Net Neutrality Is 'Marxist,' According To a Koch-Backed Astroturf Group

riverat1 Re:What's so American (489 comments)

I don't think QoS violates net neutrality. I don't have any problem with expediting certain kinds of packets that are time critical. The problem comes when you do it only for your own packets or the packets of people who have paid you to expedite them to the detriment of other producers of those kind of packets.

Climate Scientist Pioneer Talks About the Furture of Geoengineering

riverat1 Re:We can learn from volcanoes. (138 comments)

The problem with injecting SO2 into the stratosphere is that you can never stop doing it as it has a limited lifetime in the atmosphere and as more and more CO2 is in the atmosphere you would have to increase it. Who's going to pay for that indefinitely into the future? On top of that the SO2 reduces the sunlight hitting the Earth which will reduce photosynthesis and thus agricultural productivity.

Climate Scientist Pioneer Talks About the Furture of Geoengineering

riverat1 Re:Cooling is worse then warming. (138 comments)

We know there is an ice age tipping point just a few degrees colder then present. Geo-engineering could fuck us all if they trust a climate model that overestimates.

I guarantee to you that no matter what we do the Earth will not plunge into an ice age in your lifetime or even your grandchildren's lifetimes. It takes multiple centuries for such a thing to even get going and millennia to fully develop. It is easily countered just by increasing greenhouse gases in the atmosphere.

Net Neutrality Is 'Marxist,' According To a Koch-Backed Astroturf Group

riverat1 Re:If we let the free market sort it out... (489 comments)

If we let the free market sort it out, no doubt Consumer Reports will print an article revealing which ISPs deliver Netflix content at good speeds, and which ISPs deliver Netflix content at lousy speeds.

That's just fine if I have my choice of ISP's to select from but I'm basically limited to two (Comcast or Quest). What I'd prefer is that the cable into my house is treated as a public utility that any ISP can avail themselves of. That would spur real competition between ISP's to get my business.

riverat1 Re:Paying by the MB (489 comments)

Net neutrality is not about the end user paying the same amount regardless of bandwidth usage. It's about the ISPs not treating content providers differently based on their competition with the ISP, their content or charging them extra when it's the end user making the demand. I have no problem with the end user paying for their level of bandwidth usage.

NRC Analyst Calls To Close Diablo Canyon, CA's Last Remaining Nuclear Plant

riverat1 Re:In other news... (216 comments)

Solar panels have just recently become self sustaining (where they create more energy than is needed to make them).

Ignoring the other issues with your post that statement is just plain silly. You're saying that over the (at least) 20-30 year life span of a solar PV panel it just barely produces more power than it took to build it. I'd like to see you try and justify that statement with actual facts.

Numerous Methane Leaks Found On Atlantic Sea Floor

riverat1 Re:Feedback loops (272 comments)

There are factors in the current warming that are quantifiably different than those other cycles you're talking about. The high level of CO2, the rate of change and the state of Milankovitch cycles for instance.

Numerous Methane Leaks Found On Atlantic Sea Floor

riverat1 Re:Feedback loops (272 comments)

To your specific point, we even have several historical examples in the ice records of (geologically) sudden 'pulses' in CO2 and temperature to levels comparable or exceeding today.* In every case the system has then returned to an equilibrium....DOZENS of times over the past couple of million years. The feedback loops you talk about are real; the cataclysmic FUD you're talking about negative feedback is, quite evidently, not.

There is little or no evidence that CO2 levels have been above about 300 ppm in the past several million years. They are now about 400 ppm so you have to go back more than 5 million years or so to find a comparable level.

As far as feedbacks and the cycles of the ice age go, the main driver appears to be orbital variations (Milankovitch Cycles) which are definitely not a feedback. Once the Milankovitch Cycles kick things off then various feedbacks come in to play.

Numerous Methane Leaks Found On Atlantic Sea Floor

riverat1 Re:Feedback loops (272 comments)

On thing that people forget is that as latitude increases the available land decreases. That is somewhat mitigated in the Northern Hemisphere by the continents getting wider further north. The formula for the circumference of a sphere at any angle from the equator is C = 2 pi r cos(angle). The circumference of the Earth at the Equator is about 40,000 km, at 45 degrees (where I live) it's about 28,337 km, at 60 degrees it's about 20,000 km, half the equatorial circumference.

riverat1 Re:Feedback loops (272 comments)

There's no need to "defend the moron climatologists" since they not the ones making those claims. There are plenty of people on the AGW is happening side who are getting overwrought about methane but most scientists studying the subject think it's a minor issue compared to CO2. It's something worth paying attention to but the chances of a catastrophic release from undersea methane deposits appears to be pretty remote.

Cause of Global Warming 'Hiatus' Found Deep In the Atlantic

riverat1 Re:Heat pumps (432 comments)

Yeah i never understood how th atmospheric temperature could remain constant but the ocean temperatures be continually rising from heat input from the atmosphere.

The major source of heat in the oceans is from absorbed sunlight. Some of that heat gets transferred to the atmosphere by convection (evaporation) and as the rate varies more or less heat remains in the oceans. In this case more of the heat is getting sucked down by oceanic currents and less is going into the atmosphere.

Extreme Hot Temperature Days Increase Despite Warming "Hiatus"

riverat1 riverat1 writes  |  about 5 months ago

riverat1 (1048260) writes "A new study published in Nature Climate Change (pay walled) finds that despite the "hiatus" in global temperature rise the the area and time span of extreme heat days continues to rise. As explained in an article at Phys.org temperatures for every day were compared to the same calendar day from 1979 to 2012 and the hottest 10% of days were classified as hot temperature extremes. They found on average extremely hot events are affecting more than twice the area they did 30 years ago and the upward trend in the number of days and area affected persisted right through the warming "hiatus".

"Our analysis shows there has been no pause in the increase of warmest daily extremes over land and the most extreme of the extreme conditions are showing the largest change," said Dr Markus Donat.

"Another interesting aspect of our research was that those regions that normally saw 50 or more excessive hot days in a year saw the greatest increases in land area impact and the frequency of hot days. In short, the hottest extremes got hotter and the events happened more often."

Comet ISON Nears Date With Sun

riverat1 riverat1 writes  |  about 9 months ago

riverat1 (1048260) writes "Now visible in the morning sky comet ISON will swing around the Sun on November 28. ISON will pass 730,000 km above the surface of the Sun at closest approach (Mercury's perihelion distance is 46 million km). If it survives its near brush with the Sun it could provide a spectacular sky show from December into January. This NASA timeline shows that ISON will be the most observed comet ever as instruments ranging from a balloon carried telescope to the Hubble Space Telescope to the STEREO satellites will be brought into play. Lowell Observatory astronomer Matthew Knight lays out three possibilities for ISON, spontaneous disintegration before it gets to the Sun (less than 1% chance), disintegration as it rounds the Sun or survival. If it survives its closest approach to Earth will be on December 26 at about 1/3 of an AU."

NWS Announces Big Computer Upgrade

riverat1 (1048260) writes "After being embarrassed when the Europeans did a better job forecasting Sandy than the National Weather Service Congress allocated $25 million ($23.7 after sequestration) in the Sandy relief bill for upgrades to forecasting and supercomputer resources. The NWS announced that their main forecasting computer will be upgraded from the current 213 TeraFlops to 2,600 TFlops by fiscal year 2015, over a twelve-fold increase. The upgrade is expected to increase the horizontal grid scale by a factor of 3 allowing more precise forecasting of local features of weather. The some of the allocated funds will also be used to hire some contract scientists to improve the forecast model physics and enhance the collection and assimilation of data."

BEST finds surface temperature changes track GHG emissions and volcanoes

riverat1 (1048260) writes "The Berkeley Earth Surface Temperature studies latest release finds that land surface temperature changes since 1750 are nearly completely explained by increases in greenhouse gases and large volcanic eruptions. They also said that including solar forcing did not significantly improve the fit. Unlike the other major temperature records BEST used nearly all available temperature records instead of just a representative sample. Yet to come is an analysis that includes ocean temperatures."

Sea Level Rise Can't be Stopped

riverat1 riverat1 writes  |  more than 2 years ago

riverat1 (1048260) writes "Sea level rise won't stop for several hundred years even if we reverse global warming according to a study published in the journal Nature Climate Change. As warmer water is mixed down into the oceans it causes thermal expansion of the water. Under the best emissions scenario the expected rise is 14.2 cm, under the worst 32.2 cm in 2100 (6 & 13 inches) from thermal expansion alone. Any glacial/ice sheet melt and water pumped from aquifers is on top of that. An easier to read summary is available at Reuters."

Predator Drone Helps Nab Cattle Rustlers

riverat1 riverat1 writes  |  more than 2 years ago

riverat1 (1048260) writes "KTLA reports police in North Dakota arrested 3 men accused of cattle rustling with the help of a Predator B drone from nearby Grand Forks AFB. The sheriff of Nelson Country was chased off by 3 armed men when he went to serve a warrant so he came back the next morning with reinforcements including the drone which, while circling 2 miles overhead, was able to determine the whereabouts of the men on their 3,000 acre spread and the fact that they were unarmed. A SWAT team quickly moved in and apprehended the men. Local police say they have used the Predator drones for at least 2 dozen surveillance flights since June. The FBI and DEA have used the drones for domestic investigations as well.

Dropping CO2 levels caused Antarctic ice sheet to

riverat1 riverat1 writes  |  more than 2 years ago

riverat1 (1048260) writes "In a news release from Purdue University a new study finds that CO2 level dropping below ~600 ppmv lead to the formation of the Antarctic ice sheet about 33.7 million years ago. The team studied geochemical remnants of ancient algae from cores drilled in geologically stable areas of the ocean floor. The focus was on two sites in the tropical Atlantic Ocean. Mark Pagani, the Yale geochemist who led the study cautioned it doesn't necessarily mean the ice sheet will melt at 600 ppmv of CO2 and said even if we reach the tipping point it will take thousands of years to completely melt it. The study is published in Science Magazine (paywalled)."

The Strange Birth and Long Life of Unix

riverat1 riverat1 writes  |  more than 2 years ago

riverat1 (1048260) writes " The classic operating system turns 40, and its progeny abound.

After AT&T dropped the Multics project in March of 1969 Ken Thompson and Dennis Ritchie of Bell Labs through a combination of discarded equipment and subterfuge continued to work on the project eventually writing the first programming manual for System I in November 1971. A paper published in 1974 in the Communications of the ACM on Unix brought a flurry of requests for copies. Since AT&T was restricted from selling products not directly related to telephones or telecommunications they released it to anyone who asked for a nominal license fee. At conferences they displayed the policy on a slide saying "No advertising, no support, no bug fixes, payment in advance." From that grew an ecosystem of users supporting users much like the Linux community. The rest is history."

A game-changing Optical Cavity Furnace developed by the U.S. Department of Energy's National Renewable Energy Laboratory uses optics to heat and purify solar cells at unmatched precision while sharply boosting the cells' efficiency.

So states a release by the NREL. The furnace uses about half the energy of a conventional thermal furnace, costs one quarter to one half as much and processes wafers in a significantly shorter time. Researchers ultimately expect to be able to improve solar cell efficiency by about 4% using the furnace."

NASA explains sea level drop

An August 23, 2011 update from NASA's Sea Level Sentinels explains the shift from El Nino to La Nina in early 2010 led to changes in rainfall worldwide that produced massive flooding in places such as Australia and the northern Amazon basin. Data from the GRACE satellites shows that the missing water has piled up on the continents. But the drop won't last, water flows downhill and will eventually find its way back to the sea."

Real party animal helps study alcohol abuse

riverat1 (1048260) writes "From TFA: "Prairie voles, by their nature, stick with one mate for life and devotedly care for babies together. But given alcohol to drink, many become staggering drunkards prone to stepping out on their partners."

A study of the voles at Oregon Health & Science University found that unlike the traditional lab rats or mice they prefer alcohol (6%) to plain water. A single vole will drink equal amounts of water and alcohol but two of them living together will party down taking 4/5ths of their drinks from the alcohol spiked bottle suggesting social bonds play as big a role on drinking behavior as they do in any college fraternity. The study may lead to insights in human drinking."

Air-fueled Battery Could Last Up to 10 Times Long

riverat1 riverat1 writes  |  more than 5 years ago

riverat1 writes "British researchers at the University of St. Andrews are investigating technology that could lead to longer lasting, lighter and cheaper lithium batteries. The battery uses oxygen from the air as a re-agent and replaces the lithium cobalt oxide cathode with porous carbon. So far they have more than tripled the capacity and are targeting a 5-10 fold increase in storage capacity. The battery could have applications all the way from personal electronics to vehicles up to storage of power for later use when the sun isn't shining and the wind isn't blowing."
