their excellent Perspectives article in this issue, Ramanathan and Feng (R&F) sound a harsh
wake-up call for those concerned
about anthropogenic climate change: the authors maintain that the greenhouse gas (GHG) emissions of the past have already
loaded the Earth System
sufficiently to bring about
disastrous global warming. In other words, the ultimate goal of climate
protection policy, as stipulated by the United Nations Framework Convention on
Climate Change (UNFCCC), appears to be a delusion.<o:p class=""></o:p></span></p>
