Jeff your sample period is too short to confirm global warming. We have just exceeded our hottest spell recorded since 1935 I assume that global warming rose and fell between then and now. Old fences on the Coorong and river Murray are being exposed due to global warming, I assume that the fencing contractors used submarines 50 years ago. The credibility of scientists should be seriously questioned now, the money and fame goes with being on the warming bandwagon which gets all the press. There is no difinative proof about global warming but I can plant some trees for you ( for a fee ) to offset your computer use, what a crock of sh&*%$^
