Four new human-made ozone depleting gases found in the atmosphere

Scientists at the University of East Anglia have identified four new man-made gases in the atmosphere – all of which are contributing to the destruction of the ozone layer.

New research published today in the journal Nature Geoscience reveals that more than 74,000 tonnes of three new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been released into the atmosphere.

Introduction: Ozone Layer Depletion

The distribution of ozone in the stratosphere is a function of altitude, latitude and season. It is determined by photochemical and transport processes. The ozone layer is located between 10 and 50 km above the Earth's surface and contains 90% of all stratospheric ozone. Under normal conditions, stratospheric ozone is formed by a photochemical reaction between oxygen molecules, oxygen atoms and solar radiation. Read more here.

World Ozone Day - 16 September 2012

In 1998, in recognition of the Protocol's unique accomplishments, the General Assembly in its Resolution 49/114 named 16 September as the International day for the Preservation of the Ozone Layer. Since that time, the Parties have used this day to celebrate the signing of the Montreal Protocol, and the significant environmental and health benefits that this amazing treaty has yielded.

The Montreal Protocol is celebrating its 25th Anniversary this year.

Do not get over excited over happiness and do not get over depressed over sorrow.

Do not get over bonded with anyone and anybody because it can lead to problems and sorrow.

Never think that my duty is the topmost or lowermost. Every duty is respectful. The responsibility undertaken or given as per the position is the noblest duty.

Elevate yourselves, family, society and nation and never denigrate yourselves, family, society and nation.

We are our own closest relatives and if not properly utilised we will become our closest enemies.

There are possibilities of success and failure in any endeavour. One cannot assure success always.

Death is inevitable for everyone in this world. In any endeavour at the maximum an individual may die.

People may say good and also they may say bad. Approach them with stabilised mind.

Take anything after scientifically, logically and rationally analysing them.

Perform your duty, responsibility and accept the privileges eligible for you.

First change ourselves and then try to change others.

We are all instruments /tools in the hands of the nature for performing the duty. So do not think that I am doing the duty. Think that I am an instrument to do the duty.

Results of action may not be sweet always. Accept what ever may be the result.

Follow the path of great scholars who guided the world. Listen their messages.

Results and rewards will come and go but stick to your duty with devotion, dedication and sincerity.

च्छायामन्यस्य कुर्वन्ति तिष्ठन्ति स्वयमातपे ।
फलान्यापि परार्थाय वृक्षाः सत्पुरुषाः इव ॥

जलबिन्दुनिपातेन क्रमशः पूर्यते घटः ।

अग्निशेषमृणशेषं शत्रुशेषं तथैव च |

अहो दुर्जनसंसर्गात् मानहानिः पदे पदे ।
पावको लोहसंगेन मुद्रगरैरभिताद्यते ॥

द्वौ अम्भसि निवेष्टव्यौ गले बद्ध्वा दृढां शिलाम् । धनवन्तम् अदातारम् दरिद्रं च अतपस्विनम् ॥
