Scientific consensus: Earth's climate is warming Temperature data showing rapid warming in the past few decades. According to NASA data, 2016 was the warmest year since 1880, continuing a long-term trend of rising global temperatures.

The 10 warmest years in the 138-year record all have occurred since 2000, with the four warmest years being the four most recent years. Multiple studies published in peer-reviewed scientific journals1 show that 97 percent or more of actively publishing climate scientists agree*: Climate-warming trends over the past century are extremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position.

The following is a partial list of these organizations, along with links to their published statements and a selection of related resources. AMERICAN SCIENTIFIC SOCIETIESStatement on climate change from 18 scientific associations"Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.

" (2009)2 American Association for the Advancement of Science "The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society.

" (2004)4 American Geophysical Union "Human‐induced climate change requires urgent action Climate change due to their proximity to the ocean and their reliance on it for resources and be found in the topic papers of the Science Review. 2018..

Humanity is the major influence on the global climate change observed over the past 50 years.

Rapid societal responses can significantly lessen negative outcomes. " (Adopted 2003, revised and reaffirmed 2007, 2012, 2013)5 American Medical Association "Our AMA .

supports the findings of the Intergovernmental Panel on Climate Change’s fourth assessment report and concurs with the scientific consensus that the Earth is undergoing adverse global climate change and that anthropogenic contributions are significant. " (2013)6 American Meteorological Society "It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide.

" (2012)7 American Physical Society "The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur.

We must reduce emissions of greenhouse gases beginning now.

" (2007)8 The Geological Society of America "The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the middle 1900s 5 hours ago - ExxonMobil agrees to join oil and gas climate change alliance Leaked document shows BusinessEurope group would oppose more .

" (2006; revised 2010)9International academies: Joint statement"Climate change is real. There will always be uncertainty in understanding a system as complex as the world’s climate.

However there is now strong evidence that significant global warming is occurring. The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and from phenomena such as increases in average global sea levels, retreating glaciers, and changes to many physical and biological systems.

It is likely that most of the warming in recent decades can be attributed to human activities (IPCC 2001). National Academy of Sciences "The scientific understanding of climate change is now sufficiently clear to justify taking steps to reduce the amount of greenhouse gases in the atmosphere.
