Every Scientific Society, every National Academy of Science, and every major University has statements that AGW is real, and a clear and present danger. That pretty well covers 97% of scientists.

He does...know better than gore's folly that is. He has way too much respect for his training and education than to join the algore boy's club and liar's society.

AGU Statement on Climate Change Climate Etc.
Human-induced climate change requires urgent action.
Humanity is the major influence on the global climate change observed over the past 50 years. Rapid societal responses can significantly lessen negative outcomes.
“Human activities are changing Earth’s climate. At the global level, atmospheric concentrations of carbon dioxide and other heat-trapping greenhouse gases have increased sharply since the Industrial Revolution. Fossil fuel burning dominates this increase. Human-caused increases in greenhouse gases are responsible for most of the observed global average surface warming of roughly 0.8°C (1.5°F) over the past 140 years. Because natural processes cannot quickly remove some of these gases (notably carbon dioxide) from the atmosphere, our past, present, and future emissions will influence the climate system for millennia.
Extensive, independent observations confirm the reality of global warming. These observations show large-scale increases in air and sea temperatures, sea level, and atmospheric water vapor; they document decreases in the extent of mountain glaciers, snow cover, permafrost, and Arctic sea ice. These changes are broadly consistent with long-understood physics and predictions of how the climate system is expected to respond to human-caused increases in greenhouse gases. The changes are inconsistent with explanations of climate change that rely on known natural influences.

The Geological Society of America - Position Statement on Climate Change
Given the knowledge gained from paleoclimatic studies, several long-term causes of the current warming trend can be eliminated. Changes in Earth’s tectonism and its orbit are far too slow to have played a significant role in a rapidly changing 150-year trend. At the other extreme, large volcanic eruptions have cooled global climate for a year or two, and El Niño episodes have warmed it for about a year, but neither factor dominates longer-term trends. Extensive efforts to find any other natural explanation of the recent trend have similarly failed.
As a result, greenhouse gas concentrations, which can be influenced by human activities, and solar fluctuations are the principal remaining factors that could have changed rapidly enough and lasted long enough to explain the observed changes in global temperature. Although the 3rd (2001) IPCC report allowed that solar fluctuations might have contributed as much as 30% of the warming since 1850, subsequent observations of Sun-like stars (Foukal et al., 2004) and new simulations of the evolution of solar sources of irradiance variations (Wang et al., 2005) have reduced these estimates. The 4th (2007) IPCC report concluded that changes in solar irradiance, continuously measured by satellites since 1979, account for less than 10% of the last 150 years of warming. Throughout the era of satellite observation, during periods of strong warming, the data show little evidence of increased solar influence (Foster and Rahmstorf, 2011; Lean and Rind, 2008).
Greenhouse gases remain as the major explanation for the warming. Observations and climate model assessments of the natural and anthropogenic factors responsible for this warming conclude that rising anthropogenic emissions of greenhouse gases have been an increasingly important contributor since the mid-1800s and the major factor since the mid-1900s (Meehl et al., 2004). The CO2 concentration in the atmosphere is now ~30% higher than peak levels that have been measured in ice cores spanning 800,000 years of age, and the methane concentration is 2.5 times higher. About half of Earth’s warming has occurred through the basic heat-trapping effect of the gases in the absence of any feedback processes. This “clear-sky” response to climate is known with high certainty. The other half of the estimated warming results from the net effect of feedbacks in the climate system: a large positive feedback from water vapor; a smaller positive feedback from snow and ice albedo; a negative feedback from aerosols, and still uncertain,feedbacks from clouds. The vertical structure of observed changes in temperature and water vapor in the troposphere is consistent with the anthropogenic greenhouse-gas “fingerprint” simulated by climate models (Santer et al., 2008). Considered in isolation, the greenhouse-gas increases during the last 150 years would have caused a warming larger than that actually measured, but negative feedback from aerosols and possibly clouds has offset part of the warming. In addition, because the oceans take decades to centuries to respond fully to climatic forcing, the climate system has yet to register the full effect of gas increases in recent decades.

2012 AMS Information Statement on Climate Change
Climate Change
An Information Statement of the American Meteorological Society
(Adopted by AMS Council 20 August 2012)
pdf version
The following is an AMS Information Statement intended to provide a trustworthy, objective, and scientifically up-to-date explanation of scientific issues of concern to the public at large.
Background
This statement provides a brief overview of how and why global climate has changed over the past century and will continue to change in the future. It is based on the peer-reviewed scientific literature and is consistent with the vast weight of current scientific understanding as expressed in assessments and reports from the Intergovernmental Panel on Climate Change, the U.S. National Academy of Sciences, and the U.S. Global Change Research Program. Although the statement has been drafted in the context of concerns in the United States, the underlying issues are inherently global in nature.
How is climate changing?
Warming of the climate system now is unequivocal, according to many different kinds of evidence. Observations show increases in globally averaged air and ocean temperatures, as well as widespread melting of snow and ice and rising globally averaged sea level. Surface temperature data for Earth as a whole, including readings over both land and ocean, show an increase of about 0.8°C (1.4°F) over the period 1901─2010 and about 0.5°C (0.9°F) over the period 1979–2010 (the era for which satellite-based temperature data are routinely available). Due to natural variability, not every year is warmer than the preceding year globally. Nevertheless, all of the 10 warmest years in the global temperature records up to 2011 have occurred since 1997, with 2005 and 2010 being the warmest two years in more than a century of global records. The warming trend is greatest in northern high latitudes and over land. In the U.S., most of the observed warming has occurred in the West and in Alaska; for the nation as a whole, there have been twice as many record daily high temperatures as record daily low temperatures in the first decade of the 21st century.
The effects of this warming are especially evident in the planet’s polar regions. Arctic sea ice extent and volume have been decreasing for the past several decades. Both the Greenland and Antarctic ice sheets have lost significant amounts of ice. Most of the world’s glaciers are in retreat.
Other changes, globally and in the U.S., are also occurring at the same time. The amount of rain falling in very heavy precipitation events (the heaviest 1% of all precipitation events) has increased over the last 50 years throughout the U.S. Freezing levels are rising in elevation, with rain occurring more frequently instead of snow at mid-elevations of western mountains. Spring maximum snowpack is decreasing, snowmelt occurs earlier, and the spring runoff that supplies over two-thirds of western U.S. streamflow is reduced. Evidence for warming is also observed in seasonal changes across many areas, including earlier springs, longer frost-free periods, longer growing seasons, and shifts in natural habitats and in migratory patterns of birds and insects.
Globally averaged sea level has risen by about 17 cm (7 inches) in the 20th century, with the rise accelerating since the early 1990s. Close to half of the sea level rise observed since the 1970s has been caused by water expansion due to increases in ocean temperatures. Sea level is also rising due to melting from continental glaciers and from ice sheets on both Greenland and Antarctica. Locally, sea level changes can depend also on other factors such as slowly rising or falling land, which results in some local sea level changes much larger or smaller than the global average. Even small rises in sea level in coastal zones are expected to lead to potentially severe impacts, especially in small island nations and in other regions that experience storm surges associated with vigorous weather systems.
There seems no doubt here.

Do scientists agree on climate change?
Yes, the vast majority of climate scientists – 97 percent – agree that humans are causing global warming and climate change. Most of the leading science organizations around the world have issued public statements expressing this, including international and U.S. science academies, the United Nations Intergovernmental Panel on Climate Change and a whole host of reputable scientific bodies around the world). The number of peer-reviewed scientific papers that reject the consensus on human-caused global warming is a vanishingly small proportion of the published research. The small amount of dissent tends to come from a few vocal scientists who are not experts in the climate field or do not understand the scientific basis of long-term climate processes.

Let's take a closer look at where this bullshit claim originated...
Global Warming Alarmists Caught Doctoring 97-Percent Consensus Claims - Forbes
Excerpt: the entire article is at the link above...
Global warming alarmist John Cook, founder of the misleadingly named blog site Skeptical Science, published a paper with several other global warming alarmists claiming they reviewed nearly 12,000 abstracts of studies published in the peer-reviewed climate literature. Cook reported that he and his colleagues found that 97 percent of the papers that expressed a position on human-caused global warming “endorsed the consensus position that humans are causing global warming.”
As is the case with other ‘surveys’ alleging an overwhelming scientific consensus on global warming, the question surveyed had absolutely nothing to do with the issues of contention between global warming alarmists and global warming skeptics. The question Cook and his alarmist colleagues surveyed was simply whether humans have caused someglobal warming. The question is meaningless regarding the global warming debate because most skeptics as well as most alarmists believe humans have caused some global warming. The issue of contention dividing alarmists and skeptics is whether humans are causing global warming of such negative severity as to constitute a crisis demanding concerted action.
Either through idiocy, ignorance, or both, global warming alarmists and the liberal media have been reporting that the Cook study shows a 97 percent consensus that humans are causing a global warming crisis. However, that was clearly not the question surveyed.
I'll throw another possibility (probability) out for the liberal media reporting this 97% mistake over and over and over. They were INTENTIONALLY LYING FOR ALGORE AND HIS GD CRONIES.

Global warming science is an odd phrase considering that theres not a shred of real science behind manmade global warming
Yes I know, and you are correct of course. Could you not just refer to them as "Beloved of Gaia" or some such euphemism. Yes: I have naughtily referred to them as "dogsh!t" in the past but that was in the badlands. Here mocking is not really "nice", even if based in fact.

Dear Frank,
I am quite prepared to say that there is a contribution to GW that is anthropogenic. The Heat Island effect is well established. But I cannot contribute ALL GW to humans. If it is as much as a third then I would be surprised. If nothing at all I would be less surprised.
