United Nations Chief Urges Faster Response to Global Warming


Secretary-General Ban Ki-moon on Tuesday urged governments to speed up talks to forge a joint response to global warming, describing it as an "existential challenge for the whole human race."

Ban addressed the opening of the high-level segment of annual U.N. climate talks, involving environment ministers and climate officials from nearly 200 countries. They're discussing future emissions reductions and climate aid to poor countries.

Climate scientists say it's difficult to link a single weather event to global warming, but some say the damage caused by Sandy was made worse by the rise of sea level. Ban said countries are "in a race against time" to reach their goal of keeping the temperature rise below a threshold of 2 degrees C, compared to preindustrial times, when fossil fuels were not being used on today's massive scale, fueling engines of all sizes.
