My research focuses on how the Earth’s climate has behaved over the last millennium, and what that tells us about the climate changes we are seeing now. The past climate records that I develop come from corals, caves and ice cores, and I combine these with climate model data to study climate changes.
My research is supported by a Queen Elizabeth II research fellowship and Discovery Projects from the Australian Research Council. I'm also an Associate Investigator with the ARC Centre of Excellence for Climate System Science (ARCCSS) and I'm actively involved in a number of the international reconstruction teams for the Past Global Changes 2k projects.

Early onset of industrial-era warming across the oceans and continents
Instrumental records of temperature provide unambiguous evidence for climate warming caused by greenhouse gas emissions during the 20th and 21st Centuries. But is this the full picture? Using palaeoclimate reconstructions and simulations spanning the last 500 years, this research finds that industrial-era warming first began in some parts of the world as early as the 1830s. The small but measureable response of Earth's climate to rising greenhouse gas levels during the 19th century needs to be considered to fully account for how much and how quickly humans have altered our climate.

Tropical sea-surface temperatures for the past four centuries reconstructed from coral archives
Reconstructions of natural and human-induced climate change over the last millennium are primarily derived from land-based records, making it difficult to assess how climate changes have evolved across the large areas of ocean that cover the Earth. In this study, an international team of researchers has synthesised annually resolved coral records to produce sea surface temperature histories over four tropical ocean regions. The work is part of the Ocean2k project, as part of the wider Past Global Changes 2k initiative (PAGES2k).
Evolution of the Southern Annular Mode during the past millennium
The winds that circle around the Southern Ocean determine how much rainfall falls over southern parts of Australia. These winds also affect the temperature of the ocean and air around Antarctica. This study shows that increasing greenhouse gas levels are causing the Southern Ocean winds to get stronger and pull in tighter around Antarctica, meaning that Australia misses out on winter rain and making parts of the Antarctic ice sheets more susceptible to melting.
Acceleration of snow melt in an Antarctic Peninsula ice core during the twentieth century
This unique record of past ice melt shows that the current levels of melting on the Antarctic Peninsula are higher than at any other time over at least the last 1000 years. Melting has been increasing dramatically since the mid 20th century and the record gives a clear example of the potential for rapid increases in melting to even small amounts of warming in places where summer temperatures are close to 0 degreesC. Read more in the News and Views and The Conversation commentary pieces on this study
Recent Antarctic Peninsula warming relative to Holocene climate and ice-shelf history
The Antarctic Peninsula is warming faster than any other place in the Southern Hemisphere. In this work we developed the first ice core record from the Antarctic Peninsula spanning the full Holocene, showing that the very rapid rate warming in this region over the past 50 years is very unusual in a geological context. Read more in the News and Views and Real Climate pieces written by Eric Steig.
Ice core evidence for a 20th century decline of sea ice in the Bellingshausen Sea, Antarctica
Using the chemical fingerprints in an array of ice cores from around Antarctica this study was able to show the different regional patterns of sea ice retreat around Antarctica over the 20th Century. These long sea ice reconstructions contrast with the short satellite observations of Antarctic sea ice change, which have seen an overall increase in the extent of Antarctic sea ice since the 1980s.

Oscillations in the southern extent of the Indo-Pacific Warm Pool during the mid-Holocene
This study showed that accurate assessments of past ocean temperatures can be obtained by looking at the bulk geochemical signal of large groups of fossil corals. Applying this to corals from offshore of Sumatra and Papua New Guinea showed that the very warm waters that lie to the north of Australia (and are important for bringing rain to parts of the country) have moved closer and further way from Australia at different times during the last 7000 years
Recent intensification of tropical climate variability in the Indian Ocean
This study used corals to extend the short instrumental record of the Indian Ocean Dipole (the Indian Ocean's equivalent to El Nino) back by more than 100 years. This long perspective shows how unusual the recent cluster of strong and frequent IOD events is; whereas these events typically only occurred every 20 years at the start of the 1900s, we are now seeing events roughly every 4 years.
Seasonal characteristics of the Indian Ocean Dipole during the Holocene epoch
Detailed analysis of the chemistry of fossil coral skeletons showed how the temperature and rainfall changes during Indian Ocean Dipole events changed when the Asian monsoon was stronger than today. Understanding the potential for future changes in the duration and intensity of Indian Ocean Dipole droughts will be important for climate change adaption in the Indian Ocean region.
Coral reef death during the 1997 Indian Ocean Dipole linked to Indonesian wildfires
Our team were Eureka Prize finalists for the unique finding that nutrients from wildfires can fertilise the ocean and lead to destructive algal blooms. The findings were based on the death of a 400km long section of reef off the coast of Sumatra following massive wildfires in 2007.
