“As I get a little bit older and wiser, I realize that I’m less and less of a machine.”

In case you couldn’t guess, those words came from “The Governator,” or the former California Gov. Arnold Schwarzenegger, who hosted a public comment forum that I attended last week at the University of Southern California (USC) for the recently drafted National Climate Assessment Report. The report focuses on climate change’s projected impacts on the U.S., and this forum brought attention to the Southwest (our country's hottest and driest region).

As I sat amongst a suit-wearing, predominantly male audience, the atmosphere felt somewhat stiff. But the Governator’s quip seemed to put us at ease before we began to absorb the findings on this serious, life-threatening matter.

The chairman of the USC Schwarzenegger Institute (in partnership with the USC Center for Sustainable Cities) likened the report to a doctor’s yearly physical—only the doctors, in this case, are climate researchers.

“The National Climate Assessment is our physical,” he said, underscoring the need to listen to expert diagnoses before the country has its own “heart attack.”

The “doctors” at the April 8 forum covered many critical issues. The quantity of information was overwhelming at times, but here were a few predictions that stood out. For example, if we continue at the current emissions rate:

  • “Megafires,” which burned between 40,000 and 60,000 acres in Arizona and New Mexico in 2011, will likely occur more frequently and rampantly.
  • The bark beetle epidemic, for which drought and high temperatures create favorable conditions, will kill off more trees (“forest thinning”) of all breeds and elevations.
  • Aggravated urban irrigation water shortages, which could shift Southwest crop demands northward, will likely “displace growers and impact communities.”1
  • Average temperatures will climb in the Southwest as much as 9.5 degrees Fahrenheit by 2100 (based on 1971 and 1999 data).2

Furthermore, I’m guessing prospects for the land of golden opportunities (or, as The Governator calls it, “Cah-lee-for-nee-uh”) were particularly interesting to the room, not only because it’s our home, but also because of our state's gargantuan economy. Here are two examples of what could happen to California:

  • Winter flooding, erosion, and sea level rise will impact the coast. “All these tech giants are vulnerable,” a Bay Area-based co-author remarked, referring to Silicon Valley organizations, like Apple and Google, whose communication products many rely on every day.
  • High surface temperatures will likely increase mortality rates, particularly for children up to 5 years old and for people of color in impoverished communities.

These are just some examples of the probable forthcoming damage. By the end of the talk, a part of me wanted to bury my head in sand to cease listening to these grueling findings. But on the flip side, I knew that wouldn’t do me—or anyone on this majestic planet—any good.

I listened to the commentators from political, private, scientific, and academic (students and professors) backgrounds, and their views often aligned with what The Governator implied: If we don’t take care of ourselves and our planet by following expert advice, we could end up in an irreversible situation. It’s simple wisdom, and I got the vibe that many were willing to move forward to help avoid those worst-case scenarios.
