Study links human-lnduced climate change to flooding

The researchers from Botswana, South Africa, and the United States who undertook the study say the floods which reached levels last observed 20-30 years ago coincided with similar damaging disasters elsewhere, thus motivating them to assess the impact of climate change on the floods.

They used two climate models to predict how floods would change under two different climatic conditions — one with greenhouse gases resulting from climate change and the other without the gases. According to the study published in the Journal of Hydrology on April 16, human activities increased the amount of greenhouse gases in the atmosphere leading to the planet warming over the past century, thus affecting the Okavango.
