[轉文]The Yellow River no longer flows to the sea

Climate change will also alter the patterns of precipitation and evaporation in ways that are still poorly understood. Dry place are likely to get direr; rainfall is likely to arrive in fewer but more concentrated episode; and extreme weather events such as tropical cyclones are likely to increase in intensity. My colleagues at the Earth Institute at Columbia University, for example, have used both theoretical reasoning and 1,00 years of tree-ring data to argue that global warming will likely intensify droughts in the American West. Some evidence, still heavily debated, suggests that warming surface temperatures in the Indian Ocean may be leading to droughts in parts of East Africa.
Solutions will not be simple. Yes, better pricing of water will lead to much greater efficiency. Drip irrigation can reduce the water demand of crops. Desalination can vastly expand water supplies, through of crops. Water storage systems can spare farmers the misery of crop failures. But these solutions presuppose vast expenditures of capital, and such solutions do not automatically address the needs of the poor, who are unable to pay for that capital. Moreover, such solutions are often not commensurate with the scale of the challenge because they can bring huge adverse ecological consequences.
Securing water for a growing world will require the best of science, ecology, economics, ethics and international cooperation. With regard to climate change, the intergovernmental Panel on Climate Change has done remarkable work in mobilizing the search for scientific consensus and possible solutions. A parallel effort on the science, technology and policy for water could prove to be of similar global benefit.

[心情]The first PotLuck at UCSB

Today. it is my first time to have potluck at UCSB. All Taiwanese are getting together and sharing their experience that at UCSB. It is terrific meeting for new student. Now, I am studying for Quantum Physics. I will write more for this!

[轉文]Because I love you

Because I love you -Shaking Steven

If I got down on my knees and I pleaded with you
If I cross a million oceans just to be with you
Would you ever let me down

If I climbed the highest mountain just to hold you tight
If I said that I would love you every single night
Would you ever let me down

Well, I'm sorry if it sounds kind of sad
It's just that I'm worry, so worry that you'll let me down

Because I love you
I love you, love you
So don't let me down

If I swam the longest river just to call your name
If I said the way I feel for you would never change
Would you ever fool around
