Answer:
<em>sea-level rise
</em>
<em>increased rainfall
</em>
<em>increased agricultural irrigation
</em>
these three things can increase with various causes
Further Explanation:
Sea-Levels
From 3,000 years ago to the beginning of the 19th century, sea levels almost only increased by 0.1 to 0.2 mm / year; since 1900, sea level rises 1 to 3 mm / year; since 1992 the TOPEX / Poseidon altimetry satellite indicates a sea-level rise of 3 mm/year. This change could be an early sign of the effects of global warming on rising sea levels. Global warming is estimated to have a significant influence on sea-level rise in the 20th century.
Rainfall
Rainfall can increase due to the impact of urban heat islands and in the amount and intensity under urban wind. Global warming is also causing changes in rainfall patterns throughout the world, including the atmosphere of rain in eastern North America and the dry atmosphere in the tropics. Rain is a major component of the water cycle and a major provider of freshwater on the planet. The global average annual rainfall is 990 millimeters (39 inches). Climate grouping systems such as the Köppen climate grouping system use annual average rainfall to help differentiate climatic regions. Antarctica is the driest continent on Earth. In other areas, the rain has also fallen with the content of methane, iron, neon, and sulfuric acid.
Agricultural Irrigation
For agricultural irrigation, what is enhanced is the irrigation network. The purpose of improving the agricultural irrigation network is so that farmers get a supply of water to flow through their fields during the long dry season. This can be done by making reservoirs, making water flow channels from existing spring sources, as well as ways to store other large amounts of water supplies.
