The American Party

James Hansen

My remarks when receiving the Ridenhour Courage Award were written in Union Station on my way to the event. But my concluding comment -- that we are near a point when the American people should contemplate a centrist third party -- was not an idle spur-of-the-moment reflection.

I was in government 40 years, long enough to understand how aging organizations can evolve into self-licking ice cream cones, organizations whose main purpose becomes self-perpetuation rather than accomplishment of their supposed objectives. The public can see this tendency in our politicians, our Congress, and our major political parties.

Our government has failed to address climate, energy, and economic challenges. These challenges, addressed together, actually can be a great opportunity. Our democracy and economic system still have great potential for innovation and rapid adoption of improved technologies, if the government provides the right conditions and gets out of the way.

Doubling Down on Our Faustian Bargain

by James Hansen, Pushker Kharecha, Makiko Sato

Faust in his Study by Rembrandt

Humanity is doubling down on its Faustian climate bargain by pumping up fossil fuel particulate and nitrogen pollution. The more the Faustian debt grows, the more unmanageable the eventual consequences will be. Yet there are plans to build more than 1000 coal fired power plants and plans to develop some of the dirtiest oil sources on the planet. These plans should be vigorously resisted. We are already in a deep hole -- it is time to stop digging.

Humanity's Faustian climate bargain is well known. Humans have been pumping both greenhouse gases (mainly CO2) and aerosols (fine particles) into the atmosphere for more than a century. The CO2 accumulates steadily, staying in the climate system for millennia, with a continuously increasing warming effect. Aerosols have a cooling effect (by reducing solar heating of the ground) that depends on the rate that we pump aerosols into the air, because they fall out after about five days.

Aerosol cooling probably reduced global warming by about half over the past century, but the amount is uncertain because global aerosols and their effect on clouds are not measured accurately. Aerosols increased rapidly after World War II as fossil fuel use increased ~5%/year with little pollution control (Fig. 1). Aerosol growth slowed in the 1970s with pollution controls in the U.S. and Europe, but accelerated again after ~2000.

The rapid growth of fossil fuel CO2 emissions in the past decade is mainly from increased coal use (Fig. 1), mostly in China with little control of aerosol emissions. It is thus likely that there has been
an increase in the negative (cooling) climate forcing by aerosolsin the past decade, as suggested by regional aerosols measurements in the Far East, but until proper global aerosol monitoring is initiated, as discussed below, the aerosol portion of the amplified Faustian bargain remains largely unquantified.

President Obama's Next Four Years

Lost in the election's afterglow for Democrats and deep funk of Republicans is the hard work to be done and how much the president's success -- which, by definition, is the country's success -- depends on how many of us will have the president's back for the next four years.

President Obama referred to this point in his historic election night speech when he said: "So let us summon a new spirit of patriotism, of responsibility, where each of us resolves to pitch in and work harder and look after not only ourselves, but each other."

He then added: "The role of citizen in our democracy does not end with your vote. America's never been about what can be done for us.  It's about what can be done by us, together."

This is the message every American needs to consider, to face the truth that, prior to the election -- over the last four years -- citizens, democrats included, didn't always have this president's back. There are reasons. The recession, people trying to survive. Ideology. Misinformation. Disagreement. There was also a strange abdication, the sense by some who voted for him that now he can make change.

It doesn't work that way.
