That’s right a fulgurites found in the Libyan Desert, which is formed when lightning strikes sand, offer insight into ancient climates. That’s because it traps very tiny bubbles of (CO2), carbon monoxide (CO) and nitric oxide (NO) which contain hidden hints of the type of plants that were struck along with the sandy ground some 15,000 years ago.
Rafael Navarro-Gonzalez, a researcher at Mexico City’s Universidad Nacional Autonoma de Mexico i9s quoted to have said:
Up to now no one was interested in doing actual research on them, No one had even attempted to date fulgurites.
All the information from the fulgurites indicates that the Libyan Desert was once a lot less arid than it is today. Time will tell what other secrets the fulgurites hold.
