fossil fuels
David Appell at Quark Soup draws our attention (via Stoat) to a graph in the recent America's Climate Choices report from the NAS/NRC. If the forecasts on which the authors rely come to pass, it's going to take almost a couple of decades for U.S. energy-related CO2 emissions to return to post-recession levels. Sounds like good news.
Two years ago, Lester Brown at the Earth Policy Institute wrote of a watershed moment, and while it looks like he was a bit too enthusiastic -- long-term, carbon emissions still rise -- he might have been on to something.
The United States has ended a century of…
What if we could avoid hundreds of thousand of deaths, billions of dollars in crop losses and trillions of dollars in healthcare expenditures simply by spreading off-the-shelf technology and industrialized-world regulations to developing nations? Oh, and along the way, we'd mitigate a fair bit of global warming. Sounds like a plan?
I'd say such a plan would be worth considering. Such a plan is outlined by a team led by NASA's Drew Shindell in Nature Climate Change, which has generously made their paper, "Climate, health, agricultural and economic impacts of tighter vehicle-emission standards…
Proponents of shale gas extraction are not particularly pleased with the attention drawn this week to a new study in Climatic Change that found widespread development of Marcellus natural gas may actually accelerate climate change rather than slow it down. Unfortunately for them, their primary argument rests on a lack of hard data on 1) the actual greenhouse-warming potential of methane; and 2) how much methane finds its way into the atmosphere during drilling and transmission of natural gas. You can find a good summary of the defense's case at something called the Marcellus Shale Coalition.…
It was in Bill McKibben's first, and arguably best, book, The End of Nature, that I first came across the challenge posed by fugitive emissions. Back then -- just 20-some years ago -- natural gas was touted as a cleaner alternative to coal and oil because the combustion of its primary constituent, methane, results in markedly fewer CO2 emissions than other fossil fuels.
That argument is being made even more forcefully now. Everyone and his or her dog is touting the advantage of converting coal mines and car engines to natural gas as a way to mitigate global warming, as well as reduce oil…
See that black box over on the left-hand side of this blog? The one with the numbers counting down? That's a little widget I assembled by rejigging one from trillionthtonne.org. The basic idea is that, if our climate can be expected to suffer severe disruption at a certain amount of global warming due to a certain amount of carbon emissions (since the beginning of the fossil-fuel era around 1850), then our best strategy should be to limit the cumulative carbon emissions to somewhere below that level, in this case 1 trillion tonnes of carbon.
But there's plenty of uncertainty surrounding the…
No one is more surprised than I to see something worthwhile reading in The Daily, Rupert Murdoch's iPad magazine. You might even be forgiven for suspecting an April Fool. But there it is. It's an editorial by Shikha Dalmia, a senior policy analyst at frequently misnamed Reason Foundation, exploring the fundamental problem with nuclear power. Dalmia's indictment goes far beyond the nuclear industry, though. Intended or not, it strikes at the heart of the economic philosophy that dominates pretty much the entire planet To wit:
The liability cap effectively privatizes the profits of nuclear and…
At one end of the hyperbole scale we have Helen "If you love this planet" Caldicott, who raises the specter of "cancer and genetic diseases" if things get any worse at the growing list of nuclear power reactors crippled or destroyed by last week's earthquake in Japan. At the other we have Republican congressman Mitch McConnell, who argues that we shouldn't abandon nuclear power, especially "right after a major environmental catastrophe."
In between the pundits and genuine experts are pointing out that the mining, processing, and burning of fossil fuels kill hundreds or even thousands of times…
We all know we need to get off fossil fuels and replace them with carbon-neutral alternatives. The question is not IF we should choose this path, but how best to get where we need to go. There are those who, fairly enough, worry that those clean renewables aren't up to the job. This is a critical question, because if renewables can't fill the void, then we are left with no option but to build more nuclear reactors, with all the myriad problems that accompany them, most notably price, which is forever rising. So much money is at stake that we need to sort out this question, soon.
It all boils…
Last week it was the abuse of a 140-character context-free nano-report on an hour-long discussion on the challenges of communicating science. This week it's the credulous coverage of a 50-page report on climate change. Seems that no matter the length of the material at hand, there are plenty of people eager to jump to conclusions without having the decency to stop and think first.
At least there was no slander this time. But damage has been done to the credibility of climatology, thanks to that old adage, a little knowledge is a dangerous thing. Now claims of unwarranted alarms have that much…
Just in case you need a refresher:
It continues here. Meanwhile, the Onion sums it up nicely:
"Climate change is real, and we are killing our planet more every day," said climatologist Helen Marcus, who has made similar statements in interviews in 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, and 2010. "We need to make a serious effort to stop it, or, you know, we'll all die. There really isn't much else to say."
For 2011, I am going to try to implement Oscar Wilde's advice:
"If you want to tell people the truth, make them laugh, otherwise…
You've no doubt come across this before, but it's worth repeating whenever someone does a story on the American auto fleet's fuel economy:
The New York Times reports that "the average fuel economy in 2009 model cars, vans, pickups and S.U.V.'s was 22.4 miles per gallon -- an increase of 7 percent, or 1.4 miles per gallon, over 2008 figures." Environmentalists, we are told, hailed the news.
Which means the fleet average is now just 2.6 mpg shy of what the Ford Model T achieved 102 years ago. The good news is that embarrassing record is for lack of trying. If we're lucky, the Volt and Leaf are…
John Perlin has written an interesting Miller-McCune article about how the Pentagon has come to understand some of the problems associated with powering Iraq and Afghanistan operations - and how they're now reducing operations' energy consumption and embracing solar power.
Perlin describes the experience of Lt. Gen. Richard Zilmer, who assumed command of the coalition forces in Iraq's Al Anbar province in 2006 and soon realized that his command's reliance on trucking in liquid fossil fossil fules was contributing to casualties. In today's conflicts, Marine combat brigade uses half a million…
The invaluable pseudonymous Tamino has a brilliant explanation of the causes of the "global cooling" trend in the mid-20th century. There's nothing new, except the clarity of the writing. So if you've ever been stumped by a skeptic who suggests that anthropogenic climate change theorists can't explain why the planet cooled for the three decades following the Second World War, bookmark this post.
Just a tease:
... the 1940-1975 time period experienced anthropogenic global cooling. This cooling was from the same root cause as volcanic cooling, namely aerosols (mostly sulfate aerosols) in the…
What happened at Three Mile Island in 1979 led to a new regulatory environment that increased the costs of building and running nuclear power reactors in the U.S. The environment was so hostile to the industry that no new reactors have been ordered since then. There are several in the planning stages, but none have been approved. The question now being debated among energy analysts is whether or not what's going on in the Gulf of Mexico at the moment will lead to similar challenges for the oil industry.
Of particular interest is the precedent set this week when BP agreed to pony up $20…
The most intelligent thing I've read so far about Obama's speech Tuesday night, the one that included not a single mention of climate change, comes from Ezra Klein at the Washington Post. He's talking about the assumption that fear doesn't motivation people, only inspiration does.
But that strikes me as depressing evidence of how unlikely we are to succeed. I simply don't believe you could've passed health care if you couldn't have talked about covering the uninsured, and I don't think stimulus would've worked without the spur of the unemployed. It's not that people wanted to hear about…
The Boston Globe has assembled 40 outstanding photographs of what's happening in the Gulf. Click on the shot below to see the rest:
Most of the alarmism generated by climate predictions deals with sea level rise, drought, and biodiversity loss. But what happens to waterfront property, farms and polar bears could be the least of our worries if temperatures rise much more than a few degrees. A new paper in PNAS, "An adaptability limit to climate change due to heat stress," paints a much more dire future for much of the larger mammals on the planet, including humans.
In the paper, Steven Sherwood of the University of New South Wales and Matthew Huber of Purdue University try to estimate how warm the Earth can get before…
The estimates of the just how much oil is spewing into the Gulf of Mexico from BP's Deepwater Horizon rig keep rising. The latest guess -- and it is just a guess -- is something like 210,000 gallons a day. It is almost certainly going to eclipse the Exxon Valdez catastrophe by the time things are brought under control. Who knows how much damage has been done to the Gulf Coast ecology and economy? But could it be that we're lucky this happened where and when it did, instead of a few years down the road in an even more difficult spot, say the Arctic Ocean?
Canada has long been interested in…
This is a thin section from some Colorado shale. It's part of the Green River Formation, which is a series of rocks laid down about fifty million years ago when the West was wet. The shales come from a set of lakes that occupied part of what is now Colorado, Wyoming, and Utah.
If you look carefully - behind the white blotches, where the contrast is too blown out to say much but they might be grains of sand or bits of shell that fell into the lake where this was forming - you'll see that the shale was deposited in alternating layers of dark stuff and light stuff. The dark stuff is organic…
