Climate Change: Why We Can't Wait
By James Hansen, The Nation. Posted April 21, 2007.
The country's leading climatologist gives us the five necessary steps we need to take to prevent catastrophic climate change.This is an adaptation of a talk delivered February 26 at the National Press Club. Comments relating to policy are Dr. Hansen's personal opinion and do not represent a NASA position.
There's a huge gap between what is understood about global warming by the relevant scientific community and what is known about global warming by those who need to know: the public and policy-makers. We've had, in the past thirty years, one degree Fahrenheit of global warming.
But there's another one degree Fahrenheit in the pipeline due to gases that are already in the atmosphere. And there's another one degree Fahrenheit in the pipeline because of the energy infrastructure now in place -- for example, power plants and vehicles that we're not going to take off the road even if we decide that we're going to address this problem.
The Energy Department says that we're going to continue to put more and more CO2 in the atmosphere each year -- not just additional CO2 but more than we put in the year before.
If we do follow that path, even for another ten years, it guarantees that we will have dramatic climate changes that produce what I would call a different planet -- one without sea ice in the Arctic; with worldwide, repeated coastal tragedies associated with storms and a continuously rising sea level; and with regional disruptions due to freshwater shortages and shifting climatic zones.

These problems are worse now than I've seen in my thirty years in government. But they're not new. I don't know anything in our Constitution that says that the executive branch should filter scientific information going to Congressional committees. Reform of communication practices is needed if our government is to function the way our Founders intended it to work.
The global warming problem has brought into focus an overall problem: the pervasive influence of special interests on the functioning of our government and on communications with the public. It seems to me that it will be difficult to solve the global warming problem until we have effective campaign finance reform, so that special interests no longer have such a big influence on policy-makers. .......
