John Piotti of American Farmland Trust has dedicated his career to preserving rural farms and the local economies they support in the Northeast, and now he’s taking his message to the rest of the United States.
Temperature increases during dry periods outpace average climate warming, say researchers at the University of California, Irvine. They point to concurrent changes in atmospheric water vapor as a driver of the surge.
Scientists from Lawrence Livermore National Laboratory and other organizations have shown that human influences significantly impact the size of the seasonal cycle of temperature in the lowest layer of the atmosphere.
Agriculture on the Great Plains in the coming decades may be adversely affected by a shifting of the climate boundary due to global warming, says Richard Seager, a climate scientist at Columbia University.
Scientists have already warned that climate change likely will impact the food we grow.
But new research is showing that climate change is expected to accelerate rates of crop loss due to the activity of insects.
A new study led by researchers at Indiana University has found that modifications such as dams and reservoirs in the U.S. and Canada do not isolate rivers and streams from the effects of climate change.
