Extent of Antarctic Sea Ice Reaches Record Levels

riverat1 Re:Some thoughts (617 comments)

That graph is most assuredly not the South Pole or anywhere near it. The caption says "Southern Polar 70.0S to 60.0S". Very little of Antarctica is north of 70S. It's about 1,380 miles from 70S to 90S.

Wave Power Fails To Live Up To Promise

riverat1 Re:Mechanical stresses ... (195 comments)

As the others explained a larger wind turbine is more efficient, not just in harnessing the wind power but also in resources used to produce it. For example one big generator instead of 100 smaller ones. Another factor is that smaller wind turbines turn faster and so kill more birds.

Wave Power Fails To Live Up To Promise

riverat1 Re:Golden opportunity missed... (195 comments)

So you don't think anything is worth trying unless you can tell ahead of time if it's going to work or not? There's a lot of energy to be extracted from waves if we can figure out how to harness them.

riverat1 Re:Please See: (617 comments)

If your poorly constructed argument were correct, then the Earth's temperature would be increasing year upon year. However it is not, as the warmest year in recent records is 1998. We know from the fossil record that increased carbon dioxide levels are a response to global warming, not a driver

A more complete accounting of the energy balance of the Earth's geosystems includes not only the atmosphere but the oceans, land and biosphere. Natural variation will affect how energy is distributed between those areas. So even though surface atmospheric temperature may not be rising as steeply lately (and choosing 1998 is an extreme cherry pick) the oceans (where over 90% of the energy from global warming goes) have continued to warm up. Given the different heat capacity between air and water it doesn't take much of a change in ocean warming to have a major effect on atmospheric warming.

In fact, the Ozone hole was there the first time it was recorded.

Extent of Antarctic Sea Ice Reaches Record Levels

riverat1 Re:Warmists never bother debating anymore (617 comments)

Correct, however for those who do the maths, energy captured due to CO2 absorption (all else ignored) has a T^3 factor. Blackbody radiation (the heat emitted to space) has a T^4 component. When you do the maths, temperature rise is logrithmic with CO2 proportion. Basically, temperature rise is quoted for a doubling in CO2. Say 1.2 degrees - to get another 1.2 degrees, you need to double again etc.

Now to try to make it scarier, you can introduce feedback - so the hotter it gets, the rate of increase get faster to offset the logrithmic CO2/T. The trouble is that whilst the temperature increase due to CO2 has been tested time and again, and uses sound physics principles, the feedback is more or less guess work. Models are tweaked with new feedback terms until they match previous years...

You were doing so well then you just sailed right off the tracks. On what basis do you claim that feedback is more or less guesswork? Models are not tweaked to match previous years. Any adjustments are made on the basis of better understanding of the physics involved.

riverat1 Re:Time for new terminology (617 comments)

Given that natural sinks of CO2 absorb enough of it that the year to year rise in atmospheric CO2 is only about half of total human emissions per year it's your numbers don't add up. If those natural sinks didn't operate as they do the year to year rise in CO2 would be over 10 ppm per year or over 100 ppm per decade.

My point about cyanide wasn't that CO2 would directly kill anyone but that just because there is a small number doesn't mean the effect is small. There is no doubt that there have been some excess deaths around the world due to the effects of global warming caused by increased CO2. Absolutely no one believes that CO2 should be entirely eliminated from the atmosphere which would be impossible to do in any case. We just need to stop causing the level to rise.

Extent of Antarctic Sea Ice Reaches Record Levels

riverat1 Re:Time for new terminology (617 comments)

Estimated deaths for various future scenarios:

- Accidentally inducing an ice age (which can happen in as little as a year or two) from amelioration efforts: billions

Science says it's impossible for the Earth to plunge into a glaciation cycle with CO2 levels greater than about 250 ppm so no worry. A supermassive volcanic eruption or major asteroid strike might plunge us into a decade or two of cold temperatures that could kill millions or billions of people but it wouldn't plunge us into an ice age.

-Successful amelioration efforts backing off GW, with attendant damage to economic dynamism, leaving us with 2050 tech in 2100: hundreds of millions to billions

-GW with slow sea rise but continued powerful economy: Baseline against the ungodly losses of the other two scenarios, but level 2100 tech with its marvels (consider vs. 1900vs today)

I think you have that backwards. More like:
-Successful amelioration with lots of new investment in the technologies that we use to replace our dependence on fossil fuels.

-GW with shifting climates slowly degrading agricultural and natural systems make it increasingly impossible to feed everyone leading to massive starvation after they decimate their local ecosystems looking for food and billions die.

"Radically altering the composition of the atmosphere ..." Really? Imagine a stadium of 100,000 people, each assigned a molecule present in dry air. 79,090 would be nitrogen. 20,950 would be oxygen. 930 would be argon. 39 would be CO2. Of the 39 CO2 people, 36 would have resulted from natural activity, and 3 would be because of human activity. 3 out of 100,000 is not a radical change, especially when the fossil record shows concentrations in the 5000 ppm range.

You're numbers are a bit off. More like 40 would be CO2, 28 would be from nature and 12 would be from human activity.

Just because the concentration of CO2 in the atmosphere is small doesn't mean it isn't significant. If I put you in a room with a concentration of just 270 ppm of hydrogen cyanide gas you would be dead within minutes.

Your response is just makes it evident that politics are more important to you than the science. The various "dire" predictions are materializing on schedule or in some cases ahead of schedule and you would know that if you paid attention to the science. Yes, there have been a few hyperbolic statements here and there but they are not mainstream science.

BTW, Al Gore's place on the coast is far enough above sea level and won't have problems with SLR for several hundred years.

Sheesh! Sea ice has essentially zero effect on sea level whether it forms or melts. It's the land based ice like the Greenland and Antarctic ice sheets that have an effect on sea level. If you're not paying enough attention to the science to understand even that simple concept why should I think anything else you have to say is worth listening to.

Extreme Hot Temperature Days Increase Despite Warming "Hiatus"

riverat1 riverat1 writes  |  about 7 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 10 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."

The upgrade is expected to increase the horizontal grid scale by a factor of 3 allowing more precise forecasting of local features of weather.

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

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

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 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.
