Calculating your water footprint
February 10, 2014 11:01 AM - Robin Blackstone, ENN
Water scarcity affects 2.7 billion people worldwide for at least a month each year and in the same way that each of us has a carbon footprint, Professor Arjen Hoekstra of the University of Twente in the Netherlands posits that every person also has a "water footprint". Our water footprint is calculated by counting the amount of fresh water that we each use daily and the amount of water required to produce the goods and services that we consume. Due in large part to our monthly water bill, we recognize our daily fresh water use more than we do the amount of water that it takes to produce other foods and products that we consume. We more commonly think about water consumption in terms daily showers dishwasher and sprinkler usage or dripping spigots.
African Monsoon Project to Benefit Crops and Healthcare
February 10, 2014 09:06 AM - Nick Kennedy, SciDevNet
Researchers unraveling the complexities of the West African monsoon say they are set to bring major agricultural and health benefits to people in the region — despite setbacks caused by terrorist threats and wars in the Sahel region. The African Monsoon Multidisciplinary Analysis (AMMA) programme, a consortium of over 400 researchers from 30 countries that was started 14 years ago, has gathered a wealth of new data about the West African monsoon from across the Sahel, and is now inspiring similar projects elsewhere in Africa.
Extreme Winter Weather Puts Strain on Power Systems, Lets Wind Energy Shine
February 10, 2014 08:20 AM - Sarah Lozanova, Triple Pundit
The North American cold wave has wreaked havoc on energy systems this winter, plagued by natural gas shortages, rising peak power demand and power plants going offline due to extreme weather conditions. The displaced polar vortex, with its frigid temperatures and strong winds, has caused energy use to soar—creating supply shortages and rising energy costs.
With Climate Change, Greenland Is Bracing For Exploitation
February 9, 2014 07:53 PM - Judy Molland, Care2
The ill effects of climate change are becoming well known, and now here's another: The melting ice cap in Greenland has the country now bracing for a gold rush. As the ice melts at record pace in Greenland, the world's miners, oil workers and construction teams are planning to descend on the country in the next few years, to start digging below the retreating icecap for its ores, hydrocarbons and minerals.
The first big bite!
February 7, 2014 11:43 AM - Gareth Trickey, University of Toronto
The first top predators to walk on land were not afraid to bite off more than they could chew, a University of Toronto, Mississauga study has found. Graduate student and lead author Kirstin Brink and U of T Biology Professor Robert Reisz suggest that Dimetrodon, a carnivore that walked on land between 298 million and 272 million years ago, was the first terrestrial vertebrate to develop serrated ziphodont teeth. According to the study published in Nature Communications, ziphodont teeth, with their serrated edges, produced a more-efficient bite and would have allowed Dimetrodon to eat prey much larger than itself. While most meat-eating dinosaurs possessed ziphodont teeth, fossil evidence suggests serrated teeth first evolved in Dimetrodon some 40 million years earlier than theropod dinosaurs.
Global temperatures now available on Google Earth
February 7, 2014 08:04 AM - ClickGreen Staff, ClickGreen
Climate researchers at the University of East Anglia have for the first time made the world's temperature records available on the Google Earth platform. The Climatic Research Unit Temperature Version 4 (CRUTEM4) land-surface air temperature dataset is one of the most widely used records of the climate system. The new Google Earth format allows users to scroll around the world, zoom in on 6,000 weather stations, and view monthly, seasonal and annual temperature data more easily than ever before.
Submarine melting gives rise to sea levels by chewing away the Greenland Ice Sheet
February 6, 2014 11:22 AM - Woods Hole Oceanographic Institution
Over the past two decades, ice loss from the Greenland Ice Sheet increased four-fold contributing to one-quarter of global sea level rise. However, the chain of events and physical processes that contributed to it has remained elusive. One likely trigger for the speed up and retreat of glaciers that contributed to this ice loss is ocean warming.
Study predicts $100 trillion a year in damage due to storm surges
February 6, 2014 08:48 AM - Editor, The Ecologist
New research predicts that coastal regions face massive increases in damages from storm surge flooding over the 21st century - to $100 trillion annually, more than the world's entire economic product today. According to a study published in the Proceedings of the National Academy of Sciences, global average storm surge damages could increase from about $10-$40 billion per year today to up to $100,000 billion per year by the end of century, if no adaptation action is taken.
Peatland plantations drive steep GHG gas emissions in Indonesia's Riau Province

Versatile is the best way to describe the reddish brown fruit born from oil palm trees. Both the flesh and seed of the fruit is used in many applications including cooking, cosmetics, and biofuel.
24 fewer days of winter ice
February 4, 2014 09:09 AM - ClickGreen Staff, ClickGreen
The winter ice season is now 24 days shorter than it was in 1950 as Arctic lakes are freezing up later in the year and thawing earlier, according to a new study. The University of Waterloo research, sponsored by the European Space Agency (ESA), also reveals that climate change has dramatically affected the thickness of lake ice at the coldest point in the season. In 2011, Arctic lake ice was up to 38 centimeters thinner than it was in 1950.
