Alarming New Study Predicts Dangerous Sea Level Rise to Occur in Decades, Not Centuries

A new scientific study, released to the media Tuesday by the European Geoscience Union’s Journal of Atmospheric and Physics, has major media sources reporting “alarming” study predictions of sea level rise and extreme weather from global warming, “much faster” than the rate of rise predicted in the most recent report by IPCC scientists. The world’s governments are being urged to “speed up the transition to carbon-free energy.” (Slate, 3/22/16)

Last year was the hottest on record. This January was the hottest on record. This February was the hottest on record — when the northern hemisphere breached 2 degrees of average warming for the first time in human history. “Our planet’s temperature just reached a terrifying milestone.” (Slate, 3/12/16)

The study uses climate simulations, paleoclimate data and modern observations to infer that continued high fossil fuel emissions will cause a slowdown and eventually shutdown the Atlantic Meridional Overturning Circulation and the Southern Meridional Oceanic Circulation, resulting in an increase in powerful storms and nonlinear sea level rise, rising up to several meters in 50–150 years.

The meridional overturning circulation is a system of surface and deep currents encompassing all ocean basins. It transports large amounts of water, heat, salt, carbon, nutrients and other substances around the globe, and connects the surface ocean and atmosphere with the huge reservoir of the deep sea. The circulation of ocean water has been found to play a central role in climate and climate variability. Historically, the focus of research has been on the North Atlantic Basin, a primary site where water sinks from the surface to depth, triggered by loss of heat, and therefore buoyancy, to the atmosphere. A key part of the overturning puzzle, however, is the return path from the interior ocean to the surface through upwelling in the Southern Ocean. This return path is largely driven by winds. It has become clear over the past few years that the importance of Southern Ocean upwelling for our understanding of climate rivals that of North Atlantic downwelling, because it controls the rate at which ocean reservoirs of heat and carbon communicate with the surface.

The authors of the new study claim that the United Nations Intergovernmental Panel on Climate Change (IPCC) “missed” reporting on these important changes in their latest IPCC report, which the 18 authors of the new study underestimates ice sheet melt and the IPCC’s models are too insensitive to accurately  account for ocean waters mixing.

In a video abstract: “Ice melt, Sea Level Rise and Superstorms”, lead author and climate scientist Dr. James Hansen states that evidence from paleoclimate data, climate modeling, and modern observations show that the maximum level of global warming that was set at the Paris Climate Summit meetings in early December 2015 of  2°C global warming to be “highly dangerous” and that “We have a climate emergency and must slash CO2 emissions ASAP or irreparable harm to the climate will be done for succeeding generations”.

I am presently a Volunteer for Habitat for Humanity, Madison, Wisconsin. I oppose all long (>500 miles) distance travel (via fossil fuel burning) for nonessential purposes and all ownership of more than one home. I am opposed to militarism in any form particularly for the purpose of monetary gain. I am a Strong believer in people everywhere having the right to speak their minds openly, without any fear of reprisal, regarding any concerns; especially against those in authority who are not acting for the public good?in a timely fashion and in all countries of the world not just the U S.. My identical twin, Pat, died in June 2009. He was fired from his job with the National Weather Service despite having a long and successful career as a flood forecaster with the Kansas City National Weather Service. He took a new position in the Midwest Regional Office in Minneapolis. Unfortunately, Pat’s work for the NWS went sour after he began to see the evidence for concern about rising global temperatures shortly after relocating to Minneapolis, and how they appeared to effect of flooding on the Red River that flows out of Canada before entering the U.S. in North Dakota. . Pat and I conversed on a regular basis with other scientists on the Yahoo Group named “Climate Concern “ and by personal email. The NWS denied his recommendation to give his public presentation o n his research at the “Minneapolis Mall of America” in February 2000, which deeply affected h,im. I will h He strongly believed the information ought be shared with the public to which I concurred. That was the beginning of the vendetta against my brother, Patrick J. Neuman, for speaking strongly of the obligations the federal government was responsible for accurately informing the citizenry. A way great similar response to my raising the issue of too many greenhouse gases being emitted by drivers of vehicles on Wisconsin highway system, my immediate supervisors directed: “that neither global warming, climate change nor the long term impacts upon the natural resources of Wisconsin from expansion of the state highway system were to be any part of my job requirements, and that I must not communicate, nor in a memorandum to all the bureau, shall any person who works in the same bureau I do communicate with me, neither verbally on the phone, by email.
