PhD opportunity: Unravelling the role of lags and legacies in explaining the response of grasslands to elevated CO2

August 30, 2019 10:19 am Published by Comments Off on PhD opportunity: Unravelling the role of lags and legacies in explaining the response of grasslands to elevated CO2

This project will apply a state of the art, hierarchical Bayesian modelling framework to determine how past climatic conditions influence current responses to high CO2concentrations. The project will use data from a new, specially-designed experiment, as well as results from past Free-Air Carbon dioxide Enrichment (FACE) and Open-top chamber (OTC) experiments, to close this knowledge gap.

BoM03: The role of soil moisture drought for wheat production in Australia

July 16, 2019 3:00 am Published by Comments Off on BoM03: The role of soil moisture drought for wheat production in Australia

The aim of this student project is to investigate the relationships between hydrological extremes (especially soil moisture drought) and wheat production in Australia. The outcome of the project may inform the development seasonal forecasts of hydrological indicators for agricultural production in Australia.

El Niño Southern Oscillation (ENSO) risks for Western Australian graziers

Bella Blanche writes about spending time on the vast Macfarlane Station in Tambo, Queensland and introduces a methodology to assess risks posed by climate change, and the vulnerability of the native rangeland resources located west of the Great Dividing Range.

UNSW-CAN2: Climate change and East African rainfall: combining observations from local farmers and weather stations

September 18, 2018 9:59 am Published by Comments Off on UNSW-CAN2: Climate change and East African rainfall: combining observations from local farmers and weather stations

Climate change is affecting weather patterns in many locations. In East Africa, changing rainfall would challenge the livelihoods of farmers. However, perceptions of local farmers and data from local weather stations differ. Is rainfall changing? How can we understand these two important information sources?

Drought RP report – August 2018

Research has now begun in earnest in the Drought Research Program with all key staff finally in place. This has proved timely. At the time of writing (August 2018) most of NSW has been drought declared and forecasters suggesting little sign of drought-breaking rains over coming months.

Research brief: Droughts inconsistently represented across climate models

July 6, 2018 2:18 am Published by Comments Off on Research brief: Droughts inconsistently represented across climate models

This study evaluated GCMs for common drought metrics during the past 55 years. It found different models can produce very different simulations of drought, depending on the type of drought and metric analysed. The study points to a need to improve GCMs for droughts to reduce uncertainties in future projections.

Regional adaptions can cool heat extremes by up to 2-3°C

New research published in Nature Geoscience has found that climate engineering that modifies the properties of the land surface in highly populated areas and agricultural areas over North America, Europe and Asia could reduce extreme temperatures there by up to 2-3°C.
