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. ...
Shell’s dangerous Arctic drilling plans exposed through counter-advertising 13 November, 2014
Today Greenpeace launched a counter-advertising campaign in
response to Shell’s latest ad, which
portrays a girl reading a book in bed by lamp light, with the caption ‘let’s
keep the lights on when she’s your age’. A polar bear sits on her bedside
At 5am this morning, activists scaled the outside of a railway
bridge on York Road next to Waterloo station to attach a billboard, facing
Shell’s central London offices. As staff walked to work, they read the message
‘let’s keep the drills on, so the Arctic’s gone when she’s your age’. Two
activists remain attached to the outside walls of the bridge and they intend to
keep the billboard up until 1.30pm. See photos.
And more than 2,300 Greenpeace supporters donated to place a
counter-advert in the Metro, Independent and Telegraph today, with the headline
‘Shell’s Arctic drilling plans are the stuff of ni
Following Rosetta's progress from Bern swissinfo's Veronica DeVore was with scientists in Bern as they witnessed the first-ever landing of a robot on a comet. The scientists had led the development of the ROSINA sensor aboard the Rosetta spacecraft. -->November 13, 15:00 - Stability amid uncertainty More images are coming in detailing Philae’s landing yesterday. Scientists are now saying the craft touched down and bounced twice before coming to rest, perhaps travelling in open space between bounces for as much as two hours. The good news is Philae has come to a rest on the comet. The more troubling news, say scientists, is that it isn’t properly anchored and it’s in a pretty shady spot, meaning its solar panels won’t get nearly as much power as hoped. Originally, the plan was for Philae to get six or seven hours of sun per day – now it will get just 1.5. “We don’t know what this means for the near future,” researchers said in the latest ESA media briefing. They also said they need to be careful abou
Rosetta spacecraft phones home After almost three years of hibernation, the comet-chasing space probe Rosetta has woken up and sent a message to its creators at the European Space Agency, some 800 million kilometres (500 million miles) away. “Hello World” was the message received by scientists shortly after 7 p.m. Swiss time (1800 GMT) on Monday. “It was a little bit late, about half an hour or so, but if you sleep for 2 ½ years that’s understandable,” said Peter Wurz, a co-investigator on the Rosetta mission for the University of Bern. “It was really cold, and the spacecraft had to wake up,” he told swissinfo.ch. “It’s like us. When it's cold we take a little while to open our eyes.” Rosetta, which was put into conservation mode in 2011, is on the way to a rendez-vous with the comet 67P/Churyumov-Gerasimenko. The two are expected to meet up in the coming months. Rosetta will spend some time observing the comet, which measures about 4 kilometres in diameter, before dropping
Summer 2014 Saw Warmest Ocean Temperatures Ever Recorded Nature World: Summer 2014 saw the warmest ocean temperatures ever recorded, according to a new report, proving that global warming is not slowing down.
But many people, including scientists, did think at one point that global warming had indeed taken a break. Greenhouse gas levels may have increased drastically in recent years, hitting a record high in 2013, but overall global tempratures have actually barely risen in the last 16 years, according to a recent study published in the journal Nature Geoscience...
