Study questions about global warming.
(33) List some processes that may feedback to amplify (or decrease) the warming due to gi gases? Which are/is most important? Which are most uncertain? (34) Explain the meaning of the basic feedback parameter (35) Which type of clouds are likely to exert stronger influence on surface temperatures: high clouds or low clouds? Why the difference? (36) Climate feedback parameter is an "emergent" property of a climate model (e.g. GCM). It is not coded, but can be calculated by doing certain types of runs with the model. Explain what sort runs you need to carry out with a climate model to determine the climate feedback parameter of the model? (37) Further to (36), what sort of additional runs are needed to separate this feedback parameter into the various contributions from water-vapor, cloud and ice-albedo feedbacks (al 120, dekud, ce).Explanation / Answer
SOLUTION;-33.
The warming of Earth's surface and lower atmosphere due to the presence of certain gases in the air is known as the greenhouse effect. The gases involved are collectively termed greenhouse gases; the most significant of these are water vapor, carbon dioxide, methane, and nitrous oxide. The greenhouse effect is so named because it resembles the warming of a botanical greenhouse, but the comparison is not a perfect one. On the regional scale or the global scale whenever there is an increase in these gases this results in the temperature rise throughout the globe. The best way to remove/reduce CO2 is to plant more trees and work on producing less of it. IE: Cleaner energy technology.
Secondly - CO2 isn't the only greenhouse gas - There's also water vapor, methane and a few other more minor contributors. But the big three are Water Vapor, Methane and CO2. There are also geo-engineering solutions such as CO2 scrubbing. We can plant more trees and/or reduce the deforestation of rain forests. The problem here is not technological, it is economic
