Research Brief: Regional variations in projections of recent changes in the western boundary currents

November 24, 2021 12:44 pm Published by Comments Off on Research Brief: Regional variations in projections of recent changes in the western boundary currents

Strong ocean currents are found on the western side of the ocean basins, which flow from the tropics toward the poles in both hemispheres. These western boundary currents have shown strong changes in the last few decades, resulting in intensified ocean warming and are projected to amplify further in the future.

Research brief: Measuring spread in spatio-temporal changes of ocean heat content estimates

90% of the heat trapped on Earth by anthropogenic greenhouse gasses is absorbed by the ocean, with the unfortunate by-product of thermosteric sea level rise - as the ocean warms, it expands. Therefore, it is essential that we can accurately measure how much heat the ocean is absorbing over time.

Research Brief: Seasonal and Interannual Variability of the Weddell Gyre

November 1, 2021 4:57 pm Published by Comments Off on Research Brief: Seasonal and Interannual Variability of the Weddell Gyre

The Weddell Gyre, located east of the Antarctic Peninsula, is one of the largest features of the ocean circulation of the Southern Hemisphere. A deeper understanding of the dynamics in this remote region will shed light on the role of the gyre in our present climate and help us understand its potential evolution with climate change.

COP26 will not keep temperatures below 1.5°C and maybe not 2°C

October 25, 2021 9:13 am Published by Comments Off on COP26 will not keep temperatures below 1.5°C and maybe not 2°C

The Glasgow Climate Conference of Parties, COP26, is almost certain to fall short of its first goal to “keep 1.5°C within reach”. Moreover, even if it achieved its other aim to “secure global net-zero by mid-century” there is still a high probability that global temperatures will exceed 2°C if this isn’t matched by increased short-term action as well. That’s the message coming from climate scientists from the ARC Centre of Excellence for Climate Extremes (CLEX).

Briefing note 17: Could understanding the Indian Ocean improve climate predictions for Australia?

You may have heard about the influence of sea surface temperatures (SSTs) in the tropical Pacific Ocean on Australia’s climate and how forecasts of the El Niño–Southern Oscillation (ENSO) help to give warnings of flood, drought and bushfire risk in Australia months in advance… but what about the tropical Indian Ocean?

Research brief: Ekman Streamfunction a strong indicator of overturning circulation strength & variability

October 7, 2021 2:30 pm Published by Comments Off on Research brief: Ekman Streamfunction a strong indicator of overturning circulation strength & variability

CLEX researchers used a state-of-the-art global ocean-sea-ice model to directly measure the overturning circulation, and through this to examine the relationship between the Ekman Streamfunction and the Southern Ocean overturning circulation.
