We have to make seed banks, a global archive for the future, and we have to move our power plants, in order to maintain a functioning society. We have to start lining the trash dumps that line our shores, we have to start preparing for inundation. Remember, the last time carbon dioxide levels were the same as they are today, the ocean was one hundred feet higher.”
