There are three main effects on wetland plants from global warming, each of which will create worsened conditions for them. Flooding, sea level rise, and intense storms all threaten wetland plants but in different ways. Intense storms are expected to overwhelm wetland plants and soils which can "only absorb a certain amount of water" (Global 1). This will lead to the excess flooding into streams and rivers, but less water will be available overall because of flood water lost to the ecosystem. Gaps between storms are expected to increase, so wetlands plants "will experience more drought stress" (Global 1). Rising sea levels from the melting of snow cap, glaciers and sea ice is expected to rise an additional "ten to ninety centimeters" this century (Global 1). This will inundate low-lying areas like Southern California, where the overflow will pour into wetlands causing high levels of nitrate pollution in ground water. Since humans have developed areas inland of natural wetlands, expert predict these organisms and their ecosystems "are in danger" (Global 1). Because the wetlands provide valuable services as ecosystems, the destruction of plant life in them will have a detrimental impact on the economy of California. This impact stems from things like contaminated ground water to loss of plants and wildlife.
