Latest science on the 1.5°C limit of the Paris Agreement

This briefing provides a comprehensive overview of what the science is saying now about the 1.5°C warming limit – what it means, what is at stake, and what actions are needed to limit the risks of overshoot and safeguard a liveable future.

Tracking what matters: SIDS priorities for global adaptation indicators

This briefing helps SIDS advocate for global adaptation indicators that catalyse support, investment, and political will to scale up adaptation responses, not just track them.

The full implications of Australia's North West Shelf decision

On 28 May 2025, Australian Environment Minister Murray Watt made the first step towards what looks set to be a final decision to approve Woodside Energy's North West Shelf LNG plant in Western Australia through to 2070.

Climate overshoot implications for local adaptation planning

New perspective piece argues climate overshoot – the temporary exceedance of the 1.5°C limit of the Paris Agreement – may not be relevant for short-term adaptation planning, but it should be considered for long-term plans and policies, such as infrastructure-based measures and for irreversible impacts such as sea-level rise.

Addressing challenges in the land sector under the Paris Agreement

This report examines how loose land-sector rules under the Paris Agreement enable countries to overstate carbon removals and delay essential fossil fuel emissions cuts.

The impact of global climate pledges on national action: a snapshot across Asia

A detailed analysis of eight Asian countries' climate action compared with global pledges.

Fair carbon removal obligations under climate response uncertainty

We assess the level of ‘preventive’ CDR needed to draw warming down to 1.5°C in case of a stronger-than-average Earth System response.

A Practical Guide to Understanding and Establishing Climate Finance Units

This policy brief provides actionable insights for the development and effective implementation of Climate Finance Units within governments to mobilise and coordinate climate finance in alignment with national goals.

Reversal of the impact chain for actionable climate information

This study helps local decision-makers understand the link between the risks they want to avoid (i.e. health-related heat risks) and CO2 emissions using a new method that makes identifying critical risk levels easier for non-scientists.

Humid heat exceeds human tolerance limits and causes mass mortality

With critical physiological limits to human heat tolerance drawing ever closer, this Comment highlights the urgent need to limit further climate warming and emphasises the adaptation challenge ahead.

1.5°C-aligned 2030 and 2035 GHG emissions targets

We have produced factsheets for Australia, Brazil, China, the EU, India, Indonesia and USA showing 2030 and 2035 greenhouse gas emission reduction milestones for each jurisdiction to align with the Paris Agreement’s 1.5°C goal – both including and excluding land use, land-use change and forestry.

Spatially resolved emulated annual temperature projections for overshoot pathways

This study presents a new dataset of annual temperature projections for different overshoot pathways (when the 1.5 °C of global warming limit is exceeded). The data offers a unique opportunity to study local and regional climate change impacts of a range of overshoot scenarios, including when temperature thresholds might be exceeded, and by how much.
