Climate researcher shines in Cleveland, perfect place to study the Anthropocene

Marc Lefkowitz  |  04/30/18 @ 10:00am  |  Posted in Climate, Transform

Case assistant professor of biology, Dr. Sarah Diamond, was thrust into the limelight last year when her work on a tiny harbinger of climate change, the acorn ant, was covered in the New York Times article, What Makes a City Ant? Maybe Just 100 Years of Evolution. The George B. Mayer Chair in Urban and Environmental Studies summarized her work...

Cities that think like planets: An urban ecology framework for Cleveland

“I suggest that most post-industrial cities are hybrid and unstable,” urban ecologist Marina Alberti states in her book, Cities That Think Like Planets. “We can drive them to ecological collapse.” A professor of urban design and planning and director of the Urban Ecology Research Lab at the University of Washington, Alberti explains how cities avoid such a fate and instead build...

The long view: How University Circle flood became an issue of regional concern

Sunday's rains flooded out parts of Cleveland—cars were seen literally floating along Euclid Avenue, that is, if they could reach University Circle at all with multiple road closures causing a Monday morning ruckus. By Tuesday, the area dodged another episode as rain turned to snow. Before the next spring torrent arrives, let’s talk about what extreme weather events like this...

Urban patterns have complex impacts on variables that change slowly in response to long-term processes (e.g. mitigating floods) and that constrain the response of fast variables (e.g. land cover change), generating a shift in the hydrological regime.

It's time for a new story about climate change

Marc Lefkowitz  |  02/19/18 @ 10:00am  |  Posted in Climate, Transform

“Tell a new story about climate change.” This line captures the key take away for me and, hopefully, the fifteen public-facing staffers at The Cleveland Museum of Natural History who spent a full day immersed in a workshop for the National Network for Ocean and Climate Change Interpretation (NNOCCI). NNOCCI has meticulously crafted and has been sharing a new story about...

When climate change is natural and when it very clearly is not

Marc Lefkowitz  |  12/06/17 @ 12:00pm  |  Posted in Climate

Timing is everything, and that includes climate change. For 65 million years, the climate has experienced natural changes—as the earth tilted a little on its axis and its orbit stretched, the sun’s energy reaching earth was diminished to the extent that it triggered an Ice Age. A mile-high glacier covered where Cleveland is. Florida’s coast line grew to double its...
