  • Forecasters `warned of Horn of Africa drought` last year

    Forecasting systems were warning about a serious drought in the Horn of Africa as much as a year ago — but communication problems between scientists and decision-makers meant the alerts went largely unheeded, according to forecasters. Warnings about the drought — which the United Nations says is the worst in 60 years — were issued last August, when the Famine Early Warning ...

  • Satellites can help monitor and manage African droughts

    Kenyan MP and remote sensing expert, Wilbur Ottichilo, argues the time is ripe for using satellites to spot developing African droughts. The six million square kilometres of the Greater Horn of Africa are home to about 200 million people. Ecologically and environmentally, the region is highly precarious — more than 60 per cent of it is arid or semi-arid and most countries experience irregular ...

  • More frequent drought likely in Eastern Africa

    The increased frequency of drought observed in eastern Africa over the last twenthy years is likely to continue as long as global temperatures continue to rise, according to new research published in Climate Dynamics. This poses increased risk to the estimated 17.5 million people in the Greater Horn of Africa who currently face potential food shortages. Scientists from the US Geological Survey ...

  • Better protection for homes and communities from flooding and drought

    Communities, homes and businesses will be better protected from the risk of flooding and water shortages in future under plans published in the Flood and Water Management Bill by Defra today. The Bill addresses many of the recommendations from Sir Michael Pitt’s review of the summer 2007 floods.  It will give the authorities that manage flood risk better powers to do so, putting local ...


  • Tipping points - the universal warning signals for sudden change

    A study of critical thresholds in complex systems ranging from the human body to financial markets has found that regardless of the details, the dynamics of each system near its 'tipping point' share similar symptoms. The research is published today in Nature and was in part funded by a European Young Investigator (EURYI) Award to co-author Jordi Bascompte of the Consejo Superior de ...

  • Water looms as “the next oil,” warns MIT professor

    With US gasoline prices edging toward the recently unimaginable price of US$4 a gallon, consumers are beginning to drive less and energy efficiency is again a hot topic. But the pain caused by high oil prices is nothing like what looms as an even more basic and essential natural commodity — water -- faces dwindling supplies and growing demand. As essential as it is taken for granted, water is The ...

  • World needs early warning of climate-linked disasters

  • Africa Analysis: Disaster warning not just about science

    The East Africa famine calls into question the wisdom of investing in early warning systems without improving take-up, writes Linda Nordling. When the UN declared a state of famine in the Horn of Africa in July, one group of scientists was not surprised. In August 2010, the USAID-funded Famine Early Warning Systems Network (FEWS NET) had ...

  • Unprecedented early warning of El Niño succeeds

    The current El Niño event has been predicted by an international team of scientists more than one year ago – earlier than ever before. This breakthrough in forecasting the most important phenomenon of natural climate variability has been enabled by novel approach of complex networks analysis of atmospheric temperature data from the Pacific. Such forecast can help farmers in Brazil, ...

  • Eminent Scientists Warn of Disastrous, Permanent Global Warming

    SAN FRANCISCO, California (ENS) - The leaders of the world's largest general scientific society issued an imperative climate change warning Sunday. 'The atmospheric concentration of carbon dioxide, a critical greenhouse gas, is higher than it has been for at least 650,000 years. The average temperature of the Earth is heading for levels not experienced for millions of years.' ...

  • Understanding events of the 1930s, 1950s may help in forecasting future drought

    During the iconic Dust Bowl, great clouds of dust swirled east out of the U.S. Northern Plains, blackening skies as far away as New York. Drought conditions set up in 1932 and didn’t ease for seven years. Just a decade later, another severe drought hit, this one scorching the Southern Plains and Southwest. ESRL scientists seeking to improve today’s drought warning systems recently turned their ...

  • Is Georgia the New California? WaterSignal Offers Solution to State’s Worsening Drought

    The State of California, already under a state-mandated water conservation program, continues to struggle due to property owners – residential and commercial – not heeding the State’s warning.

  • NASA data show some African drought linked to warmer Indian Ocean

    A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region's food security. Rainfall in eastern Africa during the rainy season, which runs from March through May, has declined about 15 percent since the 1980s, according to ...
