Document Summary

Climate change global surface temperature is on the rise. This is especially noticeable since the onset of the (cid:858)g(cid:396)eat a(cid:272)(cid:272)ele(cid:396)atio(cid:374)(cid:859) as lo(cid:374)g as (cid:272)a(cid:396)(cid:271)o(cid:374) emissions continue/ increase we can expect climate change to continue. *nature (2013) global temperatures are close to an 11, 000 year peak* The consequences are that the arctic / antarctic/ greenland ice sheets are melting. By the end of the century it is predicted that we will rise 1 metre sea level. Ie) the pacific island are only about 2 m about sea level.

In time to keep civilization running: in time to stop further climate change. It should also be noted that more evaporation means that there is more water vapour in the atmosphere. Water vapour traps heat further which contributed to rising heat. More drought also means increased fire and insect outbreaks. Burning adds more atmpsheric carbon which in turn adds more heat.

Comprehensive Final Essay: Perverse Subsidies
The negative effects of perverse government subsidies and how they directly compound other problems have been mentioned throughout the textbook and in Myersâ guest essay âPerverse Subsidiesâ. In order to answer the questions below, youâll be gathering your information from various chapters. If you remember sufficient detail without having to look things up, you must say so (âfrom memoryâ). Otherwise, please cite all pages consulted.

NOTE: I am NOT asking for a recap of all the environmental and social problems associated with agriculture, fisheries, mining, etc. (That would be a very long discussion!) Each chapter section describes information specific to subsidies for each industry. Please summarize in your own words. (Total 5 points) Once again, Iâve assigned the number of points required to minimally answer each topic, but extra credit may be earned. This is your chance to pull ahead with your insight into subsidies!
