Researchers in Iceland found a new way of tackling climate change by pumping carbon dioxide underground and turning it into stone.
冰岛的研究人员发现了一种新的应对气候变化的方法，即通过向地下注入二氧化碳并将其转化为石头。
Other carbon capture and storage methods store carbon dioxide as a gas, but problems include a high cost and concern about leaks.
其他碳捕获和储存方法将二氧化碳作为气体储存，但问题包括高昂的成本和对泄漏的担忧。
This new method of bearing carbon dioxide and turning it into stone is cheaper and more secure. The Guardian reports.
这种将二氧化碳转化为石头的新方法更便宜且更安全。《卫报》报道。
To turn carbon dioxide into stone, researchers with the Carb Fix project pumped the gas into volcanic rock and sped up the natural process in which the volcanic rock reacts with gas and forms carbon minerals.
为了将二氧化碳转化为石头，参与“Carb Fix”项目的研究人员将气体注入火山岩中，并加速了火山岩与气体反应形成碳矿物的自然过程。
The gas turned into solid in just two years, much faster than the hundreds or thousands of years researchers had predicted.
这种气体在短短两年内就转化为了固体，远快于研究人员此前预测的几百年甚至几千年。
The research took place at Iceland's Helishidi power plant. Already, the project in Iceland has been increased in scale to bury 10,000 tons of carbon dioxide each year.
这项研究在冰岛的Helishidi发电厂进行。目前，冰岛的这个项目已经扩大了规模，每年可以掩埋1万吨二氧化碳。
One potential difficulty is that for each ton of carbon dioxide buried, the technique requires 25 tons of water.
一个潜在的困难是，每掩埋一吨二氧化碳，这项技术就需要25吨水。
However, the lead researcher said seawater could be used.
但主要研究人员表示，可以使用海水。
