California took some of its most aggressive steps yet to fight global warming as lawmakers passed a flurry of new climate bills late Wednesday, including a record $54 billion in climate spending, a measure to prevent the state’s last nuclear power plant from closing, sharp new restrictions on oil and gas drilling and a mandate that California stop adding carbon dioxide to the atmosphere by 2045.

The bills, passed around midnight at the end of a frenzied two-year legislative session in Sacramento, marked a victory for Gov. Gavin Newsom, a Democrat who has sought to portray himself as a climate leader as he has raised his national profile and begun drawing speculation about a possible White House run.

Mr. Newsom upended the legislative session in mid-August when he urged lawmakers to pass several major new climate bills. In the end, all of his proposals passed but one: a bill to strengthen the state’s 2030 target for slashing planet-warming greenhouse gas emissions, which fell short by four votes in the State Assembly.

“Together with the Legislature’s leadership, the progress we make on the climate crisis this year will be felt for generations and the impact will spread far beyond our borders,” Mr. Newsom said in a statement.
