As long as the temperature does not rise 2ºC more than average, combining the effects of elevated carbon dioxide and high temperature with water restrictions actually improves biomass and grain yield.
Mr Dias de Oliveira's finding could have significant impact on the future of crop production in the Mediterranean-type climatic wheat-growing regions of Australia, where climate change is expected to have a severe impact on annual yields of 20 million tonnes of wheat over the next 50 years.
…"Our studies unravelled the impact of interaction between elevated CO2, high temperature and water stress in wheat. The vital information generated from the project will help towards developing climate ready wheat for the future," Professor Siddique said. The PhD project is supported by UWA, CSIRO and Department of Agriculture, Forestry and Fisheries (DAFF)….

this is hardly a groundbreaking study and hardly a 'first'. it is well known that soil moisture increases under elevated CO2 by allowing more stomatal closure, especially in contained studies like this one using low tunnels.
also can you please start linking to the actual papers, so we can evaluate them ourselves without a whole lot of time to find them?
