Centuries of Yellow River Climate

Technical Rating: star
You have been told in countless news stories that increasing greenhouse gases is causing droughts and floods all over the world. World Climate Reports looks at two studies of droughts and floods in the Yellow River area in China. One shows that recent climate trends could probably be attributed to the climate effects of black carbon aerosols and human-induced land cover changes. A second study shows a history of the Yellow River streamflow has decreased significantly but is not yet out of the range of earlier streamflow fluctuations reconstructed for the past several centuries.

Winnipeg River: Better Than Ever
