Climate and Energy: Combatting Global Climate Change

Protecting the Environment and Reversing Climate Change Abroad: November 2008 to January 2017

“I refuse to condemn your generation and future generations to a planet that's beyond fixing.”

From the day he first took office in January 2009 to the day he left office in January 2017, President Barack Obama believed that no challenge posed a greater threat to our children, our planet, and future generations than climate change. Indeed, as he saw it, acting on climate change was a moral obligation of the present, not a distant problem of the future. And that’s because, long before President Obama assumed office, the planet was already changing in ways that – if left unchecked – would have a profound impact on all of humankind. The scientific evidence accumulated and reviewed over the past several decades showed unequivocally that the planet was warming, primarily due to human activities over the past 50 years. As a result, summers were becoming longer and hotter. Winters were becoming shorter and warmer. Ice on land and in lakes and seas was melting. Global sea levels were rising. And from storms, hurricanes, and heavy downpours to droughts, fires, and floods, extreme weather was becoming more frequent and intense. Simply put, climate change was dramatically altering the world – and altering it in ways detrimental to life on earth. At the same time, U.S. emissions were projected to increase indefinitely when the President took office.

This timeline tells the story of how the President and his team galvanized international action to address climate change. It documents the decisions made, as well as the challenges faced, by the Administration in its efforts to protect the air we breathe, the water we drink, and the land that supports and sustains us. Above all, the timeline shows that – from leading by example at home to building a coalition abroad – the President worked diligently to bring together the nations of the world to tackle the greatest environmental challenges of our time.

“So I believe this moment can be a turning point for the world. We’ve shown that the world has both the will and the ability to take on this challenge. It won’t be easy. Progress won’t always come quick. We cannot be complacent. While our generation will see some of the benefits of building a clean energy economy -- jobs created and money saved -- we may not live to see the full realization of our achievement. But that’s okay. What matters is that today we can be more confident that this planet is going to be in better shape for the next generation. And that’s what I care about. I imagine taking my grandkids, if I’m lucky enough to have some, to the park someday, and holding their hands, and hearing their laughter, and watching a quiet sunset, all the while knowing that our work today prevented an alternate future that could have been grim; that our work, here and now, gave future generations cleaner air, and cleaner water, and a more sustainable planet. And what could be more important than that?”
