US development of wind energy is lowering emissions without reducing economic growth. Sam Beebe

Climate Commission: global climate action gathers momentum

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. AAP

Shade cloth over reefs? Scientists call for ‘last resort’ measures

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? shannonkringen

Help needed: can you fix the science/ society divide?

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…

Ocean winners and losers revealed in Marine Report Card

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.

On the move: corals migrate south into NSW’s warming waters

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…

What does ‘belief’ in climate change really mean?

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

On global temperatures, Berkeley’s BEST is similar to the rest

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…

Hurrah for Mars, but why not more curiosity about life on Earth?

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…
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…
