Climate change is caused by an increase in the concentration of atmospheric greenhouse gases. Potential climate change impacts in Northern California include declining water supplies, spread of disease, diminished agricultural productivity, sea level rise, and increased incidence of wildfire, flooding, and landslides. Like many communities, Mill Valley is addressing these potential impacts by thinking differently about its resources, taking actions to reduce the community’s contribution to greenhouse gas production, and identifying strategies to allow the community to adapt to potential foreseen changes. – Mill Valley Climate Action Plan
