Ocean currents likely to carry oil along Atlantic coast | UCAR - 0 views

  • The research was supported in part by the National Science Foundation, NCAR’s sponsor. The results were reviewed by scientists at NCAR and elsewhere, although not yet submitted for peer-review publication.

      this is a sticky note on my highlight about research
  • The computer simulations indicate that, once the oil in the uppermost ocean has become entrained in the Gulf of Mexico’s fast-moving Loop Current, it is likely to reach Florida's Atlantic coast within weeks. It can then move north as far as about Cape Hatteras, North Carolina, with the Gulf Stream, before turning east. Whether the oil will be a thin film on the surface or mostly subsurface due to mixing in the uppermost region of the ocean is not known.

Record sea surface temperatures driven by global warming - 0 views

  • In a Congressional briefing on 30 June 2010, hurricane expert Greg Holland of the National Center for Atmospheric Research (NCAR) said the potential for a disastrous 2010 hurricane season reflects not just natural variability but also climate change.  He explained that record high sea surface temperatures in the tropical Atlantic were one of the principal factors behind the dire forecast, and that rising atmospheric concentrations of greenhouse gases may account for roughly half of the anomalous warmth.  He warned that "we’re looking at potentially a doubling of major hurricanes in the next 20 to 30 years" as a result of global warming.  Holland, Director of NCAR's Earth System Laboratory, made his remarks as a member of a panel on Hurricanes and Oil Will Mix: Managing Risk Now. 
  • A month before the panel's briefing, the National Oceanic and Atmospheric Administration (NOAA) issued on 27 May its 2010 Atlantic Hurricane Season Outlook. NOAA said there was a 70% chance that the Atlantic hurricane season would see 14-23 named storms, 8-14 hurricanes, and 3-7 major hurricanes.
  • Among the factors underlying its outlook, NOAA cited warm Atlantic Ocean surface waters, which in May were for the fourth month in a row at record high temperatures for the month:  "Sea surface temperatures [SSTs] are expected to remain above average where storms often develop and move across the Atlantic. Record warm temperatures – up to four degrees Fahrenheit above average – are now present in this region."

  • "There has not been a seasonal forecast of 23 storms put out for this country before," said Holland.  Like forecasters from NOAA and elsewhere (see More pre-season predictions of a very active Atlantic hurricane season, at the WunderBlog for a summary of forecasts), Holland cited high SSTs as a principal factor underlying his assessment. The SSTs during the first month of the hurricane season did nothing to diminish concerns.  As the figure below indicates, high SSTs characterized the tropical Atlantic in June, with many areas again seeing record high temperatures for the month. 
  • "So what’s happening?" asks Holland.  "Well it’s a combination of global warming and natural variability."
  • This is consistent with research results published in Geophysical Research Letters on 29 April 2010.  In Is the basin-wide warming in the North Atlantic Ocean related to atmospheric carbon dioxide and global warming?, Chunzai Wang and Shenfu Dong of NOAA's Atlantic Oceanographic and Meteorological Laboratory, conclude that "both global warming and AMO [Atlantic multidecadal oscillation] variability make a contribution to the recent basin-wide warming in the North Atlantic and their relative contribution is approximately equal."

Commodity futures rise on climate change impacts - 0 views

  • Oil is not the only commodity that has been roaring ahead this year. Precious metals are in a major bull market as are corn, wheat, rice, and soybeans. In fact, while the fall in the dollar is part of the commodity futures bull markets story you can not get away from the fact that rapidly developing economies in a number of nations and changes in weather patterns caused by climate change are important factors in driving futures prices.

Poison ivy crops at record levels in Chicago, East spurred by elevated CO2 - 0 views

  • Bolstered by mild winters and heavy spring rains, the poison ivy creeping across the Chicago landscape this summer is at bumper crop levels.The abundance of poison ivy and other invasive plants proliferating in Illinois and across much of the nation this year is a symptom of a scenario more serious than an itchy red rash, experts say.Elevated CO2 levels in the atmosphere, although destructive to many plant species, are proving a boon for adaptive weeds such as poison ivy, said Lewis Ziska, a federal plant physiologist.
  • "We are up to our arms in poison ivy this summer," said Ziska, with the USDA's Agricultural Research Service in Beltsville, Md. The higher CO2 levels, he said, also are contributing to an increasing abundance of kudzu, the legendary vine once limited to the South but was discovered lurking in central Illinois and as far north as Canada. Dr. Paul Epstein, associate director for the Center for Health and the Global Environment at Harvard Medical School, said recent studies show that poison ivy is not only more prevalent across the U.S. but more toxic, too. The rise in CO2 levels strengthens an oil in the plant that triggers itchy havoc when it touches the skin, he said. The heavy rains, warmer temperatures and rising CO2 levels that have disturbed plant chemistry also have increased pollen counts, leading to higher rates of asthma and allergies. "It's not an accident we're having this perfect storm," said Epstein. "Pests and pathogens thrive in extreme events, like floods or droughts. We need to stabilize the climate by reducing fossil fuel emissions dramatically." John Masiunas, an associate professor in the Department of Crop Sciences at the University of Illinois Urbana- Champaign, said he is unaware of any quantitative data tracking an increase in poison ivy taking root across the state. But, he said, "it makes perfect sense that higher CO2 levels will make these plants more efficient." The plant has "a survivor's ability" to grow in a variety of environments, Masiunas said, adding that climate change is also detrimental to endangered species such as native thistles and orchids that require specific soils and pollinators to thrive. "When climate change occurs … it is poor for these plants and contributes to the extinction of the species," Masiunas said. "When endangered plants are competing in an agricultural ecosystem, they start losing, and plants like poison ivy start doing better."
