It's Not Just You: July's Heat Broke Records

July was the warmest month on record in Boston since record-keeping began in 1872.

Portland, Maine, and Hartford, Connecticut also broke average heat records.

Climate scientists expect more record-breaking heat events in the future.

The temperature takes a toll — like at Vernon Family Farm in New Hampshire, where more than 400 chickens died of heatstroke.
