Global warming and ice ages.Watch
The fact of the matter is that greenhouse gases do cause a rise in temperature, humans are currently producing excessive amounts of these gases into the atmosphere.
As well as bringing carbon into the carbon cycle which would have been on the side lines for quite some time (fossil fuels) we are also removing forests which help to reduce CO2 levels. Cellular respiration and photosynthesis pretty much balance each other out, but we are currently removing some sources of photosynthesis.
In short, these gases will cause heat to be reflected and that includes reflection back to earth, rising the temperature. Given that a large amount of these gases are from human activities then how can anyone argue that man isn't at the very least partially responsible. It baffles me.
- reducing energy wastage
- improving energy efficiency
- diversifying energy production sources
- finding energy sources that don't rely on a finite resource
If you don't believe the science - fine, whatever, some people believe in fairies.
If you use that belief to argue against the sensible measures listed above - then you're doing a massive favour for a few very rich and powerful industries who have a vested interest in keeping control of finite resources to stay rich and powerful.
