Africa takes fresh look at GMO crops as drought blights continent

Reuters: A scorching drought in Southern Africa that led to widespread crop failure could nudge African nations to finally embrace genetically modified (GM) crops to improve harvests and reduce grain imports. The drought, which extends to South Africa, the continent's biggest maize producer, has been exacerbated by an El Nino weather pattern and follows dry spells last year that affected countries from Zimbabwe to Malawi. Aid agency Oxfam has said 10 million people, mostly in Africa, face hunger because...

Agence France-Presse: Thousands of power plants worldwide face sharp reductions in electricity output by mid-century due to more frequent heatwaves and drought driven by global warming, according to a study published Monday. "We need to be concerned as electricity will become more expensive and less reliable in the future due to climate change," co-author Keywan Riahi of the International Institute for Applied Systems Analysis in Austria told AFP. If warming continues unchecked, higher temperatures and water shortages...

Zimbabwe turns to fossil energy, as drought bites

Herald: With back-to-back droughts since 2013, Zimbabwes main hydroelectric power plant at Kariba is failing, forcing the southern African nation to turn to dirtier fossil fuel-based energies to make up for the deficit. The Kariba Hydropower Station is capacitated to generate 750 megawatts of electricity, but the plant has operated at just 63 percent of capacity since early October when the Kariba dam began to dry up. In good times, hydropower accounts for over 50 percent of...

California drought putting many trees at risk
2016-01-02 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: California's forests are home to the planet's oldest, tallest and most-massive trees. New research from Carnegie's Greg Asner and his team reveals that up to 58 million large trees in California experienced severe canopy water loss between 2011 and today due to the state's historic drought. Their results are published in Proceedings of the National Academy of Sciences. In addition to the persistently low rainfall, high temperatures and outbreaks of the destructive bark beetle increased forest...

New York Times: Under a midmorning sun that augured punishing heat later in the day, a handful of cows stood still inside a small pen, their ribs protruding. Too weak to reach the nearest grassy field some miles away, some munched on tall grass that their owner had cut from a strip of land along the highway, in a desperate attempt to save his cattle from the drought afflicting the land. The owner, T. J. Koee a former miner and a full-time cattle farmer for the past 16 years listed the droughts toll this...
