Global warming is worse than even environmentalists had imagined a few years ago. The alarming news is that all over artic regions the permafrost is melting. Permafrost is defined as anything that has been frozen for two years or longer. Now permafrost that has been around for 1000s of years is melting. The problem is that permafrost contains organic matter that freezes CO2 gases, presenting a greenhouse gas time bomb; once warming reaches a certain level it begins to feed into a viscious loop: more permafrost melts, more CO2 is released, more warming occurs and so on. Climatologist generally refer this as the Tipping Point
Climate change is here to stay. The argument about whether or not it exists is a needless exercise. We need to accept its reality and plan accordingly. Know this: whatever we do now will not reverse the effects. The carrying capacity of all nations will be affected within the next ten to twenty years as more land becomes unusable. Who gets to live where under what conditions will be a political mess we do not have the tools for. So yes, IT IS all about equality, human rights and general fairness.
But don't take my word for it. Here are links that illustrate the issue better than I ever can:
