Greenhouse effect (in a bottle) explained

Carbon dioxide (CO2) is frequently in the news because its production from burning fossil fuels causes increased levels of the gas in the Earth's atmosphere.

CO2, along with a range of other greenhouse gases, is often implicated in global warming. But what is its role in the greenhouse effect?

Scientist Dr Maggie Aderin-Pocock from EADS Astrium visits the Royal Institution's new Young Scientist Centre to carry out a simple experiment that shows how CO2 traps heat.

The whole lag idea is based on a graph that is inconclusive due to the lack of data on the CO2 side...

Actually there is a "lag" that has been recorded. The theory is co2 increase = increase in termp. Well the problem is co2 has decreased in productions BUT temp keeps increasing.

PV = nRT ...you can increase the temp with any gas if you increase the pressure.

No warming? Really? Might want to check your data again.

No warming for 16 years while atmospheric CO2 steadily rises. The hypothesis is flawed and simply wrong. AGW is a hoax and the so called consensus is nearly as big a hoax based on 79 self proclaimed climate scientists.

I agree regarding pollution, but that is an entirely separate issue. Pollution is not climate change man made or otherwise. More fuel efficient cars lead to more deaths. Road to hell....good intentions and all that.
