Ice cores drilled in Antarctica and Greenland have revealed gigantic volcanic eruptions during the last ice age. Sixty-nine of these were larger than any eruption in modern history. According to the University of Copenhagen...

Many of today's climate models rely on past levels of greenhouse gasses and aerosols to validate their predictions for the future. But there's a problem: While pre-industrial levels of greenhouse gasses are well documented,...

We panic about the next half degree of warming (above the 1.5 we’ve already had) but the depth of the ice age was savagely cold. For years the experts told us what Earths temperature was then, but apparently they were...

Guest “geologizing” by David Middleton Geology rocks! Substance found in Antarctic ice may solve a martian mysteryBy Tess Joosse Jan. 26, 2021 Researchers have discovered a common martian mineral deep…

From Nature An analysis of air up to 2 million years old, trapped in Antarctic ice, shows that a major shift in the periodicity of glacial cycles was probably not caused by a long-term decline in atmospheric levels of carbon...

Università Ca’ Foscari Venezia Volume 90% Click here for project video. On 1st June 2019 the European Beyond EPICA Oldest Ice Core project started with the aim of drilling for and recovering ice from up to 1.5 Million...

Guest post by David Middleton Why bother with Argo floats and ocean heat content?  Now the average temperature of the oceans can be instantly calculated by the ratio of noble gasses in the atmosphere… New Study Identifies...

Guest Post by Willis Eschenbach In the first part of this disquisition, I discussed the oddity that the warmer it gets around Antarctica, the more ice accumulates on the Antarctic ice cap...

Guest Post by Willis Eschenbach In investigations of the past history of cosmic rays, the deposition rates (flux rates) of the beryllium isotope 10Be are often used as a proxy for the amount of cosmic rays...

Believers really do have trouble with numbers. Today 400 is apparently a lot like zero.

Nice video about ice cores, and how they are used in climate science.

On Friday, Jan. 28 in Antarctica, a research team investigating the last 100,000 years of Earth’s climate history reached an important milestone completing the main ice core to a depth of 3,331 meters (10,928 feet)...
