Harper and climate change … spending

Filed under: Cancon, Environment, Government — Tags: , , , , — Nicholas @ 10:07

David Akin points out that all the major federal parties believe the same thing about climate change, except that the Tories are the ones who’ve been chucking around the money on climate change programs:

The simple fact of Canadian politics here is that, if you do not believe in climate change, there is no federal political party that shares your view. There almost was one in Alberta in its last provincial election but, boy, did that idea get shouted down.

But back to what [former environment minister Peter] Kent said to me in that interview:

“There is no question that since the Industrial Revolution there have been anthropogenic, man-made effects on our global climate. The argument continues in the scientific community how much is evolution and how much is man-made but there is certainly something we can do.”

So what is the something that the Harper government has been doing? Well, truth be told, the Harper Conservatives, like the Martin and Chretien Liberals before them, have not been doing very much. None of them, in fact, got the job done. Which might, come to think of it, be a good reason — if climate change is the only thing you’re voting on — to consider choosing the NDP or the Greens next time around. Not to say they’d actually get it done but it’s pretty clear the other two parties, while they talk a good game, just don’t have the political stomach for the job. Those New Democrats brought us universal health care. Maybe they can fix the environment, too.

Still, that doesn’t mean Conservatives aren’t prepared to spend hundreds of millions of dollars — billions even — on a problem they are accused of not admitting even exists. Take biofuels, for example. Early on, the Harper government got the idea that if corn- or plant-based ethanol displaced enough fossil fuels, we’d easily roll back greenhouse gas emissions. Apparently no one bothered to point out that there is serious doubt that corn-based ethanol is actually a lower-emission alternative to fossil fuels but why complicate things? Ethanol is a good, solid, job-creating green story!

In the long run, the subsidies and outright gifts of government money to green-ish sounding companies will likely be the only reminders of the great global warming panic of the last decade. Certainly little or no actual environmental improvements will be traced to the billions of dollars doled out to cronies under this government.

Statistical fail for political axe-grinding

Filed under: Environment, Media, Politics, USA — Tags: , , — Nicholas @ 11:29

Coyote Blog views with alarm a recent article in Rolling Stone which abuses statistics to make a point that apparently isn’t true:

What I want to delve into is the claim by the author that wildfires are increasing due to global warming, and only evil Republicans (who suck) could possibly deny this obvious trend […]

These are the 8 statements I can find to support an upward trend in fires. And you will note, I hope, that none of them include the most obvious data — what has the actual trend been in number of US wildfires and acres burned. Each of these is either a statement of opinion or a data point related to fire severity in a particular year, but none actually address the point at hand: are we getting more and larger fires?

Maybe the data does not exist. But in fact it does, and I will say there is absolutely no way, no way, the author has not seen the data. The reason it is not in this article is because it does not fit the “reporters” point of view so it is left out. Here is where the US government tracks fires by year, at the National Interagency Fire Center. To save you clicking through, here is the data as of this moment:

Wildfire averages 2004-2013

Well what do you know? The number of fires and the acres burned in 2013 are not some sort of record high — in fact they actually are the, respectively, lowest and second lowest numbers of the last 10 years. In fact, both the number of fires and the total acres burned are running a third below average.

The one thing this does not address is the size of fires. The author implies that there are more fires burning more acres, which we see is clearly wrong, but perhaps the fires are getting larger? Well, 2012 was indeed an outlier year in that fires were larger than average, but 2013 has returned to the trend which has actually been flat to down, again exactly opposite of the author’s contention (data below is just math from chart above)

Wildfires average acres per fire 2004-2013

In the rest of the post, I will briefly walk through his 8 statements highlighted above and show why they exhibit many of the classic fallacies in trying to assert a trend where none exists. In the postscript, I will address one other inconsistency from the article as to the cause of these fires which is a pretty hilarious of how to turn any data to supporting your hypothesis, even if it is unrelated.

Why wind and solar power can’t meet our needs

Filed under: Economics, Environment, Technology — Tags: , , , — Nicholas @ 10:32

Robert Bryce explains why — no matter how much we might want it to be so — alternate forms of energy like wind and solar power cannot cover our demands:

That 32 percent increase in global carbon dioxide emissions reflects the central tension in any discussion about cutting the use of coal, oil and natural gas: Developing countries — in particular, fast-growing economies such as Vietnam, China and India — simply cannot continue to grow if they limit the use of hydrocarbons. Those countries’ refusal to enact carbon taxes or other restrictions illustrates what Roger Pielke Jr., a professor of environmental studies at the University of Colorado, calls the “iron law of climate policy”: Whenever policies “focused on economic growth confront policies focused on emissions reduction, it is economic growth that will win out every time.”

Over the past 10 years, despite great public concern, carbon dioxide emissions have soared because some 2.6 billion people still live in dire energy poverty. More than 1.3 billion have no access to electricity at all.

Now to the second number: 1. That’s the power density of wind in watts per square meter. Power density is a measure of the energy flow that can be harnessed from a given area, volume or mass. Six different analyses of wind (one of them is my own) have all arrived at that same measurement.

Wind energy’s paltry power density means that enormous tracts of land must be set aside to make it viable. And that has spawned a backlash from rural and suburban landowners who don’t want 500-foot wind turbines near their homes. To cite just one recent example, in late July, some 2,000 protesters marched against the installation of more than 1,000 wind turbines in Ireland’s Midlands Region.

Consider how much land it would take for wind energy to replace the power the U.S. now gets from coal. In 2011, the U.S. had more than 300 billion watts of coal-fired capacity. Replacing that with wind would require placing turbines over about 116,000 square miles, an area about the size of Italy. And because of the noise wind turbines make — a problem that has been experienced from Australia to Ontario — no one could live there.

[…]

In 2012, the contribution from all of those sources amounted to about 4.8 million barrels of oil equivalent per day, or roughly one-half of a Saudi Arabia. Put another way, we get about 50 times as much energy from all other sources — coal, oil, natural gas, nuclear and hydropower — as we do from wind, solar, geothermal and biomass.

The IPCC’s new, more cautious tone

Filed under: Environment, Media, Science — Tags: , , , , — Nicholas @ 07:41

In The Spectator, a muted tone of “we told you so” about the upcoming IPCC report:

Next week, those who made dire predictions of ruinous climate change face their own inconvenient truth. The summary of the fifth assessment report by the Intergovernmental Panel on Climate Change (IPCC) will be published, showing that global temperatures are refusing to follow the path which was predicted for them by almost all climatic models. Since its first report in 1990, the IPCC has been predicting that global temperatures would be rising at an average of 0.2° Celsius per decade. Now, the IPCC acknowledges that there has been no statistically significant rise at all over the past 16 years.

It is difficult to over-emphasise the significance of this report. The IPCC is not simply a research body making reports and declarations which are merely absorbed into political debate. Its word has been taken as gospel, and its research has been used to justify all manner of schemes to make carbon-based energy more expensive while subsidising renewable energy.

The failure of its predictions undermines the certainties which have been placed upon the science of climate change. Previous IPCC reports — and much of the debate over how to react to them — have appeared to treat the Earth’s climate as if it were a domestic central heating system, with carbon emissions analogous to the dial on the thermostat: a small tweak here will result in a temperature rise of precisely 0.2°C and so on. What is clear from the new IPCC report is that the science is not nearly advanced enough to make useful predictions on the future rise of global temperatures. Perhaps it never will be.

Some climate scientists themselves, to give them credit, have admitted as much. Their papers now incorporate a degree of caution, as you would expect from genuine scientists. The problems arise when the non-scientists leap upon the climate change bandwagon and assume that anything marked ‘science’ must be the final word. As the chemist and novelist C.P. Snow once warned in his lecture about the ‘two cultures’, you end up in a situation where non-scientists use half-understood reports to silence debate — not realising that proper science welcomes refutation and is wary of the notion of absolute truths.

Hurricane and cyclone paths since 1842

Filed under: Americas, Environment, Pacific, Science — Tags: , , — Nicholas @ 08:59

Wired‘s MapLab has a lovely visualization of both hurricane and cyclone tracks starting with the earliest records in 1842:

Historical Hurricane and Cyclone paths since 1842

This map shows the paths of every hurricane and cyclone detected since 1842. Nearly 12,000 tropical cyclones have been tracked and recorded, and the National Oceanic and Atmospheric Administration keeps them all in a single database. Long-term datasets can be really interesting and scientifically valuable, and this one is undoubtedly both.

In the image above, you can clearly see that more storm tracks have overlapped in the western Pacific ocean and northern Indian ocean. This is largely because of the length of the typhoon season, which basically never stops in the warmer waters there.

The tracks of the earliest storms are based on mariner’s logs and storm records, collected from various countries, agencies and other sources. Reconciling data from these different entities was tough. Most international agencies had their own set of codes for cyclone intensity, and only recorded this information once per day. India was even using different wind thresholds to designate cyclone stages.

Fracking and the environment

Filed under: Environment, Media, Technology — Tags: , , , , — Nicholas @ 09:03

Matt Ridley debunks five common myths about environmental issues with fracking:

The movie Gasland showed a case of entirely natural gas contamination of water and the director knew it, but he still pretended it might have been caused by fracking. Ernest Moniz, the US Energy Secretary, said earlier this month: “I still have not seen any evidence of fracking per se contaminating groundwater.” Tens of thousands of wells drilled, two million fracking operations completed and not a single proven case of groundwater contamination. Not one. It may happen one day, of course, but there’s few industries that can claim a pollution record that good.

Next comes the claim that shale gas production results in more methane release to the atmosphere and hence could be as bad for climate change as coal. (Methane is a more powerful greenhouse gas than carbon dioxide, but stays in the atmosphere for a shorter time and its concentration is not currently rising fast.) This claim originated with a Cornell biology professor with an axe to grind. Study after study has refuted it. As a team from Massachusetts Institute of Technology put it: “It is incorrect to suggest that shale gas-related hydraulic fracturing has substantially altered the overall [greenhouse gas] intensity of natural gas production.”

Third comes the claim that fracking uses too much water. The Guardian carried a report this week implying that a town in Texas is running dry because of the water used for fracking. Yet in Texas 1% of water use is for fracking, in the United States as a whole 0.3% — less than is used by golf courses. If parts of Texas run out of water, blame farming, by far the biggest user.

Fourth, the ever-so-neutral BBC in a background briefing this week described fracking as releasing “hundreds of chemicals” into the rock. Out by an order of magnitude, Auntie. Fracking fluid is 99.51% water and sand. In the remaining 0.49% there are just 13 chemicals, all of which can be found in your kitchen, garage or bathroom: citric acid (lemon juice), hydrochloric acid (swimming pools), glutaraldehyde (disinfectant), guar (ice cream), dimethylformamide (plastics), isopropanol (deodorant), borate (hand soap); ammonium persulphate (hair dye); potassium chloride (intravenous drips), sodium carbonate (detergent), ethylene glycol (de-icer), ammonium bisulphite (cosmetics), petroleum distillate (cosmetics).

As for earthquakes, Durham University’s definitive survey of all induced earthquakes over many decades concluded that “almost all of the resultant seismic activity [from fracking] was on such a small scale that only geoscientists would be able to detect it” and that mining, geothermal activity or reservoir water storage causes more and bigger tremors.

“What LEED designers deliver is what most LEED building owners want – namely, green publicity, not energy savings”

Filed under: Business, Environment, Media, USA — Tags: , , , — Nicholas @ 10:24

A bit of LEED debunking at The New Republic:

When the Bank of America Tower opened in 2010, the press praised it as one of the world’s “most environmentally responsible high-rise office building[s].” It wasn’t just the waterless urinals, daylight dimming controls, and rainwater harvesting. And it wasn’t only the Leadership in Energy and Environmental Design (LEED) Platinum certification — the first ever for a skyscraper — and the $947,583 in incentives from the New York State Energy Research and Development Authority. It also had as a tenant the environmental movement’s biggest celebrity. The Bank of America Tower had Al Gore.

The former vice president wanted an office for his company, Generation Investment Management, that “represents the kind of innovation the firm is trying to advance,” his real-estate agent said at the time. The Bank of America Tower, a billion-dollar, 55-story crystal skyscraper on the northwest corner of Manhattan’s Bryant Park, seemed to fit the bill. It would be “the most sustainable in the country,” according to its developer Douglas Durst. At the Tower’s ribbon-cutting ceremony, Gore powwowed with Mayor Michael Bloomberg and praised the building as a model for fighting climate change. “I applaud the leadership of the mayor and all of those who helped make this possible,” he said.

Gore’s applause, however, was premature. According to data released by New York City last fall, the Bank of America Tower produces more greenhouse gases and uses more energy per square foot than any comparably sized office building in Manhattan. It uses more than twice as much energy per square foot as the 80-year-old Empire State Building. It also performs worse than the Goldman Sachs headquarters, maybe the most similar building in New York — and one with a lower LEED rating. It’s not just an embarrassment; it symbolizes a flaw at the heart of the effort to combat climate change.

[…]

“What LEED designers deliver is what most LEED building owners want — namely, green publicity, not energy savings,” John Scofield, a professor of physics at Oberlin, testified before the House last year.

Governments, nevertheless, have been happy to rely on LEED rather than design better metrics. Which is why New York’s release of energy data last fall was significant. It provided more public-energy data for a U.S. city than has ever existed. It found the worst-performing buildings use three to five times more energy per square foot than the best ones. It also found that, if the most energy-intensive large buildings were brought up to the current seventy-fifth percentile, the city’s total greenhouse gases could be reduced by 9 percent.

Investigators still don’t know what caused the explosion in Lac-Mégantic derailment

Filed under: Cancon, Environment, Railways — Tags: , — Nicholas @ 00:02

In the Globe and Mail, Jacquie McNish and Grant Robertson report on the ongoing investigations into the causes of the fatal explosion:

Federal officials probing the Lac-Mégantic disaster are testing the chemical composition of crude oil carried by the runaway train as they seek to answer the crucial question of what triggered the unusual and devastating explosion after the derailment.

[…]

Edward Burkhardt, chairman of Montreal, Maine & Atlantic Railway Inc., which operated the derailed train, said Canadian authorities have impounded the rail cars to take “a huge number of samples of oil.” He said the investigators and officials in the rail and oil industries “are asking how come there were explosions here. Crude does not blow up.”

People familiar with the investigation said the TSB is examining the composition of the oil that fuelled the explosion.

Industry sources said there are several possibilities. One is whether the crude, which came from the Bakken oil region of North Dakota, contained volatile chemicals. A possible scenario is that additives were intentionally combined with the crude oil to speed up the transfer of the syrupy oil, common for pipelines but rare in the rail industry. Another possibility is that the tanker cars had chemical contaminants from a previous shipment. Another question is whether the oil contained high levels of flammable hydrogen sulphide gas, which is sometimes present in Bakken oil.

[…]

Regulators in the United States say rail carriers are responsible for knowing what they are carrying, and that the shipper and the railway company are required to work out such details when the train is being loaded.

“The carriers have to know exactly what it is that they’re hauling at all times,” said Warren Flateau, a spokesman for the Federal Railway Association in Washington.

Mr. Burkhardt said MM&A received a detailed bill of lading from the U.S. oil services company, which he declined to identify, and no chemicals were identified as being present in the crude. The intermediary oil services company leased the rail cars, loaded them with oil and then contracted three separate railway companies to transport them.

The first carrier was Canadian Pacific Railway, which handed over the train to MM&A in Montreal. From there, MM&A was to deliver the oil cars to a small rail company in New Brunswick owned by the Irving family.

Keep calm, and don’t panic about bee-pocalypse now

Filed under: Environment, Food, Media, Science — Tags: , , , , — Nicholas @ 08:17

You’ve heard about the mysterious colony collapse disorder (CCD) that has been devastating bee colonies across the world, right? This is serious, as bees are a very important part of the pollenization of many crops. As you’ll know from many media reports, this is a food disaster unfolding before us and we’re all going to starve! Or, looking at the facts, perhaps not:

In a rush to identify the culprit of the disorder, many journalists have made exaggerated claims about the impacts of CCD. Most have uncritically accepted that continued bee losses would be a disaster for America’s food supply. Others speculate about the coming of a second “silent spring.” Worse yet, many depict beekeepers as passive, unimaginative onlookers that stand idly by as their colonies vanish.

This sensational reporting has confused rather than informed discussions over CCD. Yes, honey bees are dying in above average numbers, and it is important to uncover what’s causing the losses, but it hardly spells disaster for bees or America’s food supply.

Consider the following facts about honey bees and CCD.

For starters, US honey bee colony numbers are stable, and they have been since before CCD hit the scene in 2006. In fact, colony numbers were higher in 2010 than any year since 1999. How can this be? Commercial beekeepers, far from being passive victims, have actively rebuilt their colonies in response to increased mortality from CCD. Although average winter mortality rates have increased from around 15% before 2006 to more than 30%, beekeepers have been able to adapt to these changes and maintain colony numbers.

[…]

“The state of the honey bee population—numbers, vitality, and economic output — are the products of not just the impact of disease but also the economic decisions made by beekeepers and farmers,” economists Randal Rucker and Walter Thurman write in a summary of their working paper on the impacts of CCD. Searching through a number of economic measures, the researchers came to a surprising conclusion: CCD has had almost no discernible economic impact.

But you don’t need to rely on their study to see that CCD has had little economic effect. Data on colonies and honey production are publicly available from the USDA. Like honey bee numbers, US honey production has shown no pattern of decline since CCD was first detected. In 2010, honey production was 14% greater than it was in 2006. (To be clear, US honey production and colony numbers are lower today than they were 30 years ago, but as Rucker and Thurman explain, this gradual decline happened prior to 2006 and cannot be attributed to CCD).

H/T to Tyler Cowen for the link.

Next up on our agenda of things to panic about is “peak water”

Filed under: Economics, Environment, Technology — Tags: , , , , — Nicholas @ 00:02

sp!ked editor Rob Lyons explains that “peak water” just isn’t something to worry too much about:

Disappointed by the failure of the peak-oil disaster to come to fruition, our doom-mongering, Malthusian friends have alighted on other scary narratives to confirm their suspicions of humanity as a rapacious blight on the planet. Their latest is ‘peak water’.

On the face of it, peak water is a boneheaded concept on a planet where two thirds of the surface is covered in, er, water. According to the US Geological Survey, there are 332 million cubic miles of water on Earth. What we tend to need, however, is not sea water but fresh water, of which there is much less: nearer 2.5 million cubic miles. And much of that is too deep underground to be accessed. Surface water in rivers and lakes is a small fraction of overall fresh water: 22,339 cubic miles. Handily, though, natural processes cause sea water to evaporate and form clouds, which then dump their contents on to land — so in most populated parts of the world there is currently sufficient water to supply our needs in an endlessly renewable way. As for the future, it is clear there is no shortage of H2O on the planet. What we really have is a shortage of cheap energy and the necessary technology to take advantage of the salinated stuff.

The ‘peak water’ theorists focus on groundwater supplies that are either being used faster than they are replenished, or supplies that are not replenished at all: so-called ‘fossil water’. According to leading environmentalist Lester Brown, writing in the Guardian last weekend, the rapid exhaustion of these supplies in some parts of the world is leading to the decline of food production. And at a time of fast-growing populations, this apparently promises disaster for these countries.

But often, the problem is a political rather than a practical one. [. . .]

In reality, all of the fixes that apply to peak oil also apply to peak water. New technology may make water desalination far cheaper than it is now, a claim being made for new water filtration methods based on nanotechnology. Better use of water in irrigation, through careful management of when and how water is applied to crops, could cut usage dramatically — something that is already happening in dry countries such as Israel and Australia and in parts of the US. Current uses of water, like flush toilets, may be superseded in places where water is in high demand. Through civil engineering projects, water can be shifted from places where it is plentiful to places where it is needed most, something societies have been doing for thousands of years.

How many “environmental” groups are actually harming the environment

Filed under: Economics, Environment, Media — Tags: , , , — Nicholas @ 00:01

Willis Eschenbach at Watts Up With That:

Now, given that poverty is the greatest threat to the global environment, the inescapable conclusion is that the only way the global environment stands a chance is if poor countries can develop economically.

And that is why the anti-development, pro-expensive energy stance of the large environmental NGOs is one of the great environmental tragedies of our times.

Here’s the chain of causality:

1. Climate alarmists, with the strong support of the major environmental NGOs like Greenpeace and WWF, declared war on CO2.

2. The method that they chose to fight CO2 was to discourage fossil fuel use by making energy more expensive, using a combination of taxation, legislation, international pressure, and expensive subsidies to achieve that end. Obama’s War on Coal, announced today, is just one of hundreds of examples of the wealthy NGOs and the rich governments working to increase the price of energy.

3. Since energy is development, expensive energy keeps poor countries in poverty. When the World Bank denies loans for coal fired plants in India, the poor suffer … but the environment suffers more. Until they can afford to use coal and gas, they’ll run the country on wood … I refer you back to Figure 1 for how well that works out.

4. Expensive energy slows a country’s economic development, and as President Obama pointed out, people worried about money don’t pay attention to the environment.

This ends up in a bizarre position—the actions of the major environmental NGOs are ensuring continued environmental destruction in the developing world.

Three deaths reported in Calgary flooding

Filed under: Cancon, Environment — Tags: , , , — Nicholas @ 10:13

680News rounds up the reports from Calgary, where the Bow River flooded significant portions of the city yesterday:

Officials are now blaming the devastating flooding in southern Alberta for at least three deaths in the province.

An estimated 100,000 people have been evacuated from their homes, with little information available on when they’ll be able to return.

“I’m not in a position right now to be able to give you timings on neighbourhoods that are along the Bow River and when people may be able to return to those homes, but we are slowly getting there,” said Calgary Mayor Naheed Nenshi.

Many also have no idea whether they’ll have a livable home to return to once the floodwaters finally recede.

Experts say that in some areas, that could still be days.

‘Stunning’ is how Prime Minister Stephen Harper described the flooding in southern Alberta, after he boarded a military helicopter in Calgary to get an aerial view.

Calgary has been one of the hardest hit areas in the western province, and the city was something of a ghost-town Saturday.

There was some positive news for those who have been evacuated, with people in at least one Calgary neighbourhood being allowed to return home Saturday.

During the intial reporting, several Edmontonians were poking fun at Calgary’s plight, but the tone changed quickly once the seriousness of the situation became clear:

The traditional Edmonton-Calgary rivalry went by the wayside, with the provincial capital city promising to send 100 of its police officers to help out where needed.

A total of 1,200 Canadian troops and eight military helicopters have been sent to the city to help local emergency crews with evacuations and sandbagging.

Emergency crews from Ontario, meanwhile, were planning to head out as soon as possible.

“The Ontario Red Cross is at this time mobilizing supplies to help shelter thousands of people in Calgary,” the agency’s Mike Morton said.

The power is off in much of the downtown core in Calgary still, with some of the outages done as a precaution, while others as a direct result of the flooding.

Officials say it could be the middle of next week before all of the lights are back on.

Generating electricity from “biomass” – bad economics and bad for the environment

Filed under: Britain, Economics, Environment — Tags: , , , , — Nicholas @ 09:57

Matt Ridley explains why replacing natural gas (or even coal) electrical generation with biomass is an absurd “solution”:

Under the Government’s plan, biomass power stations will soon be burning much more wood than the country can possibly produce. There is a comforting myth out there that biomass imports are mainly waste that would otherwise decompose: peanut husks, olive pips, bark trimmings and the like. Actually, the bulk of the imports are already and will continue to be of wood pellets.

It is instructive to trace these back to their origin. Reporters for The Wall Street Journal recently found that the two pelleting plants established in the southern US specifically to supply Drax are not just taking waste or logs from thinned forest, but also taking logs from cleared forest, including swamp woodlands in North Carolina cleared by “shovel-logging” with giant bulldozers (running on diesel). Local environmentalists are up in arms.

The logs are taken to the pelleting plants where they are dried, chopped and pelleted, in an industrial process that emits lots of carbon dioxide and pollutants. They are then trucked (more diesel) to ports, loaded on ships (diesel again), offloaded at the Humber on to (yet more diesel) trains, 40 of which arrive at Drax each day.

[. . .]

Over 20 or 40 years, study after study shows that wood burning is far worse than gas, and worse even than coal, in terms of its greenhouse gas emissions. The effect on forest soil, especially if it is peaty, only exacerbates the disparity. The peat dries out and oxidises.

Yet the Government persists in regarding biomass burning as zero-carbon and therefore deserving of subsidy. It does so by the Orwellian feat of defining sustainability as a 60 per cent reduction in emissions from fossil fuels. As Calor Gas puts it: “This is a logical somersault too far, conveniently — for the sake of cherry-picking the technology — equating 40 per cent to 0 per cent.” (Calor Gas supplies rural gas and is understandably miffed at being punitively treated while a higher- carbon rival industry is subsidised. […]) Moreover, unlike gas or coal, you are pinching nature’s lunch when you cut down trees. Unfelled, the trees would feed beetles, woodpeckers, fungi and all sorts of other wildlife when they died, let alone when they lived. Nothing eats coal.

So, compared with gas, the biomass dash is bad for the climate, bad for energy security and dependence on imports, bad for human health, bad for wildlife and very bad for the economy. Apart from that, what’s not to like?

The Economist on the cooling chances of major climate control legislation

Filed under: Environment, Government, Media, Science — Tags: , , — Nicholas @ 09:37

I was disappointed when The Economist switched sides to join the “consensus” on global warming and started arguing for massive government intervention in the economy to “save the planet”. Fifteen years after the last significant bout of warming, The Economist is starting to sound a bit more sensible (and skeptical):

…there’s no way around the fact that this reprieve for the planet is bad news for proponents of policies, such as carbon taxes and emissions treaties, meant to slow warming by moderating the release of greenhouse gases. The reality is that the already meagre prospects of these policies, in America at least, will be devastated if temperatures do fall outside the lower bound of the projections that environmentalists have used to create a panicked sense of emergency. Whether or not dramatic climate-policy interventions remain advisable, they will become harder, if not impossible, to sell to the public, which will feel, not unreasonably, that the scientific and media establishment has cried wolf.

Dramatic warming may exact a terrible price in terms of human welfare, especially in poorer countries. But cutting emissions enough to put a real dent in warming may also put a real dent in economic growth. This could also exact a terrible humanitarian price, especially in poorer countries. Given the so-far unfathomed complexity of global climate and the tenuousness of our grasp on the full set of relevant physical mechanisms, I have favoured waiting a decade or two in order to test and improve the empirical reliability of our climate models, while also allowing the economies of the less-developed parts of the world to grow unhindered, improving their position to adapt to whatever heavy weather may come their way. I have been told repeatedly that “we cannot afford to wait”. More distressingly, my brand of sceptical empiricism has been often met with a bludgeoning dogmatism about the authority of scientific consensus.

Of course, if the consensus climate models turn out to be falsified just a few years later, average temperature having remained at levels not even admitted to be have been physically possible, the authority of consensus will have been exposed as rather weak. The authority of expert consensus obviously strengthens as the quality of expertise improves, which is why it’s quite sensible, as matter of science-based policy-making, to wait for a callow science to improve before taking grand measures on the basis of it’s predictions.

As I wrote back in 2004, “I’ve never been all that convinced of the accuracy of the scientific evidence presented in favour of the Global Warming theory, especially as it seemed to play rather too clearly into the hands of the anti-growth, anti-capitalist, pro-world government folks. A world-wide ecological disaster, clearly caused by human action, would allow a lot of authoritarian changes which would radically reduce individual freedom and increase the degree of social control exercised by governments over the actions and movement of their citizenry.”
