July 03, 2018 Saving Wheat
https://earthwiseradio.org/wp-content/uploads/2018/07/EW-07-03-18-Saving-Wheat.mp3
Rising temperatures, drought, pests and diseases are moving north into the U.S. heartland and are increasingly posing a threat to the wheat crop. An insect called the Hessian fly is reducing crop yields by 10% a year in the Midwest. Average temperatures in the Midwest have risen by 2 degrees since 2000, and periods of time between rainfalls is lengthening. Conditions in some areas of the Midwest are getting to be more like those in the Middle East.

June 29, 2018 Tourism And Greenhouse Gas Emissions
https://earthwiseradio.org/wp-content/uploads/2018/05/EW-06-29-18-Tourism-and-Greenhouse-Gas-Emissions.mp3
Tourism is a significant contributor to global gross domestic product. Furthermore, it is growing at an annual rate of 4%, more than many other economic sectors. There are many places around the world where it is the largest industry. But until recently, there really wasn’t very good information about its carbon footprint.

June 28, 2018 The Fight For Greener Cars
https://earthwiseradio.org/wp-content/uploads/2018/06/EW-06-28-18-The-Fight-for-Greener-Cars.mp3
U.S. automakers have always been reluctant partners in the nation’s efforts to reduce air pollution and improve fuel efficiency. There have been struggles for decades between the carmakers and the government in setting Corporate Average Fuel Economy (or CAFÉ) standards. During the Obama administration, some of the most demanding fuel economy and emissions standards were mandated.

June 27, 2018 V2V And Safer Cars
https://earthwiseradio.org/wp-content/uploads/2018/06/EW-06-27-18-V2V-and-Safer-Cars.mp3
Automated cars are coming, but they face many challenges in sharing the roads with human drivers. The on-board sensors in these cars are very effective in many ways, but they cannot see around corners or see through buses or trucks. They won’t know if six cars ahead, someone has slammed on their breaks leading to a chain-reaction collision. Of course, human drivers have the same problems.

June 26, 2018 Renewable Energy Jobs
https://earthwiseradio.org/wp-content/uploads/2018/05/EW-06-26-18-Renewable-Energy-Jobs.mp3
According to a new report by the International Renewable Energy Agency, more than half a million new jobs were generated by the renewable energy industry last year, an increase of 5.3% when compared with 2016. The total number of people working in the renewables sector – which includes large hydropower facilities – has now exceeded 10 million people worldwide.

June 25, 2018 Cold Weather In A Warming Climate
https://earthwiseradio.org/wp-content/uploads/2018/06/EW-06-25-18-Cold-Weather-In-A-Warming-Climate.mp3
The climate is warming. The average global temperature is going up year after year, bringing about significant changes to weather around the world. But the fact is that these changes don’t always lead to warmer weather. And ordinary variations in local weather can also go in either direction.

June 21, 2018 Geoengineering And Developing Countries
https://earthwiseradio.org/wp-content/uploads/2018/06/EW-06-21-18-Geoengineering-and-Developing-Countries.mp3
There are some mind-boggling schemes being discussed to mitigate the global warming caused by greenhouse gases. These include placing giant mirrors in orbit to reflect sunlight before it reaches Earth and launching millions of tons of sulfur into the stratosphere to simulate the effects of a major volcanic eruption.

June 20, 2018 Climate Change And Temperature Variations
https://earthwiseradio.org/wp-content/uploads/2018/06/EW-06-20-18-Climate-Change-and-Temperature-Variations.mp3
It’s no surprise that not everyone on the planet is equally responsible for the effects of climate change. For instance, the Northern Hemisphere, which is home to 13 of the 15 largest countries by GDP, emits far more greenhouse gases than the Southern Hemisphere does. But the whole planet heats up as a result.

June 19, 2018 An Electric VW Bus
https://earthwiseradio.org/wp-content/uploads/2018/06/EW-06-19-18-An-Electric-VW-Bus.mp3
For baby boomers, the Volkswagen bus was the iconic vehicle of the 1960s counterculture. It was introduced in 1950, was popular among Gen Xers coming of age in the 1980s, and lasted in one form or another until 2013, when the last one was built in Brazil.
