Switching on the Atlantic Ocean heat pump

34 million years ago the warm ‘greenhouse climate’ of the dinosaur age ended and the colder ‘icehouse climate’ of today commenced. Antarctica glaciated first and geological data imply that the Atlantic meridional overturning circulation, the global ocean conveyor belt of … Continue reading

Collapse of the Atlantic Ocean heat transport might lead to hot European summers

Severe winters combined with heat waves and droughts during summer in Europe. Those were the consequences as the Atlantic Ocean heat transport nearly collapsed 12,000 years ago. The same situation might occur today. Paleontology News — ScienceDaily

New concept explains how Earth’s inside core stays strong regardless of excessive warmth

Diagram illustrating the interior construction of the Earth Even although it’s hotter than the floor of the Sun, the crystallized iron core of Earth stays strong. A new research from KTH Royal Institute of Technology in Sweden might lastly settle … Continue reading

Heat from earth’s core could be underlying force in plate tectonics

Heat from earth’s core could be underlying force in plate tectonics For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are … Continue reading

Earth’s magnetic fields could track ocean heat

Track of Sanba overlaid on Sea Surface Temperature + Ocean Heat Content products As Earth warms, much of the extra heat is stored in the planet’s ocean — but monitoring the magnitude of that heat content is a difficult task. … Continue reading

Meteorite impact 55 million years ago may have caused Earth to heat up

Around 55 million years ago, Earth experienced a series of sudden and extreme global warming events, known as the Paleocene-Eocene Thermal Maximum (PETM). A comet smashing into ancient Earth may have set off catastrophic global warmingResearchers have found evidence that … Continue reading

Study finds ‘frictional heat’ as a new trigger for explosive volcanic eruptions

Understanding magma ascent is central to forecasting volcanic disasters. However, it is not possible to always successfully predict volcanic events due to the lack of complete knowledge of the signals leading to catastrophes. (Stock image) A new study into magma … Continue reading

Frictional heat dehydrates magma

The volcano Santiaguito in Guatemala. In contrast to the conventional view, new findings demonstrate that frictional heat in rising magma can drive outgassing of water vapor, which contributes to the dehydration of molten magma – and reduces the pressure in … Continue reading
