在纽约举办的气候周期间，人工智能与气候变化的关系成为讨论的中心议题。联合国秘书长古特雷斯表示，"人工智能既可能帮助解决所有这些挑战，也可能让问题更糟"1。联合国气候负责人西蒙·斯蒂尔指出，"AI领导者在获得经营许可证方面岌岌可危，在获得公众支持方面更是深陷困境"1。
AI与气候行动之间存在复杂的双重关系。一方面，全球气候科技风险投资在2026年上半年达到260亿美元，同比增长55%1，显示出AI推动了可再生能源投资增长。另一方面，数据中心的能源需求却对科技公司造成了沉重负担。微软、谷歌和Meta均未能实现碳排放目标，主要原因在于数据中心的能源消耗激增1。MIT能源气候副总裁埃夫琳·王估计，数据中心还需约十年时间才能不再增加全球变暖排放1。碳管理和低碳燃料领域的风险投资今年出现大幅下滑1。
Artificial intelligence has emerged as a dominant topic during Climate Week in New York, with major focus on its dual potential to either mitigate or worsen the global climate crisis.1 UN Secretary-General António Guterres emphasized this tension, stating that "Artificial intelligence could help solve all these challenges, or it could make them worse."1
The technology sector's environmental footprint has become a key concern at the gathering. Major tech companies including Microsoft, Google, and Meta have failed to meet their carbon emission reduction targets, primarily due to surging energy demands from data centers.1 UN climate chief Simon Stiell warned that "AI leaders are now on thin ice when it comes to license to operate and sinking deep underwater when it comes to public support."1 According to Evelyn Wang, MIT's vice president for energy and climate, data centers will require approximately a decade before they stop adding to global warming emissions.1
Despite these challenges, climate technology investment has shown mixed results. Global climate tech venture capital reached $26 billion in the first half of 2026, representing a 55 percent year-over-year increase, driven largely by renewable energy investments.1 However, this growth contrasts sharply with carbon management and low-carbon fuel investments, which have experienced significant declines this year.1 The world approaches a critical threshold where global warming can no longer be contained within 1.5 degrees Celsius above pre-industrial levels.1
