Answer 2

Answer:

A greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect[1] on planets. The primary greenhouse gases in Earth's atmosphere are water vapor (H

2O), carbon dioxide (CO

2), methane (CH

4), nitrous oxide (N

2O), and ozone (O3). Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F),[2] rather than the present average of 15 °C (59 °F).[3][4][5] The atmospheres of Venus, Mars and Titan also contain greenhouse gases.

Human activities since the beginning of the Industrial Revolution (around 1750) have produced a 45% increase in the atmospheric concentration of carbon dioxide, from 280 ppm in 1750 to 415 ppm in 2019.[6] The last time the atmospheric concentration of carbon dioxide was this high was over 3 million years ago. [7] This increase has occurred despite the uptake of more than half of the emissions by various natural "sinks" involved in the carbon cycle.[8][9] The vast majority of anthropogenic carbon dioxide emissions come from combustion of fossil fuels, principally coal, oil, and natural gas, with additional contributions coming from deforestation, changes in land use, soil erosion and agriculture (including livestock).[10][11] The leading source of anthropogenic methane emissions is animal agriculture, followed by fugitive emissions from gas, oil, coal and other industry, solid waste, wastewater and rice production.[12] Traditional rice cultivation is the second biggest agricultural source of GHG after livestock. Traditional rice production globally accounts for about 1.5% of greenhouse gas emissions, equivalent to all aviation emissions. Its source is methane, created by organic matter decomposing underwater in flooded paddies.[13]
