The heat caused by infrared radiation is absorbed by greenhouse gases such as carbon dioxide, which slow its escape from the atmosphere.Although greenhouse gases make up only about I percent of the Earth's atmosphere, they regulate our climate by trapping heat in a kind of warm-air blanket ...
Greenhouse gases (GHGs) make up a tiny proportion of today’s atmosphere but make life on earth possible. In their absence, the light absorbed by the earth’s surface and re-emitted as long-wave radiation (heat) would be immediately lost to space. Instead, a substantial fraction of the 16...

The company has just opened up its latest plant in Iceland, and hopes to literally suck greenhouses gases out of the air. Today, we’ll examine whether or not this technology is a viable tool in the fight against climate change. Continue reading “Carbon Sequestration As A Service Doesn’t...
(4) greenhouse gases absorb only a small part of the radiation emitted by Earth, (5) they can only reradiate what they absorb, (6) they do not reradiate in every direction as assumed, (7) they make up only a tiny part of the gases in the atmosphere, and (8) they have been ...
Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap...
a third major announcement has followed in as many weeks; the agreement of an addendum to the Montreal Protocol(agreed in 1987 to progressively eliminate the use of chlorinated fluorocarbons or CFCs, coming into force in 1989)which will bring the HFC family of gases into that process, leading...
Changes in long-lived, well mixed greenhouse gases, such as CO2, CH4, N2O, and halogenated compounds such as CFCs make up the largest and most certain component of radiative forcing, because their concentrations and atmospheric growth rates can be accurately measured in the atmosphere. The effects...
Greenhouse Gas: ↑ A gas in the atmosphere that traps heat, causing higher temperatures. This effect of greenhouse gases is called the greenhouse effect. 温室气体:是指一种在大气中起保温作用的气体,它会使大气的温度升高,这种由温室气体所带来的大气温度的升高被称为温室效应 ...
The companies, Valero Energy Corp. and Tesoro Corp., own refineries in California that would be forced under the law to slash emissions of heat-trapping greenhouse gases. But neither Valero or Tesoro is owning up to it. A Tesoro spokesman did not respond to inquiries. But the company’s we...
