In a new research, scientists have found for the first time that ethane and heavier hydrocarbons can be synthesised under the pressure-temperature conditions of the upper mantle of the Earth.
The research was conducted by scientists at the Carnegie Institution’s Geophysical Laboratory, with colleagues from Russia and Sweden.
Methane (CH4) is the main constituent of natural gas, while ethane (C2H6) is used as a petrochemical feedstock.

The term Global warming refers to the gradual rise in the earth’s temperature. Global warming has been an environmental issue that has plagued the entire globe for a few years now and researchers have said that the global warming will cause a complete change on the planet, with the same catastrophic effects as the ice age. Small effects can be seen already in the North and South Poles, where the ice bergs are beginning to melt. There is also evidence of the sea levels rising in certain areas.
Global warming has been directly attributed to the hole in the ozone layer which is causing the heating up of the earth’s atmosphere from the sun. This is commonly referred to as the greenhouse effect. It is said that if the hole in the ozone layer continues to grow, global warming could accelerate quite dramatically. This is why many countries have come together and signed agreements to cut down on fuel emissions into the atmosphere and use various other forms of energy that are safe for the ozone layer.
