• Independent statisticians reject recent global cooling claims in blind analysis

• IEA: climate treaty necessary to keep energy prices low

Climate disruption deniers have been claiming for years now that the global temperature has been cooling down, even though the temperature data clearly shows that it isn’t. Scientists and statisticians have pointed out that, mathematically speaking, the recent reduced warming trend is well within the noise, or put another way, it’s weather, not climate.

A new report by the Associated Press reveals what many of us knew already – the denier’s claims don’t hold water, statistically speaking. The report is intriguing because the AP provided their data to four independent statisticians without telling them what it was, and all four found that the slower warming of the past decade was statistically insignificant with respect to the actual data.

In the introduction to Last Chance – Preserving Life on Earth, author Larry J. Schweiger, the CEO of the National Wildlife Federation, comes right out and says that he’s not trying to change minds with this book. Instead, it’s his hope that the book will motivate millions of people to transform their concerns over global warming into activism.

There are three sections to the book that can be summarized as follows. First, the latest science says that disruptions due to climate change will be worse and happen faster than the best estimates of even a couple of years ago. Second, there are a few global ecosystems that are more sensitive than even average, and there are people who don’t want you to know that and who actively work to keep you ignorant of the facts. And third, there are a few things we can do to help ourselves and the Earth.

When you look at the ice core record, there’s a significant amount of correlation between sea level rise and the amount of carbon dioxide (CO₂) in the air at the time. But the ice core record goes back less than a million years. A study published a couple of weeks ago in the journal Science measured proxy data for CO₂ concentration in the ocean and compared that data to other data on the stability of ice sheets. The authors discovered that there is strong correlation between the two going back at least 20 million years.

One of the challenges that the authors had was the fact that few available previous studies didn’t show correlation between the amount of CO₂ in the air and the global climate prior to the start of ice core data. The authors hypothesized that this was a problem with the other datasets and developed a set of tests to check their hypothesis. Full Story »

Most people view climate disruption as a horror that we and the generations before us are about to visit upon our children and grandchildren. And there’s a great deal of truth to this view. The “civilization will end if we don’t stop global warming” approach is ultimately based on negativity, specifically on fear. But as bad as the future could be, fear isn’t the only way to approach talking about climate disruption. There are positive images and positive messages that can be pulled out of climate disruption as well. It is possible to make addressing climate disruption seem fun, even sexy.

Here are two very different, but simultaneously very effective, examples of climate messaging. First, the negative. Full Story »

Imagine that in a few years you wake up to news reports on the radio that your town is under a flash flood watch. The ground has been so baked by the recent drought that water can’t soak in, and so the pounding rain is just flowing off into streams and filling low-lying areas.

What’s worse is you’ve got a pediatrician appointment today for both of your kids – their asthma is acting up and the drugs aren’t working as well as they should be. Furthermore, your son is still recovering from a case of malaria he picked up, probably from a mosquito bite he got during the pee wee football game by the reservoir a couple of months ago. At least the rains will damp down on your environmental allergies some today. Better rain, even flooding, than the dust storm that blew through the area a couple of weeks ago. That caused several major pileups and fouled up ventilation so bad that some of the buildings downtown are still closed..

As you pull together breakfast for the family, there’s no milk because it’s too expensive. Full Story »

I have no doubt that the climate is changing, nor that it will continue to change.  It seems reasonably well established that  the Earth has gone through extreme climate swings in the past; on the basis of that i predict that it will do so again. Maybe humans are not responsible for climate change, and the planet would be warming in any case as it sheds the final remnants of the last ice age. Maybe it is entirely our fault. The truth usually falls between the two extremes. I do not believe that humans have the power to destroy the Earth or life. Suggesting that we do strikes me as the height of egocentricity: both preceded us by unimaginable lengths of time and will survive us for just as long. We do, however, have the power to destroy ourselves and most of the forms of life we know.

Is the Earth’s climate approaching a critical transition, aka a “tipping point,” beyond which major and largely unpredictable climate changes are guaranteed to occur? At this point, scientists do not know the answer to that question. A study published in the journal Nature aims to explain the mathematics of critical transitions beyond just the Earth’s climate and in the process, determine if there are early-warning signals that indicate when a complex system is about to undergo a critical transition.

According to the paper, every complex system, whether it be climate, asthma attacks and epileptic seizures, or systemic crashes in financial markets, exhibits the same basic precursor signs of a tipping point, at least mathematically speaking. Full Story »

The fate of the earth could end up determined by which tipping point is reached first: a physical shift that ushers in abrupt climate change with catastrophic consequences, or a social one, in which public attitudes rapidly coalesce around a mandate to address climate change. Or, neither could materialize, at least not imminently.

Al Gore believes the U.S. is on the brink of a political tipping point on the climate issue. Speaking to the Society of Environmental Journalists annual conference in Madison, Wisc., last Friday, the former vice president said, “The potential for change can build up without noticeable effect until it reaches a critical mass. I think that we are very close to that tipping point.” Full Story »

Nature News reported last week that vulcanologists have concluded that climate disruption will increase the number of volcanic eruptions. According to the article, the reason is that climate disruption is expected to reduce the amount of ice present atop volcanoes and thus reduce the amount of material keeping volcanoes from erupting.

Scientists, mariners, and weather hobbyists started directly measuring temperature with thermometers globally in the late 1800s. When modern climatologists want temperature data farther back in time than those first global measurements, they have to use things called “proxies.” A proxy for temperature is something that, when calibrated properly, indirectly measures temperature. The most common proxies that are used as temperature stand-ins tend to be tree rings, the amount of an oxygen isotope in ice cores, and coral growth rings.

There are a couple of problems with proxies, however. The first problem is that scientists have to develop an appropriate and accurate calibration method to convert the width of a tree ring to an average annual or summer temperature. The second problem is that a given proxy may well be influenced by other factors beyond temperature, and so calibrating the proxy becomes a difficult and potentially error-prone process. For example, tree rings are a proxy for both temperature and moisture, and so any climatologist who wants to extract just the temperature information needs to discover a way to independently estimate the effect of moisture changes on the tree ring before the effect of temperature on the tree ring can be accurately determined.

A new study published September 17^th as a letter in the journal Nature describes a new method to compensate for proxy changes due to elevation in the Greenland ice sheet (GIS) during the Holocene (the present geologic epoch, starting about 12,000 years ago). Full Story »

Last week, the Yale Project on Climate Change and the George Mason University Center for Climate Change Communications released their 2009 “Six America’s” study. The study finds that the U.S. population can be broadly broken up into six different categories that the study’s authors name as follows: Alarmed, Concerned, Cautious, Disengaged, Doubtful, and Dismissive. Here’s how the Executive Summary describes each of the six groups:

The Alarmed (18%) are fully convinced of the reality and seriousness of climate change and are already taking individual, consumer, and political action to address it. The Concerned (33%) – the largest of the six Americas – are also convinced that global warming is happening and a serious problem, but have not yet engaged the issue personally. Three other Americas – the Cautious (19%), the Disengaged (12%) and the Doubtful (11%) – represent different stages of understanding and acceptance of the problem, and none are actively involved. The final America – the Dismissive (7%) – are very sure it is not happening and are actively involved as opponents of a national effort to reduce greenhouse gas emissions.

On Wednesday, September 2, Duke Energy announced that they were withdrawing from membership in the American Coalition for Clean Coal Electricity (ACCCE), an industry group composed of utilities, mining companies, and other companies involved in the mining, transportation, and combustion of coal.

In response, the ACCCE issued a bland statement that didn’t even mention Duke by name. It says, in part:

ACCCE is a broad and diverse coalition, composed of more than 40 members, who are working to advance the public policy dialogue on critical issues relating to energy, environmental, and economic policies. From time to time, individual coalition members may have different perspectives with regard to important policy positions.

Earlier this week, the LATimes reported that the U.S. Chamber of Commerce (hereafter “the Chamber”) has petitioned the EPA to hold a trial-like hearing on the science of climate disruption. According to the article, officials for the Chamber want to make it “‘the Scopes monkey trial of the 21st century.’”

EPA officials interviewed for the LATimes article are dismissive of the Chamber’s petition, referring to it in the article as “frivolous” and a “waste of time.” However, given that the Chamber has threatened to take the EPA to federal court to force them to hold this trial-like hearing, it’s unlikely that the Chamber considers their petition “frivolous.” Full Story »

• ACCCE hired Bonner, but didn’t notify Congress of forgeries when they were discovered
• Cash for Clunkers doesn’t do much for climate
• National Academy of Sciences: we need independent GHG emission confirmation
• Climate disruption may, or may not, make disease worse

Before the House voted on the American Climate and Energy Security Act (ACES) earlier this year, someone hired Bonner & Associates (hereafter Bonner) to manufacture some grassroots opposition against ACES. At least one employee did so by forging letters from non-existent people to Representative Tom Perriello of Virginia. These letters were discovered, Bonner claims to have fired the employee, and a partner at Bonner apologized to the two minority groups from which the letters were supposedly sent. The apologies were, it’s fair to say, emphatically not accepted.

Since the Bonner story broke last Friday, there have been a lot of new information about who hired them, whether there were other Congresspeople who received forged letters, the legality or lack thereof, and an official response from a House committee with subpoena powers. Full Story »

In early 2008, the Oregon Institute of Science and Medicine (OISM) published their Petition Project, a list of names from people who all claimed to be scientists and who rejected the science behind the theory of anthropogenic (human-caused) global warming (AGW). This was an attempt to by the OISM to claim that there were far more scientists opposing AGW theory than there are supporting it. This so-called petition took on special importance coming after the release of the Intergovernmental Panel on Climate Change’s Fourth Assessment Report, and specifically the Working Group 1 (WG1) report on the science and attribution of climate change to human civilization.

The WG1 report was authored and reviewed by approximately 2000 scientists with varying expertise in climate and related fields, and so having a list of over 30,000 scientists that rejected the WG1’s conclusions was a powerful meme that AGW skeptics and deniers could use to cast doubt on the IPCC’s conclusions and, indirectly, on the entire theory of climate disruption. And in fact, this meme has become widespread in both legacy and new media today.

It is also completely false. Full Story »

• NE Pacific clouds observed to amplify warming

The question of whether clouds are a positive or a negative feedback is one of the biggest remaining questions in climate modeling. A new paper in the journal Science is another piece of evidence that clouds will amplify the effects of climate disruption instead of dampen it.

The authors of the study analyzed two unrelated observational methods and found that both showed a decrease in cloud cover over the Northeast (NE) Pacific as a result of climate changes in sea surface temperature (SST), sea level pressure (SLP), and two measurements of the troposphere (the lower atmosphere).

There are many people and organizations in the United States who oppose the American Climate and Energy Security Act (ACES), and many of them have mailed letters, written emails, and called their Representatives and Senators in an effort to convince their legislator to vote against ACES. Some of ACES’ opponents have deep enough pockets that they can afford to hire lobbying firms to lobby against the legislation, and did so. But someone took it much farther. Someone hired public relations and lobbying firm Bonner & Associates to mobilize the grassroots to contact their legislators, and according to a Charlottesville Daily Progress article, at least one Bonner employee forged letters from two minority groups in an effort to convince U.S. Rep. Tom Perriello of Virginia to vote against ACES. Full Story »

When studies look at the amount of greenhouse gases emitted by transportation, the focus is nearly always on the emissions created in fuel combustion – gasoline and diesel for cars and trucks, bunker fuels for maritime vessels, jet fuel for aircraft, and so on. One excellent example of this kind of study is the Getting There Greener study by the Union of Concerned Scientists (UCS). The UCS study shows that travel by bus emits the least carbon at all distances traveled and for one, two, or four travelers. Similarly, the study found that flying first class was almost always the worst option, with driving a typical SUV any appreciable distance coming in a close second.

But what most studies lack is a detailed analysis of the overall cradle-to-grave lifecycle of the transportation modes being compared. A new study by two University of California-Berkeley researchers has attempted to analyze the bulk of the lifecycle of multiple types of passenger vehicles, including fuel production, manufacturing and maintenance of the vehicles themselves, infrastructure construction and repair costs, all in addition to the basic fuel consumption. And the study also looks at three commonly regulated pollutants in addition to energy consumption and greenhouse gas (mostly carbon dioxide) emissions.

And the results are quite a bit different from purely fuel consumption-based analyses. Full Story »

“Fracking” is the slang term used for hydraulic fracturing, a process by which the gas industry injects a slurry of unknown composition into a gas well in order to break up the rock and release the natural gas contained within. At present, the EPA exempts fracking from regulation under the Safe Drinking Water Act (SDWA), but Representative Diana DeGette of Colorado has introduced legislation into the House (H.R.2766) to force the EPA to regulate fracking. In response, the gas industry has pushed back with studies that purport to show that regulation is both unnecessary and costly.

A new article by ProPublica, an “independent, non-profit newsroom that produces investigative journalism in the public interest,” shows that the exact same studies being used by industry to oppose fracking actually counter the industry’s own arguments. Full Story »
