The SMH has an article on the latest round of climate negotiations - It's the end of the world as we know it.
THE world is on track to see "an unrecognisable planet" that is between 4 and 6 degrees hotter by the end of this century, according to new data on greenhouse gas emissions.
As United Nations climate negotiations enter their second week in Doha, Qatar, an Australian-based international research effort that tracks greenhouse gas output will release its annual findings on Monday, showing emissions climbing too quickly to stave off the effects of dangerous climate change.
The new forecast does not include recent revelations about the effects of thawing permafrost, which is starting to release large amounts of methane from the Arctic. This process makes cutting human emissions of fossil fuels even more urgent, scientists say.
The new data from the Global Carbon Project found greenhouse gas emissions are expected to have risen 2.6 per cent by the end of this year, on top of a 3 per cent rise in 2011. Since 1990, the reference year for the Kyoto Protocol, emissions have increased 54 per cent.
It means that the goal of the Doha talks – to hold global temperature rise to 2 degrees – is almost out of reach. That goal requires that emissions peak now and start falling significantly within eight years.
"Unless we change current emissions trends, this year is set to reach 36 billion tonnes of carbon dioxide from the combustion of fossil fuels, we are on the way to an unrecognisable planet of 4 to 6 degrees warmer by the end of this century," said the executive director of the Global Carbon Project, Dr Pep Canadell.
"Unless the negotiators in Doha wake up tomorrow and embrace a new green industrial revolution to rapidly change our energy systems, chances to stay below global warming of 2 degrees Celsius are vanishing very fast, if they are not already gone."
Emissions are growing in line with the most extreme climate models used by the Intergovernmental Panel on Climate Change, according to a paper in the journal Nature Climate Change that explains the Global Carbon Project's findings.
The trajectory means a temperature range of between 3.5 and 6.2 degrees by the year 2100, with a "most likely" range of between 4.2 and 5 degrees. ...
Matthew England, a colleague of Professor Pitman and fellow author of Intergovernmental Panel on Climate Change reports, said: "While the science is clear that emissions reductions are required urgently, each year we are emitting more and more greenhouse gases into the atmosphere. This is like a smoker ramping up the number of cigarettes smoked each day despite grave warnings to stop smoking altogether – sooner or later this catches up with you."
