科学家告诫说,应对气候变化的极地地球工程可能损害生态系统,而且代价太高。 Scientists caution that polar geoengineering to fight climate change could harm ecosystems and is too costly.

气候科学家警告说,拟议应对气候变化的极地地球工程可能由于严重的环境风险和高昂的成本而不可行。 Climate scientists warn that polar geoengineering, proposed to combat climate change, may not be viable due to severe environmental risks and high costs. 联合王国为实地试验提供了资金,但最近的研究表明,抽取海水或分散颗粒以冷却地球等方法可能会损害生态系统并导致可行性测试失败。 The UK has funded field trials, but recent studies show that methods like pumping seawater or dispersing particles to cool the Earth could harm ecosystems and fail feasibility tests. 研究人员强调注重减少排放,代之以利用可再生能源。 Researchers emphasize focusing on reducing emissions and using renewable energy instead.
