Welfare spending now 25% of budget
The Obama years have seen unprecedented growth in spending on what used to be known as the federal "anti-poverty" or "welfare" programs: means-tested initiatives to provide food, health insurance, housing benefits, and income support to the poor. These programs certainly grew during the Bush administration, with spending increasing by a total of about $100 billion over that eight-year period ($12.5 billion per year in 2010 dollars). But that spending increased another $150 billion in just the first two years of the Obama administration.
The scale of these increases is staggering. In three years, from 2008 through 2010, total annual spending on welfare programs (in 2010 dollars) increased from $475 billion to $666 billion — a 40% increase after accounting for inflation. At a combined annual cost of two-thirds of a trillion dollars, these programs are now on the same scale as the defense budget ($693 billion), Social Security ($700 billion), and Medicare ($551 billion).

Marchetti's constant
You may find this interesting. Apparently the 30-minute commute may be a universal human constant. :)

Taste of science
The phenomenon is down to the fact that, although we have sensors on our tongue, eighty per cent of what we think of as taste actually reaches us through smell receptors in our nose.
The receptors, which relay messages to our brain, react to odours differently depending on which direction they are moving in.
"Think of a smelly cheese like Epoisses," Prof Smith said. "It smells like the inside of a teenager's training shoe. But once it's in your mouth, and you are experiencing the odour through the nose in the other direction, it is delicious.

Global warming/positive feedback
http://judithcurry.com/2012/08/24/a-modest-proposal-for-sequestration-of-co2-in-the-antarctic/

Near-IR video cameras aren't much different from visible-light ones. The one in this clip looks pretty sophisticated by comparison.
However I have to agree that the demonstration is nowhere near quantitative enough to infer much about absorption by CO2 of thermal radiation from Earth's surface. A far more accurate method is to calculate it line-by-line from theHITRAN line spectra tables.
However mere absorption of surface radiation is only about 6% of the impact of CO2 on global warming even in the no-feedback case. This is because what heats the Earth is reduction in outgoing longwave radiation (OLR) from the top of the atmosphere (TOA). Only 6% of that radiation is emitted by the surface, the rest is radiation from clouds and greenhouse gases in the atmosphere.
Clouds are not water vapor but droplets, which unlike water vapor but like the surface are much closer to being black body radiators. Although there is somewhat less CO2 above the clouds than above the surface (the difference being the amount of CO2 between the clouds and the surface), it's quite enough to absorb the same bands emitted by the clouds as those emitted by the surface.
Radiation from the atmosphere's greenhouse gases is narrow-band, even at sea level but increasingly so at higher altitudes as the effect of pressure-broadening decreases. Every greenhouse gas emits its own set of lines, and absorbs the same again, so there's a lot of emitting and absorbing going on in the atmosphere.
Looking down from above the atmosphere, a thermal imaging camera sees only the "top layer" of all this radiation. This layer is not sharply defined but rather is a separatephotosphere for each wavelength of IR. To quote the Wikipedia article, "The photosphere of an astronomical object is the region from which externally received light originates." Wavelengths that are absorbed more strongly create more opaque and therefore higher-altitude photospheres. The further below the photosphere, the lower the probability that a photon from that depth will escape to space. The probability is nonzero however no matter how deep, whence the indistinctness of each photosphere.
What increasing any greenhouse gas does is to make it more opaque, thereby raising the altitude of the photosphere associated with each wavelength at which that gas absorbs and emits. The higher you go the colder, namely 10 C/km for dry air (the Dry Adiabatic Lapse Rate or DALR) all the way down to 5 C/km for saturated air (the Moist Adiabatic Lapse Rate or MALR) when very warm. Hence a higher photosphere is colder. And since radiation follows the Stefan-Boltzmann law, the amount of radiation falls off as the 4th power of this decreasing temperature.
Higher temperatures raise the water vapor in the atmosphere. Hence heating the atmosphere by increasing the CO2 will increase water vapor, another greenhouse gas, which in turns heats the atmosphere even more. This vicious cycle is called a positive feedback, and is believed to add considerably to the basic no-feedback greenhouse effect attributable to CO2.
Richard Feynman said of quantum mechanics that if you think you understand it then you don't. The greenhouse effect is not quite that bad, but it runs a close second. John Nielson-Gammon has offered "The Best Ever Description of the Atmospheric Greenhouse Effect". I don't know if my account above is as good, but it's only half the length.

Gold standard
http://www.econbrowser.com/archives/2012/09/return_to_the_g.html
But the essence of a gold standard is that the units used in the above graph would become the units in which wages and prices would get reported and negotiated. Under a gold standard, a dollar always means the same thing in terms of ounces of gold that it would buy. So for example, if the dollar price of gold today was the same as it was in January 2000 ($283/ounce), and if the real value of gold had changed as much as it has since then, the dollar wage that an average worker received would need to have fallen from $13.75/hour in 2000 to $3.45/hour in 2012.
And the problem with that is, for a host of reasons ranging from minimum wage legislation, bargaining agreements and contracts, institutions, and human nature, it is very, very hard to get workers to accept a cut in their wage from $13.75/hour to $3.45/hour. The only way it could possibly happen is with an enormously high unemployment rate for a very long period of time. This strikes most of us as a pretty crazy policy proposal.
[snip: discussion showing that gold demand is not U.S.-driven, and thus that a gold standard for the dollar would not have prevented this depreciation]
