This is just what a number of responsible scientist's, as opposed to scaremongers have been saying. mans efforts have very little effect on temperature other than on a purely local level, ie cities being warmer than the countryside.Also dont forget one of the major requirements for plant growth is the cardon di-oxide in the atmosphere, and one of the limiting factors has in the past been lack of CO2. And if we are entering a cooling period perhaps we should all be encouraged to generate more greenhouse gases to try and keep the planet warm. I am still convinced that gw has and is a bogeyman utilised for specilialsed interests, ie taxation and control
I wish they'd make their mind up. One minute (or decade anyway) they are saying the poles are melting and its getting warmer and it does seem to me to be the case. And now some scientist (and I notice theres only one person saying this so far) says that its going to get colder.
So whos right? Do we stop up on bathing costumes and sun block or thermal underwear?
Part of the problem is the issue of how global warming will manifest itself. there is a body of thought which talks in terms of global warming leading to what we see now, ie meltdown in the polar regions but it leading to another ice age.
The reason is the north Atlantic conveyor or the gulf stream as it is usually known. Once the colder waters come down from the Arctic though polar melting some scientists think (as has happened before) the conveyor is lowed to a stop. the warming effect ceases and we have another ice age.
