California Governor Jerry Brown is favoring the goals of US President Barack Obama and it seems that he has found a sweet spot in climate-change communication. Some top masterminds of brown are farming two irreconcilable rhetorical strategies: a fateful doom and gloom, and sunny, pragmatic optimism.

President Obama has departed from the US to attend the summit despite lack of Republican congressional support. President Obama will be standing in support of the emerging multi-national treaty that aims to reduce greenhouse-gas emissions.

Gov. Brown’s presence at the Paris climate summit shows that the largest US state will help in limiting the global warming to below two degrees Celsius.

Brown, who once called himself the president of California, said states are compelled to act on climate change because congressional Republicans are tying Obama's hands.

Brown said, “We are trying to spur on the nation-states. We need to work from the bottom up. The United States is somewhat of an outlier because of bitter opposition from Republicans in Congress to any kind of climate leadership. The Republicans want Obama to fail”.

The Obama administration during the Paris climate summit pledges to reduce the US emissions by as much as 28% in the coming decade. And to submit this goal as part of the treat would require approval from the Senate, which is a tough task.

The Republicans at the Senate hold 54 of 100 seats and out of those many are still skeptical about the human-caused global warming and also believe that limiting use of fossil fuel will largely hit the economy.
