Dissapearing Ice At The Top of The World and The Roof of the World

The news that the Arctic sea ice approached very near the 2007 record is about a month old now, but the NSIDC has a rather amazing graph showing the trend since 1978. This is just one aspect of the ice and perhaps not the most important. The old ice in the Arctic has nearly disappeared in many areas now. Take a look at this video from NOAA and made by …

NASA Video of the Summer 2011 Arctic Melt

In case you have not seen this video- As I mentioned yesterday, the NSIDC put this summer’s minimum of ice as the 2nd lowest on record. When talking about the sea ice, there are three measurements that are most important. 1.Extent and 2. Area are calculated differently and the IARC website describes it very succinctly here: “The area of sea-ice cover is often defined in two ways, i.e., sea-ice “extent” …

NASA: Global Temps. In August 2011 4th Warmest. Sea Ice Melt Comes in Number Two

NASA-GISS has put up the numbers for August, and the global  land and ocean temperatures in August were the 4th warmest on record. NOAA has August pegged at the 8th warmest using a slightly different methodology. Land temperatures in August were the second warmest on record according to the NOAA-NCDC data. The summer Arctic sea ice melt has ended, and NSIDC says the minimum sea ice was the second lowest …

Arctic Ice At Record Low- Univ. of Bremen

The Volume of the ice also appears to be at a record low, but NSIDC is still showing the extent to be a little above 2007. Ice area is different from the extent and it too seems to be at record low values. All in all, 2011 is either the new winner or has reached the levels of 2007, depending on how you look at it.

2011 Arctic Ice Reaches Second Lowest on Record- One or two weeks of melting left.

The NSIDC updated the Arctic ice numbers today and announced that the ice melt has now reached the second lowest on the satellite record. From NSIDC: Overview of conditions Average ice extent for August 2011 was 5.52 million square kilometers (2.13 million square miles). This is 160,000 square kilometers (61,800 square miles) above the previous record low for the month, set in August 2007, and 2.15 million square kilometers (830,000 …

New Record Low For Arctic Ice Very Possible

  For a while, it looked unlikely the summer melt would bring a new record low in Arctic sea ice this year, although it looked likely to reach the top 3 or 4. No more though, the data from NSIDC shows the summer melt is running near 2007’s record low extent, and still dropping.  Another independent analysis (using a different satellite and sensor) of arctic ice is done by the …

Tropics Are Heating Up- Planet Already Is

  A strong tropical wave off of Africa is looking as if it may develop into the seasons first Cape Verde type tropical system. The storms that develop near the Cape Verde Islands do not usually start until late in Summer and can become hurricanes that last for many days.  A close up view of the system farthest east shows what may be some circulation and the NHC forecaster is …

Weekend Digest- Tropical Trouble, Melting Ice and Mainstream Scientists Speak Out

    This is the weekly digest of Earth science news that I said would be posted every Friday. OK, so it’s a bit late but it is still the weekend and what follows is a summary of interesting tidbits I’ve seen this week on other science blogs etc. We begin with the great 2011 drought/heat wave: Deep Fried Texans Austin, Texas is happy to wave so long to July. …

Heat Wave At The North Pole Speeds Up The Big Melt

  There was update from the National Snow and Ice Data Center this week regarding the summer melt of Arctic Ocean sea-ice. It’s beginning to look as if a new record low in ice extent is possible by the time the melting ends in early September, passing the all time low set in 2007. Here is the update from NSIDC: Overview of conditions As of July 17, 2011, Arctic sea …

Weekend Climate Tid Bits

It’s been an interesting week or so in the climate science arena with papers on climate change in the AGU journal Geophysical Research Letters and Nature. Then there’s that study put together by Dr. Richard Muller to “check” the temperature rise that NOAA/NASA and the Hadley Centre (UK Met. Office) have reported. If you’re still in the rapidly dwindling group of those who think we are not facing a very …
