“If all the ice melts — and that’ll happening if we keep doing what we’re doing — the oceans come up 75 meters. That’s about 250 feet,” Dennis Bushnell, chief scientist at NASA’s Langley Research Center, told the crowd Friday morning.

“This’ll convert downtown Jacksonville skyscrapers into hazards to navigation,” he said.

Bushnell gave a lecture about the consequences of sea level rise on the First Coast Friday morning at the UNF Adam W. Herbert University Center.

A Jacksonville Museum of Science and History exhibit shows Florida’s springs are changing.

On the third floor of MOSH a series of photos stand in big metal frames. All of them show Florida’s springs. But they’re not just pretty art. The pictures show the waterways before they were in distress and now.

Shannon Blankinship, outreach director for the St. Johns Riverkeeper, says she loves the springs.

It’s been 13 years since Sue the Tyrannosaurus rex was spotted in Gainesville, but the dinosaur is back at the Florida Museum of Natural History — and this time, things are getting interactive.

It’s been 67 million years since Sue the T. rex took her last breath, but this summer’s exhibit at the Florida Museum of Natural History is giving visitors a chance to get up close and personal with the largest Tyrannosaurus rex ever discovered.

Mayor Alvin Brown’s Port Task Force has voted in support of breaching a Putnam County dam as an offset for proposed deepening of the Jacksonville Harbor.

A coalition of Jacksonville business and environmental advocates say removing the dam will flush millions of gallons of fresh water into the St. Johns River each day. They say that would offset environmental damage caused by the proposed dredging of Jacksonville’s port.

Meanwhile, advocates for keeping the dam, and the man-made lake behind it, say it acts as a water filter keeping pollution from flowing downstream.

On the March 2015 edition of WJCT's Policy Matters, host Rick Mullaney speaks with nationally renowned water resource and marine life experts James G. Workman, writer and Deputy Director of the Environmental Defense Fund's Catch Share Design, and Dr. Quint White, Director of Jacksonville University's Marine Science Research Institute.

As the Obama administration opens the door to offshore drilling, the oil industry is promising more jobs and less reliance on foreign oil. Some people who live along the Eastern Seaboard are saying, "no thanks."

Coastal towns and cities in several states are formally opposing offshore drilling and oil exploration.

Tybee Island, Ga., is a short drive across the marsh from the historic city of Savannah. The island is dotted with hotels and tiny vacation cottages for tourists — and for about 3,000 people, it's home.

The state of Florida is the region most susceptible to the effects of global warming in this country, according to scientists. Sea-level rise alone threatens 30 percent of the state’s beaches over the next 85 years.

But you would not know that by talking to officials at the Florida Department of Environmental Protection, the state agency on the front lines of studying and planning for these changes.

For the first time in two decades, Florida officials have scheduled a bear hunting season. It's a response to a rise in bear attacks — but it has some environmentalists upset.

Experts say there's plenty of room for humans and black bears to co-exist, but the smell of food is pulling the animals out of the woods and into neighborhoods.

If you want to understand the situation, take a trip to Franklin County, in the pandhandle. A few months ago, a bear attacked a teenager there while she walked her dog near a convenience store.
