Flood Alert

Introduction

By 2100 global warming will boost the frequency of extreme flood events in 42 per cent of the earth’s land, including humid areas of India, Southeast Asia and Africa. Flood incidence is, however, projected to decrease in most of Europe except the UK and northern France. This is the conclusion of a comparative analysis of 11 models for the impacts of greenhouse gas emissions on 29 river basins across the globe. The analysis shows that if warming progresses without effective countermeasures, many of the world’s 29 major rivers would see massive floods, which currently occur once a century, at an increased frequency of every 10 to 50 years.
