British coal industry flack pushes geo-engineering "ploy" to give politicians... - 0 views

  • The geo-engineering option provides the needed viable reason to do nothing about AGW now….
  • “The ‘geo-engineering’ approaches considered so far appear to be afflicted with some combination of high costs, low leverage, and a high likelihood of serious side effects.“
  • they simply omit the costs of many of the potential negative aspects of producing a stratospheric cloud to block out sunlight or cloud brightening

  • That the second author works for the American Enterprise Institute, a lobbying group that has been a leading global warming denier, is not surprising, except that now they are in favor of a solution to a problem they have claimed for years does not exist.
  • The American Meteorological Society (AMS) has just issued a policy statement on geoengineering, which urges cautious consideration, more research, and appropriate restrictions.
  • ignore the effects of ocean acidification from continued CO2 emissions
  • do not even mention several potential negative effects of SRM, including getting rid of blue skies, huge reductions in solar power from systems using direct solar radiation, or ruining terrestrial optical astronomy
  • cloud brightening would mainly cool the oceans and not affect land temperature much
  • cloud brightening over the South Atlantic would produce severe drought over the Amazon, destroying the tropical forest
  • Whose hand would be on the global thermostat? Who would trust military aircraft or a multi-national geoengineering company to have the interests of the people of the planet foremost?
  • threat to the water supply for agriculture and other human uses
  • benefits from SRM, including increased plant productivity and an enhanced CO2 sink from vegetation that grows more when subject to diffuse radiation
  • The real consensus, as expressed at the National Academy conference and in the AMS statement, is that mitigation needs to be our first and overwhelming response to global warming, and that whether geoengineering can even be considered as an emergency measure in the future should climate change become too dangerous is not now known.

'No regrets': The World Bank and climate change (Bretton Woods Project) - 0 views

  • Developing and middle income countries were angry that while the draft framework contains a range of prescriptions for developing countries, it fails to recognise that developed countries should uphold their responsibilities to take the lead in combating climate change by reducing their emissions.
  • The draft framework has little to say about existing operations, but the Bank claims to be "leading by example" by making all its offices "carbon neutral", though this will largely be achieved by the controversial practice of purchasing offsets rather than reducing emissions.

Dealing with climate change? Think like an octopus - The Daily Climate - 1 views

  • "Adaptability is how all biological organisms have dealt with the fact that they can never eliminate the risks."
  • Nature's mechanisms for dealing with that are fairly simple, he added: They're decentralized, they have redundant parts, they form highly symbiotic networks, and they iterate success.

Climate change to fuel dramatic rise in energy demand by 2050 | Verdict - 1 views

  •  
    An exhaustive global study has found that climate change is set to drive up energy demand significantly by 2050, suggesting policymakers and the energy industry need to take action now to prevent a surge in energy related costs over the next few decades.

Big business goes to Rio -- New Internationalist - 0 views

  • Harmless-sounding phrases like ‘green economy’ and ‘sustainable development’ have become grounds for bitter dispute, as different governments and business interests attempt to redefine these terms to meet their own agenda.
  • This row of well-meaning policy sandcastles have spent the past 20 years being eaten away by a rising tide of fundamentalist free-market economics, unfettered financial speculation, and consolidated corporate power.
  • any environmental and social gains from the first Rio summit look small next to the destruction wrought by a voracious corporate sector and by governments obsessed with growth in GDP before all else.
  • ...8 more annotations...
  • A shift to a genuinely sustainable society will require us to challenge these negative forces, rein in the excesses of corporations and markets, and build an entirely different economy based on wellbeing for the many rather than profits for the few.
  • Silvia Ribeiro from the campaign group ETC Mexico points out: ‘Collapsing financial markets in Northern countries mean that banks and other investors are now looking desperately for new areas of expansion and speculation. We can see these desires leaving their mark on the Rio+20 process. The “Green Economy” now under discussion would unleash a wave of risky but lucrative new technologies such as synthetic biology, nanotechnology and climate technofixes. This isn’t about finding the best environmental solutions: it’s about creating profitable new investments.’
  • we cannot afford to live in a world where ecosystems are protected if, and only if, there is more profit to be made by protecting them than by trashing them.
  • Large polluting industries, business lobby groups and financial institutions are welcomed in as well-meaning ‘stakeholders’ – like mafia bosses invited to a meeting on reducing gang violence.
  • The businesses with the most wealth and power are those that have flourished in an economy based on the unrestricted use of natural resources and the exploitation of many of the world’s people. Those with the most to lose from a shift to true sustainability are therefore those with the most power to block that change.
  • the Stockholm Environment Institute calculated that the economic value of the oceans could be reduced by up to $2 trillion per year if climate change is left unchecked
  • Tom Goldtooth, Executive Director of IEN, said: ‘Systems such as “payment for ecological services” and using forests in carbon offset markets do nothing but make Mother Earth into the World Trade Organization of nature.’
  • According to Lucia Ortiz of Friends of the Earth Brazil: ‘Trades Unions are getting very concerned about the “green economy” agenda, because it represents a deepening of neoliberal policies, and threatens to undermine the social rights already secured by past struggles. They are working in solidarity with environmentalists, indigenous peoples, farmers and women’s rights activists, calling instead for a transition to a sustainable and just society free from the exploitation of workers and of nature.’

Nasa-funded study: industrial civilisation headed for 'irreversible collapse'? | Nafeez... - 0 views

  • By investigating the human-nature dynamics of these past cases of collapse, the project identifies the most salient interrelated factors which explain civilisational decline, and which may help determine the risk of collapse today: namely, Population, Climate, Water, Agriculture, and Energy.
    • Benno Hansen
       
      NASA har lavet Collapse 2 ?
  • These factors can lead to collapse when they converge to generate two crucial social features: "the stretching of resources due to the strain placed on the ecological carrying capacity"; and "the economic stratification of society into Elites [rich] and Masses (or "Commoners") [poor]" These social phenomena have played "a central role in the character or in the process of the collapse," in all such cases over "the last five thousand years."
  • The study challenges those who argue that technology will resolve these challenges by increasing efficiency: "Technological change can raise the efficiency of resource use, but it also tends to raise both per capita resource consumption and the scale of resource extraction, so that, absent policy effects, the increases in consumption often compensate for the increased efficiency of resource use."

IRIN Middle East | Middle East | Lebanon | LEBANON: Climate change and politics threate... - 0 views

  • rising temperatures, spiralling population growth and inefficient irrigation are severely straining resources and threatening renewed economic and social breakdown.
  • Lebanon has the highest annual rainfall in the region, averaging 827mm compared to 630mm in Israel, 252mm in Syria and just 154mm in Iraq
  • Yet experts estimate that demand for water in Lebanon will have increased by more than 80 percent by 2025 as Lebanon’s population is expected to grow from four to 7.6 million. In the same period, as a result of climate change, average summer temperatures in the country are predicted to increase by 1.2 degrees centigrade.

  • Across areas of the northern Bekaa with better irrigation, many farmers have turned land over to growing water-thirsty but economically lucrative hashish plants – totalling some 16,000 acres of land
  • The valley is an economically underdeveloped area where more than 40 percent of residents are dependent on agriculture as their main source of living

North American tree deaths accelerate : Nature News - 0 views

  • Mortality increase correlates with climate change.
  • The mortality rates, which are of the order of 1%, have in many cases doubled in just a couple of decades.
  • This subtle trend correlates with climate change in the region, which has warmed by between 0.3 and 0.4 degrees Celsius every decade since the 1970s.

  • The team ruled out a number of competing explanations for the trend.
  • The actual mechanism, he speculates, could vary between different forests.

      Generalized mechanism: individual trees effectively "teleported" to foreign ecosystem.

Plant life saved Earth from an icy fate - environment - 02 July 2009 - New Scientist - 0 views

  • About 50 million years ago, Earth was a hothouse – the poles were ice free, and crocodiles lived in the Arctic. Then, the concentration of carbon dioxide in the atmosphere started dropping from around 1000-1500 parts per million (ppm), and the Earth began to cool.
  • By about 24 million years ago, the uplift of the Himalayan and Andes mountain ranges led to large-scale weathering of rocks, a process that removes massive amounts of CO2 from the atmosphere. This reduced the greenhouse effect and cooled the planet.
  • Trees play an important role in the sequestration of atmospheric CO2 in magnesium and calcium carbonate rocks.
