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.
