TAMPA, Fla. — An unknown suspect targeted a South Tampa yard sale, benefiting a good cause, with phony money. Katherine, who asked us not to share her full name, was hosting a fundraiser Saturday for her teenage niece, who is in need of a new kidney. "I love her and we did this as an effort to raise money for her so she can get the transplant and it would be less money out of her family’s pocket," said Katherine. Katherine says one man came by the yard sale and talked her down in price for a pair of designer purses and an original painting from Haiti, where she was previously deployed in the military. Turns out, a bill was bogus, handed to her in a peculiar way as to not reveal that it was counterfeit. 730

Summer is in full swing, and with the warmer months comes the mosquitoes. Not only are the small insects pesky, they are considered the deadliest animal in the world, believe it or not. More than 700 million people around the globe get sick from mosquito bites, and more than 700,000 people die from those bites each year."We always see West Nile Virus peaks right after the Fourth of July weekend, because people have been outside and not protecting themselves," says Kylee Grenis, an expert on mosquitoes. Grenis helped us conduct an experiment to find out which bug repellent works the best.We purchased three mosquito traps. We sprayed one trap with DEET. The other with a top rated non-DEET spray called Skin So Soft by Avon. The third trap was a controlled trap with no spray.The traps were hung next to dry ice in a mosquito-infested park."We are going to hang some dry ice near those traps to simulate a human standing and breathing and hopefully that will help attract more mosquitoes to our traps," explains Grenis on the use of dry ice. After an hour, the trap sprayed with DEET had one mosquito. In the Avon-sprayed trap, there were no mosquitos. In the control trap, there were six mosquitos. The sprays kept the mosquitos away.As far as sprays go, Grenis says she still prefers DEET. "It is great at making you invisible to mosquitoes,” she says. “That blocks the receptors so that they can't detect your carbon dioxide signature." But, many consumers fear products with DEET are not safe. "I think a lot of the time people get it confused with DDT,” she explains of Dichlorodiphenyltrichloroethane (DDT), a chemical compound banned in many countries due to the danger it poses to wildlife and the environment.DEET is safe to use and just like the Avon spray, and both sprays are effective in keeping mosquitos away during the summer time months. 1872

Rick Brown walks through Kenai Fjords National Park to a place where climate change's impact is hard to miss. “The changes to us have been bang, bang, bang," Brown says. "Every year it’s a different year."As the years have gone on, the walk to Exit Glacier has become longer because it's melting away. Exit Glacier is one of the smaller glaciers in the park. It's popular with tourists because it's easy to get to. It's a short walk from where they park. Signs mark the path people take to get to the glacier; the dates on the signs range from the early 1900s to 2010. The signs mark where the glacier once was and where it's melted to. "If this doesn’t convince you that things are changing, then there is no use in trying to even convince you," Brown says.Brown owns Adventure 60 North. He takes people on tours and hikes around the glacier. It's a job in glacier tourism that often has him facing questions about climate change. "I tell them what I see, I don’t know the reason why it’s happening," he says. His answer isn't about politics but what's become the reality here."I don’t know if it's humans or nature or naturally caused. I think it’s both, and that's my opinion and I kind of leave it at that," Brown says."I've lived in Alaska for almost 50 years. Anyone who has lived here a long time has seen the weather change," says Doug Capra.Capra is a former park ranger and local historian in tiny Seward, Alaska. “We’ve seen winters come later, springs come earlier,” Capra says. For years, he's documented Alaska's changing climate and Exit Glacier's retreat.“My concern is the denial. I write history and I have great admiration for human ingenuity," Capra says. "Human beings have survived a lot of things. It’s the questions of how we’re going to do it. It’s a question of will."Rick knows some people can't be convinced of the impact climate change is having.“Some people come here with a view that they’ve adopted and they’re not going to change no matter what you tell them," Brown says. "So I don’t try. I’m the old guy out here, I know what I'm seeing."He says winters don't see the snow they did when he first became a guide in Alaska in the '90s. He no longer does snowshoeing and ice hiking tours in the winter because of the lack of snow.“It’s changed our business," he says. "I don’t know if it’s hurt it. I would say we’ve adapted. And as far as I know, the key to surviving here is adapting."Time may be running out for Exit Glacier. “I would say, probably, I don’t know ... there have been guesses of ten, five years?” he says.According to the United States Geological Survey, 68.7% earth's freshwater is kept in ice caps and glaciers, meaning their retreat isn't just an Alaskan concern or one Brown feels should be left for the future. "It's real folks," Brown says. "Change is happening. Regardless of what’s causing it. We need to get prepared to adapt to deal with the change." 2922
