CO2 in the atmosphere just exceeded 415ppm for the first time in human history
What I don't understand is why this is so controversial. I clicked on a link in the article, leading to this article: https://techcrunch.com/2019/05/06/new-study-shows-human-deve.... The comment on it is extremely dismissive about climate change. I see this on pretty much every news website nowadays. First of all I don't see how man-made climate change is even controversial with the amount of evidence we have, but furthermore I don't see why we shouldn't transition to renewable energy asap anyway. Even if climate change would be a hoax (which it is not), then why would it be a bad thing to make changes to prevent it from happening anyway? Why would it be a bad thing to get rid of air pollution? Why would it be a bad thing to switch to an energy source that doesn't run out in ~20 years simply because it isn't renewable?
