A descent into the maelstrom – ‘black hole’ whirlpools seen for the first time in the South Atlantic

More settled science: these whirlpools transport vast amount of water and heat vertically in the ocean, somewhat like hurricanes do for the atmosphere. It is fun to imagine “Trenberth’s missing heat” being sucked down one of these. Via Yahoo News: Satellites have shown two mysterious ‘black hole’ whirlpools in the South Atlantic ocean – ultra…

If storms are worse now, why did they need a sea wall 150 years ago?

From Virginia Tech something that makes you wonder about past storm intensity and the need to protect shorelines from storms coming from the sea. With all the hype surrounding “Superstorm Sandy”, it is interesting to see that 150 years ago, simple engineering made the storm less intense in this one area. Long-forgotten seawall protected New…

NOAA predicts active 2013 Atlantic hurricane season

From NOAA: In its 2013 Atlantic hurricane season outlook issued today, NOAA’s Climate Prediction Center is forecasting an active or extremely active season this year. For the six-month hurricane season, which begins June 1, NOAA’s Atlantic Hurricane Season Outlook says there is a 70 percent likelihood of 13 to 20 named storms (winds of 39 mph or higher),…

On Guemas et al (2013) “Retrospective prediction of the global warming slowdown in the past decade”

I received a number of emails about the newly published Guemas et al (2013) paper titled “Retrospective prediction of the global warming slowdown in the past decade”. It’s paywalled. The abstract is here. It reads: Despite a sustained production of anthropogenic greenhouse gases, the Earth’s mean near-surface temperature paused its rise during the 2000–2010 period1.…

NOAA: ‘2012 was an active [hurricane] year, but not exceptionally so …10 busier years in the last three decades’

An Inconvenient Truth: Sea Surface Temperature Anomalies along Sandy’s Track Haven’t Warmed in 70+ Years

Guest post by Bob Tisdale I was visiting family in the Northeast U.S. when Sandy came ashore, so I was without power for most of last week. Since my return home, I’ve been catching up with all of the nonsense surrounding Hurricane/Extratropical Storm/Hybrid Storm Sandy. There have been hundreds of articles and blog posts that…

Resolving the biases in century-scale sea surface temperature measurements reveals some interesting patterns

This new paper in GRL takes on the well-known buckets-vs-inlets issue (Steve McIntyre also visited the issue several times) related to ship based sea surface temperature measurements and as a result, produces an improved dataset. The results show a surprising period of warming, but not in the time period expected.  How would AGW advocates explain…

The big worry of course is Tropical Storm Isaac, which may collide with Florida this coming week, just in time for the Republican National Convention in Tampa Monday. This from NASA/Goddard Space Flight Center The Atlantic Ocean is kicking into high gear with low pressure areas that have a chance at becoming tropical depressions, storms…

Texas A&M says freshwater hurricanes grow stronger

From Texas A&M University , a claim that fresh water intensifies hurricanes. At first blush, the concept seems wonky to me, as I don’t think there’s much difference between the heat content potential of fresh -vs- saltwater. Though, it might simply be that freshwater deltas have higher temperature of outflowing water to start with, exacerbated…
