The Local Impact of Climate Change

WFYI — Climate change is directly impacting Indiana farms. The growing season in Indiana is getting harder to evaluate. The data, going in some cases back to 1895, show clear trends, and there are no signs of them stopping or reversing. Indiana will continue to warm, more precipitation will fall, and extremely hot days will be common in many parts of the state. Prof. Matthew Huber, of Purdue EAPS and the director of the Purdue Institute for a Sustainable Future, discusses the local impacts of climate change.

Mystery Hole Found on Mars Could Be Future Astronaut Home

NEWSWEEK — A mysterious pit on Mars, captured by NASA's Mars Reconnaissance Orbiter (MRO), has reignited interest in the potential of these features to support future human missions to the Red Planet. Prof. Brandon Johnson, of Purdue EAPS, discusses this mysterious Martian hole.

What lies beneath: Mars’ subsurface ice could be a key to sustaining future habitats on other planets

PURDUE NEWS — To survive on other planets, water is, of course, critical. We need it to drink, sustain crops and even create rocket fuel. But on spaceflights, checked luggage is exorbitantly expensive. Anything heavy, especially liquids like water, is bulky and costly to haul by rocket, even to our closest interplanetary neighbors. The best plan, then, is to find water at the spacecraft’s destination. Purdue University planetary scientist Ali Bramson’s research is laying the foundation for future extraterrestrial exploration. She is focused on finding ice deposits beneath the barren surfaces of the moon and Mars, providing a buried resource important for future human habitats and even space travel itself. Subsurface ice also is a compelling target for astrobiology, climatology and geology research.

Hurricane forecast points to a dangerous 2024 Atlantic season, with La Niña and a persistently warm ocean teaming up to power fierce storms

THE CONVERSATION — If the National Hurricane Center’s early forecast is right, the North Atlantic could see 17 to 25 named storms, eight to 13 hurricanes, and four to seven major hurricanes by the end of November. That’s the highest number of named storms in any NOAA preseason forecast. Jhordanne Jones, NOAA Climate and Global Change Postdoctoral Fellow with Purdue EAPS, wrote about these predictions in The Conversation.

Satellites and space junk burning up in the atmosphere is a new kind of pollution

CBC — Scientists doing high-altitude sampling of material deposited when meteorites burn up in the atmosphere are seeing a shift in the material they've been collecting. In a recent study in the journal PNAS, scientists found that increasingly the particles contain material that could have only come from vaporized space junk, such as the upper stages of rocket boosters and re-entering satellites. Daniel Cziczo, an atmospheric scientist at Purdue University, said they're now trying to find out what kind of impact this in material in the stratosphere may have on things like the ozone layer and global warming. He is interviewed on Quirks and Quarks radio by CBC.
