Australians generally accept that the climate is changing, but we have lost confidence in politicians, experts, and the media to guide us in what to do about it. Flickr/spodzone

Reading the Climate of the Nation 2012

Over the past several decades, scientists have studied the climate of the world and how that is changing. These studies have built on the recognition, made over 150 years ago by John Tindall, that certain…
Tree rings from around the time of Christ suggest warmer regional temperatures than those between the 1950s to the 1980s, but this does not imply higher mean global temperatures. Flickr/Petrified Forest Ranger

On tree rings, CO2 levels and the Pliocene

A study of tree-ring data recently found that in some regions temperatures during Roman times (21AD to 50AD) were 1.05 degrees Celsius higher than the 1951-1980 mean. The paper’s lead author, Professor…

Climate change and the soothing message of luke-warmism

We are familiar with the tactics, arguments, and personnel of the denial industry. Yet there is a perhaps more insidious and influential line of argument that is preventing the world from responding to…

Rich nations should do more on climate, say Chinese

Greenhouse gas cuts pledged by developed countries will not be enough to stop temperatures rising by 2 degrees by 2100, according to Chinese researchers who argue wealthy nations should bear greater responsibility…

Climate change and Victoria: high time to innovate, adapt, and cope

Victoria has entered a critical decade in the race to adapt for the stresses of climate change, according to a new report from the Climate Commission. Following the release of Victorian climate impacts…
Economic modelling shows Australia’s GDP will be modestly affected by the carbon tax in the long term: but the equitable redistribution of tax revenue will be critical. AAP

The carbon tax: insurance against climate change?

Cutting greenhouse gas emissions is like buying an insurance policy: we incur a cost to reduce a risk. Every year Australians spend millions on insuring homes, cars and their health, not because they know…
Landcare get-together: reducing our toll on nature comes in part from many of us taking steps that individually are not always so big, but which accumulate. The carbon tax is one such step. Flickr/feral arts

Little by little: the benefits of Australian climate policy

A catchment threatened by salinity can’t be repaired by one or two landholders. Revegetation designed to lower watertables has its greatest ecological benefit where the plants are, but its net impact on…
Former politician and economist John Hewson speaks to ANU’s Crawford School’s Bruce Chapman and Daniel Connell.

John Hewson: tax reform doesn’t just mean lowering taxes

Welcome to the latest in our In Conversation series, between former politician and economist Dr John Hewson, Australian National University (ANU) Crawford School Director of Policy Impact Professor Bruce…

2011 to be remembered as the year of extreme weather

Severe droughts, floods and landslides devastated parts of the world last year as carbon dioxide concentrations climbed to the highest levels in recorded history, according to a global report on climate…
What does it matter how much rain falls on the ocean? For understanding climate, it matters quite a lot. Ines Hegedus-Garcia

Are the world’s wet regions becoming wetter and dry regions becoming drier?

Surprising evidence from the oceans suggests they are responding to warming at a faster rate than we previously thought. These changes are expressed by patterns of freshening and enhanced salinity in the…
Climate change is only one of many pressures farmers will have to adapt to. Pete Hill

The three Ps of climate change and agriculture

Opinions on anthropogenic climate change vary greatly across society, and it appears that Australia’s farmers remain largely sceptical about the causes of climate change. Recent surveys show that only…

Climate change linked to narrowing leaves

Climate change is causing the leaves of at least one subspecies of Australian plant to narrow in size, a team from the University of Adelaide has found. Their study shows that the leaves of the Narrow-leaf…
Tony Abbott has pledged to repeal the carbon tax, but it may be more difficult than he thinks. AAP/David Crosling

Tony Abbott cannot escape the international climate game

What’s in a name? Well, like “Montague” and “Capulet” in Shakespeare’s play, names matter quite a lot in the tribal world of Australian climate politics. The notion of a “carbon tax” has struck a raw nerve…
This is carbon. The carbon you keep hearing about on the news is probably carbon dioxide. It doesn’t look like this. Rui Costa

What is ‘carbon pollution’ and why are we trying to stop it?

You’ll doubtless have heard Australia is introducing a “carbon tax” this Sunday to reduce “carbon pollution”. What is being controlled is not just any carbon but emissions of a specific gas, carbon dioxide…

Building the new economy: alternative strategies for the 99%

Bob Massie, CEO of the New Economics Institute opened the recent Strategies for a New Economy conference, held at Bard College, New York with a thoughtful response to the criticism that the Occupy movement…
