Climate change is any long-term significant change in the “average weather” that a given region experiences. Average weather may include average temperature, precipitation and wind patterns. It involves changes in the variability or average state of the atmosphere over durations ranging from decades to millions of years. These changes can be caused by dynamic processes on Earth, external forces including variations in sunlight intensity, and more recently by human activities.In recent usage, especially in the context of environmental policy, the term "climate change" often refers to changes in modern climate (see global warming). For information on temperature measurements over various periods, and the data sources available, see temperature record. For attribution of climate ...
There might be feedbacks in the climate system that we aren't aware of yet.
The amount of carbon in the oceans and atmosphere changes suddenly and dramatically. The oceans are acidified and significant extinctions result. On land, global temperatures increase anywhere from five to nine degrees Celsius, causing widespread habitat disruptions. Despite the sudden onset of the event, its impact lingers for 100 thousand years.
his might sound like a worst-case situation for the current anthropogenic influences on climate, but it's actually an historic event that the public is generally unaware ...
There is "absolutely no scientifically proven basis for the premise that man can affect what the climate does" is absurd. Our libraries are full of carefully compiled and critically reviewed scientific research that makes it clear that global warming is real, is caused by human activity and is significantly and rapidly changing the world's climate.The research conclusions of dozens of respected scientific organizations such as the American Geophysical Union, the American Physical Society, the National Academies of Science and the American Meteorological Society are easily available online.Our ...
Presentation of scary stories about global warming in the popular media makes us unnecessarily frightened. Even worse, it terrifies our kids.Al Gore famously depicted how a sea-level rise of 20 feet (six meters) would almost completely flood Florida, New York, Holland, Bangladesh, and Shanghai, even though the United Nations estimates that sea levels will rise 20 times less than that, and do no such thing. When confronted with these exaggerations, some of us say that they are for a good cause, and surely there is no harm done if the result is that we focus even more on tackling climate change. ...
Lib Dem coal pledge welcome but subsidies must be scrapped 7 October, 2014
Greenpeace has welcomed today’s announcement by the energy secretary, Ed Davey, that the Liberal Democrats will put plans to phase out old coal plants by 2025 at the centre of any future coalition programme.
environmental group has warned that Ed Davey will end up sabotaging his own
party’s efforts if his department allows energy firms to bid for
multi-billion-pound subsidies that could be used to refurbish and extend the
lifespan of polluting coal plants.
on the announcement, Greenpeace UK energy campaigner Lawrence Carter
“The Lib Dems
must be given credit for being the first party to put a clear expiry date on
our polluting coal plants. Britain’s addiction to the dirtiest fossil fuel is
giving us more air pollution, climate change, and dependence on volatile
Professor documents climate-change effects in Greenland Stevens Point Journal: A professor from the University of Wisconsin-Stevens Point traveled with one of his former students to Greenland over the summer to study peregrine falcons and document changes in their lives caused by climate change.
Biology professor Bob Rosenfield traveled with alumna Maddie Hardin to Greenland for two weeks to document the ages of nestling peregrines, based on the development of their feathers, and compared the data to information collected in previous years. Rosenfield said he believes the...
Canada: New reports shed light Fording River pollution problems Globe and Mail: The Fording River seems to run through paradise in the wild Canadian Rocky Mountains, but Environment Canada experts say it is so heavily polluted that fish are hatching with terrible deformities and dying by the thousands.
Teck Coal Ltd. has long acknowledged their responsibility concerning a pollution problem in the Elk Valley, with the company spending $600-million over the next five years in an unprecedented effort to improve water quality.
But two Environment Canada reports prepared as...
Adapt to climate and cut emissions, say Brazil, South Africa, India and China Economic Times: The collective of the four advanced developing countries, BASIC, Brazil, South Africa, India and China, has stressed that the global effort to tackle climate change must focus on adapting to climate as well as reducing emissions. "Adaptation needs are driven by the extent of adverse effects of climate change, experienced both now and in the future," the BASIC said in the statement on Friday at the end of their two-consultation in Sun City, South Africa.Ahead of the negotiations to be held in Bonn...
