√70以上 greenhouse gas emissions 236823-Greenhouse gas emissions definition
Graph by NOAA Climategov based on data from NOAA ESRL According to the 19 AGGI report, the combined heating influence of the longlived, humanproduced greenhouse gases is 314 Watts for every square meter of Earth's surface Just over 80 percent of that is due to carbon dioxide (66%) and methane (16%)Main Greenhouse Gases Multiple gases contribute to the greenhouse effect that sets Earth's temperature over geologic time Small changes in the atmospheric concentration of these gases can lead to changes in temperature that make the difference between ice ages when mastodons roamed the Earth, and the sweltering heat in which the dinosaurs lived Globally, the primary sources of greenhouse gas emissions are electricity and heat (31%), agriculture (11%), transportation (15%), forestry (6%) and manufacturing (12%) Energy production of all types accounts for 72 percent of all emissions Saudi Arabia Greenhouse Gas Emissions Have Increased By 225 Since 1990 Climate Scorecard Greenhouse gas
