Image of the Day: Moss May Explain Earth’s Mini Ice Ages

By 460 million years ago, CO2 levels were cut in half and the planet experienced a series of “mini ice ages”. Until now, it was thought that the arrival of larger plants and trees consuming the CO2 was the explanation, but a new study published in Nature Geoscience offers a new theory: moss. According to researchers, the invasion of land by primitive moss-like plants with voracious appetites for CO2 was a pivotal time in our history and could, indeed, explain the huge changes to our planet.                                                                                                                                                          Credit: Geoff Grant
