Limiting warming to 1.5°C is of paramount importance to protect the oceans. 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.

The commonly agreed metric to aggregate emissions and removals of greenhouse gases under the UNFCCC and the Paris Agreement is the Global Warming Potential with a 100-year time-horizon (GWP100). This briefing looks at the pitfalls of applying a new metric, GWP*.

This report estimates this sea-level rise commitment and find that pledged emissions until 2030 lock in one metre of sea-level rise in the year 2300.

This study reviews the climate change–impact literature and provides evidence of the impacts of warming at 1°, 1.5°, and 2°C—and higher—for the physical system, ecosystems, agriculture, and human livelihoods.

This study assesses the changes in the contrasting hydrological regimes of certain Himalayan watersheds and subsequent water availability in Pakistan under 1.5 °C and 2.0 °C pathways.

This briefing lays out the key findings of the IPCC SR15 that inform governments in their task to develop and submit long-term low emission sustainable development strategies, and inform the continuous scaling up of near- and mid-term action and targets, including in Nationally Determined contributions (NDCs), in line with the ratcheting-up mechanism enshrined in the Paris Agreement.
