When did we start pushing the 350 thing?



  1. 0 Votes

    350, which represents 350 parts per million (ppm), is a movement to curb carbon greenhouse gas emissions. 350 ppm is the proposed limit to these emissions for humanity to survive which is a problem since the current level is around 387 ppm. The “350 thing” only began within the last 5 years, which is when mass knowledge began to accrue. Of course, realizations of climate change began as far back as 30 years ago as scientists were able to study climate change evidence.
