Abstract

This CS2 assignment asks students to implement a literal flood fill. Students are given a terrain containing bodies of water, then write a flood fill algorithm to determine what parts of the terrain will be under water as sea levels rise. Our provided starter files include terrains from around the world and allow students to explore how coastal areas will be impacted by differing amounts of sea level rise. The underlying model is very simple - students see the terrain as a 2D array of real numbers representing heights in meters, and water can flow in each of the four cardinal directions. The resulting images give a striking sense of how coastal areas may be impacted by climate change.

Abstract
Soil erosion, expected to increase with the potential effects of climate change, is the main problem that reduces the useful storage capacity of river dam reservoirs. This problem threatens the safety and sustainability of water and ...
Do rising temperatures always increase forest productivity? Interacting effects of temperature, precipitation, cloudiness and soil texture on tree species growth and competition

Forest landscape models (FLM) are increasingly used to project the effects of climate change on forested landscapes, yet most use phenomenological approaches with untested assumptions about future forest dynamics. We used a FLM that relies on first ...
London broil? The UK's capital prepares for rising tides and temperatures

London already has a barrier in place to seal the River Thames from the sea in time of need, and it is now launching a multibillion-pound project to augment the barrier against the higher tides that the UK government believes warmer weather will hurl ...
