Altered Precipitation

The amount, distribution and timing of precipitation events is changing. In general, precipitation events are occurring less frequently, but are more likely to be intense.

Altered Water Levels

Increasing temperatures have been observed to lead to reduced lake levels due to increased evaporation. Altered water levels can negatively impact people and the environment.


CanVis is a simple software program that allows users to visualize potential impacts of coastal development or climate change (inundation, SLR) allowing conservation planners and stakeholders to better understand the impacts of their decisions.

Changing Water Regimes

Impacts of changing water regimes include altered precipitation, altered water levels, and greater flood risk. Together these changes pose management challenges and present conservation opportunities to the land trust community.

Climate Change and Water

The Climate Change and Water website highlights U.S. Environmental Protection Agency (EPA) climate change response actions, regional climate impacts, and additional resources to address climate change impacts to water resources.

Climate Change and Water: In Brief

As the USFS’s Climate Change and Water: In Brief summarizes, declining water quantity and quality are becoming common issues, especially where our demands exceed supply. Growing water demands, in turn, put aquatic resources and other services at risk because less water is available to sustain them.

Coastal Lidar

LIDAR —Light Detection and Ranging — is a remote sensing method used to examine the surface of the Earth. Coastal Lidar reflects elevation information, which is a primary data consideration for management activities in the coastal zone, including conservation.

Greater Flood Risk

Because spring is arriving earlier, snow packs are also melting earlier. This means that many streams and rivers are reaching their peak flows earlier in the season, which, coupled with increasing numbers of high flow days, can present greater flood risks.

Green Infrastructure Mapping Guide

This online, self-guided resource shows spatial analysts how to incorporate green infrastructure into their GIS work to prioritize areas that will help reduce hazard and climate impacts.

Ice melt, sea level rise and superstorms: 2◦ C global warming could be dangerous

Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2◦ C global warming could be dangerous. New research that warns of perilous climate shifts in decades.
