When Is the Next Ice Age Really Coming?

Every single time climate change comes up in conversation, like clockwork, someone inevitably brings up Milankovitch cycles. "The climate has always changed," they say. "It's just Earth's natural astronomical cycles." And with a smug air, as if they'd just discovered fire, they sweep away decades of scientific research with a wave of their hand. The problem? They're mixing apples and oranges - or rather, they're confusing processes that operate on completely different timescales. And this isn't an innocent mistake: it's a distortion that needs to be dismantled piece by piece, with hard numbers. Let's start with the facts. Milankovitch cycles are real - they exist, and no serious scientist denies them. Named after Serbian mathematician Milutin Milankovitch, who in the 1920s calculated how three orbital parameters of Earth influence the amount and distribution of solar energy reaching our planet. The first is the eccentricity of Earth's orbit - how much our path around the Sun deviates from a perfect circle. This parameter oscillates with a main period of about 100,000 years. The second is obliquity, the tilt of Earth's axis relative to the orbital plane, which varies between 22.1 and 24.5 degrees with a cycle of about 41,000 years. The third is the precession of the equinoxes, a wobbling motion of Earth's axis that completes a full rotation in about 26,000 years. -- DISCUSSIONS & SOCIAL MEDIA Commercial Purposes: insanecuriositybusiness@gmail.com Tik Tok: https://www.tiktok.com/@insanecuriosity Reddit: https://www.reddit.com/user/insanecuriosity Instagram: https://instagram.com/insanecuriositythereal Twitter: https://twitter.com/insanecurio Facebook: https://facebook.com/InsaneCuriosity Linkedin: https://www.linkedin.com/in/insane-curiosity-46b928277/ Our Website: https://insanecuriosity.com/ -- Credits: Ron Miller, Mark A.
