Tourists spend thousands of dollars to explore and enjoy Guatemala's lush and thriving rain forests. It's hard to believe that the landscape was different, but according to new research by climate scientists at the University of Nevada Las Vegas (United States), those places were probably very different less than 9,000 years ago, which is a “blink of an eye. eyes ”from the point of view of geological standards.

It's hard to believe the landscape ever looked any different. But according to new research by UNLV climate scientists, the locations where those jungles exist today likely looked very different less than 9,000 years ago -- a blink of an eye by geologic standards.

To go big, sometimes you have to start small.

UNLV researchers have been awarded a $700,000 grant to bring a new technology to campus that will enable researchers to study stalagmites in Nevada’s Great Basin National Park, volcanoes in Hawaii and even rocks from Mars.

There’s a question out there related to climate change that everyone asks but no one seems to have a good answer for: When will climate change reach the point of no return? Read the news, and timelines range from 18 months to 12 years to 40 years. UNLV geology professor Matt Lachniet explained it is not about an exact drop-dead moment.

When Americans celebrated the first Earth Day on April 22, 1970, the planet's atmosphere was markedly different than it is today. Nearly 50 years ago, scientists measured Earth's levels of carbon dioxide — the planet's most important greenhouse gas — at around 325 parts per million, or ppm.

Forty-two centuries ago, the flourishing Akkadian Empire—spread across modern-day Iraq, Turkey, and Syria—suddenly disappeared. Paleoclimatologists and other geoscientists now have one possible explanation for why. Using precisely age dated chemical measurements from a stalagmite collected in a cave in Iran, researchers found an abrupt uptick in dust at that point in history. This heightened dust activity, which persisted for 300 years, might have made for uncomfortable living conditions and difficulties in farming, the researchers suggest.
