The results are reported in the June 19 edition of the journal Nature. An international team of researchers, including Lawrence Livermore National Laboratory climate scientist Peter Gleckler, ...

  • Fewer rain storms across southern Australia

    In an address today to the International Union of Geodesy and Geophysics conference in Melbourne, CSIRO climate scientist, Dr Jorgen Frederiksen, said these changes are due to reductions in the strength of the mid-latitude jet stream and changes in atmospheric temperatures. The jet stream comprises fast moving westerly winds in the upper atmosphere. "The drop in winter and autumn rainfall ...

  • Europe’s hot summers break 2,000-year record

    The unusually hot summers in Europe over the last three decades are further evidence that human activities are largely responsible for recent global warming, according to new research. This new data adds to the fears expressed by scientists only a week ago that parts of the Mediterranean and Arctic regions will heat up by 3.4˚C and 6˚C respectively above pre-industrial levels. The new ...

  • Torrential rainfall a common climate feature in the future

    Changes in the climate are expected to result in heavier rainfall. Calculations with climate models show that a heavy downpour will give 20-30 per cent more rain at the turn of the next century. Thunder showers and torrential rainfall in the summer are part of what, in technical jargon, is called extreme or intensive short-term precipitation. “Intensive short-term ...

  • More than 100 climate simulations show the future climate
