North Atlantic played key role in last climate transition

The North Atlantic Ocean played a key role in the last climate transition, says a study providing valuable insights into why large continental ice-sheets first grew in North America and Scandinavia some 2.7 million years ago.

Explosive volcanism drove major changes in 'Snowball Earth'

According to a new research, around 720-640 million years ago, much of the Earth's surface was covered in ice during a glaciation that lasted millions of years. Explosive underwater volcanoes were a major feature of this 'Snowball Earth'.

Climate can grind mountains faster than imagined

The study, conducted by a team of scientists from 10 countries, culminated more than a decade of fieldwork.

Warming potential of clouds could explain how Earth thawed out

Scientists have found that the greenhouse potential of clouds, which had been overlooked in previous research, could explain how a Snowball Earth may have melted.

Glaciation not related to carbon isotopic ratio

Washington: The large changes in the carbon isotopic composition of carbonates which occurred prior to the major climatic event more than 500 million years ago, known as `Snowball Earth`.

Global warming likely to delay next ice age

Researchers have warned that unprecedented levels of greenhouse gases in the Earth’s atmosphere are disrupting normal patterns of glaciation.
