How does agriculture affect global warming?

Answer 1

We might guess that when crops are plowed, or leaves emit moisture, that the amount of water vapor in the air goes up.

A:Climate scientists, as a group, are in no doubt that average global temperatures are rising, and that human activity is the principal cause of that rise. Farming, including agriculture, is a contributor to the increase in atmospheric carbon dioxide levels that cause enhanced global warming, although not the the extent that burning fossil fuels and cement manufacture are.

Agriculture often leads to removal of forests. Since forests sequester carbon, deforestation releases this carbon into the air as carbon dioxide, adding significantly to atmospheric levels.

Ruminants, such as cattle and sheep, release methane gas when they belch. Since methane is a far more potent greenhouse gas than carbon dioxide, this is another important source of global warming.
