The
computer modeling they used in their study was able to identify when and where oxygen levels would likely reach historic lows that could not be recovered from, by simulating natural ocean processes and showing broad - scale patterns across the globe.
«Factors affecting extinction and origination of species are surprisingly different, with past climate change having the highest impact on extinction but not on originations,» notes researcher Daniele Silvestro from the GGBC who developed the
mathematical model used in the study.
The
numerical model used in this study calculated sulfate reduction, methane production, and a broad array of other biogeochemical cycles in the ocean for the billion years between 1.8 billion and 800 million years ago.
Jacobson said he agreed that «models need to be continuously tested,» and noted that
the model he used in this study is one he's been refining since 2002, which has formed the basis for several pieces of published research.
In
the model used in this study, although rapamycin had an anti-angiogenic effect (as indicated for example by less blood vessel formation in the injured site), it did not delay wound closure or affect wound healing.
The model used in the study provides estimates based on vital registration data and from high quality literature on causes of child deaths.
The paper provides a geologically long - term perspective on recent temperature changes in the Northern Hemisphere and the ability of climate models, such as the National Oceanic Atmospheric Administration and National Center for Atmospheric Research (NCAR)
models used in the study, to predict the changes,» says Shuman, senior author on the paper and Marsicek's supervisor.
CSIRO, the Bureau of Meteorology and the ARC Centre of Excellence for Climate System Science developed the Australian Community Climate and Earth System Simulator (ACCESS)
model used in this study in partnership.
The model used in the study could also help researchers estimate populations of protected species present in others area of potential impacts, such as from fisheries, energy extraction operations, and military exercises.
Readers are welcome to download
the model used in our study and to explore the issues using an easy - to - use interface.
The precision of
the models used in the study could be a «significant issue», adds Dr Dave MacLeod, a postdoctoral research assistant at the University of Oxford, who was also not involved with the research.
The 22 climate
models used in this study are the same models used by the UN Intergovernmental Panel of Climate Change (IPCC), which recently shared a Nobel Peace Prize with former Vice President Al Gore.
Here you can see the observed changes in maximum, minimum, mean global temperature, and DTR vs. predictions by the four climate
models used in the study.
