Meeting with world leaders at the United Nations’ Climate Change Summit, President Obama said “no nation, however large or small, wealthy or poor, can escape the impact of climate change.”

The effects of climate change can be reversed, Obama said. While the United States may have not done enough in the past, “it is a new era. … I am proud to say that the United States has done more to promote clean energy and reduce carbon pollution in the last eight months than at any other time in our history.”

The United States is increasing its investment in renewable energies and will work with other nations to seek other solutions.

“Because no one nation can meet this challenge alone, the United States has also engaged more allies and partners in finding a solution than ever before,” Obama said. The president acknowledged that international cooperation on the topic is challenging, but that “difficulty is no excuse for complacency.”

What do you think - can the effects of climate change be reversed? And do you believe governments will work together to make this happen?
