Blue Holes

Great Blue Hole off the coast of Belize.

Blue Holes are caves or underwater sinkholes that are roughly circular, steep depressions. They are so named for the dramatic contrast between the dark blue, deep waters of their depths and the lighter blue of the shallow waters around them.  There several blue holes around the world, and they're typically found in low-lying coastal regions. The best examples are in Belize, the Bahamas, Guam, in the Great Barrier Reef off the coast of Australia, and in the Red Sea in Egypt. Dean's Hole, in a bay west of Clarence Town on Long Island, Bahamas, is the deepest blue hole in the world, at 663 feet deep.

NOAA recently produced an interesting map showing when the hottest day of the year is likely to occur in the contiguous U.S. Complimenting this map is one produced by Brian Brettschneider of Borealis Scientific, LLC, which illustrates the date of summer’s midpoint (peak of summer average temperatures) which was reproduced in my blog posted last August. Brian has also produced maps of such for the Fall, Winter and Spring seasons. There is also some other great material from Brian herein.

Some mountainous areas of southern Japan are predicted to receive 20 - 28" of rain from Neoguri. With soils already saturated from a week of heavy rains prior to Neoguri's arrival, damaging flooding is expected.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
