A new study indicates that anxiety about social and economic collapse due to climate change is pervasive in Australia. The nationwide survey (commissioned by the author and carried out by Roy Morgan Research) reveals that nearly a third of Australians are ‘very or extremely concerned’ about social and economic collapse occurring by 2050. Three in five Australians (60 per cent) are at least moderately concerned.

A new study finds two persistent mental shortcuts—not ignorance—are why people keep overrating recycling and underrating flying less.

Methane emissions from Siberia have more than doubled over the past decade, according to new research co-led by scientists at the University of Edinburgh’s National Centre for Earth Observation (NCEO)

Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress

A Climate Rights International report exposes the increasingly heavy-handed treatment of climate activists in Australia, Germany, France, the Netherlands, Sweden, the UK and the US. It found the crackdown in these countries – including lengthy prison sentences, preventive detention and harassment – was a violation of governments’ legal responsibility to protect basic rights to freedom of expression, assembly, and association. It also highlights how these same governments frequently criticise regimes in developing countries for not respecting the right to protest peacefully.

Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration

World is approaching point where no one can shut down a rogue AI, says director of body behind research

Scenarios serve as a critical tool in climate change analysis, enabling the exploration of future evolution of the climate system, climate impacts, and the human system (including mitigation and adaptation actions). This paper describes the scenario framework for ScenarioMIP as part of CMIP7. The design process has involved various rounds of interaction with the research community and user groups at large. The proposal covers a set of scenarios exploring high levels of climate change (to explore high-end climate risks), medium levels of climate change (anchored to current policy), and low levels of climate change (aligned with current international agreements). These scenarios follow very different trajectories in terms of emissions, with some likely to experience peaks and subsequent declines in greenhouse gas concentrations in this century. An important innovation is that most scenarios are intended to be run, if possible, in emission-driven mode, providing a better representation of the Earth system uncert

The process of relocating people from New Orleans should start immediately, as the city has reached a “point of no return” that will see it surrounded by the ocean within decades due to the climate crisis, a stark new study has concluded. Ongoing sea-level rise and the rampant erosion of wetlands in southern Louisiana will swallow up the New Orleans area within a few generations, with the new paper estimating the city “may well be surrounded by the Gulf of Mexico before the end of this century”.

Sixty-five million people will die from pollution caused by nuclear energy and weapons programs built before 1989, according to a report published earlier this year by a European scientific committee. The research, from the European Committee on Radiation Risk (ECRR), raises doubts about previous estimates of the risk posed to humans from exposure to radiation from nuclear power and weapons. The study by the ECRR, based on a risk-assessment model developed over the past five years, challenges previous assumptions about the safety of even minimum exposure to low-level radiation.
