Energy demand, sources will change with Indiana’s climate

February 20, 2019

WEST LAFAYETTE, Ind. – Hoosiers will heat homes and businesses less but rely more on air conditioning as Indiana’s climate warms. They’ll also get more of their energy from natural gas and renewable sources as those become more cost-effective throughout the rest of the century. That’s according to the latest Indiana Climate Change Impacts Assessment […]

Climate drives link between forest biodiversity and productivity

January 24, 2019

WEST LAFAYETTE, Ind. – Some ecologists believe that species richness is positively related to ecosystem productivity, while others conclude that the relationship is bell-shaped or they are unrelated. Using big data, Purdue University scientists now know which theory is correct – all of them. Biodiversity-productivity relationships would be useful to natural resource managers who want […]

To understand climate change, we need to understand weather now

January 22, 2019

WEST LAFAYETTE, Ind. — Climate scientists have known for decades that there’s more to climate change than higher temperatures. Sea levels are rising, wildfires are blazing and droughts are diminishing water supplies across the globe. Extreme weather events, such as hurricanes and thunderstorms, are likely to get worse as well. But in order to predict […]

Purdue-led group prepares state for life with changing climate

January 10, 2019

This past November, Jeff Dukes and Jonathon Day took turns returning phone calls. Reporters from all over Indiana – and some in Illinois and Kentucky – wanted to know what tourism in the state would look like over the coming decades as climate changes. Dukes, director of the Purdue Climate Change Research Center, talked to […]

Why it’s so hard to forecast a white Christmas

December 14, 2018

No matter how you might feel about cold weather, who doesn’t dream of a white Christmas? Every December, forecasts abound on the probability of a snow-filled holiday.  Austin Pearson, Purdue Extension director in Tipton County and climatology expert, said it’s almost impossible to predict Christmas snowfall more than three days in advance. Even 24 hours […]

Major natural carbon sink may soon become a carbon source

November 20, 2018

WEST LAFAYETTE, Ind. — Until humans can find a way to geoengineer ourselves out of the climate disaster we’ve created, we must rely on natural carbon sinks, such as oceans and forests, to suck carbon dioxide out of the atmosphere. These ecosystems are deteriorating at the hand of climate change, and once destroyed they may […]

Longer, hotter summers to challenge Indiana tourism business

November 12, 2018

WEST LAFAYETTE, Ind. – By 2050, a month of the best weather for attracting summer tourists to Indiana will be replaced by hotter days that will be too uncomfortable for outdoor activity. Warmer temperatures will also limit many popular winter activities. That prediction is according to the latest Indiana Climate Change Impacts Assessment report, “Tourism […]

Dry conditions may have helped a new type of plant gain a foothold on Earth

November 8, 2018

Story by Katherine Unger Baillie, University of Pennsylvania In the dramatically changing conditions of ancient Earth, organisms had to evolve new strategies to keep up. From the mid-Oligocene, roughly 30 million years ago, to the mid-to-late Miocene, about 5 million years ago, carbon dioxide concentrations in the atmosphere fell by a roughly a third. This same […]

Climate study points to western Canada as the route of human migration into North America

October 8, 2018

WEST LAFAYETTE, Ind. — When and how the first humans reached North America is a complicated puzzle. Scientists believe these people arrived in Alaska after crossing the Bering Strait, only to be stopped by the enormous Laurentide and Cordilleran ice sheets. The migrants would eventually make their way down to the Americas via one of […]

How will climate change stress the power grid? Hint: Look at dew point temperatures

September 24, 2018

BUFFALO, N.Y. — A new study suggests the power industry is underestimating how climate change could affect the long-term demand for electricity in the United States. The research, published today in the journal Risk Analysis, was led by the University at Buffalo and Purdue University. It describes the limitations of prediction models used by electricity […]
