摘要：Lemons & Brown (2011, this issue) contend that convincing scientific evidence about the threats posed by global climate change (GCC) and their anthropogenic nature have been available over the past few decades through the 4 IPCC reports and a host of other studies. It is also amply clear that any procrastinating attitude in tackling this challenge will mean far-reaching adverse consequences for which the present generation, as the trustee of the global environment and its resources, cannot avoid responsibility. Besides, Lemons & Brown (2011) are also right to point out that GCC also gives rise to several ethical questions, firstly because the nations likely to be worst-affected are among the least contributors to greenhouse gas (GHG) emissions; secondly GCC affects people who are among the poorest; and thirdly because the global scope of the impacts of GCC can only be mitigated through co-operative action from multiple governments.
