Scientists trying to pinpoint Global Warming forecasts

Moving on from the risk of global warming, scientists are now looking for ways to pinpoint the areas set to be affected by climate change, to help countries plan everything from new crops to hydropower dams.

Billion-dollar investments, ranging from irrigation and flood defences to the site of wind farms or ski resorts, could hinge on assessments about how much drier, wetter, windier or warmer a particular area will become.

But scientists warn precision may never be possible. Climate is so chaotic and the variables so difficult to compute that even the best model will be far from perfect in estimating what the future holds.
