   It appears that the now official records show that this (worldwide land & ocean average) winter of 2007 - 2008, to be the 16th warmest on record, and the coolest since 2000 - 2001.  For the U.S., it was the 54th warmest.


   Here is the link to NOAA.  It has the worlds largest database of weather and climate information.  It is scientific sites such as this, which should be used for referencing information pertaining to climate change, global warming, global cooling, etc., not political or politically aligned organizations.

   This past winter, even though it was the coldest since 2000 - 2001, still neatly fits into the scenario of global warming.  Some regions experienced warmer than average temps, some experienced temps a little colder, while still others received much colder  temps.  It must be understood that the average temps variations from some of the warmest to some of the coldest winters of the past century, differ by only a few tenths of one degree (in this case) fahrenheit, above or below the mean temperature of the last 100 years.


   Here's a excerpt from a short article by Brett Anderson, the Senior Meterologist at Accuwaeather.com, explaining the Arctic Ice "comeback".

Arctic Still on Thin Ice





The colder-than-average winter over some parts of the arctic has yielded an increase in new sea ice area, but wait a minute, the older (perennial) sea ice that lasts for several years has continued to decrease, according to NASA researchers.


NASA microwave data indicates that perennial sea ice currently covers less than 30% of the Arctic, compared to 50-60% in the recent past.


Very old sea ice that remains in the Arctic for at least 6 years covered 20% of the Arctic area back in the mid to late 1980's, but this winter that figure is down to just 6%.


The maps below shows the decrease in older sea ice by comparing the average February conditions from 1985-2000 with February of 2008. The image is courtesy of the National Snow and Ice Data Center.


Walt Meier of the National Snow and Ice Data Center, says that this winter the ice cover is much thinner overall and thus in a more vulnerable state heading into the summer melt season.


This month, satellite data showed the maximum sea ice extent slightly increased by 3.9 percent over that of the previous three years, but it is still below the long-term average by 2.2 percent. Increases in ice extent occurred in areas where surface temperatures were colder than the historical averages. At the same time, as a result of the export of ice from the Arctic, the area of perennial ice decreased to an all-time minimum, according to the NASA article.

   I've just seen an interesting statistic on the Weather Channel.  They are statistics on daily record high and low USA temperatures set, since January 1st, 2000, through July 2008.  I'm presuming they are from official/registered reporting stations, which have been continously active and reporting since Jan. 2000.  They also did not state as to whether the records information was from their database, or whether it was referrenced from another source, such as NOAA. 


   The record daily highs set during this period (rounding off to the nearest hundred) are 151,200.  The record daily lows set during the same period, are 69,300.  Though they didn't specify, I think they are referring to all 50 states.  I wonder though, if Puerto Rico and the U.S. Territories, are included in these stats.  I wonder if other areas of the world have a comparable, in the vicinity of, a two to one ratio.
