Shrinking Arctic glaciers are unearthing a new source of methane

Thu, 07/06/2023 - 11:45
As the Arctic warms, shrinking glaciers are exposing bubbling groundwater springs which could provide an underestimated source of the potent greenhouse gas methane, finds new research.

Tracking ships' icy paths amidst climate change

Wed, 07/05/2023 - 16:11
Understanding when and where ships are entering areas of Arctic sea ice can help better understand the potential impacts of vessel traffic in the region.

New study reveals abrupt shift in tropical Pacific climate during Little Ice Age

Mon, 07/03/2023 - 12:30
An El Niño event has officially begun. The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes. El Niño-like conditions can also occur on longer time scales of decades or centuries. This has been shown to have occurred in the recent past.

Acutely exposed to changing climate, many Greenlanders do not blame humans

Wed, 06/28/2023 - 19:13
A new survey shows that the largely Indigenous population of Greenland is highly aware that the climate is changing, and far more likely than people in other Arctic nations to say they are personally affected. Yet, many do not blame human influences -- especially those living traditional subsistence lifestyles most directly hit by the impacts of rapidly wasting ice and radical changes in weather.

Study of deep-sea corals reveals ocean currents have not fuelled rise in atmospheric carbon dioxide

Mon, 06/26/2023 - 15:42
Pioneering analysis of deep-sea corals has overturned the idea that ocean currents contributed to increasing global levels of carbon dioxide in the air over the past 11,000 years.

Effect of volcanic eruptions significantly underestimated in climate projections

Fri, 06/23/2023 - 09:54
Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.

Antarctic ice shelves experienced only minor changes in surface melt since 1980

Wed, 06/21/2023 - 15:46
A team of glaciologists set out to quantify how much ice melt occurred on Antarctica's ice shelves from 1980 to 2021. The results might seem to be good news for the region, but the researchers say there's no cause for celebration just yet.

Study shows ancient Alaskans were freshwater fishers

Fri, 06/16/2023 - 15:19
A scientific team has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas. The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.

We've pumped so much groundwater that we've nudged Earth's spin

Thu, 06/15/2023 - 17:31
By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study.

Climate change likely led to violence in early Andean populations

Thu, 06/15/2023 - 17:31
Climate change in current times has created problems for humans such as wildfires and reduced growing seasons for staple crops, spilling over into economic effects. Many researchers predict, and have observed in published literature, an increase in interpersonal violence and homicides when temperatures increase. Violence during climatic change has evidence in history, anthropology researchers say.

10-year countdown to sea-ice-free Arctic

Thu, 06/15/2023 - 09:53
Research team predicts Arctic without ice by the end of 2030s if current increasing rate of greenhouse gas emission continues.

The life below our feet: Team discovers microbes thriving in groundwater and producing oxygen in the dark

Wed, 06/14/2023 - 21:06
A survey of groundwater samples drawn from aquifers beneath more than 80,000 square miles of Canadian prairie reveals ancient groundwaters harbor not only diverse and active microbial communities, but also unexpectedly large numbers of microbial cells. Strikingly, some of these microbes seem to produce 'dark oxygen' (in the absence of sunlight) in such abundance that the oxygen may nourish not only those microbes, but may leak into the environment and support other oxygen-reliant microbes that can't produce it themselves.

Ancient herbivore's diet weakened teeth leading to eventual starvation, study suggests

Fri, 06/09/2023 - 11:57
Researchers have shed light on the life of the ancient reptile Rhynchosaur, which walked the earth between 250-225 million years ago, before being replaced by the dinosaurs.

South Africa, India and Australia shared similar volcanic activity 3.5 billion years ago

Thu, 06/08/2023 - 11:09
The Daitari greenstone belt shares a similar geologic make-up when compared to the greenstones exposed in the Barberton and Nondweni areas of South Africa and those from the Pilbara Craton of north-western Australia.

Thermal energy stored by land masses has increased significantly

Wed, 05/31/2023 - 14:01
There are many effects of climate change. Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ocean, the cryosphere and the land. 89 percent of this excess heat is stored in the oceans, with the rest in ice and glaciers, the atmosphere and land masses (including inland water bodies). An international research team has now studied the quantity of heat stored on land, showing the distribution of land heat among the continental ground, permafrost soils, and inland water bodies. The calculations show that more than 20 times as much heat has been stored there since the 1960s, with the largest increase being in the ground.

Ground beneath Thwaites Glacier mapped

Wed, 05/31/2023 - 13:51
The ground beneath Antarctica's most vulnerable glacier has now been mapped, helping scientists to better understand how it is being affected by climate change. Analysis of the geology below the Thwaites Glacier in West Antarctica shows there is less sedimentary rock than expected -- a finding that could affect how the ice slides and melts in the coming decades.

New method predicts extreme events more accurately

Wed, 05/24/2023 - 17:19
A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.

Montreal protocol is delaying first ice-free Arctic summer

Mon, 05/22/2023 - 15:16
New research shows that the 1987 global treaty, designed to protect the ozone layer, has postponed the occurrence of the first ice-free Arctic by as much as 15 years.

Ancient climate change solves mystery of vanished South African lakes

Fri, 05/19/2023 - 09:45
New evidence for the presence of ancient lakes in some of the most arid regions of South Africa suggests that Stone Age humans may have been more widespread across the continent than previously thought.

Past climate change to blame for Antarctica's giant underwater landslides

Thu, 05/18/2023 - 11:08
Scientists found weak, biologically-rich layers of sediments hundreds of meters beneath the seafloor which crumbled as oceans warmed and ice sheets declined. The landslides were discovered in the eastern Ross Sea in 2017, by an international team of scientists during the Italian ODYSSEA expedition, and scientists revisited the area in 2018 as part of the International Ocean Discovery Program (IODP) Expedition 374 where they collected sediment cores to understand what caused them.
