Climate Change Maui: There is a lot of confusion about climate change. There are anthropogenic (man-made) factors the affect climate, like greenhouse gasses, and deforestation and pollution. This is a worldwide problem but has to be managed locally as well. Reducing our carbon footprint using renewable resources like solar and wind energy, as well as recycling and reusing materials rather than throwing materials away after a single use. also being mindful of not causing harm to the ecosystem by over using toxic agricultural chemicals, Also eating less meat would be some major steps in reducing greenhouse gasses and slowing Global Warming.
How climate change affects Maui, we are an island so sea level rise is a problem, There is forecast sea level rise globally with an average of 1.8mm per year. Kahului Maui has a forecast annual sea level rise of 2.1mm per year. which is very small annually by adds up over the longer timescale. Here is an inundation map (below) of Kahului after the 1-meter sea level rise. At current rates, this could be in about 400-500 years. As you can see Kite beach is still there. The negative effects of climate change should not be underestimated. Severe weather and crop failures will have a dramatic effect on the way we live, Storm damage to property and the relocation and reinforcing of infrastructure will be very disruptive and extremely expensive.
BEACH LOSS: Beach Loss is not solely attributed to sea level rise, it is more directly influenced by man-made problems like destruction of wetlands, destruction of sand stocks, covering shoreline dunes with development, 70 years of sand mining (removal of sand and coral from beaches and nearshore waters), and shoreline hardening. These are things that we can more easily remediate, at least in the short-term.
Beach restoration, sand supplementation, Dune stabilization with native plants, sand fencing, limiting overuse of the nearshore zone, and of course shoreline setback regulations for new structures being constructed. Shoreline areas need to be preserved for their vital role in protecting our island from shoreline retreat. Beach loss/sand-loss itself is just the symptom of the underlying problems.
Coral Reef Destruction and Degradation: Coral Reef Protects the shoreline from wave action and allows the build up of sandy beaches. Coral Reefs also provide the raw materials for Coral Sands that most Maui beaches are primarily made of. Healthy Coral needs to be protected, appreciated and valued for its role in coastal protection and beach preservation.
Loss of Beach Access: A more pressing made-made issue is Loss of Beach Access, where less public ocean access is available. This is due to developers, and public planners failing to protect ocean access points. This is the biggest immediate threat the ocean users face here on Maui.
Please ask the Maui Mayor to stop the sale of Maui sand by enforcing the County code and revoking the grading permit. Now that the county has admitted the landowner needs a conditional use permit and a special use permit to operate, they can easily revoke the grading permit. He has the power to stop this NOW, rather than require new legislation from council, which could take months. By then the sand could all be gone! Ask that the Administration write the legislation, approved by their corporation counsel, and forward it to the council. We ask that steps be taken to protect this area as a natural and cultural reserve.
