A new study led by the University of Exeter challenges the perception that recent extreme floods in various parts of the world are unprecedented events. Through the analysis of geological records of paleofloods, the researchers have identified episodes of river floods of greater magnitude than those recorded today, highlighting the need for a broader historical […]

The World’s Lakes Are Changing Color—An Alarming Sign of Water Quality and Ecosystem Alteration
Lakes are a fundamental component of terrestrial ecosystems. They not only serve as habitats for countless aquatic and terrestrial species but also play a key role in climate regulation and the supply of drinking water. Their influence extends to agriculture, ecological balance, and atmospheric humidity. However, recent studies have revealed a concerning transformation in their […]

Decline of the Eastern Roman Empire Was Not Caused by Plagues and Climate Change in 6th Century AD, But Rather Experienced a Population Boom
A recent study published in the journal Klio by researchers Haggai Olshanetsky, from the University of Warsaw, and Lev Cosijns, from the University of Oxford, analyzes the true causes of the decline of the Eastern Roman Empire. Traditionally, it has been believed that natural factors, such as the Late Antique Little Ice Age (LALIA) and […]

The Greatest Climate Catastrophe in Human History May Have Originated the Myth of Ragnarok and Led to the Invention of Rye Bread
In Norse mythology, the end of the world, Ragnarok, begins with a three-year winter with no intervening summers: the Fimbulvetr. Now, a new research study from the National Museum of Denmark, published in the Journal of Archaeological Science Reports, shows that the myth could have roots in a real climate catastrophe that occurred 1,500 years […]

Anomalous El Niño Events Caused the Largest Mass Extinction in Earth’s History
A groundbreaking study published in Science, co-led by researchers from the University of Bristol and China University of Geosciences (Wuhan), has uncovered new insights into the causes of the most catastrophic mass extinction in Earth’s history: the Permian-Triassic extinction. This event, which took place around 252 million years ago, wiped out approximately 90% of marine […]

An experiment begun nearly 100 years ago secures the future of beer and whiskey in the face of climate change
Nearly a century ago, an experiment was initiated that could secure the future of beer and whiskey production in the face of climate change. This experiment has allowed researchers to identify the genes responsible for the remarkable adaptability of barley, a key ingredient in both beverages. As climate change accelerates, these findings could be crucial […]

By 2100, Ships Could Sail Year-Round Through the Northern Sea Route in the Arctic, Changing Geopolitics and Global Trade
A team of researchers led by Pengjun Zhao has presented a revealing report on the future of maritime trade in the Arctic, specifically along the Northern Sea Route. This study, published in the journal Communications Earth & Environment, explores how climate change could allow navigation along this route year-round by the year 2100. Currently, Arctic […]

Evidence of 6 Climate Changes Due to Variations in Earth’s Axial Tilt One Million Years Ago, Found in Southern Spain
A team of researchers has identified up to six climate episodes that occurred about a million years ago at the Quibas site, located in the town of Abanilla (Murcia, Spain). These findings, published in the journal Quaternary International, reveal a significant climate alternation for that period in Europe, marking the first time this pattern has […]

Icebergs in Constantinople and a Frozen Black Sea: Climate Anomalies Triggered by Eruptions in Iceland at the Beginning of the Middle Ages
It was one of the coldest winters the region has experienced: in the year 763, large areas of the Black Sea froze, and icebergs were seen in the Bosphorus. Contemporary historians recorded this unusual weather phenomenon during the winter of 763/764 in their accounts of Constantinople, now Istanbul. Now, an international and interdisciplinary study conducted […]

Simple Equations Shed Light on the Enigma of How Clouds Will Affect Future Climate Change
The effect of clouds has been the biggest uncertainty in predictions about global warming. In this new study, researchers from the University of Exeter and the Laboratory of Dynamical Meteorology in Paris created a simple model to see how changes in anvil clouds could impact warming. Anvil clouds are common storm clouds in the tropics […]
