Landmark Document from Feds on Climate Change

Our friend Bill Brown in Taos at NMGlobalWarming.org reports on the U.S. federal government's Climate Change Science Program Report.
______________
Greetings, All -- The USA federal government's Climate Change Science Program (CCSP) released a new report yesterday on the impacts of climate change on the United States. While providing information on trends and projections for the future, the report also states how climate has already changed throughout the USA because of the impacts of human activity on our planet.

The CCSP reiterates what has long been known to science: The primary reason for climate change is human-generated increases in greenhouse gas concentrations.

The CCSP was authorized by federal legislation known as the Global Change Research Act of 1990. This Act spawned collaborative federal research and later the U.S. Global Change Research Program (USGCRP), through which the USA has made a total investment of almost $20 billion during the past thirteen years -- the world's largest investment in scientific research in the areas of climate change and global change. "The USGCRP, in collaboration with several other national and international science programs, has documented and characterized several important aspects of the sources, abundances and lifetimes of greenhouse gases; has mounted extensive space-based monitoring systems for global-wide monitoring of climate and ecosystem parameters; has begun to address the complex issues of various aerosol species that may significantly influence climate parameters; has advanced our understanding of the global water and carbon cycles (but with major remaining uncertainties); and has developed several approaches to computer modeling of the global climate."


The Summary of the 271-page document begins:

"Over the past several years, our understanding of global environmental change and our ability to estimate its future effects has improved significantly. In order to summarize the key conclusions of this research, the U.S. Climate Change Science Program (CCSP) has undertaken a national scale “Scientific Assessment of the Effects of Global Change on the United States.” The conclusions in this assessment build on the vast body of observations, modeling, decision-support, and other types of activities conducted under the auspices of CCSP. It draws on findings from previous assessments of the science, including reports and products by the Intergovernmental Panel on Climate Change (IPCC), CCSP, and others. Together with CCSP’s 21 Synthesis and Assessment Products, this is arguably the most comprehensive assessment to date of the effects of global change, and especially climate, on the United States. This fact sheet summarizes the key findings of the Assessment."



To download the Summary and/or the Full Report, or simply to learn about the history, quality and scope of the USA's Climate Change Research Program, see: http://www.climatescience.gov/



The CCSP considers this a landmark document, representing summary work of its almost two decades of research. Please take the time to read the Summary even if you do not wade through the full report.
