FRISCO — With sea surface temperatures at a 150-year high off off the mid-Atlantic and New England coastlines, scientists are document significant shifts in the distribution of commercially important marine species, with as-yet uncertain consequences for the entire ecosystem.

Those temperatures reached a record high of 57.2 degrees in 2012, exceeding the record high set in 1951. The average sea surface temperatures in the region — extending from the Gulf of Maine to Cape Hatteras, North Carolina — has typically been lower than 54.3 degrees during the past three decades, according to a NOAA advisory.

FRISCO— No matter which you slice it, the Arctic Ocean is likely to almost free of summer ice by mid-century, and possibly within the next couple of decades. according to a new study by federal scientists.

By comparing three different predictive models, the researchers came up with a range of dates when most of the Arctic Ocean ice will melt away for at least a couple of months during the northern hemisphere summer.

The most aggressive models, which weigh recent trends more heavily, suggest ice-free conditions could come as soon as 2020. Under a second group of models that rely on weighing the future probability of “extreme” but random ice-melt events, the ice-free date is pushed back to 2030. The most conservative predictions are based on global climate models that use global climate models to forecast atmosphere, ocean, land, and sea ice conditions over time. (more…)

Climate: NOAA offers warm and dry spring outlook

The three-month temperature outlook from NOAA indicates warmer than average temperatures across much of the contiguous U.S.

Drought expected to persist across the middle of the country

By Summit Voice

SUMMIT COUNTY — Although March has been cold and snowy across large parts of the U.S., NOAA forecasters say the chances are better than even that temperatures will rebound to above average across much of the continental United States, including drought-stricken areas of Texas, the Southwest and the Great Plains, with little drought relief for those areas. Florida is expected to stay dry as well, but river flooding is possible in some areas, especially North Dakota.

“This outlook reminds us of the climate diversity and weather extremes we experience in North America, where one state prepares for flooding while neighboring states are parched, with no drought relief in sight,” said Laura Furgione, deputy director of NOAA’s National Weather Service. “We produce this outlook to help communities prepare for what’s likely to come in the next few months and minimize weather’s impacts on lives and livelihoods. A Weather-Ready Nation hopes for the best, but prepares for the worst.” (more…)

SUMMIT COUNTY — New satellite technology that can detect lightning inside clouds and track cloud formation may help weather forecasters develop earlier warnings for severe weather, especially tornadoes.

The national average for tornado warnings is 14 minutes. More time would give people in harm’s way a better chance to protect themselves, said the NOAA and NASA scientists working on the new GOES-R technology. The satellites will be able to monitor thunderstorm development with more temporal and spatial detail. (more…)

January brings record warmth to southern hemisphere

Global land and sea surface temps tied with 1995 as ninth-warmest

FRISCO — Southern hemisphere land areas reported their warmest January readings on record, including Australia, where January 2013 was the hottest month ever recorded, according to NOAA climate scientists, who released the global state of the climate report this week. A slide show from the presentation is online here.

The Southern Hemisphere was record warm over land for the second month in a row. Record high monthly temperatures were observed over northeastern Brazil, much of southern Africa, and northern and central Australia. No land areas in the Southern Hemisphere were cooler than average.

While some northern hemisphere land areas reported below-average temperatures for the month, global land and sea surface temperature averaged out to tie with 1995 as the ninth-warmest on record, at .97 degrees above the 20th century average of 53.6 degrees. Even with cooler than average readings in some parts of the northern hemisphere, the average temperature was still 1.48 degrees above average, the 21st-warmest January on record.

Oceans: NOAA report flags illegal fishing by 10 countries

The foreign fishing vessel Marshalls 201 runs from the U.S. Coast Guard Cutter Walnut in September 2006 while still in U.S. waters. After the vessel was stopped and boarded, U.S. Coast Guard personnel determined the Marshalls 201 did not possess the proper permits to fish within U.S. waters and contained approximately 500 metric tons of tuna on board. The vessel and catch were seized and escorted to Guam for prosecution. The owner pled to one count and paid a penalty of $500,000.

Upcoming talks aimed at spurring compliance with treaties

By Summit Voice

SUMMIT COUNTY — As many global fish populations plunge due to unsustainable fishing practices, including illegal catch that ends up in U.S. grocery stores, the federal government  last week announced some small steps to try and curb those practices.

Last week, NOAA submitted a report identifying 10 nations whose fishing vessels engaged in illegal, unreported, and unregulated fishing, or had ineffective measures to prevent the unintended catch of protected species in 2012: Colombia, Ecuador, Ghana, Italy, Mexico, Panama, the Republic of Korea, Spain, Tanzania, and Venezuela.

The U.S. will soon start consultations with those countries to encourage them to take action to address unauthorized fishing and bycatch by their fishermen. Mexico was also identified for ineffective management of the bycatch of North Pacific loggerhead sea turtles, which travel between Japan and Mexico through Hawaiian waters, and are endangered under the U.S. Endangered Species Act.

All 10 nations identified in this year’s report had vessels that did not comply in 2011 and/or 2012 with conservation and management measures required under a regional fishery management organization.

“As one of the largest importers of seafood in the world, the United States has a global responsibility and an economic duty to ensure the fish we import is caught sustainably and legally,” said Sam Rauch, deputy assistant administrator for NOAA’s Fisheries Service. “We look forward to working with these nations to encourage their compliance, and we will continue to work with our partners to detect and combat illegal practices.”

“NOAA’s international fisheries work is critical to the economic viability of U.S. fishing communities and the protection of U.S. jobs,” said Russell Smith, NOAA deputy assistant secretary for international fisheries. “This is about leveling the playing field for fishermen around the world, and IUU fishing represents one of the biggest threats to the U.S. fishing industry. Seafood is a global business, and U.S. fishermen following the rules should not have to compete with those using illegal or unsustainable fishing practices,” Smith said.

According to NOAA, unauthorized and illegal fishing undermines international efforts to sustainably manage and rebuild fisheries and creates unfair market competition for fishermen who adhere to strict conservation measures, like those in the United States. Illegal fishing can devastate fish populations and their productive marine habitats, threatening food security and economic stability. Independent experts have estimated economic losses worldwide from illegal fishing at between $10 billion and $23 billion annually.

All six of the nations identified in the previous 2011 Biennial Report to Congress (Colombia, Ecuador, Italy, Panama, Portugal, and Venezuela) have addressed the instances by taking strong actions like sanctioning vessels, adopting or amending laws and regulations, or improving monitoring and enforcement. Each of these six nations now has a positive certification for their 2011 identified activities. However, a nation positively certified for action taken since the last report may be listed again as engaged in IUU fishing if new issues are identified, as is the case in this report.

If a nation fails to take appropriate action to address the instances of illegal fishing or bycatch activities described in the report, that nation’s fishing vessels may be denied entry into U.S. ports, and imports of certain fish or fish products from that nation into the United States may be prohibited. The United States is second only to China in the amount of seafood it imports. NOAA’s latest figures showed that 91 percent of the 4.7 billion pounds of seafood consumed in the United States in 2011 was imported.

Heat wave and drought, tropical storms and tornadoes top the list

By Summit Voice

FRISCO — Extreme weather events that may be linked with global warming caused at least 239 deaths in 2012, with the biggest loss of life resulting from Hurricane Sandy, which raked the Caribbean before spinning up the East Coast and then coming ashore over New Jersey.

A summer-long heat wave and associated drought that spanned a big portion of North America caused more than 120 direct deaths and possibly more due to heat stress, according to NOAA, which released preliminary data on the year’s billion-dollar extreme weather events. (more…)

SUMMIT COUNTY — Along with the widely reported weather extremes that affected the mid-latitudes were most people live, the remote Arctic also continued to show the effects of climate change in 2012.

Steadily rising global temperatures manifested in the lowest sea ice extent on record in mid-September, dropping nearly 20 percent lower than the previous record set in 2007; the Greenland ice saw a rare widespread melting event and the northern hemisphere snow cover extent also dropped to record low during the spring, according to NOAA’s Arctic Report Card.

SUMMIT COUNTY — To get a better handle on the impacts of incoming “atmospheric rivers,” scientists are installing specialized new coastal observatories at Bodega Bay, Eureka, Pt. Sur and Goleta, California.

The coastal weather stations will measure low altitude winds and the amount of moisture moving ashore — key data that will help forecasters pinpoint how much precipitation is likely to fall during an atmospheric river event.

“California needs to know how and where it might rain or snow, when and where to expect flooding,” said Michael Anderson, Ph.D., state climatologist with the California Department of Water Resources. “The observatories will also help state officials and scientists monitor changes in atmospheric rivers associated with climate change.” (more…)

New data on bycatch prompts federal fisheries managers to drop requirements for turtle excluder devices

By Summit Voice

SUMMIT COUNTY — Federal fisheries managers and biologists continue to grapple with sea turtle conservation — specifically with preventing the bycatch of turtles in commercial fishery operations.

The highly touted turtle excluder devices may not be as effective as hoped in certain types of fishing operations, NOAA biologists said as they announced that they are withdrawing a proposed rule to require turtle excluder devices (TEDs) for skimmer trawls, pusher-head trawls, and wing-net trawls in the southeast shrimp fisheries.
