The Hon Kevin Rudd, MP
Prime Minister of Australia
Canberra, Australian Capital Territory, 2600
Dear Prime Minister,
Your leadership is needed on a matter concerning coal-fired power plants and carbon dioxide emission rates in your country, a matter with ramifications for life on our planet, including all species. Prospects for today's children, and especially the world's poor, hinge upon our success in stabilising climate.
For the sake of identification, I am a United States citizen, director of the NASA Goddard Institute for Space Studies and Adjunct Professor at the Columbia University Earth Institute. I am a member of our National Academy of Sciences, have testified before our Senate and House of Representatives on many occasions, have advised our Vice President and Cabinet members on climate change and its relation to energy requirements, and have received numerous awards including the World Wildlife Fund's Duke of Edinburgh Conservation Medal from Prince Philip.
I write, however, as a private citizen, a resident of Kintnersville, Pennsylvania, USA. I was assisted in composing this letter by colleagues, including Australians, Americans, and Europeans, who commented upon a draft letter. Because of the urgency of the matter, I have not collected signatures, but your advisors will verify the authenticity of the science discussion.
I recognise that for years you have been a strong supporter of aggressive forward-looking actions to mitigate dangerous climate change. Also, since your election as Prime Minister of Australia, your government has been active in pressing the international community to take appropriate actions. We are now at a point that bold leadership is needed, leadership that could change the course of human history.
I have read and commend the Interim Report of Professor Ross Garnaut, submitted to your government. The conclusion that net carbon emissions must be cut to a fraction of current emissions must be stunning and sobering to policy-makers. Yet the science is unambiguous: if we burn most of the fossil fuels, releasing the CO2 to the air, we will assuredly destroy much of the fabric of life on the planet. Achievement of required near-zero net emissions by mid-century implies a track with substantial cuts of emissions by 2020. Aggressive near-term fostering of energy efficiency and climate friendly technologies is an imperative for mitigation of the looming climate crisis and optimisation of the economic pathway to the eventual clean-energy world.
Global climate is near critical tipping points that could lead to loss of all summer sea ice in the Arctic with detrimental effects on wildlife, initiation of ice sheet disintegration in West Antarctica and Greenland with progressive, unstoppable global sea level rise, shifting of climatic zones with extermination of many animal and plant species, reduction of freshwater supplies for hundreds of millions of people, and a more intense hydrologic cycle with stronger droughts and forest fires, but also heavier rains and floods, and stronger storms driven by latent heat, including tropical storms, tornados and thunderstorms.
Feasible actions now could still point the world onto a course that minimises climate change. Coal clearly emerges as central to the climate problem from the facts summarised in the attached Fossil Fuel Facts. [See note below] Coal caused fully half of the fossil fuel increase of carbon dioxide (CO2) in the air today, and on the long run coal has the potential to be an even greater source of CO2. Due to the dominant role of coal, solution to global warming must include phase-out of coal except for uses where the CO2 is captured and sequestered. Failing that, we cannot avoid large climate change, because a substantial fraction of the emitted CO2 will stay in the air more than 1000 years.
Yet there are plans for continuing mining of coal, export of coal, and construction of new coal-fired power plants around the world, including in Australia, plants that would have a lifetime of half a century or more. Your leadership in halting these plans could seed a transition that is needed to solve the global warming problem.
Choices among alternative energy sources - renewable energies, energy efficiency, nuclear power, fossil fuels with carbon capture - these are local matters. But decision to phase out coal use unless the CO2 is captured is a global imperative, if we are to preserve the wonders of nature, our coastlines, and our social and economic well being.
Although coal is the dominant issue, there are many important subsidiary ramifications, including the need for rapid transition from oil-fired energy utilities, industrial facilities and transport systems, to clean (solar, hydrogen, gas, wind, geothermal, hot rocks, tide) energy sources, as well as removal of barriers to increased energy efficiency.
