Summary of the article " Research on global sun block needed now" ( Keith, Parson, Morgan, 2010) ( Chung's post)

In recent years, geoengineering has been considered as one possible way to mitigate climate change, however, little research has been carried out by scientists and world's countries. The article aims at urging countries to conduct further research of solar-radiation management (SRM) before making any decisions towards this method.

In the first part of the article, the authors show the evidence of Mt Pinatubo as an illustration of the effectiveness and swiftness of utilizing SRM. However, the article also shows notification about the political risks and different damages between countries. It is recommended that countries should facilitate further complicated research on SRM to get a deeper understanding of SRM in order to negate critical environmental risks.

Then in the second part, the authors point out the current shortage of information as well as research funding for SRM. This fact may lead to the careless use of SRM in emergency situations while full understanding has not yet been obtained. The authors also suggest that simultaneous research in conducting SRM experiments and defending the environment against risks should be noticed by international leaders.

Ultimately, the article shows that the primary problem for SRM is how to maintain the consensus between countries towards the utilization of SRM. In addition, SRM also should not be governed by any countries. On the other hand, international cooperation will be a better way of approach. Simultaneously, the article demonstrates that it will be more advantageous for us if we know early about the hazards that SRM can cause.

To sum up, throughout the article, the authors suggest that responses towards mitigation of climate change should be in two ways: further evaluation of SRM and at the same time, reducing gas emissions(Keith, Parson, Morgan, 2010).
