This activity enabled those climate models, outside the major modeling centers to perform research of relevance to climate scientists preparing the IPCC Fourth Assessment Report (IPCC-AR4). For the CMIP3 a list of 20 different experiments were proposed, [3] and the PCMDI kept the documentation of all the global climate model involved. [4]
RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
CLIMAP map of ice sheets, sea temperature changes, and changes in the outline of coastal regions during the last glacial. Climate: Long range Investigation, Mapping, and Prediction, known as CLIMAP, was a major research project of the 1970s and 80s to produce a map of climate conditions during the Last Glacial Maximum.
Climate science was becoming more complicated and covering more disciplines. This small group of scientists lacked the resources to cover climate science. The United States Environmental Protection Agency sought an international convention to restrict greenhouse gas emissions.
The Climate Vulnerability Index (CVI), also referred to as Climate Change Vulnerability Index (CCVI), is a tool that identifies places that are susceptible to floods and heat-related effects of climate change by combining built, social, and ecological elements. [1] [2] It is also described as a systematic tool to rapidly assess climate change ...
Climate projections are based on emission scenarios. The emission scenarios used by the IPCC and by mainstream climate scientists are largely derived from the predicted demand for fossil fuels, and in our view take insufficient consideration of the constrained emissions that are likely due to the depletion of these fuels.

The Climate Change Science Program (CCSP) was the program responsible for coordinating and integrating research on global warming by U.S. government agencies from February 2002 to June 2009. [1] Toward the end of that period, CCSP issued 21 separate climate assessment reports that addressed climate observations , changes in the atmosphere ...
The World Climate Research Programme (WCRP) is an international programme that helps to coordinate global climate research. [1] The WCRP was established in 1980, under the joint sponsorship of the World Meteorological Organization (WMO) and the International Council for Science (ICSU), and has also been sponsored by the Intergovernmental Oceanographic Commission (IOC) of UNESCO since 1993.
