Another Record Year for CO2

Introduction

This is the 4th installment in a series that examines data from the recently released Statistical Review of World Energy 2014. The previous posts covered the world’s growing fossil fuel consumption:

Today I examine the implications of that growing fossil fuel consumption by looking at carbon dioxide emission trends. The key points in the report include: CONTINUE»

Hoping for a Rational Climate Change Discussion

The Best Path Forward on Coal?

This week the Wall Street Journal is running the latest set of answers from their “Experts Panel.” Four questions were posed to the energy panel, and I chose to answer three of them. (The 4th was about solutions to the drought in the Western US — which I don’t feel qualified to answer). The first question I answered was “What’s the best way to move forward on coal?” – and my answer was published yesterday: The Case Against Burning Coal. That was followed up with a podcast “debate” between former Shell President John Hofmeister and myself on coal’s future: Time to Stop Burning Coal? WSJ Experts Debate.

I suppose the topic of climate change will always be polarizing. One side believes that fossil fuel consumption threatens our very existence while the other sees climate change as a huge scam that threatens to destroy economic progress. Of course there are many shades of gray between these extremes, but those with the most extremist views are generally the loudest voices.

Today I hope to engage some of those loud voices with a rational, fact-based discussion. CONTINUE»

Keystone XL’s Emissions Versus Coal-Fired Power

Another Courageous Punt

I hadn’t planned to write yet another Keystone XL pipeline article, but I have gotten a lot of questions since the recent announcement by the Obama administration that they are still unable to make a decision on the project. I agree with the Washington Post’s assessment of the situation, that this is now into absurd territory.

At this point I don’t think the project will be approved by this Administration, although it could be approved by the next. I think this is a simple political calculation by President Obama, that by foot-dragging and delaying he is keeping his environmentalist allies at bay, but without all of the political fallout around Democratic Keystone XL supporters should he simply reject the pipeline.

This is one reason I would make a terrible president. I can’t play games like this. You make a decision. It can go one of two ways. You can say “I am going to make a stand along with my environmentalist allies who voted me into office and reject a continued expansion of fossil fuel infrastructure.” That would be a courageous stand, albeit one more steeped in symbolism than in measurable climate impact. More on that below. CONTINUE»

How Do You Justify Consuming ExxonMobil’s Oil?

Introduction

Sometimes the written word is easy to misinterpret. More than once I have written an article to find that some minor point I made became the focus, or that the point I was making was just lost. Most of the time that’s my fault, but sometimes it’s because an editor wanted to spice up the title and make it a bit more controversial. In that case, that can inflame the reader before they even begin to read, and they either make comments based on a misleading title, or they read the article with significant bias.

I think there is a risk of misinterpretation with today’s article, so I want to spell out my intent up front. This should not be read as a defense of ExxonMobil or their business practices, because that’s not what it is. It’s an attempt to get the reader to understand how they think, and why they do some of the things they do. Importantly, you may not be able to understand their actions given your view of the world. It’s not because they are simply denying reality so they can keep making money, they just don’t see the same things you see. Here is my attempt to explain that.

A Carbon Asset Bubble?

The 2009 Copenhagen Accord on climate change stipulated that if the worst impacts of climate change are to be avoided, we have to stop taking fossil fuels from the ground and burning them. Doing so has been increasing the carbon dioxide in the atmosphere for the past two centuries. Former Vice President Al Gore has been but one high profile voice advocating for leaving those fossil fuels in the ground, which would create a big problem for fossil fuel companies whose value is based on their fossil fuel reserves. Gore outlined his position last year in a Wall Street Journal editorial The Coming Carbon Asset Bubble.

Oil Sands and the Environment – Part II

Introduction

Today I continue coverage of my recent visit to the Athabasca oil sands near Fort McMurray, Alberta. I was there as a guest of the Canadian government, which hosts annual tours for small groups of journalists and energy analysts. I will be covering multiple aspects of oil sands production in a series of posts.

In last week’s post — Oil Sands and the Environment – Part I — I discussed greenhouse gas emissions, impacts on wildlife, and I touched upon water usage. I also detailed some of the work of Pembina Institute (PI), which is working to improve the environmental conditions as the oil sands are developed. Today’s article will discuss the tailings ponds, water consumption, impacts to water quality, and impacts to indigenous people.

Tailings Ponds

There are two primary ways of extracting bitumen from the oil sands. In situ production involves injecting steam into the ground to heat up the bitumen which is then pumped out of the ground. Surface mining is done when the resource is fairly close to the surface. During my trip we visited one in situ producer – Cenovus Energy – and one surface miner – Canadian Natural Resources Limited (CNRL). These methods will be discussed in greater detail in next week’s post. CONTINUE»

Oil Sands and the Environment – Part I

Introduction

I spent the past week in the heart of the Athabasca oil sands in Fort McMurray, Alberta. I was there as a guest of the Canadian government, which hosts annual tours for small groups of journalists and energy analysts. During my trip I was told that the only person who ever asked as many questions as I did was when David Biello from Scientific American was a guest. (You can read one of David’s articles from his trip here).

I felt like I learned enough to write a book on the oil sands, so I have a great deal of information I want to share with readers in a series of articles. In these articles I will provide an overview of the oil sands, compare and contrast the different ways of processing them, discuss the environmental issues, and then discuss the particular companies that I visited on this trip — Cenovus Energy and Canadian Natural Resources Limited.

I want to start this series with a 2-part discussion on the environmental issues. Generally when people think of oil sands, the environmental issues are foremost on their mind. That has always been the case with me, so most of the questions I asked during my trip related to the impact of oil sands development on the environment. This is a very contentious issue, and one in which the battle lines have been drawn. CONTINUE»

The Ice That Burns

A Kindred Spirit

I have a very busy travel schedule this week, so this one is a little bit late and a bit rushed.

Last week I had the pleasure of meeting Gal Luft, co-director of the Institute for the Analysis of Global Security (IAGS). It was a funny sort of meeting, because I didn’t know he was coming, as he had come to visit someone else. When I was introduced to him we both said to each other “Hey, don’t I know you?”

We figured out that the reason we knew of each other is that we have both been advocates of using methanol as fuel. In fact, I referenced Dr. Luft and his frequent co-author Anne Korin in my book Power Plays. During his visit, he left a copy of their most recent book Petropoly: The Collapse of America’s Energy Security Paradigm. CONTINUE»

The Carbon Dioxide Problem Worsens

Introduction

This is the 6th and final installment in a series that examines data from the 2013 BP Statistical Review of World Energy.

The previous posts were:

Today’s post looks at carbon dioxide emissions, and if you are concerned about climate change the results aren’t good.

The “highlights” are:

  • Global carbon dioxide emissions increased by 1.9% to reach a new record high in 2012
  • China led all countries in the categories of most carbon dioxide emitted and the greatest increase in emissions
  • The US had the greatest decline of any country, with carbon dioxide emissions falling by 217 million metric tons from 2011 levels
  • However the US is responsible for 25% of the carbon emitted to the atmosphere over the past 50 years
  • Of the countries tracked, 25 saw decreased carbon dioxide emissions from 2011 levels and 39 countries experienced increased emissions

Emissions Keep Climbing

Global carbon dioxide emissions increased to 34.4 billion metric tons (BMT) in 2012. This was a new global record, 1.9% above the previous record set a year earlier. Over the past decade carbon dioxide emissions have increased by 32%. And since 2004 the increase in global emissions has been 5.9 BMT, which is an increase greater than total US emissions.

Protecting a Drowning Man from Sunburn

Later this week I intend to start a series covering the recently released BP Statistical Review of World Energy 2013. However, first I want to follow up on last week’s post The Increasing Irrelevance of the Keystone XL Debate. With few exceptions, the post was well-received by people on both sides of the debate. There was some reasonable debate on the post on my Twitter feed, and much less rancor. I think only one person accused me of being an “enemy combatant” while most recognized that I am sincerely trying to shine a light on a problem that I see as orders of magnitude worse than Keystone XL.

The primary objection to my argument over the irrelevancy of Keystone XL is the same one that has been voiced in the past. It is that the Keystone XL project itself may be relatively insignificant, but add up many Keystone XL projects and you get a big effect. The only problem is that this really isn’t even true.

In last week’s article I referenced a 2012 paper by Neil C. Swart and Andrew J. Weaver from the School of Earth and Ocean Sciences, University of Victoria published in Nature Climate Change. That paper contained a graphic that I shared on Twitter, and it got quite a bit of commentary. The graphic shows the relative potential warming contributions of various fossil fuel resources:

The Increasing Irrelevance of the Keystone XL Debate

Keystone XL’s Insignificant Contribution to Climate

Last week President Obama unveiled a new plan to combat climate change in a speech at Georgetown University. While there is generally broad consensus that his comments further threaten the already battered US coal industry, his comments on TransCanada’s (TSX: TRP, NYSE: TRP) Keystone XL pipeline project had pundits guessing at his meaning. Here is what the President said in his speech about Keystone XL:

Now, I know there’s been, for example, a lot of controversy surrounding the proposal to build a pipeline, the Keystone pipeline, that would carry oil from Canadian tar sands down to refineries in the Gulf. And the State Department is going through the final stages of evaluating the proposal. That’s how it’s always been done. But I do want to be clear: Allowing the Keystone pipeline to be built requires a finding that doing so would be in our nation’s interest. And our national interest will be served only if this project does not significantly exacerbate the problem of carbon pollution. The net effects of the pipeline’s impact on our climate will be absolutely critical to determining whether this project is allowed to go forward. It’s relevant.

The reason that there have been widely differing views on the President’s intentions boils down to his use of the phrase “only if this project does not significantly exacerbate the problem of carbon pollution.” The State Department’s Draft Supplementary Environmental Impact Statement (SEIS) for the Keystone XL Pipeline project already concluded that approval of the project would have little impact on global carbon dioxide emissions or on the development of the oil sands because of their view that the oil will get to market one way or another. More on that below. CONTINUE»
