Climate vulnerability monitor
DARA, 2012The Climate Vulnerability Monitor 2nd Edition reveals that climate change has already held back global development and inaction is a leading global cause of death. Harm is most acute for poor and vulnerable groups but no country is spared either the costs of inaction or the benefits of an alternative path.
Commissioned by the world’s most vulnerable countries and backed by high-level and technical panels, the new Monitor estimates human and economic impacts of climate change and the carbon economy for 184 countries in 2010 and 2030, across 34 indicators.

CAWCR technical report, 43. Exploring the co-benefit of electric vehicle uptake and ozone pollution reduction in Sydney - Final report.
Given the likely pace of change in the electric vehicle market, it is important that the environmental externalities are identified and quantified. In this report we present the results of a modelling study which investigated how ozone pollution in the Greater Metropolitan Region of Sydney NSW, Australia would respond to the replacement of Sydney’s internal combustion engine (ICE) passenger vehicle fleet with a fleet of electric vehicles. A brief description of the modelling methodology is provided in the next section, and a summary of the modelling outcomes is provided in the following sectio ...
CAWCR technical report, 45. Evaluation of the TIGER SuperDARN Over-The-Horizon radar systems for providing remotely sensed marine and oceanographic data over the Southern Ocean
Greenwood Robert; Schuiz Eric; Parkinson Murray; et al. - Centre for Australian Weather and Climate Research, 2011The Tasman International Geospace Environment Radar systems (TIGER) located in Tasmania and New Zealand are High Frequency (HF) Over-The-Horizon Radar (OTHR) systems and represent Australia’s contribution to the Super Dual Auroral Radar Network (SuperDARN). SuperDARN is a network of more than 20 HF radars located at mid-high latitudes with fields of view covering the polar regions for the study of ionospheric physics. The TIGER systems have overlapping fields of view that cover much of the Southern Ocean in the Australian sector. The development and operation of TIGER has been led by La Trobe ...
CAWCR technical report, 44. Composition of the atmosphere - abstracts of the fifth CAWCR Workshop 15 November - 17 November 2011, Melbourne, Australia
The aims of the meeting are to: 1) understand the role of atmospheric chemistry and composition in global atmospheric change as expressed in the Australasian region and internationally; and 2) to provide a forum for atmospheric composition researchers from different disciplines (in-situ observations, remote sensing observations, modelling) to share ideas, enhance collaboration and develop a coordinated regional approach to characterising atmospheric processes in Australasia.
CAWCR technical report, 42. Global climate goals for temperature, concentrations, emissions and cumulative emissions
Raupach Mickael R.; Harman Ian N.; Canadell Josep G. - Centre for Australian Weather and Climate Research, 2011There are many different ways of quantifying the broad goal of "avoidance of dangerous human interference with the climate system", including targets for global temperature rise, radiative forcing, greenhouse gas (GHG) concentrations, GHG emissions in particular years, and cumulative GHG emissions ("carbon budgets"). The purpose of this report is to provide relationships between these different statements of a climate goal. Broadly, the approach is to start from target for global temperature increase above preindustrial temperatures (such as two degrees Celsius or any other target, to be met w ...
CAWCR technical report, 40. Comparison of techniques for the calibration of coupled model forecasts of Murray Darling Basin seasonal mean rainfall
Charles Andrew; Hendon Harry H.; Wang Q.J.; et al. - Centre for Australian Weather and Climate Research, 2011Ensemble forecasts of South Eastern Australian rainfall from POAMA 1.5, a coupled oceanatmosphere dynamical model based seasonal prediction system run experimentally at the Bureau of Meteorology, tend to be under dispersed leading to overconfident probability forecasts. The poor reliability of seasonal forecasts based on dynamical coupled models is a barrier to their adoption as official outlooks by the Bureau of Meteorology. One approach to correcting this problem is model calibration, in which the probability distribution produced by the model is adjusted in light of available information ab ...
CAWCR technical report, 39. Assessment of international seasonal rainfall forecasts for Australia and the benefit of multi-model ensembles for improving reliability
In this report we assess forecasts from Predictive Ocean Atmosphere Model for Australia (POAMA) in comparison to international dynamical coupled model forecast systems, which are archived as part of the ENSEMBLES project. We investigate how universal the lack of reliability is in dynamical forecasts of regional rainfall, in order to highlight any potential for improvement of the POAMA system. The systems assessed in this report show that overconfidence and lack of reliability for regional rainfall forecasts is a common problem. Due to the clear need for improved reliability and more accurate s ...
CAWCR technical report, 37. Large-scale indicators of Australian East Coast lows and associated extreme weather events
Extra-tropical cyclones that develop near the east coast of Australia often have severe consequences such as flash flooding and damaging winds and seas, as well as beneficial consequences such as being responsible for heavy rainfall events that contribute significantly to total rainfall and runoff. There is subjective evidence that the development of most major events, commonly known as East Coast Lows, is associated with the movement of a high amplitude upper-tropospheric trough system over eastern Australia. This report examines a number of large-scale diagnostic quantities in the upper trop ...

Climate: observations, projections and impacts
The Met.Office, 2011Understanding the potential impacts of climate change is essential for informing both adaptation strategies and actions to avoid dangerous levels of climate change.
But assessing the impacts is scientifically challenging and has, until now, been fragmented. To date, only a limited amount of information about past climate change and its future impacts has been available at national level, while approaches to the science itself have varied between countries.
In April 2011, we were asked by the United Kingdom's Secretary of State for Energy and Climate Change to begi ...

CSIRO Climate Adaptation Flagship working paper series, 7. Current and potential applications of typologies in vulnerability assessments and adaptation science
Typologies are a systematic grouping of entities or units of interest based on similarity. Typologies are widely applied in a variety of domains of research and practice including natural resource management, agriculture, health, marketing and development. They are used mainly to reduce complexity in the domain of concern to improve understanding and communication, detect patterns, aid decisions, prioritise and allocate resources, and tailor a variety of activities, strategies and processes. In this paper, we assess the current use of typologies within the realm of climate vulnerability assess ...

Climate Science update : a report to the 2011 Garnaut review
Keenan T.D.; Cleugh H.A. - Centre for Australian Weather and Climate Research, 2010 (CAWCR Technical Report-No. 036)This technical report is based on scientific contributions from both CSIRO1 and the Bureau of Meteorology. It is not intended to be comprehensive in terms of depth or breadth. Rather it is a snapshot of the “state of the science” mainly from the perspective of CAWCR scientific expertise based on peer-reviewed literature. The issues covered relate mainly (but not exclusively) to the scope of Working Group One (WGI) of the Intergovernmental Panel on Climate Change (http://www.ipcc.ch/); i.e. an assessment of the physical and scientific aspects of the climate system and climate change. We are pa ...
Approaches for generating climate change scenarios for use in drought projections : a review
Kirono G.C.; Hennessy Kevin; Mpelasoka Freddie; et al. - Centre for Australian Weather and Climate Research, 2010 (CAWCR Technical Report-No. 034)This report describes approaches used for constructing climate projections from a set of climate model simulations for use in drought projections, particularly in Australia. The description includes the pros and cons of each approach with respect to the calculation process, data that are produced, and discussion of the main sources of uncertainty. Although the main focus is on research and approaches that are applied in Australia, the report also briefly discusses approaches applied elsewhere in the world.
