Klimareporter° Weltweiter CO2-Ausstoß bis 2017. Potsdam-Institut für Klimafolgenforschung. Welt steuert auf mindestens drei Grad zu – selbst mit umgesetztem Klimaschutz Kaum noch Chancen fürs Zwei-Grad-Ziel. Hat die Menschheit versagt?
Die Chance, die Erderwärmung bis 2100 auf zwei Grad oder weniger zu begrenzen, liegt nur noch bei rund fünf Prozent, wie Klimaforscher ermittelt haben. Selbst wenn man sofort alle CO2-Emissionen weltweit stoppen würde – was absolut unrealistisch wäre, steigen die Temperaturen bis 2100 in jedem Falle um 1,3 Grad. Das Klimaschutzziel von Paris ist daher nur noch mit drastischen, schnellen Maßnahmen zu erreichen, so die Forscher im Fachmagazin „Nature Climate Change“. Die Aussichten sind nicht rosig: Geht der Klimawandel so weiter, drohen in vielen Teilen der Erde Hitze, Dürren, sintflutartige Regenfälle und überflutete Küstengebiete. Zwei Milliarden Menschen könnten dadurch zu Klimaflüchtlingen werden, so die düstere Prognose.
Extrapolation aktueller Trends Doch wie realistisch ist dieses Zwei-Grad-Ziel? 1912 Newspaper Article Anticipates Anthropogenic Global Warming. Claim: A 14 August 1912 article from a New Zealand newspaper contains a brief story about how burning coal might produce future warming by adding carbon dioxide to the atmosphere.
Origin:On 11 October 2016, the Facebook page “Sustainable Business Network NZ” posted a photograph of a clipping from the 14 August 1912 edition of the Rodney and Otamatea Times, Waitemata and Kaipara Gazette that included a brief item headlined “Coal Consumption Affecting Climate”: The furnaces of the world are now burning about 2,000,000,000 tons of coal a year. When this is burned, uniting with oxygen, it adds about 7,000,000,000 tons of carbon dioxide to the atmosphere yearly. This tends to make the air a more effective blanket for the earth and to raise its temperature. The effect may be considerable in a few centuries. Oil Investors at Brink of Losing Trillions of Dollars in Assets. Gore: It's That Road Runner Moment. Climate: Now or Never A major threat to fossil fuel companies has suddenly moved from the fringe to center stage with a dramatic announcement by Germany’s biggest power company and an intriguing letter from the Bank of England.
A growing minority of investors and regulators are probing the possibility that untapped deposits of oil, gas and coal -- valued at trillions of dollars globally -- could become stranded assets as governments adopt stricter climate change policies. Steve Schneider's Global Warming Warning 30 years ago. The 1847 lecture that predicted human-induced climate change. The increasing value of timber and fuel ought to teach us that trees are no longer what they were in our fathers' time, an incumbrance.
We have undoubtedly already a larger proportion of cleared land in Vermont than would be required, with proper culture, for the support of a much greater population than we now possess, and every additional acre both lessens our means for thorough husbandry, by disproportionately extending its area, and deprives succeeding generations of what, though comparatively worthless to us, would be of great value to them.The functions of the forest, besides supplying timber and fuel, are very various.
Evidence. The Earth's climate has changed throughout history.
Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives. Scientific evidence for warming of the climate system is unequivocal.

Individual and political action on climate change. Individual and political action on climate change can take many forms, most of which have the ultimate goal of limiting and/or reducing the concentration of greenhouse gases in the atmosphere, toward avoiding dangerous climate change.
Political action Political action can change laws and regulations that relate to climate change, such as tax incentives, greenhouse gas emissions limits or establishing a regulatory framework within which carbon trading markets can operate. The Compensators - Verschmutzungsrechte kaufen und löschen. Victory at Hand for the Climate Movement? There are signs the climate movement could be on the verge of a remarkable and surprising victory.
If we read the current context correctly, and if the movement can adjust its strategy to capture the opportunity presented, it could usher in the fastest and most dramatic economic transformation in history. This would include the removal of the oil, coal and gas industries from the economy in just a few decades and their replacement with new industries and, for the most part, entirely new companies. It would be the greatest transfer of wealth and power between industries and countries the world has ever seen.
To understand this incredible potential we first have to step back and understand the unique structure of this social change movement, which may rank among the most influential in history. It is simplistic to characterise it as an alliance of grass roots organisations and activists pitched against a rich and well connected adversary. To summarise: Is that it? Dan Miller: Boom or Bust?

Exclusive: Climate Hustle’s Marc Morano Turns Down $20k Global Warming Bets From Bill Nye The Science Guy. One of America’s most outspoken deniers of the link between fossil fuel burning and global warming has refused $20,000 in bets that the planet will keep getting hotter. Offering the two bets to Marc Morano, of the conservative think tank the Committee for a Constructive Tomorrow (CFACT), is popular television science presenter Bill Nye, “the science guy”. Nye said he was willing to bet Morano that 2016 would be one of the ten hottest years on record. He also offered a bet the current decade would be the hottest on record. Morano turned down both bets, telling DeSmog it was “silly” to take a bet when it was “obvious” the official records would show more global warming.
CO₂ zählen ist kein Klimaschutz. Sonntag, 08. Two degrees: Will we avoid dangerous climate change? 09 Dec 2014, 11:30Simon Evans Limiting warming to no more than two degrees has become the internationally accepted target for climate policy, as we saw in the first blog of our series of pieces looking at the two degrees limit. Scientists think the risks of climate change increase as temperatures rise. Two degrees isn't a 'safe' level of climate change, but nor is it a red line with only chaos beyond, as we'll see in part three. Two degrees? Sounds nice. The reality will be rather different. If we continue to emit ever-greater quantities of CO2 and other greenhouse gases into the atmosphere, then average global temperatures will rise by 2°C over the next three decades compared to pre-industrial times.
Most scientists agree that anything higher is dangerous, though many argue that even this is too much. As the battles to reach an agreement in Paris begin, and with so much at stake, it is perhaps curious that few people really understand what a 2°C rise in average temperatures will mean. Jeremy Jackson: Sea Level Rise is Dangerous. Which fossil fuel companies are most responsible for climate change? – interactive. Turn autoplay off Edition: <span><a href=" Zementindustrie verursacht sechs Prozent. About. CO2 emissions from the cement industry constitute 5% (or 1.9 Gt annually) of global anthropogenic CO2 emissions. In 2013, approximately 20% of global CO2 emissions from cement production originated from Europe (EU28). Given the ambitious energy and climate targets that the EU has proposed and agreed on (40% emissions reduction by 2030, 80-95% emissions reduction by 2050), CO2 emissions from energy-intensive industries will need to be eliminated or significantly reduced.
CO2 generation is an inherent part of the cement production process, due to the calcination of the most important raw material, limestone (CaCO3 converted to CaO and CO2): about 60 % of the CO2 emissions from cement production are due to this conversion, whereas 40% come from the burning of fuels (which are to a large extent fossil) to provide heat for the clinker production. There are currently no feasible methods to produce clinker and thus cement without releasing CO2 from CaCO3. Movie Review: There’s a Vast Cowspiracy about Climate Change.
