Volcanic eruptions in India linked to dinosaur extinction
New York : Combined impacts of volcanic eruptions in India and an asteroid impact in Mexico brought about one of the Earth’s biggest mass extinctions that wiped out the dinosaurs 66 million years ago, confirms a new study.
“It’s quite likely both the volcanism and the asteroid were to blame for the ultimate mass extinction,” said one of the researchers, Andrea Dutton from the University of Florida.
“The Deccan Traps weakened the ecosystems before the asteroid slammed into the Earth — it’s consistent with an idea called the press-pulse hypothesis: a ‘one-two punch’ that proved devastating for life on Earth,” Dutton noted.
Located in India, the Deccan Traps are one of the largest volcanic provinces in the world.
Dutton and her colleagues at the University of Michigan utilised a new technique of analysis to reconstruct Antarctic Ocean temperatures that support the idea that the combined impacts of volcanic eruptions and an asteroid impact brought about the mass extinctions 66 million years ago.
Their research, published in the journal Nature Communications, used a recently developed technique called the carbonate clumped isotope paleothermometer to analyse the chemical composition of fossil shells in the Antarctic Ocean.
This analysis showed that ocean temperatures rose significantly.
The researchers linked these findings to two previously documented warming events that occurred near the end of the Cretaceous Period – one related to volcanic eruptions in India, and the other, tied to the impact of an asteroid or comet on the Yucatan Peninsula in Mexico.
To create their new temperature record, which spans 3.5 million years at the end of the Cretaceous and the start of the Paleogene Period, the researchers analysed the isotopic composition of 29 remarkably well-preserved shells of clam-like bivalves collected on Antarctica’s Seymour Island.
The data showed two significant temperature spikes.
The first corresponds to the eruption of the Deccan traps flood basalts. The other lines up exactly with the asteroid impact, which, in turn, may have sparked a renewed phase of volcanism in India.
Intriguingly, both events are associated with extinction events of nearly equal magnitude on Seymour Island, Antarctica, the study said.
Lucknow: Vishal Singh, a renowned social worker from Lucknow, also known as Foodman, has once again made India proud. He was honored by the Happy Hands Gloves Cooperative Limited Company in Korathai, Thailand, for his work with the Hunger Free World Mission.
The Hunger Free World Mission’s meeting was held in Korathai, Thailand, under Vishal Singh’s leadership. Representatives from several countries, including Mr. Raja Dwivedi (Managing Director of Happy Hands Gloves Limited), Thailand Coordinator Mr. Raja Mishra, and member Mr. Varun Singh, attended the event.
Under Vishal Singh’s leadership, the attendees took a pledge to work together toward creating a hunger-free world.
Speaking on the occasion, Vishal Singh explained that the main goal of the Hunger Free World Mission is social participation. He said the mission is not just about feeding people but also about meeting other basic needs of those who are struggling. The mission focuses on helping families of terminally ill patients in hospitals by providing food and shelter. It also works to fulfill essential needs like education, jobs, and care for the elderly.
For the last 16 years, the Vijay Sri Foundation has been providing free services, benefiting thousands of people. Vishal Singh highlighted that the mission aims to gain global recognition like other organizations such as WHO, WWF, and Red Cross, which work for social causes.
During this meeting, Vishal Singh was appointed as the Chairman of the Hunger Free World Mission by representatives from various countries. They also discussed holding regular meetings in different countries to push the mission forward.
Business tycoon Dr. Abhishek Verma has also supported this humanitarian mission, vowing to promote the idea of “Seva Parmo Dharma” (Service is the highest duty) worldwide. Vishal Singh praised him, stating that people like Dr .Abhishek Verma inspire others to work for the betterment of society.
Recently, Romania’s Ambassador, Mr . Daniela Sezonov Ţane, invited Vishal Singh to the Romanian Embassy in Delhi, where they discussed the mission in detail. Impressed by his humanitarian work, she honored Vishal Singh and invited him to Romania to take the mission forward .
Food man Vishal Singh has been serving the people of India for the past 16 years. Through the Vijay Sri Foundation, he provides free meals to cancer patients & their families ,shelter, and education for women & children along with running free old-age homes in Lucknow.
In addition to his humanitarian work, Vishal Singh also addresses issues like crime and corruption through his role as Chairman of Seva Path Media and Managing Director of Vijay Sri Foundation.
During the COVID-19 pandemic, Vishal Singh and his team worked tirelessly to provide food and help to the needy, including starving children, elderly citizens, and pregnant women. Despite contracting the virus himself, he continued to assist others after his recovery. He even created a life-saving oxygen regulator using household items, which was praised by doctors both in India and abroad.
In his address at the meeting, Vishal Singh spoke about his mission to create a hunger-free world. He pointed out that India’s large population, along with issues like unemployment and poverty, has caused the country to fall on the Hunger Index. He urged people to contribute just one handful of grains daily to help create a hunger-free world.
He concluded by saying that through social participation, we can empower the people around us, meet their basic needs, and work together to build a stronger, more prosperous, and developed society.
