Voters in the region overwhelming supported two nonbinding referenda Tuesday which back universal health care and control greenhouse gases.

In a half-dozen Pioneer Valley communities, residents were asked whether they wanted to instruct their state representatives to support steps to create a single-payer health care system as a basic human right and to work to reduce greenhouse gases by 80 percent by 2020.

In all, voters in 13 communities found the health care question on their ballots, placed by Mass-Care of Boston, a 13-year-old group that supports a single-payer health insurance system.

Tallies in support of the health-care question in area towns were as follows: Amherst (9,412-1,624), Granby (2,025-947), Hatfield (1,355-512), Northampton (12,078-2,189), Southampton (1,975-958) and Westhampton (698-265). The question was before voters in the 2nd Franklin District, the 1st Hampshire District and the 3rd Hampshire District.

The other question asked if voters wanted to instruct their state representatives to work to reduce greenhouse gases, phase out tax incentives for projects that are considered "energy intensive" and to back job programs in renewable energy.

Results in the communities that voted on the question ran strongly in favor, as the following list shows: Amherst (9,981-1,140), Granby (2,217-771), Hatfield (1,429-444), Northampton (12,606-1,718), Southampton (2,061-851) and Westhampton (731-236).

The question was before voters in the 1st and 3rd Hampshire districts.

Both are advisory only.
