根据第一段中的“We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度)and nutrient availability seem to have trumped the benefits of increased carbon dioxide”可知科学家原来以为二氧化碳的增加会导致物种变大,但是气候...
The world risks losing these opportunities, however, if we continue with a business-as-usual approach. Increased emissions entering the atmosphere coupled with continued environmental degradation will lessen the impact that nature can have. If natural climate solutions are mobilized over the next 10 t...
