Enhancing Climate Change Predictions: Introducing the Time Variability Correction Method

July 15, 2024 11:34 am Published by Comments Off on Enhancing Climate Change Predictions: Introducing the Time Variability Correction Method

Accurate projections of climate change and associated extreme events under differing emission scenarios are linked to realistic representations of the temporal variability of the atmosphere at a variety of time scales. A new paper by Shao et al. (2024) introduces a novel time variability correction method designed to diagnose and rectify variance errors across a range of time scales.

Great Barrier Reef: how the MJO and ENSO contribute to coral bleaching events

July 12, 2024 11:49 am Published by Comments Off on Great Barrier Reef: how the MJO and ENSO contribute to coral bleaching events

Corals are particularly sensitive to weather conditions over the Great Barrier Reef. Researchers from the ARC Centre of Excellence for Climate Extremes have found that the Madden-Julian Oscillation and the El Niño-Southern Oscillation influence weather patterns over the region, contributing to the rising threat of coral bleaching.

 Less than 4% of dryland areas will turn into desert under climate change, new study shows

Climate scientists have found that the increase in aridity in drylands in response to climate change won't lead to a general loss of vegetation productivity. Instead, most of the global drylands are projected to become greener and more productive with climate change.

“I felt I would have a larger impact as a climate researcher”: Aditya Sengupta’s transition from physics to climate science

Aditya Sengupta is a PhD researcher at the ARC Centre of Excellence for Climate Extremes studying the impacts of climate change on El Niño. After studying physics in India, and driven by the desire to make a change, Aditya decided to shift to climate science.

Tonga’s volcanic eruption could cause unusual weather for the rest of the decade, new study shows

The 2022 Hunga Tonga volcanic eruption produced the equivalent of 60,000 Olympic swimming pools of water vapor, which ended up in the stratosphere. Researchers have studied its impact on climate and suggest that it could lead to unusual winter weather for years to come.

Floating robots reveal just how much airborne dust fertilises the Southern Ocean – a key climate ‘shock absorber’

May 16, 2024 1:21 pm Published by Comments Off on Floating robots reveal just how much airborne dust fertilises the Southern Ocean – a key climate ‘shock absorber’

Researchers have found that windblown dust delivers enough iron to support a third of the Southern Ocean’s phytoplankton growth. This finding sheds light on the vital role that dust-fuelled productivity plays in the ocean's capacity to absorb and store carbon dioxide from the atmosphere.

Why did rainfall increase in the third year of the recent triple-dip La Niña?

May 9, 2024 3:09 pm Published by Comments Off on Why did rainfall increase in the third year of the recent triple-dip La Niña?

It seems counterintuitive that rainfall increases in the later years of a multi-year La Niña event. Yet, this is what occurred during the recent triple-dip La Niña. Even more interestingly, this increase happened despite no strengthening of La Niña in the tropical Pacific. So, what's the reason behind it?
