Better Water Use Can Cut Global Food Gap

Climate News Network: Although growing human numbers, climate change and other crises threaten the world‘s ability to feed itself, researchers believe that if we used water more sensibly that would go a long way towards closing the global food gap. Politicians and experts have simply underestimated what better water use can do to save millions of people from starvation, they say. For the first time, scientists have assessed the global potential for growing more food with the same amount of water. They found that...

Amazon Deforestation Threatens South America Water Security

Climate News Network: The continued destruction of the Amazon to exploit its resources for mining, agriculture and hydro-power is threatening the future of the South American continent, according to a report by campaigning groups using the latest scientific data. Five countries--Bolivia, Brazil, Colombia, Ecuador and Peru--share the Amazon, and for all of them the forest area occupies more than 40 percent of their territory. All face threats to their water supply, energy production, food and health. In addition,...

Greenhouse Gas Emissions Rate Puts Billion More at Risk

Climate News Network: Allowing the Earth’s temperature to rise by more than 3.6ºF will see dramatic changes in vegetation across the planet and expose a billion more people to severe water scarcity, according to new research. So vast are the potential changes that the scientists from the Potsdam Institute for Climate Impact Research (PIK) in Germany comment that they doubt if humans have the capacity to manage the impacts it will have. A temperature rise of 9°F would cause all ice-free land on the planet to experience...

Catastrophic Oil Spill Threat to Canadian River Basin

Climate News Network: The Mackenzie River Basin, a vast globally important area in Canada, is at great risk from climate change and a catastrophic oil spill from the tailing ponds of tar sands mining, according to a panel of nine Canadian, American and British scientists. The warning came just days after the Canadian Oil Producers Association says it expects oil production from tar sands in the region to double by 2030. The Mackenzie River Basin showing how it drains north to the Arctic Ocean. A report produced after...

Clouds ‘Cool Earth Less Than Once Thought’

Climate News Network: Extra cloud cover caused by emissions of industrial pollutants is known to reduce the effects of global warming, but its impact in reducing temperatures has been over-estimated in the climate models, new research has found. This is particularly significant for China and India, because it has been believed that these two giant countries would be partly shielded from the effects of climate change by their appalling industrial pollution. The Max Planck Institute for Chemistry in Germany believes...
