All you have to do is look at the results of the Medieval Warming Period.

Google some pictures of the Canadian Shield. I see LOTS of trees. Lots of water. Your entire post is hysterical ranting with a bunch of (incorrect) opinion and guessing.

I guess Ice Ages are easy to frivolously dismiss when you live in a place like Rio.

However, at our stage of understanding the system, climate engineering is probably not such a good thing to be doing. The planet isn't an experiment that we can easily clean up after we make a mess. We can't 'nuke it from orbit' just to make sure.

That is a major issue with the carbon sequesters and everybody else. We're really running in the dark. We need to put quite a bit more energy (pun intended) into understanding the system before we blithely go and tinker with it (like we are doing at present).

I think we agree on that point - that carbon legislation is not a good idea and that we should allow the economy to naturally evolve beyond the use of carbon. Not that legislation would work anyway, only the lowest emitters would sign on.

We can argue about whether or not the Earth is warming/cooling and whether that warming/cooling is due to man, but the AGW Alarmist arguments totally break down when they get into value judgements about the supposed facts.

The only real fact is that a person's opinion that warming and adding CO2 is beneficial is every bit as valid as someone saying it's not.

Submission + - FCC posts its 400-page net neutrality order (cnet.com)

jriding writes: Simply titled "Open Internet FCC-15-24A1," the order runs 400 pages.
The actual text of the new rules is only 305 words long.
Wheeler said reclassifying broadband as an utility gives the FCC its best shot at withstanding legal challenges. The courts have twice tossed out earlier rules aimed at protecting Internet openness. The FCC chairman has said repeatedly the agency does not intend to set rates or add new taxes to broadband bills. More than 100 pages of the 400-page document released Thursday explain that forbearance.

AT&T had hinted it would file a lawsuit once the new rules become public. The company's chief lobbyist, Jim Cicconi, didn't indicate Thursday when or even if AT&T would sue — only that the battle is far from over.

"Unfortunately, the order released today begins a period of uncertainty that will damage broadband investment in the United States," Cicconi said. "Ultimately, though, we are confident the issue will be resolved by bipartisan action by Congress or a future FCC, or by the courts."

Submission + - Ganymede's underground salt water ocean

schwit1 writes: By measuring the interaction of Jupiter and Ganymede’s magnetic fields, scientists have been able to estimate the size of the salt water ocean in Ganymede’s interior.

A team of scientists led by Joachim Saur of the University of Cologne in Germany came up with the idea of using Hubble to learn more about the inside of the moon. “I was always brainstorming how we could use a telescope in other ways,” said Saur. “Is there a way you could use a telescope to look inside a planetary body? Then I thought, the aurorae! Because aurorae are controlled by the magnetic field, if you observe the aurorae in an appropriate way, you learn something about the magnetic field. If you know the magnetic field, then you know something about the moon’s interior.”

If a saltwater ocean were present, Jupiter’s magnetic field would create a secondary magnetic field in the ocean that would counter Jupiter’s field. This “magnetic friction” would suppress the rocking of the aurorae. This ocean fights Jupiter’s magnetic field so strongly that it reduces the rocking of the aurorae to 2 degrees, instead of 6 degrees if the ocean were not present. Scientists estimate the ocean is 60 miles (100 kilometers) thick — 10 times deeper than Earth’s oceans — and is buried under a 95-mile (150-kilometer) crust of mostly ice.

That’s more water than contained in all of Earth’s oceans.

Submission + - Another Climate Change Driver: Orbital Variations Known as Milankovitch Cycles (pnas.org)

BCtoo writes: Fluctuating climate is a hallmark of Earth. As one transcends deep into Earth time, however, both the evidence for and the causes of climate change become difficult to establish. We report geochemical and sedimentological evidence for repeated, short-term climate fluctuations from the exceptionally well-preserved 1.4-billion-year-old Xiamaling Formation of the North China Craton. We observe two patterns of climate fluctuations: On long time scales, over what amounts to tens of millions of years, sediments of the Xiamaling Formation record changes in geochemistry consistent with long-term changes in the location of the Xiamaling relative to the position of the Intertropical Convergence Zone. On shorter time scales, and within a precisely calibrated stratigraphic framework, cyclicity in sediment geochemical dynamics is consistent with orbital control. In particular, sediment geochemical fluctuations reflect what appear to be orbitally forced changes in wind patterns and ocean circulation as they influenced rates of organic carbon flux, trace metal accumulation, and the source of detrital particles to the sediment.

Submission + - Highly efficient LED Filament Bulbs look almost exactly like an icandescent.

An anonymous reader writes: A recent article posted on a green building site gives a detailed analysis of a creative new kind of LED bulb that has been popping up Europe and Asia over the last year. They look almost exactly like Tungsten filament bulbs, require no heat sink, and offer extremely high efficiencies in the 100-120 lm/W range. The article describes their construction, compares them to conventional LED bulbs, and describes the result of a report by the Swedish Energey Agency that analyzed the performance of several brands of these these bulbs on the European market. Particularly interesting are links to teardown videos.
