观测结果显示,美国、荷兰、西班牙和意大利的夜间亮度保持稳定。但是,该研究的第一作者、德国地学研究中心的克里斯多夫•凯巴称,考虑到观测不到的蓝光,基本上可以肯定这些国家的光污染有所增加。这项研究发表在《科学进展》上。
Also on the rise is the spread of light into the hinterlands and overall increased use. The findings shatter the long-held notion that more energy-efficient lighting would decrease usage on the global – or at least a national – scale.
与此同时,偏僻落后地区的夜间亮度也在上升,夜间照明使用量总体增加。这一研究发现粉碎了长期以来人们持有的一个观点,就是引进更节能的照明系统会减少全球——至少是全国范围内的——照明使用量。
“Honestly, I had thought and assumed and hoped that with LEDs we were turning the corner. There’s also a lot more awareness of light pollution,” Kyba told reporters by phone from Potsdam. “It is quite disappointing.”
“说实话,我原来的设想和希望是,有了LED照明系统,事情会有所转机。人们对光污染的意识会大大增强,”凯巴通过电话告诉德国波茨坦的记者说,“结果挺让人失望的。”
The biological impact from surging artificial light is also significant, according to the researchers.
研究人员表示,人工照明激增也给生物造成了重大影响。
