Final answer:
Reinforcing coastlines and wetlands, as well as shifting to renewable energy programs, can be added to a national climate plan to protect communities from sea level rise.
Step-by-step explanation:
Rising sea levels due to climate change pose a threat to coastal communities. Adding wetlands can provide natural protection against storm surges and flooding. Reinforcing coastlines and wetlands in a national climate plan can help protect communities from sea level rise. This adaptation strategy is already gaining use as it filters water and protects coastal lands from storms and floods, as well as provides natural habitat for various species.
Another option that can be added to a national climate plan is shifting to renewable energy programs. By reducing reliance on fossil fuels, which contribute to greenhouse gas emissions and climate change, the plan can help mitigate the factors causing rising sea levels and other climate-induced issues.
