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. ...
Australia: We can't ignore climate change: Major General says Sunshine Coast Daily: CLIMATE change is a reality we ignore to our peril, the former chairman of the Queensland Reconstruction Authority will tell an innovative forum at the University of the Sunshine Coast today.
Major General Gary Wilson AO, who was chairman of the authority during the $7 billion reconstruction recovery program after Queensland's 2011 summer of floods and cyclone devastation, will head a leading panel that will address an invited audience drawn from community and service organisations.
The Swiss start-up tackling radiation threats Entrepreneurs have helped develop a new system designed to detect radiological threats, which is being tested at ports across Europe. (SRF ECO, swissinfo.ch) Monitors hidden inside a van can single out freight containing substances such as uranium, plutonium, or radiological components for "dirty bombs”. These are weapons that combine radioactive material with conventional explosives. The information gathered allows operators to exclude the possibility of a detected plutonium source being a “ready-to-go” nuclear weapon. The system is the first of its type in the world to combine fast and thermal neutron detection. The technologies were tested at CERN, the European Laboratory for Nuclear Research near Geneva. The MODES_SNM project – the result of pan-European research and development –unites specialists from a number of fields, ranging from customs to nuclear physics. It was funded by the European Commission and developed by a consortium that includes Swiss start-up A
How LEGO got awesome to #SaveTheArctic All rights reserved. Credit: Greenpeace
We did it! LEGO has dropped Shell
We did it! LEGO has dropped Shell
Today we got the awesome news: after a three-month campaign
supported by more than a million people worldwide, LEGO has announced it will
not renew its contract with Arctic destroyer Shell.
This is fantastic news for LEGO fans and Arctic defenders
everywhere. And it’s a huge blow to Shell’s strategy of partnering with beloved
brands to clean up its dirty image as an Arctic oil driller.
So how did we win this victory for the Arctic? Let’s take a
look back at the top five moments of our campaign:
1. The most viral video in Greenpeace history
A hot tub, a Game of Thrones character, a very sad polar
bear, and the most depressing version of the most upbeat song yo
Three-day Ebola quarantine judged ‘too short’ Swiss scientists studying patient data from the Ebola epidemic in Sierra Leone have concluded that a quarantine period of three days is too short to identify all cases. The team, led by Tanja Stadler from the Department of Biosystems Science and Engineering at the federal institute of technology ETH Zurich, analysed the DNA of 70 people who had fallen ill with Ebola in Sierra Leone in May and June. The researchers used software to establish a family tree of the virus. They thus obtained a reproduction rate for Ebola – the number of cases one case generates on average over the course of its infectious period in an otherwise uninfected population – of 2.18. Previous estimates of the reproduction rate had ranged from 1.2-8.2. “A big advantage of our method is that it takes into account unregistered cases and therefore the real measure of the epidemic can be calculated,” Stadler said in a statement on Wednesday. The researchers put the grey zone of non-reported ... Show mo
