其中一个创新方法不是仅仅去避免,而是真正恢复北极迅速融化的冰川、冰原和海冰,目前北极变暖速度是地球上其他地方的二倍。
The solution, according to scientists at the aptly named non-profit Ice911 (“Take action for a cooler planet”), is to liberally scatter silica beads as fine as sand onto the ice to prevent it from melting by reflecting back the Sun’s rays.
名为Ice911的非营利组织(“努力给地球降温”)的科学家说,这一方法就是把细如沙子的硅珠大量撒在冰上,通过反射太阳光防止冰融化。
Reflective ice and snow are key to preventing the Earth from overheating. White surfaces like these reflect most of the radiation from the Sun’s rays back into space, keeping the planet cool and preventing further melt.
反光的冰雪是防止地球过热的关键,这些白色表明将大量太阳光中的辐射反射回太空中,保持地球凉爽,避免冰川进一步融化。
Reduced ice and snow that reveal darker surfaces like the ground, sea, or meltwater absorb more of this energy, trapping it as heat so the global temperatures rise and more ice melts. It’s a vicious cycle.
冰雪减少,露出地面、海洋或冰雪融水等深色表面,会吸收更多能量,将其转化为热量,导致全球气温上升,更多的冰融化,如此恶性循环。
