Oldspeak: “Heat-trapping gases from human activities have upset the natural balance of our atmosphere and are a major contribution to climate change… Our climate is changing, our weather is more extreme, ice sheets and glaciers are melting and sea levels are rising.  We need to act now, otherwise we will jeopardise the future of our children, grandchildren and many future generations. Time is not on our side.-WMO Secretary-General Michel Jarraud.

“Translation: “We’re fucked. But our children and grandchildren are exponentially more fucked. ” No one in positions of power anywhere in the 1st world “advanced” nations  is interested in acting now. They’re interested in “extend and pretend”. “Delay and Pray.” They meet at ineffectual climate conferences to negotiate  incremental decades long rates of change, not the radical, revolutionary change necessary right now. There is no implementable global response to the existential threats that our current carbon-nuclear based systems are creating.  There’s no profit in it. The profit is in tar sands. Methane (a.k.a. “Natural”) gas. Coal.  Efforts are underway to expand their extraction and exploitation in previously inaccessible areas of the planet.  These systems require our destruction for its continued sustenance. We are hurtling headlong toward global ecological collapse.  So, enjoy what tolerable time we have left on this dying world, as in short order, life on earth will be come fully intolerable.  Expect the worst, because it’s coming. Sandy & Haiyan are just a primer. Our infinite growth based civilization incontrovertibly assure our destruction.” -OSJ

The amount of greenhouse gases in the atmosphere reached a record high in 2012, continuing an upward trend which is driving climate change and which will shape the future of the planet for hundreds and thousands of years, according to the United Nations World Meteorological Organization (WMO).

The agency’s annual Greenhouse Gas Bulletin shows that between 1990 and 2012, there was a 32 per cent increase in radiative forcing – the warming effect on the climate – because of carbon dioxide (CO2) and other heat-trapping long-lived gases such as methane and nitrous oxide.

Carbon dioxide, mainly from fossil fuel-related emissions, accounted for 80 per cent of this increase, WMO stated in a news release. The atmospheric increase of CO2 from 2011 to 2012 was higher than its average growth rate over the past 10 years.

What is happening in the atmosphere, said the Geneva-based WMO, is “one part of a much wider picture.” Only about half of the CO2 emitted by human activities remains in the atmosphere, with the rest being absorbed in the biosphere and in the oceans.

The latest findings “highlight yet again how heat-trapping gases from human activities have upset the natural balance of our atmosphere and are a major contribution to climate change,” said WMO Secretary-General Michel Jarraud.

He recalled that the UN-backed Intergovernmental Panel on Climate Change (IPCC) stressed in its recent Fifth Assessment Report that atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased to levels unprecedented in at least the last 800,000 years.

“As a result of this, our climate is changing, our weather is more extreme, ice sheets and glaciers are melting and sea levels are rising,” said Mr. Jarraud.

He underscored that limiting climate change will require large and sustained reductions of greenhouse gas emissions. “We need to act now, otherwise we will jeopardize the future of our children, grandchildren and many future generations,” said Mr. Jarraud. “Time is not on our side,” he added.

The Greenhouse Gas Bulletin reports on atmospheric concentrations – and not emissions – of greenhouse gases. Emissions represent what goes into the atmosphere, the agency pointed out. Concentrations represent what remains in the atmosphere after the complex system of interactions between the atmosphere, biosphere and the oceans.

At the same time, the Emissions Gap Report 2013, involving 44 scientific groups coordinated by the UN Environment Programme (UNEP), urges wide-ranging global action to close the emissions gap.

If the international community fails to take action, the report warned, the chances of remaining on the least-cost path to keeping global temperature rise below 2 degrees Celsius this century will quickly diminish and open the door to a range of challenges.

Under the UN Framework Convention on Climate Change (UNFCCC), governments have agreed to limit the global temperature rise to 2 degrees Celsius to avoid the worst impacts of climate change.

The report, which was released yesterday as leaders prepare to meet for the upcoming UN Climate Change Conference in Warsaw, finds that although pathways exist that could reach the 2-degree Celsius target with higher emissions, not narrowing the gap will exacerbate mitigation challenges after 2020.

This will mean much higher rates of global emission reductions in the medium term; greater lock-in of carbon-intensive infrastructure; greater dependence on often unproven technologies in the medium term; greater costs of mitigation in the medium and long term; and greater risks of failing to meet the 2-degree Celsius target.

“As the report highlights, delayed actions mean a higher rate of climate change in the near term and likely more near-term climate impacts, as well as the continued use of carbon-intensive and energy-intensive infrastructure,” said UNEP Executive Director Achim Steiner.

“This ‘lock-in’ would slow down the introduction of climate-friendly technologies and narrow the developmental choices that would place the global community on the path to a sustainable, green future.

“However,” he added, “the stepping stone of the 2020 target can still be achieved by strengthening current pledges and by further action, including scaling up international cooperation initiatives in areas such as energy efficiency, fossil fuel subsidy reform and renewable energy.”

 

 

Global Carbon Dioxide Levels In Atmosphere Identical To Those Last Seen In Prehistoric Pliocene Era

MAUNA LOA OBSERVATORYOldspeak: “We are creating a prehistoric climate in which human societies will face huge and potentially catastrophic risks, only by urgently reducing global emissions will we be able to avoid the full consequences of turning back the climate clock by 3 million years.” –Bob Ward, policy director at the Grantham Research Institute on Climate Change at the London School of Economics. Yep. It’s that serious. Huge and catastrophic risks to all life on this planet are upon us. Meanwhile the U.S.’s selected officials are holding congressional inquiries into what happened in Benghazi, Libya, last year. Creating an immigration reform” bill with mandates for national biometric identification databases to contain information about all adult americans buried in them. Inflating bubbles to create imaginary economic growth with computer generated fiat money. Why are we paying so much  attention to what happened in the past and what is yet to happen in the future, ignoring the clear and present dangers? Why are so many resources being devoted to manufactured scandals & crises, social control plans & billionaires stealing fake money, while infinitely fewer resources, are devoted to the preeminent problem of our time? There are plans to extract dead fossil energy from the seas under the soon to be completely melted polar ice caps, which will generate more toxic emissions and quicken climate change. All plans to slow climate change are ‘market-based’ and profit driven. We know how the corporatocracy is preparing for our dystopic future.  Private armies and gated communities, while cutting resources to the poor, sick and elderly. The mass of people and the planet are not a priority. The people need to demand immediate, coherent, decisive, sustainable and drastically different energy policy.”

By Damian Carrington @ The UK Guardian:

For the first time in human history, the concentration of climate-warming carbon dioxide in the atmosphere has passed the milestone level of 400 parts per million (ppm). The last time so much greenhouse gas was in the air was several million years ago, when the Arctic was ice-free, savannah spread across the Sahara desert and sea level was up to 40 metres higher than today.

These conditions are expected to return in time, with devastating consequences for civilisation, unless emissions of CO2 from the burning of coal, gas and oil are rapidly curtailed. But despite increasingly severe warnings from scientists and a major economic recession, global emissions have continued to soar unchecked.

“It is symbolic, a point to pause and think about where we have been and where we are going,” said Professor Ralph Keeling, who oversees the measurements on a Hawaian volcano, which were begun by his father in 1958. “It’s like turning 50: it’s a wake up to what has been building up in front of us all along.”

“The passing of this milestone is a significant reminder of the rapid rate at which – and the extent to which – we have increased the concentration of greenhouse gases in the atmosphere,” said Prof Rajendra Pachauri, chair of the Intergovernmental Panel on Climate Change, which serves as science adviser to the world’s governments. “At the beginning of industrialisation the concentration of CO2 was just 280ppm. We must hope that the world crossing this milestone will bring about awareness of the scientific reality of climate change and how human society should deal with the challenge.”

The world’s governments have agreed to keep the rise in global average temperature, which have already risen by over 1C, to 2C, the level beyond which catastrophic warming is thought to become unstoppable. But the International Energy Agency warned in 2012 that on current emissions trends the world will see 6C of warming, a level scientists warn would lead to chaos. With no slowing of emissions seen to date, there is already mounting pressure on the UN summit in Paris in 2015, which is the deadline set to settle a binding international treaty to curb emissions.

Edward Davey, the UK’s energy and climate change secretary, said: “This isn’t just a symbolic milestone, it’s yet another piece of clear scientific evidence of the effect human activity is having on our planet. I’ve made clear I will not let up on efforts to secure the legally binding deal the world needs by 2015 to avoid the worst effects of climate change.”

Two CO2 monitoring stations high on the Hawaiian volcano of Mauna Loa are run by the US National Oceanic and Atmospheric Administration and the Scripps Institution of Oceanography and provide the global benchmark measurement. Data released on Friday shows the daily average has passed 400ppm for the first time in its half century of recording. The level peaks in May each year as the CO2 released by decaying vegetation is taken up by renewed plant growth in the northern hemisphere, where the bulk of plants grow.

Analysis of fossil air trapped in ancient ice and other data indicate that this level has not been seen on Earth for 3-5 million years, a period called the Pliocene. At that time, global average temperatures were 3 or 4C higher than today’s and 8C warmer at the poles. Reef corals suffered a major extinction while forests grew up to the northern edge of the Arctic Ocean, a region which is today bare tundra.

“I think it is likely that all these ecosystem changes could recur,” said Richard Norris, a colleague of Keeling’s at Scripps. The Earth’s climate system takes time to adjust to the increased heat being trapped by high greenhouse levels and it may take hundreds of years for the great ice caps in Antarctica and Greenland to melt to the small size of the Pliocence and sea level far above many of the world’s major cities.

But the extreme speed at which CO2 in now rising – perhaps 75 times faster than in pre-industrial time – has never been seen in geological records and some effects of climate change are already being seen, with extreme heatwaves and flooding now more likely. Recent wet and cold summer weather in Europe has been linked to changes in the high level jetstream winds, in turn linked to the rapidly melting sea ice in the Arctic, which shrank to its lowest recorded level in September.

“We are creating a prehistoric climate in which human societies will face huge and potentially catastrophic risks,” said Bob Ward, policy director at the Grantham Research Institute on Climate Change at the London School of Economics. “Only by urgently reducing global emissions will we be able to avoid the full consequences of turning back the climate clock by 3 million years.”

“The 400ppm threshold is a sobering milestone and should serve as a wake up call for all of us to support clean energy technology and reduce emissions of greenhouse gases, before it’s too late for our children and grandchildren,” said Tim Lueker, a carbon cycle scientist at Scripps.

Professor Bob Watson, former IPCC chair and UK government chief scientific adviser, said: “Passing 400ppm of carbon dioxide in the atmosphere is indeed a landmark and the rate of increase is faster than ever and shows no sign of abating due to a lack of political committment to address the urgent issue of climate change – the world is now most likely committed to an increase in surface temperature of 3C-5C compared to pre-industrial times.”

The graph of the rising CO2 at Mauna Loa is known as the Keeling curve, after the late Dave Keeling, the scientist who began the measurements in March 1958. The isolated Hawaiian island is a good location for measurements as it is far from the main sources of CO2, meaning it represents a good global average.
