New Study Reveals Abrupt Shift in Tropical Pacific Climate During Little Ice Age

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 ...

Acutely Exposed to Changing Climate, Many Greenlanders Do Not Blame Humans

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 ...

Study of Deep-Sea Corals Reveals Ocean Currents Have Not Fuelled Rise in Atmospheric Carbon Dioxide

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 ...

Effect of Volcanic Eruptions Significantly Underestimated in Climate Projections

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 ...

Montreal Protocol Is Delaying First Ice-Free Arctic Summer

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 ...

Ancient Climate Change Solves Mystery of Vanished South African Lakes

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 ...

Past Climate Change to Blame for Antarctica's Giant Underwater Landslides

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 ...

About 13,000 Years Ago, the Water Outflow from the Mediterranean to the Atlantic Ocean Was Twice That of Today’s

About 13,000 years ago, a climate crisis caused a global drop in temperatures in the northern hemisphere. This episode of intense cold, known as the Younger Dryas, also caused severe aridity across ...

'Warm Ice Age' Changed Climate Cycles

Approximately 700,000 years ago, a 'warm ice age' permanently changed the climate cycles on Earth. During this exceptionally warm and moist period, the polar glaciers greatly expanded. A ...

South Africa's Desert-Like Interior May Have Been More Inviting to Our Human Ancestors

Lining the Cape of South Africa and its southern coast are long chains of caves that nearly 200,000 years ago were surrounded by a lush landscape and plentiful ...

Out of This World Control on Ice Age Cycles

A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show ...

Great Basin: History of Water Supply in One of the Driest Regions in the USA

An international team has reconstructed the evolution of groundwater in the Great Basin, USA -- one of the driest regions on Earth -- up to 350,000 years into the past with unprecedented accuracy. ...

Human Ancestors Preferred Mosaic Landscapes and High Ecosystem Diversity

A new study finds that early human species adapted to mosaic landscapes and diverse food resources, which would have increased our ancestor's resilience to past shifts in ...

Dark Clouds on the Horizon

Our industrialized society releases many and various pollutants into the world. Combustion in particular produces aerosol mass including black carbon. Although this only accounts for a few percent of ...

Researchers Discover a Cause of Rapid Ice Melting in Greenland

While conducting a study of Petermann Glacier in northwest Greenland, researchers uncovered a previously unseen way in which the ice and ocean interact. The glaciologists said their findings could ...

Pollen Production Could Impact Climate Change by Helping Clouds Form

For millions of people with seasonal allergies, springtime means runny noses, excessive sneezes and itchy eyes. And, as with many things, climate change appears to be making allergy season even ...

Vanishing Glaciers Threaten Alpine Biodiversity

With glaciers melting at unprecedented rates due to climate change, invertebrates that live in the cold meltwater rivers of the European Alps will face widespread habitat loss, warn researchers. Many ...

Researchers Discover That the Ice Cap Is Teeming With Microorganisms

Greenlandic ice is teeming with life, both on the surface and underneath. There are microscopic organisms that until recently science had no idea existed. There is even evidence to suggest that the ...

West Antarctic Ice Sheet Retreated Far Inland, Re-Advanced Since Last Ice Age

The West Antarctic Ice Sheet is melting rapidly, raising concerns it could cross a tipping point of irreversible retreat in the next few decades if global temperatures rise 1.5 to 2.0 degrees Celsius ...

The Future Is Foggy for Arctic Shipping

As the Arctic warms and loses sea ice, trans-Arctic shipping has increased, reducing travel time and costs for international trade. However, a new study finds that the Arctic Ocean is getting foggier ...
