About biodiversity more than AGW, but not completely unrelated:

Biodiversity nears 'point of no return'The decline in the world's biodiversity is approaching a
point of no return, warns Hilary Benn. In this week's Green Room, the
UK's environment secretary urges the international community to seize the
chance to act before it is too late.
In 2002, the world's governments made a commitment to significantly reduce the rate of biodiversity loss by 2010.
Although it is
hard to measure how much biodiversity we have, we do know these
targets have not been met. [

…
Mechanisms now exist for research, monitoring and scientific assessment of biodiversity, although we now need an Intergovernmental Panel on Biodiversity and Ecosystem Services to oversee progress …
Tipping point; unknown significance; targets?
Don’t tell me, would that be
an Intergovernmental Panel on Biodiversity and Ecosystem Services to oversee progress “...in the same way the IPCC does for climate change”?

(Yes, the article does say this)

Climate change and biodiversity are inextricably linked.
Let’s examine this.
- There is a strong argument that atmospheric CO2 doesn’t result with global warming (no higher temps [and ice ages] when the level was many, many times higher).
- We know we need CO2 to live (food comes from carbohydrates, that coming from atmospheric CO2), so it follows that more CO2 results with greater biodiversity (we’ve not had creatures anything like dinosaurs for a while).
Atmospheric CO2 sustains our ecosystem.
