Toronto Conference On The Changing Atmosphere
At the Toronto Conference on the Changing Atmosphere: Implications for Global Security, hosted by Canada in Toronto, Ontario, starting on 27 to 30 June 1988, the 300 participants—including policy makers, international scientists, non-governmental and governmental organizations, and United Nations organizations—issued a warning at the conclusion of the conference that humans had unintentionally triggered uncontrolled changes to the atmosphere that if left unchecked could ultimately lead to "consequences could be second only to a global nuclear war." The Toronto Conference took place in the same week that James Hansen, who served as director of National Aeronautics and Space Administration, NASA's Manhattan-based Goddard Institute for Space Studies (GISS) from 1981 to 2013, had cautioned in his 23 June 1988 testimony before the United States Senate Committee on Energy and Natural Resources, that it was 99% certain that the global "warming trend was not a natural variation" but was ...

Canadian Meteorological And Oceanographic Society
The Canadian Meteorological and Oceanographic Society (CMOS; french: Société canadienne de météorologie et d'océanographie) is the national society of individuals and organisations dedicated to advancing atmospheric and oceanic sciences and related environmental disciplines in Canada. CMOS was officially created in 1967 as the Canadian Meteorological Society, and adopted its present name in 1977, following an invitation by the Canadian Meteorological Society to the oceanographic community in Canada to join the Society. However, CMOS has a rich history dating back to 1939 when it was known as the Canadian Branch of the Royal Meteorological Society. In 2007, CMOS issued a position statement on global warming: :CMOS endorses the process of periodic climate science assessment carried out by the Intergovernmental Panel on Climate Change and supports the conclusion, in its Third Assessment Report, which states that the balance of evidence suggests a discernible human influence on g ...

Environment (biophysical)
A biophysical environment is a biotic and abiotic surrounding of an organism or population, and consequently includes the factors that have an influence in their survival, development, and evolution. A biophysical environment can vary in scale from microscopic to global in extent. It can also be subdivided according to its attributes. Examples include the marine environment, the atmospheric environment and the terrestrial environment. The number of biophysical environments is countless, given that each living organism has its own environment. The term ''environment'' can refer to a singular global environment in relation to humanity, or a local biophysical environment, e.g. the UK's Environment Agency. Life-environment interaction All life that has survived must have adapted to the conditions of its environment. Temperature, light, humidity, soil nutrients, etc., all influence the species within an environment. However, life in turn modifies, in various forms, its conditions. ...

It's A Matter Of Survival
''It's a Matter of Survival'' is a 1990 book by Anita Gordon and David Suzuki. Written for the general reader, the book looks ahead 50 years and explores the condition of human society and the environment. Suggestions are given about how to improve the future. The book originated as a radio series aired in 1989 by the Canadian Broadcasting Corporation. Overview In the series and the book, described how the "first global scientific consensus" that the world was "entering an era of unprecedented climate change" had emerged in the June 1988 international Toronto Conference on the Changing Atmosphere chaired by Stephen Lewis, and with 300 scientists from around the world in attendance. On the webpage of the David Suzuki Foundation—a non-profit organization environmental organization headquartered in Vancouver, British Columbia, Canada, that he co-founded in 1991, Suzuki said that the response to the CBC radio show was the catalyst for the establishment of the Foundation.

Canadian Broadcasting Corporation
The Canadian Broadcasting Corporation (french: Société Radio-Canada), branded as CBC/Radio-Canada, is a Canadian public broadcaster for both radio and television. It is a federal Crown corporation that receives funding from the government. The English- and French-language service units of the corporation are commonly known as CBC and Radio-Canada, respectively. Although some local stations in Canada predate the CBC's founding, CBC is the oldest existing broadcasting network in Canada. The CBC was established on November 2, 1936. The CBC operates four terrestrial radio networks: The English-language CBC Radio One and CBC Music, and the French-language Ici Radio-Canada Première and Ici Musique. (International radio service Radio Canada International historically transmitted via shortwave radio, but since 2012 its content is only available as podcasts on its website.) The CBC also operates two terrestrial television networks, the English-language CBC Television and the Frenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear War
Nuclear warfare, also known as atomic warfare, is a theoretical military conflict or prepared political strategy that deploys nuclear weaponry. Nuclear weapons are weapons of mass destruction; in contrast to conventional warfare, nuclear warfare can produce destruction in a much shorter time and can have a long-lasting radiological result. A major nuclear exchange would likely have long-term effects, primarily from the fallout released, and could also lead to secondary effects, such as "nuclear winter", nuclear famine and societal collapse. A global thermonuclear war with Cold War-era stockpiles, or even with the current smaller stockpiles, may lead to various scenarios including the extinction of the human race. To date, the only use of nuclear weapons in armed conflict occurred in 1945 with the American atomic bombings of Hiroshima and Nagasaki. On August 6, 1945, a uranium gun-type device (code name "Little Boy") was detonated over the Japanese city of Hiroshima. Thre ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

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 ...

Ozone Depletion
Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone (the ozone layer) around Earth's polar regions. The latter phenomenon is referred to as the ozone hole. There are also springtime polar tropospheric ozone depletion events in addition to these stratospheric events. The main causes of ozone depletion and the ozone hole are manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS). These compounds are transported into the stratosphere by turbulent mixing after being emitted from the surface, mixing much faster than the molecules can settle. Once in the stratosphere, they release atoms from the halogen group through photodissociation, which ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acid Rain
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulphur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, freshwaters, soils, microbes, insects and aquatic life-forms. In ecosystems, persistent acid rain reduces tree bark durability, leaving flora more susceptible to environmental stressors such as drought, heat/cold and pest infestation. Acid rain is also capable of detrimenting soil composition by stripping it of nutrients such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
