Three foreign countries may be changing their historical weather data to show warming trends, according to a scientist in the field.
Dr. H. Sterling Burnett of the Heartland Institute claims
in a story that Australia, Paraguay, and Switzerland have altered their data in an effort to prove global warming is real.
"Switzerland joins a growing list of countries whose temperature measurements have been adjusted to show greater warming than actually measured by its temperature instruments," Burnett writes. "In previous editions of Climate Change Weekly, I reported weather bureaus in Australia and Paraguay were caught adjusting datasets from their temperature gauges. After the adjustment, the temperatures reported were consistently higher than those actually recorded."
Citing a report from Swiss Science journalist Markus Schär, Burnett writes that Switzerland altered its weather data and now it shows a "doubling of the temperature trend."
"For example, in Sion and Zurich, [the Swiss Meteorological Service] adjustments resulted in a doubling of the temperature trend," Burnett writes. "Schär notes there has been an 18-year-pause in rising temperatures, even with data-tampering. As a result, Schär calls the adjustments a 'propaganda trick, and not a valid trend.'"
In March, it was reported
that U.S. government scientists often change weather data — a practice that is neither new nor a secret. Scientists say the data is changed to correct for inaccuracies in testing. Critics say it is a way to show a warming trend, which it has done.
"[The National Climatic Data Center, or NCDC] pulls every trick in the book to turn the U.S. cooling trend into warming. The raw data shows cooling since the 1920s," a science blogger said.
"NCDC does a hockey stick of adjustments to reverse the trend. This includes cooling the past for 'time of observation bias' in filling missing rural data with urban temperatures, and doing almost nothing to compensate for urban heat island effects."
Global warming skeptics say it is a man-made scam, but defenders of the phenomenon point to evidence in weather data — which is apparently being changed in countries across the world.
Bill Nye, who hosted a popular children's show in the 1990s, told Rutgers University graduates over the weekend global warming is real.
"So, hey deniers — cut it out, and let's get to work," Nye said.
