Iceberg Tuesday


While Arctic ice is melting at a record pace, a team of NASA-led researchers say they can explain why Antarctic sea ice has been edging in the opposite direction. That paradox has puzzled scientists for years and given climate-change deniers fodder to dispute global warming.

The group found that the icy winds blowing off Antarctica, as well as a powerful ocean current that circles the frozen continent, are much larger factors in the formation and persistence of Antarctic sea ice than changes in temperature.

The mighty Southern Ocean Circumpolar Current prevents warmer ocean water from reaching the Antarctic sea ice zone, helping to isolate the continent. The winds within that ice zone keep the water extremely cold, enabling the sea ice cover to grow in recent years even as global temperatures have risen markedly.

The findings are based on satellite readings of Antarctic sea ice movement and thickness, as well as new, detailed interpretations of charts showing the shape of the sea bottom around Antarctica. They were published online this month in the journal Remote Sensing of Environment.

    Frosty bits on the top and bottom of the planet kept at bay by the Sun, more Sun less frosty bits.

    I blame it on the Wobble Factor

    Clear and 89 °F.

    The deluxe townhouses under construction across Stadium Way are proceeding so slowly that I fail to understand how the units can be ready for fall semester.

    I’m working on the little computer cuz I just got done with a major software overhaul, getting rid of useless programs created by the silicone valley gurus that were interfering with progress.
    Clips right along now just like it’s bigger brethren. Old bookmarks will yield some interesting posts.

    I’m ready for some fresh meat anyway.

    Back on the larger brethren, I keep the little guy around in case this one craps out.

    Both computers slow on the upload speed, took forever to get the little one to run right to even check with Mr.BIG, next router issues need to be checked by the friendly provider tomorrow.

    About 24 minutes in the warmth to the Black Cypress for Alaskan halibut dinner. Pricey.

      After a delicious bread pudding with ice cream for dessert, a stick walk, mostly, up the p. stairs to Sloan. Total taken as 41 minutes today.

      Day 3: 110+41=151 minutes, already the desired weekly minimum.
