An open letter to the Prime Minister on the climate crisis, from 154 scientists

Dear The Hon. Malcolm Turnbull MP, Prime Minister of Australia,

The following is an open letter signed by 154 Australian atmospheric, marine, environmental, biological and medical scientists, including several leading climatologists, for your and your government’s attention.

There is no Planet B

In July 2016, global temperatures soared to the hottest in the 136 years of the instrumental record, 0.1℃ warmer than previous warm Julys in 2015, 2011 and 2009. It followed a succession of rising temperatures, moving from 0.42℃ above average in 2000, to 0.87℃ above average by 2015.

Developments in the atmosphere-ocean system reported by major climate research organisations (including NASA, the US National Oceanic and Atmospheric Administration, the US National Snow & Ice Data Center, the UK Met Office Hadley Centre, the Tyndall Centre, the Potsdam Institute; the science academics of dozens of nations; and in Australia the CSIRO and Bureau of Meteorology) include:

We are concerned that global warming, amplified by feedbacks from polar ice melt, methane release from permafrost, and extensive fires, may become irreversible, including the possible collapse of the Atlantic Meridional Overturning Circulation, a crucial component of the global climate system that transfers heat from the tropics to the North Atlantic.

According to James Hansen, NASA’s former chief climate scientist, “burning all fossil fuels would create a different planet than the one that humanity knows”. Joachim Schellnhuber, Germany’s chief climate scientist, has summed up the situation by saying: “We’re simply talking about the very life support system of this planet.”

We note your broad agreement with this point, in light of your 2010 statement that:

…we are as humans conducting a massive science experiment with this planet. It’s the only planet we have got… We know that the consequences of unchecked global warming would be catastrophic… We as a human species have a deep and abiding obligation to this planet and to the generations that will come after us.

While the Paris Agreement remains unbinding and global warming has received minimal attention in the recent elections, governments worldwide are presiding over a large-scale demise of the planetary ecosystems, which threatens to leave large parts of Earth uninhabitable.

We call on the Australian government to tackle the root causes of an unfolding climate tragedy and do what is required to protect future generations and nature, including meaningful reductions of Australia’s peak carbon emissions and coal exports, while there is still time.

There is no Planet B.
