simultaneous droughts, famines, epidemics: scientists
Research published by US National Academy of Sciences warns climate change impacts could be worse than thought
Europe, North America at risk
"... uncertainty arising from the impact models is considerable, and larger than that from the climate models. In a low probability-high impact worst-case assessment, almost the whole inhabited world is at risk for multisectoral pressures."
"This worst case is rather extreme, but nonetheless it represents the upper end of the risk spectrum in light of the large uncertainties."
Chronic water scarcity
"... will confront an additional approximate 15% of the global population with a severe decrease in water resources and will increase the number of people living under absolute water scarcity (<500m3 per capita per year) by another 40% (according to some models, more than 100%) compared with the effect of population growth alone."
"There is an elephant in the room: current and future climate change impacts. But strangely, many people seem to be blind to it. Many decision makers prefer to turn a blind eye to global warming consequences, while many scientists tend to focus on very specific aspects of climate change. So we resemble the fabled blind men, who unknowingly touch different parts of the same elephant: grasping the animal's trunk, one of the men is convinced he has a snake in his hand, whilst one other mistakes the tail for a rope. To recognize the animal, they must talk to each other to properly identify the individual parts and to bring them together. This is exactly what this international project does."
