Climate Case Study: California Drought (1)
By: Dr. Ricky Rood
Published: August 22, 2014
I can’t help but think of the carnivores finding the easy pickings of the herds collected around the drying water holes at what would become the Agate Fossil Beds. Then, from that, we don’t have to be beardogs. We humans are unique because of our ability to remember, to reason, to develop and to accumulate knowledge; we have the ability to make decisions that influence the future of our environment.

An extreme deluge nearly unprecedented in Baltimore history swamped the city in flood waters that closed multiple expressways on Tuesday afternoon. Officially, 6.30" of rain fell at the Baltimore Airport on Tuesday. This was their second wettest calendar day in history.
Wunderground's Climate Change Position
Based on the evidence, more than 97% of climate scientists have concluded that human-caused climate change is happening. Climate change is already causing significant impacts to people and ecosystems, and these impacts will grow much more severe in the coming years. We can choose to take economically sensible steps to lessen the damage of climate change, and the cost of inaction is much higher than the cost of action.
