How climate change will hit home - Sacramento Opinion - Sacramento Editorial | Sacramento Bee
My 6-year old daughter Chiara is a member of what I call Generation Hot. That's the 2 billion people worldwide who were born after June 23, 1988, the day NASA scientist James Hansen's testimony to the U.S. Senate put the world on notice that man-made global warming had begun and threatened to make Earth uninhabitable.
Since then, humanity's greenhouse gas emissions have only accelerated. Now, the young people of Generation Hot are fated to spend the rest of their lives coping with the hottest, most volatile climate our civilization has ever known.
...
Scientists project that global warming will cause both deeper droughts and fiercer floods – a fiendish paradox. Meanwhile, the laws of physics and chemistry assure that global temperatures will rise for decades to come even if emissions are reduced. The rising temperatures will, among other things, also melt snowpacks.
In California, snowmelt is the source of nearly one-third of the freshwater supply. The Sierra Nevada snowpack will shrink by 25 to 40 percent by 2050, according to the California Department of Water Resources.
