Climate Control
A couple of days ago I took a walk in our neighborhood, and it was clear that spring has sprung, at least in Atlanta. It was stunningly beautiful, as spring always is in this part of the world. I forget sometimes how colorful spring is. Many shades of green, of course, and around us flowers that seem to lean to shades of blue and yellow. But there is also a wide range of colors in the buds of the trees - especially in coppers, burnt orange, and red tones. Two trees stood out on my walk. I came around a bend and there was a glorious maple right in front of me. A kind of yellow green color that took your breath away with the light that was on it. Maples are one of my favorite trees, and this one was wonderful. We have three flowering cherry trees in one corner of our lot, and coming down the block I could see them from four houses away. They are in full bloom now, white with just a hint of pink. Lovely.
It is early for spring to be this far along. And hot. Today we set a record high for the date. (It's also dry - we ae at present over 6 inches behind our normal rainfall.) And I am worried. When we lived in Dahlonega a few years back, I managed a camp that I had attended as a boy in the 1960s. In those long-ago days, you always needed a light jacket and a blanket for the cool nights that were a part even of mid-summer. By the late 1980s that was no longer true. It never got that cool. Old timers talked about how it didn't snow like it used too. It's hotter, and I am worried.
In the February 20th edition of the Christian Century, Bill Mc Kibben has an article called "Meltdown". It raaises the alarm for us about global warming. Part of one paragraph reads like this:
the temperature rise has been enough to start melting every frozen thing on earth, which
in turn creates it's own problems. In the Arctic Ocean, nice white ice that reflected
lots of the sun's rays back to space isquickly turning into nice blue water that absorbs
much more of the sun's heat, amplifying the warming. ... Scariest of all, the great ice
sheets above Greenland and the West Antarctic appear to be melting faster thasn predicted.
There's the real chance of a catastrophic rise in sea level, one that would endanger the
world's coastal cities, inundate much prime farmland, and drive hundreds of millions
from there homes.
The article suggest that we may have at best 10 years to stop the impendind crisis.
I know there are natural cycles of heating and cooling on the earth. And we may be in a natural heating swing. But even if that is true, the evidence seems overwhelming to me that our actions - my actions - are making things worse. My greatest fear is for my children and my grandchildren. What will they have to deal with? And why is it so hard for me to take the hard actions that are needed in the face of this mess? God help us all. And help us to change our ways.
