MrArboc said:Very, very few people deny that global warming is taking place since we just have to look at the figures to see that it is happening. What people are debating is if we humans (and cows farts) are making the changes greater and faster than what's normal.
Global climate change in that case. Weather is the temperature, humidity, rainfall etc at a given time - the weather is always changing from one hour to the next. Climate is the weather over a long period of time, say 10-50-100-1000 years.
I can actually see the global warming happening - believe it or not. Our winter (=period with snow) is about 4-6 weeks shorter now compared to 20 years ago but that doesn't mean that the summers are always warmer. The fact that the average temperature on the globe is higher does not mean that we all get warmer weather Here we'll probably get a colder climate due to the global warming since tha changes will affect the North Atlantic Drift. In a hundred years we might be where Alaska was in the 1800's.
Most of these models don't take into account solar output or the role of water vapor or other gases in the atmosphere. As a matter of fact, the biosphere is booming and most plants (excepting my peppers, it seems) are loving more CO2 in the atmosphere. There are more forests now in North American and Europe than there were 100 years ago. Also, there were periods where CO2 was exponentially higher than today. I also think that the role of volcanism is ignored too much.
Our winter was very long and cold, and apparently it hasn't really ended yet.
If they want to blame someone, blame the Asians for their terrible pollution, and what about Brazil? They are the ones cutting the rain forest down.
