"We’ll never know who it was that bore the burden of climate change."

What? So there is a possibility that no one will bore a burden of climate change? I though America was mostly responsible, because of our life style. And Hurricanes are natural events that happen this time of the year. So wouldn't climate change, change the time of year Hurricanes form? This is like winter, it happens during certain times of the year, and climate change doesn't seem to change that.
