GEOG 1972 Lecture Notes - Lecture 26: Food Security, Greenland Ice Sheet, Arctic Ocean
Document Summary
Monitor and attribute cause of transformation (co2 loadings) Calculate total use to meet targeted allowable harm or effort to restore previous conditions. Since this is a commons/collective action problem: Parties work out ways to divide up allocations. To set the target level, we need a process. Make it like many other environmental decisions. Sets targets for ghg reductions to keep net warming below that level. Monitor and re-assess as change and adaptation/development proceeds. Geophysical impacts like melt of arctic sea ice or greenland ice sheet. Bio-physical impacts like loss of valued ecosystems. Human impacts like increased disease, loss of food security (e. g. , mass starvation), displacement of people. Nation-state: each negotiating entity defines dangerous to them. Local level: dangerous to a single village to city. Moving down this scale implies defining smaller climate change as dangerous: But: adaptatio(cid:374) a(cid:374)d preparatio(cid:374) for (cid:272)li(cid:373)ate (cid:272)ha(cid:374)ge alters the (cid:862)da(cid:374)gerous(cid:863) threshold. Adaption is adjusting to that which you cannot mitigate.
