气候报告称，食物将会变得稀缺、昂贵和缺乏营养

Food will become scarcer, grocery prices will spike and crops will lose their nutritional value due to the climate crisis, according to a major report on land use from the United Nation's Intergovernmental Panel on Climate Change released Thursday.

根据联合国政府间气候变化专门委员会周四发布的一份关于土地利用的主要报告，由于气候危机，粮食将变得更加稀缺，杂货价格将会飙升，农作物将失去营养价值。

The climate crisis will also change what kinds of crops farmers can grow. Some climates will become too hot for what farmers are growing now. Some climates will see more flooding, more snow, more moisture in the air, which will also limit what can be grown.

气候危机也将改变农民可以种植的作物种类。有些气候将变得太热，不适合农民现在种植的作物。一些气候将会预见更多的洪水，更多的雪，空气中更多的水分，这也会限制可以生长的东西。

"The window is closing rapidly to have lower emissions and to keep warming to less than 2 degrees.That is the key message of this report," said one of the report's authors, Pamela McElwee, an associate professor of human ecology in the School of Environmental and Biological Sciences at Rutgers University.

罗格斯大学环境与生物科学学院人类生态学副教授帕梅拉·麦克尔韦 表示：“窗口正在迅速关闭，以降低排放，并将气温保持在2摄氏度以下。这是这份报告的关键信息。”该报告的作者之一帕梅拉·麦克尔韦是罗格斯大学环境与生物科学学院的人类生态学副教授。

The report found that food nutrition could also decline. Wheat grown at high carbon dioxide levels, for example, will offer 6-13% less protein, 4-7% less zinc and 5-8% less iron, according to experiments done with these plants.

报告发现，食物营养也可能下降。例如，根据对这些植物的实验，在高二氧化碳水平下种植的小麦，蛋白质含量将减少6-13%，锌含量将减少4-7%，铁含量将减少5-8%。

"We are studying how this would translate into the food we eat and also in a range of different crops, we are seeing similar results," said one of the report's authors, Cynthia Rosenzweig, a senior research scientist at the NASA Goddard Institute for Space Studies, where she heads the Climate Impacts Group.

该报告的作者之一辛西娅·罗森茨韦格(Cynthia Rosenzweig)说，“我们正在研究这将如何转化为我们吃的食物，以及一系列不同的农作物，我们看到了类似的结果。”她是NASA戈达德太空研究所的高级研究科学家，负责气候影响小组。

Given that extreme events like the summer's heat wave in Europe are increasing in magnitude and intensity, food systems are already showing some strain, she said.

她说，鉴于像欧洲夏季热浪这样的极端事件在规模和强度上都在增加，食品系统已经显示出一些压力。

Undernourishment has long been a concern of scientists who watch the climate crisis closely.

营养不良一直是密切关注气候危机的科学家们关注的问题。

When you don't have enough to eat it reduces your ability to function physically. It can diminish your ability to think clearly. It puts you at a greater risk for chronic disease and death, studies show.

当你没有足够的食物时，它会降低你身体机能的能力。它会削弱你清晰思考的能力。研究表明，它会让你面临更大的慢性病和死亡风险。

While still too many people don't have enough to eat, the world had been making progress in this area. In the 1990s, 1.01 billion people were thought not to have enough to eat. By 2015 it was 80.5 million, or about 11% of the global population, according to the US Department of Agriculture.

虽然仍然有太多的人没有足够的食物，但世界在这方面已经取得了进展。在20世纪90年代，10.1亿人被认为没有足够的食物。根据美国农业部的数据，到2015年，这一数字为8050万，约占全球人口的11%。

The climate crisis could reverse this progress.

气候危机可能会逆转这一进展。

A study published in May that looked at the production of the top 10 global crops -- barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugarcane and wheat -- found that because of the climate crisis, the world has already seen a reduction of 35 trillion calories every year. That equates to about 1% of food calories lost each year.

今年5月发表的一项研究了全球前十大作物-大麦、木薯、玉米、油棕榈、油菜籽、水稻、高粱、大豆、甘蔗和小麦的产量-发现，由于气候危机，全世界每年已经减少了35万亿卡路里。这相当于每年损失的食物卡路里的1%。

"That means you are removing food calories for about 50 million people," said study author Deepak Ray, a senior scientist with the Institute on the Environment's Global Landscapes Initiative with the University of Minnesota. "Maybe in the future we will see even more lost, unless we prepare for it and draw down the carbon emissions."

“这意味着你正在为大约5000万人消除食物卡路里，”研究作者、明尼苏达大学环境研究所全球景观倡议的资深科学家迪帕克·雷说。“也许将来我们会看到更多的损失，除非我们做好准备，减少碳排放。”
