Climate Change Weekly #66

NASA scientists report that a strong and persistent Arctic storm broke up sea ice and pushed much of it out of the Arctic Ocean in August, causing a reduction in Arctic sea ice to its lowest extent since at least 1979. The report contradicts alarmists’ assertions that this September’s unusually low amount of Arctic sea ice proves the existence of a global warming crisis.

Emphasizing the August storm’s severe impact on ice extent, NASA scientists said the storm “wreaked havoc” on Arctic sea ice.

Arctic sea ice has gradually receded since NASA satellite instruments first began measuring the polar ice caps in 1979. However, the 1979 baseline marked the end of a 30-year global cooling phase that likely resulted in more extensive polar sea ice than any time since at least the early twentieth century. Gradually warming temperatures will likely cause gradually receding Arctic sea ice, but alarmists have yet to show the gradual retreat is beyond historical parameters or is cause for serious concern.

BORENSTEIN ATTEMPTS TO HIDE ALARMISTS’ FAILED ANTARCTIC PREDICTIONS

Responding to embarrassing data showing long-term growth in Antarctic polar ice and a series of new records set by Antarctic sea ice this year, Associated Press reporter and prominent global warming alarmist Seth Borenstein is attempting to convince people that alarmists always predicted expanding Antarctic polar ice. Science writer Joanne Nova delivers the truth, debunking Borenstein’s claim and documenting many instances in which alarmists claimed global warming is or should soon cause receding Antarctic polar ice.

TRENBERTH REPORTS LESS IPCC CONSENSUS ON GLOBAL WARMING

It is becoming harder to pull together a scientific consensus among United Nations Intergovernmental Panel on Climate Change (IPCC) participants, National Center for Atmospheric Research scientist Kevin Trenberth admits in Australia’s Brisbane Times. Trenberth, a prominent global warming alarmist who was a lead author for the past two IPCC reports, said, “There are more people, it’s more diffuse, it’s harder to gain a consensus – quite frankly I find the whole process very depressing.”

WATTS DEBUNKS USA TODAY EXTREME WEATHER CLAIMS

Meteorologist Anthony Watts delivered a compelling rebuttal to a USA Today article claiming a steep rise in weather-related catastrophes during the past few decades. Watts showed a long-term decline in tornado activity, hurricane activity, heat waves, and drought.

SOUND SCIENCE DAMPENS CORAL REEF SCARE

A rash of recent media stories claiming a dramatic decline in the Great Barrier Reef are based on faulty science, coral reef scientist Walter Starck reports. For example, a recent study claiming a 50 percent decline in the Great Barrier Reef focused on two sections of the reef that were recently struck by major hurricanes, Starck notes. Those sections are not indicative of the reef as a whole.

HUDSON VALLEY EVIDENCE CONFIRMS MEDIEVAL WARM PERIOD

Scientists studying the Hudson River estuary in New York report evidence of a prolonged period of unusual warmth approximately 1,000 years ago, providing more evidence the Medieval Warm Period was global in extent. The scientists found evidence of Carya trees, which thrive in warm temperatures, in the Hudson River estuary during the Medieval Warm Period. This discovery “supports an increase in temperature,” the scientists report.
