    IPCC report from 2013 (AR5, Working Group 1) where in chapter 5.3.5. the IPCC scientists admit (pdf here):
    The reconstructed temperature differences between MCA and LIA […] indicate higher medieval temperatures over the NH continents […]. . The reconstructed MCA warming is higher than in the simulations, even for stronger TSI changes and individual simulations […] The enhanced gradients are not reproduced by model simulations … and are not robust when considering the reconstruction uncertainties and the limited proxy records in these tropical ocean regions […]. This precludes an assessment of the role of external forcing and/or internal variability in these reconstructed patterns.


    I guess the media and Michael Mann never got this bit as it was not in the summary. The data was warmer than the models could make it and still models were chosen over observation.

    So you've dismissed a 464 page report based on one out of context sentence?

    Hurray we are back to questions about charts and stuff. Sisu can you please explain the cycle you claim we are in as demonsrated by that beloved backcast chart ( I can post it for you again if you need it).

    A waste of time mate, he's ignored umpteen questions in the last week or 2.

    He came back with a cover all of "I'm not reading your posts, merely posting" (which was a lie) the other day, trying to intimate that he was a puppet master....and then in the next sentence challenged Donga on his last post

    Yeah I seen that rather pathetic attempt, its eerily similar to when he has claimed to have you, myself and others on ignore in the past and suddenly starts replying.
    It is a bit sad really and I do feel sorry for him at times but he won't learn.

    ? What? The medieval period is generally considered to be the fall of the Roman Empire until the Renaissance. Are you saying the whole of the southern hemisphere was under water then? That's around the time the Maoris travelled from Hawaii to NZ, isn't it?

    Confused again. <confused>

    Clues left at a galactic hit-and-run
    Unusual gas ripples offer signs of a dwarf galaxy speeding away

    GALACTOSEISMIC ACTIVITY The Milky Way’s gas (left image) and stars (right) might have been disturbed by a close run-in with a dwarf galaxy (blob at bottom left of both images), as seen in this computer simulation.

    SUKANYA CHAKRABARTI/ROCHESTER INSTITUTE OF TECHNOLOGY

    The study of disturbances in a galaxy’s structure (essentially, galaxy quakes) to discover dark, but massive, cosmic objects.

    KISSIMMEE, Fla. — Ripples in the Milky Way’s outer layers of gas were the first clue. Now, scientists suspect they have found a small, faint galaxy that brushed past our galaxy a few hundred million years ago. This dwarf galaxy doesn’t have many stars, but it is rich in dark matter, the invisible but predominant source of mass in the universe. Sukanya Chakrabarti, an astronomer at the Rochester Institute of Technology in New York, reported the findings January 8 at a meeting of the American Astronomical Society.

    Chakrabarti first came up with the idea of a dwarf galaxy hit-and-run in 2009 as a way to explain the puzzling galactic ripples. In 2015, her team reported finding stars where she had predicted the runaway galaxy to reside, about 300,000 light-years away in the constellation Norma. Now, Chakrabarti says she has determined that three of the stars are speeding awayat about 200 kilometers per second, compelling evidence that the stars are part of a gravitationally bound system bolting from the Milky Way.

    The researchers still need more evidence to prove they have seen a dwarf galaxy. But if the finding is confirmed, it will mark the first use of galactoseismology to discover an object via the galactic crime scene it left behind.

    © Provided by The Independent The cool conditions to come will be a sharp change from the mild weather last month (Picture: [copyright])Temperatures are expected to plummet as low as -15C in parts of the UK over the coming days as several inches of snowfall threatens to block roads and railways.

    Even London could see light snow as the cold snap takes hold, bringing ice, frost and Arctic winds to the country.

    Amber and yellow warnings are in place on Wednesday and Thursday in parts of northern England and Scotland, with the heaviest snow arriving in Shetland and border regions tonight.

    The Met Office is urging people to prepare for “very difficult travelling conditions” and possible disruption to transport and power supplies, while cold alerts have been issued by Public Health England and charities for asthma sufferers and the elderly.

    Global cooling? <yikes>

    saw a progame once tht said that the beautiful spirals of their shells, often quoted by Creationists as being the work of God, is actually based on the mathematical pattern of 1-2-3-5-8-13-21-34-55, etc.

    They do not exist , i can't believe you have fallen for the scam, the snail sellers realised that mouthbreathers will pay a lot more for them if the have a fancy name, the problem is after a while and it grows a little you realise you were suckered into buying a baby snail!

    PS if you want proof I have pictures of them once they grow up.

    Fibonacci Sequence? (Though there should be an extra "1" at the beginning).

    yes, iot's in all natural spirals, from nautilus shells to pine cornes. Is God a mathematician? Did his mum and dad give him a Spirograph set for Christmas? :emoticon-0143-smirk
