Climate change impacts, such as severe drought, sea-level rise, and shifting seasonal patterns, will affect people everywhere. So it’s fitting that the new Paris Agreement places unprecedented importance on actions needed – both nationally and globally – to help people adapt, and solidifies expectations that all countries will do their part to promote greater climate resilience. It also recognizes that even the greatest resilience may not completely prevent harm to life and property, and that the global community must find ways to address “loss and damage” in cases where impacts are beyond the limits of adaptation.

The good news out of Paris is that the world is finally getting serious about reducing greenhouse gas emissions. Here are a few reasons to cheer and one quibble.

The agreement coming out of the COP-21 negotiations gave breakthrough recognition to the concept of “loss and damage,” sorting through thorny discussions and politically charged negotiating positions. These positions revolved around liability and compensation, which developing countries called for but developed countries were unwilling to have included in the agreement.

One of the hidden costs of climate change is the displacement of millions of people in some of the poorest regions of the globe. The existing international refugee regime is ill-suited to cope with those seeking refuge from environmental disasters. Countries must get serious about developing coordinated plans to address the issue, lest they be caught by surprise when another humanitarian crisis hits.

Last month, for the first time, 195 countries formally agreed to take steps to slow and eventually reduce carbon emissions. “This is potentially one of the most important things that’s ever been done for your children, your grandchildren…and their welfare in the future,” said Andrew Light, professor of public philosophy at George Mason University. [Video Below]

The nations of the world may have finally solved the thorniest problem in international relations and now we need to figure out practical solutions, said a panel of experts at the Wilson Center on December 16.

Security was inseparable from the climate talks in Paris, from the safety of conference participants to how climate change impacts the stability of nations.

The new climate deal coming out of Paris commits governments to hold the rise in average global temperatures to “well below” two degrees Celsius compared to preindustrial levels. An important dimension of this agreement calls for subsequent work on limiting the increase to 1.5 degrees. This is an important win for islands and other low-lying countries, and for humanity.
