Oso Disaster Had Its Roots In Earlier Landslides

riverat1 Re:a question.... (55 comments)

I seriously doubt those areas were under sea level during the last ice age. Sea level was several hundred feet lower at the time. But glacial deposits + rain is a good enough reason for the slide to have occurred.

The debate over climate change is..

riverat1 Re:n/t (278 comments)

Now, now - you need to do better than that. All you've done is declare to me that the evidence is in there somewhere for me to find.

Sounds to me like you want it all handed to you on a silver platter. Why should I do your work for you?

Mt. Pinatubo erupted in the southern hemisphere in 1991. Why don't I see a corresponding dip in the temperature data (in either of the Hadcrut4 data or the IPCC report)?

Actually Pinatubo is 15 degrees north of the Equator. You need to zoom in to see the details in the temperature record. Here is temperatures from GISSTEMP, HADCRUT4, UAH and RSS plotted from 1980 to 1999. They all clearly show a 2 to 3 year dip in temperatures after the 1982 eruption of El Chichon (in Mexico) and after the 1991 eruption of Pinatubo.

If pollution causes cooling, then the warming trend between 1910 and 1943 would have been a cooling trend.

Evidence? The degree of industrialization during and after WW II was much greater than before. Also, there was a marked increase in solar forcing from 1900 to around 1960. There were other factors too.

As any advocate would know, when you have a favorable outcome you want to show, you present the evidence most favorable to that outcome.

The authors of the IPCC AR5 WG1 report are all scientists working in the various fields presented in the report. They are unpaid by the IPCC other than to cover travel and lodging expenses. You're accusing them of wanting a predetermined outcome rather than honestly presenting the science as they see it. The problem with that view is these are all smart guys. They know there is an underlying reality that science studies that can't be changed by opinions. That reality is there to be discovered by anyone who puts in the work to investigate it. They know that if they are wrong sooner or later it will be discovered. They know if they are found to have purposely manipulated the science for political reasons their reputations would be destroyed. I'm still waiting for someone to turn climate science on its head.

You and I both know that there are valid papers from opposing views that are not explained in that report.

There are very few papers that have an opposing point of view. Well less than 5% of papers published in the field.

We need more than a facial "scientific" demonstration to come to a rational conclusion.

I think you meant facile (or maybe farcial). You appear to be doing what you accuse scientists of doing. You have a predetermined outcome you want (or at least you believe the current science must be wrong) so you scientists must be doing the same thing. But as I said there is a reality behind it all that can't be changed. It's not something that is debatable. Why would any scientist worth the name do anything but follow the evidence where it leads?

The debate over climate change is..

riverat1 Re:n/t (278 comments)

Your expectation that if what climate scientists are saying is true then temperatures should rise in lockstep with changes in CO2 levels is unrealistic. Over the short run (less than around 30 years) other factors can override the slow but steady underlying signal of warming from CO2 and other greenhouse gases.

For instance during and after WW II there was a massive increase in industrialization with little in the way of pollution controls. That dumped a lot of aerosols into the atmosphere which reflected a lot of sunlight before it could reach the surface. Beginning in the late 1960's we instituted pollution controls that reduced the problem allowing the underlying signal to take over again. The industrialization of China and SE Asia over the past couple decades has had similar effects and they have yet to institute effective pollution controls.

Other natural factors that can affect the global warming signal on the short term include volcanoes (there was a measurable cooling effect from the eruption of Mt. Pinatubo in 1991), changes in the oceans (where over 90% of the heat from global warming goes) such as ENSO and the PDO.

Just because the temperature record doesn't show a steady rise in lockstep with CO2 rises doesn't mean the underlying signal isn't there.

As far as the IPCC report goes you need to dig deeper. The details are ultimately in the thousands of scientific papers cited by the report. The summaries are edited by politicians but the WG 1 report itself is written by scientists. They simplify their presentation to make it more accessible to non-scientists but as I say the real details are in the cited scientific papers.

No, I would not be that guy. You can go straight to the data sources and get the data and plot it on your own. It's going to take a lot more work though so I doubt you'll do that. You probably don't have the knowledge to use most of them. Here's some links:

New Map Fingers Future Hot Spots For U.S. Earthquakes

riverat1 Re:Protip (49 comments)

California

California has some pretty big earthquakes but for the really big quakes you need a subduction zone like the Cascadia that covers from just south of the Oregon border up to southern British Columbia or the Aleutian Megathrust zone off of southern Alaska. Those produce magnitude 9+ quakes like the one off of Indonesia a few years ago. Fortunately they don't happen that often.

riverat1 Re:For The Love of Glob! (552 comments)

I still didn't find any direct assertion that supports your claim there. But in the short run of the next 10-20 years the problem isn't acute and if that's all you care about SLR wouldn't be that big an impediment to buying such property. Personally I wouldn't think of buying any property that's less than around 50 feet above sea level on the west coast (where I live), as much for the potential tsunami danger as for sea level rise.

The amount of actual heat produced by burning stuff is miniscule compared to the energy added by greenhouse warming, about 0.028 W/m^2 vs. 2.9 W/m^2. It's not worth worrying about at this point.

riverat1 Re:n/t (278 comments)

I refer you to the IPCC AR5 Working Group 1 report to support my argument. If you want to debate the science of climate (rather than the political questions that arise from its implications) you need to do it in a scientific manner with an awareness of the science that's already been done. Bringing up the same old arguments that have been repeatedly refuted doesn't cut it.

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 8 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 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."

Sea Level Rise Can't be Stopped

riverat1 riverat1 writes  |  about 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

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."

NASA explains sea level drop

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."

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."
