A hot year is normally associated with a vintage year
for wine growers but global warming could, by the end
of the century, have adverse effects on vineyards in
Southern France and California.
at a conference on the impact of global warming on the
wine industry Gregory Jones, associate professor of
geography at the American University of Southern Oregon
said "in the future, warming could become disastrous
in numerous regions."
first studies on the consequences of global warming
show that warming favours the quality of the wine but
the threat might come from a series of challenges,"
he said, citing problems with irrigation, diseases,
and soil erosion resulting from flooding.
Sequin, from the French National Institute for Agricultural
Research, said, "heat, it''s sometimes a good thing,
up to a certain threshold," citing the heat wave
that hit Europe in 2003 gave some idea of what is in
store in the future.
was generally positive for the harvests in the North
France but less so in the South," Sequin said.
regions most threatened by global warming are those
with the hottest climates, such as Southern Europe and
California in the US.
nothing is done about global warming, only the coastal
California, cooled by the ocean breeze, will be good
for cultivating vines by 2100, Jones said.
