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. ...
Government-commissioned report shows 3rd runway may break air quality laws 2 February, 2017
A third runway at Heathrow may delay compliance with air quality laws for years, according to documents published by the government today.
The admission puts the airport expansion in jeopardy because the government has said planning consent will not be granted if it cannot be delivered within current air quality and climate change laws.The independent impact assessment commissioned by the government warns that building a third runway could delay compliance with air quality laws. It states that there is "a risk that the option will delay compliance" with air pollution limits.The assessment, carried out by an external consultancy for the Department for Transport, goes on claiming that compliance with the law won't be a problem after 2030. Yet the document also reveals that this prediction is based on the assumption that real-world car emissions
A government scheme for funding renewables is about to be sold off to a firm that backs fracking. We must stop this by. Credit: Left: Greenpeace / Right: Wikipedia
If you're on Greenpeace's email list, chances are you'll have just received an email about the Green Investment Bank - a government body that is currently being privatised. If the sale goes through as it stands, it could have devastating consequences on the UK renewable energy industry.
That's why we've launched an urgent campaign to pressure MPs to speak out against the sale. Here's the email in case you missed. You can take part by emailing your MP here.
Does this sound like a dodgy deal or what?
A little-known government body that channels billions of pounds into green projects and renewable power is on the verge of being privatised and sold off -- to a firm that backs fracking and coal!
A group of MPs have already spoken out against the government’s sell-off plans. With pressure mounting by the day, a backlash from mor
How much space would need to be covered by solar panels to power every home in the UK? Have you ever wondered - how much space would need to be covered by solar panels, if we tried to produce the amount of power used by every home in the UK? Well, here's the answer...
0.3% of the UK. That's about 827 km². Or, to put it another way, an area about half the size of Greater London.
A Greenpeace video (the one at the top of this page) breaks down what that'd look like if all the solar panels were in the same place. If you've watched it and now you're wondering how we arrived at the final numbers, this blog explains how the calculation was made.
To start with, we worked out how much electricity we’d need to produce. Based on government data from 2015, we know that UK homes consumed about 108.2 billion kWh of electricity over the course of the year.
Next we calculated approximately how much electricity an average solar PV installation produces. To simplify things, we looked at how much power would be produced by south-facing PV panels only. Using data from The En
Public names Zurich elephant ‘Ruwani' The female elephant born in Zurich Zoo on February 25 will be called Ruwani. The name received 8,263 votes in an online poll, Zurich Zoo revealed on Monday. The two other options, Rishu and Reshani, picked up 3,147 and 1,894 votes respectively. (Zurich Zoo, swissinfo.ch) All three names have a connection with Sri Lanka, home of one of the calf’s grandmothers. Ruwani means “like a precious stone, highly valuable”. In a separate poll, almost two-thirds of swissinfo.ch readers went for Rishu. What do you think? Let us know.
