This post only defines how to make it a threat.You will need to cover what the Scientist say and write about it. Items to cover: coastal invasion by the oceans and also related erosion. You need to note that most of the world's major cities will be affected by this coastal invasion. With more energy available storms become more severe, we now have examples. Climate change: hotter summers, milder winters. Crop growing will need to change as the corn belt moves north. Prevention of climate change will involve major changes in living, working, energy consumption. You should note that the world's people are mostly resisting this or in denial. I feel change in what people do the prevent climate change will come too late.
I knew that as a kid more than half a century ago, all this high tec data is just finding out now ?A good topic can be regarding the latest discovery of the fact that climate changes are now permanent. integrating multiple studies, it has now been found that there is no way climatic changes can be reversed in any way.
