PFBTA: Newly discovered greenhouse gas ’7,000 times more potent than CO2′
December 13, 2013
Researchers at University of Toronto have discovered a new greenhouse gas that is 7,000 times more powerful than carbon dioxide to cause greenhouse effect which causes warming of the Earth.
As per the scientists, the newly discovered gas, PerFluoroTriButylAmine (PFTBA), has been in use by the electrical industry since the mid-20th century.
The discoverers have claimed that PFTBA which does not occur naturally has thehighest radiative efficiencyof any molecule detected in the atmosphere up to now.
The study showed that PFTBA was 7,100 times more powerful at warming the Earth over a 100-year time period than CO2. This gas remains in the atmosphere for about 500 years, and unlike CO2 which is absorbed by forests and oceans, there are no known natural “sinks” on Earth to absorb it.
Do we need to worry about PFTBA?
Not at current levels. The current concentration of PFTBA in the atmosphere is very low as compared to CO2 so it does not displace the focus of our concerns from the burning of fossil fuels such as oil and coal as the main drivers of climate change. However, higher concentration of the gas would contribute to a serious global warming. So we need to ponder over using such compounds in large quantity without first understanding their impact on climate change.
The Reserve Bank of India has granted license to Doha Bank to start bankingoperations in India and has allowed it to open a branch in Mumbai to provide full-scale banking services.
Doha Bankwhich is thelargest commercial bank in the state ofQatarintends to expand its operations at the local, regional and international levels. The bank will soon start operations as a foreign bank branch in Mumbai and will offer wholesale banking, retail banking, treasury and trade finance services to all customers in India.
This licence will further boost the niche role Doha Bank is playing and facilitating the movement of trade between Qatar and India. Qatar-India bilateral annual trade is about $16 billion and there are huge opportunities of growth available ininfrastructure and other sectors in India.
There is a large diaspora of Indian population in Qatar and various Indian companies are active in infrastructure projects. As per Doha Bank, the licence will pave the way for the bank to support all expatriates with its solutions especially remittance solutions.
