NASA Alerts on Ancient Mega Drought Driven by Climate Cycles

Buzzline

Recent research from Stockholm University, featured in Science Advances, indicates that the significant drought associated with the collapse of the Late Bronze Age, approximately 3,200 years ago, was the result of the convergence of various natural climate cycles rather than a singular phenomenon. Through sophisticated climate modeling that covers the last 8,000 years, experts discovered that both long-term orbital shifts and short-term fluctuations in Atlantic climate exacerbated drought conditions in the Eastern Mediterranean region. These results underscore the potential for natural climate variations to heighten drought risks in the context of ongoing global warming affecting sensitive areas.

00:00Scientists say they've uncovered the climate-perfect storm

00:03behind the collapse of ancient civilizations 3,200 years ago.

00:07A new Stockholm University study found the drought wasn't caused by a single climate event.

00:13Instead, several natural climate cycles aligned, creating an exceptionally severe drought.

00:19Researchers analyzed climate patterns covering the past 8,000 years,

00:23using advanced computer models.

00:25They found Earth's orbit slowly dried the region,

00:28while Atlantic climate shifts made conditions even worse.

00:32The prolonged drought reduced water supplies, damaged agriculture,

00:36and increased pressure on already vulnerable societies.

00:40Major civilizations, including the Mycenaeans, Minoans, and Hittite Empire,

00:45were affected during this period.

00:47Scientists say the findings also matter today,

00:50as the Mediterranean is expected to become hotter and drier.

00:54The study suggests future droughts could become even more severe

00:57when natural climate cycles combine with human-driven warming.
