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. He was the first to demonstrate that the Earth's land temperature had increased over the previous 50 years in 1938. 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 ap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montreal
Montreal ( ; officially Montréal, ) is the List of the largest municipalities in Canada by population, second-most populous city in Canada and List of towns in Quebec, most populous city in the Provinces and territories of Canada, Canadian province of Quebec. Founded in 1642 as ''Fort Ville-Marie, Ville-Marie'', or "City of Mary", it is named after Mount Royal, the triple-peaked hill around which the early city of Ville-Marie is built. The city is centred on the Island of Montreal, which obtained its name from the same origin as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard. The city is east of the national capital Ottawa, and southwest of the provincial capital, Quebec City.

Climate Sensitivity
Climate sensitivity is a measure of how much Earth's surface will cool or warm after a specified factor causes a change in its climate system, such as how much it will warm for a doubling in the atmospheric carbon dioxide () concentration. In technical terms, climate sensitivity is the average change in global mean surface temperature in response to a radiative forcing, which drives a difference between Earth's incoming and outgoing energy. Climate sensitivity is a key measure in climate science, and a focus area for climate scientists, who want to understand the ultimate consequences of anthropogenic global warming. The Earth's surface warms as a direct consequence of increased atmospheric , as well as increased concentrations of other greenhouse gases such as nitrous oxide and methane. The increasing temperatures have secondary effects on the climate system, such as an increase in atmospheric water vapour, which is itself also a greenhouse gas. Scientists do not know exactly h ...

Charles Keeling
Charles David Keeling (April 20, 1928 – June 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; Kee ... [...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. Plass, James Rodger Fleming, and Gavin Schmidt"Carbon Dioxide and the Climate" ''American Scientist'', 98(1) 58-62. An abridged reprint of Plass's 1959 ''Scientific American'' paper with commentary by Fleming and Schmidt Biography Plass worked most of his life as a physicist in the United States.

Human Impact On The Environment
Human impact on the environment (or anthropogenic 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 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, 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 human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it w ...

Infra-red Radiation
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates 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 heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Global Warming
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 burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

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).
