The COP16 climate talks in Cancun have entered the final stretch, but the prospect that the conference will conclude with a substantial agreement is more remote than ever. Generelly there's a sense among participants that there's increasing urgency to the issue of climate change – and a degree of astonishment at the declining importance of the topic in the media and in public perception – no matter if it's in the US or across the pond.

Among those, that are most vociferously campaining for rapid action on climate change is 350.org, a global network of pressure groups and NGOs. We talked to 350.org's Mexico coordinator Marcelo Quintanilla, who believes that there's been too much talk but that  the Cancun conference nevertheless offers a big chance for change.

Second, there's Dave Jones who works to "raise the environmental IQ of America" – the chosen tagline of his science-based communications agency StormCenter – dedicated to driving the urgency of climate change home to a US public increasingly unfazed by the issue. At the Cancun climate talks he runs a multimedia display in the US pavilion to educate visitors about the impact of climate change. Just two findings are: The oceans have measurably warmed down to depths of 300 meters and storms won't necessarily become more frequent but very much more destructive, he says.
