Volcanoes are a global phenomenon
Indian volcanoes are increasingly being identified as hotspots for the global phenomenon of global warming, with researchers claiming that some are producing more carbon dioxide than others.
A study of volcanoes around the world found that some of the world’s biggest, most active and potentially damaging ones are becoming more carbon intensive as they heat up, a phenomenon known as global warming.
This week, scientists in the US reported the first global temperature spike in more than half a century, a record that experts said could trigger global cooling and sea level rise.
The study by the US Geological Survey and the University of Texas at Austin found that the number of carbon dioxide emissions in the world was on the rise, but not for the same reasons it has been for the last 30 years, a trend that scientists have long suspected was the result of human-induced warming.
“The data suggests the rise in CO2 emissions has been the result both of an increase in global warming over the last decade and also the effects of natural and human-caused warming,” said the study, which was published in the journal Science.
The findings are likely to fuel a growing debate in the scientific community about the impact of climate change on the global economy and the ability of governments to adapt.
“Our results are a significant step in addressing some of our questions about how CO2 is being released and released to the atmosphere,” said Dr Paul Dettwyler, the study’s lead author and a geophysicist at the University at Buffalo.
“We’re finding some really interesting carbon dioxide spikes in the atmosphere that we’re not seeing on the ground.”
Volcanoes and their associated hot springs, springs, lakes and oceans are the source of a huge part of India’s annual monsoon, a freshwater supply for millions of people and the lifeblood of India.
A warmer climate means that India is more vulnerable to the impact on its agriculture and fisheries as temperatures increase, while the Himalayan region is being exposed to more frequent extreme weather events.
India’s annual rainfall, which varies from an average of more than 500 millimetres a year to less than 100mm, has fallen by more than 50% in the past two decades, and the country has already seen some of its worst droughts in decades.
“India is now in a really vulnerable position in terms of food security and the climate and our ability to deal with that,” said Daniel Peltier, a climate researcher at the Natural Resources Defense Council.
India, the world has the third-largest number of people on the planet, but only one in four is well-fed and well-equipped to cope with rising temperatures.
India has long been a hotbed of climate-related pollution, with the country’s pollution ranking as one of the worst in the developed world.
But the rise of global CO2 levels is likely to accelerate the damage, with climate scientists saying that the country will see more droughting and more severe storms.
“Global warming is causing more extreme weather, more extreme rainfall, more floods,” said Peltiers.
“There are some really big questions about India’s food security in the next few decades.”
