Climate Change In Arid Environments: Revisiting The Past To Understand The Future, Elena Lioubimtseva

Peer Reviewed Articles

Arid regions are expected to undergo significant changes under a scenario of climate warming, but there is considerable variability and uncertainty in these estimates between different scenarios. The complexities of precipitation changes, vegetation–climate feedbacks and direct physiological effects of CO2 on vegetation present particular challenges for climate change modelling of arid regions. Great uncertainties exist in the prediction of arid ecosystem responses to elevated CO2 and global warming. Palaeodata provide important information about the past frequency, intensity and subregional patterns of change in the world’s deserts that cannot always be captured by the climatic models. However, it is important to …
