So, the only way you can think this is if you've only engaged with the subject of climate change via social media and those around you. This is not a criticism. It's perfectly okay not to have dug deeper.
I highly recommend actually taking a look through the evidence of climate change (all peer reviewed, and independently scrutinised. The
IPCC is a group of 1300 scientists and experts who have carried out the analyses.). This will show you that the average global temperature is rising at a frightening rate, and directly correlates with mankind's activities in the past 100 or so years. NASA, The WWF, The Royal Society, and multiple other websites are all there to be looked over. Easy Google search.
It's scary, but very worthwhile getting the facts, instead of the stuff people peddle on social media to earn a living off outrage and bias.
