The Urgency of NOW

After studying environmental issues for decades, I feel responsible to wake up as many people as possible to the fact that procrastinating on climate change is a horrific mistake.  If we wait to reduce our greenhouse-gas emissions drastically, we will make it virtually impossible to reverse, stop, or even slow global warming. Why? Because the current level of warming has already begun to trigger positive-feedback mechanisms, and, as the temperature goes up, those mechanisms will trigger more mechanisms, and then the warming will continue to accelerate to levels we don’t even want to think about.

As The Guardian explains:

Scientists are aware of a number of positive feedbacks loops in the climate system. One example is melting ice. Because ice is light-coloured and reflective, a large proportion of the sunlight that hits it is bounced back to space, which limits the amount of warming it causes. But as the world gets hotter, ice melts, revealing the darker-coloured land or water below. The result is that more of the sun’s energy is absorbed, leading to more warming, which in turn leads to more ice melting – and so on.

You can find another positive-feedback example, the release of methane as permafrost melts, in one of my earlier blogs. That post is entitled: IN WHICH I RANT IN CAPITAL LETTERS. Here’s a link to that post:

For lighter look at positive feedback, you might check out “The Sorcerer’s Apprentice,” from Fantasia. Here’s a link to it:

Below, you’ll find links to a couple of recent articles about where we now stand in regard to global warming.

What Would You Do?

Today, a headline in The New York Times caught my attention. It read:

Global Warming Cited as Wildfires Increase in Fragile Boreal Forest

Here’s a link to the article:

And here’s the first paragraph:

Scientists have been warning for decades that climate change is a threat to the immense tracts of forest that ring the Northern Hemisphere, with rising temperatures, drying trees and earlier melting of snow contributing to a growing number of wildfires.

The first paragraph of the article notes that scientists, for decades, have been warning that global warming would lead to fires like the one that recently devastated Ft. McMurray, Canada.

I know from personal experience that scientists have been predicting for decades a future of increasingly common wildfires in boreal forests. Fifteen to twenty years ago, some of my professors were among the scientists who made those predictions, along with a number of other predictions about the effects of global warming. Much of what they foresaw back then is coming true now.

So if I seem like an alarmist regarding the state of the environment, I hope you will put yourself in the place of someone who began studying scientists’ theories and empirical research decades ago and is now seeing researchers’ predictions come true. And while you’re at it, consider that I’ve also learned over the years that we’re in line for ever-worsening ecological and social disasters.

And now, I’d appreciate your advice. If you were me, how would you handle knowing that our best hope of avoiding ongoing ecological catastrophes is to reduce the stress that we’re putting on the planet? What would you do to motivate people to act?
