climate change impact USA heat wave temperature

shared by Hunter Cutting on 08 Jul 10 - Cached
  • New daily high temperature records were set in many cities, with June 2010 ranking as the hottest June on record for Delaware, New Jersey, and North Carolina.
  • The unusual warmth in the highly populated South and Southeast resulted in the second highest June REDTI value in the 116-year record. For the first half of 2010, large footprints of extreme wetness (more than three times the average footprint), warm minimum temperatures ("warm overnight lows"), and areas experiencing heavy 1-day precipitation events resulted in a Climate Extremes Index (CEI) that was about 6 percent higher than the historical average.
  • The nationally-averaged temperature for June was much warmer than normal. A deep layer of high pressure dominated much of the eastern United States

  • The Southeast, South and Central regions experienced their second, fifth and seventh warmest June on record, respectively.
  • Record-warm June temperatures were observed in Delaware, New Jersey and North Carolina (tied), where each had average temperatures 5 to 6 degrees F above the long-term mean. Many other states ranked in their top ten based on 116 years of data.
  • Midway through 2010, four New England states (Maine, New Hampshire, Vermont and Rhode Island) have experienced their warmest January-June period on record. Eight other states in the Northeast and Great Lakes areas had a top-ten warm such period.
  • Persistent warmth made the year's second quarter (April-June) much warmer than normal for every state east of the Mississippi River, and several to its west. Louisiana and ten Atlantic Seaboard states (Maine, New Hampshire, Massachusetts, Delaware, Rhode Island, Connecticut [tied], New Jersey, Maryland, Virginia, and North Carolina) had a record-warm second quarter. In all, twenty states had their warmest or second-warmest such period on record. The warmth in these areas contributed to both the Northeast and Southeast climate regions' warmest April-June period.

  • Once again, Philadelphia faces an especially hot summer
  • It has been hot for days, for weeks, and for that matter, remarkably often in the last 23 years. In the period of record dating to 1874, officially eight of the 10 warmest summers in Philadelphia have occurred since 1988.
  • This latest heat surge continues an extraordinarily warm period that took hold in March, right after the historic snows disappeared. In New Jersey, the March 1-June 1 period - the meteorological spring - was the warmest statewide on record, said David Robinson, a Rutgers University professor who is the state climatologist.

climate change impact USA heat wave temperature Washington DC Philadelphia New Jersey

  • Having just completed the warmest spring on record, Washington, DC, and other cities in the eastern United States are enduring a record-breaking heat wave that is consistent with climate change. Last week’s temperatures in Washington D.C. broke a century-old record and forecasters expect this month to be the hottest June on record for the area. These patterns fit the long-term trends of more frequent heat waves driven by climate change
  • Characteristics of the current heat wave in the Washington, DC area include record daytime highs, record high overnight lows, and the long string of days above 90 degrees, all of which are consistent with the trends in the U.S. driven by climate change. The back-to-back heat waves experienced in Philadelphia this June also reflect the long-term global warming trend, as do the record-breaking average temperatures witnessed this past spring in Washington D.C., Maryland, Pennsylvania, and New Jersey.

climate change impact USA east coast heat wave temperature

  • The eastern U.S. cooked for another day Wednesday as unrelenting heat again sent thermometers past 100 degrees in urban "heat islands," buckled roads, slowed trains and pushed utilities toward the limit of the electrical grid's capacity.
  • Records fall again in East as heat swelters on
  • Philadelphia hit 100 degrees for second straight day, breaking a record of 98 degrees set in 1999. Baltimore hit 100 for the third straight day and Newark, N.J., hit triple digits for the fourth straight day. New York's Central Park was at 99 degrees at 2 p.m.

  • Scattered power outages affected customers up and down the coast and usage approached record
  • levels. In the Washington, D.C., area, nearly 1,000 customers were without power Wednesday, while New Jersey's largest utility, Public Service Electric & Gas, reported about 6,300 customers without power. Consolidated Edison in New York said it was working to restore power to about 6,300 customers, down from outages to 18,700 customers Tuesday.
  • The heat also forced nursing homes with power problems to evacuate and buckled highways near Albany and in the Philadelphia area. On New York's Long Island, a radio station was distributing free bottled water to day laborers, while human services workers in Pittsburgh were doing the same for the homeless there.
  • Transportation officials cut the speed of commuter trains in suburban Washington, D.C., and New York when the tracks got too hot. Extreme heat can cause welded rails to bend under pressure. Some New Jersey trains were canceled and rail-riders were advised to expect delays.
  • In Park Ridge, N.J., police evacuated a nursing home and rehabilitation center after an electrical line burned out Tuesday evening. In Maryland, health officials moved all 150 residents out of a Baltimore nursing home whose operators didn't report a broken air conditioner. The state learned of the home's troubles when a resident called 911 Tuesday
  • Residents of two Rhode Island beach towns, Narragansett and South Kingstown, were hit with an added layer of inconvenience: They were banned from using water outdoors and were asked to boil and cool their water before using it. The high temperatures combined with the busy holiday weekend for tourists created higher-than-expected demand, causing water pressure to drop and increasing the chance of contamination.
  • With people cranking up their air conditioners Wednesday, Valley Forge, Pa.-based PJM Interconnection — which operates the largest electrical grid in the U.S. — urged users to conserve electricity as much as possible, especially in the peak afternoon hours. PJM's grid covers about 51 million people in 13 states and the District of Columbia.
  • Meteorologists in some places began calling the current hot stretch a heat wave, defined in the Northeast as three consecutive days of temperatures of 90 or above.

Ocean Ecosystems Transforming Due to Climate Change - 0 views

oceans ecosystems food chain penguins phytoplankton polar krill salps

  • Global climate change is fundamentally disrupting marine ecosystems, especially in the polar oceans, according to two new reviews of scientific research released Thursday in the journal Science.
  • Changes in temperature, ocean acidity and volume are affecting species from phytoplankton — the microscopic marine plants at base of the food chain — to polar bears, which may lose 68 percent of their summer habitat by 2100. "Climate change is affecting an enormously wide range of physical and biological aspects of the ocean," said John Bruno, a University of North Carolina marine ecologist and co-author of one of the reviews. "Once you start tweaking temperature, everything changes." Photosynthesis by phytoplankton is down six percent since the 1980s, and the organisms themselves are getting smaller thanks to warmer temperatures, the review noted.
  • Less plankton means less food for fish, which in turn means less seafood for human consumption. Phytoplankton also absorb carbon dioxide from the air and sequester it at the seafloor when they die and sink to the bottom of the ocean. Fewer phytoplankton could mean more human carbon dioxide emissions stay in the atmosphere, Bruno said, further exacerbating the climate change problem.

  • The "canary in the coalmine" for all of these shifts is the polar oceans, said Oscar Schofield, an oceanographer at Rutgers University in Newark, New Jersey and a co-author of the second review, which focuses on changes at the West Antarctic Peninsula. There, the authors found, temperatures have increased by 6 degrees Celsius in the past 50 years, more than five times the average change worldwide. Phytoplankton blooms are down 12 percent overall. Krill populations — important food for whales, penguins, fish and other large animals — are plummeting, with jellyfish-like organisms called salps, which don't make as good a meal, taking their place.
  • Above the surface, the polar Adélie penguin population has gone from tens of thousands of breeding pairs to just a few thousand, Schofield said. Temperate species of penguin like the Chinstrap and Gintoo are moving into the Adélie’s old turf. Particularly shocking, Schofield said, is how rapidly these changes are occurring. "It's not like it's happening over hundreds of years," he said. "It's happening over decades."
