The Keeling Curve Crosses a Milestone

For the first time in over 3 million years, the carbon dioxide levels have crossed the 400 parts per million (ppm) milestone.

According to National Geographic News, “the last time the concentration of Earth’s main greenhouse gas reached this mark, horses and camels lived in the high Arctic. Seas were at least 30 feet higher—at a level that today would inundate major cities around the world.

Historically, an increase of 10 parts per million may have occurred over the course of 1,000 years or more, but humans have accelerated the speed at which carbon dioxide concentrations are increasing.  At this rate, the planet is poised to reach the 1,000 ppm level in less than 100 years.

Question to you is, “are you ready for the impending climate crisis?”
