EPA Releases New Report on Green Infrastructure and Climate Change

As different parts of the country become drier, wetter or hotter, community leaders and citizens are
looking to green infrastructure to improve their community's resiliency to the effects of climate change. In
2015, EPA convened charrettes, or intensive planning sessions, in four cities to demonstrate how this
type of planning could be applied to communities dealing with a range of challenges. Each city's charrette
focused on different issues based on the most pressing climate change impacts they were facing and
their current level of green infrastructure implementation. This new publication summarizes those issues
and the recommendations developed by each charrette.

EPA Kicks Off Fifth Annual Campus RainWorks Challenge

The Campus RainWorks Challenge asks student teams to design innovative green infrastructure for their
campus. This year teams will incorporate climate resiliency and consider community engagement in their
green infrastructure designs for stormwater management. EPA is calling for college and university
students to form teams with a faculty advisor and compete in either the master plan or demonstration
project categories. Registration will be open from September 1-30, 2016. Entries are due December 16,
2016.

New Climate Projections Aim to Better Represent Extreme Events

The U.S. Geological Survey released a next-generation climate modeling dataset with improved local-
scale climate projections from northern Mexico to southern Canada. The dataset uses a new downscaling
method known as Local Constructed Analogs to estimate finer-scale climate details from coarse-
resolution CMIP5 models by using a high-resolution historical observation dataset. Investigations of
changes in intensity and frequency of extreme weather conditions are also provided.

Access the Dataset.

Fourth National Climate Assessment Author Nominations and Technical Inputs

Nominations for regional and sectoral chapter lead authors, and contributing authors with relevant subject
matter expertise, for the Fourth National Climate Assessment (NCA4) are now open. Technical inputs on
sectoral, regional, and cross-cutting topics, which will serve as part of the foundation for NCA4 can also
be submitted at this time. Author Nominations Due: September 30, 2016. Scientific and Technical Inputs
Due: January 15, 2017.

Nominate an Author and Provide Technical Input.

Shifting Sport Fish Populations Under Climate Change

Warming water temperatures will likely mean fewer walleye and more largemouth bass in Wisconsin
lakes, according to a new publication in Global Change Biology. The researchers supported by the
National Climate Change and Wildlife Science Center, predicted future habitat suitability for walleye and
largemouth bass in over 2,100 lakes, identifying where walleye populations might be resilient to future
changes and a good target for management action.

Atmospheric River Landfall-Latitude Changes in Future Climate Simulations

A recently published study examined climate simulations of atmospheric rivers in the North Pacific and
the North Atlantic using version 4 of the Community Climate System Model. The study found that the
atmospheric rivers along the west coast of the U.S. are projected to move toward the equator and
experience increased rainfall intensity and the projected landfall to be more dependent upon eddy-driven
jets and seasons.

Fish Adjusting Body Defenses to Deal with Acidification

A recently published study examined the natural ability offish to adapt to changes in ocean acidification.
Spiny damselfish are capable of adapting to higher CO2 levels as part of the genetic mechanisms

organizing their circadian clocks. This natural ability is driven by the need to accommodate the diurnal
variation in ocean CO2 levels that occurs with the inactivity of photosynthesizing organisms at night.

Urban Stream Quality Assessment Model

A recently published report focuses on the effect of landscape alteration and climate change on total
suspended solids (TSS), total phosphorus (TP) and temperature in catchment areas of the Puget Sound.
Preliminary results suggest urbanization will have a greater effect than climate change on the magnitude
and seasonal variability of streamflow. Water temperature will be more sensitive to climate warming
scenarios. Future urbanization and climate change are predicted to significantly increase annual mean
streamflow, water temperature, TSS load, and TP load.

Rising Tides: Designing Resilient Amenities for Coastal Cities

Market demand is the best driver for innovation, and many are making a case that the intrinsic economic
value of resilient design will help drive its acceptance. The collision of forces between the need for
resilience and the cost of it is producing sparks of creativity, particularly in the area of waterfront and
storm-related planning. Far from a defensive role, resilience can be part of a project's marketing strategy
and mission.

Review of the Significance of Dissolved Methane on Wastewater Treatment

A recently published article discusses the need for energy efficient domestic wastewater (DWW)
treatment that is increasing annually with population growth and expanding global energy demand. A
model for estimating energy consumption associated with membrane-based dissolved methane recovery
predicts that recovered dissolved and headspace methane may provide all the energy required for
operation of an anaerobic system treating DWW at cold temperatures.

Successful Simulation of the Pineapple Express

A publication in the Geophysical Research Letters synthesizes the ability of the Community Climate
System Model (CCSM4) to capture the Pineapple Express, an atmospheric river that originates in the
deep tropics and extends poleward along the west coast of North America. Recent analysis of the
CCSM4 high-resolution ensemble simulations shows accurate capture of the spatial and temporal
climatology. Further analysis of these simulations indicates a significant increase in storm duration and
intensity of precipitation associated with landfall of the atmospheric river.
