400 PPM Milestone Breached - Planetary Healing on the Way?
Despite the walls we build against change, one of the more frightening realities is our way of life may be sowing the seeds of our own destruction. This week saw an important milestone reached with the measurement of more than 400 parts per million carbon dioxide in the atmosphere from the Mauna Loa observatory in Hawaii. Scientists estimate that this is far beyond the safe threshold of 350 ppm and continue to warn that drastic changes in our life patterns are immediately necessary. Not many people still doubt that we need to wean ourselves off fossil fuels in order to avert some unpleasant planetary changes. But the earth may have some surprises in store for us. I read recently about how scientists can now measure the way trees pump out more aerosols in warmer weather to effectively act as a negative feedback in stimulating cloud cover. And a surge of sulfates and other minerals into the upper atmosphere from volcanic eruptions may also act to dampen the effects of climate change. So perhaps the planetary intelligence, of which we are a part, may be acting to heal itself. We can only hope, and continue to hold to the routines that heal us personally and collectively.
