Sea-level rise is a major consequence of climate change that will continue long after emissions of greenhouse gases have stopped. The 2015 Paris Agreement aims at reducing climate-related risks by reducing greenhouse gas emissions to net zero and limiting global-mean temperature increase. This study quantifies the effect of these constraints on global sea-level rise until 2300, including Antarctic ice-sheet instabilities.
Peer-reviewed Papers
This article identifies and quantifies the 10 most important benchmarks for climate action to be taken by 2020–2025 to keep the window open for a 1.5°C-consistent GHG emission pathway.
Briefings
There have been proposals for the UNFCCC to adopt a dual-term greenhouse gas accounting standard: 20-year GWPs alongside the presently accepted 100-year GWPs. It is argued that the advantage of such a change would be to more rapidly reduce short term warming and buy time for CO2 reductions. This briefing shows why these changes would be counterproductive and the benefits overstated.
Reports
While there is a significant improvement on climate action globally, despite US rollbacks, President Trump’s announced intention to withdraw from the Paris Agreement, has led to a significant deterioration in the effect of Paris Agreement commitments (NDCs)—by about 0.3°C.
Briefings
This briefing provides an overview of the latest science on key risks for ocean systems including from sea-level rise, ocean acidification and impacts on coral reefs and other marine and coastal ecosystems.
Reports
The UN Environment Emissions Gap Report 2017 presents an assessment of current national mitigation efforts and the ambitions countries have presented in their Nationally Determined Contributions, which form the foundation of the Paris Agreement.
