For the climate crisis, we have only ourselves to blame

COMMENTARY rapidly. Like, right now. Yet emissions last year reached an all-time high.

Despite what Trump and other ignoramuses might say, there is essentially no scientific disagreement about the fact that climate change is occurring or the fact that humankind is the cause.

A bulletin last week from the World Meteorological Organization, a U.N. agency, reported that the concentration of heat-trapping carbon dioxide in the atmosphere has risen by an incredible 47% since the Industrial Revolution. By examining the levels of various isotopes of carbon in the air, WMO scientists were able to show that the added carbon is of the kind emitted when coal and other fossil fuels are burned.

In other words, we’ve been found standing over the victim with the murder weapon in our hands.

At the Madrid climate summit — where House Speaker Nancy Pelosi is the highest-profile U.S. attendee — the assembled leaders will hear that prior assessments of climate change catastrophe were understated. Global warming is happening faster than predicted, with more dramatic consequences than previously imagined. Glaciers are melting. Seas are rising. Weather patterns have shifted in unpredictable ways, making monsoon rains unreliable, generating supercharged hurricanes and exposing once-temperate regions like Northern Europe to deadly heat waves.

The earth is immensely large, while each of us individually is very small. It may be difficult to imagine that we could have such a big impact on the environment. But look at photographs of the planet taken by astronauts and note how thin the atmosphere is. The air we breathe extends upward only roughly 10 miles — the distance many of us commute each day in our carbon-spewing SUVs and pickup trucks.

That issue of scale is one impediment to the kind of climate action we desperately need. An even bigger problem is the question of time.

We of the boomer cohort will long have returned to dust before climate change begins to feel like an everyday five-alarm crisis. Our children will feel it, though, and our grandchildren will suffer in ways we can only begin to grasp. Future generations will be mystified and furious. They will see from the historical record that we knew what was happening, that we knew of ways to at least slow it down — a carbon tax, for example — and that we did almost nothing.

Our benighted leaders fail to give us meaningful action on climate change because we fail to demand it. We can’t look to the Madrid conference to save the planet. We must look within.
