Peter Langdon Ward by the Montreal Protocol on Substances that Deplete the Ozone Layer led to the Global Warming Hiatus from 1998 to 2013, during which no statistically significant warming occurred. Warming began again in August 2014 when Bárðarbunga volcano in Central Iceland erupted 85 square kilometers of basaltic lava in six months—the largest effusive volcanic eruption since 1783. As with most effusive volcanic eruptions, this one did not form cooling aerosols in the stratosphere. All of this research is explained in detail at WhyClimateChanges.com, is summarized in a book aimed primarily at non-scientists, What Really Causes Global Warming? Greenhouse Gases or Ozone
Separation of concerns 1989, Chris Reade wrote a book titled "Elements of Functional Programming" that describes separation of concerns: Reade continues to say, Separation of concerns is crucial to the design of the Internet. In the Internet Protocol Suite, great efforts have been made to separate concerns into well-defined layers. This allows protocol designers to focus on the concerns in one layer, and ignore the other layers. The Application Layer protocol SMTP, for example, is concerned about all the details of conducting an email session over a reliable transport service (usually TCP), but not in the least concerned about how the transport service
