    Thanks for the link......AGW exposed as a hoax.....Again!!

    Taxpayers are becoming more and more pi$$ed off at the CAGW Hucksters. Attention Warmers.....Better Lawyer-up!!

    And for the 'Dook' character who challenged the existence of a European Geophysical Union journal (I'm one of his 'Blocked Victims') in a 'question' he posted after Maxx's: http://www.egu.eu/publications/open-access-journal...

    There are some other links but I did not wish to spend much time on something so simple.

    German scientists Horst-Joachim Lüdecke, Alexander Hempelmann and Carl Otto Weiss have published two influential studies in the European Geophysical Union journal. The first, published in 2013, examined the past 250 years of climate history. The second, published earlier this year, extended the research through the past 2,500 years.

    Current warming is nothing unusual graph:

    According to the 1990 IPCC report on page 202, ONCE. And that hot period lasted about 1000 years.

    Depends on what constitutes 'time'. If you mean a second, day, week, or month the answer would be very many. Even for years it would be many, especially if now is a different time frame.

    From my research never. You need to go back more than 12,000 years to get to these temperatures and even in those cases it was localized not world wide.

    German Physicists ? Do they have names? do they have PhDs in fields that relate to global warming ? Do they work for Universities or are they sponsored by oil companies? and even do those Universities accept cash from Oil, Plastic or Automotive industry ? It was proven long ago you can get anyone to state the opinion you want if it is financially in their interest to do so. That's not considered bribery it's just protecting your financial butt and most but not everybody will do it.

    1250 years ago in the medieval warm period the temperature was substantially greater than it is today.

    Previous to this temperature was higher than today's value at a peak 6,000 years ago in the period known as the Holocene maximum. This was around the bronze age and lasted for several millennium.

    Never, not according to the most recent and comprehensive temperature reconstructions.

    Some studies have concluded that it has not been this warm in at least 5,000 years, at the peak of natural warming due to the earth's orbit. I've seen other studies conclude that it has never been this warm on earth in human existence.
