The global climate is on the verge of broad-scale change that could last for a number of decades, shows a study by British scientists.

The change is linked to cooling of the Atlantic, and is likely to bring drier summers in Britain and Ireland.

The study, which appeared in the journal Nature, is based on observational evidence of the link between ocean circulation and the decadal variability of sea surface temperatures called the Atlantic Multi-decadal Oscillation (AMO).

“Sea-surface temperatures in the Atlantic vary between warm and cold over time-scales of many decades. These variations have been shown to influence temperature, rainfall, drought and even the frequency of hurricanes in many regions of the world,” said lead author Gerard McCarthy from the National Oceanography Centre (NOC).

These climatic phases are the result of the movement of heat northwards by a system of ocean currents. This movement of heat changes the temperature of the sea surface, which has a profound impact on climate on time-scales of 20-30 years.

The strength of ocean currents has been measured by a network of sensors, called the RAPID array, which have been collecting data on the flow rate of the Atlantic meridonal overturning circulation (AMOC) for a decade. The authors used 100 years of sea level data, maintained by the National Oceanography Centre’s permanent service for mean sea level.

“By reconstructing ocean circulation over the last 100 years from tide gauges that measure sea level at the coast, we have been able to show, for the first time, observational evidence of the link between ocean circulation and the AMO,” said co-author Ivan Haigh, lecturer in coastal oceanography at the University of Southampton.

Ahead of the royal couple’s arrival, External Affairs Ministry spokesperson Raveesh Kumar said climate change, Sustainable Development Goals (SDGs), economic cooperation, and other bilateral issues would also come up for discussion.

Bilateral trade between India and Britain stands at $12.19 billion. India is the third largest investor in Britain and the second largest international job creator in that country.

Britain is the third largest inward investor in India, with a cumulative equity investment of $24.37 billion for the period April 2000-June 2017

The Indian diaspora in UK is one of the largest ethnic minority communities in the country, with the 2011 census recording approximately 1.5 million people of Indian origin equating to almost 1.8 percent of the population and contributing 6 per cent of the country’s GDP.

This will be Prince Charles ‘s ninth visit to India. He had earlier visited India in 1975, 1980, 1991, 1992, 2002, 2006, 2010 and 2013. (IANS)

Delhi Smog: Smog turns Delhi into a gas chamber

Writers call to confront the smog.

New Delhi, Nov 8: When acclaimed novelist Amitav Ghosh was writing “The Great Derangement”, a work of nonfiction on the burning issue of climate change, many in literary circles asked him: “Why would you write about something so boring?”

Some two years down the line, as the eyes burn and lungs choke in the “gas chamber” that residents of Delhi find themselves in, his book is a fitting examination of the scale and dangers of climate change.

It was not just a few in literary circles who failed to recognise the problem of climate change; for most of us, it remained something vague. in an interview to this correspondent just ahead the launch of “The Great Derangement”, Ghosh had abruptly asked: “Did you notice the smog that had filled the air just before the onset of winter?”

“I think I did,” I replied. “Well what did you do about it,” he immediately retorted.

Ghosh’s book, however, was a timely response to climate change and deserved much more attention than what it received then.

“Are we deranged,” asks Ghosh in the book and argues that future generations may well think so. “How else to explain our imaginative failure in the face of global warming?” It was his first major book of nonfiction since “In an Antique Land”, and in its pages Ghosh examines our inability — at the level of literature, history and politics — to grasp the scale of climate change.

“In a substantially altered world, when sea-level rise has swallowed the Sundarbans and made cities like Kolkata, New York and Bangkok uninhabitable, when readers and museum-goers turn to the art and literature of our time, will they not look, first, and most urgently, for traces and portents of the altered world of their inheritance? And when they fail to find them, what should they — what can they — do other than to conclude that ours was a time when most forms of art and literature were drawn into the modes of concealment that prevented people from recognizing the realities of their plight? Quite possibly then, this era, which so congratulates itself on its self-awareness, will come to be known as the time of the Great Derangement,” he writes in the book.

Ghosh had added in the interview that, at first, his concerns were about the damage that we are doing to the environment — but climate change is something much bigger.

“When we are talking about environmental impacts, we are talking about specific ecological systems, about specific environments and the ways in which human beings have impacted them. But climate change is something much bigger.

“We are talking about an inter-connected earth’s system, which is changing in ways that after a certain point human beings can’t actually control what is going to happen and that seems to be a situation that we are already in. These changes are occurring in ways that we can no longer impact them. If you look around the world and see what writers are writing about, very few are actually confronting this issue,” he had said.

He also pointed out that, in his opinion, there were no simple or easy solutions.

“What has actually happened is that we have lost the tools, and the ways of thinking, which allow us to understand or even to register what is happening around us. Even if we sometimes find ourselves in the midst of some of these changes, either we are unable to connect it to wider issues of climate change that are occurring or we are unable to think of it in an imaginative way.

“Something is happening, which is going to be, in the long run, catastrophic and yet we are unable to find some story for it,” he maintained.

The fundamental point that Ghosh raised in that interview was that artists, writers and filmmakers have not really given climate change the attention it needs.

He had said that he is “not in the business of finding solutions” but pointed out that one good way to finding a solution is to “understand the gravity and magnitude of the situation we are all in”.

Ghosh suggests that politics, much like literature, has become a matter of personal moral reckoning rather than an arena of collective action. But to limit fiction and politics to individual moral adventure comes at a great cost. The climate crisis asks us to imagine other forms of human existence — a task to which fiction, Ghosh argues, is the best suited of all cultural forms.

A few weeks from now, the smog may fade away and the perils of today may disappear both from the headlines and our minds. But Ghosh’s book will continue to serve as a great writer’s call to confront the most urgent task of our time.( IANS.)

He said technological advancement enables citizens to compare, discuss and analyse the credibility of news and the media should take extra caution to maintain its credibility.

According to him, reform in media can come from within and through introspection.

Observing most of the media discourse revolves around politics, Modi said the nation is made of over a billion people and the media should focus on the people and their achievements.

Citing the spread of mobile phones, Modi said citizen reporting is important in showcasing individual achievements and also helping in the aftermath of natural disasters.
