In modern environmental discussions, nary 5 seconds goes by before someone brings up the issue of “Global Warming”. I’ll spare you the definition and the details, but I’ll look at a few common arguments on both sides:
“Global warming caused by humans”
- Carbon dioxide levels are higher than they’ve ever been, causing the earth to warm much in the same way Venus does.
- The CO2 output of humans is vast.
- The earth is getting measurably warmer.
- Ice caps are melting.
- No, seriously, the earth is heating up.
“Global Warming Not Caused By Humans (also Global Warming Doesn’t Exist)”
- The earth has a long history of heating and cooling on its own.
- The scientific consensus in the 1960s was that the earth was cooling.
- Solar activity varies.
- The data itself is invalid.
- We’re not the only producers of carbon dioxide.
Both of these sides might actually be right. From the uninformed standpoint, it might as well be a coin-toss. Unfortunately, it seems that many people settle the decision much in this very manner.
How did people come across their opinions? Where did they get the information for it?

Media White Lies
Most people get all of their information on scientific research from the news media. The goal of the media is to explain issues for the lowest common denominator in society. If the average 14 year old can’t understand the news, it still needs to be simplified.
Like a parent explaining science to a toddler, the media can’t directly report the full text and results of environmental studies. So they do what the parent does: they tell little white lies and simplify the matter. For the most part, that’s fine. For most scientific results, people don’t need to know the methodology, the exact data, or the statistics that were used to come to a conclusion. The only thing that they need to be aware of is the result of the study. When I hear of a diplomatic summit, I don’t need to hear about the seating chart, the day-by-day discussions, or various faux pas. All I need to know about is what happened.
What complicates this matter is the fact that this is an issue where people are taking very strong, very opinionated sides. The worst part of it is that they aren’t even taking the sides based on the information: they are taking sides based on media reporting of the information. This is made worse when curious people find out extra information on their own (“You mean to tell me the earth heats and cools on its own?”).
I don’t know about you, but my only understanding of the global warming debate comes from media reports, An Inconvenient Truth, and a small sampling of scientific papers on the subject. I am not an environmental scientist, and environmental scientists aren’t interpreting the data for me. The only explanation I am getting is from the media, which is giving me a simplified version of global warming research.
So Where Do You Stand?
What position do I have on the “Global Warming Debate”? I don’t have a position! I clearly don’t have the right information to make an informed decision on the subject, and fortunately, that’s enough to stop me from forming an opinion.
Your opinions should be formed as a conclusion from sound premises. The average citizen is not informed enough to make a sound decision on global warming, so they should not. As wonderful as it’d be for you to be able to hold your own in a discussion against climate scientists, I’d bet that it isn’t very likely.
So what issue should we be debating?
Humans have a long and provable negative effect on our local environment. Countless animal species have gone extinct. We create gigantic landfills of non-decomposable waste. We’ve spilled oil over vast swaths of land. Our cars create smog. We cause acid rain. Factory emissions travel and land on citizens downwind. We caught a damned river on fire. Rivers are made of water and are therefore supposedly inflammable, but human ingenuity knows no bounds!
So What Should I Think?
[ad#babeled-ad-medium-square]
It doesn’t particularly matter what your side is, so long as you’re basing it on what you know to be fact. If you think that it’s OK for other humans to suck on your exhaust pipe because you’re not morally responsible for the well-being of others, great. If you think that factories should minimize their exhaust output so that it doesn’t go into your lungs, awesome. If you think that humans should conserve as much as possible so that the species could potentially last indefinitely, scream it from the mountaintops.
The environment is more complicated than what happens on the global level. The average American is probably better informed on the effects of humans on local and regional levels, so that is the level at which they should try to form opinions.
If you feel the need to frame the debate in a simple name, call it “The pollution debate”. It even has less syllables, and gets straight to one of the roots of the issue.
For Fun
The next time you see somebody say they don’t believe global warming is human-caused, say “Which isn’t to say we should try to pollute or destroy our environment”. Sometimes you find that the person is strongly on the pro-pollution side, but every now and then you catch someone in a priceless moral quandary.
