UN warns world's water cycle becoming more unpredictable

Increasingly intense floods and droughts are a "distress signal" of what is to come as climate change makes the planet's water cycle ever more unpredictable, the United Nations said Monday.

Last year the world's rivers were their driest for more than 30 years, glaciers suffered their largest loss of mass in half a century and there were also a "significant" number of floods, the UN's World Meteorological Organization said in a report.
