But if youve covered even more land with people, buildings and removed trees then plants cant increase can they?
" An estimated 18 million acres (7.3 million hectares) of forest, which is roughly the size of the country of Panama, are lost each year, according to the United Nations' Food and Agriculture Organization (FAO)"

Common sense tells me that due to population growth, industrialisation, pollution over a short space of time theres going to be an effect. Forget anybodies facts or statistics its simple logic. Our weather is less predictable, theres measurable change.
I didn't say the amount of plants would increase, just the rate at which they grow, and hence the amount of CO2 they take from the air and replace with oxygen.
I agree with you that we should be doing more about deforestation and people pouring toxic chemicals into the rivers and oceans as well. I don't want to live in a dirty, polluted planet any more than you do.
I also agree with you that we are without doubt adding CO2 and other gases into the atmosphere.
Where i do disagree however, is that just because we've had a few droughts or stormy winters etc etc over the last few years, that that amounts to any kind of evidence that we are influencing the weather/climate. Considering the earth is 4.54billion years old, the time frame you mention is just too small to prove anything, it could easily be a statistical blip.
Most of europe was covered by ice 20,000 years ago, then it all melted. That climate change certainly wasn't caused by us, so even if the climate is warming slightly and it's not a statistical blip, then it could well be caused by natural phenomenon anyway.
If someone can show me convincing evidence that we are changing the climate, then i will believe it. Someones "common sense" or some climate change scientists "computer model" proves nothing in terms of actual evidence.
Computers are just big calculators, the answer you get depends completely on the data you feed into them. I could write you a program that says the climate is going to cool by 50C next year or that the sun orbits the earth if you wanted me too... only long term statistical evidence will convince me that any climate change is man-made.
