July 2012 was the hottest month ever recorded, and 2012 is becoming the hottest year since record-keeping began in the nineteenth century. Global climate change is here now; it is not only a harmful problem for future generations. And it is bound to grow worse if we continue to ignore it, to deny it, or to devise ineffective mitigation measures that cannot possibly overcome it.
We must adopt a "de-carbonization" strategy that can replace the main sources of greenhouse gases, including fossil fuel producers, energy generators, and transportation industries, with "clean" GHG-free alternative technologies.
Here are nine clean replacement technologies that could help.

KSTAR aims for longer plasmas
At the Korea Institute of Fusion Energy (KFE), the KSTAR tokamak recommenced operations in December after a major upgrade to replace the device's carbon divertor with a tungsten divertor.
According to an article on the KFE website, the original carbon divertors could take a thermal load of 5MW/m², whereas the tungsten divertor can take 10MW/m². The upgrade is critical to the goal of sustaining a 100-million-degree plasma for 300 seconds by 2026. Data from the operational campaign will be directly relevant to ITER, which will operate a tungsten divertor under similar plasma conditions in terms of shape and structure.
This testing campaign will continue through February 2024. Read more about the plans in this article in English on the KFE website, or in Korean in the Chosun Biz.
