Re "Where is water for new homes?" (Page A1, Feb. 23): Phillip Reese and Hudson Sangree wrote a very thorough article about California drought and the impact of water management on local growth.
However, they omitted one key contributor to drought: global warming. Higher temperatures cause more evaporation and drier soil. They also lead to winter precipitation falling more as rain and less as snow in the mountains. This causes the snow pack to shrink. Warmer temperatures also cause the snow to melt earlier in the year. As a result, we're losing this natural water storage system.
The California water supply is extremely important, especially with our state's agricultural productivity and associated water consumption. Thus, we need to mitigate the impact of global warming on drought by reducing greenhouse gas emissions. We need Californians to ask Republican members of Congress to protect our water supply by supporting a free market, small government, revenue neutral carbon tax.
