Fresh Water Becoming Saltier Around the United States

Friday, January 12th, 2018
Fig. 1. Maps showing locations of increasing, decreasing, and/or no trends in specific conductance and pH in stream water throughout the continental United States. Streamlines represent all conterminous US rivers with mean annual discharge exceeding 20 m3 /s (47).

The freshwater salinization syndrome can increase risks to the safety of drinking water and infrastructure. Elevated salt levels in drinking water can contribute to hypertension in people on sodium-restricted diets and is of concern to people requiring kidney dialysis (9). Salinization and alkalinization influence the corrosivity of water, and this can affect leaching of metals from pipes carrying drinking water (9, 68).

U.S. Energy-Related Carbon Dioxide Emissions

Thursday, October 26th, 2017
Figure 1. Energy-related CO2 emissions, 1990–2016

Energy‐related carbon dioxide (CO2) emissions decreased by 89 million metric tons(MMmt), from 5,259 MMmt in 2015 to 5,170 MMmt in 2016. Although real gross domestic product (GDP) increased 1.5% over that period, other factors contributing to energy-related CO2 emissions more than offset the growth in GDP, leading to a 1.7% decline in energy-related CO2.

Funding Trees for Health: An Analysis of Finance and Policy Actions to Enable Tree Planting for Public Health

Monday, October 9th, 2017
Figure E1. Trees and Public health. Conceptual model of the linkage between urban forestry funding and health funding.

The scientific case for the benefits of trees and urban nature has become more solid over the last few decades. Trees and other natural features in cities can help regulate water quality, water quantity, and the timing of water flow. They can help clean and cool the air, reducing harmful air pollutants and ambient air temperatures. They lend beauty to our streets, enhance citizens’ lives, and significantly increase property values. When you consider all the benefits that street trees can provide to society, there is a strong business case for increased societal investment. One study in California, for instance, found that for every $1 spent on tree planting and maintenance, urban trees deliver $5.82 in benefits.
