climate change is a part of the planets cycles, its been hotter before now, it will be again, huge tree stumps reappearing from under receding ice sheets prove this, all we can do is minimise our impact on this, it is useless to think we can change it. for example 50 million years ago the average temperature was 14 deg c hotter than today, its all well and good people showing graphs of temperature rise over the last 100 years, but , thats just an eye blink in geological time, we are only just getting to temperatures last seen 2 million years back, which were dropping back down at that time. climate change is nothing new, in reality its as old as the planet
