader issues of ecological, economic and human effects of climate change.

The book explains:

• the causes and effects of climate change from a natural and human environment perspective.
• mitigation options and policies that could reduce the impacts of climate change.
• global impacts -  with case studies are taken from North America, Europe, Australasia and elsewhere.

Essential reading for undergraduates and general readers who want to heighten their knowledge and understanding of this important problem.

Global Warming False Alarm: The Bad Science Behind the United Nations' Assertion that Man-made CO2 Causes Global Warming

Have you ever wondered why so many people believe recent climate change is almost entirely the result of human activity, even when there's plenty of evidence to the contrary? It's because the UN's Intergovernmental Panel on Climate Change (IPCC) says so.

This compact, readable book pulls apart the flawed science behind the IPCC's assertion that man-made CO2 is causing global warming. Author Ralph Alexander exposes the IPCC's deceptive manipulation of climate data, the roadblocks for the CO2 hypothesis favored by climate change alarmists, and the failed predictions of computer climate models.

Dr. Alexander goes on to examine the consequences of the erroneous, but widespread belief that CO2 emissions need to be drastically curbed for the health of the planet. His analysis shows the folly of carbon trading schemes for regulating CO2, together with common illusions about renewable energy sources. The enormous economic cost of cap-and-trade systems squanders our resources on a problem that doesn't even exist.

The book was awarded an eLit Gold Medal in March 2011, in the Environment/Ecology/Nature category, for books written in English and published electronically for the global marketplace.

What Causes Global Warming (Opposing Viewpoints)

Global Warming: Causes, Effects, and the Future

Planet Earth is warming faster now than at any other time in the past 1,000 years, and global warming may be the greatest threat to ever face humanity. Counteracting it is our greatest challenge.

 

Mark Maslin explains what global warming is and presents incontrovertible evidence that it is really happening. He examines the impact that climate change will have on health, agriculture, water resources, coastal regions, forests, and wildlife. He also looks at the efforts being made to counteract the effects of global warming and the ways in which we can adapt.
