Turns out, a ton of the carbon dioxide that spiked after the last Ice Age wasn’t just from the oceans—it was from thawing permafrost up north! Scientists found that as ancient ice melted, all that frozen grass and soil released massive amounts of CO2, helping to warm the planet. Now, with today’s permafrost melting even faster thanks to us, we could be unleashing another carbon bomb. Wild, right? #Science #ClimateChange #Permafrost
