The Atlantic Ocean at mid-depths may have given out early warning signals – 1,000 years in advance – that the last Ice Age was going to end, scientists report today in the journal Paleoceanography.
The rate at which carbon emissions warmed Earth’s climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, researchers have found.

A team of researchers from Caltech and the China Earthquake Administration has discovered an ancient, deep canyon buried along the Yarlung Tsangpo River in south Tibet, north of the eastern end of the Himalayas.
If you want to see into the future, you have to understand the past. An international consortium of researchers under the auspices of the University of Bonn has drilled deposits on the bed of Lake Van (Eastern Turkey) which provide unique insights into the last 600,000 years.
This at least is what the geologist Prof. Dr. Ulrich Schreiber and the physico-chemist Prof. Dr. Christian Mayer of the University of Duisburg-Essen in Germany are convinced of.
New analysis of geologic history can potentially solve the riddle of the ‘Cambrian explosion’.
The research conducted by Ryan McKellar’s sounds like it could of come straight out of Jurassic Park: he studies pieces of amber found buried with dinosaur skeletons. However, instead of re-creating dinosaurs, McKellar uses the tiny pieces of fossilised tree resin to study a world where the extinct animals thrived.
UCSB geochemist uses helium and lead isotopes to obtain a better understanding of the makeup of the planet’s deep interior.
Scientists have uncovered evidence for a huge mountain range that sustained an explosion of life on Earth 600 million years ago.
Professor Zunli Lu uses geochemistry and micropalaeontology to track oxygen levels in global oceans.
The Tibetan Plateau in south-central Asia, because of its size, elevation and impact on climate, is one of the world’s greatest geological oddities.
The eruption occurred just before the 1815 Tambora volcanic eruption, which is famous for its overwhelming impact on climate worldwide, with 1816 given memorable names such as ’Eighteen-Hundred-and-Froze-to-Death’, the ‘Year of the Beggar’ and the ‘Year Without a Summer’ due to unseasonal frosts, crop failure and famine across Europe and North America. The extraordinary conditions are considered to have inspired literary works such Byron’s ‘Darkness’ and Mary Shelley’s ‘Frankenstein’.
The warm Atlantic water continued to flow into the icy Nordic seas during the coldest periods of the last Ice Age.
Geologists from Trinity College Dublin have rewritten the evolutionary history books by finding that oxygen-producing life forms were present on Earth some 3 billion years ago – a full 60 million years earlier than previously thought.
The influence of climate on agriculture is believed to be a key factor in the rise and fall of societies in the Ancient Near East. Dr. Simone Riehl of Tübingen University’s Institute for Archaeological Science and the Senckenberg Center for Human Evolution and Palaeoenvironment has headed an investigation into archaeological finds of grain in order to find out what influence climate had on agriculture in early farming societies.
Western Wall Wearing Away? Discovery of Extreme Erosion Process Could Guide New Preservation Techniques
Researchers from the Hebrew University of Jerusalem investigated erosion in the different types of limestone in the Western Wall located at the foot of Jerusalem’s Temple Mount. Stones comprised of large crystals were almost unchanged in 2000 years, while limestone containing small crystals eroded much faster and in some cases had receded by tens of centimeters, potentially weakening the wall’s structure. The researchers describe an accelerated erosion process that explains why some rocks are more weathered than others, and displayed that chemo-mechanical erosion extends down to the tiny micron scale. The findings could have significant implications for regional and global carbonate weathering, and could help guide the development of effective preservation techniques that slow the rate of erosion in order to protect cultural heritage sites around the world.
Scientists are searching through an extremely large collection of 20-million-year-old amber unearthed in the Dominican Republic over 50 years ago; the effort is displaying new insights into ancient tropical insects and the world they lived in.
In Jeju, renowned as an attractive holiday destination with natural tourism resources, a recent study unveiled a volcanic eruption occurred on the island. The Korea Institute of Geoscience and Mineral Resources (KIGAM) discovered traces that showed that a recent volcanic eruption was evident 5,000 years ago. That is the first time to actually find out the date when lava spewed out of a volcano 5,000 years ago in the inland part of the island as well as the one the whole peninsula.
Electrical images show flows of fluids to magma chamber.
Amber is known as one of the most beautiful gemstones and its mysterious qualities were enough to inspire myths and legends many years ago, and the fossilized tree resin still manages to lock away secrets today.

A geologist studied fossils to confirm that stones used in 19th century Ohio grain mills originated from France.
A Curtin University researcher has shown that ancient volcanic eruptions in Australia 510 million years ago significantly affected the climate, causing the first known mass extinction in the history of complex life.
The discovery of an ancient ring-like structure in southern Alberta suggests the area was struck by a meteorite large enough to leave an eight-kilometre-wide crater, producing an explosion strong enough to destroy present-day Calgary, say researchers from the Alberta Geological Survey and University of Alberta.
Glaciers and ice sheets are commonly thought to work like a belt sander. As they move over the land they scrape off everything — vegetation, soil and even the top layer of bedrock.
An inscription on a 3,500-year-old stone block from Egypt may be one of the world’s oldest weather reports—and could provide new evidence about the chronology of events in the ancient Middle East.
Will the dating of the volcanic eruption of Santorini remain an unsolved mystery? The question whether this natural disaster occurred 3,500 or 3,600 years ago is of great historiographical importance and has indeed at times been the subject of heated discussion among experts.
