Summary of predicted climate effects on species Source: Foden, Mace et al. 2009 IUCN

CLIMATE CHANGE PREDICTIONS BASED ON IPCC EMISSION SCENARIOS Increases in surface air temperature, IPCC (2007) WGI: The Physical Basis of Climate Change A2 Medium/high emissions scenario “Business as usual” B1 Low emissions scenario A1B Medium emissions scenario
3
Vulnerability framework Levels of vulnerability used to grade species

11
Two fundamental concerns… Are we sufficiently aware of the global warming threat? Are we sufficiently responding to that threat?
12
What is a safe temperature/CO 2 level? Current focus is all on 2 o C (~450ppm CO 2 )
