Climate Change Threatens All Americans

Climate change is a national security issue. The longer we wait to act, the harder it will be to mitigate and respond to its impacts. U.S. leadership alone will not guarantee global cooperation. But if we fail to take action now, we will have little hope of influencing other countries to reduce their own harmful contributions to climate change, or of forging a coordinated international response.

We must also help less developed countries adapt to the realities and consequences of a drastically changed climate. Doing so now will help avoid humanitarian disasters and political instability in the future that could ultimately threaten the security of the U.S. and our allies.

But most importantly, we must transcend the political issues that divide us – by party and by region – to devise a unified American strategy that can endure and succeed.

We, the undersigned Republicans and Democrats, believe Congress working closely with the Administration must develop a clear, comprehensive, realistic and broadly bipartisan plan to address our role in the climate change crisis. WE MUST LEAD.
