New study determines Earth’s climate sensitivity from recent global warming

The key numbers that climate scientists seek for predicting future global warming are the Earth’s transient- and equilibrium climate sensitivities which are the near- and long term temperature response to a doubling of atmospheric carbon dioxide. Uncertainties in these properties have long been limiting the ability to project future climate change. Recent focus has been … Read more

UQ research contributes to international climate change guidelines

The International Panel on Climate Change has used University of Queensland research to update its National Greenhouse Gas Inventories Guideline for the first time in 13 years. UQ’s Advanced Water Management Centre has spent a decade researching greenhouse gas emissions from wastewater systems, both in lab-scale and full-scale, in close collaboration with its many utility … Read more

Ocean ecosystem recovery after the Cretaceous/Paleogene mass extinction

How long does it take ecosystems to recover from mass extinction and to become functional and resilient again? A team, including Samantha Gibbs from the University of Southampton, and researchers from the universities of University College London, Bristol, Frankfurt and California have tackled that question by producing an unprecedented record of the biotic recovery that … Read more

Girt by sea, Australia faces serious climate challenge

The latest report from the Intergovernmental Panel on Climate Change paints a grim picture of the future of Australia’s coastal areas, but there’s still time to avoid the worst scenario, experts from The Australian National University (ANU) say. Associate Professor Nerilie Abram, a climate change scientist from ANU, is a Co-Ordinating Lead Author of the … Read more

Is theory on earth’s climate in the last 15 million years wrong?

A key theory that attributes the climate evolution of the Earth to the breakdown of Himalayan rocks may not explain the cooling over the past 15 million years, according to a Rutgers-led study. The study in the journal Nature Geoscience could shed more light on the causes of long-term climate change. It centers on the long-term cooling that … Read more

Preventing climate change cheaper than dealing with its damage

World leaders need to urgently accelerate efforts to prevent “profound, if not catastrophic” climate change in future, a distinguished group of scientists has warned. According to their new study published in Science today, acting to reduce climate change would cost much less than repairing the damage it would inflict in coming decades on people, infrastructure and ecosystems. … Read more

Cutting emissions gradually will avert sudden jump in warming

Reducing fossil fuel emissions steadily over coming years will prevent millions of premature deaths and help avoid the worst of climate change without causing the large spike in short-term warming that some studies have predicted, new analysis by researchers at Duke University and the University of Leeds finds. “We analyzed 42 scenarios presenting different timescales … Read more

Geochemists measure new composition of Earth’s mantle

What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior often provide such information. Geochemists at the Universities of Münster (Germany) and Amsterdam (Netherlands) have investigated the volcanic rocks that build up the … Read more

Earth Commission to identify risks, guardrails, targets for entire planet

Three of the world’s foremost scientists will co-chair a commission of leading international experts to identify risks and develop a coherent suite of scientific targets to protect Earth’s life support systems. Johan Rockström, Joyeeta Gupta, and Dahe Qin will co-chair the Earth Commission, comprising an initial 19 members, announced today by the international research organisation … Read more
