Good Food is First Food. It is not junk food. It is the food that connects nature and nutrition with livelihoods. This food is good for our health; it comes from the rich biodiversity of our regions; it provides employment to people. Most importantly, cooking and eating give us pleasure. …
Acute flaccid myelitis (AFM) is a neurologic condition characterized by flaccid limb weakness. After a large number of reports of AFM in 2014, the Centers for Disease Control and Prevention began standardized surveillance in the United States to characterize the disease burden and explore potential etiologies and epidemiologic associations. Original …
Global warming is expected to increase the frequency and intensity of severe water scarcity (SWS) events, which negatively affect rain-fed crops such as wheat, a key source of calories and protein for humans. Here, we develop a method to simultaneously quantify SWS over the world’s entire wheat-growing area and calculate …
Although recently published research addresses a range of issues relating to the corn ethanol lifecycle, much attention has focused on the result that corn ethanol production has a significantly better emissions profile than the U.S. Environmental Protection Agency (EPA) concluded in its 2010 regulatory impact analysis for the Renewable Fuel …
This study assesses the fuel efficiency of U.S. airlines on domestic operations in 2017 and 2018. Revenue passenger miles (RPMs) increased 10% and departures increased by 4% from 2016 to 2018. Fuel efficiency in terms of RPMs per gallon of fuel consumed improved by 3%. The net result was a …
Road injuries are among the ten leading causes of death worldwide and also impede economic wellbeing and macroeconomic performance. Beyond medical data on the incidence of road injuries and their resulting morbidity and mortality, a detailed understanding of their economic implications is a prerequisite for sound, evidence-based policy making. We …
To achieve the Paris Agreement goals and limit global temperature rise this century to 1.5°C, the global economy must be rapidly transformed. A carbon price is needed to incorporate climate change costs into economic decision-making to significantly reduce U.S. greenhouse gas emissions, particularly in the electricity sector. However, a carbon …
This study examines the drivers of both the previous decline in global energy-related CO2 emissions, and their subsequent growth in recent years (in the EU, US, India and China), and argues that this trend was in neither case a good indicator of climate policy effort or effectiveness. Global emissions are …

This paper summarizes and compares the two main test methods for aerodynamic evaluations of heavy trucks in the United States and the European Union: coastdown testing and constant-speed testing, respectively. The methodologies were compared in terms of their instrumentation requirements, test-track requirements, testing effort, data analysis and use within simulation …
This paper analyzes the capital costs of the electric vehicle charging infrastructure needed for public, workplace, and home charging for the most populous 100 metropolitan areas in the United States from 2019 through 2025. The 100 metropolitan areas analyzed represent 88% of all new electric vehicles sold and 75% of …
This paper quantifies the infrastructure needs and associated costs for implementing battery electric and hydrogen fuel cell trucks in three applications: long-haul intercity tractor-trailers, drayage trucks, and medium-duty delivery trucks.
The United States has lost the equivalent of nine Grand Canyon national parks, or 24 million acres (9712455.41 hectares) of natural area, between 2001 and 2017 due to agriculture, energy development, housing sprawl and other human factors, making the country more vulnerable to the impacts of climate change, according to …
Evidence indicates that air pollution contributes to cardiopulmonary mortality. There is ongoing debate regarding the size and shape of the pollution–mortality exposure–response relationship. There are also growing appeals for estimates of pollution–mortality relationships that use public data and are based on large, representative study cohorts. Original Source
The transition to electrified transportation is occurring across the United States at different rates due to vehicle model availability, charging infrastructure, government engagement, and other factors. The Midwest region has, so far, not been a leader in electric vehicle sales, but sales are increasing. This briefing takes an in-depth look …
Policies in the European Union, the United States, and Canada support the use of forest biomass in heating, power generation, and transportation as a climate mitigation strategy. However, research conflicts on whether forest bioenergy results in greenhouse gas (GHG) savings in the long-term. This study investigates if there is evidence …
This World Energy Outlook special report examines the role of fuel switching, primarily from coal to natural gas, to reduce emissions of carbon dioxide and air pollutants. Four case studies, covering the United States, the European Union, the People’s Republic of China, and India, reveal the various opportunities, hurdles and …
"Weather is chaotic," said Melissa Lau, a sixth-grade teacher in this bedroom community outside of Oklahoma City. "What does that mean to you?" Another boy addedf: "It's another word for 'crazy. My sister got hit by a golf-ball-sized piece of hail." The students didn't know it yet, but they were …
High desert communities in Southern California on Saturday assessed damage and braced for potentially dangerous aftershocks from a major earthquake that shook buildings, ruptured gas lines and sparked fires near the remote epicenter of the second temblor in as many days. The powerful magnitude 7.1 earthquake rocked the Mojave Desert …
When the Conowingo Dam opened to fanfare nearly a century ago, the massive wall of concrete and steel began its job of harnessing water power in northern Maryland. It also quietly provided a side benefit: trapping sediment and silt before it could flow miles downstream and pollute the Chesapeake Bay, …
This UCS analysis provides a detailed view of how extreme heat events caused by dangerous combinations of temperature and humidity are likely to become more frequent and widespread in the United States over this century. It also describes the implications for everyday life in different regions of the country.
