You will need a filter system if you use drip lines.They can clog easily with pond water.

Millions of years ago there was a period of time when earth went through a "hothouse" climate phase.No ice was present at the poles and life struggles to survive. Plus there are a number of times in the climate past where the planets temperature were way above what we have seen in the 20th century. Gore is way off.

I agree that there is a mild warming trend.A trend that is slowing down in recent years. I do not agree that atmospheric CO2 is the main driver of the warming. I think the sun is the main driver of the mild warming trend. I do not think using GCM's for long into the future climatic projections makes for valid science.It can not be testable. Cheers
