Professor Armstrong hopes that this paper will lead Senator Boxer to reconsider the confidence that she has placed in the USGS administrative reports that predicted a sharp decline in the population of polar bears. There are no scientific forecasts of long-term global temperature and we therefore do not know whether temperatures will increase or decrease. Even the IPCC and its cadre of presumptive Nobel Peace laureates concede as much.
“Even if there were such temperature ‘forecasts,’ the relationship between Arctic ice conditions and global temperatures is not clear and neither is the relationship between ice conditions and polar bear numbers”, said Armstrong. “For example, we do know that polar bears survived much warmer times in the past. In this uncertain situation, it is unscientific to forecast dramatic changes in bear number.”
