Washington: On the ground, climate change is hitting us where it counts: the stomach — not to mention the forests, plants and animals.
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.
Thursday’s science-laden report says the combination is already making food more expensive, scar-cer and even less nutritious.
“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.”
But if people change the way they eat, grow food and manage forests, it could help save the planet from a far warmer future, scientists said. Earth’s land masses, which are only 30 per cent 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.
“The way we use land is both part of the problem and also part of the solution,” said Valerie Masson Delmotte, a French climate scientist who co-chairs one of the panel’s working groups. “Sustainable land management can help secure a future that is comfortable.”
Scientists in Thursday’s press conference emphasized both the seriousness of the problem and the need to make societal changes soon.
