world to face drought by year 2100|
Ed Crooks, The Financial Times.
incidence of moderate drought will double to affect half the world by the end
of the century unless greenhouse gas emissions are curbed, according to a study.
modelling of the effect of global warming on water levels
conducted by the Met Office, Britain's official weather
forecaster, also suggests severe droughts could rise sharply,
in the absence of action to limit emissions from the consumption
of fossil fuels.
water shortages threaten to lead to intensifying problems of starvation and international
Met Office forecasts, to be published shortly in a US journal, are based on a
projection of reasonably strong global economic growth, with no mitigation of
greenhouse gas emissions.
In that scenario, global temperatures rise by 1.3
to 4.5 degrees celsius by the century's end.
would mean moderate drought-defined as water levels experienced
during the driest fifth of months in a region in the past
50 years - occurring
