  • Could Reducing Global Dimming Mean a Hotter, Dryer World?

    Despite concerns over global warming, scientists have discovered something that may have actually limited the impact of greenhouse gases in the atmosphere in recent years by reducing the amount of sunlight reaching the surface of the Earth. In research they published last year in the journal Geophysical Research Letters, a team led by Beate Liepert…

  • Climate Forecasting Systems Help Predict Malaria Risk in Africa

    A recent study published in Nature shows that climate forecasts can help predict malaria epidemics many months in advance. These predictions can alert health service managers to changes in epidemic risk five months before the peak malaria season and four months earlier than predictions based on actual rainfall. The study appears in the February 2…

  • Researchers Confirm Role of Massive Flood in Climate Change

    Flood of fresh water disrupted ocean circulation and Earth’s climate; simulations validated by climate proxy record

  • Answers About the Earth’s Energy Imbalance by James E. Hansen, Director of the Goddard Institute for Space Studies

    Below are answers to typical questions about this research topic and its implications provided by James E. Hansen, director, NASA’s Goddard Insittute for Space Studies. Hansen was lead author on a paper published by Science in April 2005 on this topic. What is the direct significance of the energy imbalance found by the authors in…
