重点摘要
1. 气候变化将迫使数十亿人迁移
到2050年,更高的温度和更强的湿度将使全球大片地区对我们中的35亿人致命。
迫在眉睫的气候灾难。 世界面临环境、社会和人口灾难,预计到2100年气温将上升3-4°C。这将使热带的大部分地区因致命的高温、干旱、洪水和极端天气而无法居住。主要影响包括:
- 沿海城市和小岛国家被淹没
- 人口稠密地区的无法忍受的热浪
- 许多地区的农业崩溃
- 物种大规模灭绝和生态系统崩溃
被迫迁移。 气候变化将推动历史上最大规模的人类迁移:
- 到2050年,可能有10-30亿人被迫迁移
- 主要来源地区:南亚、非洲、中东、美洲部分地区
- 目的地地区:北部纬度、高海拔地区
这种动荡的规模和速度是前所未有的,需要紧急的全球规划和合作以人道地管理。
2. 迁移是自然且有益的人类行为
迁移不是问题,而是解决方案——它一直都是。
人类进化的成功。 迁移是人类生存和成功的关键。我们的祖先通过以下方式遍布全球:
- 通过文化和技术创新适应新环境
- 在群体中合作并形成社会网络
- 在不同人群之间交换资源、思想和基因
这种灵活性和适应性使人类在多样的栖息地中茁壮成长。
现代益处。 在现代世界中,迁移继续推动进步:
- 促进经济增长和创新
- 减少全球贫困和不平等
- 带来文化交流和多样性
- 帮助应对老龄化社会的人口挑战
迁移应被视为应对许多全球挑战的解决方案,包括气候变化适应。
3. 当前的移民政策不充分且有害
迁移被视为发达国家的安全风险,这是错误的,需要改变。
过时的范式。 当前的边境政策和反移民言论基于过时的固定国家身份观念。这种方法:
- 造成不必要的痛苦和死亡
- 浪费人类潜力
- 无法解决真正的人口和经济需求
需要新方法。 需要对移民政策进行彻底重新思考:
- 从安全转向经济框架
- 为气候移民创造合法途径
- 投资于整合和包容计划
- 解决被迫迁移的根本原因
如果管理得当,大规模迁移可以使发送和接收社会都受益。但这需要放弃当前的军事化边界和仇外政治范式。
4. 迁移推动经济增长并减少贫困
迁移是帮助国家实现几乎所有发展指标的最佳和最有效的方式,比大多数援助支出更有意义,即使在政治上通常不太受欢迎。
经济利益。 研究一致表明,迁移促进经济:
- 增加接收国的GDP增长
- 为关键行业提供劳动力并解决技能短缺问题
- 推动创新和创业
- 产生支持原籍国发展的汇款
减少贫困。 迁移是减少全球贫困的最有效方式之一:
-
移民在目的地国家的收入可增加3-6倍
-
汇款在许多发展中国家超过外援
-
技能和知识转移惠及原籍社区
-
例子:
- 2018年尼日利亚收到243亿美元的汇款(是其外援的8倍)
- 加拿大因移民而GDP增长25%
促进安全、合法的迁移途径是全球发展的强大工具。
5. 北方的新城市将成为气候移民的避风港
北纬45°以北将成为21世纪的繁荣避风港:它占地球面积的15%,但拥有29%的无冰土地,目前居住着世界上少数(老龄化)人口。
宜居性的转变。 随着热带地区变得危险地炎热,北部地区将变得更适宜居住:
- 加拿大、俄罗斯、斯堪的纳维亚将看到农业和经济利益
- 需要建设新城市以容纳数百万移民
- 现有的北部城市如安克雷奇、努克和丘吉尔可能繁荣
机遇与挑战。 这种向北的转变带来了机遇和挑战:
- 新的农业和资源开采用地
- 需要大规模的基础设施建设
- 对新开放领土的潜在冲突
- 永久冻土融化和生态系统变化的风险
规划和国际合作对于管理这一前所未有的人类地理转变至关重要。
6. 可持续食品生产必须适应气候变化
我们需要超越全新世的砍伐森林、创造裸地、撒种子并让阳光和雨水发挥作用的技术。
食品系统转型。 在更热的世界中养活90-100亿人需要重新构想农业:
- 转向植物性饮食和替代蛋白质(昆虫、实验室培育肉)
- 开发耐热和抗旱的作物品种
- 在城市中扩大室内和垂直农业
- 利用北部新开放的农业用地
海洋资源。 海洋提供了可持续食品的未开发潜力:
- 海藻和藻类养殖
- 可持续水产养殖
- 海洋永续农业系统
食品生产创新对于在更热、更少可耕地的星球上养活不断增长的人口至关重要。
7. 全球合作对于管理气候迁移至关重要
我们需要现在务实地规划,采用全物种的方法,确保我们的人类系统和社区具有应对即将到来的冲击的韧性。
新的全球机构。 管理大规模迁移需要新的国际合作形式:
- 具有实际权力的联合国机构来管理迁移流动
- 全球公民身份和护照
- 国家之间的负担分担机制
- 协调的城市规划和发展
重新思考主权。 传统的国家主权观念可能需要演变:
- 为移民设立特许城市和特别经济区
- 国家之间的土地租赁安排
- 区域治理结构(如北极理事会)
即将到来的动荡规模要求重新构想全球治理,以人为本。
8. 恢复自然和冷却地球是关键优先事项
为了将升温控制在1.5°C以下,我们必须在2025年前将全球排放量减半,并在2050年前实现净零排放。
自然恢复。 保护和恢复生态系统对于:
- 碳封存
- 保护生物多样性
- 维持关键生态系统服务
关键优先事项包括重新造林、湿地恢复和海洋保护。
气候干预。 为了避免灾难性变暖,我们可能需要考虑:
- 大规模从大气中去除二氧化碳
- 太阳辐射管理(如平流层气溶胶注入)
- 北极冰层保护技术
虽然有争议,但这些方法可能成为为减排争取时间和保护脆弱人群的必要手段。
9. 需要新的全球身份和治理系统
我们需要重新定向社会的生产能力,以应对气候变化和迫在眉睫的人口危机。
行星身份。 气候危机要求我们改变对自我的看法:
- 超越狭隘的民族主义,走向全球公民身份
- 认识到我们在地球健康中的共同利益
- 拥抱多样性和文化交流
人类世的治理。 需要新的机构和决策过程:
- 具有实际执行权力的全球机构
- 对行星规模决策的民主参与
- 长期规划视野(几十年到几百年)
我们面临的生存风险要求重新构想人类社会在行星尺度上的运作。
