In a June 20 interview with Spiegel Online, German climate scientist Hans von Storch said that despite predictions of a warming planet the temperature data for the past 15 years shows an increase of 0.06 or “very close to zero.”
“That hasn’t happened,” Storch said. “In fact, the increase over the last 15 years was just 0.06 degrees Celsius (0.11 degrees Fahrenheit) – a value very close to zero.”
Spiegel asked Storch why the Earth’s temperature has not risen significantly in the past 15 years despite 400 billion metric tons of carbon dioxide (CO2) being emitted into the atmosphere from human activities.
“So far, no one has been able to provide a compelling answer to why climate change seems to be taking a break,” said Storch, a professor at the Meteorological Institute of the University of Hamburg and director of the Institute for Coastal Research at the Helmholtz Research Centre in Geesthacht, Germany.
“We’re facing a puzzle,” Storch said. “Recent CO2 emissions have actually risen even more steeply than we feared.
“As a result, according to most climate models, we should have seen temperatures rise by around 0.25 degrees Celsius (0.45 degrees Fahrenheit) over the past 10 years,” he added.
“That hasn’t happened,” Storch said. “In fact, the increase over the last 15 years was just 0.06 degrees Celsius (0.11 degrees Fahrenheit) — a value very close to zero.
Storch said the United Nation’s Intergovernmental Panel on Climate Change (IPCC) would have to address these facts in its next climate assessment report due out late next year.
