“Climate change is real, regardless of what others may say,” he added.

Mike Gabbard, the chairman of the state senate’s agriculture and environment committee was more blunt.

“I don’t think it’s a surprise for any of us to be here, when the president of the United States had climate change removed from the White House website,” he said.

Many references to climate change were removed from the White House site in January, as part of the routine digital turnover from one administration to the next. In April, the Environmental Protection Agency removed much of the climate change information from its website, saying in a news release that the updates were made to “reflect the approach of new leadership.”

Hawaii is one of more than 10 states that have joined the U.S. Climate Alliance, a coalition committed to upholding the Paris accord despite the federal government’s withdrawal from it. The alliance, announced by the Democratic governors of California, Washington and New York last week, also includes Minnesota, Virginia, Massachusetts and Vermont.

Those states are working parallel to a broader effort being coordinated by Michael Bloomberg, the former mayor of New York City, of cities, corporations and universities that together will submit a plan to the United Nations pledging to meet the targets for the United States specified by the accord. It is unclear how exactly that submission will take place.
