Scientific positions on global warming
Decades of scientific research have shown that climate can change from both natural and anthropogenic causes. The report, which is about the effects that climate change is having in the United States, also said:. Stevens wrote: "The Intergovernmental Panel on Climate Change said the likelihood was 90 percent to 99 percent that emissions of heat-trapping greenhouse gases like carbon dioxide, spewed from tailpipes and smokestacks, were the dominant cause of the observed warming of the last 50 years. The five warmest were to The last century has seen a rapidly growing global population and much more intensive use of resources, leading to greatly increased emissions of gases, such as carbon dioxide and methane, from the burning of fossil fuels oil, gas and coaland from agriculture, cement production and deforestation. The Royal Society of New Zealand. With both rising seas and increasing drought, pressure for human migration could result on a large scale. Inthe geologist and historian of science Naomi Oreskes summarized a study of the scientific literature on climate change. The reality of global warming, its current serious and potentially disastrous impacts on Earth system properties, and the key role emissions from human activities play in driving these phenomena have been recognized by earlier versions of this ACS policy statement ACS,by other major scientific societies, including the American Geophysical Union AGU,the American Meteorological Society AMS, and the American Association for the Advancement of Science AAAS,and by the U.
Scientists worldwide agree that global warming is happening, and that human activity. Geological Society of America: Position Statement on Climate Change. Scientists have studied global warming for over years.
Global Warming is Happening and Humans are the Primary Cause Union of Concerned Scientists
Many thousands of experts have tested hypotheses, gathered evidence, constructed models, debated. That humans are causing global warming is the position of the Academies of Science from 19 countries plus many scientific organizations that study climate.
No paper on climate change consensus based on this survey has been published yet Februarybut one on another subject has been published based on the survey.
The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.

The globe is warming because of increasing greenhouse gas emissions. Holdrencited increased scientific confidence "that the kinds of harm already being experienced from climate change will continue to worsen unless and until comprehensive and vigorous action to reduce emissions is undertaken worldwide.
Current patterns of energy resources and energy usage are proving detrimental to the long-term welfare of humanity.
There is currently a strong scientific consensus that the Earth is warming and that this warming is mainly caused by human activities.
This consensus is supported by various studies of scientists' opinions and by position statements of scientific organizations. Scientific consensus is normally achieved through In the case of global warming, many governmental reports, the media in many of the abstracts expressed a position on anthropogenic global warming.
The EFG recognizes the work of the IPCC and other organizations, and subscribes to the major findings that climate change is happening, is predominantly caused by anthropogenic emissions of CO 2and poses a significant threat to human civilization.
AAPG respects these scientific opinions but wants to add that the current climate warming projections could fall within well-documented natural variations in past climate and observed temperature data.
