Abrupt climate change refers to an event where large and widespread climate change occurs within about five years. A regional drought such as the Dust Bowl of 1932-1938 is the most familiar climate change on this time scale, but the phrase was coined because of worldwide, centuries-long events seen in ice cores of past climate. At least two modes of climate are now recognized: a warm-and-wet climate like today's and a climate that is cooler, drier, windy and dusty. An ice age is often in the latter mode but climate may chatter between the two modes with only minor changes in glaciers, dropping into the dry mode for centuries, popping up into warm-and-wet with only a five year transition, and then crashing back down again after a few more centuries. About 25 such Dansgaard-Oeschger cycles have been identified in the past 100,000 years. The last one was the Younger Dryas which began 12,900 years ago and popped back up into warm-and-wet about 11,600 years ago. There are also abrupt climate changes with sudden onset and gradual recovery, such as the half-sized event 8,200 years ago associated with a meltwater surge into the Labrador Sea. The human population has grown a thousand times since the last major flip; were the transitions spread out over 500 years, civilizations would likely adapt. A five-year transition into worldwide drought would likely produce major wars over remaining resources. ...more on Wikipedia about "Abrupt climate change"
The Asia-Pacific Partnership for Clean Development and Climate, also known as AP6, is an international non- treaty agreement between Australia, India, Japan, the People's Republic of China, South Korea, and the United States announced July 28 2005 at an Association of South East Asian Nations (ASEAN) Regional Forum meeting and launched on January 12 2006 at the Partnership's inaugural Ministerial meeting in Sydney. Foreign, Environment and Energy Ministers from partner countries agreed to co-operate on development and transfer of technology which enables reduction of greenhouse gas emissions. Ministers agreed a Charter, Communique and Work Plan that outline a ground-breaking new model of private-public taskforcess to address climate change, energy security and air pollution. ...more on Wikipedia about "Asia-Pacific Partnership for Clean Development and Climate"
Atmospheric Model Intercomparison Project (AMIP) is a standard experimental protocol for global atmospheric general circulation models (AGCMs). It provides a community-based infrastructure in support of climate model diagnosis, validation, intercomparison, documentation and data access. Virtually the entire international climate modeling community has participated in this project since its inception in 1990. ...more on Wikipedia about "Atmospheric Model Intercomparison Project"
The atmospheric window refers to those parts of the electromagnetic spectrum that are, with the earth's atmosphere in its natural state, not absorbed at all. The atmospheric window lies approximately at wavelengths of infrared radiation between 8 and 15 micrometres. ...more on Wikipedia about "Atmospheric window"
Attribution of recent climate change attempts to discover what mechanisms are responsible for the observed changes in climate. The endeavour centers on the observed changes over the last century and in particular over the last 50 years, when observations are best and human influence greatest. ...more on Wikipedia about "Attribution of recent climate change"
The Blytt-Sernander classification, or sequence, is a series of north European climatic periods or phases based on the study of Danish peat bogs by Axel Blytt (1876) and Rutger Sernander (1908). The classification was incorporated into a sequence of pollen zones later defined by Lennart von Post. ...more on Wikipedia about "Blytt-Sernander"
The phrase broad spectrum revolution refers to the way people adapted to the end of an ice age in the post- glacial environment following the around 15,000 BP in the Middle East and 12,000 BP in Europe during a wide time period, or broader spectrum. During this time, many plants and animals were hunted, gathered, collected, caught, and fished. ...more on Wikipedia about "Broad Spectrum Revolution"
Business action on climate change includes a range of activities relating to combatting global warming, and to influencing political decisions on global-warming-related regulation, such as the Kyoto Protocol. Major corporations have played and to some extent continue to play a significant role in the politics of global warming, especially in the United States, through lobbying of government and funding of global warming skeptics. Business also plays a key role in the mitigation of global warming, through decisions to invest in researching and implementing new energy technologies and energy efficiency measures. ...more on Wikipedia about "Business action on climate change"
The Callendar effect is a name for the effect of combustion-produced carbon dioxide on the global climate. It is therefore a special case of the greenhouse effect. The size of the Callendar effect is a controversy in global warming. ...more on Wikipedia about "Callendar effect"
The Campaign against Climate Change (variously abbreviated to CCC or CaCC) is a UK-based pressure group that aims to raise public awareness of anthropogenic climate change through mobilising mass demonstrations. Founded in 2001 in response to President Bush's rejection of the Kyoto protocol, the organisation saw a steady increase in attendance on marches, before a sudden take-off of interest between October - December 2005. An estimated 10,000 people attended its most recent rally in London, on December 3rd, 2005, making this easily the biggest demonstration on climate change in the UK to date. ...more on Wikipedia about "Campaign against Climate Change"
A carbon audit regime is an effective means of accounting for greenhouse gas control efforts. It establishes that the claimed reductions in emissions, or carbon sequestration, has actually occurred and is stable. ...more on Wikipedia about "Carbon audit regime"
Carbon credits as defined by Kyoto Protocol are one metric ton of carbon emitted by the burning of fossil fuels. ...more on Wikipedia about "Carbon credit"
A carbon dioxide sink or CO2 sink is a carbon reservoir that is increasing in size, and is the opposite of a carbon "source". The main sinks are the oceans and growing vegetation. The concept has become more widely known through its application by the Kyoto Protocol. ...more on Wikipedia about "Carbon dioxide sink"
Carbon emissions trading involves the trading of permits to emit carbon dioxide (and other greenhouse gases, calculated in tonnes of carbon dioxide equivalent, tCO2e). It is one of the ways countries can meet their obligations under the Kyoto Protocol to reduce emissions and thereby mitigate global warming. ...more on Wikipedia about "Carbon emissions trading" www.shortopedia.com - Go in quickly. shortopedia
A carbon offset is a reduction in carbon dioxide emissions from a third party, aimed at cancelling out (offsetting) the emissions arising from a particular activity. The aim is to reduce greenhouse gas emissions and thereby combat global warming. ...more on Wikipedia about "Carbon offset"
A carbon tax is a tax on energy sources which emit carbon dioxide into the atmosphere. It is an example of a pollution tax, which has been proposed by economists as preferable because it taxes a "bad" rather than a "good" (such as income). ...more on Wikipedia about "Carbon tax"
The Carteret Islands (also known as Tulun or Kilinailau Islands/Atoll), Tulun, Jangaini, Yecola, Yava and Puli are part of Papua New Guinea located 62 miles northeast of Bougainville in the South Pacific at 4°45'S, 155°24'E. The islands are a scattering of low lying atolls in a horseshoe shape stretching around 30 kilometers in north-south direction, named after the British navigator Philip Carteret who discovered them in the sloop Swallow in 1767. As of 2005 about one thousand people live on the islands. Tulun is the most significant island with partial (but rapidly dying due to saltwater introgression) tree cover, the others being small islets in the lagoon. ...more on Wikipedia about "Carteret Islands"

Clean coal is coal chemically washed of minerals and impurities, sometimes gasified, burned and the resulting flue gases treated with steam and reburned so as to make the carbon dioxide in the flue gas economically recoverable. The carbon dioxide will then be sequestered by some means (several are being explored - see Carbon dioxide sink). ...more on Wikipedia about "Clean coal"
The Clean Development Mechanism (CDM) is an arrangement under the Kyoto Protocol allowing industrialised countries with a greenhouse gas reduction commitment (so-called Annex 1 countries) to invest in emission reducing projects in developing countries as an alternative to what is generally considered more costly emission reductions in their own countries. ...more on Wikipedia about "Clean Development Mechanism" http://www.shortopedia.com - now!
Climate change refers to the variation in the Earth's global climate or regional climates over time. It describes changes in the variability or average state of the atmosphere - or average weather - over time scales ranging from decades to millions of years. These changes may come from internal processes, be driven by external forces or, most recently, be caused by human activities. ...more on Wikipedia about "Climate change"
Climate models use quantitative methods to simulate the interactions of the atmosphere, oceans, land surface, and ice. They are used for a variety of purposes from study of the dynamics of the weather and climate system to projections of future climate. ...more on Wikipedia about "Climate model"
In IPCC reports, equilibrium climate sensitivity refers to the equilibrium change in global mean surface temperature following a doubling of the atmospheric (equivalent) CO2 concentration. This value is estimated, by the IPCC TAR, to be "likely to be in the range of 1.5 to 4.5°C" ** . More generally, equilibrium climate sensitivity refers to the equilibrium change in surface air temperature following a unit change in radiative forcing (°C/Wm-2). In practice, the evaluation of the equilibrium climate sensitivity requires very long simulations with coupled global climate models. ...more on Wikipedia about "Climate sensitivity"
A climate surprise is defined by the IPCC as a rapid, non-linear response of the climatic system to anthropogenic climate forcing ( global warming). Climate surprises are low-probability, high-consequence extreme events, such as a collapse of the "conveyor belt" thermohaline circulation in the North Atlantic Ocean or rapid deglaciation of polar ice sheets. Because the global climate is made up of a number of complex subsystems which interact in complex and chaotic ways, climate change may lead to relatively few changes up to a tipping point, beyond which the system may tip into a new equilibrium. ...more on Wikipedia about "Climate surprise"
