Canadian Arctic warmest in 115,000 years

February 12, 2020

Arctic temperatures are increasing faster than the Northern Hemisphere average due to strong self-reinforcing feedbacks unique to polar regions. This warming is causing rapid retreat of the region’s glaciers, especially in the Eastern Canadian Arctic, however the degree to which this recent warming is unprecedented remains unclear. To address this knowledge gap, Professor Nat Lifton […]

Climate change enhances economics of conservation tillage

February 12, 2020

Farmers have traditionally used intensive tillage to prepare the ground for the next year’s harvest and for weed control. Intensive tillage, however, adversely affects the soil in a field and it leads to sediment and nutrient runoff resulting in pollution of surface water and increased emissions of greenhouse gases. Changing weather patterns associated with climate […]

The growing risk to the U.S. electricity grid

January 27, 2020

A secure and resilient electric grid is vital to national security, a strong economy, and critical services like those provided by water utilities and hospitals. As the demand for power continues to grow, the aging U.S. grid is being stretched to capacity. Moreover, supply risk can result from climate-induced shifts in electricity use and/or damaged […]

Assessing progress towards the Paris Agreement

December 17, 2019

When 195 countries signed the Paris Agreement on Climate Change, they committed to keeping global mean temperature increase below 2 degrees Celsius from pre-industrial levels by the end of the century and to make efforts to limit the rise to below 1.5 degrees.  Instead of setting legally binding emission reduction targets, however, the agreement relies […]

Climate change implications for tourism in the U.S. Great Lakes and Midwest

November 17, 2019

Because the Great Lakes are so large and deep, they influence local and regional weather and climate, which, in turn, influence things like agricultural practices, shipping, and tourism. Winter tourism, for instance, is highly dependent on temperature, snow cover, snowfall, length of the snow season, and the presence or absence of snow during winter holidays. […]

High‐resolution climate projections for the northeastern U.S.

October 1, 2019

Earth system models are able to simulate the interactions of the atmosphere, ocean, land, ice, and biosphere to estimate the state of the global climate under a variety of conditions and for past, present, and future time periods. These models, however, are not able to provide detailed analysis of climate change at regional and local […]

Amazonian peatlands could shift from a carbon sink to a carbon source under a changing climate

August 1, 2019

Amazonian peatlands store a large amount of soil organic carbon (SOC). These natural carbon “sinks” keep carbon dioxide (CO2) out of the atmosphere, and, when left undisturbed, peatlands store more carbon dioxide than all other vegetation types on Earth combined.  But when they are drained and deforested, they can release large amounts of heat-trapping gases […]

Reconstruction of past climate provides clues about future climate change

June 24, 2019

Sediment cores drilled from the seafloor by the JOIDES Resolution research vessel helped researchers create a timeline of temperature throughout the Eocene. New research results indicate that greenhouse gases were the main driver of climate change throughout the Eocene, a period of time between 56 million years and 34 million years ago, and a time that […]

Severe thunderstorms are expected to occur more often in a warmer climate

May 27, 2019

Commonly known as thunderstorm, hazardous convective weather (HCW) such as damaging wind gusts, large hail, tornadoes and flash flooding, pose a significant threat to life and property and remain a prominent source of weather-related losses in the United States. While the risk for weather disasters certainly increases as the population grows and people move into […]

The ecology of peace: preparing Colombia for new political and planetary climates

May 22, 2019

Current efforts for achieving peace in Colombia and ongoing changes in global climate will combine to shape the future of Colombia’s tropical forests, one of Earth’s biodiversity hotspots. A new paper led by Alejandro Salazar (PhD 2017, Biological Sciences; currently a postdoc researcher at the University of Iceland) examines the potential impacts of these transformative events, […]
