October 04, 2017 Climate Change And Hurricanes
https://earthwiseradio.org/wp-content/uploads/2017/10/EW-10-04-17-Climate-Change-and-Hurricanes.mp3
No single weather event can be attributed to climate change. Storms, floods and droughts have always happened and some of them have always been severe. However, two centuries of people burning fossil fuels has altered temperatures just enough that some of the storms we have seen in recent times have been much worse than they otherwise would have been.

October 03, 2017 The Tiny Country That Feeds The World
https://earthwiseradio.org/wp-content/uploads/2017/10/EW-10-03-17-The-Tiny-Country-that-Feeds-the-World.mp3
The Netherlands is a small, densely populated country with more than 1,300 inhabitants per square mile. It lacks almost every resource one associates with large-scale agriculture. Nevertheless, it is the number two exporter of food in the world, second only to the United States, which is almost 300 times bigger. The Dutch lead the world in exporting tomatoes, potatoes and onions and produce many other crops as well.

October 02, 2017 Measuring Earth’s Outgoing Energy
https://earthwiseradio.org/wp-content/uploads/2017/10/EW-10-02-17-Measuring-Earths-Outgoing-Energy.mp3
The earth’s energy imbalance is the difference between the amount of solar energy absorbed by the earth and the amount of energy the planet radiates back into space as heat. If the imbalance is positive, that is, if more energy is coming in than going out, then the earth will get warmer over time. If the imbalance is negative, then the planet will get cooler.

September 29, 2017 Pine Barrens Threatened
https://earthwiseradio.org/wp-content/uploads/2017/08/EW-09-29-17-Pine-Barrens-Threatened.mp3
Pine barrens occur throughout the northeastern U.S. from New Jersey to Maine. They are plant communities that occur on dry, acidic, infertile soils dominated by grasses, forbs, low shrubs, and small to medium-sized pines. The Pine Bush Preserve in Albany, New York is one of the larger inland pine barrens in the country.

In a trial taking place in Denmark, some electric car owners are earning more than $1,500 a year just by parking their cars and feeding excess power back into the grid.

September 27, 2017 Super Blooms
https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-27-17-Super-Blooms.mp3
This past August one of the driest regions on Earth transformed from a barren desert to a sea of colorful flowers. Heavy rains in Chile’s Atacama Desert caused the phenomenon, locally known as the desierto florido or flowering desert. These things typically only happen every five to seven years, but the previous super bloom actually took place in 2015.

September 26, 2017 Better Zinc-Air Batteries
https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-26-17-Better-Zinc-Air-Batteries.mp3
Zinc-air batteries are metal-air batteries powered by oxidizing zinc with the oxygen from the air. They have high energy densities (as much as five times more energy than lithium-ion batteries) and are more environmentally friendly. Since they are based on abundant zinc, they are potentially much cheaper to produce than the lithium-ion batteries that are used in so many current applications. But because it is difficult and expensive to produce rechargeable versions of these batteries, they have only found limited use in hearing aids, in some film cameras, and in large form to power navigation instruments, oceanographic experiments and railway signals.

September 25, 2017 Air Travel And Global Warming
https://earthwiseradio.org/wp-content/uploads/2017/09/EW-09-25-17-Air-Travel-and-Global-Warming.mp3
Air travel is pretty carbon intensive. For those of us who take plane trips, it represents a substantial part of our individual carbon footprints. It isn’t that plane travel is inefficient fuel-wise on a miles-per-gallon-per-passenger basis compared with driving, for example. It is just that we go so much farther on planes. Currently, aviation accounts for only a few percent of overall carbon emissions, but that is changing for two reasons.

The North Atlantic island of Bermuda is a popular tourist attraction with its pink sand beaches, turquoise water, and pastel-colored cottages with white limestone roofs. The stepped white roofs are not just picturesque, they are highly functional.

September 21, 2017 New Rules For Ocean Conservation
https://earthwiseradio.org/wp-content/uploads/2017/08/EW-09-21-17-New-Rules-for-Ocean-Conservation.mp3
In a recent report to a United Nations ocean conference, scientists are warning that new rules are desperately needed to protect marine life in the open seas. That’s because more than 60% of the ocean has no conservation rules since it’s located outside national jurisdictions. The open ocean is at risk from climate change, over-fishing, deep sea mining, farm pollution, and plastics pollution.
