2012年11月,由世界银行公布的题为《降低热度:为什么要避免一个气温升高4℃的世界》研究报告引发热议。该报告指出,全球气温将在本世纪末增加4℃,各国目前的减排承诺不足以有效减缓全球变暖趋势。如果持续下去,其后果将是灾难性的。人类将可能面临沿海城市被淹没、食品短缺、干旱地区变得更干、湿润地区更湿,以及很多地区遭遇史无前例的热浪、水资源匮乏情况恶化、热带飓风强度加大、生物多样性遭遇不可逆转的损失等局面。“毋庸
In November 2012, a study released by the World Bank entitled ”Reducing Heat: Why Avoid A Climate That Rises 4 Celsius“ sparked heated debate. The report pointed out that the global temperature will increase by 4 ℃ by the end of this century and that the current national emission reduction commitments are not enough to effectively reduce the global warming trend. If it continues, the consequences will be catastrophic. Mankind will likely face submergence in coastal cities, food shortages, drier areas, wetter wetlands, unprecedented heatwaves in many areas, deteriorating water scarcity, intensifying tropical cyclones, and irreversible biodiversity Loss and other conditions. ”Needless to say
