What do experts think about global warming?
Climate Scientists all over the world are the experts on Global Warming. What they think about it is summarized below:
The InterGovernmental Panel on Climate Change (IPCC) was set up by the United Nations to examine and analyze all the peer-reviewed climate studies all over the world and assess them.
Their latest report: Fourth Assessment Report "Climate Change 2007" confirms what their earlier reports had found, that emissions of heat-trapping greenhouse gases like carbon dioxide from the burning of fossil fuels was 90 to 99% likely to be causing the global warming that has been observed over the past 50 years.
The US Global Change Research Program reported in June 2009:
Observations show that warming of the climate is unequivocal. The global warming observed over the past 50 years is due primarily to human-induced emissions of heat-trapping gases. These emissions come mainly from the burning of fossil fuels (coal, oil, and gas), with important contributions from the clearing of forests, agricultural practices, and other activities.
The Arctic Council and The International Arctic Science Committee reported in 2004 in their Arctic Climate Impact Assessment:
Climate conditions in the past provide evidence that rising atmospheric carbon dioxide levels are associated with rising global temperatures. Human activities, primarily the burning of fossil fuels (coal, oil, and natural gas), and secondarily the clearing of land, have increased the concentration of carbon dioxide, methane, and other heat-trapping ("greenhouse") gases in the atmosphere...There is international scientific consensus that most of the warming observed over the last 50 years is attributable to human activities.
- In 2001, 17 National Science Academies issued a joint statement regarding anthropogenic (man-made) global warming and urged people everywhere to reduce greenhouse gas emissions. This was signed by the National Science Academies of Australia, Belgium, Brazil, Canada, the Caribbean, China, France, Germany, India, Indonesia, Ireland, Italy, Malaysia, New Zealand, Sweden, Turkey, and the United Kingdom.
- In 2005, the Science Academies of Brazil, Canada, China, France, Germany, India, Italy, Japan, Russia, the United Kingdom, and the United States issued a similar joint statement.
- In 2007, following the 4th Report of the IPCC, a statement of support was signed by the National Science Academies of Brazil, Canada, China, France, Germany, Italy, India, Japan, Mexico, Russia, South Africa, the United Kingdom, and the United States.
- In 2008, in preparation for the G8+5 Meeting, the same thirteen countries issued a statement affirming "that climate change is happening and that anthropogenic warming is influencing many physical and biological systems."
- In 2009, the same thirteen countries affirmed that "climate change is happening even faster than previously estimated; global CO2 emissions since 2000 have been higher than even the highest predictions, Arctic sea ice has been melting at rates much faster than predicted, and the rise in the sea level has become more rapid."
I do not think that global warming is a myth. There are some who debate the reality of global warming, and others accept that it is happening but deny that humans are substantially responsible for global warming, but these debates simply prove there must be something to it. Global warming is no myth.
No. The risk is that by trying to hard too avoid criticism, scientific experts are failing in their duty to inform us fully of the facts and potential consequences of global warming. It is really because of the debate generated by non-experts who would deny some of the consequences of global warming, that some gain the impression that the 'middle ground' is in the middle - hence that the experts must be in some way…
it causes it because you have to think why do we have global warming if we didn't have global warming we might not be living right now and i know global warming is bad but if it wasn't for global warming we might not have snow, rain, cold and summer. that's what causes global warming. so I'm telling you this right now we better be thankful we have global warming if not one day we…
Al Gore is not a climate scientist, but a concerned citizen who has acquainted himself with the work of climate scientists. When he discusses facts about global warming, he will acknowledge that these are the facts according to the experts in the field. White ice reflects the suns rays much better than water. This means that as the polar sea ice melts due to global warming, there is less ice to reflect the heat, resulting…
What do you think is the biggest contributor to global warming What do you think can be done correct this?
Why we are using plastic bags in spite of global warming Earth-please do think about me! "Global warming, a Global warning" "Alone we can make a difference , but together we can change the world and protect our mother earth from global warming" "We're burning our children's inheritance" "Global Warming - A topic that's heating up" There are lots of possible slogans. Let's leave the world in usable condition for the next generation. Let's act…
The vast majority of climate scientists agree that global warming is happening and also that it is being caused by the actions of mankind. The reasons for it are the burning of fossil fuels and deforestation. There are some scientists who accept that global warming is real but they think there are other causes for it not caused by man. A tiny number don't think there is any warming at all.
Yes, Al Gore in convinced that global warming is real and a serious threat to the planet. He has spent time and energy educating people round the world about the causes and consequences of global warming. In 2006 he produced a movie "An Inconvenient Truth" which documents his campaign to bring global warming to the attention of the world.
True global warming does not decrease temperatures. So, either the model for global warming's effects is hokus-pokus, or global warming as presently claimed, does not exist. Some global warming followers will have you believe that global warming makes the weather "act crazy". If true, then it is not really global warming, is it.
