Volcanic carbon dioxide drove ancient global warming: Study

According to study conducted by researchers from University of Southampton, UK, extreme global warming event 56 million years ago was driven by massive carbon dioxide (CO2) emissions from volcanoes, during formation of North Atlantic Ocean.

They had used combination of new geochemical measurements and novel global climate modelling to show that Palaeocene-Eocene Thermal Maximum (PETM) was associated with rapid doubling of atmospheric CO2 in less than 25 thousand years because of CO2 emissions from volcanoes.

Key Facts

The PETM was most rapid and extreme natural global warming event of last 66 million years. It had lasted for around 150 thousand years and increased global temperatures by at least 5 degrees Celsius. Its period coincided with the formation of massive ‘flood basalts’ — large stretches of ocean floor coated in lava, resulting from of a series of huge eruptions.

Earlier it was suggested that PETM event was caused by injection of CO2 into ocean and atmosphere, but ultimate trigger source of CO2 was not known. Now researchers believe that, the CO2 was released during land drifts, separating Greenland from north-western Europe, thereby creating North Atlantic Ocean.

During this time, more than 10,000 petagrammes of CO2 was released predominantly from volcanic source. This is a vast amount of CO2, 30 times larger than all fossil fuels burned to date and equivalent to all current conventional and unconventional fossil fuel reserves.

National Nutrition Week: 1 to 7th September

The National Nutrition Week will be observed throughout the country from 1st to 7th September. The theme of for year 2017 is “Optimal Infant & Young Child Feeding Practices: Better Child Health“.

The objective of this event is to intensify awareness generation on importance of nutrition for health which has an overall impact on development, productivity, economic growth and ultimately National development.

Key Facts

During this week, Food and Nutrition Board of Ministry of Women & Child Development will coordinate with concerned Department of the State/UT Governments, NGOs, National Institutions and organize State/UT Level Workshops, Functionaries, Orientation Training of Fields Awareness Generation Camps, Community meetings.

Moreover, large numbers of awareness activities were organized at state, district and village levels. One day workshops to sensitize and for capacity building of State/Districts Level officers on importance of nutrition for better health will be also held.

Mini exhibition on nutrition displaying low cost nutritious diets and its importance for different age groups will also be organized at grassroots level. Besides, awareness generation on weight management and its importance through Body Mass Index (MBI) will also be held for adolescent boys and girls.

Importance of Nutrition

Nutrition is important survival, health and development issue for current and succeeding generations. All age groups represent National Economic Asset, so improving nutritional status of population is imperative for National Development.

Concerns

Under nutrition in young children continues to be a major public health problem in India. Child born underweight has impaired immune function and increased risk of diseases in their later life. Malnourished children tend to have lower IQ and impaired cognitive ability, which affects their school performance and productivity in later life. According to the NFHS4, there is no improvement in the nutritional status, especially among women and children even though level of underweight has decreased by 6.8%, stunting by 9.6%, anaemia by 11% as compared to NNHS-3 figures.
