60 Minutes of Real Climate Science

It's almost impossible for the average person with no science background to get good basic info about climate change (on TV or online). So, here's some information that you can rely on. First dispelling a popular myth, and then a lecture by Dr. M...

The decline in California’s cotton acreage

Inkstain (John Fleck) | 7 February, 2016
In his keynote at last week's Law of the Colorado River conference in Las Vegas, Metropolitan Water District General Manager Jeff Kightlinger pointed out something that's not gotten a lot of attention in discussions of California's drought - the extraordinary decline in that state's acreage of cotton. Cotton's gotten a bad rap in irrigation circles, because it's subsidized and thirsty. Despite those subsidies, as I've written, cotton acreage in Arizona has plummeted, which is why I don't see the cotton subsidy as a big piece of the western water problem. But I didn't realize the size the decline of California's cotton industry.

Version 3 of the Quaternary Active Faults Database of Iberia (QAFI) available

Paleoseismicity | 7 February, 2016
Great news reached us from Spain! Our colleague Julián Garcia Mayordomo spread the news that an updated version of the Quaternary Active Faults Database of Iberia (QAFI) is now available online. QAFI has a GoogleMaps-based interface with clickable features providing loads of content on fault geometry, fault mechanism, slip-rate, historical and pre-historical seismicity, geomorphology, compilers, further references and much more. Truly a wonderful tool, congratulations!

Pete's on watch

JOIDES Resolution Blogs | 7 February, 2016
I just realized that with the lost blogs of the first week, I also lost my tag photo, and sadly me with Safety Penguin was someone else's photo.  But this is a good one of me in my office here on the JR.  Today the Chief Scientists gave an excellent overview to all the crew of just exactly what we're looking for on this expedition and why.

Politics in a full world

Resource Insights | 7 February, 2016
When Scientific American published Herman Daly's "Economics in a Full World" in September 2005, few people knew what lay ahead: oil climbing to $147 a barrel, the relentless rise in global temperatures due to greenhouse gas emissions, the food riots of 2008 sparked by rising food prices, the economic crash that followed, and the development of an increasingly yawning gap between the rich and everyone else in subsequent years. For the vast majority of people on the planet, growth effectively stopped in 2008. Their incomes have essentially flatlined or declined.

Feb. 6, 2016 - hopefully the end of the technical difficulties!

JOIDES Resolution Blogs | 7 February, 2016
The faithful followers might have noticed that my blog disappeared for a day or so, and now the last half dozen dates are dated rather than titled.  There was a minor glitch in transferring from Exp. 360 to 361, so I've had to replace the entries (luckily I had them recorded elsewhere).  But now we're good to go.

Eruption on Sakurajima volcano, Japan.

Sciency Thoughts | 7 February, 2016
Sakurajima, an active volcano on Kyushu Island, Japan, underwent a spectacular eruption on Friday 5 February 2015, producing an ash column about 2.2 km in height as well as throwing incandescent material (glowing hot ash and/or rocks) several hundred meters from the crater. There are no reports of any damage or injuries following the event, but local authorities have placed a 2 km exclusion zone around the volcano as a precaution.

If Journalism is About Truth, Then Why Are Top Newspapers Knowingly Publishing This Lie

Three still missing following collapse at South African gold mine.

Sciency Thoughts | 7 February, 2016
Three people are still missing following a collapse at the Vantage Goldfields operated Makonjwaan Lily Gold Mine near Low's Creek in Mpumalanga at about 8.40 am local time on Friday 5 February 2015. The incident was reportedly caused by the failure of an underground pillar, which in turn led to a roof collapse, trapping 87 miners below ground. All of these workers have now been rescued successfully with only miner injuries, however the collapse also led to the formation of a sinkhole (surface hole created by the formation of a void bellow ground)which swallowed a mobile office building in which two women and a man were working, It is these three mine employees, understood to have been involved in issuing miners with safety equipment, that are still missing and are still being actively sought by rescue teams. All production at the mine has ceased until further notice, and workers are being offered trauma counseling.

Asteroid 2016 AK193 passes the Earth.

Sciency Thoughts | 6 February, 2016
Asteroid 2016 AK193  passed by the Earth at a distance of 9 157 000 km (23.8 times the average distance between the Earth and the Moon, or 6.12% of the average distance between the Earth and the Sun), slightly before 2.00 a m GMT on Saturday 30 January 2016. There was no danger of the asteroid hitting us, though had it done so it would have presented a considerable threat. 2016 AK193 has an estimated equivalent diameter of 71-240 m (i.e. a spherical body with the same mass would be 71-240 m in diameter), and an object towards the upper end of this range would pass through the atmosphere and directly impact the ground with a force of about 500 megatons (about 30 000 times the explosive energy of the Hiroshima bomb), causing devastation over a wide area and creating a crater over 3 km across, and resulting in global climatic problems that could last for years or even decades.

New On-line Classes and Models

RealClimate | 6 February, 2016
My free online class on Coursera.org entitled Global Warming I: The Science and Modeling of Climate Change has already served 45,000 people (started, not finished) in the four times that it's run. Now it's set up in a new format, called "on demand mode", which allows people to start, progress, and finish on their own calendars. This would be an advantage if a teacher wanted to use the material to supplement a class; there are no longer any time constraints built into the Coursera system to prevent that.
