May 11, 2018 Extreme Weather Increasing
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-05-11-18-Extreme-Weather-Increasing.mp3
It sure seems like extreme weather is increasingly common: floods, droughts, extreme rainfall, powerful snowstorms, hurricanes and so on. But we tend to focus on recent events and often give them undue emphasis. So, it is reasonable to ask whether extreme weather really is more common these days.

The Great Pacific Garbage Patch is the world’s largest collection of floating trash. It lies between California and Hawaii and is popularly described as being larger than Texas. It was discovered in 1997 by a yachtsman who sailed through a mess of floating plastic bottles and other debris while on a voyage between Hawaii and Los Angeles.

May 08, 2018 Greenhouse Gas Emissions Rising Again
https://earthwiseradio.org/wp-content/uploads/2018/04/EW-05-08-18-Greenhouse-Gas-Emissions-Rising-Again.mp3
If we want to avoid drastic global warming this century, we need to sharply reduce greenhouse gas emissions over time. For the previous three years, emissions had been holding steady, but last year, global emissions from the use of coal, oil and natural gas increased by 1.4%. According to the International Energy Agency, this unfortunate new data should serve as a strong warning that we need to increase our efforts to combat climate change.
