Northern Guatemala – Climate and Maya Civilization

Boat ride to Guatemala

   Gregg, Brooks, and I crossed into Guatemala from Mexico by riding in a small boat across the Usumacinta River. Although this region is sparsely populated, I noticed an immediate change in the people across the border. The children, instead of asking me how much my bike was worth (as nearly every person in Chiapas asked), smiled, played with my bike seat, and tried to say ‘how are you’ in English. The police told me no one had been attacked on the road in three years, and I rode the dirt road until I found a small town where locals allowed me to camp. Gregg and Brooks continued by van, and we split ways.

We have arrived in Guatemala!

   Thinly populated, northern Guatemala is mostly flat and is covered by thick rainforest except for places cleared for crops or cattle. Riding a day and a half, I arrived at the ruins of Tikal, a city that was once one of the largest and most important cities of the ancient Maya. The Mayan civilization thrived from a few centuries before Christ until around 900 AD, when the civilization collapsed, and nearly all cities across the peninsula were abandoned. Now the impressive stone pyramids and palaces are covered by jungle and tourists.

   The Tikal ruins sit near the large lake of Peten-Itza, and I stayed in a hotel overlooking this lake for $5 a night while nursing a small cold. Here I met with a group of researchers who are drilling into the lake’s bottom, attempting to determine the past climate of the region. By looking at the composition of layers of sediment on the lake’s bottom, the scientists can determine past rainfall patterns and temperature, as well as the type of vegetation that surrounded the lake.

    According to their research, around 900AD, when the Mayan civilization collapsed, a series of intense droughts struck the region, likely making it difficult for the Mayans to feed their large cities. The lake sediments also suggest major deforestation of the region, and it is possible that a combination of drought and land degradation led the Mayans to abandon their settlements. We cannot be sure of how the Mayan civilization collapsed, but it now seems that climate change helped end one of the greatest ancient civilizations of the new world.

    The core drilling projects are fascinating to study—a glimpse into those who have gone before.

    I am 60 years old and even in that short (geologically) time period I have witnessed massive climate change here in Nova Scotia. The winters are many degrees warmer than they used to be as are the summers. Snowfall is perhaps half what it was when I was a child.

    Perhaps eventually we will roast our civiilzations unto death rather than starving them of water.
