Recent, unprecedented, climate-driven forest collapses in Western Australia show us that ecosystem change can be sudden, dramatic and catastrophic. These collapses are a clear signal that we must develop…

Elephants in the room, part two For all our schemes and mantras about making our lives environmentally “sustainable”, humanity’s assault on the planet not only continues but expands. What are the deep…
The numbers are just in. At a time when we need to be urgently reducing our CO₂ emissions, we are now emitting more than at any time in human history. However, it’s not too late to turn things around…
It’s not just greenhouse gases that affect climate: other air pollution could be changing atmospheric circulation.

The Earth’s principal climatic zones appear to be shifting poleward. If this continues, as climate models project, the weather patterns that give rise to deserts in the subtropics, and stormy wet weather…
We’re just coming to grips with Interdecadal Pacific Oscillation, one of the many climate modes that cause Australia’s wide and wonderful range of climate variability.

While most people now understand that the enhanced greenhouse effect means a much warmer planet, communicating regional shifts in weather remains a significant challenge. As with most complex science…
We all know moving is hard. It’s even harder when you don’t want to go. But it can still be a positive decision.

Who are the “climate change migrants” we hear about with increasing regularity in the media and in global and regional policy forums? Are they the victims of devastating environmental forces - the result…
The climate system operates with a range of discrete modes.

Scientists’ job is to brief us on how future climate might affect our lives, even when all the data isn’t in.

The days of ‘sit down, shut up and do your science’ are over. Today’s students ask hard questions.
University of Iowa
Two recently published books suggest that the public - and school children in particular - are being fed lies about environmental issues such as climate change. The books - “How to Get Expelled from School…
Rain’s coming: does that mean there’s no such thing as climate change?

A quarter of the extreme precipitation that led to the Queensland floods has been found to have come from a third, until…
Natural records taken from coral, tree rings and ice cores helped to provide a “climate picture” for the past 1,000 years.

One of the benefits of using the health frame is that it makes the issues more tangible – here and now and about people, not just polar bears.

Climate change is a complex problem but appears to many people as lacking immediate impact on their lives. Reconceptualising it as a health issue may allow for both better understanding of the issue and…
Cows’ methane emissions can be measured with lasers, but it’s not that easy to measure emissions from an extinct sauropod.
Mark Witton
Last week my colleagues and I published a paper showing how methane emitted by dinosaurs could have affected the world’s climate. The media response was huge, with 100+ interviews by email and phone, and…
The floods that engulfed Sydney on March 8 this year are expected to become a more common occurrence.

Rising sea levels could threaten up to 60,000 houses, 1200 commercial buildings and 250 kilometres of highway in NSW by the end of the century, a report by the federal government’s Climate Commission says…
Courageous dissent? “The MTC is patting itself on the back for staging The Heretic. But the MTC is not being bold … it is being cowardly.”

Who would have thought the Melbourne Theatre Company would get into bed with Andrew Bolt? The MTC’s new play The Heretic, which premieres on 17 May, tells the story of climate scientist Dr Diane Cassell…
We need to know more about how ice sheets interact with the warming oceans and warming atmosphere.

Satellite and in situ observations show sea level is continuing to rise. In the last Intergovernmental Panel on Climate Change report, earth system model projections indicated global sea-level rise by…
Knocking down forests and planting palm oil makes sense in Asia. Providing alternative income sources for villagers could make it less attractive.
Simon J. Rowntree
Reducing poverty in developing countries through economic development is often contrary to addressing climate change. In countries like Indonesia, many of the strongest drivers of the economy – palm oil…
