Posts tagged “climate change”
In this week’s episode of R-Squared Energy TV, I answer questions about compressed natural gas (CNG) vehicles, and talk a little bit about global warming. Some of the topics discussed are:
- The environmental footprint of a CNG vehicle versus an electric vehicle operating on natural gas-derived electricity
- The prospects of CNG vehicles in the next 10 years
- Why I generally do not write much about global warming
- The basis of future climate change projections
- The role of feedback mechanisms in climate change
- The basis of the greenhouse effect
- My concerns about the tenor of the debate
- The real “carbon bomb” for the planet
I may bring down the wrath of the internet with this essay – I know from experience that talking climate change in a public forum draws out all the trolls. A changing climate, however, is important enough that our national security planners are studying it closely. The Defense Department, the Intelligence Community, and the Department of Homeland Security are closely studying the effects of climate change, particularly how it will impact our security.
A Changing Climate
First, I will try to pre-empt some criticism from the anti-science crowd by saying that we simply cannot know the future. The climate is notoriously difficult to predict, and models are imperfect. But – climate change is not a matter of ‘belief’ – it is a matter of fact. The fact is that the earth is warming, and has been for at least a century. And, that warming is accelerating: the warmest decade on record was the 2000s, with each of the three decades previous to that warmer than the decade before. Further – it is unequivocal that this warming is being driven by man-made greenhouse gas emissions. I am not a scientist, so I will leave the rest of the explanation to NASA scientist Jim Hansen, who discussed the science of climate change in a recent TED speech.
I will not get into arguments about the science of climate change: I will leave that to the scientists. But, we should all agree that the science is conclusive enough that we cannot simply ignore it – or claim that it’s some sort of UN plot.
Who could have dreamed solving climate change would be so easy? A new paper in Environmental Research Letters called “Greenhouse gases, climate change and the transition from coal to low-carbon electricity” concludes that replacement of all of the world’s currently operating coal-fired power plants — which produce about 40% of the world’s electricity — and replacing them with renewable energy would have an impact of 0.2 degrees Celsius 100 years from now.
Cherry-Picking Conclusions According to One’s Viewpoint
However, a number of climate change websites took away a very different message than I took away from the paper. Here is Joe Romm’s view:
I seem to recall another “bombshell” that he recently reported upon on the same theme: Natural Gas Bombshell: Switching From Coal to Gas Increases Warming for Decades, Has Minimal Benefit Even in 2100. I debunked that by showing that in that particular study, every possible alternative — including wind power, solar power, and even simply shutting down all of the coal plants — was projected to increase global warming in the short term: BOMBSHELL: Solar and Wind Power Would Speed Up, Not Reduce, Global Warming.
But Joe is back with the hyperbolic titles and exaggerations (which I get into below), and he missed the biggest story in the paper.
During my interview last week with Alan Colmes (embedded below), a few points were discussed that warrant some elaboration.
The first is the conversion from winter to summer gasoline, which I have written about in more detail at Why Summer Gasoline Means Higher Prices. Just to be clear, this is an underlying reason that gasoline prices rise at this time every year, but it is not the reason that gas prices are higher today than they were at this time last year. We started the year at a higher level for other reasons, but summer gasoline explains why — even if you took the geopolitical factors out of the equation — that gasoline prices will normally rise from about February to May and then fall from August to November. We do notice this especially in election years, and use it to confirm our belief that politicians or oil companies are influencing prices to win elections.
First There Was Climategate, Now There’s Gleickgate
In 2009, shortly before the Copenhagen summit on climate change, a server at the Climatic Research Unit at the University of East Anglia in the U.K. was hacked. Numerous communications from climate scientists were released to the public, and the name “Climategate” was coined to describe the ensuing controversy. The controversy involved specific comments in some of the e-mails that climate change skeptics immediately seized upon as evidence that some climate scientists were not as objective as they should be, but even worse that dissenting views were being suppressed.
When the Climategate scandal first broke, I had a feeling that the implications were going to be a lot larger than many climate change advocates believed. In fact, I included it among my Top 10 Energy Stories of 2009, writing:
Then came Climategate, which gave the skeptics even more reason to be skeptical. A number of people have suggested to me that this story will just fade away, but I don’t think so. This is one that the skeptics can rally around for years to come. The number of Americans who believe that humans are causing climate change was already on the decline, and the injection of Climategate into the issue will make it that much harder to get any meaningful legislation passed.
Some people commented that the controversy would fade away in a few weeks, but I think in hindsight my assessment was correct. Skeptics had claimed for years that much of the climate change debate was ideological, and Climategate seemingly gave them concrete evidence that this was indeed the case. (I am not making judgments one way or the other; just trying provide the context for the incident and how I felt it would be used by skeptics).
In the first episode of R-Squared Energy TV for 2012, I give a short presentation on global warming. I believe there are a number of misconceptions around the U.S. contribution to greenhouse gas emissions, and I provide some graphics that may surprise some viewers. Some of the topics discussed are: What do I think about global warming? Why do I feel that it is mostly out of the hands of the U.S.? Why do I feel that it will be very hard to rein in emissions in developing countries? I realize that the sound quality on the video needs to be improved, and I am working on that. It isn’t simply a microphone issue, or I would have already resolved… Continue»
Not everyone has the time or inclination to read through a 4,000+ word article, but I felt like the complexity of the issues involved in the controversial Keystone XL pipeline warranted that. In this article I will summarize the key points of the arguments I made in the original, while highlighting where my views diverge from those of the protestors. If you want to see a more in-depth discussion of these issues, please refer to the original article: How I Would Decide the Keystone XL Pipeline Issue Treating the Symptom Rather than the Disease The first issue is to clarify what the pipeline argument is really about. This isn’t really about a pipeline. As one reader pointed out, this is… Continue»
The following is a lengthy essay explaining why I would approve the Keystone pipeline despite finding myself on the side of those concerned over the negative environmental impact of tar sands development. I will debunk much of the misinformation going on in the pipeline debate and ultimately lay out my conclusions. I intend for this to be an alternative to the administration’s announcement to punt the decision for a later time, which I criticized heavily in a previous post. Tip of the Hat to McKibben and the Pipeline Protesters I have to hand it to Bill McKibben. Whether or not you agree with his position, take a look at what he accomplished. McKibben, an environmentalist and journalist, has been described… Continue»
Steeling Myself For Inevitable Controversy I am currently in the middle of writing a chapter on global warming for my book. This actually marks the deepest I have ever delved into the science of global warming. My approach is to explain the science behind global warming; explain which parts of the science are definitely settled, but then also explain why some people have doubts. Of course this debate is so bitter on both sides that merely explaining why some people have doubts is bound to be characterized negatively by some who insist that there can be no doubts. But I can’t overly concern myself about that. I realize that my position is bound to be misrepresented by some. All I… Continue»
Lessons Learned From a Recent Paper on Climate Change Actually, the lessons were learned from the media’s reporting — and the reactions to that reporting — of a recent paper on climate change. The paper I am talking about is a study by Tom Wigley, who is a senior research associate at the National Center for Atmospheric Research (NCAR). The title of the study is Coal to gas: The influence of methane leakage. To review, the study looked at the impact of replacing coal-fired power plants with natural gas-fired power plants. Natural gas emits far less carbon dioxide than coal per BTU of energy produced, and many therefore argue that natural gas is a good bridge fuel on the way… Continue»
