![]() ![]() It is likely that most of the warming in recent decades can be attributed to human activities (IPCC 2001)." (2005, 11 international science academies) 10 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. ![]() However there is now strong evidence that significant global warming is occurring. There will always be uncertainty in understanding a system as complex as the world’s climate. Human activities (mainly greenhouse-gas emissions) are the dominant cause of the rapid warming since the middle 1900s (IPCC, 2013)." (2015) 9 Global Change Research Program (Melillo et al., 2014) that global climate has warmed in response to increasing concentrations of carbon dioxide (CO2) and other greenhouse gases. "The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2011), the Intergovernmental Panel on Climate Change (IPCC, 2013) and the U.S. "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 Statement on Climate Change from 18 Scientific Associations The following is a partial list of these organizations, along with links to their published statements and a selection of related resources. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. With that said, multiple studies published in peer-reviewed scientific journals 1 show that climate-warming trends over the past century are extremely likely due to human activities. This effort includes citing multiple peer-reviewed studies from research groups across the world, 1 illustrating the accuracy and consensus of research results (in this case, the scientific consensus on climate change) consistent with NASA’s scientific research portfolio. NASA Global Climate Change presents the state of scientific knowledge about climate change while highlighting the role NASA plays in better understanding our home planet. This is based on over a century of scientific evidence forming the structural backbone of today's civilization. Scientific evidence continues to show that human activities ( primarily the human burning of fossil fuels) have warmed Earth’s surface and its ocean basins, which in turn have continued to impact Earth’s climate. You can find the unclassified version of the ODNI UAP report on ’s important to remember that scientists always focus on the evidence, not on opinions. ![]() The All-Domain Anomaly Resolution Office (AARO) is leading DOD's efforts, in coordination with ODNI and other government agencies, to document, analyze, and when possible resolve UAP reports using a rigorous scientific framework and a data-driven approach. We take reports of incursions into our designated space, land, sea, or airspaces seriously and examine each one. operations security on land, in the skies, seas, and space are paramount. The safety of our service personnel, our bases and installations, and the protection of U.S. Yesterday the Director of National Intelligence delivered to Congress the Annual Report on Unidentified Aerial Phenomena (now Unidentified Anomalous Phenomena (UAP)) as required by the National Defense Authorization Act for Fiscal Year 2022.Īnalyzing and understanding the potential threats posed by UAP is an ongoing collaborative effort involving many departments and agencies, and the Department thanks the Office of the Director of National Intelligence (ODNI) for leading a collaborative effort to produce this report, as well as the other contributing departments and agencies.
