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. ...
Norway's offshore drilling puts Arctic Ocean at risk All rights reserved. Credit: Greenpeace
As Norway pushes further into the Arctic with offshore oil drilling, the corresponding environmental risks have increased significantly.
The Barents Sea is one of the richest, most unique marine ecosystems in the world, with remarkable concentrations of seabirds, marine mammals, fish, and other marine life. The short-term energy potential here is truly not worth the long-term environmental risk from offshore drilling.
This summer, Statoil has drilled three exploratory wells in the northern Barents Sea, about 300 km southeast of Svalbard. A fourth well is being drilled at present, together with the Russian oil company Rosneft. So far these exploratory wells haven ́t reported significant hydrocarbons, but the company plans to continue exploratory drilling
Doping drug EPO protects brains of premature babies Giving erythropoietin (EPO) – used illegally by endurance athletes – to babies immediately after birth significantly reduces brain damage, according to scientists in Geneva. Premature babies are far more at risk than infants born at term of developing brain damage resulting in neurodevelopmental delay that may persist throughout their lives. A team of specialists in infant brain imaging from the Faculty of Medicine at the University of Geneva and the University Hospital of Geneva has shown that administering three doses of EPO – a hormone that stimulates the formation of red blood cells – immediately after birth significantly lowers brain damage in babies. The results were published in the Journal of American Medical Association on Tuesday. Nearly 400,000 children are born in Europe every year before the 32nd week of pregnancy and 2.6 million worldwide, according to the World Health Organization, including around 80 at the University Hospital of Geneva. There ... S
On the Germany-Poland border, thousands are protesting a huge coal mine All rights reserved. Credit: Jörg Gläscher / Greenpeace

Lignite mining near Jaenschwalde, Germany
Today, several thousand people have joined hands across the German-Polish border, forming a human chain that passes through towns and villages that stand on the front-line of the fight against climate change.
This is an act of solidarity with the more than 6,000 people who will be forced from their homes by massive new coal mines proposed by utilities Vattenfall and PGE. It also marks a line in the sand for all those who realise that coal has no future in our energy system if we are serious about tackling climate change.
The two proposed mines would each be the size of Manhattan and target a rich seam of lignite, a type of coal that was recently
Norway ends seismic testing after pressure by environmental organisations 21 August, 2014
Seismic testing in the Barents
Sea, commissioned by the Norwegian Petroleum Directorate, has been stopped four
days after Greenpeace exposed the testing programme in the Norwegian TV2 news.
The Greenpeace ship Esperanza approached the research vessel Artemis
Atlantic on Wednesday when it changed course towards Hammerfest.
Seismic mapping is the very first
step of oil exploration. An air gun shoots sound pulses that penetrate the
seafloor and the reflected sound waves are then recorded by sensors dragged on
long cables after the ship. The data collected is used to map the seafloor so
that oil companies can look for positions where they can drill for oil.
Sound travels extremely well
under water and the noises from seismic vessels have been recorded thousands of
kilometres away. Marine mammals depend on sounds to
navigate and feed and they are incredibly vulnerable to these loud
