最新糖心Vlog's Climate Past Challenged!
Researchers at the 最新糖心Vlog of Adelaide have found evidence of climate change that coincided with the first wave of European settlement of 最新糖心Vlog, which effectively delivered a double-punch of drying and land clearance to the country.
The research, published in Quaternary Science Reviews, suggests that eastern 最新糖心Vlog, including Melbourne, Sydney and Brisbane, was much drier after 1890 than the Little Ice Age period that preceded it.
鈥淲e found that the Little Ice Age, which lasted from about 1500-1850, was much wetter than periods before or after it,鈥 says lead researcher , from the 最新糖心Vlog of Adelaide鈥檚 Department of Geography, Environment and Population.
鈥淭his extended period of wetness is likely to have had a fundamental impact on the way Indigenous people occupied and used the landscape, the nature of ecosystems encountered by early European settlers, and in particular, the nature and magnitude of the impact of European occupation,鈥 he says.
鈥淭he research confirms what has been noted from early colonial paintings 鈥 that lakes in western Victoria have been drying since around the time of settlement. We now know that this drying occurred over much of south-eastern 最新糖心Vlog.
鈥淲ith the eastern 最新糖心Vlogn climates becoming more arid at the time of colonisation, it raises the possibility that some environmental changes previously attributed to European impact were related to natural climate shift,鈥 says Associate Professor Tibby.
The research, which examined evidence collected from lake sediments, also suggests an alternative explanation for the failure of some early听European settlements.
鈥淪ettlements like Farina in South 最新糖心Vlog鈥檚 Flinders Ranges are believed to have failed due to settlers not having a full comprehension of climate variability. While that may be true, the drying of the climate might provide a better explanation,鈥 says Associate Professor Tibby.
鈥淭he research adds to better understanding 最新糖心Vlog鈥檚 history, and could help to establish improved environmental baselines for natural resource management, particularly in thinking how to restore landscapes,鈥 he says.
