I don't want to discuss cause and effect; it's quite late for that. What is essential is to find a solution and to move on. For instance, what do we make of it "IF the ice caps melt "and all that fresh ice water goes into the ocean currents near the poles? Do you really think the currents will drop temperature? Or will we get more evaporation causing more cloud cover and heavier rain and storms? Will the water levels rise a massive amount in a short space of time? Will the planet self regulate and we are panicking over nothing? Will the planet heat up and destroy our environment? To my mind, it is obvious that global warming is a reality. The key question is wether this is due to natural causes or to human activity.
Watch this video and think about it.
After watching this video, there seems little doubt that this recent, deep rise in temperatures is due to human beings. Moreover, it's very clear that hadn't it been by our own actions, there would have been found less temperature changes. I completely agree with Richard Attenborough when he explains that the variations in "the climate are enduced by human activity". A group of climate scientists prepared a graph in which they explain the process. Up to the 1970s the variations of the climate can be explained by natural causes. However, from this decade on what causes these variations is the human factor.
Nevertheless, who is really to blame for global warming? That's another key question to which I'll try to give an answer in my next entry.
