Summary: This study analyzed the historical spatiotemporal changes of compound drought and heatwaves (CDHWs) in Australia and explored the influence of co-occurring El Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) on their frequency and severity. The results showed a significant increase in the frequency, duration, amplitude, and severity of CDHWs in recent years, particularly in eastern Australia. It was also found that the frequency, duration, and severity of CDHWs are significantly increased during strong El Nino phases and moderate-strong positive IOD events, with widespread impacts on northeast and southeast Australia.

Summary: An extreme drought occurred in South China from October 2020 to March 2021, and this study demonstrates that it was closely related to the combined effects of an exceptionally warm northwest Pacific and a moderate La Nina. The sea surface temperature anomaly in these regions resulted in a steeper geopotential height gradient over South China, causing anomalous northeasterly winds and altering water vapor transport and moisture convergence. The study emphasizes the importance of the sea surface temperature variation in the northwest Pacific for the occurrence of the extreme drought.

Summary: Australia experiences four consecutive periods of seesaw wetting and drying between eastern and western regions in the past five decades, lasting for approximately 11 years each. This phenomenon is characterized by gaining water in eastern Australia while losing water in western Australia, and vice versa. The seesaw pattern is related to the strong La Nina event and has implications for future water resource and disaster risk management in Australia.

Summary: This study focuses on the utilitarian and symbolic significance of koalas for Aboriginal communities in Queensland by examining historical records and publications. It highlights the importance of considering regional variations and consulting with Aboriginal communities when planning conservation measures related to koalas.

Summary: The study demonstrates a relationship between long-term rainfall trends, tree canopy decline, and effects on avifauna population dynamics in the Dryandra Woodlands. Changes in Projected Foliage Cover are related to the number of yellow-plumed honeyeaters, while there is a significant difference in apparent survival rates between the two focal species.

Summary: The study reveals weaker IASM activity and dryer climate conditions between 35 and 25 thousand years ago, with grass-dominated savanna. From 25 thousand years ago, increasing moisture and variability in IASM activity were observed. Significant changes occurred around 10 thousand years ago when the continental shelf flooded, leading to the establishment of a quasi-permanent wetland.

Summary: Runnelling, a form of open marsh water management, was developed in Australia in the 1980s and integrated into mosquito control programs in the 1990s. A recent assessment of 47 runnelled saltmarsh sites showed that about half continue to contribute to mosquito control efficacy, with the other half not. Effective maintenance and hydrologic function are crucial factors influencing the efficacy of runnels.

Summary: Vegetation structure in Australia and other regions plays a significant role in global terrestrial carbon sequestration. However, the debate over whether soil carbon in these regions is a net carbon source or sink creates uncertainties for long-term carbon storage. This study examines the relationship between catchment erosion, vegetation composition, carbon cycling, wetland response, and lake carbon accumulation in southeastern Australia over glacial-interglacial timescales. The results suggest that warmer and wetter climate conditions promote increased terrestrial carbon sequestration in temperate Australian landscapes.

Summary: A study on the stratigraphy and chronology of Williams Point at the southern margin of Lake Eyre in Australia reveals revised ages for the lacustrine facies and provides evidence of the lake entering a playa phase. The study also identifies a reliable paleolake level indicator and suggests the extinction of the Genyornis newtoni occurred during a time of hydrological transformation. These findings offer new perspectives on the Quaternary history of Australia's arid zone.

Summary: Kati Thanda-Lake Eyre is the largest global dust hotspot in the Southern Hemisphere, with satellite mapping showing that dust from the region is transported widely across the Tasman Sea, South Pacific Ocean, Southern Ocean, Pilbara/Kimberly, and Indian Ocean. While dust emissions from the southern section of the lake are minimal today, evidence from palaeo-aeolian sediments suggests major dust deflation episodes occurred during the last glacial cycle. Estimations suggest that Kati Thanda-Lake Eyre generated a significant portion of Australia's dust load over the past 80 to 40 thousand years. Despite 80 years of research, there is still much to learn about the climate-landscape interactions and dust generation in the arid heart of Australia.

Summary: This study examines recent shorelines associated with episodic filling events of modern ephemeral playa lakes. The results suggest that lithology and variations in wave energies are major controls on large-scale shoreline geomorphology. The presence or absence of shoreline features is an incomplete indicator of past lake levels, and wave-built landforms in ephemeral playa lake settings need to be considered threshold-related phenomena.
