Changes in weather or global averages in sea levels and temperature from year to year are popular tangents for discussion but only useful, albeit as entertaining, as the a local sports talk show. The real news is how improvements in energy generation demanded by the dense urban environment are now responsible for the majority of GHG emission reductions. For example, New York City produced 48.02 million tons from all energy sources to reflect a 19% reduction from 2004 to 2013 in three main categories. The main GHG producers are buildings plus street lighting, transportation of all kinds and GHGs connected to urban wastewater treatment, city landfills, and the removal of solid waste out of the city categorized as fugitive.
Overall, the impact of climate change on the world is about the urbanization of energy. Cities are effective at measuring and then decreasing the emission of greenhouse gases (GHGs) into the atmosphere. The urban focus on energy varies by economic sector and social choice. The choice of fuels that reduce carbon intensity remains economic. However, the lack of choice in controlling external factors is the most problematic. External factors that control the amount of energy needed are population growth by location and the weather in “degree days”, but the distinctions between the energy and its users is diminishing rapidly for the first time in human history. Energy use includes the ability to visualize a set of futures based on fact. In the presentation below is not sophisticated climate science. The elevation above sea level is “a” and the sea level rise or a storm surge is “b” a long list of coastal cities will have sea water as follows:
The political readiness for the advent of a new ocean/human/earth “oneness.” is the most disconcerting due to the “fear itself” effect. The extreme sea level via a vision reveals more than the risks it exhibits the lack of capacity for a public decision making process in a privately held world. The hidden data involves changes in value. The effect can go one of two ways. It can push every investor of every square foot into climate change denial for the lack of any other plan, or it can draw every investor in to a plan with the capacity to confront the paralysis embedded in such projections.
Given these conditions, the demand for an evidence-based, performance measured and outcome driven protocol that can reach from local need to global effect is now an indispensable policy requirement. People can understand basic units for analysis such as building floor area and total population and apply a per unit and per capita analysis to provide a reliable basis for trend and regression analysis. Energy coefficients established during study periods help to determine the change in carbon intensity for each energy source in each sector to yield the percentage that each source contributes to the GHG inventory.
While dense urban cities are the largest producers overall, they offer the best environment for protocol analysis and a comparisons among all other resilience/mitigation measures that may have an impact on global conditions. Three “get started” sources are here:
