美国国家航空航天局发布了一系列卫星照片,记录了阿萨巴斯卡油砂的扩张。阿萨巴斯卡矿区覆盖阿尔伯塔省超过 54,000 平方英里,估计储量为 1.75 万亿桶石油,足以使其在全球排名第三,仅次于沙特阿拉伯 (1) 和委内瑞拉 (2)。

从 20 世纪 80 年代中期至今,产量明显增加

照片中可见尾矿池,其中装有来自提取过程的受污染的水和物质,以及地表剥离。

那么,鉴于基斯顿 XL 输油管道几乎肯定会夭折,加拿大的油砂产量是否会在未来几年继续增长?或者,环境管理和碳意识是否会抵消全球对廉价能源的需求?

所有照片均由NASA/戈达德太空飞行中心提供。

更新:我们中的一些人一直在 Twitter 上讨论这些照片。 显然,美国宇航局的地球观测站网站拥有 1984 年至 2011 年之间每年的卫星图像,以及一个用于透视距离的比例尺。 查看它们以了解逐年进展。 谢谢,马修
