Evidence of Acceleration of Anthropogenic Climate Disruption on All Fronts

This month's dispatch comes on the heels of the Intergovernmental Panel on Climate Change's (IPCC) recent report, and the news is not good.
"No one on this planet will be untouched by climate change," IPCC Chair Rajendra Pachauri announced. The report warned that climate impacts are already "severe, pervasive, and irreversible."
The IPCC report was one of many released in recent weeks, and all of them bring dire predictions of what is coming. The American Association for the Advancement of Science (AAAS) issued a report warning that "the rate of climate change now may be as fast as any extended warming period over the past 65 million years, and it is projected to accelerate in the coming decades." The report went on to warn of the risk "of abrupt, unpredictable, and potentially irreversible changes in the Earth's climate system with massively disruptive impacts," including the possible "large scale collapse of the Antarctic and Greenland ice sheets, collapse of part of the Gulf Stream, loss of the Amazon rain forest, die-off of coral reefs, and mass extinctions."

Just prior to the release of the IPCC report, the UN's World Meteorological Organization (WMO) reported that 13 of the 14 warmest years on record had all occurred since 2000. The agency's secretary-general, Michel Jarraud, described the global trend: "Every decade has been warmer than the preceding one over the last 40 years. In other words, the decade 2001-2010 was warmer than the '90s, which in turn were warmer than the '80s, which were warmer than the '70s. All the best models were used for this study, and the conclusion is actually very interesting and of concern. The conclusion is that these heat waves, it is not possible to reproduce these heat waves in the models if you don't take into account human influence." Jarraud also noted greenhouse gases are now at a record high, which guarantees the Earth's atmosphere and oceans will continue to warm for centuries to come. Arctic sea ice in 2013 did not reach the record lows seen in 2012 for minimum extent in the summer, but nevertheless reached its sixth lowest extent on record. The WMO noted all seven of the lowest Arctic sea-ice extents took place in the past seven years, starting with 2007, which scientists were "stunned" by at the time.
NASA released the results of a study showing that long-term planetary warming is continuing along the higher end of many projections. "All the evidence now agrees that future warming is likely to be towards the high end of our estimates, so it's more clear than ever that we need large, rapid emissions reductions to avoid the worst damages from climate change," lead author and NASA climatologist Drew Shindell said. If he sounds alarmist, it's because he is, and with good reason. The NASA study shows a global increase in temperatures of nine degrees by the end of the century.
This is consistent with a January Nature study on climate sensitivity, which found we are headed toward a "most-likely warming of roughly 5C (9 F) above current temperatures, which is 6C (11 F) above preindustrial" temperatures by 2100. Bear in mind that humans have never lived on a planet at temperatures 3.5C above our preindustrial baseline.
Hence, as contemporary studies continue to provide ever-higher temperature projections, they are beginning to approach higher estimates from previous studies. A 2011 paper authored by Jeffrey Kiehl from the National Center for Atmospheric Research and published in the journal Science "found that carbon dioxide may have at least twice the effect on global temperatures than currently projected by computer models of global climate." Contrary to the Intergovernmental Panel on Climate Change's (IPCC) worst-case scenario of a 6C rise by 2100, which itself would result in a virtually uninhabitable planet, Kiehl's paper distressingly concludes that, at current emission rates, we may actually see an unimaginable 16C rise by the end of the century.
"The last time it was 6C there were snakes the size of yellow school buses in the Amazon," Guy McPherson, professor emeritus of evolutionary biology, natural resources, and ecology at the University of Arizona, told Truthout. McPherson, a climate change expert of 25 years, maintains the blog Nature Bats Last. "The largest mammal was the size of a shrew," he said. "And the rise in temperature occurred over thousands of years, not decades. I doubt mammals survive - and certainly not large-bodied mammals - at 6C."
Dr McPherson went on to explain further what the planet would look like as temperatures increase.
"Rapid rise to 4C eliminates all or nearly all plankton in the ocean, along with a majority of land plants," he said. "The latter cannot keep up with rapid change. The former will be acidified out of existence. At 16C, your guess is as good as mine. But humans will not be involved."
Bear in mind that the "current" emission rates in Kiehl's study were significantly lower than those of today, as they were from more than three years ago. Emission rates have grown in each succeeding year.
Evidence is mounting that we are in the midst of a great extinction of species. An "ecocide" is occurring, as the human race is in the process of destroying life on the planet. This sobering thought becomes clearer now as we take our monthly tour of significant global pollution and anthropogenic climate disruption (ACD) related events.
Ongoing drought and other ACD-related impacts have caused the Amargosa vole, one of the rarest mammals in North America, to become an endangered species. This saddening occurrence shouldn't come as a big surprise, given that chronic drought and shifting weather patterns are causing things like a wall of dust 1,000 feet tall and 200 miles wide to roar across parts of West Texas and New Mexico.
Evidencing warnings from the IPCC report about ACD's dramatic impact on wide-scale food production, the president of the World Bank warned that battles over water and food will erupt within the next five to ten years. As if on cue, hungry monkeys in northern India have begun raiding farms as their forest habitats shrink.
Meanwhile, on the coastal areas of Alaska, melting permafrost and stronger storms are combining to erode coastline and cause greater numbers of villages to begin contemplating evacuation.
