On climate change, it’s time to start panicking The crisis over global warming warrants an unparalleled response www.salon.com/2018/08/05/on-climate-change-its-time-to-start-panicking/For the people who shout that believers in climate change are too alarmed this headline with the word Panic puts it into realistic perspective because there are details & discussion of an appropriate response: "There will be and already is major consequences and they grow over time. It does not look good," Kevin Trenberth, a a Distinguished Senior Scientist in the Climate Analysis Section at the National Center for Atmospheric Research at the University Corporation for Atmospheric Research, told Salon by email. "The effects are always local but there are more and more of them and the consequences are major. These includes floods and drought, heat waves and wild fires." He also pointed Salon in the direction of a paper he co-authored that elaborated on how Hurricane Harvey in particular could be linked to climate change. Indeed, the California wildfires that ravaged America's most populous state last month provide a major example of the dangers of man-made climate change discussed by Trenberth. A number of scientists have come out to argue that the devastating blazes were at the very least exacerbated by climate change, according to the San Francisco Chronicle. As Jennifer Francis, a professor at Rutgers University who studies atmospheric circulation, told the newspaper regarding the searing heat weave and weaker wind patterns, "We’re seeing this mix of conditions across North America and Europe, but they’re all connected. The weather patterns are just stuck. They’re trapped." "I would place a price on carbon," Michael E. Mann, a Distinguished Professor of Atmospheric Science at Penn State, told Salon by email. "Whether this takes the form of a carbon tax (a revenue-neutral carbon tax? fee and dividend? cap-and-trade?), I leave that to the policymakers to determine as long as they accept, as the premise for policy, what the science has to say about the reality and threat of climate change. The price on carbon needs to be set such that it leads to a reduction in carbon emissions of several percent a year for the next few decades. If we do that, we can avoid a catastrophic 2C (~3.5 F) warming of the planet." He also rejected the idea promoted by many on the left that a lasting solution to global warming is impossible under a free-market capitalist economic system. "I’m unconvinced that is true," Mann explained. "In the past, market mechanisms for pricing environmental externalities have worked. We acted on acid rain and ozone depletion within a market economy framework. The real problem, in my view, isn’t the nature of our economic system, it’s the way that special interests and plutocrats have blocked the sort of common-sense market approaches to dealing with environmental problems that were once supported by democrats and republicans alike. The problem is the moral and ethical rot that now lies at the very center of the republican establishment, the lack of good faith and the total sellout to special interests and plutocrats."

We now know "Contemporary Orthodox Climatology" is 'Settled Science'. Every science academy accepts the consensus that Carbon Dioxide (CO2) from Man's burning of fossil fuels is the main driver of Climate Change. iopscience.iop.org/1748-9326/8/2/024024/articleHundreds of Peer-Reviewed Studies have confirmed the consensus that climate disruption and extreme weather events are a result of the Current Climate Change known as Anthropogenic Global Warming (AGW). www.numberwatch.co.uk/warmlist.htmAlso, 'Climate Disruption' mitigation is imperative according to an international cabal of Climate Experts. www.ipcc.ch/report/ar5/wg3/mindex.shtmlStrategic studies have established a plethora of ways to mitigate the effects of "Atmospheric Anthropogenic Carbon Dioxide Driven Catastrophic Global Climate Disruption". Below -one can read two examples of peer-reviewed papers outlining a specific strategy for Saving the Planet from AGW: One proposed solution is to plant trees: www.jswconline.org/content/67/5/128A.refsThis paper provides another solution to rising CO2 levels: it involves cutting down trees and burying them in the ground... www.cbmjournal.com/content/3/1/1In conclusion: Man's august knowledge of how the climate works is not to be questioned. To best serve the planet and preserve it for future generations it is necessary to allow the experts who have studied AGW for nearly a half a century to lead us into a new era of Saving our Planet from Carbon pollution. america.aljazeera.com/articles/2014/4/12/can-carbon-dioxideremovalsavetheplanet.html

"It has been a while since I have shared science-based articles on the implications of global warming in this group. I am surprised on how little impact the recent article in the Proceedings of the National Academy of Sciences (USA) discussed in the shared post has had on discussion here. Perhaps it is time some of the doubters in this group took the science seriously and considered its implications for the futures of your family and descendents.... Rather than leading with any of the hundreds of "news" items this article generated, my post begins with the original scientific report. Climate is a complex dynamical, non-linear and (mathematically) chaotic system that is impossible to predict in any exact way. However, we understand components of the system well enough to know that there are several positive feedback loops that have the potential for chaotic and catastrophic (also a mathematical term) behavior leading to a situation of runaway warming in the Arctic. Because chaotic systems are mathematically intractable, it is not possible calculate precise probabilities that any particular scenario will/will not happen, but given that runaway warming would probably end human civilization as we know it, the risk must be considered to be existential. The authors of the PNAS article summarize the evidence for their concerns on this matter. To them the choice is stark - continue our competition to see who can build their power the fastest by degrading our biosphere with their greenhouse gas emissions - until the we have a climate catastrophe and the biosphere collapses; or else we can learn to use our knowledge and science as stewards of the Earth System by cooperating to husband and manage our resources. To do this we must replace our governments around the world that are dominated by the willing tools of the fossil fuel special interests with people who have a genuine understanding of biological systems, complexity, and the physical sciences necessary to understand and lead moderation, mitigation and remediation actions to work towards sustainable stewardship..... Today the Proceedings of the US National Academy of Science published via early release, a Perspectives article, "Trajectories of the Earth System in the Anthropocene" www.pnas.org/content/early/2018/07/31/1810141115The authors state: "We explore the risk that self-reinforcing feedbacks could push the Earth System toward a planetary threshold that, if crossed, could prevent stabilization of the climate at intermediate temperature rises and cause continued warming on a “Hothouse Earth” pathway even as human emissions are reduced. Crossing the threshold would lead to a much higher global average temperature than any interglacial in the past 1.2 million years and to sea levels significantly higher than at any time in the Holocene. We examine the evidence that such a threshold might exist and where it might be. If the threshold is crossed, the resulting trajectory would likely cause serious disruptions to ecosystems, society, and economies. Collective human action is required to steer the Earth System away from a potential threshold and stabilize it in a habitable interglacial-like state. Such action entails stewardship of the entire Earth System—biosphere, climate, and societies—and could include decarbonization of the global economy, enhancement of biosphere carbon sinks, behavioral changes, technological innovations, new governance arrangements, and transformed social values. ... Our systems approach, focusing on feedbacks, tipping points, and nonlinear dynamics, has addressed the four questions posed in the Introduction. Our analysis suggests that the Earth System may be approaching a planetary threshold that could lock in a continuing rapid pathway toward much hotter conditions—Hothouse Earth. This pathway would be propelled by strong, intrinsic, biogeophysical feedbacks difficult to influence by human actions, a pathway that could not be reversed, steered, or substantially slowed. Where such a threshold might be is uncertain, but it could be only decades ahead at a temperature rise of ∼2.0 °C above preindustrial, and thus, it could be within the range of the Paris Accord temperature targets. The impacts of a Hothouse Earth pathway on human societies would likely be massive, sometimes abrupt, and undoubtedly disruptive." Note that this approach is not "doomist", but rather makes a realistic analysis of existential risks to humanity inherent in the behavior of the chaotically complex and potentially catastrophic non-linear dynamics of the Earth's climate system. 'chaos' and 'catastrophe' as used here are technical terms of chaos theory en.wikipedia.org/wiki/Chaos_theoryen.wikipedia.org/wiki/Catastrophe_theoryWhere Earth's climate system is concerned, we can see and understand the underlying physics of major non-linearities, but because of their extreme sensitivities to other variable, models are of little use in exact prediction - the best we can hope for is that a large array of models may give us a statistical guess as to the likelihood of particular 'catastrophes'."

“Climate change is now reaching the end-game, where very soon humanity must choose between taking unprecedented action, or accepting that it has been left too late and bear the consequences.” Those are the challenging words from Prof. Hans Joachim Schellnhuber, for twenty years the head of the Potsdam Institute for Climate Impact Research, and a senior advisor to Pope Francis, German Chancellor Angela Merkel and the European Union. In the foreword to a new report, Schellnhuber says the issue now "is the very survival of our civilisation, where conventional means of analysis may become useless”. www.climatecodered.org/2018/08/take-unprecedented-action-or-bear.html

"The planet is transitioning under our onslaught to a new era called the Anthropocene. This era is the product of violent conquest, warfare, slavery, genocide and the Industrial Revolution, which began about 200 years ago, and saw humans start to burn a hundred million years of sunlight stored in the form of coal and petroleum. The numbers of humans climbed to over 7 billion. Air, water, ice and rock, which are interdependent, changed. Temperatures climbed. The Anthropocene, for humans and most other species, will most likely conclude with extinction or a massive die-off, as well as climate conditions that will preclude most known life forms. We engineered our march toward collective suicide although global warming was first identified in 1896 by the Swedish scientist Svante Arrhenius." www.truthdig.com/articles/saying-goodbye-to-planet-earth/
