The BBC have very helpfully posted the recent Panorama programme ‘Energy Bills: Power Failure’ on YouTube (as embedded below). Presented by Tom Heap (who regularly does spots on CountryFile), it is very fair-minded and includes contributions from a wide range of people. Therefore, even if you do not live in the UK, I would recommend watching the programme because: it is very good at describing the problems that we all face; and makes it crystal clear that we must find a solution (but does so in a way that somehow avoids being dogmatic).
Some questions I would like help in answering are as follows:
1. What is the instrumental music used in the opening night-time sequence in Blackpool?
2. Why do so many poor people use the most expensive (pay-as-you-go) way to heat their homes?
3. Can we give Angel Gurria (Secretary-General of OECD) a Nobel Prize for plain-speaking?
4. How can anyone avoid concluding that Ed Milliband is an opportunist and a con-man?
5. Why did the CEO of RWE nPower not admit profit margin on generation (as opposed to sales)?
6. Is the need for decarbonisation actually incompatible with power generation being privatised?
7. Why has carbon capture and storage not been made a priority in order to continue burning coal?
8. Is it realistic to think that (in a post-carbon era) energy will ever be cheaper than it is now?
9. When will the UK government admit that fracking is not actually low-carbon and (thus) not the answer?
10. Has Michael Fallon not read the BGS report that says only 10% of shale gas is probably recoverable?
UPDATE (23/12/2013): I think the answer to Q1 is “Burn” by Ellie Goulding (see comments below).
I concluded yesterday’s post, entitled ‘The importance of being earnestly wrong’, by quoting a wonderfully circular argument from Oakwood. This was the assertion that “…you cannot show any one of these [opinions] to be inaccurate, except by appealing to ‘the consensus’…” In reality, the scientific consensus regarding climate science is no more the subject of legitimate debate than the consensus views that: the Universe and the Earth were not created in six days little more than 6000 years ago; the Sun does not orbit the Earth; humans did not co-exist with dinosaurs; and the Earth is not flat.
There are therefore some things about which we humans are no longer wrong (with the exception of those whose approach to science is prejudiced by their ideology or theology).
Yesterday’s post also contained a TED video of a March 2011 talk, entitled ‘On Being Wrong’, given by Kathryn Schulz. This is so good – and so fundamental to appreciating the predicament that Oakwood is in – that I have embedded it here once again.
Schulz warns against automatically assuming that people with opposing views are either ignorant of all the relevant facts, intellectually incapable of processing the information, or deliberately stating things they know to be false. However, she also makes the fundamental point that most people don’t know they are wrong – they are just as convinced that they are not wrong as those who are actually right. This makes it critically important that everyone be willing to accept that they may be wrong. I have done this a lot; and I still do it regularly. However, with regard to climate science, I repeatedly find myself coming back to the logical proposition that:
Doubting the science can only be justified by asserting that the consensus is unreal, unreliable or unreasonable. This does not require all scientists to be liars; but it does require the vast majority of genuine experts to be either stupid, mistaken or mendacious.
Not only would such (implausible, improbable, or insidious) things be without precedent (and require an awful lot of people to be wrong or corrupt), there is also a clear precedent – in the tobacco industry – for the business-funded disputation of highly inconvenient science (which only required a few people to be corrupt in order to fool an awful lot of people).
So, then, because I think it highly instructive – and since it is impossible to breach the confidentiality of someone who chooses to remain anonymous – Oakwood’s email to me is reproduced below (entirely without permission) with rebuttals included in bold text:
“You are entitled to your own opinions but not your own facts.” Yes, that applies to everyone. Here are a few facts:
IPCC models did not predict the current temperature pause. If the IPCC has [now] said ‘because of what we know about the ocean’s massive heat capacity compared to the atmosphere, and the potential for aerosols from growing economies such as India and China, a 15 to 20 year pause is possible’. Of course, they didn’t say that [before], and only come up with the theory after the event. The IPCC do not do the modelling; they merely synthesise the results and summarise the implications. This is therefore statement of belief in either widespread scientific incompetence or political conspiracy. Furthermore, since (1) ice continues to melt (at sea and on land); (2) sea level continues to rise; and (3) ocean pH continues to decline, warming has clearly not stopped. See also ‘How reliable are climate models’ and ‘Global Warming Has Stopped’ on SkepticalScience (SkS).
Proxy temperature data studies cannot reproduce instrumental data for recent decades – when temperatures are at their highest. Therefore, we cannot rely on them to say anything about previous ‘high temperature’ episodes, such as the MWP. This is a complicated issue but this argument has been comprehensively and repeatedly discredited. For example, see ‘Response by Marcott et al’ on Real Climate (with links to other sources of info). As for the MWP, see ‘How does the Medieval Warm Period compare to current global temperatures?’ on SkS.
While so much is made of the Arctic’s ‘record’ low, little is said about the Antarctic’s ‘record’ high, except ‘well that’s different’. Antarctica is geographically isolated and affected by the hole in the ozone layer but, despite this, the West Antarctic and the Antarctic Peninsula are warming as fast as the Arctic. See also ‘Antarctica is gaining ice’ on SkS.
The IPCC finds NO convincing link between extreme weather events (floods, drought, hurricanes) and global warming. Their best is ‘medium confidence’ (for heavy precipitation). (More warm days and fewer cold days is not ‘extreme weather’, but simply a logical outcome of the fact temperatures rose over the 20th C). The IPCC has been repeatedly shown to understate all kinds of risk. Historical analysis of weather in the Northern Hemisphere has shown that extreme weather is becoming more frequent. Multi-decadal change like this cannot be explained without reference to human activity.
IPCC and climate scientists have no idea when the pause will come to an end. Their ‘accurate’ models cannot tell them. This does not matter. Arguing that warming has stopped requires falsification of the evidence that increased atmospheric CO2 is the dominant factor. See ‘It’s not us’ on SkS.
The 97% consensus includes most AGW-sceptics, including me. That is: CO2 is a greenhouse gas; its concentration has increased over the 20th C; it has very likely made some contribution to warming. This myth has been repeatedly debunked. This piece on the RealSceptic blog is the best source of information I have yet seen on how and why this argument is entirely bogus.
There is general agreement amongst climate scientists that a doubling of CO2 on its own will create about a 1dgC rise. CO2 is not acting alone and it is the totality of change that is causing problems. Apart from that facet of reality, this is a very misleading argument, as explained by Michael Mann himself on the LiveScience blog.
Anything more relies on the belief/assumption that positive feedbacks will significantly outweigh negative feedbacks. Ongoing change despite a pause in surface warming implies warming effects are outweighing cooling effects.
But, we’ve had all these discussions before. But you cannot show any one of these facts to be inaccurate, except by appealing to ‘the consensus’ and making nonsensical statements about ‘believing all scientists to be liars’. No, Martin, the practice of science is not about saying: ‘If you disagree with me, you’re calling me a liar’. I have not called Oakwood a liar but, I must admit, he/she does seem to be remarkably incapable of accepting that he may be wrong.
It’s about proper open debate. The fact that the vast majority of ‘sceptics’ are libertarians and/or free-market ideologues proves that the ongoing ‘debate’ is driven by policy implications not any residual uncertainty regarding science. See this excellent essay by Stephan Lewandowsky on The Conversation blog.
While still a minority, there are plenty of climate scientists and experts who do not believe AGW is a major threat. For this to be valid the pool of “climate scientists and experts” would have to be broadened to include all kinds of scientists whose expertise is not relevant. Since we do not generally allow this when discussing evolution or cosmology, why should we do it for climate science?
Of course the answer to that final question is that, as with evolution and cosmology, some people are ideologically opposed to accepting the nature of reality.
I began my previous post by asking the question: “Must the World Bank now be added to the supposed list of environmentally-alarmist institutions seeking to use the perceived threat of climate change as a pretext for imposing global authoritarian government via the United Nations?” I followed this by observing that: “This is essentially the position of all those that dispute the reality of the 97% scientific consensus – or the IPCC’s 95% confidence – that humans are the primary cause of the climate change we are now witnessing.”
‘The Importance of Being Earnest’ is, of course, a very funny and very famous book by Oscar Wilde. Sadly, this post is neither funny nor famous (not yet, anyway). In fact, this post is prompted mainly by a TED video (embedded below) of a March 2011 talk, entitled ‘On Being Wrong’, given by Kathryn Schulz – the author of ‘Being Wrong: Adventures in the Margin of Error’.
As the TED website makes clear, in its biography of her, Kathryn is a journalist who has written articles for a wide range of newspapers and magazines and is also a former editor of the Grist blog. She was a 2004 recipient of the Pew Fellowship in International Journalism (now the International Reporting Project), and has reported from throughout Central and South America, Japan, and, most recently, the Middle East.
Anyone who automatically assumes that people with opposing views are either ignorant of all the relevant facts, intellectually incapable of processing the information, or deliberately stating things they know to be false… needs to watch this video. Although this may sometimes be true, in the vast majority of cases it probably is not.
Earlier this year, the movie ’Greedy Lying Bastards’ went on general release – and so will soon be available on DVD. Accordingly, reviews are now appearing in the media again. This one by Peter Bradshaw on The Guardian website is typical. For many people, therefore, the truth that the fossil fuel companies have financed a longstanding campaign to perpetuate doubt regarding climate science is a well-established fact – as incontestable as the fact that the tobacco industry did exactly the same for decades in order to sell as many cigarettes as possible. However, there remains a sizeable minority of people on this planet for whom, it seems, the very repetition of this fact is proof of its falsity. For these people, who generally decided what they wanted the truth to be a very long time ago, any evidence that they are wrong is proof that they are right (or that the person presenting the evidence has been duped by – or is part of – the conspiracy to perpetuate a lie).
Of course, if you try and point this out to such people, you are accused of peddling your own conspiracy theory. However, tobacco companies have been taken to court and found guilty of trying to hide the link between cancer and smoking. Climate scientists have only ever been taken to court for saying things fossil fuel companies do not want us to hear. This too will be dismissed by the factually-challenged as evidence of a wider conspiracy; now including the judiciary. However, for these people, is there no point at which the simplest explanation (which is supported by observable and documentary evidence) becomes more reasonable than an ever-expanding conspiracy (which is not supported by the vast majority of available evidence)?
This brings me back to something else I said on my previous post:
Unfortunately, for such conspiracy theorists, the truth of the matter is much more unpleasant: Climate scientists are not engaged in a global conspiracy to provide the UN with an excuse to subvert the power of national governments. Conspiracy or not, it would be bad enough if our national governments had spent the last 25 years ignoring the warnings of climate scientists. However, the truth of the matter is even more insidious: The IPCC has spent the last 20 years or so compiling reports detailing the nature, scale and urgency of the problem we face, only to have our national governments systematically neuter their reports and ignore the warnings they contained.
So, again, the question remains: What about all those people who are not being paid to misinform (i.e. the so-called ‘Merchants of Doubt)’? How do we explain their existence – and how can we tell the difference between those who are being deliberately deceitful and those who are merely wilfully ignorant? To be blunt, how can we spot the difference between someone who is just bigoted and someone who is being paid to be wrong?
I am afraid that I do not know for sure but, having spent an entire year carefully examining all the evidence, I am entirely satisfied by the scientific, historical, and observational evidence – and the logical arguments – that the burning of fossil fuels is altering the Earth’s climate. Therefore, although I can never be certain, despite everything Kathryn Schulz says in the above video, I think it is legitimate to question either the sanity or motives of anyone who repeatedly ignores the fact that their arguments have been shown to flawed; and/or repeatedly re-states things that can easily be determined to be false.
No-one should be in any doubt about this: such people are not being sceptical; they are in denial.
Sadly, I recently had to delete an entire comment on my most recent post by someone identified only as ‘Oakwood’. He or she claims a professional need to remain anonymous but spends an awful lot of time posting comments on blogs by non-experts such as Anthony Watts (WattsUpWithThat), Steven McIntyre (ClimateAudit) and Andrew Montford (BishopHill). It is, therefore, not that surprising that much of the content of what Oakwood’s comments elsewhere can be traced back to things by these non-experts (whose arguments have all been repeatedly falsified and discredited).
I therefore decided to send Oakwood an email in which I started by saying, “You are entitled to your own opinions but not your own facts…” In response, Oakwood started by saying he agreed with that assertion but, sadly, followed it with yet another re-statement of his own “facts” that are not actually facts at all… Then, as if to add insult to injury, Oakwood followed that litany of previously debunked arguments and climate myths (which I will look at in detail tomorrow), with this masterpiece of unfalsifiability:
…you cannot show any one of these facts to be inaccurate, except by appealing to ‘the consensus’ and making nonsensical statements about ‘believing all scientists to be liars’.
This is a self-sealing argument that is entirely predicated on conspiracy theory: If the consensus is real, reliable and reasonable, there is no legitimate reason to doubt the science. Therefore, doubting the science can only be justified by asserting that the consensus is unreal, unreliable or unreasonable. This does not require all scientists to be liars; but it does require the vast majority of genuine experts to be either stupid, mistaken or mendacious.
Tomorrow, probably not for the last time, I will rebut all of Oakwood’s “facts” in part two of this series, entitled: ‘The imprudence of being earnestly Oakwood’.
Must the World Bank now be added to the supposed list of environmentally-alarmist institutions seeking to use the perceived threat of climate change as a pretext for imposing global authoritarian government via the United Nations? This is essentially the position of all those that dispute the reality of the 97% scientific consensus – or the IPCC’s 95% confidence – that humans are the primary cause of the climate change we are now witnessing.
Unfortunately for such conspiracy theorists, the truth of the matter is much more unpleasant: Climate scientists are not engaged in a global conspiracy to provide the UN with an excuse to subvert the power of national governments. Conspiracy or not, it would be bad enough if our national governments had spent the last 25 years ignoring the warnings of climate scientists. However, the truth of the matter is even more insidious: The IPCC has spent the last 20 years or so compiling reports detailing the nature, scale and urgency of the problem we face, only to have our national governments systematically neuter their reports and ignore the warnings they contained.
Similarly, it seems, our national governments appear determined to ignore warnings from professional bodies, national scientific academies, and international organisations. Anyone who asserts that humanity needs to stop burning fossil fuels as fast as possible is, it seems, immediately dismissed as an environmental ‘alarmist’.
If you stop to think about it objectively, even for a moment, the reasons for this are very obvious: Far more serious even than the USA defaulting on its debt repayments, the problem is that the share prices of the World’s fossil fuel companies are entirely dependent upon the assumption that all the Earth’s fossil fuels will be burned. This is referred to as ‘business as usual’ (BAU).
Thus, in the minds of our politicians at least, if they accept the reality that we have a problem at all, the only solution to the problem is one that allows fossil fuel companies to continue with BAU.
Unfortunately for our politicians, fossil fuel companies, and all life on Earth (human and non-human), such a solution does not exist and is, almost certainly, technologically unachievable in the timescale that it would now be required.
The solution everyone is hoping will emerge is carbon capture and storage (CCS). This is a subject about which I have written a great deal; and I do not intend to repeat myself now other than to say this: CCS will only be able to help solve our problem when the rate of removal of CO2 from our atmosphere is greater than global emissions. Getting CCS to work will take decades (as will decarbonising our economies). It is quite possible that we do not have decades of time in which to do either but, one thing is for sure, it makes no sense to delay making a serious attempt to do either.
Therefore, I believe all would do well to ponder the question as to why the World Bank published ‘Inclusive Green Growth: The Pathway to Sustainable Development’ last year. There is a big clue given in the ‘Abstract‘, which reads as follows:
Economic development during the next two decades cannot mirror the previous two: poverty reduction remains urgent but growth and equity can be pursued without relying on policies and practices that foul the air, water, and land.
The World Bank accepts that humanity cannot go on treating the Earth with contempt; treating it as if both its resources and regenerative capacity are infinite. This is because, as is becoming increasingly obvious (in the case of the latter at least), they are not infinite.
This brings us to the crux of this post, which is to refute the entirely bogus argument that we humans have nothing to be afraid of because climate change is natural; life has survived it in the past; and will therefore do so again. There are at least two problems with this line of argument:
1. Because we were already in a warm interglacial period – and atmospheric CO2 is now 40% higher than at any time in the last 1 million years – it is highly unreasonable to dispute the fact that post-Industrial warming is unnatural (i.e. all sparrows may be birds but not all birds are sparrows).
2. In the entirety of Earth history, there have been 5 mass extinction events (i.e. periods when between 50 and 95% of all species have been wiped out). These events are each associated with periods when global average temperatures were more than 5 Celsius warmer than they are now (and there is strong evidence that a sixth mass extinction is already underway).
In responding to sensible comments on my previous post, ‘A summary of the ‘Climate Departure’ research of Mora et al.‘, I found myself referring to the most recent mass extinction event in the Earth’s history, the so-called Palaeocene-Eocene Thermal Maximum (PETM), which occurred 55 million years before present (MaBP). However, as the following video graphically demonstrates, what is now happening to the Earth’s climate as a result of the post-Industrial burning of fossil fuels, is looking increasingly like the Permian mass extinction event, which occurred 252 MaBP.
This video is only about 10 minutes long, so I hope people will watch it. If not, however, the main points are summarised below:
1. There have been five mass extinctions before and humans are now almost certainly causing a sixth.
2. The ongoing melting of terrestrial ice will now cause sea level to rise continuously for several centuries.
3. This is probably unstoppable but is survivable (i.e. assuming all humans can move away from coastal areas).
4. All past mass extinction events occurred when global average temperatures > 5 Celsius warmer than now.
5. Common to each event is further rapid warming triggered by methane release from permafrost and seabed.
6. We already have evidence that rates of both species extinction and methane release are now accelerating.
7. Positive feedback mechanisms (such as disappearing sea ice) will soon make methane release unstoppable.
8. If this ‘tipping point’ is passed, anthropogenic climate disruption will almost certainly be unsurvivable.
This is why the World Bank agrees that we need to decarbonise our global economies as fast as possible.
Although much delayed and interrupted by other stuff, this is now the third part of my review of The Revenge of Gaia, as published by James Lovelock in 2006. The first and second parts were published on this blog last month (i.e. here and here).
Once again, I will assume the reader is familiar with the concept of Gaia (as described in part one of my review and on Wikipedia). Also, as discussed in part two of my review, I will also assume the reader is aware of Lovelock’s subsequent attempts to repudiate his ‘alarmism’ (April 2010) and, even more astonishingly, disavow his faith in the objectivity of climate scientists (June 2012). However, in all of this, I hope readers will recognise that I am trying to be pragmatic and objective; as opposed to dogmatic and prejudiced.
Previously, I had got as far as Lovelock’s assertion (circa 2006) that humanity needs to get off its addiction to fossil fuels as quickly as possible. Therefore, I now continue by looking at the ways in which he suggests we might (or indeed might not) do that. However, it must be stressed that Lovelock accepts (or at least accepted) that carbon capture and storage (CCS) will not prevent excessive climate disruption unless we decide to leave most fossil fuels in the ground (or radically reduce the rate at which we are burning them).
Lovelock’s first non-fossil fuel option is hydrogen; and his first point is that, as with electricity, hydrogen has to be manufactured. In addition to pointing out that it can be manufactured from fossil fuels and in nuclear reactors, Lovelock explains how hydrogen can be produced from water by hydrolysis. However, the problems inherent in transportation and distribution of hydrogen (e.g. very low atomic mass and high explosive potential) and the low amount of energy return on energy input (EROEI) mean that this is unlikely ever to be commercially viable.
In contrast to this, hydrogen could be widely used in fuel cells (i.e. as used to generate electricity on the command module in the Apollo missions), although this is not without its own problems and dangers. Wikipedia has a good summary of methods of hydrogen production, from which the important takeaways appear to be that hydrogen is:
(1) mostly produced from hydrocarbons (steam reforming); and
(2) mostly used in oil refineries to derive lighter products from heavy ones (hydrocracking); or
(3) used in other chemical processes to produce other things (e.g. ammonia and methanol).
Both Lovelock and the above Wikipedia article refer to the potential of a hydrogen economy. Indeed, Lovelock refers specifically refers to the work of Geoffrey Ballard – who pioneered the concept of cars powered by hydrogen fuel cells (i.e. like rechargeable batteries), which would consume hydrogen in use (by driving an electric motor) and generate it when not in use (by being recharged).
Expressing his hope that this technology will become widespread, Lovelock moves on to explain why he hopes that renewable technology will not: In essence, his objections are based on:
(1) low EROEI (i.e. in manufacture of hardware with a low energy conversion efficiency); and
(2) low energy density (i.e. need for large areas of land to be given over to electricity production).
Lovelock suggests that the concept of sustainable development has been hijacked by those who promote renewable energy as a means of avoiding dealing with the impossibility of perpetual economic development on a finite planet with finite resources. This is a point on which I would agree – and have agreed (as published here by the Geological Society of London). However, even so, I find his complaints about the industrialisation of the countryside somewhat tiresome. The bottom line is this: anything that reduces our dependency on fossil fuels must be a good thing; as must be the use of any fossil fuels consumed in working towards that goal.
Lovelock does himself no credit whatsoever by suggesting that pursuit of wind power is short-sighted because climate change will alter planetary atmospheric circulation. Such an assertion is almost (but not quite) as stupid as suggesting that harnessing the Earth’s tidal energy is likely to slow the Earth’s speed of rotation (to any significant extent). Similarly, his suggesting that the UK would need 276 thousand wind turbines (each 100m high) to meet national demand for electricity is nothing more than a straw man argument (because no-one is suggesting that this can or should be the aim and it ignores the agreed need for overall consumption to be reduced).
Lovelock’s comments about tidal energy, pre-date the development and testing of numerous technologies (e.g. around the Orkney Islands off the north coast of Scotland), but he does make the valid point that, as with CCS, it will take decades for any technology to become widely available and implemented. However, this does not change the fact that it would be almost insane for an island nation such as the UK not to pursue these technologies. The down-side to all this is that it will require additional power distribution infrastructure to be built. However, so will micro-generation (as opposed to centralised generation), unless everyone is to become self-sufficient and not feed-in unused power to the national network (the income from which is the main reason most people install the systems).
Lovelock then moves on to consider hydro-electric power (HEP). He makes the point that HEP is not without environmental cost (loss of farmland, enforced displacement of populations, and interference with fluvial deposition patterns including the benefits of regular flooding of farmland). However, he also seems to ignore the fact that HEP can be of considerable benefit to communities in areas where population density, competition for land and ecological carrying capacity are all low.
On the subject of biofuels, Lovelock merely re-states his objections to the diversion of agricultural land away from producing food (and takes another swipe at those who favour the inherently inefficient use of land for organic farming). It is on this subject that the intellectual incoherence of Lovelock’s position is most clearly displayed: being simultaneously pessimistic (about the prospects for so many people living on such a small planet) and optimistic (about the potential for technology to solve all our problems) – especially if we embrace GM crops.
However, given that he could not possibly have heard of it in 2006, Lovelock may be forgiven for not mentioning a new avenue for sustainable biofuel production that emerged in 2010 – namely GM algae that photosynthesise ethanol (instead of glucose). However, even this may now be eclipsed by the potential of the latest idea – higher mixed alcohol fuels. These can be produced form any solid, liquid or gaseous waste product and, therefore, could solve all our energy problems (but only if fossil fuel companies don’t buy up the patents to such ideas and then make them disappear).
Finally, in his long preamble to consideration of the future potential of civil nuclear power, Lovelock turns his attention to solar energy: Here, once again, his argument is primarily based on low EROEI and on the cost of manufacturing the hardware (not to mention all the other finite metallic resources required).
On this front, I must confess I have some sympathy: Harnessing the energy the Earth receives from the Sun (especially in mid-to low latitude countries where population densities are and probably will remain low) would seem like an obvious choice. However, pursuing solar power generation on a large scale simultaneously in a large number of countries would have a serious impact on the demand for – and cost of – copper (and other even rarer metals), which is already high as a consequence of the success of hand-held electronic devices such as mobile phones.
As for Lovelock’s justification for his pro-nuclear stance, that will be the subject of the next post in this series (although I am not promising when that will be).
…At the going down of the Sun, and in the morning, you should remember them.
The following is extracted from a post on the Center for American Progress (CAP) website yesterday, by Daniel J. Weiss, Senior Fellow and Director of Climate Strategy at CAP, which was entitled, ’10 Truths that Should Be Said at This Week’s House Climate Change Hearing. The article was published in advance of yet another travesty of modern democracy on Capitol Hill this week – a House of Representatives Committee meeting where scientifically illiterate politicians try to validate their prejudiced beliefs by getting scientists to tell them that anthropogenic climate disruption is just a smokescreen for a Communist and/or Zionist plot to stall Western development. However, I should really let Daniel explain the context…
This Wednesday, September 18, the House Energy and Power Subcommittee will conduct a long-overdue hearing on climate change. It is unfortunately not to seek scientific facts from reputable institutions, such as the National Academy of Sciences, the American Meteorological Society, and similar experts, as requested 27 times by Ranking Committee and Subcommittee Members Henry Waxman (D-CA) and Bobby Rush (D-IL). Instead, the hearing is titled “The Obama Administration’s Climate Change Policies and Activities.”
The scheduled witnesses are Secretary of Energy Ernest Moniz and Environmental Protection Agency Administrator Gina McCarthy. During the hearing, they will probably be subjected to a barrage of phony claims by the 14 climate-science deniers who are serving on the subcommittee in an attempt to discredit President Barack Obama’s Climate Action Plan. These members undoubtedly will repeat the false and misleading claims made by the big polluting utilities, coal companies, oil companies, and other special interests that profit from the status quo of no limits on carbon pollution.
Instead of these stale attacks on settled climate science, hyperinflated estimates of the cost of cleanup, or denial of executive authority to act, here are 10 truths that should be said at the hearing.
Here, then, is the list of 10 facts. Anyone feeling the need to dispute any of the following needs to explain the existence of all data from which the reality of these facts has been deduced (see CAP website for details).
1. Climate science is settled.
Similar to the tobacco industry denying that smoking cigarettes can cause cancer, many big polluters and organizations funded by them continue to deny the link between burning fossil fuels and climate change. Nonetheless, the overwhelming scientific verdict is in: Industrial carbon and other pollutants are responsible for climate change.
2. Climate change harms Americans and our economy.
Spewing carbon pollution into the air may be free to coal-fired power plants and oil refineries, but Americans bear the costs. The 25 most damaging climate-related storms, floods, heat waves, droughts, and wildfires in 2011 and 2012 took more than 1,100 lives and caused a total of $188 billion in damages. The number of these extreme weather events, as well as the price tag, has grown over the past three decades.
3. Military leaders warn that climate change will harm national security.
Earlier this year, U.S. Pacific Command Commander Adm. Samuel J. Locklear III said that climate change poses the greatest security threat in the Pacific region. What’s more, the Defense Department’s latest Quadrennial Defense Review Report warned that climate change “may act as an accelerant of instability or conflict, placing a burden to respond on civilian institutions and militaries around the world.”
4. There is no limit on carbon pollution from power plants.
Power plants are responsible for 40 percent of the industrial carbon pollution emitted in the United States. Yet these plants can generate unlimited tons of carbon pollution, even though there are restrictions on their mercury, acid rain, and smog pollution. President Obama’sClimate Action Plan would set carbon-pollution standards for new and existing power plants.
5. The Environmental Protection Agency has the authority to set carbon-pollution standards.
The Supreme Court’s 2007 decision in Massachusetts v. EPA ruled that climate change pollutants are covered under the Clean Air Act, and as such, the agency’s administrator must consider whether these pollutants “may reasonably be anticipated to endanger public health or welfare.” If the administrator finds that this is the case, he or she has the authority to limit pollutant emissions. President George W. Bush’s EPA Administrator Stephen Johnson and President Obama’s Administrator Lisa Jackson both made this endangerment finding based on science. This decision provides the legal basis for the EPA to set carbon-pollution limits on power plants, oil refineries, and other major industrial polluters.
6. Pollution-reduction programs create jobs.
Requirements to reduce air pollution create jobs because they require companies to invest in new equipment, practices, or technologies, all of which generate additional employment. Likewise, a carbon-pollution standard for power plants would generate thousands of jobs in labor-intensive energy-efficiency retrofits in buildings; the manufacture, installation, and operation of wind and solar power; and other investments necessary to slash this pollution.
7. Carbon-pollution reductions will increase energy efficiency, saving consumers money.
Reducing wasteful electricity is a cost-effective way to reduce carbon pollution from coal-fired power plants. This involves improving transmission lines, employing smart-grid technology to better manage electricity use, and making buildings and homes more efficient. Using less electricity will also save consumers money by lowering their electric bills.
8. Carbon-pollution reductions are affordable.
Resources for the Future, or RFF, a nonpartisan think tank, estimates that a “4 percent reduction in the average emissions rate [of power plants] … results in a reduction of 93 million short tons of carbon dioxide emissions” but would lead to an electricity-rate rise of only 1.3 percent. This approach would achieve $25 billion annually in net benefits, according to RFF. With energy efficiency measures, consumers could actually save money because they will use less electricity.
9. U.S. leadership will increase worldwide pollution reductions.
Time and again, the United States recruits other nations to join its climate-pollution-reduction efforts. Earlier this month, the members of the G-20 agreed to support additional measures to use the Montreal Protocol to phase down hydrofluorocarbons, or HFCs—a super pollutant that is a significantly more potent climate pollutant than carbon dioxide. China recently announcedthat it will ban new coal-fired power plants in three regions, including Beijing, in order to cut its share of coal usage to below 65 percent by 2017.
10. Regulations prompt increased investment and innovation to reduce coal pollution.
