Government subcommittee report examines climate change impact on U.S. financial system

September 10, 2020

WEST LAFAYETTE, Ind. – Managing Climate Risk in the U.S. Financial System, unanimously approved by the U.S. Commodity Futures Trading Commission’s Climate-Related Market Risk Subcommittee, is the first-of-its-kind effort from a U.S. government entity. The report, which presents 53 recommendations, concludes that climate change poses a major risk to the stability of the U.S. financial […]

climate change impacts energy and water demand in the midwest US

How will climate change affect energy use in cities?

July 15, 2020

WEST LAFAYETTE, Ind. — In 2014, residents of Phoenix were asked to plant drought-tolerant plants to conserve water. But the change in vegetation actually made the air feel hotter, leading to residents using more air conditioning powered by water-generated electricity. The point: Without a better understanding of how climate change affects the connection between energy […]

Bubbling methane emissions caused by ice-free days in Arctic lakes

Bubbling methane emissions caused by ice-free days in Arctic lakes

July 6, 2020

WEST LAFAYETTE, Ind. — Although the Arctic is best known for frozen tundra, it also has a number of freshwater lakes that are covered in ice most of the year. But the length of time they are ice-covered is decreasing, and this is allowing methane to bubble into the atmosphere. Globally, lakes are responsible for […]

Forests in Europe and Asia at greater risk of damaging cold snaps

May 12, 2020

ETH researchers find climate change is increasing the risk of late-spring frost in areas where plants are not adapted to this kind of temperature swing, putting some forests of Europe and Asia at higher risk of damage. Climate change is putting temperate trees in Europe and Asia at greater risk to late-spring cold snaps—which threatens […]

Balancing impacts of range-shifting species: Invasives vs biodiversity

May 1, 2020

Ecologists urge greater discussion on consequences of range-shifting species AMHERST, Mass. – For many years, the conservation community has embraced the idea that improving connectivity, that is, creating corridors so species can follow their preferred climate, will benefit biodiversity, says Toni Lyn Morelli at the University of Massachusetts Amherst’s Climate Adaptation Science Center. But, she […]

Analysis: Wind energy expansion would have $27 billion economic impact

April 16, 2020

WEST LAFAYETTE, Ind. — Wind, which generates less greenhouse gas emission than burning fossil fuels, is making up an increasing share of the energy production portfolio in the United States. But wind is not as efficient as coal or natural gas, causing some concern about its economic impact. A Purdue University study that models increased […]

Model to better predict how much heat waves will make Americans crank up the AC

April 15, 2020

WEST LAFAYETTE, Ind. — During heat waves, people tend to crank up their home’s air conditioning not only because it got hotter outside, but also because it feels too humid. To more accurately predict how climate change will affect home electricity use during the summer, researchers have developed a model that takes into consideration how […]
