Even if Democrat Joe Biden wins the White House, he would struggle to pass sweeping legislation to combat global warming if Republicans maintain Senate majority

Nov 4 (Reuters) - A failed Democratic drive to gain control of the U.S. Senate could reduce the prospects for aggressive legislation to combat global climate change, even if Democratic presidential candidate Joe Biden were to win the White House.
By early Wednesday morning, the presidential race between Biden and Republican President Donald Trump was too close to call, but emerging results from down-ballot races pointed to Republicans maintaining a majority in the Senate.
"I don't see any way for comprehensive climate legislation to get through the Senate. Off the table for at least two more years even if Biden squeaks out a victory," said Scott Irwin, an agricultural economist at the University of Illinois.
"No one is going to have an overwhelming mandate," said Ed Hirs, economics professor at the University of Houston.
Still, Scott Segal, the co-chair of the Policy Resolution Group at lobbyist firm Bracewell in Washington, said Biden's more than three decades in the Senate and friendships he has developed there could help him develop a middle path for passage of at least some modest legislation on energy and climate.
"I'm not trying to lionize Joe Biden here, but I will tell you there are few people who would fit that bill," Segal told reporters in a teleconference.
Biden has promised to guide the United States economy to net-zero emissions by 2050 to fight global warming if he is elected, a pledge that would require sweeping legislation.
Trump, meanwhile, has downplayed the risks of climate change and rolled back a slew of climate and other environmental protections to boost U.S. drilling and mining - an approach backed by many Republican senators.
He also withdrew the United States from the international accord to fight climate change called the Paris Agreement, an exit that formally took effect on Wednesday.
