This paper examined the likelihood of extreme marine heatwaves global using climate models simulations, with and without anthropogenic influences, concluding that these events were up to fifty times more likely due to anthropogenic climate change.
This report is not intended as a “science paper”, rather its designed to translate science into action and highlight risks in the way businesses, the military and emergency services should treat risk when it becomes existential.
The Centre seeks a highly qualified and motivated individual to create new and innovative data assimilation algorithms for discovering model trajectories that closely track observations in the presence of multi-scale, non-linear and non-Gaussian uncertainties such as those associated with observations and forecasts of clouds, precipitation, aerosols, soil moisture, ice, or ocean colour.
The study finds important regional consequences for precipitation and clouds formation if large changes in dimethyl-sulfide emissions were to occur. In a hypothetical case where all marine DMS emissions cease completely, we find the Earth would warm by approximately 0.5 degrees C over a ten-year period.
CLEX researchers found that counter-clockwise rotating eddies in the Southern Ocean mix the ocean deeper in winter, allowing more nutrients to enter their interiors, leading to higher productivity. This work is important because eddy productivity plays a significant role in the exchange of carbon between the ocean and the atmosphere.
This research demonstrates how cloud processes, steep mountains, tropical coastlines, the daily changes in solar insolation and planetary-scale waves work together to cause large variations in the tropical heating that drives global circulation patterns. Many of these effects are under-represented in global climate models.
In this project the vacation scholar will use models, observations and theory to better understand the processes driving ocean heat uptake in the Southern Ocean, with particular applications to sea-level rise.
The ARC Centre of Excellence for Climate Extremes' Heatwave Research Program is holding a full day meeting to explore current research and the future direction of the program.
The past four months since out last newsletter has been tightly packed with the official launch of CLEX, the legacy event for ARCCSS and an acceleration in important research across all of our programs.
The past four months have been incredibly busy with a new research brief structure, big changes in social media, and a mainstream media takeover likely to have significant ramifications for our communication of research.
