Belfast — The city's Climate Crisis Committee and Belfast Free Library hosted a talk with four panelists March 29 called "After Summit: How Do We Get to Carbon Neutrality by 2045?" which looked at the relative merits of natural gas and heat pumps as heating sources. It was prompted by Summit Natural Gas's proposing, then rescinding, its estimated $90 million natural gas pipeline expansion through the Midcoast. The roughly 30 people who attended the forum had the chance to ask panelists questions and share comments.
