As Arctic climatologist David Barber and his colleagues explain in a recent paper in Geophysical Review Letters, the analysis of what the satellites were seeing was wrong. Some of what satellites identified as thick, melt-resistant multiyear ice turned out to be, in Barber’s words, “full of holes, like Swiss cheese. We haven’t seen this sort of thing before.”
What Barber’s expedition further discovered was that some Arctic sea ice is not only whisper thin, but that even in places with thick ice, the ice was not as solid as satellites had indicated. That thick ice was still there, but largely as individual chunks covered with a veneer of new ice that masked their true nature.

The Earth has been in a period of rapid global warming for the past three decades. The assertion that the planet has entered a period of cooling in the past decade is without foundation. On the contrary, we find no significant deviation from the warming trend of the past three decades. Weather fluctuations exceed the magnitude of average global warming over the past half century. However, the perceptive person should be able to notice that climate is warming on decadal time scales. The global temperature trend over the past few decades has been strong enough that there is a noticeable “loading” of the climate dice that define the probability of unusually warm or cool seasons.

The past year, 2009, tied as the second warmest year in the 130 years of global instrumental temperature records, in the surface temperature analysis of the NASA Goddard Institute for Space Studies (GISS). The Southern Hemisphere set a record as the warmest year for that half of the world.

It’s easy for people in Russia, England and on the eastern coast of the US, with the severe winter conditions they’re experiencing, to forget that on other parts of our Planet are feeling the heat of dangerous climate change. What we should remember is that what we’re witnessing is not so much “Global Warming,” or even “Climate Change,” but “Global Climatic Disruption,” the term coined by President Obama’s chief science advisor John Holdren.

Another disturbing milestone was passed on November 6. The graph below shows that although extent of the Arctic sea ice this past summer was greater than that of 2007, it is now less, a record low for its date. Ice covered the Arctic Ocean in a smaller area on November 6, 2009 than in any other year on November 6 since observations began in 1979.

Photographer James Balog shares new image sequences from the Extreme Ice Survey, a network of time-lapse cameras recording glaciers receding at an alarming rate, some of the most vivid evidence yet of climate change.

Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years, new research indicates. The study, which incorporates geologic records and computer simulations, provides new evidence that the Arctic would be cooling if not for greenhouse gas emissions that are overpowering natural climate patterns.

July was the hottest the world’s oceans have been in almost 130 years of record-keeping.
Breaking heat records in water is more ominous as a sign of global warming than breaking temperature marks on land, because water takes longer to heat up and does not cool off as easily as land.

The planet’s ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998 according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880.

The volume of older crucial sea ice in the Arctic has shrunk by 57 percent from late 2004 to 2008. That is losing more volume of ice than water in Lake Michigan. Thin seasonal ice has replaced thick older ice as the dominant type for the first time on record.
