The very vocal deniers (the 3%) love to bash anything that has to do with the environment. Science says they are wrong. Whatever we can do to make the planet more livable I am all for, (its the only one we have. But lets say for the sake of argument, if they are right then the planet will persevere and water levels will not rise and global temperatures will will moderate. But if they are wrong, (which they are) then by the fact we have not done anything means that we as a civilization are doomed. I would prefer to err on the side of caution. I want my kids and grandkids to be left with a healthy place to live.
