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. ...
4 stories of Indigenous Peoples’ struggle for climate justice Fracking, racism, powerful mining companies, colonialism, the oil industry – Indigenous People across the world are fighting so many things in the struggle for climate justice.From Canada to Honduras to Brazil to Finland, Indigenous Peoples face systematic oppression, government ambivalence and corporate greed - and with a changing climate their battles have gotten even bigger. When your life, existence and culture is threatened there’s no way to run away - speaking truth to power is the only way to live.There’s nobody better than Indigenous People themselves to tell you what it’s like to be at the forefront of Indigenous resistance. That’s why, in honour of Indigenous Peoples Day, I spoke to Indigenous People from across the world - here’s what they had to say about the struggles they face.Arnaldo Kabá Munduruku - General Chief – CaciqueDams in the Tapajos region of the Amazon could be about to force the Munduruku Indigenous People to leave their home against their
“May will need to make a choice between diesel cars or people’s lives” 18 July, 2016
in partnership with the Institute for Public Policy Research (IPPR), today
released Lethal and Illegal (1), new air pollution research based on modelling
from King’s College, that shows clean air will be a reality
only if diesel vehicles are phased out altogether. The paper will be presented
today at City Hall at an event attended by Deputy Mayor for Transport, Val
Shawcross, and representatives from the Royal College of Physicians and businesses.
New modelling based on transport emissions and
air pollution data undertaken by King’s College as part of this project reveals
that, even if London were to return to the lowest recorded level of diesel car
ownership in the UK (around 10% of the car fleet in 1995), it would still not
reach compliance with World Health Organisation guidelines and UK law by 2025.
Swiss court denies ‘late’ Russian bid to freeze track ban Two Russian track and field athletes have failed in a last-ditch bid to have their ban from the Olympics put on hold. Two-time Olympic pole vault gold medallist Yelena Isinbayeva and world 110-metre hurdles champion Sergei Shubenkov had applied to the Swiss Federal Court in Lausanne to delay application of an earlier ruling by the Court of Arbitration for Sport (CAS) – also in Lausanne – which upheld the Russian team’s ban from the Olympic track meet. Had they won, it could have allowed them to compete at the Rio de Janeiro Games. However, the court ruled on Monday that the two Russians had waited too long after the CAS ruling to file their request and that they had failed to demonstrate that they met the criteria of the International Olympic Committee (IOC) to compete in Rio. “The last hope to perform at the Olympic Games has disappeared,” Isinbayeva wrote on social media. Shubenkov, however, insisted he and Isinbayeva would fight on in court. “It doesn’t in any ...
Swiss scientists to analyse returned satellite On Tuesday, a retired European Space Agency research satellite called Eureca (European Retrievable Carrier) left the Lucerne Museum of Transport, where it had been on display, for the Swiss Federal Laboratories for Materials Science and Technology (EMPA) in Dübendorf. There, the satellite, which was launched into orbit on the Space Shuttle Atlantis on August 2, 1992, will be x-rayed by EMPA scientists. They are interested in discovering the effects of space travel – including cosmic rays, extreme temperatures, and vibrations – on Eureca’s component parts. Antonia Neels, head of EMPA’s Center for X-Ray Analytics, said in a statement that this is a unique experiment for the federal laboratory. The three-ton craft, which suffered damage in space, will be x-rayed from every angle. EMPA’s special x-ray unit uses high-energy radiation that produces very high-resolution images, and is the only tool that can x-ray the satellite as a single object. The operation should ...
