Yale Environment 360 has a really interesting article which describes some of the ways that climate zones are shifting on earth. This has profound implications for agriculture as well as ecosystems because the climate zones (defined by a combination of temperature and precipitation characteristics) determine the kinds of crops you can grow and when you…

Measurements of sea level across the world show rising waters along most ocean coastlines, including the United States. But according to a story by WRLN in Miami, the regular forecasts for high and low tide do not take that rising water into account yet, leading to bigger errors in tide forecasts than would normally be…
