    1. Das kommt darauf an, womit man sie vergleicht. Pro Kilowattstunde Atomstrom fallen laut dem Weltklimarat IPCC 3,7 bis 110 Gramm CO2 an. Diese gigantische Spanne kommt unter anderem dadurch zustande, dass die Endlagerung des Atommülls noch ein ungelöstes Riesenproblem ist, was auch Ungewissheiten bei der CO2-Bilanz mit sich bringt. Das Umweltbundesamt nutzt den Mittelwert von 55 Gramm CO2 pro Kilowattstunde.

      55g CO2/kWh laut Umweltbundesamt

    1. There is no such thing as a zero- or close-to-zero emission nuclear power plant. Even existing plants emit due to the continuous mining and refining of uranium needed for the plant. Emissions from new nuclear are 78 to 178 g-CO2/kWh, not close to 0. Of this, 64 to 102 g-CO2/kWh over 100 years are emissions from the background grid while consumers wait 10 to 19 years for nuclear to come online or be refurbished, relative to 2 to 5 years for wind or solar. In addition, all nuclear plants emit 4.4 g-CO2e/kWh from the water vapor and heat they release. This contrasts with solar panels and wind turbines, which reduce heat or water vapor fluxes to the air by about 2.2 g-CO2e/kWh for a net difference from this factor alone of 6.6 g-CO2e/kWh.

    1. Manmade CO2 Does Not Cause Measurable Warming

      Actually, CO2 does cause measurable warming. The warming effect is not huge, and not worrisome, but it is not zero, and it is large enough to be measurable.

      There really is no question about the fact that the Earth's average temperature has warmed slightly, as CO2 levels have risen, over the last six decades. The magnitude of that change is debatable: different "global" composite temperature indices vary in their measured trend by approximately a factor of two. But none of them show zero trend.


      The "climate sensitivity" of the Earth's temperatures to changes in CO2 level can be estimated by careful comparison of measured temperatures to measured CO2 levels. Here's an example on my web site, showing how that can be done:


      Climate change is a highly politicized issue, so, as is the case for any politicized issue, if you want to understand it you need to seek out balanced information. If you want to learn about the SCIENCE of climate change, instead of political spin, here's a list of resources which can help:


      It has:

      ● accurate introductory climatology information

      ● in-depth science from BOTH skeptics & alarmists

      ● links to balanced debates between experts on BOTH sides

      ● information about climate impacts

      ● links to the best blogs on BOTH sides of the issue

    1. even if all travel were completely carbon-free (imagine a renewable-powered, electrified train system, combined with personal EVs and battery-powered airplanes), there’d still be another 80 percent of fossil fuel emissions billowing into the skies.

      Transport - "only" 20 % of carbon emissions.

    2. “I think the main issue is that people focus way, way too much on people’s personal footprints, and whether they fly or not, without really dealing with the structural things that really cause carbon dioxide levels to go up,” said Gavin Schmidt, a climatologist and the director of the NASA Goddard Institute for Space Studies in New York City.

      Key quote. Correct. Individual action is not enough. We need a collective change of behaviour.

    1. Svante Arrhenius in 1896. His paper, published in the Philosophical Magazine and Journal of Science, was the first to quantify the contribution of carbon dioxide to what scientists now call the "greenhouse effect."

      Beginning of research into greenhouse gasses, global warming and CO2 emissions.

      me llamo mucho la atención este documento ya que habla del equipo como tal,cosa que no había tenido en cuenta


      parece ser que ya hay una experimentación de la extracción por fluidos supercriticos, pero aquí se utiliza agua y es la extracción de polifenoles en general

    1. ‘Truly it would seem as if “Man strews the earth with ruin.”4 But this conclusion is too flattering to human vanity. Man's most permanent memorial is a rubbish-heap, and even that is doomed to be obliterated’ (Sherlock, 1922, p. 343

      CO2 atmospheric concentration used as simple indicator for many years to track great acceleration / progression in Anthropocence, this now joined by long list of other indicators, escalating at an alarming rate, population, water use/ shortage, paper consumption, global warming, increase in number and ferocity of storms .......

    2. In 1873, the Italian geologist and priest Antonio Stoppani suggested that our technologies, infrastructures, and patterns of land use had created fundamental changes in Earth’s systems, propelling us into what he called an ‘anthropozoic era’
