This POSTbrief provides further information on current projections of future sea level rise. It introduces sea level rise projections and discusses the various future emissions scenarios used in the projections, the different modelling methods employed, as well as the likelihood ranges and uncertainties associated with them. It also provides an overview of the current sea level rise projections arising from different modelling techniques and emission scenarios and discusses high-end sea level rise scenarios.

This POSTbrief accompanies POSTnote 555 Rising Sea Levels.

  • Invasive non-native species

    Research suggests that the threat from invasive non-native species (INNS) is growing. Biological invasions by INNS harm native species and habitats and can have economic impacts. Biosecurity measures can be adopted to prevent the introduction and spread of INNS. This POSTnote summarises the drivers and impacts of INNS and the measures needed to meet national and international environmental targets.

  • Green steel

    Greenhouse gas (GHG) emissions from the iron and steel industry make up 14% of industrial emissions in the UK. Decarbonisation of the steel industry is needed if the UK is to meet its target of net zero GHG emissions by 2050. This POSTnote outlines current steelmaking processes in the UK, the technologies and measures that can be used to reduce CO2 emissions, and the supporting infrastructure and policies that could enable a ‘green steel’ industry in the UK.
