Hansen Supports Fossil Fuel Tax

UN on wrong track with plans to limit global warming to 2C, says top scientist

Climate change scientist James Hansen says current ‘half arsed’ plans to reduce emissions will lead to dangerous climate change and calls for an honest carbon price to cut fossil fuel use

One of the world’s leading atmospheric scientists has told the UN that its present attempt to limit emissions is “half-arsed and half-baked” and risks handing the next generation a climate system that is out of their control.

James Hansen, former head of Nasa’s Goddard Center and the man who raised awareness of climate change in a key Senate hearing back in 1988 said that the UN meeting was on the wrong track by seeking a 2C maximum rise in temperatures.

“What I am hearing is that the heads of state are planning to clap each other on the back and say this is a very successful conference. If that is what happens, we are screwing the next generation, because we are doing the same as before.

“[A rise of ] 2C is definitely dangerous. We are at the point now where temperatures are hitting the 1C mark and are are on a path above 1C. Even if we reduce emissions 6% a year we will still get 1C.

“Instead we hear the same old thing as Kyoto [in 1997]. We are asking each country to cap emissions, or reduce emissions. In science when you do a well conducted experiment you expect to get the same result. So why are we talking about doing the same again? This is half-arsed and half-baked.”


Hansen, who was speaking at a climate summit for the first time, said the planet was out of energy balance. “There is more warming in the pipeline that will take us into real danger. We are on the edge of handing our children a climate system that is out of control, and that could mean losing half our coastal cities.”

The scientist said that it was historical emissions that were to blame for heating the planet to its current point. “For that the US is responsible for 25%, and the EU about 25%, China only 10%. Per capita, the UK, US and Germany are by far the most responsible. China [per capita] is by an order of magnitude smaller,” he said. 

Hansen said the solution was to get two or three large countries to impose anescalating price on carbon. “The problem is fossil fuels are cheap and as long as they remain so they will be burned. They do not include the effects of warming and air pollution on human health.

“Studies show that if you added $10 a tonne to the price you would reduce [fossil fuel] energy use by 20% in 10 years, and 50% in 20 years. This is the only viable international approach. You cannot ask 190 countries to individually limit their emissions. The price of fossil fuels must be honest. That just needs a few of the major players. It would rapidly move us off fossil fuels.

“It’s not too complicated. It’s not that the problem cannot be solved but that it is not being solved. We need an honest, simple rising carbon fee.”
