Climate and Warming Writing about climate change and global warming is politically dangerous, but here goes. There is confusion regarding the difference between global warming and climate change. I saw an hour-long presentation on "climate change" the other day that was really about global warming. That Earth's average temperature is currently higher than in the past relates to global warming and discussions about the natural and anthropogenic causes of that warming. Certainly Earth's warming impacts climate. There is no such thing as a global climate - a phrase frequently used by uninformed people. Earth's climates consists of six types, each with well-defined climate regions. Each climate region is classified by well-known characteristics. As long as those regional characteristics are within the prescribed range the climate does not change. For example, based upon historic data, 130 years ago, Little Rock's climate was classified as Cfa. That has not changed. Little Rock's climate remains a Cfa in 2012.	0	No activity
Local vs. Global I argue that what appear to be local issues are not just local issues, but are global and to remove that element from the discussion is harmful to students. Chemical contamination connected to a refinery explosion in Delaware City which sent toxic gasses into the night sky is not JUST a local issue, but a global issue. The global community shares the air of "night sky." Spraying formaldehyde on eggs and slaughtering 600 million chickens on Maryland's Eastern shore is not JUST a local issue, but a global issue. The water of the Chesapeake goes into the Atlantic and touches other distant shores. Hydrofracturing natural-gas wells is not JUST a local issue, but a global issue. Natural gas produced at home means less reliance on foreign (global) energy and natural gas consumed at home means cleaner air at home and abroad - the air, wind is global. Students need a clear understanding that what takes place locally frequently has global consequences that should not be ignored.	0	No activity
