On Friday’s St. Louis on the Air, host Don Marsh was joined by Dr. Peter Raven, the former, longtime president of Missouri Botanical Garden, to discuss environmental issues. Raven recently celebrated his 80th birthday.

Even in his retirement, Raven is staying busy with his work on the board of the National Geographic Society and writing his biography. He is still deeply immersed in the challenges facing the planet today.

In December, government representatives from all over the world will meet in Paris for another conference on climate change aimed at reducing greenhouse gas emissions and curbing rising global temperatures.

In advance of that meeting, some scientists and environmental leaders are gathering at Washington University to discuss one particular consequence of climate change: widespread species extinctions.

Director Emeritus of the Missouri Botanical Garden, Peter Raven, is one of the minds behind the latest papal letter from Pope Francis. He issued the sweeping encyclical Thursday that calls for immediate societal changes to preserve the environment.

People in urban areas may not think about the importance of prairies. But beyond the asphalt, concrete and glass of the city, is a country rich in prairie land.

But, what is the importance of prairies and how do they affect our everyday lives?

On Thursday's “St. Louis on the Air” Peter Raven, president emeritus of the Missouri Botanical Garden, and Rudi Roeslein, CEO of Roeslein Associates, joined host Don Marsh to discuss the role of prairies conserving of natural ecosystems and their importance for production of next-generation biofuels.

This article first appeared in the St. Louis Beacon, Dec. 5, 2012 - WASHINGTON - From historic floods in the Midwest to destructive clusters of tornadoes in the mid-South to drought-related fires sweeping across Texas, the number of officially declared U.S. disasters reached a new record this year.

While those natural disasters in the United States play only a small role in the World Meterological Organization's (WMO) report on extreme weather events in 2011, there is a tendency to try to link the underlying weather patterns to changes in the global climate.

This article first appeared in the St. Louis Beacon, Nov. 15, 2011 - WASHINGTON - When physicist Richard A. Muller reported last month that global temperatures had warmed since the 1950s, his finding was met with a collective yawn among mainstream climate scientists who had reached the same conclusion years before.

But Muller's study made waves in the media because he had been a prominent climate-change skeptic, partly funded by a foundation linked to global-warming deniers, and his research focused on skeptics' objections to previous studies of warming.

Once every three months, Peter Raven pays a visit to his dermatologist. Summers spent at 10,000 feet, hiking northern California's Sierra Nevada Mountains and roaming the sand dunes and vacant lots of San Francisco take their toll. "That did a real number on my skin. Of course, nobody thought a thing about the sun in the 1950s," Raven said, describing a boyhood spent outdoors, rearing butterflies, collecting insects and gathering plants.

Descriptions of Peter Raven's tenure as president of the Missouri Botanical Garden range from superlative to superlative.

"Since he put down roots here in 1971, Dr. Raven has been one of St. Louis' favorite exotics. He is a generous civic leader, consummate showman, wise counsel and world expert on biodiversity. I expect him to continue in all those roles," said St. Louis mayor Francis Slay in a statement to the Beacon.

This article first appeared in the St. Louis Beacon: October 20, 2008 - Most people, including policy makers, spend very few waking moments thinking about science -- much to the consternation of many scientists. A very small number of people are involved in science policy. And the science "establishment" needs to rethink how to connect science and the public, according to Richard Borchelt, communications director for the Genetics and Public Policy Center of the Berman Bioethics Institute at Johns Hopkins University.

This article first appeared in the St. Louis Beacon: Hope, the sole polar bear at the St. Louis Zoo, is set to begin another summer of backstroking, ball-playing and other antics in the protective custody of the zoo’s Bear Bluffs exhibit.

Meanwhile, far to the north, the 20,000 to 25,000 polar bears left in the Arctic wild will continue their precipitous population decline with another year of unusual starvation, drowning and infant mortality – a decline caused by melting sea ice.
