The research described in Miller's new paper (incidentally, well written and readable) is impressive. Over three field seasons 2005-2010, the team studied ancient dead moss that had been newly exposed at the margins of retreating Baffin Island ice caps. Because the dead moss erodes quickly or is covered by new growth once it has been exposed, the researchers start with unusually precise dating for when the ice melted back at that point. They used radiocarbon methods to estimate when the moss had last been alive -- that is, when it had become covered by ice.
With moss collections from the margins of many different ice caps, four of them predating the Holocene, they have a rich dataset that supports a strong conclusion.
The age distribution of 145 radiocarbon-dated rooted plants that were exposed by ice recession in the year of collection along the highlands of Baffin Island, Arctic Canada, demonstrates that several ice caps are now smaller than at any time in more than 44 ka. There has been no intervening century during which summer warmth exceeded that of the last ~100 years. This is the first direct evidence that contemporary warmth in the Eastern Canadian Arctic now exceeds peak warmth of the early Holocene, when summer insolation across the region was ~9% greater than present. Recent laser altimetry data [Webb et al., 2009] indicates that ice bodies are losing mass at all elevations; hence, they are still adjusting to current summer temperatures. These findings add additional evidence to the growing consensus that anthropogenic emissions of greenhouse gases have now resulted in unprecedented recent summer warmth that is well outside the range of that attributable to natural climate variability.

I would like to see someone trying to explain for example general relativity to the chief. I guess though that trying to explain a second order equation would give the same result.
The quote don't seem to be from Einstein.

There are no sources that show that Einstein ever said or wrote that sentence.

It's like watching a clown car.
Chuff is driving.
Rong is in the back trying to pass out beers and drinking whiskey - completely clueless as to where they are headed.
Sketch is next to Rong telling jokes.
Rick is in the passenger seat with the map giving directions.
Every once and a while they pick up a hitch hiker who sits bitch.
Problem is Chuff took too many of rongs beers and is hammered, Sketch is telling bad jokes and nobody is listening and Rick is holding the map upside down. Instead of driving away from the cliff they are headed towards it.

Hey Chuff... if you don't realize I know it's not a fish and it's a dolphin then you are more of an idiot that any of us could imagine.
Also, if you paid any attention you'd know why the title of the movie is Blackfish.

But that's how the denier game works: They seize on a small errors and inconsequential factual inconsistencies in a piece of climate research and use it to discredit the science and reassure people that climate change is no bid deal. In the 2007 Assessment, for instance, the authors and reviewers overlooked a sentence that asserted the Himalayan glaciers would vanish be 2035 -- an obvious misstatement, which deniers seized and used to suggest that the entire assessment was bunk.... It's like finding a misspelling in the Manhattan phone book and then declaring the whole book useless.
The second issue that has come up is the question of a "hiatus," or pause in the surface-temperature warming. Texas Sen. Ted Cruz recently proclaimed that "there has been no recorded warming since 1998." Not exactly, Ted. According to the IPCC, the rate of warming at the planet's surface is lower over the past 15 years, but warming has not stopped. In fact, since the 1950's each successive decade has been hotter than the last, and the 2000s were the hottest decade since modern record-keeping began in 1880.
To former IPCC chair Watson, it is crucial that these criticisms not go unanswered. "The IPCC needs to have an answer for this," he says. "They need to be prepared." But in Santer's view, climate science is rapidly approaching the point where it is immune to these kinds of critiques: "Up until now, the criticism has been that climate science is like a house of cards, and that if you pull out one or two sets of data, it all collapses. That narrative has been refuted. The Fifth Assessment shows that warming has a physical and internal consistency - it's warming in the deep ocean, in the intermediate ocean and in the lower atmosphere. Sea level is rising. Arctic sea ice is retreating. The observational evidence for human-caused warning is overwhelming, compelling and irrefutable."
On the Koch's
With a combined worth estimated in the tens of billion$, the super-conservative industrial magnates with vast holding in the energy industry are major funders of climate-change skepticism. Their latest move: Via the proxy group Americans for Prosperity, they have persuaded more than 400 members of the current Congress to sign a "No Climate Tax" pledge to oppose any use of government dollars to fund climate efforts that does in include offsetting tax cuts.
!~~~!
Now, who do you think those tax cuts help the most?

Our energy use and habits, as well as those of much of the rest of the world, can be observed on this website, which has incredibly rich data.
The Energy Information Administration:
http://www.eia.gov/
If alternatives cost more than oil, the mere power of demand will keep our consumption the highest in the world. I wish that we were altruists, but we aren't. Everything around you has been touched by fossil fuels.
Rail is the most efficient. Air travel is the worst. Americans use far too much oil. We could cut our consumption by a third just by a change in habits. Jimmy Carter accomplished this back in the seventies. By the time Reagan had been in office a few years, the Saudi's were flooding the market to punish OPEC "cheaters" and with the cheap oil, we stopped conserving and rapidly changed our habits right back.
That website explains how energy markets work. I highly recommend it, as well as a book called "The Prize" to anyone with more than a passing interest in how and why we use fossil fuels.
