13 of last 15 years warmest on record
From: AFP November 29, 2011 8:36PM

THIRTEEN of the warmest years recorded have occurred within the last decade and a half, the UN’s World Meteorological Organisation said today.

The year 2011 caps a decade that ties the record as the hottest ever measured, the WMO said in its annual report on climate trends and extreme weather events, unveiled at UN climate talks in Durban, South Africa.

“Our science is solid and it proves unequivocally that the world is warming and that this warming is due to human activities,” WMO Secretary-General Michel Jarraud said in a statement, adding that policymakers should take note of the findings.

“Concentrations of greenhouse gases in the atmosphere have reached new highs and are very rapidly approaching levels consistent with a 2 to 2.4 Celsius rise in average global temperatures.”

Scientists believe that any rise above the 2.0 threshold could trigger far-reaching and irreversible changes on Earth over land and in the seas.

The 2002-2011 period equals 2001-2010 as the warmest decade since 1850, the report said.

2011 ranks as the 10th warmest year since 1850, when accurate measurements began.

This was true despite a La Nina event – one of the strongest in 60 years – that developed in the tropical Pacific in the second half of 2010 and continued until May 2011.

The report noted that the cyclical climate phenomenon, which strikes every three to seven years, helped drive extreme weather events including drought in east Africa, islands in the central equatorial Pacific and the southern United States.

It also aggravated flooding in southern Africa, eastern Australia and southern Asia.

While La Nina, and its meteorological cousin El Nino, are not caused by climate change, rising ocean temperatures caused by global warming may affect their intensity and frequency, scientists say.

Here’s the original report. Worth reading.

    “THIRTEEN of the warmest years recorded have occurred within the last decade and a half, the UN’s World Meteorological Organisation said today.”

    Since 1888. Interesting extrapolation.

    Comment (hc): What evidence do you want? The claimed warming has occurred over about the last century. Climate sceptics have spread the lie that warming has stopped over the last decade. Is the clear refutation of this position what upsets you?

    Professor,

    Stick to the point. The warmest 13 years on record since 1888? This is a laughable extrapolation. It would be far better to argue that science supports the hypothesis that more C02 causes warming, which it does through experiments.

    A record since 1888 is not evidence. It’s only evidence fruit religious fruitcakes.

    on a related issue I see Rafe has well and truly jumped the shark on AGW.

    so have the rest of commenters. They clearly have no idea of statistics.
    the main question is whether Sinclair is merely exacerbating this by presenting obviously misleading material or he has jumped as well.

    He is playing both ends for the middle, self advancement being the main game.
