Another person died in flooding in Yamparáez where rivers overflowed on 02 January. Flooding affected Villa Serrano municipality on 08 January 2023. Over 5,500 families were affected by flooding across La Paz, Beni and Santa Cruz Departments in Bolivia in early February. Two fatalities were reported, and dozens of homes and wide areas of crops were damaged or destroyed.

Global Warming

Ancient global warming event sheds light on Earth’s future

About 56 million years ago, our planet experienced one of the largest and fastest global warming events in the history. The so-called Paleocene-Eocene Thermal Maximum (PETM) was exceptional both in terms of its amplitude (with global temperatures rising by five to eight degrees Celsius) and its suddenness (about 5,000 years – a very short period on a geological scale).

By analyzing sediments collected from the deep waters of the Gulf of Mexico, a team of scientists led by the University of Geneva (UNIGE) has now found that this event – which led to the extinction of a vast number of terrestrial and marine species – was characterized by an increase in rainfall seasonality, which led to the movement of massive quantities of clay into the ocean, making it uninhabitable for many species.

Due to the similarities between PETM and current global warming – including possible causes such as high concentrations of carbon dioxide and methane in the atmosphere – the geological remains of this period are closely studied by scientists in order to gain insights to the future of our planet.

Wildfires

Wildfires – Chile

New and reactivated wildfires in south-central Chile are causing great concern in populated areas as some have destroyed buildings and left at least three people severely injured. Fires in the region of Biobio and Araucania have left a school and a church completely burned. As winds spread across the region, fires restarted again on Friday, she added. So far, the country has 256 active fires and 151 controlled fires, and that the main concern is that some of the active fires could move to “highly populated areas.”
