Differing Effects of Climate Change

Recent studies on the change in climate have shown that the effects on different ecosystems is not consistent at all.  Specifically changes that enrich oceans with nutrients and make better ecosystems have a negative effect on trees and result in less rain.  Bryan Black from the uNiversity of Texas has lead he research looking into tree rings from the last 600 years and looked at the results of different climates and climate changes.  What he has fond is that during times of healthy booming oceans full of life and nutrients, tree populations have shown slow growth, indicating drought or disease.  Upwelling is an essential and natural phenomenon that bring cold nutrient rich water, but this may have an adverse effect on trees.
