Turns out, humans have been leaving their mark on the climate for way longer than we thought—like, since the 1890s! Scientists dug into old atmospheric data and found clear signs that people were the main drivers of climate change even before cars were a thing. If only scientists back then had our tech, maybe we could’ve dodged some of this mess. Wild to think our fingerprints have been all over this crisis for 130 years! #Science #ClimateChange #ScienceNews
