US agriculture is already feeling the effects of climate change.
A four-member panel of scientists organized by the American Association for the Advancement of Science (AAAS), with the support of US Senator Tom Harkin of Iowa, has warned of an impending agriculture calamity as crops are impacted by climate change.

Senior research scientist Dr. Cynthia Rosenzweig of the US National Aeronautics and Space Administration (NASA) explained that the nation’s Northwest and Southeast regions are already seeing significantly reduced rainfall, while other areas are seeing higher-than-average rainfall, both of which adversely affect crop yields.

Meanwhile, abnormal temperatures are also hampering the proper development of crops. The panel further warned that unstable agriculture could double grain prices by 2050, which could set off civil unrest.
These experts called for mitigation strategies to curb anticipated crop failures and low yields across the globe.

Alarming as they are, your warnings are appreciated, Dr. Rosenzweig and colleagues. Let us quickly make the greenest, most sustainable switch to the organic vegan lifestyle to ensure global food and overall security.

Supreme Master Ching Hai has frequently emphasized such critical dangers associated with global warming, as during an August 2009 videoconference in Thailand, where she also highlighted the fastest solution.

Supreme Master Ching Hai: The leaders of the nations must do something. The people of all nations must do something. Just because we can still sit here pretty and talk, just because in our area there is not yet water shortage or food prices going up, doesn’t mean it will not happen to us soon.

We have to do something to avoid the tragedy that is already happening to billions of other people. There are one billion people hungry already because of climate change, and short of water and food.

Please take action now. Very simple. Just be veg. Just be veg is truly enough for now. And it will be enough for a long future to come.

US scientists report that while nearly all of the oil from the recent leak has disappeared from the Gulf of Mexico due to the presence of oil-consuming microbes, the seawater’s oxygen content is now very low, with more research needed to determine other possible long-term effects.

The European Environment Agency finds that average temperatures in the legendary Alps have increased by two degrees Celsius in the past century, which is twice the average rate of the Northern hemisphere and has caused a correspondingly significant loss in glacier volumes.
