Is the current warming trend global or regional ?

    Just the bare minimum of research will show that the Northern Hemisphere is currently warming much faster than the Southern hemisphere. That CAGW advocates insist that it is because of the ocean/land mass ratio of the two. However looking back 100 years the 2 were in lockstep until recently. Did the Southern hemisphere suddenly lose land mass and I missed it ? Thoughts anyone?

    GENEVA -- The northern hemisphere has been warming twice as fast as the southern hemisphere in recent years, the U.N's weather agency said Thursday.

    In its annual report on the state of the global climate, the World Meteorological Agency said that in the period 1997-2006 the average temperature in the north was 0.53 degrees Celsius (0.95 Fahrenheit) warmer than the average for 1961-1990.

    In the south, average temperatures rose by 0.27 degrees Celsius (0.49 Fahrenheit) in the same period, according to the report.

    "So far the northern hemisphere is warming much more than the southern hemisphere," WMO expert Omar Baddour told The Associated Press.

    He said one reason for the difference was the greater proportion of land to water surface in the north.

    "The oceans respond much slower to any change in temperature. This explains why the northern hemisphere, which has more land than the southern hemisphere, got as much as twice the increase in temperature than in the southern hemisphere," Baddour said.

    Another factor was a fast-spinning ring of air over the Arctic which affects the jet stream that helps drive the movement of winter storms, he said.

    "Part of the explanation comes from the fact that what is called the North Atlantic Oscillation dominates the northern hemisphere, in particular the Atlantic and Europe area," Baddour said.

    At the moment this weather effect is contributing to warming in the north, he said, but this could change.

    Globally, temperatures have been rising by 0.18 degrees Celsius (0.32 Fahrenheit) each decade for the last thirty years, according to the report.

    The effects have been seen in unusually mild winters and autumns, and extreme temperatures during the summer months, WMO said.

    Large parts of Europe had their warmest autumn in 2006 since records began, while the thermometer peaked at 44.2 degrees Celsius (111.6 Fahrenheit) in Sydney, Australia, and 44.6 degrees Celsius (112.3 Fahrenheit) in Bom Jesus, Brazil, this year.

    Overall, temperatures were 0.42 degrees Celsius (0.76 Fahrenheit) higher in 2006 than during the 1961-1990 period.


    and a pretty picture for those with data aversion

    The arctic and the antarctic have always operated on different trends, but, since someone somewhere took a thermometer and dived to some deep region of the ocean next to a lava vent, and found that the water was warm there, then clearly it is global and not regional.

    Since the difference in warming between the northern and southern hemispheres goes back over 20,000 years, nothing has changed. Scientists have identified several mechanisms explaining this difference, including ocean currents, air pollution, shifting precipitation patterns, and upper atmospheric currents. Real science not only welcomes questions, it actually tries to solve them.

    so how can you post that statement and support the CAGW fools. Seems like most of the CAGW people spend more time demonizing scientists such as Dr Judith Curry and Dr Roy Spencer than they do pursuing science

    http://dailycaller.com/2014/03/17/u...ands-imprisonment-for-climate-change-deniers/

    In contrast the skeptics mantra is " the science isn't settled"

    Now if you truly believe that real science questions you should head over to the GWPF site and delete any bookmarks to Cook's skeptical nonscience

    So that's how you learn about what real scientists do -- by reading The Daily Caller and Reddit? No wonder you're so misinformed.

    Some parts of science are settled and some parts aren't. Since nobody in Denierstan actually reads science, they have no way to tell which is which.

    GWPF founder Nigel Lawson said, when the organization was founded, that they were really, really interested in the politics of global warming, but didn't really care for all that sciencey stuff. And that's you're "scientific" source? No wonder you're so misinformed.

    From your own beloved Daily Caller:

    "We will certainly be actively involved in monitoring what is being said, in correcting errors where the are errors. The only thing we will not be actively engaged in is what are the causes of the temperature changes on the planet: how much is CO2, how much is solar radiation, how much is cosmic rays. We won't be getting into all that."

    -- Nigel Lawson, GWPF founder

    That is humorous coming from someone who relies on a cartoonists blog for most of his data and then links a newspaper article to back his opinion. Have you ever considered educating yourself instead of posting others opinions. It is a bit of work but well worth it, trust me. Do you really think the politicians and their billionaire backers give a (*)(*)(*)(*) about you?

    I'll take a cartoonist's blog over a politician's blog any day, especially when that blog can accurately represent scientific research on the subject.

    Have you ever considered backing up your opinions with actual, sources so people don't think you're just pulling (*)(*)(*)(*) out of your ass? It's a bit of work, but well worth it, trust me.

    Like nature itself, I don't really give a (*)(*)(*)(*) what politicians or anonymous internet users think about me.
