Climate change is altering weather patterns, causing sea level rises and increasing the frequency and intensity of extreme weather events such as flash floods. These reduce harvest yields which lead to food shortages and price rises.
The UK, with 1% of the world’s population, produces 2.3% of the world’s CO2 and we use more than our fair share of global resources.
There is time to avert the worst but we need to act now to significantly reduce our carbon footprint.
The Royal Society | Climate Change Controversies
The Royal Society has produced this overview of the current state of scientific understanding of climate change to help non-experts better understand some of the debates in this complex area of science.
This is not intended to provide exhaustive answers to every contentious argument that has been put forward by those who seek to distort and undermine the science of climate change and deny the seriousness of the potential consequences of global warming. Instead, the Society – as the UK’s national academy of science – responds here to eight key arguments that are currently in circulation by setting out, in simple terms, where the weight of scientific evidence lies.
Here are three video on climate change that I think are well worth watching.
The first is from 350.org It sums up the basics of the 350 movement–the science, the creativity, and most importantly, the International Day of Climate Action on 24 October, 2009. Click here to find out more.
Running time just over 2 minutes.
The second is from photographer James Balog’s latest work. A network of time-lapse cameras recording glaciers receding at an alarming rate, some of the most vivid evidence yet of climate change. http://www.extremeicesurvey.org/
Running time just over 19 minutes.
The thrid, is the revised version of video that has had over 7 million views “A Rational Response to the Climate Change Debate” by Greg Craven. He’s a science teacher who puts an argument that you don’t need to believe anyone, but can still decide with confidence what we should do.
Running time just under 10 minutes.
