OP-ED: Sen. Brownsberger Looks at Local Flooding Risks From Climate Change
|
As a legislator, I’ve been concerned to reduce our contributions to climate change. Over the last few weeks, I’ve been trying to better understand the local flooding risks caused by the climate changes we seem unable to prevent. It’s hard to know how much the seas are going to rise. First, no one knows how much the people of the world will be able to reduce carbon emissions. Second, even within a given emissions scenario, the uncertainties are considerable. For example, if we just assume continually growing emissions, the estimates of probable local sea level rise vary by a factor of two from 3.2 feet to 7.4 feet by 2100. Much of Boston lies quite low, so these uncertainties matter.
