Rahmstorf reckons that climate scientists have communicated their work quite well, particularly through the IPCC. While 2010 is the UN year of biodiversity, the biodiversity community has "not yet managed to get as much high-level attention to the biodiversity crisis; it is only now calling to set up something like the IPCC for biodiversity". On the other hand, "climate science could still do a lot better if more climate scientists get involved, take an interest in public understanding of science and educate themselves more about how to effectively work with the media". Rahmstorf reckons that "too many scientists are still stuck in the ivory tower and – for example – shrug off and ignore wrong media reports about climate science, rather than recognizing that public perception matters and that they should not leave the public debate to people with a political agenda".

The last word goes to de Boer: while the Copenhagen negotiations "didn't produce the final cake", they did leave countries "with all the key ingredients to bake a new one". Although the proof of the pudding, as they say, is in the eating.
