Research brief: How predictable are land-atmosphere fluxes in different ecosystems?
A new study by CLEX researchers using observations from FLUXNET sites identifies regions of high and low predictability and will likely help improve land surface model evaluation.

Research brief: Some trees may survive future heat better than expected
This research suggests some trees and in particular, Australian trees, may be more resilient than expected to future warming and extreme events. These findings have implications for planning around which species to plant in “green cities” to help mitigate future climate extremes.

Climate change to worsen Eastern Australia’s winter pollution
Asthmatics and those affected by polluted environments living around major cities along Australia’s east coast could find life much harder over the next 50 years as stronger inversion layers caused by climate change trap more pollution.

Research brief: Marine heatwaves increase around Tasmania
Centre of Excellence researchers have identified 12 marine heatwave types off the east coast of Tasmania, a location recognised as a global warming hotspot. Here the average sea surface temperatures here have been rising at four times the global average and trends in marine heatwaves are showing significant increases in number.

Hotter, longer, more frequent – marine heatwaves on the rise
An international study in Nature Communications co-authored by researchers from the ARC Centre of Excellence for Climate Extremes (CLEX) and the Institute of Marine and Antarctic Studies (IMAS) reveals globally marine heatwaves have increased over the past century in number, length and intensity as a direct result of warming oceans.

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.

Research brief: More than photosynthesis reduced when plants under stress
The reduction in growth of plants restricted by limitations on nutrients, temperature and/or water stress, didn’t just reduce photosynthesis but led to negative feedbacks in plant carbon balance processes.

Research brief: Mapping transpiration in climate models
When researchers compared the results derived from FLUXNET data with the results synthesised from the literature, they found substantial differences. As a result, they suggest a new benchmarking metric that could be used to test existing hypotheses embedded in climate models and have mapped a path forward involving using further detailed observations to improve the…

Research brief: Understanding water-use efficiency in plants
This study explored the key sources of uncertainty when scaling leaf-level understanding of water-use efficiency to ecosystem scales. The results provide key insights into interpreting (ecosystem-scale) eddy-covariance derived water-use efficiency in an ecophysiological context.

Research brief: New evapotranspiration product
This paper combines existing global evapotranspiration estimates to create a new global product with an observationally constrained estimate of uncertainty. It utilises the latest release of ground-based estimates to show that even point-based evapotranspiration estimates have information about much larger spatial scales.
