This video from Pentatonix was their big breakout back in 2013 right after Thanksgiving. They're up there by Mt. Wilson in a forested notch sitting conspicuously on the mountain slopes above Altadena (Pasadena) in the San Gabriel mountains, USA. It's above the Eaton Canyon falls that run fast in the spring from the creek beside the trail. Watch the background in the video, you'll see the skyline of downtown LA, and beyond that, the Pacific ocean. They recorded this on a day with that gorgeous light playing through the clouds on a crisp winter afternoon in a dramatic sky.
It was shot before the drought took hold and seized our hills with its dusty grip of heated breath. Dried, brown vegetation covers the hills now even in December; the trees and shrubs are straggling across the hillocks. We don't see these clouds very often now, it's endless blue hazy sky, sometimes with remnants of smoke from the fires that have scorched the Southern California region for months. Blazing red sunsets from haze and pollution appear all summer and through the winter...
It's been our season of fires, of unrelenting winds from the deserts, and some researchers project that fires driven by Santa Ana winds, and the fires that occur earlier in the year in Southern California, will burn larger areas by midcentury in part due to rising temperatures. Our part in this horrific destruction is the encroaching urban hardscape and structures into areas that can't sustain it, that pave over and smother the very landscape that provides the necessary cycles of water and aquifer retention that we rely on. This, in addition to the warming planet, sets the scene for even worse destruction as well as massive deforestation from the die off of the forests in our mountain ranges. Climate change is now preventing the fall rains from tempering the natural fire cycle.
Climate scientists are sounding the alarm, the global climate changes predicted decades ago are accelerating far more rapidly than even they predicted. We may be facing a dramatic shift in to an uncontrollable climate change feedback from the increasing sensitivity of the planet due to this heat gain from carbon. Unless we can act rapidly, the verdant hills of our home will be gone very soon.
