WASHINGTON: A new United Nations scientific report examines how global warming and land interact in a vicious cycle. Human-caused climate change is dramatically degrading the land, while the way people use the land is making global warming worse.
“The cycle is accelerating,” said NASA climate scientist Cynthia Rosenzweig, a report co-author. “The threat of climate change affecting people’s food on their dinner table is increasing.”
Earth’s land masses, which are only 30% of the globe, are warming twice as fast as the planet as a whole. While heat-trapping gases are causing problems in the atmosphere, the land has been less talked about as part of climate change. A special report, written by more than 100 scientists and unanimously approved by diplomats from nations around the world at a meeting in Geneva, proposed possible fixes and made more dire warnings.
