Hoax.

Any of you heard of the Gaia Hypothesis?

its obviously a huge problem. and i dont think people will truly start worrying until its too late. i think governments are too caught up in over things, though there have been some positive changes in the UK such as recycling on large scale, and ive started to notice people with solar panels on their homes. but really, i think if we are going to stop then everyone needs to do their part, and a lot of countries dont.

its true that the earth does go through these cycles, and if i remember correctly, my college geography teacher showed us that the levels of carbon dioxide, or whatever greenhouse gas it is, has never been so high before as in natural times. there was even a question on it on my exam, and you can't deny that humans havent had a
large impact.

It doesn't matter how "good" the measurements were back then. Climatologists can measure the climate hundreds of thousands of year ago by analyzing ice core samples. That's how we are able to know what the temperatures and CO2 concentrations were 100,000 years ago.
