Saying the 12 hottest years on record have taken place in the past 15, Obama issued an ultimatum to Congress on climate change. He vowed to take action to confront climate change through presidential executive orders unless Congress enacts legislation.
US Senator Marco Rubio, a rising Republican star who could run for president in 2016, accused Obama of being too fond of big government.
“I hope the president will abandon his obsession with raising taxes and instead work with us to achieve real growth in our economy,” Rubio said in the formal Republican response to Obama’s speech.
