Research has shown that glaciers during the ice age are prone to flooding
Dr. George’s vehicle in front of a lakeless lake in British Columbia (Canada), the lake is covered by the Tarquesque glacier in the background and is empty several times a year. Credit: Natalie Lützow/UniversitätPotsdam Scientists have long debated whether the population of mountainous regions is increasingly at risk from meltwater floods as meltwater glaciers release more and more water. A…

Research is discovered that the carbon capture of the constructed wetland decreases with age.
Credit: Pixabay/CC0 Public domain A new study suggests that the constructed wetlands do good jobs in the early days of capturing carbon in an environment that contributes to climate change, but the abilities will decrease over time as the wetlands mature. 。 Researchers investigate soil core samples collected from two constructed freshwater wetlands, and compare them with previous research data…

Seaweed farms show potential for carbon storage that gets better with age
Location of sampled seaweed farms, time elapsed (years) since the start of farming and the size of the harvested area (HA). Credit: Natural Climate Change (2025). doi:10.1038/s41558-024-02238-1 A large team of researchers from diverse backgrounds has found evidence that carbon storage beneath seaweed can accumulate as much carbon as some blue carbon habitats. In their study, published in Nature Climate…

New research reveals deep-sea clues that solve the mysteries of the ice age 1 million years ago
Researchers analyzed sediment core samples collected by D/V JOIDES Resolution near Cape Town, South Africa. Their discoveries reveal details about changes in temperature and salinity in the deep ocean, as well as the history of mixing of water originating from both the Northern and Southern Hemispheres.

Earth experienced a period of massive and rapid melting after the last ice age, new research suggests
Credit: CC0 Public Domain At the end of the last global ice age, the frigid Earth reached a pre-built limit of climate change and melted into a slimy planet. The results of the Virginia Tech-led study show direct evidence of a slushy planet (also known as the “Plume World Ocean” era), when sky-high carbon dioxide concentrations sent the frozen Earth…

Shipwreck bones suggest being right- or left-handed may influence chemical changes in the clavicle as you age
A living ship viewed from the center of the ship toward the bow. The scenery projected on the hull reflects the activities that took place in each area. The “players” are volunteers and staff, wearing copies of clothing and using replicas of artifacts. To the left is the main deck gallery containing authentic artifacts, located opposite where they were discovered…

Ice age clues and advanced climate models reveal how El Niño weather patterns change
An 8x microscope image of washed tropical marine sediments shows a large number of foraminifera shells. Credit: Kaustubh Tirumalai, University of Arizona The last ice age peaked about 20,000 years ago, with massive glaciations and dramatic climate changes that transformed Earth’s oceans, landscapes and ecosystems. According to a study led by the University of Arizona, Earth’s last ice age could…
