Squaring up to difficult truths: how to reduce the population

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…
China’s emissions keep increasing, but it’s burning less fuel for every increase in GDP. Bert van Dijk

IEA reveals emissions are up again, but it’s not all bad news

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. NASA Goddard Photo and Video

Poleward-shifting climate zones - where are they headed and why?

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. mattharvey1/Flickr

Decade to decade changes in our climate – what’s really going on?

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. United Nations

Environmental migrants: victims, or heroes of adaptation?

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. Patrick Hoesly

Explainer: climate modes and drought

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

Droughts & flooding rains: what is due to climate change?

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…
The days of ‘sit down, shut up and do your science’ are over. Today’s students ask hard questions. University of Iowa

Teaching kids to think critically about climate

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? Georgie Sharp

A land of (more extreme) droughts and flooding rains?

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…

Post-1950s warming in region unmatched in 1,000 years

Update October 2012: The manuscript “Evidence of unusual late 20th century warming from an Australasian temperature reconstruction spanning the last millennium” by Joelle Gergis, Raphael Neukom, Ailie…
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. Roderick Eime/AAP

Reframing climate change could deliver health benefits

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

How do you make a dinosaur burp in a bag? Measuring prehistoric methane

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…

Floods and heatwaves to increase across NSW

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…

Heretic: Melbourne Theatre Company runs with the goons

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. Greenpeace/ADavies

Improving sea-level projections

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

Forestry, economic development & climate change in Asia: resolving the tension
