soil carbon and climate change

The impact of land-use change on carbon retention in deep soil layers

June 12, 2020

Microbial residues play an important role in soil carbon sequestration, but little is known about the impact of land-use changes on these residues in deep soil layers. Professor Timothy Filley ( Department of Earth, Atmospheric, and Planetary Sciences and the Department of Agronomy) and colleagues studies the effect of converting grassland to cropland in a […]

Tropical cyclone in a changing climate

Improving representation of tropical cyclones in climate prediction models

June 11, 2020

Scientists have evidence that concludes human-driven global warming is causing tropical cyclones (TCs) to produce greater amounts of rainfall, and it is believed that TCs are a major contributor to the observed increases in extreme precipitation in the United States. Professor Dan Chavas ( Department of Earth, Atmospheric, and Planetary Sciences) and co-authors developed a […]

reduce GHG emissions with bike sharing

Bike share systems provide GHG reductions in major U.S. cities

June 11, 2020

Professor Hua Cai (School of Industrial Engineering and the Division of Environmental and Ecological Engineering) and colleagues analyzed bike share systems in eight major U.S. cities and calculated the annual reduction in greenhouse gas emissions from this increasingly popular mode of transportation. Larger bike sharing systems with higher usage intensity saw the greatest GHG reductions. […]

climate change outpaces community tree migration

Climate change is outpacing the rate of community forest migration

June 11, 2020

Climate change has impacted forest ecosystems, leading to species‐level tree migration. However, the impacts of climate change on forest communities are mostly unknown. A study led by Dr. Jonathan Knott (PhD, 2020, Forestry & Natural Resources) analyzed changes to forest communities at three scales: within‐community changes in species composition, individual community spatial shifts and changes […]

Water recycling in agricultural landscapes

May 18, 2020

Drained agricultural landscapes within the U.S. Midwest are faced with the challenge of addressing both excess and deficit water conditions, often within the same year, while also minimizing negative impacts on water quality and the environment. Drainage water recycling, the practice of capturing and storing water drained from fields and using the stored water to […]

Making influence visible at the Paris Climate Summit

March 4, 2020

Studies of power and influence at sites of global environmental governance often overlook the role of Indigenous Peoples in the agreement-making processes. This limits our understanding of these processes and how they can be shaped for more effective, inclusive and just global governance. A research team led by Professors Laura Zanotti (Anthropology) and Kimberly Marion […]

Ice nucleating particles on the Arctic are on the rise

March 4, 2020

Atmospheric aerosol particles that can trigger ice formation in clouds are referred to as Ice Nucleating Particles (INP). The frequency and properties of clouds in the Arctic are especially sensitive to concentrations of INPs, yet the main sources and concentrations of INPs in this region remain uncertain. Over the past 30 years, warming in the […]

Policy priorities for achieving China’s mitigation goals

March 4, 2020

China is the world’s largest emitter of CO2. As the largest sector of China’s fossil energy consumption and carbon emissions, manufacturing will play an important role in achieving emission reduction goals in China. Three main types of energy-related CO2 mitigation policies are anticipated to be implemented in the coming years: fuel substitution, improved energy efficiency, […]

Global change is impacting important plant-fungi associations

February 14, 2020

In the forests of North America, a mutualistic relationship exists between trees and mycorrhizal fungi—fungi supply trees with nutrients and trees provide carbon to fungi. It is well documented that these forests are experiencing unprecedented change due to a combination of stressors including climate change, nitrogen deposition, habitat fragmentation, invasive species and fire suppression; however, […]

Emissions trading: auctioning vs grandfathering permits

February 12, 2020

Emissions trading programs are increasingly used as market based climate policy instruments to reduce greenhouse gas emissions cost-effectively. Under these programs, a national or regional limit (cap) is placed on the total amount of emissions across a given industry, or the whole economy. The total amount is split into allowances, each permitting a company to […]
