- Extreme Weather events in US during 2012 --
Last week NOAA reported that 11 weather and climate extreme events
occurred during 2012 produced at least $1 billion in losses. These
events included seven severe weather/tornado outbreaks, two tropical
cyclones involving hurricanes or tropical storms that made landfall in
the United States and a year-long major drought with associated
wildfires. In addition, these eleven events appear to have caused 349
deaths, with Sandy claiming 131 lives and the summer-long heat wave and
associated drought causing over 123 direct deaths; an estimate of the
excess mortality due to heat stress is remains unknown. NOAA estimates
that the grand total in losses due to all weather events and climate
episodes in 2012 should exceed last year's total, surpassing $60
billion. Most of the monetary losses would be from the persistent,
widespread drought and from Super Storm Sandy. [NOAA

- Review of Canada's top ten weather stories in 2012
-- During the last week, meteorologists with Environment
Canada released a list of what they considered the top ten weather
events across Canada during this calendar year of 2012. Some of these
stories included the unseasonably warm weather that persisted
throughout most of the year, the active Atlantic hurricane season, the
major spring flooding in British Columbia and the ice melt in the
Arctic sea ice. [Environment

Ocean in the News:
- Eye on the tropics -- The only
organized tropical cyclone activity during the last week was found in
the
South Pacific basin, where Cyclone Evan intensified to a category 4
cyclone on the Saffir-Simpson Scale as it passed Fiji at the start of
the week. More than 3500 people on Fiji were evacuated to emergency
shelters due to Evan, which was reported to be the biggest tropical
cyclone to affect the Pacific island nation in 20 years. Winds
associated with Evan gusted to 170 mph along the northwest coasts of
Fiji's main islands and a strong storm surge was also produced.
Earlier, four people had been killed and thousands of home destroyed on
nearby Samoa. [NBC
World News] By late in the week, Cyclone Evan had become a
remnant low pressure system over the waters of the South Pacific to the
northeast of New Zealand. For satellite images and additional
information on Cyclone Evan, please see the NASA
Hurricane Page.
- A global review of November 2012 temperatures --
Preliminary analysis of temperature data by scientists at
NOAA's National Climatic Data Center indicates that the worldwide
combined ocean and land surface temperature for November 2012 ranked as
the fifth highest global November surface temperature since a
sufficiently dense and reliable network began in 1880. They also found
that both the global ocean surface temperature and the global land
surface temperatures were both the sixth highest readings for any
November on record. The scientists also noted that the ten warmest
Novembers have occurred during the last 12 years, including this past
month. Furthermore, they reported that the combined land and ocean
surface temperature for the globe during the Northern Hemisphere autumn
(September-November 2012) was the second highest for all boreal autumn
seasons going back to 1880. However, when averaged over the first
eleven months of 2012, the combined ocean and land surface temperature
was the eighth highest January through November average in 133 years of
record. ENSO-neutral conditions continued in the eastern equatorial
Pacific Ocean during November 2012 and could extend through Northern
Hemisphere winter and into spring, thereby affecting global ocean
temperatures in the upcoming months. [NOAA/NCDC

- Review of NOAA research activities around the
globe in 2012 -- During the last week NOAA's Office of
Oceanic and Atmospheric Research (OAR) provided a list of highlights of
the scientific research the agency has conducted around the globe
during the calendar year of 2012 in an effort to advance weather
forecasting, climate prediction, environmental modeling, ocean
exploration and coastal protection. Some of the OAR research activities
during 2012 included improved techniques to model atmospheric radiation
transport following the Japanese nuclear accident; airborne mercury
studies; influence of climate patterns on the extreme tornado season
across the nation in 2011; monitoring of Hurricane Sandy; monitoring of
greenhouse gases and stratospheric ozone; assessment of endangered
marine species threatened by changing climate and ocean acidity;
successful habitat reconstruction on the Great Lakes. [NOAA

- New England offshore areas to reopen for several
fisheries -- NOAA Fisheries officials recently announced that
they will reopen sections of Georges Bank in the waters off the New
England coast to fishing for Atlantic surfclam and ocean quahog
beginning in January. These fisheries had been closed to harvesting for
22 years because of high toxin levels that have now diminished. [NOAA

- Deepwater gas seeps discovered off US Atlantic
coast -- NOAA ocean explorers have discovered as many as 17
deepwater gas plumes emanating from the North Atlantic Ocean floor off
the Middle Atlantic coast of the United States. These explorers used
imagery from an advanced multi-beam sonar unit built into the hull of
NOAA Ship Okeanos Explorer to discover and map
these seafloor seep locations. [NOAA
News]
- Warming of planet during instrumental period
confirmed by independent evidence -- A team of researchers
from NOAA's National Climatic Data Center, the University of South
Carolina, the University of Colorado and Switzerland's University of
Bern has reconstructed a "proxy" temperature record for the last 130
years that has been compiled from several independent
temperature-sensitive proxy indicators such as ice cores, old coral and
sediment layers extracted from oceans and lakes. These researchers have
found that this proxy temperature record drawn from 173 independent
proxy datasets reveals a pattern of increased global temperatures
between 1880 and 1995 that is comparable to the trend seen in the
instrumental temperature record obtained from thermometers. They also
claim that their findings resolve some of the uncertainty associated
with thermometer records, including variations in instrumentation,
shifts in station location and changes surrounding land use. [NOAA

- Map shows locations of Great Lakes restoration
challenges -- A team of US and Canadian researchers known as
the Great Lakes Environmental Assessment and Mapping (GLEAM) project
have produced a map that quantitatively identifies those areas around
the North American Great Lakes susceptible to "environmental
stressors." This environmental stress map should provide federal and
regional officials with sufficient scientific information to manage the
Great Lakes in sustainable fashion. [University
of Michigan News Service]
- Large dock and other tsunami debris reach
Washington coast -- Early last week the US Coast Guard found
a large dock structure that had washed up on the coast of Washington's
Olympic National Park. Although not confirmed, this dock may have been
a piece of debris that floated across the North Pacific following the
March 2011 tsunami in Japan. [KING5]
- Animals found to contribute to seagrass dispersal
-- Researchers at the Virginia Institute of Marine Science
have found that small animals appear to help disperse seeds from a type
of seagrass called eelgrass in the eelgrass beds around Chesapeake Bay.
This discovery could help in the restoration efforts in the Bay, the
nation's largest estuary, and in other coastal ecosystems. [Virginia
Institute of Marine Science]
- Climate change is shown to have major effects on
ecosystems and species -- A technical report on biodiversity
and ecosystems prepared by more than 60 federal, academic and other
scientists, including the lead authors from the U.S. Geological Survey,
the National Wildlife Federation and Arizona State University in Tempe
will be used as scientific input for the 2013 Third National Climate
Assessment. This report, entitled Impacts of Climate Change
on Biodiversity, Ecosystems, and Ecosystem Services, will
show that plant and animal species are shifting their geographic ranges
and the timing of their life cycles at faster rates than even a few
years ago as a consequence of changing climate conditions. [USGS

Historical Events:
- 25 December 1492...The Santa Maria, one
of the ships that Christopher Columbus used in his historic
trans-Atlantic voyage, landed at the Dominican Republic.
- 25 December 1974...Tropical Cyclone Tracy (a hurricane in
the waters surrounding Australia) made landfall near Darwin, Northern
Territory, Australia. Excellent warnings kept the death toll to between
50 and 60, with more than 20,000 people evacuated in the week following
the storm. Some areas were totally devastated. Peak wind speeds reached
exceeded 174 mph. (The Weather Doctor) (Accord's Weather Calendar)
- 26-31 December 1993...The Sydney to Hobart Yacht Race off
Australia was plagued by hurricane-force wind gusts in excess of 74 mph
and 33 foot high seas. Of 104 starters, only 37 yachts finished the
race. On the 28th, one yacht owner spent five
hours in the water after being swept overboard. (Accord's Weather
Calendar)
- 26 December 2004...A massive earthquake measuring 9.0 on
the Richter magnitude scale approximately 100 miles off the western
coast of Sumatra created a tsunami that caused devastation in Sri
Lanka, India, Indonesia, Thailand, Malaysia, The Maldives and many
other areas around the rim of the Indian Ocean. The death toll is
currently estimated at more than 300,000. Officials say the true toll
may never be known, due to rapid burials. Indonesia was worst affected
with as many as 219,000 people killed. (Wikipedia)
- 28 December 1857...The light was first illuminated in the
Cape Flattery Lighthouse, located on Washington State's Tatoosh Island
at the entrance to the Strait of Juan de Fuca. "Because of Indian
trouble it was necessary to build a blockhouse on Tatoosh Island before
even commencing the construction of the lighthouse. Twenty muskets were
stored in the blockhouse, and then the lighthouse work began." (USCG
Historian's Office)
- 28 December 1903...An Executive Order extended the
jurisdiction of the Lighthouse Service to the non-contiguous territory
of the Hawaiian Islands. (USCG Historian's Office)
- 28 December 1908...An early morning earthquake under the
Straits of Messina leveled cities in Sicily and southern mainland
Italy, as well as producing a tsunami with 40-foot waves that inundated
coastal communities. This earthquake, estimated to by a magnitude 7.5
on the Richter scale, and the resulting tsunami killed an estimated
100,000 people. Long stretches of coastline sunk into the Messina
Straits and disappeared from view. A steady rain also added to the woes
of the survivors. (The History Channel)
- 29 December 1897...Congress prohibited the killing of fur
seals in the waters of the North Pacific Ocean. (US Coast Guard
Historian's Office)
- 30 December 1972...The 86-foot high wave measured by the
ship Weather Reporter was the world's highest
measured wave. The wave was measured in the North Atlantic Ocean at 59
degrees North latitude and 19 degrees West longitude. (Accord's Weather
Calendar)
