Coming out of the last glacial period, there was a sudden climate reversal observed throughout the tropical and subtropical regions of the Earth. The cause of these changes during this interval so enigmatic, so much so, the interval was informally referred to as the “Mystery Interval.” Many large shifts in climates in the past seem to be synchronized with climate in the poles as expressed in ice core records.

The effects of global climate change are being felt in the West’s continuing drought, according to a panel discussion at UNLV last week. Wildfires have increased over the last several years, something one of Colby Pelligrino’s mentors told her years ago would show that climate change is legitimate.

A thaw is underway in Russia, and it has nothing to do with presidential politics. Inside a cave in Russia's Ural Mountains, where Europe and Asia meet, a team of UNLV researchers has found evidence of steady warming since the end of the last ice age.

Global warming has been going on for thousands of years. That’s from a new academic article by a team that includes UNLV geoscientists, one of whom spent months in Russia gathering rare stalagmite samples that were later tested in a lab.

Maybe you've heard about the permafrost that is proving not so permanent in the world's colder places.

On a trip to Great Basin National Park, UNLV geoscience professor Matt Lachniet says that rainfall many millennia ago formed lakes in the desolate basins lining this strip of rural highway. Between the towns of Pioche and Panaca, we stop at Cathedral Gorge, where a multimillion-year dance of erosion and tectonics forged a slender canyon fringed with clay-colored spires.

Understanding the world as it was 5,000 years ago just may provide some answers about the world today.
