Here Comes the Atlantic Hurricane Season

gulf of mexico sea surface temperatures

This has been a year of dramatic disasters and weather extremes. From tornadoes to droughts to heat waves, the U.S. has been battered.

Unfortunately, the hurricane season that’s about to get firing may not go any easier on us.

Nobody can say in advance where storms are form to strike or whether they are going to make landfall—but everything is lining up for there to be a lot of them in the Atlantic region, and some very strong ones. As you can see from the figure here, we’re just starting the climb towards the peak of the season, which occurs on September 10.

Sea surface temperatures in the main development region for Atlantic hurricanes (pictured above for the Gulf) are the third hottest they’ve been on record. Everything is lining up for there to be a lot of action: 9-10 hurricanes, and 3-5 major ones, NOAA predicts. There have already been 5 tropical storms, but that’s child’s play compared with what’s likely coming.

Canadian Hotspot Hits 21°C (37.8°F) Above Normal

While world media have been distracted by cold temperatures in Europe (December averages in the U.K. were 5.2°C [9.4°F] below normal), a vast pocket over northeastern Canada has been hitting heights that were not just unprecedented but, until this year, unimaginable.

As Bob Henson reports at the NCAR & UCAR Currents, the Canadian low Arctic has been unseasonably, unreasonably balmy, with the largest anomaly rising to 21°C [37.8°F] above normal. Hudson Bay and the waters around Baffin Island remained open well beyond usual, suggesting that the risk for an extraordinarily low summer ice season is built into the works. (If you look at this map, from Bremen University, you see that even the North Pole was unconvincingly frozen by Jan. 11 of this year.)

Henson looks particularly at the community of Coral Harbour, on the northwest corner of Hudson Bay in Nunavut, where typical January temperatures range from a bone-chilling low of –34°C (–29.2°F) to teeth-chattering "high" of -26°C (–14.8°F). This year, Environment Canada reported that in the first 12 days:

International Scientists Confirm Climate Change is "Undeniable"

An international team of climate scientists led by the National Oceanic and Atmospheric Administration (NOAA) has confirmed that climate change is "undeniable" and clearly driven by the "human fingerprints" of greenhouse gas emissions.  The findings are based on new data that was not reviewed during the most recent 2007 report by the UN Intergovernmental Panel on Climate Change. 

The Financial Times reported today that the NOAA study drew on 11 different indicators of climate, and "found that each one pointed to a world that was warming owing to the influence of greenhouse gases."

The scientists confirmed that seven of the indicators are rising, including air temperature over land, sea-surface temperature, marine air temperature, sea level, ocean heat, humidity, and tropospheric temperature in the “active-weather” layer of the atmosphere closest to the earth’s surface. Four other indicators were declining: Arctic sea ice, glaciers, spring snow cover in the northern hemisphere, and stratospheric temperatures.

The Financial Times quotes Peter Stott, head of climate monitoring at the UK Met Office, stating:

“The whole of the climate system is acting in a way consistent with the effects of greenhouse gases. The fingerprints are clear. The glaringly obvious explanation for this is warming from greenhouse gases.”

Glaringly obvious, unless you are a climate skeptic who denies the facts in favor of touting manufactured scandals like "Climategate" - a mythical tale ginned up by the climate denial machine to further confuse the public about the real dangers of climate change.

Lorne Gunter: Incompetent or Lying? Either Way, Worth Firing

An earlier post of the errors/misrepresentations in a recent Lorne Gunter column in the National Post has attracted a host of comments and a few that further debunk Gunter's passionately inaccurate talking points.

DeSmog reader Dave Clark, for example, offers this:

Yet another whopper from Gunter:

2006 Fifth Warmest Year on Record

Despite beginning the year with a chilling La Niña, the U.S. National Oceanic and Atmospheric Administration (NOAA) advises that 2006 was the fifth-warmest year in recorded history and the hottest year in the U.S.

Check the attached graph and see if you buy the Dr. Bob Carter's contention that global warming ended in 1998.
