The United Nations agency that charts worldwide weather has charged that "human-caused climate change" helped make the last decade the hottest on record, due to "humanity's emissions" of carbons and other chemicals into the atmosphere.

The World Meteorological Organization, the U.N.'s Swiss-based weather outfit, said in a new report of climate extremes from 2001-2010 that nature played a role, but that man and worldwide development are responsible for the trend up in temperatures.

The report, "The Global Climate 2001-2010" said humans have been on a one-way trip to ruining the environment, unlike nature's erratic impact. "Unlike these natural back-and-forth oscillations (in natural temperature changes), human-caused climate change is trending in just one direction. This is because atmospheric concentrations of carbon dioxide, methane, nitrous oxide and other greenhouse gases are increasing steadily due to human activities."

The new report said that world's temperature has increased faster since 1971 and that the last decade was the hottest on record. The decade also saw "unprecedented" climate extremes and high-impact weather events around the world.

The report was issued this month in Geneva.

Since releasing the report, the U.N. agency has called on all nations to begin the costly job of building climate change prediction and research centers in order to help develop ways for people to combat global warming.

A week ago, the WMO blamed climate change on the wildfires in California and New Mexico in demanding worldwide action--and spending--to fight global warming.

"The urgency in achieving early successes in this endeavour cannot be overstated," said WMO President David Grimes. "We have seen many recent examples of climate-related extreme events with enormous negative social and economic impacts and the tragic loss of life."

"In the past month, thousands of people fled their homes across central Europe as deadly flood waters rose to levels unseen in some locations in the past 500 years. Drought-fuelled wildfires raged in New Mexico and California, in the USA, and Pakistan suffered its most severe heat wave in decades, with temperatures reaching as high as 51 degrees Celsius," Mr Grimes said.

"Climate services are increasingly necessary because of the rapidly growing climatic impacts," said Norwegian Meteorological Institute Director-General Anton Eliassen, added in a statement. "Climate services must be designed for the end user beginning with the customer, be it the malaria doctor, the fisherman or farmer. We need to think across boundaries. Cooperation is key," said Eliassen.
