A Major Scientific Climate Change
The Saudi Heritage Commission has just shared a discovery that changes how we view Saudi Arabia’s past. A new study published in the journal Nature, on climate change reveals that the Arabian Peninsula was once a lush, green region filled with rivers, lakes, plants, and animals.
This research is part of the Green Arabia Project, a long-term effort to understand how the Kingdom’s climate and environment have changed over millions of years.
Climate Change: Where It Was Found
The discovery was made in Duhool Al-Sammar, a group of caves located in the Summan sinkholes in eastern Saudi Arabia. These caves held layers of mineral deposits that recorded past weather patterns — similar to how tree rings or ice cores can show past climate data.
Researchers studied stalactites and stalagmites inside the caves, which revealed evidence of repeated wet and rainy periods going back as far as 8 million years. These wet phases were long enough to turn what is now desert into green spaces filled with life.
What the Climate Change Study Found
The study shows that Saudi Arabia was not always dry and desert-like. In fact, during several periods in the past, it was humid, fertile, and full of water sources. These conditions allowed plants to grow and supported many animals — even species like crocodiles and hippos, which need water-rich environments.
These fertile periods happened more than once, meaning the climate kept changing over time. Each wet phase allowed life to spread across the region again causing a climate change.
A Natural Bridge Between Continents
One of the most important results of the study is the discovery that Saudi Arabia acted as a natural land bridge between Africa, Asia, and Europe. During these green phases, both animals and early humans were able to travel across the Peninsula.
This makes the Arabian Peninsula a key location in the history of early human migration. It also helps researchers understand how people and animals moved from one part of the world to another.
A Team Effort With Global Partners
The study was led by the Saudi Heritage Commission and involved a team of 30 researchers from 27 institutions, both inside and outside Saudi Arabia. This collaboration made it possible to confirm earlier fossil discoveries and to create the longest-known climate record for the region.
This type of research not only improves global understanding of ancient climate changes, but also helps highlight Saudi Arabia’s role in world history and science.
These findings are not just interesting facts from the past — they support Saudi Arabia’s Vision 2030, which includes goals to protect national heritage, promote tourism, and encourage scientific research.
By revealing that the Kingdom was once full of life and greenery, this discovery strengthens Saudi Arabia’s position as a place of deep and important history. It also opens the door for more research, tourism, and education around the country’s natural and cultural heritage.
