National and international science academies and scientific societies have assessed current scientific opinion on global warming.These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change.. Some scientific bodies have recommended specific policies to governments, and science can play a role in informing an …

Carbon dioxide in Earth's atmosphere is a trace gas, having a global average concentration of 421 ppm as at May 2022. The concentration is expressed as "parts per million" (ppm, on a molar basis).This increase of CO 2 in Earth's atmosphere has resulted in global warming and ocean acidification. Carbon dioxide (CO 2) in Earth's atmosphere is an integral part of the carbon …

Units. Acceleration has the dimensions of velocity (L/T) divided by time, i.e. L T −2.The SI unit of acceleration is the metre per second squared (m s −2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.. Other forms. An object moving in a circular motion—such as a satellite orbiting the Earth—is accelerating due ...

The extinction risk of climate change is the risk of species becoming extinct due to the effects of climate change.Climate change is the long-term conversion of temperature and average weather patterns. Currently, 19% of species on the IUCN Red List of Threatened Species are already being impacted by climate change. Many studies have been conducted on how climate …

Definition. Social change may not refer to the notion of social progress or sociocultural evolution, the philosophical idea that society moves forward by evolutionary means.It may refer to a paradigmatic change in the socio-economic structure, for instance the transition from feudalism to capitalism, or hypothetical future transition to some form of post-capitalism.

Technological change (TC) or technological development is the overall process of invention, innovation and diffusion of technology or processes. In essence, technological change covers the invention of technologies (including processes) and their commercialization or release as open source via research and development (producing emerging technologies), the continual …

The Greenland ice sheet (Danish: Grønlands indlandsis, Greenlandic: Sermersuaq) is a vast body of ice covering 1,710,000 square kilometres (660,000 sq mi), roughly near 80% of the surface of Greenland.It is sometimes referred to as an ice cap, or under the term inland ice, or its Danish equivalent, indlandsis.An acronym, GIS, is frequently used in the scientific literature.

Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized. These technologies are generally new but also include older technologies finding new applications. Emerging technologies are often perceived as capable of changing the status quo.. Emerging technologies are characterized by radical novelty (in application even …

In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans …

Un eBook, chiamato anche e-book, eBook, libro elettronico o libro digitale, è un libro in formato digitale, apribile mediante computer e dispositivi mobili (come smartphone, tablet PC).La sua nascita è da ricondurre alla comparsa di apparecchi dedicati alla sua lettura, gli eReader (o e-reader: "lettore di e-book").
