I knew a kid in highschool who drank 2 liters of coca cola every day.
he got headaches when he didn't drink at least 1 liter.


I wonder if he never drank anything else? I had friends who used to drink only pop or milk, never water or juice. They weren't very healthy. Most of them have gotten over their aversion to H2o.

Some say the human footprint is too small to account for a significant change in global climate and carbon increase, while other scientists claim human activity makes up the majority of carbon emissions.

The "climate debate" may be framed in these terms, but this is a repetition of a false dichotomy. I have to draw on some numbers to illustrate this point:

While human activity only releases 5% as much CO2 as earth’s systems circulate, 57% of our emissions are beyond what can be absorbed by the ocean surface and by plants. The result is a 0.5% increase in atmospheric CO2 levels each and every year.

So, while human activity is not the dominant source of CO2, it is the largest variable source, making it the primary driver of climate change. The same argument applies for land use changes even more so.

The rise in C02 isn't created solely by human activity.

There's a debate going on right now as to whether humans cause the majority of the increased carbon in the atmosphere, or whether natural causes (such as volcanoes, vegetation, etc.) are to blame. Some say the human footprint is too small to account for a significant change in global climate and carbon increase, while other scientists claim human activity makes up the majority of carbon emissions.

Who to believe? It truly is a frustrating scientific debate, and if we are responsible for the majority of carbon emissions in this world, I'd be the first person to embrace a "green" change. Until then, it's discouraging to see self-righteous greenies pushing their agenda as being conclusive.

remind me to promote your human footprint video.

long - this was a really good show - but I think some of those numbers are REALLY off.
I know I don't drink 30 cans of soda a month.


They use averages.

Bartlett has a poor understanding of population dynamics, S-curves, carrying capacity, and a raft of other important models. His power laws are simply bad science.

That said, he's certainly right that people don't understand how population growth and economic growth multiply to create today's overwhelmingly large human footprint.
