Wait Antarctica's Ice Sheet Expansion is Due to an error that is 23 Years Old?

This is one of the reasons why people have trouble trusting climate science.

But a new study by scientists from NASA and Scripps Institution of Oceanography found that a processing error originating from a recalibration made to satellite readings made in 1991 resulted in an artificial jump in Antarctic sea ice extent that was not apparent until the data was reprocessed in 2007.

This means that Antarctic sea ice coverage may have not been accelerating as fast as was previously thought, according to the study’s authors.

“Here, we show that much of the increase in the reported trend occurred due to the previously undocumented effect of a change in the way the satellite sea ice observations are processed for the widely used Bootstrap algorithm data set, rather than a physical increase in the rate of ice advance,” writes lead author Ian Eisenman, a climate researcher at Scripps Institute of Oceanography, and others.

So this error is 23 years old and was only discovered after this algorithm was used for 18 years? In other words the Antarctic sea ice calculation has been wrong for two decades? This is case-in-point why people have such trouble believing climate science. This begs the question what other decades old errors are in the models that we are supposed to base tens-of-billions of dollars of spending on? Climate science so so complicated that these kind of errors really raise a bunch of doubt on the extent of climate change.
