Understandable Earth Science

Nice summary highlighting some of the problems with ignorance in climate science.

Critical Angle

Geologists, especially those, like me, of a certain age, often have problems with climate science and the idea that humans may be triggering a massive and abrupt change in the climate. Global change, we were taught, occurred slowly and by commonplace mechanisms: sediment carried by water, deposited a grain at a time: erosion effected by water and wind, the hardest rocks slowly ground down crystal by crystal. The great features of the Earth—the canyons, mountains and basins—were built this way and owe their grandeur to Deep Time, geology’s greatest intellectual gift to human culture. In the face of the history of the natural world, geologists feel a certain humility at the insignificance of humans and our tiny lifespans.
