What is the Greenhouse Effect? How Do Clouds Create Temporary Greenhouse Effects and How Do They Affect our Climate?

Greenhouse effect Infrared heat is trapped in the atmosphere by greenhouse gases. Major GH gases are: Water Vapor: (most abundant GHG) evaporation of water Carbon Dioxide:(most abundant human produced GHG) source= burning of fossil fuels Methane: Source= landfills, live stock emissions

Watch the infrared heat react with the greenhouse gases Watch the infrared heat react with the greenhouse gases

Greenhouse Effect Leads to Global Warming The trapped heat in the atmosphere causes a warming period. Melting of glaciers and poles Sea levels rise on coasts Higher evaporation rates, deserts created in inland regions Crops die off

How Can Clouds Create a Temporary GH effect Create cooler days b/c they block some insolation from entering the atmosphere Warmer nights bc they trap the infrared heat in the atmosphere

Without Clouds Days are warmer b/c most insolation is received. Night temps drop more b/c there are no clouds to keep the infrared heat trapped in the atmosphere
