In 2013, the vast majority of worldwide climate indicators—greenhouse gases, sea levels, global temperatures, etc.—continued to reflect trends of a warmer planet, according to the indicators assessed in the State of the Climate in 2013 report, released online today by the American Meteorological Society.

Scientists from NOAA’s National Climatic Data Center in Asheville, N.C., served as the lead editors of the report, which was compiled by 425 scientists from 57 countries around the world (highlights, visuals, full report). It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments on air, land, sea, and ice.

“These findings reinforce what scientists for decades have observed: that our planet is becoming a warmer place,” said NOAA Administrator Kathryn Sullivan, Ph.D. “This report provides the foundational information we need to develop tools and services for communities, business, and nations to prepare for, and build resilience to, the impacts of climate change.”

The report uses dozens of climate indicators to track patterns, changes, and trends of the global climate system, including greenhouse gases; temperatures throughout the atmosphere, ocean, and land; cloud cover; sea level; ocean salinity; sea ice extent; and snow cover. These indicators often reflect many thousands of measurements from multiple independent datasets. The report also details cases of unusual and extreme regional events, such as Super Typhoon Haiyan, which devastated portions of Southeast Asia in November 2013.

NOAA’s policy of notifying — but not necessarily citing — speeding vessels in protected areas along the East Coast was effective in lowering their speeds through these sensitive areas, protecting the critically endangered North Atlantic right whales from ship collisions, while keeping punitive fines to mariners to a minimum, according to a new study.

A NOAA regulation, instituted in December 2008, requires vessels 65 feet or greater in length to travel at speeds of 10 knots or less in areas seasonally occupied by the critically endangered North Atlantic right whale.

The NOAA-led study looked the compliance with speed regulations by 8,009 individual vessels that made more than 200,000 trips between November 2008 and August 2013, mostly in areas where the endangered whales are known to travel. Some were remotely monitored by radio signals sent from the vessels.
Virtually all ships received notification of the speed regulations. The owners or operators of 437 of these ships received non-punitive notifications of violations and were reminded of the regulation, or cited after they were observed violating the restrictions. Twenty-six of them received citations and were fined.

Compliance with the regulation was low at the beginning of the regulatory period but steadily improved, according to the study. Vessels that received fines or citations later showed improved compliance. Informational letters issued by NOAA’s Office of Law Enforcement, monthly public summaries of vessel operations, and direct at-sea radio contact also were effective in keeping the vessels in compliance with the law.

NOAA predicts near-normal or below-normal 2014 Atlantic hurricane season

In its 2014 Atlantic hurricane season outlook issued today, NOAA’s Climate Prediction Center is forecasting a near-normal or below-normal season.

The main driver of this year’s outlook is the anticipated development of El Niño this summer. El Niño causes stronger wind shear, which reduces the number and intensity of tropical storms and hurricanes. El Niño can also strengthen the trade winds and increase the atmospheric stability across the tropical Atlantic, making it more difficult for cloud systems coming off of Africa to intensify into tropical storms.

The outlook calls for a 50 percent chance of a below-normal season, a 40 percent chance of a near-normal season, and only a 10 percent chance of an above-normal season. For the six-month hurricane season, which begins June 1, NOAA predicts a 70 percent likelihood of 8 to 13 named storms (winds of 39 mph or higher), of which 3 to 6 could become hurricanes (winds of 74 mph or higher), including 1 to 2 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher).

These numbers are near or below the seasonal averages of 12 named storms, six hurricanes and three major hurricanes, based on the average from 1981 to 2010. The Atlantic hurricane region includes the North Atlantic Ocean, Caribbean Sea and Gulf of Mexico.

NOAA — El Niño-Southern Oscillation (ENSO) Diagnostic Discussion

The model predictions of ENSO for this summer and beyond are indicating an increased likelihood of El Niño compared with those from last month. Most of the models indicate that ENSO-neutral (Niño-3.4 index between -0.5oC and 0.5oC) will persist through part of the remainder of the Northern Hemisphere spring 2014 (Fig. 6), most likely transitioning to El Niño during the summer. There remains uncertainty as to exactly when El Niño will develop and an even greater uncertainty as to how strong it may become. This uncertainty is related to the inherently lower forecast skill of the models for forecasts made in the spring. While ENSO-neutral is favored for Northern Hemisphere spring, the chance of El Niño increases during the remainder of the year, exceeding 65% during the summer (click CPC/IRI consensus forecast for the chance of each outcome).

January Global Temperature Fourth Highest on Record
Source: NOAA

According to NOAA scientists, the globally-averaged temperature over land and ocean surfaces for January 2014 was the highest since 2007 and the fourth highest for January since reliable record keeping began in 1880. It also marked the 38th consecutive January and 347th consecutive month (almost 29 years) with a global temperature above the 20th century average. The last below-average January global temperature was January 1976 and the last below-average global temperature for any month was February 1985.

Most areas of the world experienced warmer-than-average monthly temperatures, with the most notable warmth across Alaska, western Canada, southern Greenland, south-central Russia, Mongolia, and northern China. Parts of southeastern Brazil and central and southern Africa experienced record warmth, contributing to the warmest January Southern Hemisphere land temperature departure on record at 2.03°F (1.13°C) above the 20th century average. Temperature departures were below the long-term average across the eastern half of the contiguous U.S, Mexico, and much of Russia. However, no regions of the globe were record cold.

The 2013 Atlantic hurricane season, which officially ends on Saturday, Nov. 30, had the fewest number of hurricanes since 1982, thanks in large part to persistent, unfavorable atmospheric conditions over the Gulf of Mexico, Caribbean Sea, and tropical Atlantic Ocean. This year is expected to rank as the sixth-least-active Atlantic hurricane season since 1950, in terms of the collective strength and duration of named storms and hurricanes.

The nation’s 28 National Estuarine Research Reserves (NERR) are experiencing the negative effects of human and climate-related stressors according to a new NOAA research report from the National Ocean Service. Results of the new national study, Climate Sensitivity of the National Estuarine Research Reserve System, point to three East Coast located reserves, Sapelo Island NERR (GA), ACE Basin NERR (SC) and Waquoit Bay NERR (MA), and one on the California-Mexico border, Tijuana River NERR (CA), as the most sensitive to climate change.

Researchers determined the extent of relative climate sensitivity in the reserves by looking at five factors: social, biophysical, and ecological sensitivity, and exposure to temperature change and sea level rise.

High social sensitivity to climate change was indicated where there is higher employment within natural resource-dependent industries, lower per capita income and median home values, higher percentages of minority populations, and a higher percentage of individuals lacking a high school education.
• Social sensitivity to climate change was generally highest in the southern portions of the East and West coasts of the U.S., the Gulf of Mexico and Alaska.

Biophysical sensitivity summarizes each reserve’s relationship between annual spring atmospheric temperature and rainfall data and water quality factors such as water temperature, dissolved oxygen and pH.
• Temperature change exposure risk was greatest for reserves located in the Great Lakes, Gulf of Mexico, Mid- Atlantic, and Northeast regions of the country, while reserves in the Gulf of Mexico, parts of the Mid-Atlantic, Southeast, California, and Oregon showed the greatest risk of seal level rise exposure.

NOAA, partners predict possible record-setting dead zone for Gulf of Mexico

NOAA, partners predict possible record-setting dead zone for Gulf of Mexico

Source: NOAA

Scientists are expecting a very large “dead zone” in the Gulf of Mexico and a smaller than average hypoxic level in the Chesapeake Bay this year, based on several NOAA-supported forecast models.

NOAA-supported modelers at the University of Michigan, Louisiana State University, and the Louisiana Universities Marine Consortium are forecasting that this year’s Gulf of Mexico hypoxic “dead” zone will be between 7,286 and 8,561 square miles which could place it among the ten largest recorded. That would range from an area the size of Connecticut, Rhode Island and the District of Columbia combined on the low end to the New Jersey on the upper end. The high estimate would exceed the largest ever reported 8,481 square miles in 2002 .

Hypoxic (very low oxygen) and anoxic (no oxygen) zones are caused by excessive nutrient pollution, often from human activities such as agriculture, which results in insufficient oxygen to support most marine life in near-bottom waters. Aspects of weather, including wind speed, wind direction, precipitation and temperature, also impact the size of dead zones.

The Gulf estimate is based on the assumption of no significant tropical storms in the two weeks preceding or during the official measurement survey cruise scheduled from July 25-August 3 2013. If a storm does occur the size estimate could drop to a low of 5344 square miles, slightly smaller than the size of Connecticut.

The National Climatic Data Center (NCDC) is the Nation’s Scorekeeper in terms of addressing severe weather/climate events in their historical perspective. As part of its responsibility of monitoring and assessing the climate, NCDC tracks and evaluates climate events in the U.S. and globally that have great economic and societal impacts. NCDC is frequently called upon to provide summaries of global and U.S. temperature and precipitation trends, extremes, and comparisons in their historical perspective. Found here are the weather/climate events that have had the greatest economic impact from 1980 to 2012. The U.S. has sustained 144 weather/climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2013). The total cost of these 144 events exceeds $1 trillion.

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), of which 7 to 11 could become hurricanes (winds of 74 mph or higher), including 3 to 6 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher).

These ranges are well above the seasonal average of 12 named storms, 6 hurricanes and 3 major hurricanes.

NOAA presented to the U.S. Coast Guard today a new report that finds that 36 sunken vessels scattered across the U.S. seafloor could pose an oil pollution threat to the nation’s coastal marine resources. Of those, 17 were recommended for further assessment and potential removal of both fuel oil and oil cargo.

The sunken vessels are a legacy of more than a century of U.S. commerce and warfare. They include a barge lost in rough seas in 1936; two motor-powered ships that sank in separate collisions in 1947 and 1952; and a tanker that exploded and sank in 1984. The remaining sites are 13 merchant marine ships lost during World War II, primarily along the Atlantic Seaboard and Gulf of Mexico. To see a list of the ships and their locations, visit:

The report, part of NOAA’s Remediation of Underwater Legacy Environmental Threats (RULET) project, identifies the location and nature of potential sources of oil pollution from sunken vessels. Knowing where these vessels are helps oil response planning efforts and may help in the investigation of reported mystery spills–sightings of oil where a source is not immediately known or suspected.

The latest State of the Climate National Overview report from the National Oceanic and Atmospheric Administration (NOAA) and NOAA’s National Climatic Data Center reveals that 2012 was the United States’ warmest year on record by a wide margin.

According to the latest statistics from NOAA’s National Climatic Data Center, the average temperature for the contiguous United States for 2012 was 55.3° Fahrenheit, which was 3.2° Fahrenheit above the twentieth-century average and 1.0° Fahrenheit above the previous record from 1998. Every state in the contiguous United States had an above-average annual temperature for 2012. The year consisted of the fourth-warmest winter, a record-warm spring, the second-warmest summer, and a warmer-than-average autumn.

2012 marked the warmest year on record for the contiguous United States with the year consisting of a record warm spring, second warmest summer, fourth warmest winter and a warmer-than-average autumn. The average temperature for 2012 was 55.3°F, 3.2°F above the 20th century average, and 1.0°F above 1998, the previous warmest year.

The average precipitation total for the contiguous U.S. for 2012 was 26.57 inches, 2.57 inches below average, making it the 15th driest year on record for the nation. At its peak in July, the drought of 2012 engulfed 61 percent of the nation with the Mountain West, Great Plains, and Midwest experiencing the most intense drought conditions. The dry conditions proved ideal for wildfires in the West, charring 9.2 million acres — the third highest on record.

The U.S. Climate Extremes Index indicated that 2012 was the second most extreme year on record for the nation. The index, which evaluates extremes in temperature and precipitation, as well as landfalling tropical cyclones, was nearly twice the average value and second only to 1998. To date, 2012 has seen 11 disasters that have reached the $1 billion threshold in losses, to include Sandy, Isaac, and tornado outbreaks experienced in the Great Plains, Texas and Southeast/Ohio Valley.

Busy 2012 hurricane season continues decades-long high activity era in the Atlantic

November 30 marks the end of the 2012 Atlantic Hurricane season, one that produced 19 named storms, of which 10 became hurricanes and one became a major hurricane. The number of named storms is well above the average of 12. The number of hurricanes is also above the average of six, but the number of major hurricanes is below the average of three.

Based on the combined number, intensity, and duration of all tropical storms and hurricanes, NOAA classifies the season as above-normal. 2012 was an active year, but not exceptionally so as there were 10 busier years in the last three decades.

This season marks the second consecutive year that the mid-Atlantic and Northeast suffered devastating impacts from a named storm. Sandy, and Irene last year, caused fatalities, injuries, and tremendous destruction from coastal storm surge, heavy rainfall, inland flooding, and wind. Storms struck many parts of the country this year, including tropical storms Beryl and Debby in Florida, Hurricane Isaac in Louisiana, and Post-tropical Cyclone Sandy in New Jersey.
