With melting glaciers and rising seas as his backdrop, President Barack Obama will visit Alaska next week to press for urgent global action to combat climate change, even as he carefully calibrates his message in a state heavily dependent on oil.
About half the energy burned in the U.S. is used to make hot water and heat (most of which is below the boiling point), yet PV solar and wind energy do little to provide it aside from electric water tanks and inefficient baseboard heaters.
The most extraordinary fact about public awareness of evolution is not that 50 percent don’t believe it but that nearly 100 percent haven’t connected it to anything of importance in their lives. The reason we believe so firmly in the physical sciences is not because they are better documented than evolution but because they are so essential to our everyday lives. We can’t build bridges, drive cars, or fly airplanes without them. In my opinion, evolutionary theory will prove just as essential to our welfare and we will wonder in retrospect how we lived in ignorance for so long.
