Formation and Environmental Changes
Formed over several million years ago through the joining of inland streams, the Mobile-Tensaw Delta has undergone significant environmental changes due to rising global temperatures and shifting sea levels.
The delta valley began its formation as inland streams converged, and around 18,000 years ago, lower water levels in the Gulf of Mexico positioned Alabama's coastline further south. However, rising global temperatures and melting glaciers have led to a rise in sea levels, causing the drowning of the southernmost areas of the delta.
Present-day Mobile Bay reflects this as a submerged section of an ancient river valley. Additionally, the ongoing rise in the water level of the Gulf of Mexico continues to impact the delta.
These changes emphasize the impact of climate change on the Mobile-Tensaw Delta's landscape and highlight the urgency of conservation efforts to protect this natural treasure from further environmental harm.
