‘Carbon sink’ detected underneath world’s deserts

WASHINGTON, D.C. – The world’s deserts may be storing some of the climate-changing carbon dioxide emitted by human activities, a new study suggests. Massive aquifers underneath deserts could hold more carbon than all the plants on land, according to the new research. Humans add carbon dioxide to the atmosphere through fossil fuel combustion and deforestation.…

CO2 Residence Times, Take Two

Guest essay by Joe Born In a recent post Christopher Monckton identified me as a proponent of the following proposition: The observed decay of bomb-generated atmospheric-carbon-14 concentration does not tell us how fast elevated atmospheric carbon-dioxide levels would subside if we discontinued the elevated emissions that are causing them. He was entirely justified in doing…

Is the Bern Model Non-Physical?

Guest essay by Joe Born Is the Bern Model non-physical? Maybe, but not because it requires the atmosphere to partition its carbon content non-physically. A Bern Model for the response of atmospheric carbon dioxide concentration to anthropogenic emissions is arrived at by adopting the values of , (and maybe ) that make the best fit…

Is Greenpeace facing its Warsawgrad?

Guest opinion by Fred F. Mueller In large-scale wars, there are sometimes prolonged periods of fierce clashes with neither side being able to place the decisive blow that will ultimately tilt the balance in its favor. Then all of a sudden, certain events occur that mark the decisive turning point where one side definitely loses…

On CO2 residence times: The chicken or the egg?

While some model based claims say that CO2 residence times may be thousands of years, a global experiment in measurable CO2 residence time seems to have already been done for us. By Christopher Monckton of Brenchley Is the ~10-year airborne half-life of 14CO2 demonstrated by the bomb-test curve (Fig. 1, and see Professor Gösta Pettersson’s…

Deserts ‘greening’ from rising CO2

From CSIRO and “increased CO2 has benefits” department:  Increased levels of carbon dioxide (CO2) have helped boost green foliage across the world’s arid regions over the past 30 years through a process called CO2 fertilisation, according to CSIRO research. In findings based on satellite observations, CSIRO, in collaboration with the Australian National University (ANU), found…

‘plug-and-play’ CO2 Scrubbers

From MIT, while “plug-and-play” is cited, it’s just a paper. Getting the carbon out of emissions Proposed method could be more efficient than previous systems and easier to retrofit in existing power plants. CAMBRIDGE, Mass. — Many researchers around the world are seeking ways to “scrub” carbon dioxide (CO2) from the emissions of fossil-fuel power…

An Engineer’s Take on Climate Change #2

Guest essay by Ronald D. Voisin High Atmospheric CO2 is Good for All Life on Earth At an atmospheric concentration of 380ppm and higher the limited long-wave spectral absorption of CO2 is essentially saturated. Consequently, yet more atmospheric CO2 becomes vanishingly less relevant to a greenhouse effect (if at all). And when more atmospheric water…

DOE Green Energy Loans: $11.45 million per job and a rounding error’s worth of averted carbon emissions.

Guest Post by David Middleton The cost of each taxpayer-financed green energy job created since 2009: $26.32 billion divided by 2,298 jobs = $11.45 million per job… Green energy jobs and DOE loans are tallied under programs 1703 and 1705 on this list.

An Engineer’s Take On Major Climate Change

Guest essay by Ronald D. Voisin Let’s examine, at a high and salient level, the positive-feedback Anthropogenic Global Warming, Green-House-Gas Heating Effect (AGW-GHGHE) with its supposed pivotal role for CO2. The thinking is that a small increase in atmospheric CO2 will trigger a large increase in atmospheric Green-House-Gas water vapor. And then the combination of…

AGU says CO2 is plant food

Elevated carbon dioxide making arid regions greener 31 May 2013 AGU Release No. 13-24 WASHINGTON, DC—Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth’s atmosphere. Now, a study of…

Premature 400 PPM fail-a-bration

It seems we didn’t reach 400PPM last week after all. The data has been revised. Ooops. ‘Carbon dioxide measurements in the Earth’s atmosphere did not break the symbolic milestone of 400 parts per million at a Hawaiian observatory last week, according to a revised reading from the nation’s climate observers.

The curious case of rising CO2 and falling temperatures

Guest essay by Tony Brown Some readers might recall my recent article ‘The Long Slow Thaw?’ In this I reconstructed Central England temperature to 1538 from its current instrumental date of 1659. I was surprised by two notable periods of warmth around 1630 and 1530. I am indebted amongst other material, to Phil Jones excellent…

Modeling future CO2 sequestration

From the Potsdam Institute for Climate Impact Research (PIK) CO2 removal can lower costs of climate protection According to the analysis, carbon dioxide removal could be used under certain requirements to alleviate the most costly components of mitigation, but it would not replace the bulk of actual emissions reductions. “Carbon dioxide removal from the atmosphere…

‘Carbon’ to blame for giant crabs

CO2, is there anything it can’t do? Add it to the list. Over at WaPo, they call them “supersized”. From Counsel and Heal News (h/t to Gene Doebley): Carbon To Blame for Oversized Blue Crabs The use of genetic engineering or steroid enhancements to enlarge certain food products has been popular but highly controversial in…

A misinterpreted claim about a NASA press release, CO2, solar flares, and the thermosphere is making the rounds

I loathe having to write this story because I truly dislike giving any attention to the people who are known as the “slayers” from the “Slaying the Sky Dragon” book. They now operate under the moniker of “Principia Scientific”. But, somebody has to do it because some really bad mangling of the intent of a…

Dispelling myths about global warming

CO2 did not drive the rapid warming of the 20th century. Story submitted by Stan Robertson The difference between a good idea and a bad idea is often a quantitative matter. For example, many people would think it a good idea to replace internal combustion engines with electric motors. But if the intent is to…

NASA satellite data shows a decline in water vapor

Guest post submitted by Ken Gregory, Friends of Science.org An analysis of NASA satellite data shows that water vapor, the most important greenhouse gas, has declined in the upper atmosphere causing a cooling effect that is 16 times greater than the warming effect from man-made greenhouse gas emissions during the period 1990 to 2001. The…
