Predicting how much primary production will further increase in the Arctic Ocean in coming decades depends on the interplay between the increase in light for primary producers, as the sea ice extent and thickness decrease, and the availability of food in the form of nutrients, such as nitrate, phosphate, and silica.

Irrespective of tipping points, climate change adaptation efforts will be less costly and disruptive to society – and will stand a better chance of success – if warming can be limited to 1.5°C rather than 2°C or higher. We therefore in no way advocate for policies that forgo pursuing the ambition to limit global warming to 1.5°C, regardless of whether that target remains feasible or not.
In this project you will investigate the competing effects the Antarctic ozone hole and increasing greenhouse gases have on the Australian summer season rainfall, using the latest climate models. These are now available on the National Computing Infrastructure (NCI) supercomputer and are being used as input into the Intergovernmental Panel on Climate Change’s Sixth Assessment Report.
Briefing note 003: Why are we uncertain about how extremely wet conditions will change in Australia in the future?February 11, 2019 4:08 pm Comments Off on Briefing note 003: Why are we uncertain about how extremely wet conditions will change in Australia in the future?
Computer models used to simulate global climate agree the climate will warm in response to increasing atmospheric greenhouse gases. However, a recent paper by Bador et al. (2018)1 includes results that highlight our uncertainty about exactly how extremely wet conditions will change in Australia. Further development of Australia’s national climate model, ACCESS, may help reduce this uncertainty.
