Yeah okay, but all of that global warming stuff aside, if you're riding your bike to work, that's one less car spewing pollutants into the air during every morning and evening rush hour. Period.

Edit: Ah! I didn't see the above post. Never mind...

I chose the last option... it's either that, or bumming rides or catching the bus.

I also do it for my health. It's the only excersize I get! If it weren't for my bike, I wouldn't move around much.

I take my bike over public transportation. Trimet really isn't that bad, but the fact that I have to transfer onto 3 busses, not to mention it takes about 1hr 15min to get to work and 1hr 30min to get home. My workplace is about 9 miles away from home, and I usually commute five days a week. It takes me about 35-40 minutes each way, depending on traffic.

I've noticed that my attitude is different when I'm commuting to and from work. I seem to be a little more uptight compared to when I bike around on the weekends. I've also concluded that the fact that my job makes me feel kinda s***ty doesn't help, either. Ugh... anybody know of job openings in PDX? I will (pretty much am, too) work for peanuts.

I know what you mean by the bus being slow. I used to commute from Beaverton to downtown Portland, about a 10 mile commute. One day I broke a spoke and was forced to take the bus the rest of the way into town. What was a 20 minute trip on my bike (from where I broke down) turned into probably about 40 minutes on the bus.

I did an atmospheric science degree at the UoGuelph. The study that you state refers to supposed inaccuracies in a study of tree-rings in bristlecone pines. The climate change theory is not adressed in the URL you provide. And anyone contesting a positive correlation between global temperature and atmospheric CO2 levels was in a tiny minority at the UoG. Tiny enough I never heard of them.

The only correlation I have noticed is scientists who contest the climate change theory tend to get their funding from the petroleum industry. But that's just an observation.

And for the record, you "debunk" a theory based on errors. You dont 'debunk' errors... you just identify them.

Life's too hectic to have time for the Gym, so a 50km round commute 2-3 times a week provides the exercise I've been missing for years. Using secondary roads/cycle lanes it takes no longer than driving to work & is a real stress buster. Saving $$ in petrol helps justify bike parts & upgrades..
