How quickly would we see the effects of changing greenhouse gas emissions?

How Harmful Are the Average American’s Greenhouse Gas Emissions?

It has sometimes been claimed (usually without evidence) that the harm caused by an individual’s participation in a greenhouse-gas-intensive economy is negligible. Using data from several contemporary sources, this paper attempts to estimate the harm done by an average American. This estimate is crude, and further refinements are surely needed. But the upshot is that the average American is res...

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

If Emissions of Greenhouse Gases are Reduced, How Quickly do Their Concentrations in the Atmosphere Decrease?

The adjustment of greenhouse gas concentrations in the atmosphere to reductions in emissions depends on the chemical and physical processes that remove each gas from the atmosphere. Concentrations of some greenhouse gases decrease almost immediately in response to emission reduction, while others can actually continue to increase for centuries even with reduced emissions. The concentration of a...

The Economic Effects of Legislation to Reduce Greenhouse-Gas Emissions

The effects of local pollution regulation on greenhouse gas emissions

In most countries, environmental regulation has focused on local pollution, which causes damages near the emission source, while national regulation on greenhouse gases (GHG) has been slow. In this paper, we ask whether US local air pollution regulations have had an effect on GHG emissions. On the one hand, a firm required to lower emissions of local pollutants might respond by adopting technol...
