Europe faces drought and flood burden

Expatica: A leading climate scientist warned Tuesday that Europe should take action over increasing drought and floods, stressing that some climate change trends were clear despite variations in predictions. "There are some robust areas like Siberia, we know what the climate will be, another robust area is the Mediterranean, because the models tell the same story," said Zbigniew Kundzewicz, review editor of the Intergovernmental Panel on Climate Change's (IPCC) chapter on freshwater resources.

"Climate change will pose two major water challenges in Europe: increasing water stress in southern Europe and increasing floods elsewhere," he added during a workshop organised by the UN Economic Commission on Europe. "Current water management practices may be inadequate to reduce adverse impacts of climate change."

The Polish scientist said southern Europe would be more affected than northern Europe, with evidence already of hotter weather and longer drought leading to water shortages, harm to agriculture, a 20 to 50 percent decrease in hydro-electric power and denser water pollution. Nonetheless, the intensity of rainfall when it does occur is also growing with warming, raising the threat of sudden summer floods such as those that hit eastern Europe in August 2002.

Kundzewicz also highlighted the amplifying impact of shifting land use, including more urban areas which absorb water less readily than rural areas during sudden rainfall. "One hundred years floods may become a 50-year or 20-year flood," he explained….

The Danube River was one of many rivers that overflowed in early April 2006 after being inundated with heavy rain and melting snow. Floods on rivers throughout Central Europe have forced hundreds of people from their homes, reported the Associated Press. Large tracts of land along the Danube in Hungary and Croatia were flooded when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured the top image on April 3, 2006. In the images, water is dark blue or black, clouds are pale blue and white, vegetation is green, and bare earth is tan and pink. Daily images of Central Europe are available from the MODIS Rapid Response Team. NASA images courtesy the MODIS Rapid Response Team at NASA GSFC.
