Cloud Seeding for Weather Modification

There is a debate over whether cloud seeding is an efficient way to produce more snow and rain in places where droughts are the worst. Opponents claim that the chemicals that are sprayed into the air to create more water are toxic and could cause health issues in the future. Others believe this is the only way to for some gas and electric companies to obtain more energy. Listen to learn about the other concerns at hand and if this the history of this process.

Clearing Carbon From Our Air

Carbon exists in all living things, including proteins, DNA, and fats. When living things exhale, the result is carbon dioxide. As our world develops, we produce more carbon dioxide with the burning of fossil fuels and the use of cars, trains, and planes. This gas is causing an imbalance in the atmosphere which affects the warming of the planet. Listen to hear how much carbon dioxide humans are responsible for and the effects of global warming.

Biomimicry and a Desert Beetle

To copy the way a desert beetle gets water, scientists have designed a membrane that can extract water from the air. Since all air contains water, even in the desert, this could provide a very inexpensive way to supply drinking water. This process is called “biomimicry,” or using ideas from nature to solve technological problems. This discovery could lead to reusable water bottles that refill themselves. Listen to learn why this invention would be inexpensive and how close scientists are coming to making it work.

Human Impact on Climate Change

A United Nations report in 2014 shows that human activities are changing the planet. The scientists are more confident in their conclusions that humans are causing global warming. There are rising sea levels, higher temperatures and impacts on wildlife. This conversation with a public radio reporter looks at the long term trend in global temperatures and what humans can do to reverse the trend.

Extreme Rains and Global Warming

Scientists are using computer computations to link cases of extreme weather to global warming. Scientists set out to link major flooding in England and Wales in the fall of 2000 to climate change. This task was undertaken by scientists and citizens alike - running thousands of computer simulations and comparing the result in a world with climate change and one without it. Listen to learn what these simulations found.
