Robert Hunziker (a US writer) (2015): “Climate genocide… Not only that, temperature changes of only two (2C) degrees Celsius warmer than today can, and did, equate to 16 feet of water for NYC whereas only four (4C) degrees Celsius cooler than today can, and did, equate to a block of ice 1.24 miles thick surrounding NYC. Those two seemingly small numbers, 2C and 4C, are examples used in Sir David Attenborough’s film, Are We Changing Planet Earth? BBC Natural History Unit, BBC One. Attenborough’s film unequivocally answers the question its title poses: “Yes, we are”… Paleoclimatologists study ice core and sediment samples to determine with remarkable accuracy how the climate changed millions of years ago. In fact, as recently as tens-of-thousands of years ago, Greenland’s temperature shot up by 5C-6C within a couple decades, not over hundreds of years and not over thousands of years…Furthermore, only recently, scientists from Rutgers University changed the course of scientific thought. Previously, scientists thought that 55 million years ago global temperatures took 10,000 years to increase by 5C. Now, a seminal sediment study by Rutgers University scientists has proven it only took 13 years for global temperatures to increase by 5C…Climate change is most prominent where people do not see it! Consequently, there are serious, informed scientists who believe the Arctic will be ice-free during the month of September, its annual minimal, within a few years. The corollary for the climate could be horrendous, devastating, and deathly. In other words, a climate holocaust may be lurking in the shadows. Such as, Arctic sea ice loss causing massive release of methane, smothering the Northern Hemisphere and life changing forever, as the planet heats up in a “geological instant.” Along those same lines, Ira Leifer, Ph.D., Atmospheric Science at the Marine Sciences Institute, University of California, Santa Barbara, claims: “Some scientists are indicating we should make plans to adapt to a 4C hotter world. While prudent, one wonders what portion of the population could adapt to such a world. My view is that it’s just a few thousand people seeking refuge in the Arctic or Antarctica”" (see Robert Hunziker, “” Climate genocide”, Counterpunch, 6 March 2015: http://www.counterpunch.org/2015/03/06/climate-genocide/ ).
