The most concerning thing about global warming is the change in weather and climate not the rise in water. Northern Canadians might see disappearing arctic ice but Latin Americans see lethal storms and floods. The Europeans see glaciers disappearing, an increase in forest fires and fatal heat waves. Warmer oceans mean bigger hurricanes for us in the southern United States. My point is, it does not matter where you live or 'invest'. The affect is global.
Did you know that 19 of the warmest 20 years on record have been since 1980?
