Methane: There ought to be a law

Regulators in Minnesota made the bone headed decision to approve the building of a new natural gas plant on the Minnesota-Wisconsin border near Duluth. They are idiots. There is no calculation that requires or even strongly suggests that this is a good idea. It has already been determined that this plant is not necessary. This is just the petroleum industry getting its way. I call for an investigation of the three (out of five) individuals who voted for this lame brained scheme. I want to know what stocks they own, and I want to see their bank records for the last, and next, five years.

Meanwhile, I call on Legislators in Minnesota to pass a law stating that we can not add any more fossil fuel sources into our energy mix, in utilities within or overlapping with the state of Minnesota. We need that bill passed during the next legislative session, to stop this plant and similar ideas in the fiture.

The building of this particular natural gas plant is not inevitable. It still has to be approved on the Wisconsin side of the border. From NPR:

If Wisconsin regulators approve the plan, the new power plant would produce at least 525 megawatts of electricity. Minnesota Power and its ratepayers would be on the hook for half the $700 million cost.

Minnesota Power covers roughly a third of the state, mostly in the northeastern quadrant of Minnesota, from Little Falls in the south to International Falls in the north and over to Duluth and up to Canada. Its customers include large taconite mines and power plants.

PUC regulators heard final arguments in the case earlier this month. Commissioners also decided Monday that the plan did not need to undergo additional environmental analysis, a decision that paved the way for its approval vote.

Methane is not a bridge fuel. It is a fossil fuel, and a greenhouse gas.

Debunking climate change denialism

Climate change science denialism has pretty much run its course. We’ve been experiencing a large number of climate change related events (see this list for a brief summary) lately. It may well be that the number per year of such alarming events will go down and up over time. It may be that we will forget that some of them are happening because we grow used to them. But they are happening at a larger rate than just a few years ago, the years are getting warmer and warmer, and the effects predicted by the science have been manifest as predicted, but for on thing: They are happening sooner, faster, and worse than predicted in many cases.

But even tough climate change science denialism is now being moved aside (rightfully so) it is still out there an you may encounter it. Many of the active denialists can’t really back down because they are so invested in the denialism that doing so would require that they admit that the effects of denialism on policy have been deadly. Science denialists do, in fact, kill people indirectly whether it be in the form of anti-vax denialism, climate change science denialism or some other form.

There is a web site that specializes in addressing the various questions denialists raise in order to cast doubt on the real science. We are no longer at the point where pro science people need to have the answers ready when the denialsts show up, because that just gives them more credit than they deserve. Rather, the appropriate response is to point them to this site: Skeptical Science

What you need to know about Frankenstorm Hurricane Sandy

If you are in the path…the thousand mile wide path…of Hurricane Sandy, a.k.a. Frankenstorm, then you should make sure you know what the storm could do in relationship to where you are. If you are in or near an area with mountains, look for very serious flash flooding. The winds will be strong everywhere. If you are near the coast, be aware that the highest storm surges seen in years are expected in many areas. At the same time, it is important for those of us writing or talking about this storm to be realistic and careful in making predictions. This is becasue every case of dire prediction that does not materialize is a morsel of ignorance that will be served up later by climate change denialists who profit from confusing the general public about the connection between climate change and storminess. Here, I’d like to do the following: Give a brief overview of what Sandy is all about; address the question “Can you attribute Sandy or any other large storm to Global Warming?”; and tell you about some recent research related to that question. I’ll also throw in a little bit of historical background by way of discussing a nightmare scenario that actually didn’t happen.

Nightmare Storms

First the nightmare scenario. Years ago, my first long distance trip anywhere not involving aircraft was a road trip from Albany, NY to the Southeast, the Southwest, California, and back. This was in the 1970s, and it took months. On the way out, I encountered a storm in Texas that stranded me there, in Big Spring, for several days. The state was covered with a layer of ice, and there was no way to handle it. Months later, on the way back, I drove through the aftermath of that storm and a very long time after the storm had passed though, there were still wrecked semis littering Routes 30 and 40.

I did not live in Boston at the time, but that was the year Boston was hit with a very severe storm, was part of the same system that iced the Lone Star State. In Boston, so much snow fell during rush hour that the cars on the major beltways that go around the urban core were trapped in situ. People died of exposure in their own cars, or en route on foot to “safety” from more remote parts of the road. Hundreds of homes and cabins along the coast were destroyed.

That was one of several storms leading to changes in zoning and regulation along the north Atlantic coast in the US which led to no more building and in some cases the aggressive removal of structures on the open coast or barrier islands. A couple of years later I did move to the coast, and spent a fair amount of time on the shores of Cape Cod, Plumb Island and elsewhere. As an archaeologist, I fully enjoyed encountering the remains of homes or small settlements. There would be nothing standing, but the remains of houses and their contents would be poking up here and there. It was always interesting to try to figure out based on the position and location of the largest bits where the home may have originally sat, and based on the degree of deterioration of the remains, which of the recent storms had destroyed the home or cabin.

One of the great historical events one learns of while working, in historic preservation and archaeology in New York and New England is the Great Storm of 38. The big storm in the 70s happened 35 years ago, and 35 years or so before that a storm came up the Atlantic, crossed Long Island, slammed into Rhode Island and Southeast Massachusetts, and generally made a mess of the interior, destroying lots of homes and killing lots of people. We now think it was a hurricane, but the people of New England at the time, including fisherfolk who’s lives and livelihood depended on the sea and on knowledge of the weather, had not even heard of a “Hurricane” before. Surely, hurricanes had come up the coast before, but with such infrequency that they were not a named phenomenon. Just another (big) storm. Years after the Storm of ’38, when I was busy climbing all the High Peaks in the Adirondack Mountains, I was often challenged by “slides” and blowdowns caused by that storm. Anyone who knows the ADK’s of the 1960s and 1970s or earlier knows of the big slides on Giant and the other steep sloped mountains, and the blowdowns on the Dix range. Those features of hiking and climbing are mostly courtesy of the big storm of ’38.

Here’s the thing. Imagine that a storm like Sandy came along in either of two years; 70 years ago or 35 years ago. Sandy is much larger and contains much more energy than the ’38 storm, or for that matter, of any known storm of the North Atlantic (we’ll get to that below). If Sandy hit the region in the 1930s, it would have been without warning, and it would have been prior to the reconstruction of seawalls and the development of flood mitigation measures inland that have happened in recent decades. Sandy, in ’38, would kill tens of thousands and destroy thousands of structures. That would be an average Sandy, a Sandy not being as bad as the most dire predictions we are considering today as the storm begins to take a grip on the eastern seaboard.

A Sandy of 35 years ago would have been predicted. The ability to see hurricanes coming was in place, but not as well developed as it is today. We would have seen Sandy coming, but her massiveness and extent, and her exact trajectory, would probably have been unknown. But at least there would be warning. Many of the seawalls and flood mitigation systems would have been in place, but the overbuilding on barrier islands and other vulnerable coastal regions would have been at or near a peak. With evacuations, Sandy would not kill 10s of thousands… probably only hundreds. But the number of buildings destroyed would be unthinkable. Most of those buildings are now gone or shored up. A Sandy in 1975 would have left some very interesting coastal archaeology for me to have observed during my trips to the shore in the 1980s. Very interesting indeed.

Do you remember the October storm of 1991, a.k.a., the Halloween Nor’easter a.k.a. The Perfect Storm? I do. I was living in Somerville, Ma. After the storm raged for hours and finally calmed down a bit I went out for a walk. Power lines and large tree fragments littered the landscape. There would be no driving for a day or two in many neighborhoods. I was able to get out the next day, and I drove right up to Cape Anne, near Gloucester (Bass Point to be exact), where the Andrea Gail had sailed from never to return. I had not heard about the Andrea Gail yet but I went down to Glouscter to see the waves.

Is Sandy Caused By Global Warming?

ResearchBlogging.orgI remember parking the car along side the road, and climbing over a granite riprap structure to get to the shore. I stood on that high point, and from there could see a few dozen people milling around at a much lower elevation, taking pictures of the waves that were rolling in. I did a rough calculation. How far inland would a wave wash if it was double the size of those I could see now? Double and triple size waves … rogue waves … would not be unlikely after a storm like this. When I realized that my shoes would probably get wet, and all the people down at a lower elevation would probably get washed away, if that happened, I went back to the car and drove to the clam shack in Ipswich for lunch. Later that day, I hear, the authorities cleared the beaches. The waves I was watching were 10 meters if they were a centimeter. Indeed, 30 meter waves were recorded asea in Nova Scotia, and high waves killed a couple of looky-loos on Staten Island. That storm was one of several that hit New England since the big storm of the 1970s. Everybody who lives in the region knows that the storms have become more common and more severe, and probably lager, wider, in extent.

But is there any evidence to support that?

Well, yes, actually, there is. Here’s the abstract from a recent paper:

Detection and attribution of past changes in cyclone activity are hampered by biased cyclone records due to changes in observational capabilities. Here we construct an independent record of Atlantic tropical cyclone activity on the basis of storm surge statistics from tide gauges. We demonstrate that the major events in our surge index record can be attributed to landfalling tropical cyclones; these events also correspond with the most economically damaging Atlantic cyclones. We find that warm years in general were more active in all cyclone size ranges than cold years. The largest cyclones are most affected by warmer conditions and we detect a statistically significant trend in the frequency of large surge events (roughly corresponding to tropical storm size) since 1923. In particular, we estimate that Katrina-magnitude events have been twice as frequent in warm years compared with cold years (P < 0.02).

So, over the years, it gets warmer and colder and in warmer years there is more stormosity, as it were. Warm=storm. At the same time, the amount of warm (number of warm years and how warm they are) has been going up. More storms over time, just as any honest Salt can tell you. Here’s a nice graph from the same paper:

(A) Average surge index over the cyclone season. (B) Observed fre- quency of surge events with surge index greater than 10 units/y (surge index > 10 units) and linear trend (black). (C) Accumulated cyclone energy for US landfalling storms. (D) Annual average global mean surface temperature anomaly from GISTEMP (23), shaded to show warmer and colder than median temperatures. Thick lines in A, B, and C are 5-y moving averages. Inset in A shows locations of the six tide gauges used in the construction of the surge index.

Now, here is what you’ll hear a lot of people say. People will tell you that “you can’t attribute any given storm to global warming.” There is a certain way in which that is true, but there is also a certain way in which it is wrong, and the importance of recognizing the relationship between global warming and storminess is now so important that the former has become little more than a pedantic nuisance and we’d better start focusing on the latter.

One of the reasons why this statement is true is a little unfair to those saying it, or for that matter to the phrase itself, and is extrinsic to the logic of the statement itself, yet is still a valid reason. Here’s the thing. People often say “Well, you can’t attribute a given weather event to climate change” or, more importantly, people often hear that said, and then in their brains a disconnect between climate and weather is established or verified. In other words, people use that phrase to give themselves permission to not worry about climate change vis-a-vis storminess. One might argue that it does not matter that people use this phrase incorrectly, it is still true. But it does matter a great deal because the bigger, overwhelmingly important issue is the lack of social and political will to tackle global warming as a problem. Phrases that are a) technically true but b) miss the point and c) contribute to the end of civilization do not deserve our protection. Just. Stop. Saying. It.

The other way to look at it, the way in which we might fairly and logically say that warming weather can be said to be the cause of a particular storm, is best viewed in a thought experiment first. Suppose there were no Nor’easters, like Sandy. Suppose hurricanes were never, ever known to travel north of Georgia and were not that common. Now, imagine that we warm the world up a bit and this warming causes Nor’easters to start to form, and it causes hurricanes to start heading farther north, and then, some of those Nor’easter low pressure systems combine with some of those hurricanes and cause Frankenstorms.

Those Frankenstorms were caused by global warming.

In a world in which storms generally are more severe, more common, bigger, go farther north, or do some other nasty trick (any subset of this list may pertain, it is not necessary that all are true), one might well ask the question: “Is there any way to say that a given North Atlantic Frankenstorm emerged from the sea and the atmosphere without any of the added energy of global warming contributing to the severity, size, and northerly track of that storm?” And the answer is, “No, of course not, don’t be a bonehead.”

It is often said that storms are going to happen anyway, but global warming ramps up the probability, which is akin to saying that there is always going to be variation in temperature or some other weather related factor but global warming raises the baseline. That’s true. But the corollary to that is NOT that you can’t link climate change to a given storm. All storms are weather, all weather is the immediate manifestation of climate, climate change is about climate. Before we started talking about global warming, storms were caused by … things. Climate things. Did we ever say, back in the 1950s when a hurricane hit Florida, “Oh, ya, that was some hurricane, but the thing is, you can’t really attribute a given hurricane to the Intertropical Convergence Zone’s relationship to warm Mid Atlantic currents. The former is a weather event and the latter is a climate system.” Why did we not ever say that? Because it would have been irrelevant, even dumb.

The truth is, we experience more Atlantic severe storms because of global warming, though we are still working out the details of which features of which kinds of storms are affected most. Beyond this, it may well also be possible that something I hinted at above is true: We may be experiencing kinds of storms today that were very rare in recent centuries, because of global warming.

In any event, there’s more. From the paper:

We detect a statistically significant increasing trend in the number of moderately large surge index events since 1923. We estimate that warm years have been associated with twice as many Katrina-magnitude events compared with cold years in the global average surface temperature record.

I recommend this recent piece by Neela Banerjee on the link between climate and weahter, as well as Storms of my Grandchildren by James Hansen.

What is Sandy Going To Do?

Jeff Masters, at The Wunderblog, has an excellent post on Sandy, what’s going on now, and what might happen. It is here. Keep in mind that by the time you click through to that he may have put up a newer post, so check for that. Meantime, here’s a few salient items you may want to know about:

  • Sandy, the storm, is of record size, larger than any storm ever seen before. It is over 1,000 miles wide, with 12 foot seas covering that entire area. There’s been a couple of storms with this or that dimension exceeding Sandy, but in some other way they fell short. Sandy wins.
  • You already know about the whole “landfall” problem with storms, so I won’t go into this here. The thing is, even while Sandy’s worst rains and winds are no where near the coast, she is putting up storm surges already, and roads are being washed away as we speak with days of storminess ahead of us. (This is the thing about “Nor’easters… they go on for much longer than mere hurricanes!)
  • Sandy will generate modest storm surges from South Carolina to Canada, with severe storm surges from Delaware to Massachusetts.
    The storm surge in New York City may be higher than ever seen before, and has about a 50-50 chance of flooding the subway system in the vicinity of the Battery. That has never happened before.
  • Tropical force winds will batter 1000 miles of coast on Monday and Tuesday, with hurricane force winds covering a 500 mile section of coast.
  • Remember all the flooding associated with Irene in 2011? Sandy will also cause major inland flooding, but not as much rain overall will fall, so overall the flooding will be less. However, what “less” means is relative. If you are in a hilly region of Pennsylvania or some other part of the northeast, you may well experience worse flooding with Sandy than you did with Irene. Or not. Overall, there will be less, but it will still be bad.
  • And yes, there will be snow. The usual places that get snow during Nor’easters are at risk. Any place with a high elevation or that is up north has a good chance of getting a few inches, or in some cases, a couple of feet.

Go to Jeff’s post for more details.

Indeed, the end of civilization is near! Ish!

I found it very interesting that the Maya recently came out to ask people to stop suggesting that somehow their cyclic calendar was going to cause the end of civilization, or the world, or whatever, at the end of the present year. This is a case of a traditional people well versed in their own indigenous technology (in this case, time tracking technology) noticing that the “civilized Western world” was making a major fool of itself, as usual, and then helpfully suggesting that certain people STFU. At the same time, we are doing it wrong for real and truly putting the future at risk, and not just with climate change, but how we address climate change. We are not making it part of the conversation in national elections, we are not making it part of our budget considerations, we are not making it part of our shovel-ready-stimulus activities. We are not even letting ourselves keep track of what we are ruining. The number of satellites that will be available to track storms like this will probably fall off in the near future to the extent that we won’t be able to do it. Talk about the end of civilization! Even if we didn’t simply screw up plans for putting up more satellites, we have this other growing problem with space junk. Our technology is warming our planet and at the same time blinding us, hampering our ability to manage the problem we are creating.

Stay safe.

HeartlandGate: Anti-Science Institute's Insider Reveals Secrets

This seems to be fairly big news. The Heartland Institute is a conservative and libertarian “think” tank that cut its teeth on denying the dangers of cigarette smoking back in the 1990s. These days the Heartland Institute seems to be focused on Anthropogenic Climate Change Denialism and Science Denialism in general.


A piece of one of the revealed documents suggesting that the Heartland Institute wants to “dissuade teachers from teaching science.”

Well, just a few hours ago, members of the climate change science, journalism, and blogging community received an interesting Valentine’s Day gift from someone who must be a Heartland Institute insider: The institute’s budget, fundraising plan, climate related strategy, and numerous other things. The story broke here on Desmog Blog.

Here’s the details:

Balancing Acts in Science

How do you know when alternative views are real alternatives, and thus should be considered in a “balanced view” vs. when those views are not any longer valid and should be ignored? This sounds like a hard thing to do but it is not as hard as you might think. I suggest two different approaches: “Tipping Points” and “Clues that Something is Wrong Here.”

CloudGate: Denialism Gets Dirty, Reputations Are At Stake

There has been a major dust-up in the climate denialist world. A study published in late July made false claims and was methodologically flawed, but still managed to get published in a peer reviewed journal. The Editor-in-Chief of that journal has resigned to symbolically take responsibility for the journal’s egregious error of publishing what is essentially a fake scientific paper, and to “protest against how the authors [and others] have much exaggerated the paper’s conclusions” taking to task the University of Alabama’s press office, Forbes, Fox News and others.

Minnesota AGW Denialist Jungbauer Disembowled by Respected News Anchor Don Shelby

I woke up this morning and the world was slightly different than it was the night before. Well, it probably always is a little different each day, but there are certain times when you notice this. I’m not talking about the bits of siding, roofing, and trees scattered about the landscape because of the very severe thunderstorm we had last night, although I suppose this is indirectly related.

If you are not a Minnesotan this will take some explanation:

Thinking of Global Warming

Amazingly enough, we (my family) are going to have to work very hard this year, as we did over the last two years, to get in even one or two good days of cross country skiing. And we live in the middle of Minnesota. This is partly because a good bit of the precip that falls on us these days is actually rain and not snow.

But this is of course a very selfish concern, to the extent that this change is related to human-induced global warming (which I’m betting on). And this reminds me of how often I get the question from students and others, “why worry about global warming … what’s wrong with a little warm weather anyway.”

For one thing I think it is safe to say that the “controversy” is over. No one is seriously questioning that there has been warming, that we are in a warming trend, and that this trend is caused primarily by human release of otherwise trapped (mainly fossil) carbon into the atmosphere. Nice to know that the Yahoos are pretty much silenced by the facts on that one…

Still, the question arises, “why is this important” … even in places where you might not expect it, like this discussion on the geology of the grand canyon: Another Timeline

There are a lot of resources available on this issue, but here is a short version of my two cents:
