Hotter, dryer, but less frost the outlook for Australia?

摘要

THE NUMBER of very hot summer days in some Australian cities could double by 2030, according to the CSIRO. This conclusion is consistent with findings that summer heatwaves will be common in Europe by the end of this century. A report by European rese archers in the journal Nature recently made this announcement which did little to surprise either the CSIRO or the Bureau of Meteorology, says Kevin Hennessy, senior research scientist with the CSIRO's Atmospheric Research Climate Impact Group. "We have analysed climate change projections from nine climate models," says Hennessy, "and by the year 2030 we expect most of Australia to become 0.4 to 2,0 degrees warmer on average, with 10 to 50% more summer days over 35 deg."
