Well I must say I have been impressed by the pictures
However it is not sufficient to demostrate that some parameters changed because of pollution
The key question is :
What is their impact on the environment ?
I make a simple examples
If you go through medicine books of some years ago you can see that some parameters which nowdays are considered as normal were supposed to be extremely dangerous at the time
The point is that forcasts are extremely hard when you have to do with complex systems such as human body or environment
A statistical analysis is more reliable in these cases

If the population is steady growing from the middle age and if its impact is so strong than I would expect a steady increasing or decreasing of the temperature
I dont see why hot and cold periods follow one another

all sources are biased...here is a good short clip...about algores latest revised findings...

That last ad was political maneuvering at its worse. Do a little research into who made that ad (hint, they are funded by Exxon, Texaco, and Ford Motors) and what that "Science" magazine they quoted really said.

Even if they got the facts right, their logic is bad: "'They' say too much co2 is bad, but we need co2 to live. Therefore they are trying to kill you."

'They' never said we should remove all the co2 from the world. Just that we need to keep it in balance. How's this logic?

"They say eating too much food is bad, but you need food to live. Therefore you should eat as much food as you possible can. Please eat 4-5 Big Macs every day because, eating is what makes us live." -- (sponsored by McDonald's)

My father collects Popular Mechanics and has some old volumes of 1950´s and there is an article about a possible future ozone hole caused by spray cans, so the people knew that and nobody did something to avoid it.

The climate in the planet is changing more fast than it used to do, but we dont see it because we expect to see hurricanes or big earthquakes in our backyard, but if you pay attention you will see the changes, here on Mexico we had our first in history twister A twister!!!! killed 2 or 3 people I think (before to go to cross the frontier). A twister in America only on USA but not so low near of the Ecuatorial line.
