What Comes Next?

I’m not really sure how I feel about Copenhagen.

In a way, I was pleasantly surprised that anything happened at all. I had been following the feeds from DeSmogBlog and U of T throughout the conference, and it was after midnight on the last evening before any agreements were actually made.

Obviously, Copenhagen didn’t progress to the stage it was supposed to. However, I feel that the stage that was reached was successful. For unsubstantiated, unexplained goals to simply “take note of”, they’re certainly very good goals.

I’m also pleased that it was China and the US who finally sat down to get something done. As the the largest emitters and largest economies in the world, all the other countries are going to follow whatever they do. And I’m glad that the senior leadership (if not the legislative assemblies) from both countries seems to be pushing in the right direction.

It ended up better than I expected. But it still isn’t enough. We really should have reached this stage 20 years ago. We’re far behind schedule, and we don’t seem willing to catch up.

A Thought

If our world leaders cannot cooperate enough to stop dangerous climate change in the scant time we have left…..how do they expect to be able to cooperate enough to adapt to the kind of world they’re committing to with their inaction?

If we can’t figure this out, how do we expect to able to get along in what we’re choosing instead?

Science and Communication, Part 1

Usually books about climate change take me some time to read. As fascinating as they are, they’re not the kind of literature I would read to relax. They take far more energy to get through than something like Twilight.

This wasn’t the case for Science as a Contact Sport, the new book by Stephen Schneider. I couldn’t put it down – I absolutely whizzed through it. The narrative wasn’t about explaining scientific processes as much as describing what it’s like to be a climate scientist, and how that has changed since the early 1970s. Perhaps my enjoyment of the narrative was due to the fact that I think I like memoirs – although the only other memoir I’ve read is Memoirs of a Geisha (and wasn’t that fictional?) In any case, Science as a Contact Sport was a memoir of the kind of person I want to follow in the general footsteps of: someone who studies climate change, particularly modelling and radiative balance, and has a good sense of how to accurately communicate science to the media and the public.

Schneider has been studying climate change for a long time – he’s literally one of the pioneers of climate modelling – so his story was able to begin in the 1970s. There were quite a few familiar figures in the early narrative, including James Hansen as a PhD student (there was even a photograph!) and Richard Lindzen, who was brilliant but had unusual views on how to communicate uncertain science to the government and the public.

I was fascinated by the insider’s account of the 1970s radiative forcing debate – which would win out in the end, aerosols or greenhouse gases? As Schneider was the co-author of one of the few papers that predicted a cooling, he was able to explain the problems with that paper and why it was quickly discredited. Firstly, the climate model used for the paper didn’t have a stratosphere, so the climate’s sensitivity to CO2 was underestimated by a factor of 2. Secondly, the paper incorrectly assumed that aerosols would evenly disperse globally, like greenhouse gases do. It was very early on in the study of both aerosols and climate modelling, so Schneider’s mistake wasn’t a big deal to the scientific community – but it sure keeps coming up in editorials and YouTube comments these days.

The thesis of the book was that being a climate scientist in the 1970s was very different to the way it is now. In the early 70s, Schneider and his colleagues pounded away at the frontiers of their fields and filled their minds with purely analytical questions. Those who talked to the media about their work were reprimanded, and some scientists even questioned the integrity of creating assessment reports for the government.

Today, however, climate scientists create major international assessment reports every few years, while politicians try to sabotage the process. They are morally obliged to talk to the media, unless they’re happy with the media talking to Fred Singer instead. And even so, editorials and Fox News segments are all too happy to twist whatever they say in hopes to damage the credibility of their field.

Science used to just be about science. Now, as scientists studying an area that is socially and politically important, Schneider and his colleagues have to be adept at both science and communication. The book provided some great suggestions for improvement. One of my favourites was to take the first half hour of each conference to summarize what was known in that field, so that the journalists present wouldn’t witness only the cutting-edge discussions and come away thinking that climate science was uncertain because the scientists all disagreed.

Science as a Contact Sport was a fantastic book that had a lot to say about the nature of science, scientific literacy in the public, and the state of science journalism. A lot like Chris Mooney’s new book, Unscientific America, but specific to climate change. It really got me thinking about the vast chasm between scientists and the public and how we should address it, to the point where it’s inspired a whole series of posts. Keep your eyes open for part 2 – coming soon.

The Worst in the World

Stephen Harper is coming to Copenhagen. It really surprised me when the Canadian media started patting him on the back for announcing this, as if he was finally cleaning up his act and showing some leadership. Coming to a conference – and most likely only for a day or two, for a photo op – doesn’t show leadership. As I’ll explain in this post, it’s the latest in a chain of attempts by the Canadian government to look like they’re doing something about climate change, without actually doing anything at all.

Obama is only coming to Copenhagen for one day. Almost certainly a photo op. But I find this somewhat more excusable because the US is already working on their own climate change legislation, independent of Copenhagen. The US has something against international agreements, but they’re being proactive and finding ways to achieve the same ends regardless. Canada hasn’t done any such thing.

And it’s not just the Conservatives that are being difficult. Michael Ignatieff, the leader of the opposition, says that Canada has wasted four years on climate change action. Actually, we’ve wasted twenty. But Ignatieff will only say four years, because beyond that, it was his party that was the problem. The Liberals were the ones to sign Kyoto and agree to an emissions cut of 6% below 1990 levels. Instead, as of 2006, they were 22% above.

The recommended emissions target for developed nations is a 25-40% cut from 1990 levels by 2020. Most developed nations have stepped up to the plate. Norway has pledged a 40% reduction. Japan has pledged 25%. Australia has agreed to 5-24%, depending on whether there is an agreement at Copenhagen. The EU will cut 20% no matter what, and will increase this to 30% with an international agreement. Britain has increased this even further, with a 34% pledge.

The US is a little trickier. Waxman-Markey will cut 14-20%, but from 2005 levels, not 1990. Does anyone know how to convert this so we can properly compare it to other countries?

Then there’s Canada. Canada has pledged 3% from 1990 levels. Absolutely pitiful. Depending on what the US conversion turns out to be, there’s a good chance that our humble country is the worst in the world for climate change action and leadership.

The government knows this, and they’re spending a great deal of time and energy trying to cover it up. For example, they won’t say “3% by 1990”, because it’s so obviously pitiful. Instead, they say that they’ve pledged “a 20% cut by 2020″…..from 2006 levels. What is the point of deviating from the standard baseline among countries who signed Kyoto, unless you’re deliberately trying to keep your citizens happy with you?

And that’s not all. In the summer, I wrote about how Canada was still advertising its Turning the Corner plan, even though it appeared to have abandoned it. When I went to PowerShift in October, I had the chance to talk to a lot of people who knew a lot about Canada’s climate change policies. And yes, our government has definitely abandoned Turning the Corner. But it’s still one of the first links in their sidebar. And when you click on that link, you discover that it hasn’t been updated since August 2o08, and the legislation is supposed to come into effect in January 2010. Yet another example of keeping the citizens happy without having to do anything.

Stephen Harper’s climate change website is full of talk about emissions intensity and CSS. There are pictures of him shaking hands with Obama and planting trees. But trying to get any real information out of it is next to impossible.

The government is spending so much time trying to convince Canadians that they’re taking bold action on climate change. They’re devoting so much energy to putting on sustainable masks that contradict all their talk of a transparent government. All without having to take any action at all.

What I ask is, why not spend all that time and energy actually doing something? Why not cooperate with other nations and realize that this is the way the world economy is going? Why not be proactive and prepared instead of hoping that the whole issue will just go away?

It actually makes me ashamed to be Canadian. Ashamed to be part of this country that tosses around the future of our civilization, the future of my generation, so lightly. And for what?

Where to Go for Answers

To all of our new readers, thanks to CBC and StumbleUpon, this is for you!

Most of us don’t read scientific journals. We read the newspaper instead. We read our news feeds. We watch CNN.

These sources, as we know, are fairly low on the credibility spectrum. But how are people like you and I supposed to understand the more credible sources? Scientists don’t seem to speak plain English. And you can’t even read most of their studies without a subscription.

Usually this isn’t much of a problem, because the popular press and the scientific journals say basically the same things – that there’s going to be a lunar eclipse on a certain date, that red meat increases your risk of a heart attack, that a new kind of dinosaur was just discovered.

However, when you start reading about climate change, the newspapers start going crazy.

The world is warming. The warming is caused from the world coming out of an ice age. The warming stopped in 1998. Glaciers are melting. The warming is caused by human activity. The warming is caused by sunspots. The warming is inconsequential. The warming is catastrophic and is going to kill us all. New York is going to be underwater. Scientists faked the whole thing.

As someone who keeps up-to-date with the scientific literature – that is, sources from the top few tiers of the credibility spectrum – I can tell you that it is not under the same confusion as the mass media. There are a lot of myths about climate change that go around the newspapers and the Internet, but were never in any sort of legitimate scientific study. I cannot stress this point enough.

For example, have you heard the one about NASA getting the Y2K bug, and later discovering that the warmest year on record wasn’t 1998, but in fact – whoops – 1934? Global warming must be fake!

Actually, that’s not correct at all. NASA discovered that 1934 was the warmest year on record in the United States. And that “United States” part got dropped in translation somewhere in the blogosphere. Contrary to what American media would have you believe, the United States is not the whole world. It makes up less than 2% of the Earth’s surface. And the warmest year on record globally is either 1998 or 2005, depending on how you measure the Arctic temperatures.

There are dozens of stories like that. So many of the explanations you hear for global warming being natural/nonexistent/a global conspiracy are based on misconceptions, miscommunications, discredited data, or flat-out lies. They were never in the scientific literature. They are not endorsed by the sources at the top of our credibility spectrum. They are, shall we say, urban myths.

But how are we, humble non-scientists, scanning through the newspaper on the way to work each morning, supposed to know that? We need some kind of a link between the scientists and the public. Some journalist who actually knows what they’re talking about, and cites all of their claims with credible sources. Some sort of encyclopedia that will dispel all the myths about climate change.

Luckily, there are many of these encyclopedias. There are a lot of people out there trying to fulfill this very purpose.

One of my favourites is Peter Sinclair’s Climate Denial Crock of the Week video series on YouTube. He debunks common claims like “global warming stopped in 1998”, “global warming is caused by the sun”, and “temperature leads CO2 in the ice cores”. Sinclair is a professional journalist, so all of the videos are well explained, easy to understand, and fun to watch.

Another great source is Coby Beck’s How to Talk to a Climate Skeptic series. These articles cover just about every objection out there. Equally comprehensive is Skeptical Science. They’ve even compressed their explanations into “sound bites”, so you can answer your uncle’s objections in just a few sentences over Thanksgiving dinner.

Some of the sources from the top of our credibility spectrum have also chimed in. Environment Canada has created a fantastic FAQ document about climate change. It covers everything you need to know to wade through YouTube comments or online debates, along with citations you can actually trust.

Finally, Scott Mandia, a regular reader here at ClimateSight and a meteorology professor in New York, has just posted a copy of his presentation to the public about climate change. What I like about this document is that it’s very up-to-date. All of the graphs are the most recent of their kind. It also provides some philosophical perspectives to really sink your teeth into, like an analogy about medical advice, and some memorable quotes at the end.

We shouldn’t have to double-check everything the newspaper says about climate change. But the objections to anthropogenic global warming have such an awful track record that we really should, at least before we go and spread them around. These sources will cover just about everything you need to know.

Very Scary Stuff

One of the most worrying positive feedbacks of our current climate change lies deep in the Arctic permafrost and the ocean – methane hydrates. Methane loosely bonds to water, which freezes and lies stable…..until it melts. When it gets warm enough, the methane breaks apart from the water and is released into the atmosphere, or is dissolved in the ocean and then slowly released.

There is an enormous amount of methane in the form of hydrates up north – using its GWP, enough to “double” the amount of CO2 (even if it doesn’t all convert to CO2), if I remember correctly. This feedback is not included in climate models, as nobody really knows when or at what point huge amounts of methane could be released.

Unfortunately, we have evidence that it’s starting to begin. CORDIS and BBC report that a study in Geophysical Research Letters has discovered methane plumes rising from the ocean floor. Right now the methane is dissolving in the water, but we don’t know whether or when it’ll reach the atmosphere. Even if the methane stays dissolved, the acidity of the ocean will increase, which can damage marine life. Even if this begins as only an impact, not a feedback, the Arctic is stressed out enough as it is.

I didn’t expect to hear news like this for quite a few years. As one of the authors says, “Our survey was designed to work out how much methane might be released by future ocean warming; we did not expect to discover such strong evidence that this process has already started.”

Reminds you a bit of Larsen-B, doesn’t it?

Nobody Knows What’s Happening

About a year ago, the Canadian Conservative government announced that it had a plan to cut Canada’s greenhouse gas emissions 20% from 2006 levels by 2020. The new regulations were scheduled to come into force on January 1, 2010. I was pretty happy – skeptical of Stephen Harper’s ability to carry this out, and wishing it was an even greater reduction – but still happy that progress was being made.

A few months ago, there was one article buried deep in my local newspaper that announced that the Harper government was giving up on this plan. They didn’t want to hurt the economy, or trade with the States, or something like that, so they were going to wait until the Waxman-Markey legislation was fully implemented. That meant they wouldn’t do anything on the issue until 2012, and even then it would take until 2016 for the laws they’d agreed on to come into force. I recall one interviewee in the newspaper saying that it was pretty ridiculous for a prime minister these days to expect to take no action on climate change for his first 6 years in office – and expect to get away with it.

These sort of political decisions usually make their way through the Globe and Mail, CBC, Rick Mercer, and Maclean’s pretty quickly. But this time, I only read the one, half-hidden article, and despite an extensive search, couldn’t find any other mention of it. I was amazed.

As I mention Canada’s (in)action on climate change in a (hopefully soon to come) video I’m working on, I wanted to make sure I had my facts straight. So I went through the Environment Canada website, which, believe me, is not an easy task. Every time I clicked on a link that said “action” or “Canada’s action plan” it lead me to a page that said “Copenhagen is coming!”

Eventually I found the page that described the 20% by 2020 plan – “Turning the Corner”. It hadn’t been updated in over a year – the last announcement was from August 9, 2008. There was no mention if the plan had been abandoned or postponed. And yet it still said,

“Proposed greenhouse gas regulations are expected to be published in the Canada Gazette later this year, and the regulations finalized in 2009 to come into force as planned on January 1, 2010.”

So they hadn’t done anything on this plan for a year, but were still claiming that it would come into force in four months, all the while making no admission of its abandonment and hoping nobody would notice.

I asked a coworker, who had been just as confused as I was. We called the help number at the bottom of  the page, which, unfortunately, was the central information line for all of the Government of Canada. The employee who answered seemed to know even less than we did regarding Canada’s climate change plans.

“I can’t find anything,” he said. “What’s the name of the report?”

“Turning the Corner,” we replied.

“Okay. Just hang on while I type that into Google.”

Eventually we were sent to another federal website (which is so hidden that I can’t even find it again) which apparently dealt with greenhouse gases. It turns out that all they did was measure Canada’s emissions, and require any industrial plants that surpassed a certain amount to report this to the government – but not have to reduce them. Nowhere was there mention of Turning the Corner or any other kinds of regulations.

The environment section of Harper’s website was even worse. Words like “emissions intensity”, “clean air”, “home energy efficiency”, and “environmental leadership” were tossed around, assuming that nobody would read between the lines to discover how little Harper was actually doing about climate change.

The government employee on the line also gave us the number of the Environment Canada deparment. We called them and were given the number of the secretariat for greenhouse gas management. We called that number and got the answering machine. It was 2:00 PM on a Monday. We’ve never heard back.

Does anybody in Canada actually know what’s going on with climate change? Why isn’t anyone demanding answers? Is our country really so apathetic one way or the other?

At least in the States there’s a major opposition to cap-and-trade, so the government can’t pull the wool over your eyes too easily. At least it’s a controversy which is visible to the public

If any Canadian readers actually know what’s happening, or have any more information, please leave comments – this is far too important to ignore.

The Greenhouse Effect

It always helps to have some background scientific knowledge on climate change – it makes it easier to sort credibility and call people’s bluffs. I thought I’d give a brief explanation of the Earth’s energy balance, something that confused me for a long time.

All substances can absorb a certain amount of radiation – they must then emit or radiate it back out, usually in the form of long-wave radiation (heat). Some molecules, however, possess certain chemical properties which allow them to absorb (and therefore emit) an extremely large amount of radiation relative to their size. These molecules are called greenhouse gases. I recently asked a chem major exactly which properties determined this amount of absorption. They replied, “You don’t know enough quantum chemistry yet.”

When solar radiation, in the form of short-wave radiation (light), approaches our atmosphere, about 30% is reflected right off. The remaining 70% reaches the atmosphere and the Earth’s surface.

The surface of the Earth absorbs some of the radiation. It can’t hold onto this energy indefinitely (it wants to have room to absorb the next rays of light), so it emits it back out. Even though it received the radiation in the form of light, it emits it in the form of heat. It is this emission that determines the temperature of the Earth.

Greenhouse gases allow short-wave light to pass straight through the atmosphere, but they do absorb some of the long-wave heat that the Earth just emitted. The more greenhouse gases present, the more radiation the atmosphere, as a whole, can absorb. When atmospheric particles (greenhouse gases, in this case) emit this radiation back out, it goes uniformly in all directions. Some goes up and escapes out to space. But some goes down and hits the Earth’s surface again.

Therefore, the Earth has to absorb and emit some of the radiation twice. This increases the temperature of the Earth.
