Are We Falling Off the Climate Precipice? Scientists Consider Extinction

Climate Change

British scientist John Nissen, chairman of the Arctic Methane Emergency Group (of which Wadhams is a member), suggests that if the summer sea ice loss passes “the point of no return,” and “catastrophic Arctic methane feedbacks” kick in, we’ll be in an “instant planetary emergency.”

Are We Falling Off the Climate Precipice? Scientists Consider Extinction

I grew up planning for my future, wondering which college I would attend, what to study, and later on, where to work, which articles to write, what my next book might be, how to pay a mortgage, and which mountaineering trip I might like to take next.

Now, I wonder about the future of our planet. During a recent visit with my eight-year-old niece and 10- and 12-year-old nephews, I stopped myself from asking them what they wanted to do when they grew up, or any of the future-oriented questions I used to ask myself. I did so because the reality of their generation may be that questions like where they will work could be replaced by: Where will they get their fresh water? What food will be available? And what parts of their country and the rest of the world will still be habitable?

The reason, of course, is climate change -- and just how bad it might be came home to me in the summer of 2010. I was climbing Mount Rainier in Washington State, taking the same route I had used in a 1994 ascent. Instead of experiencing the metal tips of the crampons attached to my boots crunching into the ice of a glacier, I was aware that, at high altitudes, they were still scraping against exposed volcanic rock. In the pre-dawn night, sparks shot from my steps.

The route had changed dramatically enough to stun me. I paused at one point to glance down the steep cliffs at a glacier bathed in soft moonlight 100 meters below. It took my breath away when I realized that I was looking at what was left of the enormous glacier I’d climbed in 1994, the one that -- right at this spot -- had left those crampons crunching on ice. I stopped in my tracks, breathing the rarefied air of such altitudes, my mind working hard to grasp the climate-change-induced drama that had unfolded since I was last at that spot.
