Recently, a new study has revealed that carbon dioxide released from the Deep Ocean helped in ending the last Ice Age.
The study showed that carbon stored in an isolated reservoir deep in the Southern Ocean re-connected with the atmosphere, driving a rise in atmospheric CO2 and an increase in global temperatures.
Carbon Dioxide Conversion to Methanol Made Easier!
A clean, low-cost way to convert carbon dioxide into methanol, an ingredient used in the production of plastics, solvents and adhesives has now been discovered by researchers

The finding gave scientists an insight into how the ocean affects the carbon cycle and climate change.
Atmospheric CO2 levels fluctuate from about 185 parts-per-million (ppm), during ice ages, to around 280 ppm, during warmer periods like today (termed interglacials). The oceans currently contain approximately sixty times more carbon than the atmosphere and that carbon can exchange rapidly (from a geological perspective) between these two systems (atmosphere-ocean).

Malaria-spreading mosquitoes require minute changes in concentrations of exhaled carbon dioxide to know whether you are at home or not, which then triggers them to land on human skin.
The international team studied the composition of the calcium carbonate shells of ancient marine organisms that inhabited the surface of the ocean thousands of years ago in order to trace its carbon content.
Patrizia Ziveri, ICREA professor at the ICTA, UAB, said that these results will help to better understand the dynamics of human-induced CO2 accumulation in the atmosphere since the ocean was an important carbon sink and the largest reservoir of carbon on our planet.
The study is published in Nature.
