  • List Of Greenhouse Gases - WorldAtlas

    IntroductionSafetyUsesPropertiesOzone presents itself in two forms, stratospheric and tropospheric. Stratospheric ozone occurs naturally. Tropospheric ozone, however, is a greenhouse gas that contributes to climate change. Humans produce this gas through industrial plants, chemical solvents, and burning fossil fuels. Prior to industrialization, tropospheric ozone was concentrated at 25 parts per billion in the atmosphere. Today, it is at approximately 34 parts. When O3 mixes with carbon monoxide, the combination results in smog. Taking public transportation, avoiding pesticides, and buying natural cleaning products are all ways to reduce ozone production. Nitrogen trifluoride is produced by industrial gas and chemical companies. It is recognized by the Kyoto Protocol as a greenhouse gas that contributes to global climate change. It has an atmospheric life of between 550 and 740 years. Under this environmental treaty, member countries have committed to reducing emissions of this gas.

    WhatLeft from Scrum and Xp?SafeLessDadLeadingAgileAlternatives to The ‘Big’ FrameworksWhat The Scaling Frameworks Are MissingTeams execute a project at a time (at least, we hope they do). Organizations execute programs – combinations of several projects that may overlap. Larger projects are built by teams of teams, or teams of teams of teams, that may work in different physical locations. This type of work requires coordination. Larger organizations typically want a loose-tight coupling – giving the teams freedom to innovate while creating just enough shared expectations to make cross-team coordination easier. Managing the work-in-progress, the planned work and the scheduling of when projects start and stop becomes much more complex.
