  • 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.

  • "if geo-engineering studies focus too heavily on warming, critical risks associated with such possible "cures" will not be evaluated appropriately"
  • climate change is about much more than changes in temperature. So using temperature alone to monitor the effects of geo-engineering could be dangerous.
  • current climate models tend to underestimate the effects on precipitation of both greenhouse gases and of volcanic eruptions
  • ...2 more annotations...
  • The article warns that geo-engineering of this type, combined with the effects of global warming could produce reductions in regional rainfall that could rival those of past major droughts, leading to winners and losers among the human population and possible conflicts over water.

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.

    the first site which established the idea of be good people all over the world. This site is made to ask as many people as possible to make such a commitment to be good people by showing their profile. The main difference compare to the other "social-purposed sites", is that this site is more likely to push the people to be "good people" with the better consequence effects in their real life - not only online.\nWe hope by joining this site, people are expected to postpone their 'evil side' at least 5min, an hour, a day, even more as long as they can. So, if you think you're good enough, prove it here.

solar power drip irrigation third world benefits efficiency

shared by Skeptical Debunker on 03 Mar 10 - Cached
  • Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that: "solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies" Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits. "Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems" The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported: "The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season. Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."

    Several weeks ago, a group of researchers published an article in the Proceedings of the National Academy of Sciences documenting how relatively low-powered solar systems offer the potential to increase food supplies in impoverished arid regions while reducing demands for fertilizers and other costly (in fiscal and other terms) additives.

  • "A large part of the relevant legal literature suggests that the main polluting nations can be held responsible under international law for the harmful effects of their greenhouse-gas emissions," says the paper's author, lawyer Christoph Schwarte.
  • "Developing country governments are understandably reluctant to challenge any of the big donor nations in an international court or tribunal. But this may change once the impacts of climate change become even more visible and an adequate agreement remains wanting."
  • FIELD is a group of public international lawyers based in London working towards a fair, effective and accessible system of international law that protects the global environment and promotes sustainable development.

    HBO's latest offering 'Chernobyl'has grabbed a lot of attention in the last few days since it was released. This mini-series, co-starring Jared Harris, Emily Watson and StellanSkarsgard, is a very grave picturization of one of the worst human disasters in modern history. Written by Craig Mazin (of "The Hangover" Parts II and III fame) and directed by Johan Renck, this five-episode series brings back to life the tragic event of 1986 in erstwhile USSR and does not shy away from showing the horrors committed during that time. It gives the audience a glimpse of the events before, during and after the nuclear explosion, ill effects of which can be seen in Europe till date.

  • 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.

  • 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."
