The National Oceanic and Atmospheric Administration’s reliance on poorly-sited weather stations to calculate surface temperatures is inflating the warming trend of the U.S. and maybe even the rest of the world, according to a landmark study looking at three decades of data.
“The majority of weather stations used by NOAA to detect climate change temperature signal have been compromised by encroachment of artificial surfaces like concrete, asphalt, and heat sources like air conditioner exhausts,” Anthony Watts, a seasoned meteorologist and lead author of the study, said in a statement Thursday.
No “major” hurricane–defined as a Category 3 or above–has made landfall on the continental United States since 2005, according to records compiled by the National Oceanic and Atmospheric Administration’s (NOAA) Hurricane Research Division.
That is the longest stretch of time the United States has gone without a Category 3 or above hurricane striking somewhere on the mainland of the country, according to NOAA hurricane records going back to 1851.
Last month, we are told, the world enjoyed “its hottest March since records began in 1880”. This year, according to “US government scientists”, already bids to outrank 2014 as “the hottest ever”. The figures from the US National Oceanic and Atmospheric Administration (NOAA) were based, like all the other three official surface temperature records on which the world’s scientists and politicians rely, on data compiled from a network of weather stations by NOAA’s Global Historical Climate Network (GHCN).
Climate experts have confirmed last year was globally the hottest on record.
Global temperatures were 0.69C (1.24F) above 20th century averages, making 2014 the warmest year in records dating back to 1880, the US National Oceanic and Atmospheric Administration (NOAA) said.
Hackers from China breached the federal weather network recently, forcing cybersecurity teams to seal off data vital to disaster planning, aviation, shipping and scores of other crucial uses, officials said.
The intrusion occurred in late September but officials gave no indication that they had a problem until Oct. 20, said three people familiar with the hack and the subsequent reaction by the National Oceanic and Atmospheric Administration, which includes the National Weather Service. Even then, NOAA did not say its systems were compromised.
