The southern California city is moving forward with an ambitious plan to run on 100% renewable energy and cut greenhouse gas emissions in half by 2035 and it’s doing so in a bipartisan manner.
Did climate change cause these ancient civilizations to collapse?
Drought is the great enemy of human civilization. Drought deprives us of the two things necessary to sustain life–food and water. When the rains stop and the soil dries up, cities die and civilizations collapse, as people abandon lands no longer able to supply them with the food and water they need to live. While the fall of a great empire is usually due to a complex set of causes, drought has often been identified as the primary culprit or a significant contributing factor in a surprising number of such collapses. Drought experts Justin Sheffield and Eric Wood of Princeton, in their 2011 book, Drought, identify more than ten civilizations, cultures and nations that probably collapsed, in part, because of drought. — Dr. Jeff Masters, writing in the Ten Civilizations or Nations That Collapsed From Drought
The Ancestral Puebloan (Anasazi) culture in the Southwest U.S. in the 11th – 12th centuries AD. Beginning in 1150 AD, North America experienced a 300-year drought called the Great Drought. This drought has often been cited as a primary cause of the collapse of the ancestral Puebloan (formally called Anasazi) civilization in the Southwest U.S., and abandonment of places like the Cliff Palace at Mesa Verde National Park in Colorado. The Mississippian culture, a mound-building Native American civilization that flourished in what is now the Midwestern, Eastern, and Southeastern United States, also collapsed at this time.

Silicor Materials Builds New Silicon Factory In Iceland
Silicor Materials is a 9-year-old California company that makes the silicon used to produce solar panels. Silicon requires a lot of power to manufacture, so the cost of energy is an important factor in producing silicon profitably. Iceland has an abundance of cheap electrical power, thanks to abundant hydroelectric and geothermal resources. That has led Silicor… Continue reading Silicor Materials builds new silicon factory in Iceland
