Jim Samples Quotes & Sayings

Data from ice core samples taken from glaciers and ice caps have allowed scientists to provide fairly precise global average temperature estimates going back several hundred thousand years. These data show that the stability of Earth's climate over the past 10,000 years is highly atypical. Most of human and hominid history over the past two million years is punctuated by sharp swings in climate and by more than twenty ice ages. In mere decades, average temperature sometimes changed by half the difference between today's conditions and an ice age, with some continental shelf coastlines invading by miles.32 — Jim Rubens
