The Casco Bay region is vulnerable to seven important climate stressors highlighted by the US Environmental Protection Agency: warmer summers; warmer winters; warmer waters; increased drought; increased storminess (evident in higher total precipitation, frequency and intensity); sea level rise; and ocean acidification (US EPA 2014). These climate stressors do not operate in isolation. Compounding their impacts are factors such as population growth, habitat fragmentation and destruction, and resource depletion that can further tax ecosystems and species.
