Global warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide. GWP is 1 for CO2. For other gases it depends on the gas and the time frame.
Biodiversity is the biological variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth, and is richer in the tropics. These tropical forest ecosystems cover less than ten percent of earth's surface, and contain about ninety percent of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural processes that sustain life.
Globalization, or globalisation, is the process of interaction and integration among people, companies, and governments worldwide. Globalization has accelerated since the 18th century due to advances in transportation and communication 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 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 the country of Russia into the Group of Seven, or G7, and returned to its previous name after Russia was removed in 2014.

A global city, also called a power city, world city, alpha city or world center, is a city which is a primary node in the global economic network. The concept comes from geography and urban studies, and the idea that globalization is created and furthered in strategic geographic locales according to a hierarchy of importance to the operation of the global system of finance and trade.
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 inter-governmental political forum consisting of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States. Its members are the world's largest IMF advanced economies and wealthiest liberal democracies; the group is officially organized around shared values of pluralism and representative government. As of 2020, the G7 nations account for a little over 50 percent of global net wealth, 32 to 46 percent of global gross domestic product, and about 770 million people or 10 percent of the world's population. Most members are great powers in global affairs and maintain mutually close economic, military, and diplomatic 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 Twenty 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.
Global citizenship is the idea that one's identity transcends geography or political borders and that responsibilities or rights are derived from membership in a broader class: "humanity". This does not mean that such a person denounces or waives their nationality or other, more local identities, but that such identities are given "second place" to their membership in a global community. Extended, the idea leads to questions about the state of global society in the age of globalization.
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.
Contemporary climate change includes both the global warming caused by humans, and its impacts on Earth's weather patterns. There have been previous periods of climate change, but the current changes are more rapid than any known events in Earth's history. The main cause is the emission of greenhouse gases, mostly carbon dioxide and methane. Burning fossil fuels for energy use creates most of these emissions. Agriculture, steelmaking, cement production, and forest loss are additional sources. Temperature rise is also affected by climate feedbacks such as the loss of sunlight-reflecting snow cover, and the release of carbon dioxide from drought-stricken forests. Collectively, these amplify global warming.
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, causing climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest polluters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50%.
In telecommunications, 5G is the fifth generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones. 5G networks are predicted to have more than 1.7 billion subscribers worldwide by 2025, according to the GSM Association. Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. The main advantage of the new networks is that they will have greater bandwidth, giving higher download speeds, eventually up to 10 gigabits per second (Gbit/s). In addition to 5G being faster than existing networks, 5G can connect more different devices, and even if people are in crowded areas, the servers will be more unified, improving the quality of Internet services. Due to the increased bandwidth, it is expected the networks will increasingly be used as general internet service providers (ISPs) for laptops and desktop computers, competing with existing ISPs such as cable internet, and also will make possible new applications in internet-of-things (IoT) and machine-to-machine areas. 4G cellphones are not able to use the new networks, which require 5G-enabled wireless devices.
