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

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

Monday, July 6th, 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…

Providing a local perspective on global climate change

Tuesday, June 30th, 2020

By Abby Leeds  How important is climate change to you personally? This question is guaranteed to produce a wide range of opinions across America. The Yale Program on Climate Change Communication groups the American public into six audiences – alarmed, concerned, cautious, disengaged, doubtful and dismissive. Considering the range of opinions and sometimes misguided information,…

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

Tuesday, May 12th, 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

Friday, May 1st, 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

Thursday, April 16th, 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

Wednesday, April 15th, 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…

Purdue study downgrades Arctic methane emissions thanks to soil microbes

Monday, March 30th, 2020

WEST LAFAYETTE, Ind. — Rising global temperatures are expected to thaw Arctic permafrost, reinvigorating the microorganisms that live in the region’s carbon-rich soils. When that happens, those microbes will begin consuming the carbon stored in the permafrost and emitting massive amounts of methane, one of the most powerful greenhouse gases on the planet. This injection…

More accurate climate change model reveals bleaker outlook on electricity, water use

Monday, March 9th, 2020

WEST LAFAYETTE, Ind. — By 2030, global warming alone could push Chicago to generate 12% more electricity per person each month of the summer. If the city generated any less electricity, it would be risking a power shortage that may require drastic measures to avoid rolling blackouts, according to projections from a model designed by…
