The FINANCIAL -- The world is getting hotter,
with 2011 one of the warmest years on record, and humans are to blame, a
report by the World Meteorological Organization said on Tuesday,
November 29, from Info CENN.
It warned increasing global average temperatures were expected to amplify floods, droughts and other extreme weather patterns.The WMO, part of the United Nations, said the warmest 13 years of average global temperatures have all occurred in the 15 years since 1997.
That has contributed to extreme weather conditions that increase the intensity of droughts and heavy precipitation across the world, it said.This year, the global climate was influenced heavily by the strong La Nina, a natural phenomenon usually linked to extreme weather in Asia-Pacific, South America and Africa, which developed in the tropical Pacific in the second half of 2010 and continued until May 2011.
One of the strongest such events in 60 years, it was closely associated with the drought in east Africa, islands in the central equatorial Pacific and the United States, as well as severe flooding in other parts of the world.
The WMO report was released to coincide with U.N. climate talks which run until December 9 in Durban aimed at trying to reach agreement on cutting planet-warming greenhouse gas emissions.
Prospects for a meaningful agreement appear bleak with the biggest emitters the United States and China unwilling to take on binding cuts until the other does first. Major players Japan, Canada and Russia are unwilling to extend commitments that expire next year and the European Union is looking at 2015 as a deadline for reaching a new global deal.
The WMO report said the extent of Arctic sea ice in 2011 was the second lowest on record, and its volume was the lowest.
It said the build-up of greenhouse gases put the world at a tipping point of irreversible changes in ecosystems.
Russia experienced the largest variation from average, with its northern parts seeing January to October temperatures about 4 degrees C higher in several places, it said.
U.N. scientists said in a separate report this month an increase in heat waves is almost certain, while heavier rainfall, more floods, stronger cyclones, landslides and more intense droughts are likely across the globe this century as the Earth's climate warms.
The Organization for Economic Cooperation and Development said global average temperatures could rise by 3-6 degrees Celsius by the end of the century if governments failed to contain emissions, bringing unprecedented destruction as glaciers melt, sea levels rise and small island states are submerged.
