Research suggests Earth's oldest continental crust is disintegrating
Earth's continental configurations have changed dramatically over its billions of years' history, transforming not only their positions across the planet, but also their topography as expansion and contraction of the crust ...
Arctic ozone reaches record high in positive step for climate
Earth's ozone layer holes over polar regions, where the stratospheric ozone level is significantly depleted, have been a prevalent feature of climate change news in recent decades. Anthropogenic-sourced chlorofluorocarbons ...
Why is Mount Everest so big? New research highlights a rogue river—but deeper forces are at work
Mount Everest (also known as Chomolungma or Sagarmāthā) is famously the highest mountain in the Himalayas and indeed on Earth. But why?

Limestone and iron reveal puzzling extreme rain in Western Australia 100,000 years ago
Almost one-sixth of Earth's land surface is covered in otherworldly landscapes with a name that may also be unfamiliar: karst. These landscapes are like natural sculpture parks, with dramatic terrain dotted with caves and ...

Capturing finer-scale topographic differences improves Earth system model capability to reproduce observations
Earth system models (ESMs), used in climate simulations and projections, typically use grids of 50–200 km resolution. These are considered relatively coarse with limited ability to resolve land surface variability.

Researchers investigate changes in atmospheric CO₂ levels between glacial and interglacial climates
Paleoclimate scientists are trying to understand the causes of the ~90 parts per million (ppmv) atmospheric CO2 swings between glacial and interglacial climates. Even though these cycles between cold and warm periods seem ...

Extensive afforestation and reforestation can brake global warming
The Paris Agreement calls on us to limit global warming to 1.5 degrees Celsius above pre-industrial levels. To reach this goal, we need to reduce CO₂ emissions and remove existing CO₂ from the atmosphere.

Some microbes used poison gas in battle for iron in the Earth's early oceans, geomicrobiologists find
Early in the Earth's development, the atmosphere contained no oxygen. Yet the iron dissolved in the oceans was oxidized in gigantic quantities and deposited as rock. It can be seen today, for example, as banded iron ore in ...

Study: Wildfires will make the land absorb much less carbon, even if warming is kept below 1.5°C
One of the aims of the Paris Agreement was to "pursue efforts" to keep global warming below 1.5°C, but even this ambitious target would not stop the land's ability to absorb carbon weakening as wildfires become fiercer and ...

Mathematicians and climate researchers build new models for understanding polar sea ice
Polar sea ice is ever-changing. It shrinks, expands, moves, breaks apart, reforms in response to changing seasons, and rapid climate change. It is far from a homogenous layer of frozen water on the ocean's surface, but rather ...
