Quantification of the uncertainties in future climate projections is crucial for the implementation of climate policies. Here a review of projections of global temperature change over the twenty-first century is provided for the six illustrative emission scenarios from the Special Report on Emissions Scenarios (SRES) that assume no policy intervention, based on the latest generation of coupled ...

This paper outlines methods to perform basic spatial operations on 2D digital images that have been mapped into an equivalent set of digital projections. The digital projections are generated using the Discrete Radon Transform (DRT). Each digital projection is similar to an oriented straight-line integral of the Radon transform and the set of digital projections resembles the sinogram from clas...

Future increases in flooding potential around the world’s coastlines from extreme sea level events is heavily dependent on projections of future global mean sea level (GMSL) rise. Yet, the two main approaches for projecting 21st century GMSL rise—i.e., process-based versus semi-empirical—give inconsistent results. Here, a novel hybrid approach to GMSL projection, containing a process-based ther...

Understanding uncertainties in land cover projections is critical to investigating land-based climate mitigation policies, assessing the potential of climate adaptation strategies and quantifying the impacts of land cover change on the climate system. Here, we identify and quantify uncertainties in global and European land cover projections over a diverse range of model types and scenarios, ext...

11 Large biases associated with climate projections are problematic when it comes to 12 their regional application in the assessment of water resources and ecosystems. Here, we 13 demonstrate a method that can reduce systematic biases in regional climate projections. 14 The global and regional climate models employed to demonstrate this technique are the 15 Community Climate System Model (CCSM)...

Quantitative scenarios are coming of age as a tool for evaluating the impact of future socioeconomic development pathways on biodiversity and ecosystem services. We analyze global terrestrial, freshwater, and marine biodiversity scenarios using a range of measures including extinctions, changes in species abundance, habitat loss, and distribution shifts, as well as comparing model projections t...
