Paleoclimate Modelling Intercomparison Project
The Paleoclimate Modelling Intercomparison Project is a project, somewhat along the lines of AMIP or CMIP, to coordinate and encourage the systematic study of atmospheric general circulation models (AGCMs) and to assess their ability to simulate large climate changes such as those that occurred in the distant past. Project goals include identifying common responses of AGCMs to imposed paleoclimate "boundary conditions," understanding the differences in model responses, comparing model results with paleoclimate data, and providing AGCM results for use in helping in the analysis and interpretation of paleoclimate data. PMIP is initially focussing on the mid-Holocene (6,000 years before present) and the Last Glacial Maximum The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent. Ice sheets covered much of Northern North America, Northern Eur ... (21,000 yr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bethesda, Maryland
Bethesda () is an unincorporated, census-designated place in southern Montgomery County, Maryland. It is located just northwest of Washington, D.C. It takes its name from a local church, the Bethesda Meeting House (1820, rebuilt 1849), which in turn took its name from Jerusalem's Pool of Bethesda. The National Institutes of Health's main campus and the Walter Reed National Military Medical Center are in Bethesda, in addition to a number of corporate and government headquarters. As an unincorporated community, Bethesda has no official boundaries. According to the 2020 U.S. census, the community had a total population of 68,056. History Bethesda is located in a region that was populated by the Piscataway and Nacotchtank tribes at the time of European colonization. Fur trader Henry Fleet became the first European to visit the area, reaching it by sailing up the Potomac River. He stayed with the Piscataway tribe from 1623 to 1627, either as a guest or prisoner (historical accounts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intergovernmental Panel On Climate Change
The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations. Its job is to advance scientific knowledge about climate change caused by human activities. The World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) established the IPCC in 1988. The United Nations endorsed the creation of the IPCC later that year. It has a secretariat in Geneva, Switzerland, hosted by the WMO. It has 195 member states who govern the IPCC. The member states elect a bureau of scientists to serve through an assessment cycle. A cycle is usually six to seven years. The bureau selects experts to prepare IPCC reports. It draws the experts from nominations by governments and observer organisations. The IPCC has three working groups and a task force, which carry out its scientific work. The IPCC informs governments about the state of knowledge of climate change. It does this by examining all the relevant scientific literature ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livermore, California
Livermore (formerly Livermorès, Livermore Ranch, and Nottingham) is a city in Alameda County, California. With a 2020 population of 87,955, Livermore is the most populous city in the Tri-Valley. It is located on the eastern edge of California's San Francisco Bay Area. The current mayor is Bob Woerner. Livermore was platted and registered on November 4, 1869, as a railroad town by and named for Robert Livermore, his friend and a local rancher who settled in the area in the 1840s. It is the home of the Lawrence Livermore National Laboratory, for which the chemical element livermorium is named (and thus, placing the city's name in the periodic table). It is also the California site of Sandia National Laboratories, which is headquartered in Albuquerque, New Mexico. Its south side is home to local vineyards.

Seasonal Prediction Model Intercomparison Project
A season is a division of the year based on changes in weather, ecology, and the number of daylight hours in a given region. On Earth, seasons are the result of the axial parallelism of Earth's tilted orbit around the Sun. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant. Various cultures define the number and nature of seasons based on regional variations, and as such there are a number of both modern and historical cultures whose number of seasons varies. The Northern Hemisphere experiences most direct sunlight during May, June, and July, as the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to season ...

Coupled Model Intercomparison Project
In climatology, the Coupled Model Intercomparison Project (CMIP) is a collaborative framework designed to improve knowledge of climate change. It was organized in 1995 by the Working Group on Coupled Modelling (WGCM) of the World Climate Research Programme (WCRP). It is developed in phases to foster the climate model improvements but also to support national and international assessments of climate change. A related project is the Atmospheric Model Intercomparison Project (AMIP) for global coupled ocean-atmosphere general circulation models (GCMs). Coupled models are computer-based models of the earth's climate, in which different parts (such as atmosphere, oceans, land, ice) are "coupled" together, and interact in simulations. CMIP phases The Program for Climate Model Diagnosis and Intercomparison (PCMDI) at Lawrence Livermore National Laboratory has been supporting the several CMIP phases by helping WGCM to determine the scope of the project, by maintaining the project's ...
