The greenhouse effect occurs when greenhouse gases in a planet's atmosphere cause some of the heat radiated from the planet's surface to be trapped in the lower atmosphere. A planet is warmed by absorbing light from its host star and cooled by radiating energy into space. The warm surface of a planet emits infrared thermal radiation. Greenhouse gases absorb some of that radiation, reducing the amount of energy that escapes into space. This reduction in planetary cooling raises the planet's average surface temperature. Adding greenhouse gases to the atmosphere increases the warming effect.
Global warming potential (GWP) is a measure of how much infrared thermal radiation a greenhouse gas added to the atmosphere would absorb over a given time frame, as a multiple of the radiation that would be absorbed by the same mass of added carbon dioxide. GWP is 1 for CO2. For other gases it depends on the how strongly the gas absorbs infrared thermal radiation, how quickly the gas leaves the atmosphere, and the time frame being considered.
Globalization, or globalisation, is the process of interaction and integration among people, companies, and governments worldwide. The term globalization first appeared in the early 20th century, developed its current meaning some time in the second half of the 20th century, and came into popular use in the 1990s to describe the unprecedented international connectivity of the post-Cold War world. Its origins can be traced back to 18th and 19th centuries due to advances in transportation and communications technology. This increase in global interactions has caused a growth in international trade and the exchange of ideas, beliefs, and culture. Globalization is primarily an economic process of interaction and integration that is associated with social and cultural aspects. However, disputes and international diplomacy are also large parts of the history of globalization, and of modern globalization.
The Group of Eight (G8) was an inter-governmental political forum from 1997 until 2014. It had formed from incorporating Russia into the Group of Seven, or G7, and returned to its previous name after Russia was expelled in 2014.
The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, transpiration, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor. The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation.
A business jet, private jet or bizjet is a jet aircraft designed for transporting small groups of people, typically business executives and high-ranking associates. Business jets are generally designed for faster air travel and more personal comfort than commercial aircraft, and may be adapted for other roles, such as casualty evacuation or express parcel deliveries, and some are used by public bodies, government officials, VIPs or even the armed forces.
A global city, also known as a power city, world city, alpha city, or world center, is a city that serves as a primary node in the global economic network. The concept originates from geography and urban studies, based on the thesis that globalization has created a hierarchy of strategic geographic locations with varying degrees of influence over finance, trade, and culture worldwide. The global city represents the most complex and significant hub within the international system, characterized by links binding it to other cities that have direct, tangible effects on global socioeconomic affairs.
The Bombardier Global Express is a large cabin, 6,000 nmi / 11,100 km range business jet designed and manufactured by Bombardier Aviation . Announced in October 1991, it first flew on 13 October 1996, received its Canadian type certification on 31 July 1998 and entered service in July 1999. Initially powered by two BMW/Rolls-Royce BR710s, it shares its fuselage cross section with the Canadair Regional Jet and Challenger 600 with a new wing and tail. The shorter range Global 5000 is slightly smaller and the Global 6000 is updated and has been modified for military missions. The longer range Global 5500/6500 are powered by new Rolls-Royce Pearl engines with lower fuel burn and were unveiled in May 2018. The larger and stretched Global 7500/8000 have longer ranges.
The Group of Seven (G7) is an intergovernmental political forum consisting of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States; additionally, the European Union (EU) is a "non-enumerated member." It is organized around shared values of pluralism, liberal democracy, and representative government. As of 2020, G7 members are large IMF advanced economies and account for over half of global net wealth, 30 to 43 percent of global gross domestic product, and 10 percent of the world's population. Some members are great powers in global affairs and maintain mutually close political, economic, diplomatic, and military relations.
The NatureServe conservation status system, maintained and presented by NatureServe in cooperation with the Natural Heritage Network, was developed in the United States in the 1980s by The Nature Conservancy (TNC) as a means for ranking or categorizing the relative imperilment of species of plants, animals, or other organisms, as well as natural ecological communities, on the global, national or subnational levels. These designations are also referred to as NatureServe ranks, NatureServe statuses, or Natural Heritage ranks. While the Nature Conservancy is no longer substantially involved in the maintenance of these ranks, the name TNC ranks is still sometimes encountered for them.
The G20 or Group of 20 is an intergovernmental forum comprising 19 countries and the European Union (EU). It works to address major issues related to the global economy, such as international financial stability, climate change mitigation, and sustainable development.
internet Speech Audio Codec (iSAC) is a wideband speech codec, developed by Global IP Solutions (GIPS). It is suitable for VoIP applications and streaming audio. The encoded blocks have to be encapsulated in a suitable protocol for transport, e.g. RTP.
The Group of Eight + Five (G8+5) was an international group that consisted of the leaders of the heads of government from the G8 nations, plus the heads of government of the five leading emerging economies. In March 2014, Russia was cast out of the Group of 8 due to its involvement in the 2014 Crimea crisis in Ukraine, so the G8+5 in its original form is unlikely to reconvene with Russia present.
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases (GHGs). Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before.
The ocean is a body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water. The term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. Distinct names are used to identify five different areas of the ocean: Pacific, Atlantic, Indian, Southern, and Arctic. Seawater covers approximately 361,000,000 km2 (139,000,000 sq mi) of the planet. The ocean is the primary component of the Earth's hydrosphere, and thus essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir.
Madieae is a tribe of flowering plants in the family Asteraceae. It is sometimes considered a subtribe of Heliantheae. Notable species include the tarweeds of the Western United States as well as the silverswords of Hawaii.
