The impact of climate extreme events on global agricultural yields
Climate extreme events, such as droughts, heat waves, cold spells or heavy precipitation events, pose significant risks to food production and the livelihoods of farmers. Understanding the effect of such events on crop ...
Australian rainfall and El Niño diversity: past variability and context for recent changes
The climate system integrates internally and externally induced variability at various time scales as a result of interactions between the ocean and atmosphere. The influence of external forcing on the climate system and ...
The energy business system: transformation, social innovation & disruptive smart grid business models
A radical shift from a high- to a low-carbon energy system is not occurring at the speed required to address climate change. One reason for this, is that conventional energy firms are locked into producing shareholder ...
Governing geoengineering sustainably: a scenario exercise to inform Australian geoengineering policy development
Geoengineering, the technofix to climate change, is a complex, contentious and high-stakes proposal. Yet in the absence of credible long-term global emissions reduction, the idea cannot be overlooked. To ensure that ...
Cenozoic floral and climate record from brown coals of southeastern Australia
The brown coals of the Latrobe Group, Gippsland Basin, Australia, record an exceptional terrestrial floral and climate record from the Eocene to Miocene. Detailed palynological analysis reveals that the peatland floral ...
Cryogenian iron formations: glaciation and oxygenation
The Cryogenian Period (720–635 Ma) experienced extreme glaciations broadly coincident with a transformation of the Earth’s surface oxidation state, supercontinent breakup, and the evolution of complex animal multicellularity. ...
Early Earth crustal evolution: insights from the mafic rock record of the Pilbara Craton
Archaean greenstone belts are Earth’s oldest known volcanic rock records of an early, less differentiated crust. This study targets the Palaeoarchaean volcanic rock record of the East Pilbara Craton in Western Australia ...
Remote sensing tropical cyclone rainfall over the southwest Pacific region
The south-west Pacific (SWP) region is susceptible to the catastrophic effects of tropical cyclones (TCs). The region, therefore, has received adequate attention in terms of scientific research pertaining to TC genesis, ...
Verification of satellite estimates and NWP model forecasts for tropical cyclone rainfall
This study evaluates the TRMM 3B42 version 7 (V7) estimates of daily rainfall in tropical cyclones (TCs) using the Comprehensive Paciﬁc Rainfall Database (PACRAIN) of 24h rain gauge observations. The evaluation is performed ...
A low-temperature thermochronology investigation of the Turkana Depression: Implications for the development of the East African Rift System
The Turkana Depression is one of the most important segments of the East African Rift System (EARS) for studying the onset of intracontinental rifting and the influence of pre-existing lithospheric heterogeneities on ...
