If car air pollution is what causes global warming, then how come there was no global warming in the 1960's when cars were polluting the air way worse than now? Car technology is way better than it was back then.


------------------------------ I've also heard that global warming isn't really happening. Yes, the average tempature of the earth has risen, but not by very much. I heard that in the last century, the average tempature of the earth has risen and fallen. Right now, the average tempature is about two degrees higher than it was 100 years ago. What do you say about that?

Barry's Response - Alex: Good point. Here's a few supplemental thoughts on car air pollution and global warming.

1) Less pollution per car, but more cars, way more. Also, lots more driving per car.

2) Cars are a major but not the only source. We have way more industry and other types of pollution around the world than before. We also have natural sources, but one can probably assume that the magnitude of their contributions remains relatively fixed over a long time scale.

3) There was greenhouse effect all the time, but global cooling was the concern way back then. Obviously there are forces greater than pollution affecting climate.

by: Nicky Parker

I completely agree to the points mentioned here. Cars of these days are fully advanced and are causing less pollution than that of the earlier days. I appreciate the work of researchers. Yet we have not stop polluting air by using cars but have minimized it up-to some days. But I hope, days are not far when we can use pollution free cars. Smart cars, hybrid cars and solar cars are the steps towards this future. Presently a well maintained vehicle is the key to reduce air pollution. Thanks for sharing such a good discussion.

More People, More Cars, More Miles Driven all adding up with out the clean up. I live in a 1920's home, When it was first built they white washed it and again every year untill the mid 30's then every couple years it got painted in lead based until the 70's when every few years it got latex. When we replaced a window last year we found a sturdy 1/2" layer of paint and between it was rotten wood. Global Warming is like that!

by: Adam

It sounded like a stubborn Person that is refusing to acknowledge that global warming is true, global warming is not a myth. This time around the summers were too Hot, and Winters too Cold its all cause of the Global Warming, Global Warming is something that doesnt happen in Few days, it took its time and even though Cars are less Poluting now, that doesnt help it. Just read the article like "Why is Global Warming Unstoppable and Unavoidable" which are intresting to know. Just check the info about Global Warming on this site it will open your eyes.

1. My first impression o this article is that it isn't bogged down with a lot of boring info like most articles on global warming. 2. The article is intersting because this is an important current event that everyone seems to be discussing no. 3. This article has inspired me to explore this site further. 4. I would like to know more about how the earths air quality affects the wildlife on our planet and what can each individual do to help.

Interesting opinion. I thought you sounded just like those stubborn people that refuse to acknowledge that global warming is true, but you do have some valid points. Many people feel that global warming is just a myth, but that shouldn't stop people from being more careful about our habits and how it's affecting the environment. Sure, there wasn't as big of a problem with global warming when cars were just made, but remember it wasn't like they were driving a whole lot when many of the highways/freeways and gas guzzling Hummers and SUVs weren't around at the time. Also, like what Barry said, there are also a lot more factor going into global warming than just cars. Good article and opinion though.
