All-natural, not so long ago, hugely destructive, and a repeat would devastate people and planet

The interglacial periods are initiated by amplification and terminated by reduction of the insolation due to the eccentricity through the precession index.

The main point of the paper is that the 100,000-year and 41,000-year inter-glacial cycles that are the subject of the "100,000-year problem" never existed.

As well defined turning points in response and a limit-cycle of operation are long established characteristics of relay control systems, I submit that Earth’s climate regulation is non-linear in much the way a relay controller...

Cruise leader Gerhard Bohrmann summarizes: "At the end of the SUGAR-3 programme, the drilling campaign with MeBo200 in the Black Sea showed us once again very clearly how quickly the methane hydrate stability in the ocean...

Until now, mathematical models of the last ice age could not reconcile the height of the sea level and the thickness of the glacier masses: the so-called Missing Ice Problem.

A new study, in which the Andalusian Earth Sciences Institute (IACT) (CSIC-UGR) participated, has described for the first time a key stage in the beginning of the great glaciations and indicates that it can happen to our...

UIT THE ARCTIC UNIVERSITY OF NORWAY Research News 10,000 km2 of ice disappeared in a blink of an eye from an ice sheet in the Storfjorden Through offshore Svalbard, a…

From Physics Today Gradual falls and sharp rises in temperature for millions of years have profoundly affected living conditions on the planet and, consequently, our own evolution...

By Andy May The phrase “Ice Age” is poorly defined and often abused, so let’s first define the climate state during most ice ages. It is called “Icehouse Earth.” The earth is in an icehouse state...

University of Copenhagen Ice core research: Researchers from the section Physics of Ice, Climate and Earth (PICE) at the Niels Bohr Institute, University of Copenhagen, have succeeded in making a method to enlighten an otherwise...

A thread from a few days ago. I was a huge believer in Climate Change as a youth. I wanted to save the environment. Then I caught one lie. Then two. Then three. Then I read the current data. Then I realized they’ve been...

Guest Opinion; Dr. Tim Ball A recent article in the British newspaper The Express titled, “Northern Lights in the UK: Can you watch Aurora Borealis from UK? Where can you see it?” raises interesting questions and comparisons...

Guest essay by Eric Worrall Paleo-climate experts have advanced a theory that weathering of Indonesian mountain ranges is starving the planet of CO2, which is keeping the Earth locked in the ongoing Quaternary ice age...
