It happens at this time. As you imply, increases, or decreases will be down to local synoptics and temperature differences for a few days yet, as ice is still melting in many areas, whereas in others, the freeze has well and truly begun. Yes I tend to overlook this other site - more in keeping with what the temp charts are giving, though the previous site makes it look more impressive - possibly due to the scale factors. Cheers, James -- James Brown |

Actually the temps above 80 north have been much lower than 2007 and have only risen sharply again the last couple of days. http://ocean.dmi.dk/arctic/meant80n.uk.php Many thanks for that useful link Lawrence - I hadn't seen that before.

Get outta here You were alluding to "Natural cooling cycles Sun and Oceans" and "The same forces that have always varied our climate long before CO2 was seen as an issue" as being indicative of forthcoming increases in Arctic sea ice back to the 1979-2008 mean. I'm simply pointing out that natural forcings (such as solar irradiance and volcanic aerosols) have been negative for the last 50 or 60 years, and at the same time we've had a period of significant global warming. If those natural forcings didn't manage to cause any cooling since mid-20th Century then it's hard to see why they would suddenly start doing so now, unless you have reason to expect (for example) a fairly substantial drop in solar irradiance or increase in large volcanic eruptions. |

If you're so sure then have a stab at forecasting all of those dire consequences predicted by AGW bandwagonist . Go on I'm waiting? So far the apparent experts that tell us they seem to know all there is to know but haven't so far made a great fist of the catastrophic predictions -have they. You are obviously part of the AGW bandwagon that feel very frustrated because their Russell Grant forecasts , have been made to look very Russell Grant. Fancy another stab at this? Its free you know What star sign are you ..Capricorn? |

Bloody hell Michael that was two years ago have you just awoken from a coma and trying to catch up? Anyway I don't even remember writing that, it was over two years ago, I've paid my time and I'm now a changed man- Well the last time I looked. |
