UN sends global warming alert | World | BigPond News
Climate change experts say a new UN report shows deadly extreme weather events will increase unless nations tackle global warming.
An Intergovernmental Panel on Climate Change (IPCC) report released overnight states that global warming is leading to such severe storms, droughts and heatwaves that nations should prepare for an unprecedented onslaught of dangerous and costly weather disasters.
In the past, the IPCC, founded in 1988 by the UN, has focused on the slow inexorable rise of temperatures and oceans as part of global warming.
The latest report is the first to look at the less common but far more noticeable extreme weather changes which recently have cost on average about $77 billion a year in damage.
