Eftirfarandi skringar standa fyrir nean myndina sem fengin var a lni fr Climate4you vefsunni sem haldi er ti af prfessor Ole Humlum (greinar) hj Oslarhskla:

Superimposed plot of all five global monthly temperature estimates shown above. As the base period differs for the different temperature estimates, they have all been normalised by comparing to the average value of their initial 120 months (10 years) from January 1979 to December 1988. The heavy black line represents the simple running 37 month (c. 3 year) mean of the average of all five temperature records. The numbers shown in the lower right corner represent the temperature anomaly relative to the above average. See also the diagram below. Values are rounded off to the nearest two decimals, even though some of the original data series come with more than two decimals. The above air temperature estimates may be compared with variations in the global oceanographic heat content above 700 m depth. Last month shown: November 2010. Last diagram update: 22 December 2010.

It should be kept in mind that satellite- and surface-based temperature estimates are derived from different types of measurements, and that comparing them directly as done in the diagram above therefore in principle is problematical. For that reason, in the analysis below these two different types of global temperature estimates are compared to each other. However, as both types of estimate often are discussed together, the above diagram may nevertheless be of interest. In fact, the different types of temperature estimates appear to agree quite well as to the overall temperature variations on a 2-3 year scale, although on a short term scale there may be considerable differences.

All five global temperature estimates presently show stagnation, at least since 2002. There has been no increase in global air temperature since 1998, which was affected by the oceanographic El Nio event. This does not exclude the possibility that global temperatures will begin to increase again later. On the other hand, it also remain a possibility that Earth just now is passing a temperature peak, and that global temperatures will begin to decrease within the coming 5-10 years. Only time will show which of these possibilities is the correct. Click here to read a few additional reflections on the recent period of global temperature stagnation.

Snow and ice bring travel chaos to UK

Flights cancelled and drivers hit by holdups as heavy snowfall and falling temperatures disrupt Christmas getaway

Friday 17 December 2010 18.01 GMT

Heavy snow and freezing conditions returned to Britain today with travel chaos expected over the weekend as forecasters predict more snow.

Britain's second largest airport, Gatwick, warned it might be forced to close and easyJet said tonight it was suspending flights there between 6am and 10am, coinciding with an expected snowstorm.

Some parts of England are expected to be hit with between 25cm and 30cm of fresh snow, just as many up and down the country begin the big Christmas getaway...

White hell: Drivers spend night sleeping in their cars as coldest December on record shuts roads and airports

  • Heathrow Airport closed for most of today
  • Hundreds of drivers trapped on M6 overnight
  • Ambulance skids off road and kills passenger inside
  • Backlog of up to 4m parcels could remain undelivered
  • Urgent appeal for blood donors after concerns of shortages
  • Grit to be shared amid fears of cold snap until January 14
  • Odds shortened even further on White Christmas

Millions of Britons were facing travel chaos today as snow and ice left motorways and airports closed and train services disrupted.

Heathrow Airport has cancelled all flights between 10am and 5pm today, with further problems at Gatwick and in Ireland, Scotland and Wales.

Overnight blizzards and plummeting temperatures buckled a huge chunk of the country's road, air and rail networks on the busiest weekend for travel and shopping before Christmas.

As the mercury plunged, hundreds of drivers were forced to spend the night in their cars on the M6 after a lorry jackknifed at midnight.

The North West was hit with deluges of up to 10in of snow while parts of the south were also blanketed overnight, with blizzards expected in parts of the South East and Midlands today....

Dickens Christmas carol

Af vefsu Earth Observatory:

Snow lingered in Great Britain and Ireland on December 8, 2010. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Aqua satellite captured this natural-color image the same day.

Snow extends from Northern Ireland southward past Dublin, and from Scotland southward into England. Snow cover stops short of London; the white expanses in that area are clouds. Snow and clouds present an almost uniform white to the satellite sensor, but clouds can be distinguished from the underlying snow by their billowy shapes and indistinct margins. Rugged hills and gray-toned urban areas interrupt the snow cover, especially in northern England.
