The 1978 Paper That Predicted Our Nearing “Disaster”
If the greenhouse warming effect of the resultant increasing atmospheric CO2 is as great as the most advanced current models suggest, a critical level of warmth will have been passed in high southern latitudes 50 years from now, and deglaciation of West Antarctica will be imminent or in progress. Deglaciation would probably be rapid once it had started, and when complete would have led to a rise in sea level of about 5m along most coasts.

A trillion-ton iceberg totaling 2,240 square miles, or 12% of the Antarctic peninsula, and 40 trillion cubic feet of ice — a volume twice that of Lake Erie — today broke free from the Larsen C ice shelf in Antarctica. Following the collapse of the Larsen A ice shelf in 1995 and the Larsen B ice shelf in 2002, today’s calving further weakens the entire continental glacier and sets in motion what scientist believe is the first stage of total glacial collapse.

California’s New Family Of Wolves: The Lassen Pack
California Department of Fish and Wildlife (CDFW) biologists have captured and fitted a tracking collar to a female gray wolf in Lassen County, and confirmed that the wolf and her mate have produced at least three pups this year.
During summer and fall 2016, remote trail cameras captured images of two wolves traveling together in Lassen County. There was no evidence they had produced pups at that time. While the female’s origins remain unknown, genetic samples obtained from scat indicated the male wolf originated from Oregon’s Rogue Pack. The famous wolf OR7 is the Rogue Pack’s breeding male.
