HMM: Algal Blooms Could Have Caused Last Ice Age. “At various points in Earth’s history, dust fell into the ocean and fed algae, which gobbled up carbon dioxide and sank to the bottom of the sea, taking greenhouse gas with them and cooling the world. That’s a key conclusion scientists are drawing from an unusual 2004 experiment in which they grew a massive algae bloom in the Southern Ocean. Data from the experiment may also tell researchers whether seeding the seas with iron is a good way to curb global warming.”

What if, a la Fallen Angels, the Earth is already in an Ice Age but human CO2 emissions are masking that fact — until we stop them in an effort to combat global warming?

Nah, that’s silly.
