“This is the critical decade. If we don't get the curves turned around this decade, we will cross those lines,” said Will Steffen, executive director of the Australian National University's Climate Change Institute.
He and other specialists, speaking at a conference in London, expressed the urgent need to curb carbon dioxide, methane and other climate-altering pollution before the world warms 2 degrees Celsius above the long-term average.
Many climate specialists agree that is the point at which changes in climate and weather will begin to have severe consequences for humanity.
Meanwhile, an international panel of climate scientists published a report that says global warming is leading to more powerful storms, stubborn droughts and heat waves.
The Intergovernmental Panel on Climate Change said countries should prepare for an onslaught of unprecedented natural disasters that will lead to catastrophic financial losses as well as human fatalities.
That put the blame on man-made climate change, population shifts and poverty. The world’s biggest greenhouse gas polluters, such as China and the United States, are still not expected to agree on curbing emissions until 2015, and not put those goals into force until 2020.
