'True polar wander' and Earth's ice ages

Rice University geophysicists have determined Earth shifted relative to its spin axis within the past 12 million years, which caused Greenland to move far enough toward the north pole to kick off the ice age that began about 3.2 million years ago. The study is based...

How glaciers disappeared from Scotland at the end of the last Ice Age

Research led by a Stirling academic, Dr. Tom Bradwell, has revealed how glaciers disappeared from Scotland at the end of the last Ice Age. Bradwell led a research team in taking samples offshore around the north-west of Scotland, and Shetland. The activity was part...

One of the greatest mass extinctions caused by volcanic eruptions

Scientists have linked global mass extinction at the Permian-Triassic boundary some 250 million years ago to an ice age caused by the activity of the first volcanism in the Siberian Traps. The research paves the way for a new vision of the Earth's climate...

Study links Earth's orbital variations, sea ice and ice ages

Earth is currently in what climatologists call an interglacial period, a warm pulse between long, cold ice ages when glaciers dominate our planet's higher latitudes. For the past million years, these glacial-interglacial cycles have repeated roughly on a...

Study claims new 'Little Ice Age' already underway

The Head of Space Research Laboratory at the Pulkovo Observatory of the Russian Academy of Sciences in St. Petersburg, Dr. Habibullo Abdussamatov, announced the new Little Ice Age started at the end of 2015. According to the new research, our Sun has been in the...

Greenland 'Warm Blob' surface water responsible for abrupt climate swings in the last ice age

New research shows a "warm blob" of surface water in the Atlantic played a significant role on the wild climate swings in Greenland during the last ice age. Researchers used the foraminifera fossils to compare the changes in the ocean temperature with the...

Ice age in Jurassic Period caused by a major volcanic event

An international team of researchers has found the evidence of link between the large-scale volcanic event and the large and abrupt cooling of the Earth's temperature during the Jurassic Period, the University of Exeter reported on December 11, 2015. The...

UK Met Office: The return of 'grand solar minimum' could affect European and eastern US winters, but wouldn't halt global warming

A return to low solar activity not seen for centuries could increase the chances of cold winters in Europe and eastern parts of the United States but wouldn't halt global warming, according to new research led by UK's Met office and published recently in Nature

Global Warming in the Ice Age

The melting of the glacial ice sheets in North America, Europe and elsewhere was a stochastic process.Long periods of slow melting alternated with bursts of accelerated melting. Between the Late Glacial Maximum and the early Holocene, global sea level rose by 100 to 130

Icebergs drifted to Florida during last ice age

Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21 000 years ago, oceanographer Alan Condron of the University of Massachusetts Amherst has shown that icebergs and meltwater from the North American i

A shocking study - regional climate influenced by the Sun

A new study from Lund University in Sweden has, for the first time, reconstructed solar activity during the last ice age and showed that the regional climate is influenced by the Sun.For the first time, a research team has been able to reconstruct the solar activit

Minor variations in the ice sheet size sufficient to trigger abrupt climate changes

Over the past one hundred thousand years cold temperatures largely prevailed over the planet in what is known as the last ice age. However, the cold period was repeatedly interrupted by much warmer climate conditions. Scientists have long attempted to find out why these

The_Greatest_Science_Challenge_in_the_History_of_Civilization

"The Greatest Science Challenge in the History of Civilization" - a video by Rolf A. F. Witzsche

The challenge is, to respond in the most efficient manner to the largest, impending, physical event in the history of civilization, in the form of the start of the next Ice Age with the Sun going inactive sometime in the 2050s timeframe. The challenge is so great that i

Research provides new theory on cause of ice age 2.6 million years ago

New research published today, Friday, June 27, 2014, in the journal Nature Scientific Reports has provided a major new theory on the cause of the ice age that covered large parts of the Northern Hemisphere 2.6 million years ago.The study, co-aut

Volcanoes_Helped_Species_Survive_Ice_Ages

Volcanoes helped species survive ice ages

An international team of researchers has found evidence that the steam and heat from volcanoes and heated rocks allowed many species of plants and animals to survive past ice ages, helping scientists understand how species respond to climate change. The research

Global warming actually decreases storm activity, says science paper

Current weather patterns are changing, we are constantly told by everyone from President Obama during his most recent State of the Union Address on down through various academic circles. And few of us dispute that; weather, after all, changes over time, as

Our changing climate and the variable Sun

Solar physicists around the world today are wondering: has the Sun fallen silent? In 2013, the Sun began the peak phase of its 11-year sun spot cycle called the Solar Maximum when sunspot production should be at its highest. However, the lack of sunspot activity has

Why current climate is anomaly, and ice age climate is normal Earth's climate

The Ice Age isn't coming, because it is already here. According to author and researcher Rolf Witzsche the Ice Age Climate is the normal climate for the Earth and it has been for more than 85% of the last million years. Because glaciation
