No need for you to feel "scientifically challenged" anymore; there's an App for nearly everything now. It appears that one of the easiest ways to become a "scientist" (concerned or not, my personal view) is to join the Union of Concerned Scientists (UCS). That group has already millions of members (so it claims) and you are most welcome to join. No experience or other credentials required -- if anything, just a few dollars from your wallet.
Really; I'm not kidding. The UCS is just one of several so-called "widely recognized scientific bodies" that pretend to know what's good for you and everyone else on earth. And it's so easy to join and to become another one of their many "scientists," concerned or not. You can endorse any of their many campaigns by adding your name, address and contact (email) information, and (may also add) a small donation to support their latest outcry over what is being claimed to ail the world.
