A comment on Australia's stance in the world on ABC News 24, 29 Nov 2018
Malte_ABC_Nov2018smaller2.jpg Watch the interview on Australia's stance in a world that struggles to meet its Paris Agreement commitments, let alone 1.5C or 2C. A number of opportunities are missed at the moment within the policy vacuum in Australia. The interview happened on the day of the release of the UNEP 2018 Emission Gap Report, available here: https://www.unenvironment.org/resources/...
Our recent study on Paris Agreement featured in global media
Our recent study in Nature Communications ( https://www.nature.com/articles/s41467-018-07223-9 ) by our PhD researcher Yann Rubiou du Pont and College Director Malte Meinshausen was recently featured in media around the world. For example, see the UK's Independent article below (taken from: https://www.independent.co.uk/environment/climate-change-temperature-paris-agreement-environment-china-...
Keeping under 1.5°C: are we doing enough to avoid dangerous climate change?
Have we missed the opportunity to avoid dangerous climate change? Australia has already experienced over 1 degree of warming with an increase in extreme heat events and severe bushfire weather. What actions need to be taken to get on track to avoid a greater than 1.5°C future? If we don't act, what could our future climate look like? To coincide with the launch of the IPCC Special Report Global...
Power system stability with Kate Summers
The stability of the electricity network are front and centre of the political debate in Australia. Watch our seminar on power system control with Engineer Kate Summers from Pacific Hydro. In a fascinating seminar, held in the College on 15th August 2018, she explains why the big gas and coal (synchronous) generators often get it wrong these days to stabilise frequency across the National...

We are happy to announce that the Energy Transition Hub web presence www.energy-transition-hub.org . Watch that space as we integrate a rich set of resources to that site, such as our new initiatives opennem.org...
New AEMO gas projections out: Our report passes the test of time.
Passing the test of time... Just in case you missed it. AEMO put out their new gas demand and supply projections, called " 2018 Gas Statement of opportunities ", also reported in today's Australian. Remember the times that our last year's report " A short lived gas shortfall " by Tim Forcey and Dylan McConnell created a bit of a stir? Well, feels good to largely pass the test of time as our last...
Recent Australian droughts may be the worst in 800 years
From: https://theconversation.com/recent-australian-droughts-may-be-the-worst-in-800-years-94292 featuring our PhD researcher Mandy Freund and colleague Benjamin Henley Australia is a continent defined by extremes, and recent decades have seen some extraordinary climate events. But droughts, floods, heatwaves, and fires have battered Australia for millennia. Are recent extreme events really worse...

With multiple tools, we intend to support the national energy debate with facts. Follow the supply and demand in the Australian Electricity Market with opennem.org.au - which is a growing platform to promote open data to a wide range of stakeholders. An early product of our Energy Transition Hub, with support from the Energy Consumers Australia. A project by our Dylan McConnell, Simon Holmes à...
Land-based negative emissions: risks for climate mitigation and impacts on sustainable development
Authors : Kate Dooley and Sivan Kartha Abstract : This paper focuses on the risks associated with ‘‘negative emissions’’ technologies (NETs) for drawing carbon dioxide from the atmosphere through photosynthesis and storing it in land-based sinks or underground. Modelled mitigation pathways for 1.5 °C assume NETs that range as high as 1000 Gt CO2. We argue that this is two to three times greater...
An input-output based net-energy assessment of an electricity supply industry
Author : Graham Palmer Abstract : Electricity systems process and upgrade crude feedstock energy from the natural environment using high quality energy inputs, including diesel and electricity. The ratio of electricity output to the energy inputs is termed the energy-return-on-investment (EROI) and may be an important metric linking energy consumption and standard of living. Environmentally...
Geoengineering governance-by-default: an earth system governance perspective
Authors: Anita Talberg , Peter Christoff, Sebastian Thomas, and David Karoly Abstract: Geoengineering—the deliberate interference in the climate system to affect global warming—could have signiﬁcant global environmental and social implications. How to shape formal geoengineering governance mechanisms is an issue of debate. This paper describes and analyses the geoengineering governance landscape...

Historical greenhouse gas concentrations for climate modelling (CMIP6)
Authors : Malte Meinshausen , Elisabeth Vogel , Alexander Nauels , and others. Abstract : Atmospheric greenhouse gas (GHG) concentrations are at unprecedented, record-high levels compared to the last 800 000 years. Those elevated GHG concentrations warm the planet and – partially offset by net cooling effects by aerosols – are largely responsible for the observed warming over the past 150 years...
The risk of migratory methane emissions resulting from the development of Queensland coal seam gas
Authors : Dimitri Lafleur and Mike Sandiford Summary : In sedimentary basins migration of methane and other fluids occurs naturally in response to multiple factors. Natural methane surface seeps are well known in many gas provinces. The pathways for such seeps can be enhanced and new pathways created through subsurface resource developments, leading to so-called induced migratory emissions...
A Framework for Incorporating EROI into Electrical Storage
Author : Graham Palmer Citation : Palmer, G. 2017. Biophysical Economics and Resource Quality 2(6) doi:10.1007/s41247-017-0022-3 Abstract : The contribution from variable renewable energy (VRE) to electricity generation is projected to increase. At low penetration, intermittency can usually be accommodated at low cost. High-penetration VRE will displace conventional generation, and require...
