Ninety countries representing 90% of the global economy are committed to reducing their greenhouse emissions and are taking action to do so. This is one of the take-home messages from the Climate Commission’s…
Scientists have suggested using shade cloth to protect corals from the heat stress that leads to coral bleaching.

Unconventional tactics, including using shade cloth to protect corals from heat stress, must form part of future ocean management and conservation plans, argues a scientist from the University of Queensland…
Could listening be the way forward for scientists and science?

Want to help fix the science/ society divide? We’re making a documentary looking at how we might do this, and we’re looking for your help. Why? Well … You don’t need to be a rocket sociologist to know…
The news treats nature as a backdrop to the dramas and delights of human life. In the 21st century, our dramas are driving nature’s destruction, and that destruction threatens an end to our delights. But…
Little penguins are among a number of species that are threatened by climate change.

Fish are on the move in Australia’s waters. In southern Australia, scientists, commercial and recreational fishers, divers and beach-goers are reporting the presence of new species. The movement of species…
Coral species Acropora monticulosa is becoming more abundant at the Solitary Islands in northern NSW.
The east coast of Australia is a global hotspot for the effects of climate change, especially in the marine realm, where average water temperatures have increased by almost half a degree over the last…
Many Australians think they have experienced events associated with climate change.

Where one stands on “climate change” has been such a vexed and often confusing issue, at dinner parties, over coffee, with the taxi driver, and in terms of media reporting of where the Australian public…
Global land-surface temperatures are up, but it’s not really news.
Stuart Dowell
The Berkeley Earth Surface Temperature (BEST) study recently found that global land-surface temperatures have increased by about 1°C since the 1950s — and 1.5°C since the mid-18th century. These results…
We know next to nothing about Earth ecology.

The landing of the explorer Curiosity on Mars is a fantastic affirmation of the extraordinary technical capacities of humans. A series of remote, high risk choreographed moves saw a small mobile laboratory…
Significant changes to New Zealand’s environment and climate did not affect the population size of the now extinct moa. Researchers…
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.

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.

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…
Relax and have a drink, old chap; the planet has managed to look after itself so far without any fuss.

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…
The sun rises on another smoggy day in China, which is now responsible for a quarter of the world’s greenhouse gas emissions.

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…
Sign of things to come: a depleted Lake Hume in 2007, when the big dry still had a couple years to run.

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.

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.

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…
