Document Summary

Influences land climate: nutrient rich water more phytoplankton growth = removing carbon from atmosphere and increasing oxygen. Increasing co2 has increased the uptake from carbons sinks like ocean which has impacts of its own: methane lives longer in atmosphere than co2 just as dangerous. Increased warming increase evaporation meaning more water in atmosphere which only makes it hotter: greenhouse gases help create global warming radiation hits them so more energy being stored in the atmosphere and reflected onto the earth. Infrastructure protection: flood mitigation, emergency responses, business continuity plans, community engagement, mitigation how to reduce the severity, energy efficiency, renewable energy - solar, geothermal, hydro or wind, combined heat and power, sustainable transportation, methane capture and use. Industrial process improvements: carbons sinks sequestration (ocean fertilisation put iron in ocean supposed to promote phytoplankton to photosynthesise and take co2 out of atmosphere)
