riverat1 Re:More proof (661 comments)

The last CO2 spike comparable to the current one was the PETM about 55.8 million years ago. The rate of carbon increase then appears to be at least 10 times slower than it is now and there was a mass extinction that accompanied it on benthic formaminifera. If the rate today was 10 times slower ocean life would have a much better chance of being able to adapt.

At Oxford, a Battery That's Lasted 175 Years -- So Far

riverat1 Re:Interstellar missions... (197 comments)

I don't think that's true. On a cloudy but windy night in the desert it doesn't get nearly as cold as on a clear windless night all other things being equal. In fact when I searched for "Desert nighttime cooling" here is the first thing that came up. It basically says under clear low humidity conditions at night radiative cooling is by far the the largest reason for cooling.

1 nanosecond..., honestly, that's typically British. In the US that battery would have been trashed already. The Brits are way too much attached to these long lasting historical figures. And royalty is another example.

Well, there is a light bulb in Livermore, CA that's been burning for 114 years. That hasn't been continuous as there have been some power outages and it's been moved a few times but the Livermore fire department seems pretty attached to it.

As I posted in a previous reply here is more of a big picture look at it:

GISTemp Decadal Global Surface Temperature
(Anomaly from 1950-1981 mean)

Decade_______Anomaly
1884-1893_____-0.26
1894-1903_____-0.25
1904-1913_____-0.40
1914-1923_____-0.28
1924-1933_____-0.17
1934-1943_____+0.00
1944-1953_____-0.03
1954-1963_____-0.02
1964-1973_____-0.02
1974-1983_____+0.10
1984-1993_____+0.24
1994-2003_____+0.46
2004-2014_____+0.59

As you can see the temperature rise from 1904-1903 to 2004-2014 is 0.99 degrees. Looking at it in decadal slices takes out the noise of year to year variability.

In the "big picture", there aren't many effective levers to pull to solve the warming problem, and the cost of pulling them is higher than the benefit.

Sez you. I've seen plenty of analyses from others including economists that say otherwise. At the rate we're going the "small amount" of warming over a few hundred years is still 10 times faster than the warming at the end of the last glaciation (ice age) and will cause sea level rise in 10's of feet.

I would probably vote no because solar and wind power are cheaper than nuclear. I'm not against nuclear power for environmental reasons although it has its problems there but because they are expensive. If someone develops inexpensive modular nuclear power units I'd be willing to see them deployed.

riverat1 Re:They already have (661 comments)

The 19334-1943 mean was the same as the 1951-1980 mean so 2014 is equally unusually hot (and in case you're going to ask what about 1930-1933 the 1924-1933 mean was -0.17 compared to the 1951-1980 mean). 10,000 years ago was at the tail end of the last glaciation (ice age in the common vernacular). From proxy research it appears to at most been about the same as the 1951-1980 average although of course the error margin is larger.

US Senate Set To Vote On Whether Climate Change Is a Hoax

riverat1 Re:Real question is: how much are humans changing (661 comments)

Climate change (global warming?) skeptics admit that humans are affecting climate, but the real question is "how much are humans changing it?". And while asking that, we should also ask:

    - Is the data used to measure climate accurate? (IPCC controversially says: "urban heat islands don't matter when measuring temperature")

No, the IPCC says we apply corrections for the UHI effect and the corrections have been scientifically validated.

- Is the climate actually warming? (satellite datasets say not for the last 18-25 years, terrestrial datasets say 14 years)

It takes a pretty narrow view to try and make that statement. Meanwhile the oceans continue to absorb more energy, sea level continues to rise and ice keeps melting, symptoms of a warming world.

- If there is warming, how much of it is caused by CO2 rises? (not much, since warming has "paused" while CO2 levels increased)

Which just shows that you don't understand the magnitude of natural variability is over 10 times the magnitude of the warming signal from CO2 and feedbacks. Eventually as the warming continues to rise it will overcome the vicissitudes of natural variability. The fact that 2014 is the warmest in the instrument record and it wasn't also an El Nino year indicates that's starting to happen.

- How accurate are the CO2-temperature feedback models? (not very, they have overestimated by 2-4x)

2-4 times is gross hyperbole. Temperatures are still within the uncertainty bands of climate model projections so it's impossible to say the models are wrong.

- How much of the CO2 rise is caused by humans?

Considering that the year to year increase in CO2 in the atmosphere is only about 45% of yearly output of human emissions the answer has to be 100%.

- What is the cost/benefit of lowering CO2 now vs delaying 50/100 years when tech will be more advanced?

If the possible bad effects of not reducing CO2 emissions are even moderately possible then risk management theory says it's far more costly to wait than to do something about it. Even now the cost of wind and solar power is starting to be competitive with existing electricity production so the cost really isn't that great. And the cost of renewables is still going down.

riverat1 Re:As real as old Saint Nick (661 comments)

For that particular example, I had in mind the University of California climatology department's models from the nineties. That's just one example, though - pick up any issue of Greenpeace magazine or any of All Gore's stuff that's had time to come true. You'll find plenty of claims about what will happen in twenty years or fifty years. Now that it IS twenty years later, we can see which of those are utter bullshit, and which aren't.

I challenge you to come up with a concrete example from the early 1990s that actually shows that. By concrete example I mean a paper or article from a researcher in the field. I'd be surprise, shocked even if your UofC anecdote is correct.

Yes, that NASA. Here is the full table for your perusal:

Probability of Warmest Year
2014___~38%
2010___~23%
2005___~17%
1998___~4%

So 2014 is about 1.6 times more likely to have been the warmest year than 2010.

You're getting lost in the details. If you just take the raw data without adjustments you'd be hard put to find much difference between them and the adjusted temperatures. Scientist make the adjustments to correct for known errors and make the temperatures more accurate for their scientific purposes. The different methods of doing this serve as a check on each other and even though they produce slightly different results they are in agreement within the margin of error.

Extreme Hot Temperature Days Increase Despite Warming "Hiatus"

riverat1 riverat1 writes  |  about a year 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 a year 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. 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  |  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

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

The Strange Birth and Long Life of Unix

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.
