Climate change and the subsequent impacts are a global problem. The solution will undoubtedly have to be a global fix that requires every nation, rich and poor, to change its behaviors to mitigate risks. Will it be expensive? Absolutely. But the cost of inaction is greater in terms of the loss of life, the loss of tangible items, and the sustainability of humanity. The solution is something the entire international community should get behind.
Not only are the wealthy countries the cause of the worst impacts brought by climate change but they also refuse to support those that need it the most financially. The EU is putting more onus on India and China in this draft, with the intent of causing rifts among developing nations. The most impoverished countries have every right to be frustrated with these machinations and delays.
