Is The Climate changing , or not ?
New York City Could See Up To Six Feet Of Sea Level Rise This Century: Report
Climate change is already impacting New York City with rising temperatures and sea levels, which will only worsen as the century continues, according to a report released Tuesday from a panel of scientific experts.
In its 2015 report, the New York City Panel on Climate Change found that the most populous city in the United States is expected to see more frequent heat waves and extreme precipitation events. This is in line with the national and international trends other leading scientific bodies have observed.
The city's average annual temperatures, measured from Central Park, have risen about 3.4 degrees Fahrenheit since 1900. From 1971 to 2000, the average annual temperature in the city was 54 degrees, and models predict a a 4.1- to 5.7-degree increase by the middle of the century. Temperatures are projected to rise 5.3 to 8.8 degrees Fahrenheit by the 2080s.
Sea level rise, however, may pose an even greater challenge for coastal New York. Average sea levels have risen about 1.2 inches per decade in the city since 1900, or about 1.1 feet overall, according to the new report. This is almost twice the average global rate of 0.5 to 0.7 inches per decade.
This trend is expected to accelerate in the coming decades as greenhouse gas emissions generated by human activity continue to trap more of the sun's heat, warming and expanding the oceans and melting land-based glaciers and ice caps, among other contributions.
“The task at hand is daunting -- and that is why we’re making an unprecedented commitment, with a sweeping plan to reduce emissions 80 percent by 2050, and a comprehensive, multi-layered resiliency plan that is already making neighborhoods safer," New York City Mayor Bill de Blasio said in a press statement.
The report's authors project sea levels around New York City will rise 11 to 21 inches by the middle of the century, 18 to 39 inches by the 2080s, and up to 6 feet by 2100. The researchers noted that their projections are specific to New York City, but "projections based on similar methods would not differ greatly throughout the coastal corridor from Boston to Washington, D.C."
"It is virtually certain that sea level rise alone will lead to an increased frequency and intensity of coastal flooding as the century progresses," they wrote. If sea levels rise to the higher end of current projections, twice as much of New York City will lie within the 100-year flood plain in 2100, as compared to 2013.
At 6 feet of sea level rise in 2100, nearly 20 percent of New York City's 469-square-mile land area would have a 1 percent chance of flooding in any given year. A little under 11 percent of the city's area is currently included in the 100-year flood plain, according to a preliminary FEMA assessment released in December 2013.
About 400,000 New Yorkers live within the current 100-year flood plain, which is more than any other U.S. city, including New Orleans.
"Sea level rise is an extremely challenging problem that requires both greenhouse gas emissions reduction and adaptation measures to successfully protect vulnerable coastal areas," Princeton University professor Michael Oppenheimer, who contributed to the report, told The Huffington Post. "This report is a model of how technical information can support decision-making."
This map shows areas of New York City that are likely to be flood-prone in the future, as a result of sea level rise.
"The report blends cutting-edge science with presentation of the information to policy makers in a risk-based framework so they are in a position to use it to make key judgments about how to protect a city from climate change," Oppenheimer said.
Hurricane Sandy in 2012 demonstrated some of the challenges New York will face this century, particularly when it comes to adapting the city's aging infrastructure and transportation network. Flooding from Sandy knocked out power for part of Manhattan and the storm caused unprecedented flooding in the city's train and vehicular tunnels under the Hudson and East rivers.
This week's report recommends that the city consider both mitigating climate change, through reducing emissions, and adapting to it. The authors advocate a multifaceted adaptation approach that uses engineering and existing ecosystems. Experts have previously cautioned that manmade "gray" infrastructure alone cannot solve New York City's resiliency challenges.
“Adapting the city for the risks of climate change is one of the great challenges of our time,” Daniel Zarrilli, director of the mayor’s Office of Recovery and Resiliency, said in a press release.
Along with Tuesday’s report, city leaders also announced progress on efforts to make New York more sustainable and improve resiliency. Measures include design work on a flood protection system for Manhattan’s Lower East Side and investments to protect vulnerable waterfront communities, among other programs. The city has also coated over 6 million square feet of roofs with reflective paint to cool buildings and combat urban heat island effect.
“This report from the New York City Panel on Climate Change advances the science of climate resiliency and highlights the risks the City faces from multiple climate impacts, making it clear that we must continue to build a stronger, more resilient New York,” Zarrilli said. “That’s why we are moving forward on projects across the city in partnership with a wide array of community partners and other stakeholders.”
Embarrass, MN - I couldn't have made this up
Thermometers malfunctioned in Minnesota:
MINNEAPOLIS (WCCO/AP) —* Some of the coldest air of the season has settled into Minnesota.
The bottom dropped out of readings in the northern region of the state Thursday. The community of Embarrass reported a temperature of 41 below zero. That’s without the wind chill factor. Forecasters say that’s the lowest recorded temperature in northern Minnesota this winter.
Florida in the 30 degree range? What to do?
The nation is still in the midst*a winter grip that seems to be getting tighter instead of looser with many parts of the country experiencing life-threatening cold.
Wind chill advisories were issued Wednesday from*Chicago and Detroit and extending as far east as Baltimore. In some areas, the brutally cold winds will bring temperatures of minus 9 with wind chills as low as*minus 25 degrees.
Forecasters in Raleigh, North Carolina,*issued warnings*that Thursday will bring “life-threatening” cold. Authorities warn that “freezing winds that could cause frostbite and put lives at risk” will descend on the area.
Even Florida is set to have temperatures in the*low 30s.
All time record lows smashed
Flint, Mich., has tied its all-time record low for any month*when the temperature dropped to a brutal minus 25 degrees on Friday morning. The last time it was so cold in Flint was on Jan. 18, 1976.
Cleveland broke its all-time record low for the month of February when the thermometer bottomed out at 17 degrees below zero on Friday morning. The new record surpassed the previous by one degree, set more than a century ago on Feb. 10, 1899.
Many record lows for the date have been set in major cities along the Eastern Seaboard, including New York, Pittsburgh, Baltimore, Washington, D.C., Atlanta and Miami.
In Washington, a temperature of 5 degrees Friday morning was enough to smash a 120-year-old record for this date. That temperature, as measured at Reagan National Airport, broke the mark of 8 degrees that entered the record books on this date in 1896. D.C.’s record low of 5 degrees also surpassed last winter’s coldest low of 6 degrees on Jan. 7, 2014.

DC set for all time record low
Another arctic blast arrived last night and this morning gusty breezes will make it feel like it’s well below zero. This afternoon features partly sunny skies with a few flurries with feel like temperatures in the single digits all day. Speaking of single digits, tonight that is likely for downtown D.C. with some of our suburbs slipping below zero making it the coldest air we’ve seen in over 20 years. Factor in the breeze and it will be brutal
I'd keep going but my battery is dying, probably due to the cold, gotta recharge.
