Callendar Effect
Guy Stewart Callendar (; 9 February 1898 – 3 October 1964) was an English steam engineer and inventor. His main contribution to human knowledge was developing the theory that linked rising carbon dioxide concentrations in the atmosphere to global temperature. In 1938, he was the first to show that the land temperature of Earth had risen over the previous 50 years. This theory, earlier proposed by Svante Arrhenius,American Institute of PhysicsThe Discovery of Global Warming: The Carbon Dioxide Greenhouse Effect, February 2014 (accessed 13 November 2014) has been called the Callendar effect. Callendar thought this warming would be beneficial, delaying a "return of the deadly glaciers." Early life, family and education Callendar was born in Montreal in 1898, where his father, Hugh Longbourne Callendar, was Professor of Physics at McGill College (now McGill University). An expert in thermodynamics, Hugh Callendar returned to the United Kingdom with his family upon being appointed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montreal
Montreal is the List of towns in Quebec, largest city in the Provinces and territories of Canada, province of Quebec, the List of the largest municipalities in Canada by population, second-largest in Canada, and the List of North American cities by population, ninth-largest in North America. It was founded in 1642 as ''Fort Ville-Marie, Ville-Marie'', or "City of Mary", and is now named after Mount Royal, the triple-peaked mountain around which the early settlement was built.

British Meteorological Society
The Royal Meteorological Society is an organization that promotes academic and public engagement in weather and climate science. Fellows of the Society must possess relevant qualifications, but Members can be lay enthusiasts. It publishes various journals, including the ''Quarterly Journal of the Royal Meteorological Society''. The chief executive officer is Liz Bentley. Constitution The Royal Meteorological Society traces its origins back to 3 April 1850 when the British Meteorological Society was formed as "a society the objects of which should be the advancement and extension of meteorological science by determining the laws of climate and of meteorological phenomena in general". Along with nine others, including James Glaisher, John Drew, Edward Joseph Lowe, The Revd Joseph Bancroft Reade, and Samuel Charles Whitbread, Dr John Lee, an astronomer, of Hartwell House, near Aylesbury, Buckinghamshire founded in the library of his house the British Meteorological Society, wh ...

Climate Sensitivity
Climate sensitivity is a key measure in climate science and describes how much Earth's surface will warm for a doubling in the atmospheric carbon dioxide () concentration. Its formal definition is: "The change in the surface temperature in response to a change in the atmospheric carbon dioxide (CO2) concentration or other radiative forcing."IPCC, 2021Annex VII: Glossary atthews, J.B.R., V.

Charles Keeling
Charles David Keeling (April 20, 1928June 20, 2005) was an American scientist whose recording of carbon dioxide at the Mauna Loa Observatory confirmed Svante Arrhenius's proposition (1896) of the possibility of anthropogenic contribution to the greenhouse effect and global warming, by documenting the steadily rising carbon dioxide levels. The Keeling Curve measures the progressive buildup of carbon dioxide, a greenhouse gas, in the atmosphere. Early life and early career Keeling was born in Scranton, Pennsylvania, to Ralph Keeling and Grace L Keeling (née Sherberne). His father, an investment banker, excited interests of astronomy in a 5-year-old Charles, while his mother instilled a lifelong love of music. He graduated with a degree in chemistry from the University of Illinois in 1948. Charles Keeling earned a PhD in chemistry from Northwestern University in 1953 under Malcolm Dole, a polymer chemist. Most of Dole's graduates were going straight into the oil industry; Keeling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbert Plass
Gilbert Norman Plass (March 22, 1920 – March 1, 2004) was a Canadian physicist who in the 1950s made predictions about the increase in global atmospheric carbon dioxide () levels in the 20th century and its effect on the average temperature of the planet that closely match measurements reported half a century later.Gilbert N.

Human Impact On The Environment
Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society (as in the built environment) is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, neoliberal economic policies and rapid economic growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species. The term ''anthropogenic'' designates an effect or object resulting from h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infra-red Radiation
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Warming
Present-day climate change includes both global warming—the ongoing increase in global average temperature—and its wider 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 temperatures is driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, deforestation, and some agricultural and industrial practices release greenhouse gases. These gases absorb some of the heat that the Earth radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, has increased in concentration by about 50% since the pre-industrial era to levels not seen for millions of years. Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has c ...

Nils Gustaf Ekholm
Nils Gustaf Ekholm (9 October 1848 – 5 April 1923) was a Swedish meteorologist who led a Swedish geophysical expedition to Spitsbergen in 1882–1883. Biography Ekholm was born in Smedjebacken in Dalarna, son of a pharmacist. Having completed his '' mogenhetsexamen'' in 1868, he enrolled at the University of Uppsala in September 1869, and graduated with a Candidate of Philosophy degree in 1876, completing a Licentiate degree in 1887 and a Ph.D. in 1888. He was a student of Robert Rubenson and Hugo Hildebrand Hildebrandsson. He worked at the Meteorological department at Uppsala University from 1876 until 1881, and again, after returning from his Spitsbergen expedition, 1884–1890, and was docent of meteorology at the university 1888–1892. From 1890 he worked as an assistant at the Swedish Meteorological Institute in Stockholm (one of the predecessor institutions of the current Swedish Meteorological and Hydrological Institute, SMHI, now located in Norrköping). He became pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
