CliSAP: Mr. Held, several hundred researchers worked for several years on preparing the recently published third part of the Assessment Report, without pay and on top of their normal duties. The result was a work over two thousand pages long. Was it worth it? An overview of the uncertainties when it comes to estimating investments in low carbon. Maybe there is room for computational management projects in there?

"What's new: Choi said that although some researchers have used natural photosynthetic units to enhance the light-harvesting abilities of nanomaterials, this is the first time anyone has used nanomaterials to enhance the function of photosynthetic units."

Interesting discussion is going about, on how work anxiety is spreading in academia, with possible mental consequences. And with robust links to the "Doing What You Love" motto of life/work. Could be proven an unsustainable model though. Recalling of Higgs' recent declaration, that today's Academia productivity demands would be hectic for him, could point to the direction of the problem and the solution...?

where "correct":: the time when the sun is at its maximum height at 12:00

Very comprehensive thanks to the narrator from EUMETSAT training office (plus aesthetically pleasing)

A wide scale 8 year experiment in China on combating desertification seems to have been successful. Instead of using cyanobacteria blooms in the sea, the tested method proposes to spray them on the boundaries of desert/farmland every few days, so that the carbon they capture stays on the ground. It is useful in fixing the organic material against wind erosion only complementary to planting hardy grasses. Very fast result, nevertheless. Could be classified as a geoengineering activity.

The natural multitaskers are profited the least from this configuration. And then there is Thijs

Bringing water to that supercritical phase (high pressurization and temperature) renders it into an oxidation agent of organic material with pure CO_2 and H2O as products. Less waste volume in the ISS. Also, all contained salts precipitate out at that phase.

As the researchers desribe, the aquifer found is defined as a basin filled with aged snow (firn) that was saturated with water trapped within its porous structure. More ice cores to study! But in that case the time sequence along the length of the cores - to be extracted- would not be monotonic, as was the case in the dry cores we analysed. That's because there is constant input of surface water percolating through the ice-sheet to reach the depth of the aquifer, and since it flows downward its temperature could affect its partial pressure => its vertical position along the core

Some sort of organic carbon has been detected by the sampling of Curiosity; the contamination source was isolated and the signal persists. The scientists suggest as a source meteorites transporting interstellar matter, or maybe some sort of ancient life whose biomass production only survived cosmic radiation as it was buried underground. a big deal: six relevant articles were published simultaneously online: http://www.sciencemag.org/site/extra/curiosity/index.xhtml?utm_content=&utm_medium=Facebook&utm_campaign=Science&utm_source=shortener

Another underestimated source of CO2, are turbulent waters. "The stronger the turbulences at the water's surface, the more CO2 is released into the atmosphere. The combination of maps and data revealed that, while the CO2 emissions from lakes and reservoirs are lower than assumed, those from rivers and streams are three times as high as previously believed." Alltogether the emitted CO2 equates to roughly one-fifth of the emissions caused by humans. Yet more stuff to model...

here is the nature paper : http://www.nature.com/nature/journal/v503/n7476/full/nature12760.html I appreciate Johannes' and Dario's jokes, since climate is the common ground that all of us can have an opinion, taking honours from experiencing weather. But, the same as if I am trying to make jokes for material science, or A.I. I take a high risk of failing(!) :-S Water is a greenhouse gas, rain rather releases latent heat to the environment in order to be formed, Johannes, nice trolling effort ;-) Between this and the next jokes to come, I would stop to take a look here, provided you have 10 minutes: how/where rain forms http://www.scribd.com/doc/58033704/Tephigrams-for-Dummies

I enjoy trolling conversations when there is a gain for both sides at the end :-) . I had to check upon some of the facts in order to explain my self properly. The IPCC report states the greenhouse gases here, and water vapour is included: http://www.ipcc.ch/publications_and_data/ar4/wg1/en/faq-2-1.html Honestly, I read only the abstract of the article you posted, which is a very interesting hypothesis on the mechanism of regulating sea surface temperature, but it is very localized to the tropics (vivid convection, storms) a region of which I have very little expertise, and is difficult to study because it has non-hydrostatic dynamics. The only thing I can comment there is that the authors define constant relative humidity for the bottom layer, supplied by the oceanic surface, which limits the implementation of the concept on other earth regions. Also, we may confuse during the conversation the greenhouse gas with the Radiative Forcing of each greenhouse gas: I see your point of the latent heat trapped in the water vapour, and I agree, but the effect of the water is that it traps even as latent heat an amount of LR that would otherwise escape back to space. That is the greenhouse gas identity and an image to see the absorption bands in the atmosphere and how important the water is, without vain authority-based arguments that miss the explanation in the end: http://www.google.nl/imgres?imgurl=http://www.solarchords.com/uploaded/82/87-33833-450015_44absorbspec.gif&imgrefurl=http://www.solarchords.com/agw-science/4/greenhouse--1-radiation/33784/&h=468&w=458&sz=28&tbnid=x2NtfKh5OPM7lM:&tbnh=98&tbnw=96&zoom=1&usg=__KldteWbV19nVPbbsC4jsOgzCK6E=&docid=cMRZ9f22jbtYPM&sa=X&ei=SwynUq2TMqiS0QXVq4C4Aw&ved=0CDkQ9QEwAw

Putting together the picture of how climate works. An informative slide that shows which are the climatic subsystems that can undergo(/have undergone in the past) bifurcations (Lenton et al., 2008 PNAS).

Atmospheric rivers, short-lived wind tunnels are created in the upper troposphere and carry vast amounts of water. They 'fuel' from the tropical Pacific reservoir and cause heavy precipitation events and even floods to mid-latitude land, as soon as they encounter the Sierra mountains. The new finding is that two inter-hemispheric climatic oscillation modes allow for their creation, as soon as they are found in a certain phase combination.

Luca Turin presents a theory according to which the sense of smell is aroused by molecular vibrations instead of the shape-based compatibility with receivers on the proteins.

Inserting a droplet of polymer enriched water into oil and manipulating its shape by applying an electric field. The shape remains intact after cease of the forcing. <br /> "Russell (...) points out that the advance holds promise for a wide range of different applications including in drug delivery, biosensing, fluidics, photovoltaics, encapsulation and bicontinuous media for energy applications and separations media."

Plastic needs a timescale of millenia to dissolve in the ocean and in the meantime it is accumulated in the water due to systematic dumping of garbage in the ocean since decades. Deploying buoyant devices at the location of the gyres (permanent circular currents in the ocean) is proposed for collecting the thin particles. The ambitious concept was developped by a Delft student, presented at a TEDx (see link), made a feasibility study through crowdfunding and now announces a public contest for developing mechanical parts of the harvesting system.

The laconic statement states that anthropogenic influence on climate is verified from combination of independent databases. More details on the physical base report to follow in 3 days.
