The best link ever The jury may still be out on that one. It is not well known whether those temperatures were global, or were rather more medieval U.K. weather.http://www.co2science.org/articles/V13/N16/C2.php Just look at the names on that... Phil Jones, Keith Briffa et al In the words of the seven scientists, "temperatures during the warmest intervals of the Medieval Warm Period," which they defined as occurring "some 900 to 1300 years ago, "were as warm as or slightly warmer than present day Greenland temperatures." So 1300 years ago it was as warm or slightly warmer than today and that's before the industrial revolution. It's good to know the MWP is now back in the data Dave

retsof it was a study of Greenland Ice Cores..... Now why would you then not check on some coring work of the Antarctic Vostok maybe, Law Dome spring to mind. Latter is known for superior resolution, showing trace of LIA but not of the fka MWP. CO2Science site... yes you have a knack of finding those xxxx-science sites.

28th April 2003 15th April 2004 25th April 2005 19th April 2006 15th April 2007 25th April 2008 5th May 2009 3rd May 2010 The dates the Sea Ice Extent according to http://www.ijis.iarc.uaf.edu/en/home/seaice_extent.htm fell below 13 Million km2 ![]() Not sure what the significance of this is supposed to be. The weathermen have told us, to those that listen, that freeze up was late, that there was this exceptional 50+ years record strong negative Arctic oscillation winds [one reason why it snowed in England and much of the normal winter outflow of sea ice did not happen into the Atlantic], that the temperatures for a large period were 10C less cold than normal in the Arctic, so whilst as we explained many many times on sea ice extent not being real ice, just the outline, within which there are regions of water, and that any quadrant that holds more than 15% ice is counted as covered, to quote your JAXA source: The sea-ice extent is calculated as the areal sum of sea ice covering the ocean where sea-ice concentration (SIC) exceeds 15%. SIC data of JAXA'Âs AMSR-E standard products are used for this purpose (http://sharaku.eorc.jaxa.jp/AMSR/products/pdf/alg_des.pdf). ... we also eluded many times on multi year ice decline [sea NSIDC/NOAA March chart up in this thread], thickness decline in general, or a few posts up, those doing the 2010 North Pole trek having to take the helicopter to get to 90 degrees north due open water and thin ice, this little cherry pick might mean nothing to you DA, but it does mean something to others, when then the melt season has set in: April 18-May 3 Sea Ice Decline in km square + percent of Arctic SIE peak. 2010 -828,125 lost -5,75% 2009 -529,531 lost -3,67% 2008 -503,125 lost -3,47% 2007 -406,094 lost -2,92% 2006 -812,656 lost -5,90% 2005 -548.906 lost -3,89% 2004 -496.406 lost -3,47% 2003 -743.437 lost -5,01% Looks like 2010 is a record speed decline in absolute km square and 2nd in % decline from peak, just when that copper plow came above the horizon. It's cup cake thin ice. The oceans world wide show record monthly surface temperature anomalies... more vapor to go around with that, more clouds for feedback... you know your ~95% of the GHG's, DA! I'm sure there is something ROFLMAO qualification coming like "There's more ice to melt", yes we saw that one offering in the missing thread, the question to oneself conveniently omitted: WHY? ** Can highly recommend to watch the Richard Alley presentation with your daughters on CO2 being the biggest control knob of our climate... 50 minutes of you lifetime. Like the laws of electrons flowing in your telephone cables, CO2 starts vibrating at 15 um in gaseous form and has all these harmonic sidebands [something also used in telecoms] handing the excess heat of to those water molecules. It only needs the sun to shine down on us to get them going, all 390 ppmv in the Atmosphere we breath. ** Of course Of course, what was I thinking, it must be renewed grinding that makes it disappear like snow for the sun... you know that snow per Rutgers, where the red areas indicate where it's anomalously missing: Daily Departure - May 3, 2010 (Day 123) ![]() PS: It must have started melting in anticipation of the Islandic volcano ash. On the other hand, SOI update of May 4 says La Nina is on a rebound, so that global cooling can resume in earnest. Salute Tutti ![]()

retsof it was a study of Greenland Ice Cores..... Sites on Greenland are more susceptible to snow melt than those in Antarctica. or...when Greenland was more green.

Mark Twain I think said: Climate is what we expect, Weather is what we get.

I love this thread and the friendly arguing.
----------------------------------------Do any of you actually know what you are talking about (like your profession is studying the climate) or are you just very good at finding links supporting your point of view? /Helle (newbie and don't know who you are and what you do for a living) ![]() |

I love this thread and the friendly arguing. Do any of you actually know what you are talking about (like your profession is studying the climate) or are you just very good at finding links supporting your point of view? /Helle (newbie and don't know who you are and what you do for a living) While I personally have no background in climate science, 97.4% of climate scientists say this is real, true, and happening before our very eyes. (or as Dave Autumns et al claim: part of the grand Illuminati-Freemason-Bilderberg-Davos conspiracy) ![]() http://www.skepticalscience.com/global-warming-scientific-consensus.htm Figure 1: Response to the survey question "Do you think human activity is a significant contributing factor in changing mean global temperatures?" (Doran 2009) General public data come from a 2008 Gallup poll. Most striking is the divide between expert climate scientists (97.4%) and the general public (58%). The paper concludes "It seems that the debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes. The challenge, rather, appears to be how to effectively communicate this fact to policy makers and to a public that continues to mistakenly perceive debate among scientists." |

DA, I think you could put the JAXA chart back up just so that the picture can talk to the numbers. The red line is telling a story... the weather forecast has predictive powers to go with that as well.
----------------------------------------Here a more broader impression of how the world turns with 6.8 billion homo sapiens sapiens on it, where electrons in telephone cables are as constant in their function as Infrared has effect on atmospheric CO2 at the 15 um band [other sidebands too]. Arctic Sea Ice Extent and Area for April, where Area dropped! Explanation please? Antarctic Sea Ice Extent and Area, same as the NSIDC chart, but with addition of the real sea ice. It's down. Explanation please? ![]() Global... well it's obvious, the real ice is on a steeper slope down than extent...which tells me and many others more about the state of the polar regions... like the title of that Stephen King book - Thinner. ![]() PS: Wonder if the canoe guy is going to try again this year... peddle there... one needs to take a helicopter to get to 90 degrees north of the equator, in April 2010. Breaking up is hard to do, but not at the poles these days.
