Global warming 'dips this year'
People have made several harm to the asmosphere and thus induce the Global Warming. Now, everyone should have to think about this issue and make better world for next generations.
This would mean global temperatures have not risen since 1998, prompting some to question climate change theory.
But experts say we are still clearly in a long-term warming trend - and they forecast a new record high temperature within five years.
The WMO points out that the decade from 1998 to 2007 was the warmest on record. Since the beginning of the 20th Century, the global average surface temperature has risen by 0.74C.
