"President Barack Obama and Congress are headed for another power clash on the international stage, as key Senate Republicans challenge his efforts to forge a global pact on climate change," according to The Wall Street Journal .
"The White House considers the agreement with nearly 200 nations a historic opportunity to reduce greenhouse-gas emissions world-wide. But some GOP senators view it as executive overreach, and they are quietly considering ways to warn other countries that the president doesn’t speak for them and may not be able to deliver on his promises to slash emissions."
"Administration officials have signaled optimism in recent weeks that climate talks are on track, with countries working toward completing a deal in December in Paris. They have expressed confidence that laws already on the books will allow them to move ahead with a plan submitted to the United Nations to cut greenhouse gases in the U.S. by nearly 30% by 2025 based on 2005 emission levels."
