      Hot potato!!

      The scientific evidence is that we caused it – this is now almost overwhelming evidence. I can accept though that maybe some of the warming could be associated with warming cycles, but we are definately making it worse.

      While the Earth has always gone through periodic warming and cooling, the speed of those cycles has involved at least 10’s of thousands if not 100’s of thousands of year. Global warming is happening over a period of 100 years and the ecosystems simply cannot respond fast enough to cope. No – this is definitely mankind’s doing and it is up to mankind – us, all of us – to do something about it.

      Unfortunately … it’s us that did it! But if we had the power to do it then hopefully we have the power to stop it and maybe even reverse it …

      I believe it is caused by us since its effect is much more rapid and dominant compared to other natural progression …. so basically agree with the other scientists here 😉
