  1. I am a long time lurker and remember your regular postings back in 2012 and earlier. I have missed them as they were always technically very good and not biased in any way.Hope you find the time and instigation to post more often again.

      :good:Indeed! Waterspout was a frequent contributor to the TWO climate forum in the good old days - he provided a lot of interesting information.

  2. I really enjoy reading your posts Frosty, and rarely post in here, but let's not get too carried away with hyperbole regarding Autumn Hot spells. A brilliant article by Mr Eden Sums it up, and we are not even Late September yet...... http://www.bbc.co.uk/news/magazine-15127159
  3. The Wind dataset in a GRIB file should be stored as 'U' and 'V' components. Extracting the Speed is then SQR(U^2 + V^2) Extracting the Direction a bit more complex: (180 / PI) * ATN( U / V) But then adjust the angle relative to North as follows: If V > 0 Add 180 if U>0 and V<0 Add 360
  4. I think I knew what you meant, Peter, but some might have assumed you meant the chemistry of the entire atmosphere! Yes, the Carbon molecules have increased. They have a specific absorption spectrum, and saturation points. I think alot is known how Carbon acts in the laboratory, but not neccessarily in the entire 'atmosphere' where it competes with Water Vapour in alot of that absorption Spectrum. I think this is why we are not seeing the proposed temperature response the models predicted back in the 90's - the sensitivity is almost certainly much less than what scientists might have us beli
  5. Could you show this 'entire' change using this pie chart please, Peter!
  6. They've now changed it: "This is very well spotted and is an error on our part. The press release has now been amended to ‘very unusual’ rather than ‘unprecedented’. Many thanks for bringing my attention to this. Kind regards,"
  7. Oh yes! I must email the BAS, as their press release is rather misleading and not the same as to what the Paper abstract clearly says.
  8. There's some new research just published in Nature "Antarctic Peninsula warming relative to Holocene climate and ice shelf history" - which reconstructs temperatures for the past 15,000 years. I havn't been able to see the paper, or indeed a graph, but I'm a little confused. The BAS report on it as follows: http://www.antarctica.ac.uk/press/press_releases/press_release.php?id=1892 Their summary being: "The first comprehensive reconstruction of a 15,000 year climate history from an ice core collected from James Ross Island in the Antarctic Peninsula region is reported this week in the journal N
  9. I think the study assumes temperatures responded to co2 releases, whereas the co2 release may have been prompted by the temperature rising first due to some other natural cause. Also, the PETM was started by a massive Methane release. It's like comparing Apples with Oranges if this is the nearest comparison to today! Also, we don't currently have any "Severe Global Warming" - the temperature peaked Circa 1998. The new CERN data, regarding Cosmic Rays, will be interesting, as the Authors say they cannot state the exact results, as this is not allowed before publication. So, be interesting to
