Don't think you could have given a better segue. Of course there's no way of knowing from the article linked if it will be a useful technology. Maybe we could pit the fossil fuel companies against the artificial leaf companies, and when the climate starts cooling off from pulling all the CO2 out, the fossil fuel companies can crank back up and inject some more CO2 back in to warm things up... And, just wondering, real leaves take hydrogen from water and carbon from the atmosphere to build their tissues, so I would suppose that there's a pretty big water bill that goes with the 'process'. And then what to do with that extra O2. I guess we'll be back to 3 foot dragonflies. The bug poison companies will have a field day. Can you tell I'm being a little facetious?

Seriously though, maybe there might be a useful application somewhere in there, but the lack of any listing of negative effects certainly throws up some question marks, at least in my mind. Is it just that the idea is so new that they've not investigated the possibilities? Is the author reporting with a bias (it seemed so to me), and if not why didn't he report any information on, say, the materials used in the process, or their availability? Or is it really all positive with no negative effects except to those of the fossil fuel interests? If that were true, I'd certainly be queuing up for some of the fairy dust.

And to beat a dead horse (more like an unborn one around here though), technology has a proper place, but as has been amply illustrated by history, without accompanying social, economic and political considerations, it's role in solving this problem will be marginal at best.

Which is of course one of the reasons we find ourselves in this position now.

Historical Records Miss a Fifth of Global Warming | NASA/JPL

(since this is a Government study I guess I can post the whole article without incurring the wrath of the moderators)

Quote:
A new NASA-led study finds that almost one-fifth of the global warming that has occurred in the past 150 years has been missed by historical records due to quirks in how global temperatures were recorded. The study explains why projections of future climate based solely on historical records estimate lower rates of warming than predictions from climate models.

The study applied the quirks in the historical records to climate model output and then performed the same calculations on both the models and the observations to make the first true apples-to-apples comparison of warming rates. With this modification, the models and observations largely agree on expected near-term global warming. The results were published in the journal Nature Climate Change. Mark Richardson of NASA's Jet Propulsion Laboratory, Pasadena, California, is the lead author.

The Arctic is warming faster than the rest of Earth, but there are fewer historic temperature readings from there than from lower latitudes because it is so inaccessible. A data set with fewer Arctic temperature measurements naturally shows less warming than a climate model that fully represents the Arctic.

Because it isn't possible to add more measurements from the past, the researchers instead set up the climate models to mimic the limited coverage in the historical records.

The new study also accounted for two other issues. First, the historical data mix air and water temperatures, whereas model results refer to air temperatures only. This quirk also skews the historical record toward the cool side, because water warms less than air. The final issue is that there was considerably more Arctic sea ice when temperature records began in the 1860s, and early observers recorded air temperatures over nearby land areas for the sea-ice-covered regions. As the ice melted, later observers switched to water temperatures instead. That also pushed down the reported temperature change.

Scientists have known about these quirks for some time, but this is the first study to calculate their impact. "They're quite small on their own, but they add up in the same direction," Richardson said. "We were surprised that they added up to such a big effect."

These quirks hide around 19 percent of global air-temperature warming since the 1860s. That's enough that calculations generated from historical records alone were cooler than about 90 percent of the results from the climate models that the Intergovernmental Panel on Climate Change (IPCC) uses for its authoritative assessment reports. In the apples-to-apples comparison, the historical temperature calculation was close to the middle of the range of calculations from the IPCC's suite of models.

Any research that compares modeled and observed long-term temperature records could suffer from the same problems, Richardson said. "Researchers should be clear about how they use temperature records, to make sure that comparisons are fair. It had seemed like real-world data hinted that future global warming would be a bit less than models said. This mostly disappears in a fair comparison."

Breakthrough solar cell captures CO2 and sunlight, produces burnable fuel | University of Illinois at Chicago
Quote:
Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy.

The finding is reported in the July 29 issue of Science and was funded by the National Science Foundation and the U.S. Department of Energy. A provisional patent application has been filed.

Unlike conventional solar cells, which convert sunlight into electricity that must be stored in heavy batteries, the new device essentially does the work of plants, converting atmospheric carbon dioxide into fuel, solving two crucial problems at once. A solar farm of such “artificial leaves” could remove significant amounts of carbon from the atmosphere and produce energy-dense fuel efficiently.

“The new solar cell is not photovoltaic — it’s photosynthetic,” says Amin Salehi-Khojin, assistant professor of mechanical and industrial engineering at UIC and senior author on the study.

“Instead of producing energy in an unsustainable one-way route from fossil fuels to greenhouse gas, we can now reverse the process and recycle atmospheric carbon into fuel using sunlight,” he said.

While plants produce fuel in the form of sugar, the artificial leaf delivers syngas, or synthesis gas, a mixture of hydrogen gas and carbon monoxide. Syngas can be burned directly, or converted into diesel or other hydrocarbon fuels.

The ability to turn CO2 into fuel at a cost comparable to a gallon of gasoline would render fossil fuels obsolete.[...]

“Nanostructured transition metal dichalcogenide electrocatalysts for CO2 reduction in ionic liquid” is online at Science.

Ah, but have you already forgotten? If we natter our way into solving GW, then we will in fact have solved cancer . . . and terrorism . . . and poverty . . . social injustice . . . economic inequality . . . racial tensions . . . reparations for past misdeeds . . . and [insert grievance here].

The 10 most startling facts about climate in 2015 — the warmest year on record | Washington Post
Quote:
Last year was unequivocally the warmest year on record for Earth. The National Oceanic and Atmospheric Administration Tuesday released a 300-page report documenting the historic warmth as well as scores of other aspects of 2015’s climate.

The hefty report, State of the Climate in 2015, was produced by more than 450 scientists from 62 countries around the world — more than any previous edition...

1. The global temperature was the highest on record...

2. The average ocean surface temperature was warmest on record...

3. Upper ocean heat content was highest on record...

4. Global sea level was highest on record...

5. The El Niño event was among the strongest on record...

6. Greenhouse gases were highest on record...

7. Record number of major tropical cyclones in Northern Hemisphere...

8. Arctic sea ice had its lowest maximum extent...

9. Glaciers continued shrinking...

10. Extreme temperatures were most extreme on record...

The MMGW Cultists are coming after your Steak!

“Agriculture today accounts for for one-third of global greenhouse gas emissions that promote global warming,” says Premack, “and half of those agriculture emissions come from livestock.”

Tofu only now for you Cultists, you can now add eating Meat to the list of Sins against mother Gia. Can you buy Meat Credits to offset your Sins?

They can't defend the crazy...so they divert the topic..ha ha ha..nice try.
You shouldn't have meat because WE DECIDE that it is bad for you, hurting the planet and WE as the MMGW Cultists have the right to lord over you and play your mother...ha ha ha...thanks for the illustrative example. Now head over to Estadios, Taco Fish, or Gina Burgers and have some meat.
