Climate change has already brought record high and low temperatures, impacting everything from baseball (we hosted the hottest-ever World Series in 2017) to heating and cooling bills for residents and businesses. Urban residents also face exacerbated health impacts due to the "urban heat island effect," where commonly used materials, such as conventional pavement, absorb and retain heat.
Climate change also worsens existing inequities in specific communities:
The County will consider climate adaptation and resilience in all future planning and development decisions. We will prioritize green infrastructure and biodiversity preservation that will support a healthy, resilient environment while addressing inequities and public health. The dangers we face from climate change are immense. Every action we take now to protect our homes, communities, and infrastructure should better
prepare us for the future and protect us against climate risks and their disproportionate impacts.
