450 Million year history of plant gas exchange capacity and the role of atmospheric carbon dioxide

我们的星球面临着大气中二氧化碳的增加，这在人类历史上是前所未有的，但在古代就发生过。通过研究过去大气二氧化碳、植物气体交换和气候变化之间的关系，我们将获得对未来大陆碳和水通量情景的强大全球洞察力。这种全球视角对于澳大利亚评估其与其他国家相比对全球气候变化的脆弱性至关重要，从而为国家规划景观资源利用，包括第一产业，水利基础设施和碳交易提供信息。

Our planet faces an increase in atmospheric carbon dioxide that is unprecedented in human history, but has occurred in ancient times. By studying the relationship between past changes in atmospheric carbon dioxide, plant gas exchange and climate we will gain powerful global insight into future scenarios of continental carbon and water fluxes. This global perspective is essential for Australia to assess its vulnerability to global climate change in relation to other nations, thereby informing national planning of landscape resource use, including primary industry, water infrastructure and carbon trading.
