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. ...
Words are never enough Words are not enough. I know that. But I want to start by saying how deeply disappointed and sorry I am for the activity undertaken in the name of Greenpeace at the Nazca lines in Peru last week during the climate talks.The place chosen for holding a banner showed a regrettable disregard for the culture of Peru and the importance of not going to fragile and culturally important sites without authorisation. Greenpeace International’s Executive Director, Kumi Naidoo, has this week met with the Peruvian Minister of Culture, who is responsible for the site, to offer an apology. Kumi has assured the Minister that we will fully participate in any investigation into the activity.I agree wholeheartedly with Kumi when he says: “This is against Greenpeace policy. It’s against our values. And it just shouldn’t have happened. Internally in Greenpeace I am committed to having a fast investigation to understand who took the decision, how it was taken and hold the people responsible accountab
Shape-shifting may help some species cope with climate change ScienceDaily: Researchers have found that a Rocky Mountain mustard plant alters its physical appearance and flowering time in response to different environmental conditions, suggesting some species can quickly shape-shift to cope with climate change without having to migrate or evolve. The findings appear in the journal Global Change Biology. The study was conducted by researchers from Dartmouth College and the University of South Carolina at the Rocky Mountain Biological Laboratory. Scientists studying climate...
Global warming will cut wheat yields, research shows Guardian: Global wheat yields are likely to fall significantly as climate change takes hold, new research has shown .
The researchers found that wheat production would fall by 6% for every 1C increase in temperatures. The world is now nearly certain to warm by up to 2C compared with pre-industrial levels, with political efforts concentrated on holding the potential temperature rise to no higher than that limit. But some analyses suggest that if greenhouse gas emissions continue to grow at current rates...
Greenpeace apologises to the people of Peru for Nazca activity 11 December, 2014
Lima, Peru, - Greenpeace releases the following apology about the Nazca Lines protest on
Without reservation Greenpeace
apologises to the people of Peru for the offence caused by our recent activity
laying a message of hope at the site of the historic Nazca Lines. We are deeply

We fully understand that this
looks bad. Rather than relay an urgent message of hope and possibility to the
leaders gathering at the Lima UN climate talks, we came across as careless and
We have now met with the
