A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock.

The largest climate change in central North America since the age of the dinosaurs 65 million years ago, a temperature drop of nearly 15 degrees Fahrenheit, is documented within the fossilized teeth of horses and other plant-eating mammals, a new study reveals.

Researchers from the University of Leicester and the British Geological Society (BGS) have proposed storing carbon dioxide in huge underground reservoirs as a way of reducing emissions- and have even identified sites in Western Europe that would be suitable.

Their research, published in the journal, Planet Earth, reveals that CO2 can be contained in cool geological aquifers or reservoirs, where it can remain harmlessly for many thousands of years.

Light has been shed on the dark parts of the Moon with experiments by University of Edinburgh researchers simulating billions of years of lunar evolution.

It is generally believed the Moon was created after an early, semi molten, Earth collided with a planet the size of Mars.

The collision was so great that the orbiting debris would have formed a so-called lunar magma ocean, or liquefied rock, up to several hundred kilometres deep that would have covered the Moon's surface.

Carbon dioxide, a greenhouse gas that has become a bane of modern society, may have saved Earth from freezing over early in the planet's history, according to the first detailed laboratory analysis of the world's oldest sedimentary rocks.

The climate system, and in particular sea level, may be responding more quickly to rising carbon emissions than climate scientists have estimated with climate models.

An international team of climate scientists has cautioned against suggestions that the Intergovernmental Panel on Climate Change (IPCC) has previously overestimated the rate of climate change.

A giant cloud half the size of the United States has been imaged on Saturn’s moon Titan by the Cassini spacecraft. The cloud may be responsible for the material that fills the lakes discovered last year by Cassini's radar instrument.

Cloaked by winter's shadow, this cloud has now come into view as winter turns to spring. The cloud extends down to 60 degrees north latitude, is roughly 2400 kilometers in diameter and engulfs almost the entire north pole of Titan.
