Computer model used to pinpoint prime materials for efficient carbon capture
When power plants begin capturing their carbon emissions to reduce greenhouse gases – and to most in the electric power industry, it's a question of when, not if – it will be an expensive undertaking.

Research: Negative leakage could be key to reducing carbon emissions
(Phys.org) -- The unilateral efforts of a single country or region to reduce the emissions of greenhouse gases could reduce exports, increase imports and lead to higher emissions elsewhere – what economists call “leakage.” ...

Oxygen-separation membranes could aid in CO2 reduction
It may seem counterintuitive, but one way to reduce carbon dioxide emissions to the atmosphere may be to produce pure carbon dioxide in powerplants that burn fossil fuels. In this way, greenhouse gases — once isolated ...

Researchers plan to double biofuel yield from a non-food oil seed crop
One of the most promising avenues for reducing our national dependence on imported oil, lowering greenhouse gases and boosting domestic fuel production is biofuel from non-food plant seed oils. Recently, a University of Massachusetts ...

A NASA weather 'Eye in the Sky' marks 10 years
For 10 years, it has silently swooped through space in its orbital perch 438 miles (705 kilometers) above Earth, its nearly 2,400 spectral "eyes" peering into Earth's atmosphere, watching. But there's nothing ...

Greenhouse gas
Greenhouse gases are gases in an atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. Common greenhouse gases in the Earth's atmosphere include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In our solar system, the atmospheres of Venus, Mars and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would be on average about 33°C (59°F) colder than at present.
Human activities since the start of the industrial era around 1750 have increased the levels of greenhouse gases in the atmosphere. The 2007 assessment report compiled by the IPCC observed that "changes in atmospheric concentrations of greenhouse gases and aerosols, land cover and solar radiation alter the energy balance of the climate system", and concluded that "increases in anthropogenic greenhouse gas concentrations is very likely to have caused most of the increases in global average temperatures since the mid-20th century".
