This is a shocking video from Dan Mace. Old Navy in America throw away an estimated 5 million plastic hangers each week. They don't reuse the hangers after someone buys the clothes. That's 6350 tonnes of plastic hangers in landfills each year.
Researchers at UCLA have produced a prototype energy unit that takes advantage of radiative sky cooling to generate electricity at night. As heat is radiated from objects facing the sky at night, a thermoelectric generator can be used to generate electricity from the temperature difference, in this case 25 milliwatts per square metre using equipment costing $30.
Information Is Beautiful have published a fantastic, informative and very important visualisation of the breakdown of the 51.8 Gigatonnes of CO2e emission we produce each year. The visualiastion also lays out the amount of reduction needed in each category to half the emissions by 2013 and reach net zero by 2050.
The Guardian have released a flight carbon calculator, allowing you to select your starting and destination airports to see how much kilograms of CO2 emmissions are released per passenger on that return flight. it also shows you how many countries emit less CO2 per person per year compared to that flight. Aviation is responsible for 2% of global emissions and are set to at least double by 2050 :-(
This is the most important book you will read. It's a gut punch followed by a loving hug and sense of empowerment. Tell everyone, Act Now. Read this book, please!

Climate scientist at University of Reading Ed Hawkins has created the #ShowYourStripes datavis site, which generates an image of temperature increases for every country for the last 100 years or so. Each stripe averages the temperature over a year and is built from the Berkely Earth Temperature Dataset. (H/T to Mikael for sharing this)
