Predator-prey model deepens understanding of weather

A mathematical formula describing the population dynamics of prey animals such as gazelles and their predators has been adapted…

Climate change, personal experience and the vagaries of memory

We see it in the media all the time. Regular beachgoers who see no evidence for sea-level rise, farmers trusting long-term experience over Bureau of Meteorology forecasting, Antarctic sea-captains whose…
Julia Gillard can sell the tax better if she puts it in terms of the natural wonders we are buying back. AAP

The perception paradox: understanding risk is key to selling the carbon tax

Science is strengthening its view that business-as-usual emissions of greenhouse gases will result in serious risks while the Australian public’s perception of climate change as a risk erodes. A recent…
The rate at which sea levels are rising can change depending on when or where the measurements were taken, scientists say. Flickr/Brentbat

Sea levels continue to rise, but not uniformly: CSIRO

Global average sea levels continue to rise but readings vary greatly depending on when and where they are taken, a leading expert on coastal impacts of climate change has said, warning that selective sea…
Are these the sorts of speakers you go to a university to hear? AAP.

Why academics should steer clear of public debate

The most important issue raised by Lord Monckton’s controversial appearance on two Western Australian campuses is not the limit of free speech or Monckton’s scientific competence. Rather it is whether…

There’s always the sun: solar forcing and climate change

Climate science has now thoroughly outlined the risk associated with increasing greenhouse gases. Significant and rapid warming of the climate system is now expected to occur over the next century and…

Gillard’s carbon tax fightback evens up the playing field

Before the details of the carbon tax were released this week, the government was fighting with one hand tied behind its back. Sometimes it looked like it had both hands and feet manacled as Prime Minister…
The scientists are talking and the Prime Minister is nodding, but is she really listening? AAP

Carbon tax plan is politically astute but profoundly inadequate

Amid the hullabaloo about the carbon tax and Clean Energy Future plan, few seem to spot its critical discrepancy. It recognises that maintaining a safe climate requires stabilising carbon pollution in…
Money is the key theme across the climate change debate: what happened to sustainability? louisa catlover/flickr

A clean energy future should be about more than money

The Government’s equation for creating a prosperous and sustainable Australia includes four key factors: carbon price, renewable energy, energy efficiency and land use efficiency. But it is evident that…
Locking carbon dioxide in soils and crops also stimulates emission of other greenhouse gases like methane and nitrous oxide, a study found, meaning the capacity of land ecosystems to slow climate warming may have been overestimated. Flickr/AndyCarvin

Land carbon offset capacity may have been overestimated

The ability of land ecosystems like crops and soils to slow down climate change may have been overestimated because some of these ‘carbon sinks’ actually emit more greenhouse gases than first thought…
A survey of 140 economists found 60% were in favour of the Gillard government’s carbon tax policy. AAP

Economists back carbon tax package

A survey of 145 economists released today found that 60% believe the Gillard government’s carbon tax is good economic policy. The carbon tax package, announced on Sunday, penalises 500 heavy polluters…

Real climate debates: a report from the IUGG General Assembly

In 2100, will sea level be one metre higher than now, or only 50cm? The Thames Barrage is designed to protect London from flooding by storm surges in up to one in a thousand year events. With 50cm higher…
Prime Minister Julia Gillard and Climate Change Minister Greg Combet address a press conference on Sunday. A carbon tax package announced today includes compensation measures and a radical overhaul of income tax policy. ABC News24

The carbon tax: the experts respond

The Australian government announced on Sunday it would introduce a carbon tax at $23 a tonne next July, rising 2.5% annually plus inflation and moving to a market-based emissions trading scheme in 2015…
She’s got the book, but did she read it? Ross Garnaut explains the advice he gave. AAP

Ross Garnaut discusses the economics behind the carbon tax

Top Conversation author Professor Stephan Lewandowsky and former Western Australian Premier Carmen Lawrence were part of a group that sat down with Ross Garnaut during his recent visit to UWA. During the…
