There’s no such thing as a free lunch.

IntroductionWhen you change the climate you change

every thing.It effects people and nature in countless ways.Impact on ecosystems, economics and

communities.

Negative Impacts of CCPhysical impacts Raise in global temperature• Heat weaves Rising sea level• Melting polar ice• Loss of mountain glaciers and snow pack• Expansion of the oceans Increase in extreme events• Stronger hurricanes• More droughts and flooding

Ecological ImpactsShifts in species ranges and phenology• 130 species, both plants and animals have responded

to earlier spring warming• 1400 species are listed endangered due to CC- Red

list Wildfire, drought and insects• Increase in global temperature• Drying of spring, ground water depletion

Invasive speciesAgricultural shiftsOcean acidification• Emission of carbon dioxide• Dissolve of carbon dioxide in seawater

Socio- Economic ImpactsEquity and InequalityHealth• Infectious diseases• Water borne diseases• Food borne diseases• Vector borne disease• Respirator illness• Diabetes/Hypertension/Obesity

Social conflictCommunity will be forced to relocateRisk and property householdsAgriculture, transportation and food

.

Positive Impacts of CCFewer winter deathsLower energy costsBetter agricultural yieldsProbably fewer droughtsMay be richer biodiversity
