Increased deaths to heatwaves - 5.74% increase to heatwaves compared to 1.59% to cold snaps (Medina-Ramon 2007) Increased heat stress in humans and other mammals (Sherwood 2010) Spread in mosquite-borne diseases such as Malaria and Dengue Fever (Epstein 1998) Increase in occurrence of allergic symptoms due to rise in allergenic pollen (Rogers 2006)
Ocean Acidification
Substantial negative impacts to marine ecosystems (Orr 2005, Fabry 2008, Kroeker 2010) Inhibiting plankton development, disruption of carbon cycle (Turley 2005) Increased mortalities of sea urchins (Miles 2007) Threat to fish populations (Munday 2010)
Economical
Economic damage to poorer, low latitude countries (Mendelsohn 2006) Billions of dollars of damage to public infrastructure (Larsen 2007) Reduced water supply in New Mexico (Hurd 2008) Increased risk of conflict (Zhang 2007) including increased risk of civil war in Africa (Burke 2009) Drop in primary productivity due to unprecedented warming at Lake Tanganyika (Tierney 2010)
Sea Level Rise
Hundreds of millions displaced within this century (Dasgupta 2009) Coastal erosion in Nigeria (Okude 2006)
Arctic Melt
Loss of 2/3 of the world's polar bear population within 50 years (Amstrup 2007) Less compacted ice, hazardous floes and more mobile icebergs posing increased risk to shipping (IICWG 2009) Drying of arctic ponds with subsequent damage to ecosystem (Smol 2007)
Im going to be blunt in saying that if you think that global warming is a good thing you have rocks in your head.
