https://earthwiseradio.org/wp-content/uploads/2018/03/EW-04-23-18-Fewer-Snowbird-Sharks.mp3
Blacktip sharks are snowbirds, to use a cross-species metaphor. At least, they usually are. The males of the species swim south to southern Florida during the coldest months of the year and head back north to North Carolina in the spring to mate with females.

April 20, 2018 Elephant Losses Imperil Forests
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-04-20-18-Elephant-Losses-Imperil-Forests.mp3
Poaching and habitat loss have reduced Central African elephant populations by 63% since 2001. These losses not only pose dire consequences for the elephants themselves but also for the forests in which they live.

April 19, 2018 Climate Change And Biodiversity
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-04-19-18-Climate-Change-and-Biodiversity.mp3
According to a new study recently published in the journal Climatic Change, up to half of the plant and animal species in the world’s most naturally-rich areas could face local extinction by the turn of the century due to climate change. This projection, jeopardizing the biodiversity in places like the Amazon and the Galapagos, assumes carbon emissions continue to rise unchecked.

April 17, 2018 Using Rye To Grow Edamame
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-04-17-18-Using-Rye-to-Grow-Edamame.mp3
Herbicide-resistant weeds are becoming a more and more common problem for farmers growing grain and vegetable crops. As a result, the farmers are looking for alternatives to herbicides to control weeds. One promising approach is the use of cover crops, which are planted in the off season to protect the soil. Thick cover crop growth can often compete well with weeds during the cover crop growth period, and can prevent most germinated weed seeds from completing their life cycle and reproducing.

April 16, 2018 Cooling Cities With White Roofs
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-04-16-18-Cooling-Cities-with-White-Roofs.mp3
The phenomenon of urban heat islands has been well known since the 19th century. The materials from which city buildings and roads are made reflect much less solar radiation and absorb more of it than the vegetation they have replaced. The absorbed energy is then radiated in the form of heat into the surrounding air making cities warmer.

April 13, 2018 FEMA And Climate Change
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-04-13-18-FEMA-and-Climate-Change.mp3
In 2017, the United States spent a record $306 billion on weather and climate-related disasters, making it the costliest and most damaging year on record. The wildfires out west, Hurricanes Irma, Maria, and Harvey, the Minnesota hailstorm, and the midwest drought are just some of the costly examples. Officials say that already-bloated figure will increase further in the coming years as temperatures rise.

April 12, 2018 Air Pollution Reducing Global Warming
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-04-12-18-Air-Pollution-Reducing-Global-Warming.mp3
Pollution particles emitted by diesel cars and trucks, coal-fired power plants, factories, primitive cook stoves, and the burning of forests are major contributors to the pervasive air pollution that plagues many cities and regions of the world. In India and China, such pollution leads to hundreds of thousands of deaths each year. And countries around the world are working hard to reduce pollution.

April 11, 2018 Upgrading The Doomsday Seed Vault
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-04-11-18-Upgrading-the-Doomsday-Vault.mp3
The Svalbard Global Seed Vault, located nearly 400 feet beneath the earth’s surface and fully funded by the Norwegian government, offers any government access to seeds in case of natural or man-made disaster. It’s more often referred to as the Doomsday Seed Vault. And ironically, it too is threatened by climate change.

April 10, 2018 The Chinese War On Pollution
https://earthwiseradio.org/wp-content/uploads/2018/03/EW-04-10-18-The-Chinese-War-on-Pollution.mp3
For years, China has been struggling with some of the worst air pollution in the world. According to the European Union, only 1% of the country’s half a billion city dwellers were considered safe because almost all of its major cities were covered with what was described as a toxic grey cloud.

April 09, 2018 Spring Is Springing Earlier
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-04-09-18-Spring-is-Springing-Earlier.mp3
A comprehensive study has confirmed what has been widely believed in the scientific community and in popular reports for years: spring is arriving earlier and the further north you go, the more pronounced is the effect.
