Climate Change 101 :Climate Change 101 Greenhouse Gases
carbon dioxide
methane
water vapor
nitrous oxide
ozone
halo carbons The gases that make up the atmosphere act as a “greenhouse” and trap heat from the Sun and activities on Earth, preventing it from escaping into outer space.
Naturally occurring greenhouse gases are what keep our planet warm enough for life to exist.
Under natural conditions, CO2 is released and recaptured by the atmosphere, ocean, and vegetation. This is known as the carbon cycle. :Under natural conditions, CO2 is released and recaptured by the atmosphere, ocean, and vegetation. This is known as the carbon cycle.
When too many greenhouse gases are released, too much heat is trapped into the Earth’s atmosphere.This causes global temperatures to rise and can trigger climate change. :When too many greenhouse gases are released, too much heat is trapped into the Earth’s atmosphere.This causes global temperatures to rise and can trigger climate change.

Greenhouse Gases Sources :Greenhouse Gases Sources IPCC Synthesis Report 2007
Global Climate Change Impacts on Hawaiian Ecosystems :Global Climate Change Impacts on Hawaiian Ecosystems IPCC Synthesis Report 2007 The Hawaiianarchipelago is too smallto register on mostglobal climate models,which begs the question:Just what will happen here?
Global Climate Change Impacts onHawaiian Ecosystems :Global Climate Change Impacts onHawaiian Ecosystems Ambient Temperature Global average ambient temperature increase approximately 4.1oF by 2100
Temperature in Hawai‘i has been rising over the last 100 years with the greatest increase after 1975
The rate of increase at low elevation is below the global average
At high elevations, the rate of increase greatly exceeds the global rate Ocean Temperature By 2100 Hawaiian waters may increase from 73 oF to 79 oF
Widespread bleaching of coral likely
Alien algal blooms likely to further impact corals
Coral disease incidence will rise in frequency and magnitude
Slide 10:IPCC Synthesis Report 2007
Global Climate Change Impacts onHawaiian Ecosystems :Global Climate Change Impacts onHawaiian Ecosystems Sea Level Rise Melting ice + thermal expansion = a predicted rise of two to three feet this century (IPCC, 2007)
Flooding of low-lying coastal areas
Saltwater intrusion
High wave inundation
Accelerated beach erosion
Global Climate Change Impacts onHawaiian Ecosystems :Global Climate Change Impacts onHawaiian Ecosystems Ocean Acidification CO2 dissolves into the oceans and acidifies the surface waters
By 2070, marginal coral conditions for Hawai‘I
Acidification will halt growth of coral reefs, mollusks, and plankton disrupting the marine food web Pteropods are zooplankton with calcium carbonate shells that dissolve in acidic water.

Hawai‘i is the showcase – Pacific Islands Climate Change Cooperative (PICCC)
Climate Change Policies :Climate Change Policies Pacific Islands Climate Change Cooperative
Interdisciplinary, but with a focus on native species and ecosystems
Focusing first on Hawai‘i then greater Pacific Island Region
Science and technology clearinghouse
Climate scenarios
Adaptation assessment and planning
Monitoring and adaptive management
Why We Care :Why We Care Hawaiian native species and their habitats already are impactedby many stressors, including global climate change.
Recommendations :Recommendations Establish a Hawai‘i Climate Change Coordinating Council
Improve our understanding of how Hawai‘i's climate may change
Assess the likely impacts of climate change on important Hawaiian resources Develop a plan for how Hawai‘i will adapt to a changing climate
Integrate existing efforts into a coherent framework
Engage the public now on land planning, water use, and natural resources management and climate change
Create culturally appropriate management strategies
What You Can Do :What You Can Do Reduce your carbon footprint
Support conservation of native ecosystems
Engage in climate change policy processes
