Gasoline prices have dominated the Houston-area and national news as prices at the pump continue to climb toward $4 per gallon.

In Houston, gasoline prices are up a penny overnight to $3.50, or roughly 45 cents higher than they were last year. Nationally, the pump prices rose three cents overnight to $3.64.

Gasoline prices have risen 25 cents over the past month, and they’ve been steadily rising since New Year’s Day. Analysts said they are likely to continue to rise through the summer, and there isn’t an easily solution.
