Recursive Fury

"A theory quickly emerged: that believers in climate science had been the main people taking Dr. Lewandowsky’s survey, but instead of answering honestly, had decided en masse to impersonate climate contrarians, giving the craziest possible answers so as to make the contrarians look like whack jobs. So, a paper about a tendency among this group to believe in conspiracy theories was met by … a conspiracy theory." - Unlocking the Conspiracy Mind-Set [more inside]

The Ocean: world's biggest filter.

How can we get CO2 out of the atmosphere? Get it out of the sea first. Making jet fuel from seawater is a pretty cool -- albeit energy intensive -- trick. But applying the same science to scrub CO2 out of seawater, where it is more densely concentrated than in the atmosphere -- and, by doing so, to reduce atmospheric levels of CO2 back to acceptable levels -- that's a game saver. "what would it take to draw atmospheric carbon down to 350 ppm with just this technology? . . . we would require the power of about 700 AP-1000 nuclear reactors. At the Chinese cost of $1.3b apiece and an 80 year lifetime this would cost a bit over $1 trillion dollars. That sounds like a lot of money. But its only about the cost of America’s 2003 Iraq War spread over the century, so I guess it’s a question of priorities."

This one goes deep purple

It's so hot in Australia they've added a new color to the weather map, a Tasmania-sized deep purple blob 50 degrees or more (123 F). In the USA 2012 was the hottest year ever recorded, smashing through previous records by a healthy margin. 2012 was also the second-worst on a measure called the Climate Extremes Index, surpassed only by 1998. Globally, 2012 is expected to be ranked as the eighth-warmest year on record, with that announcement coming later in the month. "Climate change has had a role in this,” said Jake Crouch, a climate scientist at NOAA.

The greatest sandy disaster of our time

October 2012 is the 332nd consecutive month with an above-average temperature. If you were born in or after April 1985, if you are right now 27 years old or younger, you have never lived through a month that was colder than average. State of the Climate: Global Analysis October 2012 (NOAA). While $50 billion Sandy has had the spotlight, the biggest natural disaster of 2012 (in the US) has been the Great Drought still ongoing which is expected to cut America's GDP by 0.5 to 1% for the year. The death toll from the heat waves that accompanied this year's drought will exceed that of Sandy. This Sunday and Monday, Ken Burns premiers his new documentary "The Dust Bowl", on PBS. (via)

I love a sun-powered country, A land of deepening mines, of ragged nuclear plants, of biomass and hydropower

While developed countries are pondering whether they should sign up to The Kyoto 2 Protocol and cut greenhouse gas emissions by 5% by 2020, based on 2000 levels which may be of questionable impact, the tiny Pacific territory of Tokelau has ditched its primary source of electricity generation, costly diesel imports, in favour of 100% renewable solar power, becoming the first nation in the world to do so, at a time when the global energy systems of the 21C are struggling towards decarbonisation.

Extreme climate predictions the most accurate

A new study in which researchers have compared the last 10 years of actual climate data with the world's most sophisticated climate simulations and found the models predicting the most extreme global warming have been the most accurate in predicting the actual climate over the last 10 years. That means if those models continue to hold true, the world could be in for a devastating worst case of 4 to 6 degrees C by 2100. There are scientists who lay out the logic why human civilization could not survive. "If you have got a population of 9 billion by 2050 and you hit 4 degrees, 5 degrees or 6 degrees, you might have half a billion people surviving." (Previously; via)

"...do you really want a couple million eagles circling overhead?"

In 2003, the BBC reported that a population explosion of Great Gerbils had destroyed more than 4 million hectares of grasslands in China's north-western Xinjiang region -- an area about the size of Switzerland. By 2005 the damage covered 5 million hectares, and the Xinjuang Regional Headquarters for Controlling Locusts and Rodents were reported to be breeding and attracting pairs of golden eagles to curb the gerbil population.

"all gone by 2015"

While the 2007 IPCC report showed Arctic sea-ice still present in 2100, it is now an unfolding "global disaster" according to Cambridge Professor Peter Wadhams. Climate Code Red summarizes the science, saying the sea-ice is "in a 'death spiral' and likely to be gone in summer within a few years" ... "The sea-ice volume is now down to just one-fifth of what it was in 1979", and paints a newly emerging, rapidly worsening climate picture, urging climate scientists to sound the alarm on new data showing a world on the brink of dramatic tipping points, far sooner than anyone anticipated

Summer ice in the Arctic to disappear

Several measures of Arctic ice cover have hit record lows. Melting usually continues into September, so this year’s minimum should be below the 2007 record. The rate of melting far exceeds that predicted by most models. Predictions of when the Arctic might be entirely ice-free at the summer minimum are being brought sharply forwards.

Can an activist be a good scientist?

NASA's James Hansen has been called the "godfather" of climate warming, largely because of his long record of major publications on the topic. He is also a determined climate activist, protesting, blockading, and demanding (PDF) that immediate action be taken to deal effectively with the issue, while using his science to advance his case. Recently, he and 2 colleagues effectively contradicted the widespread view that individual extreme weather events cannot be directly linked with observed climate warming, using extreme high temperatures as an example. [additional earlier and new (PDF) information]. (See previous (PDF) related work by others.) Several climate experts have attacked Hansen's activism and his science (PDF). Does his activism make James Hansen a bad scientist? (Related previous posts here and here, now peer-reviewed and published.)

Could global warming become an election issue? After the extreme weather last year and the likelihood that 2012 will reach a record high global temperature (which it almost has), it's possible that hot weather could become politically noticeable. Most Americans say they believe temperatures around the world are going up and that weather patterns have become more unstable in the past few years, according to this poll (and this other poll and this other poll.) Obama has said that climate change and the money being thrown into the denial of science is one of the most important issues in the coming campaign discussion. but Romney doesn't know.

A new way of accounting for ecological costs?

Social Credit is a movement that takes a different view of economic expansion. Mostly it focuses on how value is created and what happens to the excess value. Proponents can be very aggressive or very mellow but a key part of their philosophy is that we must recognize the value we've inherited from the past. In other words, we don't start our lives with an empty ledger but have inherited many physical and intellectual gifts from previous generations. Recently I began wondering whether we shouldn't look at the other side of the ledger, particularly when it comes to ecological impacts - i.e., the messes we inherit. It turns out that in the early 90s, some social credit economists were writing about this and were even talking about climate change as something that needed to be added to the equation. Is this an idea whose time has finally come?

Oh, the weather outside is frightful...and it might be a good idea to get used to it

"From extreme drought, heat waves and floods to unprecedented tornado outbreaks, hurricanes, wildfires and winter storms, a record 12 weather and climate disasters in 2011 each caused $1 billion or more in damages". The US National Weather service has put together a great online exhibit of what was a whirlwind (*ahem*) year for extreme weather events. The exhibit has lots of videos and photographs of these events, such as satellite imagery of the Grounhog Day Blizzard from back in February and a picture of a car damaged by a tornado in Ft.

sorry we torched the world and now you have to live like saints and suffer

Now the future is a kind of attenuating peninsula; as we move out on it, one side drops off to catastrophe; the other side, nowhere near as steep, moves down into various kinds of utopian futures. In other words, we have come to a moment of utopia or catastrophe; there is no middle ground, mediocrity will no longer succeed. So utopia is no longer a nice idea, but a survival necessity.

If global warming is not slowed from its current pace, by midcentury 3σ events will be the new norm and 5σ events will be common.

The controversy extends beyond the currently poor safety record for delivering oil between the two countries, and beyond the environmental and health consequences of the oil extraction process for locals and the cost of climate changes it will contribute to, all the way to legal wrangling between Canadian media and Saudi Arabia over the "death panels"-like term "ethical oil", based upon a conservative group's advertising that argues that the purchase of Canadian-sourced oil is a morally superior act, because of oppression of women and human rights violations by the Saudi kingdom.
