Jeff Masters, who used to write a neat blog for Weather Underground before weather.com/IBM destroyed everything that was ever good about that site, has a dark take on climate change. He now writes on Yale Climate Connections, which is okay, but I notice that one by one my beloved RSS feeds are falling prey to neglect (there’s an RSS feed for Yale Climate Connections, which is okay, but not one for Jeff Masters’s blog specifically.)

When the ice sheets of Greenland and Antarctica melt, the forests of the Amazon transition to scrubland, and vast swaths of once-fertile land become inhospitable desert, there will be no climate change vaccine that will suddenly bring an end to these essentially irreversible catastrophes. Tens of millions will starve. Wars will break out over scarce resources. Hundreds of millions of climate change refugees will flee rising seas, coasts will be ravaged by stronger storms, and desert-like lands will be without the food and water needed to sustain civilization.

I think that’s a pretty good elevator pitch for the “why should I care?” crowd: (1) massive melting of ice sheets on both poles leading to catastrophic sea level rise, (2) loss of the Amazon rain forest, which along with the oceans maintains the mix of gases in the atmosphere that we have become accustomed to throughout human history, (3) loss of huge amounts of what used to be productive farm land, due to high temperatures and lack of water. These processes will play out slowly, maybe over decades. We are the frogs in the slowly heating up cook pot. We may see slowly rising prices for food, and we will have to clean up after increasingly frequent storms, floods, and fires. Eventually we may see absolute food shortages. These acute crises will start to affect poorer nations, and poorer people in richer nations, before others, of course. Mass migrations, civil conflicts within nation-states, and geopolitical conflicts between nation-states may break out. Throw in a few random events like earthquakes and pandemics at already vulnerable moments, and things may get dicey.

This sounds awful, and there is certainly no worldwide effort to effectively deal with it. At the same time, science, technological know-how, and financial wealth continue to increase, although they obviously are not spread equally or fairly among the world’s people. We have seen examples of effective leadership and cooperation in the past at times of crisis, and maybe these will emerge again. As Jeff Masters rightly points out though, unlike wars and pandemics, a big difference with climate change is that when it becomes obvious to absolutely everyone that something has to be done, there may be no good options left.
