B. Structural difficulties
1. We are doing too little
Here is what scientists are telling us:
■Glaciers are shrinking.
■The Artic ice cap is disappearing.
■The sea level is rising.
■The cycles of evaporation and precipitation are intensifying.
■Species are becoming extinct at faster and faster rates.
■Rising CO2 levels are acidifying the oceans, killing coral, shelfish, plankton and disrupting the whole marine food chain.
■Huge amounts of methane – now frozen undersea or in the Artic permafrost – could be released into the atmosphere; and methane has 25 times as much greenhouse effect potential as CO2.
■Science predicts that if nothing changes, global warming will create hundreds of millions of climate refugees by the end of the century. Where will they go?
■A larger number of extreme weather events will exacerbate food, water and energy scarcities; this will bring different groups into competition over dwindling resources and land, potentially turning fragile states into failed states.
We know that in order to curb these worrysome trends, we need radical change.
