Smart highlighted the concept of wet bulb temperature and its implications for human health in the context of climate change, a critical aspect given the increasing frequency of extreme heat events. The presentation was rich in data, featuring a graph that showed the stability of global average temperatures over millennia and how this stability has been integral to the development of societies. This set the stage for discussing the unprecedented nature of current climate change and the necessity for societies to adapt. The significance of heat as a key aspect of climate change was emphasized, with an explanation of how warmer air can carry more moisture, potentially leading to increased drought likelihood.

The committee also examined the impact of rising temperatures on various systems that have been designed based on assumptions of climate stability. These include storm sewers, power systems, and cultural practices, all of which may need updates to cope with changing climate conditions. The need to revise the USDA plant hardiness zone map according to climate model data was discussed, highlighting its relevance to agricultural practices, such as crop insurance in the United States.

The session further delved into the potential ramifications of climate change on different regions, with a focus on the differences between the Western and Eastern United States due to geographical and climatic factors. The committee explored global maps showing trends in warming scenarios and the likelihood of drought, emphasizing the impact of heat and humidity on different regions. This geographic focus brought to light the increasing likelihood and severity of extreme weather events, such as droughts and big storms, associated with global temperature rise.

A representative from Probable Futures.org also contributed to the discussion, stressing the importance of understanding climate boundaries and utilizing science to live well in a changing climate. The conversation covered the stability of the climate over different time periods and the impact of human activity on this stability. It touched upon the implications for food production, water sources, and industry solutions.

The meeting provided a platform for examining local efforts aimed at building climate resilience. The strategic thinking of New Bedford’s chief resiliency officer and the engagement of grassroots organizations in the area were mentioned as positive steps towards local adaptation and preparedness.

The series of presentations and discussions at the Westport Climate Resilience Committee meeting highlighted the interconnectedness of global societies in addressing climate challenges. It also stressed the need for integrated climate considerations into decision-making processes and planning for potential challenges.
