Climate change could be even worse for Boston than previously thought -0:40

The consequences of climate change on Boston are expected to be far more calamitous than previous studies have suggested, a new report commissioned by the city says.
In the worst-case scenario, sea levels could rise more than 10 feet by the end of the century — nearly twice what was previously predicted — plunging about 30 percent of Boston under water. Temperatures in 2070 could exceed 90 degrees for 90 days a year, compared with an average of 11 days now.
And changes in precipitation could mean a 50 percent decline in annual snowfall, punctuated by more frequent heavy storms such as nor’easters.
