A new study is blaming 2017’s unusually high number of hurricanes on the Atlantic Ocean’s rising surface temperatures. The report is one of the first to suggest that human-driven global warming is actually causing more hurricanes.
The study published in last week’s journal Science also predicts that as warming increases over the next 50 to 100 years, about two more hurricanes on average will form annually than we get now. In addition, those hurricanes will be stronger and wetter.
‘The new normal’
It’s a common refrain in these days to refer to outrageous weather events as “the new normal,” but those claims have been hard to quantify. Scientists do know the Earth is getting warmer, and evidence shows humans are contributing to the problem. But scientists have warned against attributing individual weather events to changes in climate, explaining that weather and climate are two different things.
But by any standard, 2017 was a tough year for people living on the Atlantic and Gulf coasts of the United States. Hurricane Harvey turned parts of coastal Texas and the city of Houston into a watery mess. And Hurricane Maria battered Puerto Rico so badly, the island only completed its power restoration projects in August of this year.
Using a new climate model, scientists at the National Oceanic and Atmospheric Administration began studying a particular swath of warming tropical Atlantic water near the equator. Speaking to VOA, author Hiro Murakami says water was especially warm last year and their model predicted about two more major hurricanes than usual. In reality, there were two more than average.
Get used to it, Murakami says. When this area of Atlantic water gets unusually warm, as it did in 2017, the U.S. should expect at least two extra hurricanes a year, he explains, adding that as the planet warms, that area of the Atlantic should heat up more and more often.
“Last year we saw six major hurricanes,” he said. “But these six could be eight major hurricanes in the future given the same summer conditions.”
That’s bad news for people who live near the coast and for the government officials who have to prepare for the massive storms.
Tom Delworth, another NOAA researcher who contributed to the study, says the new model can predict not only what’s going to happen this season, but also “100 years in the future.” And, he says, “50 to 60 years in advance, later in this century, the most intense storms will become even more intense category 4 and 5. They will be even stronger.”
Delworth and Murakami say their model is also applicable to typhoons in the Pacific, and warming waters there should have a similar effect in regions getting battered by those late summer storms.
Both researchers pointed to the unique value of the model in being able to predict hurricanes in the next week, the next month and the next century. However, they admit that while their model can fairly accurately predict what the hurricane seasons will look like in the months and years ahead, it can’t predict specific storms.
What good is it to know that more hurricanes are coming if we don’t know exactly where and when? Delworth says it can be incredibly empowering for first responders as they prepare for any given hurricane season. “Let’s have a lot of emergency supplies on hand,” he suggested, as an example, “because we think this is going to happen.”
He also says that every year, little by little, modelers and climate scientists are getting better and better at what they do. “That’s a very optimistic thing,” Delworth said. So, even as hurricanes get stronger and more numerous, forecasters may be able to get ahead of the game, or ahead of the storm, and ultimately save lives. (VOA)
Great historic events that have shaped the world and changed the outlines of countries are often not recorded in memory, or so we think. Wars made sure to destroy evidence and heritage, and the ones who survived told the tale of what really happened. Folklore, albeit through oral tradition kept alive many such stories, hidden in verse, limericks, and rhymes.
Ringa-ringa-roses, a common playtime rhyme among children across the world, is an example of folklore that has survived for many centuries. It tells the story of the The Great Plague of London which ravaged the city between 1665-1666.
The Plague broke out from improper disposal of garbage and poor sewage conditions. Fleas from the rats that lived in the sewers spread the disease that killed more than half of London's population. Many people fled from their homes as there was no medicine available for those who were infected.

It was around this time that masks began to be invented. The first masks were shaped like beaks, and were worn not to protect the wearer from the disease, but to the prevent them from being able to smell the decay and death around them, which they called 'miasma'. The beaks were filled with floral herbs that allowed doctors and nurses to tend to the sick without being reviled from the smell.
Children are often seen forming circles by holding hands and reciting loudly,
Pockets full of posies
We all fall down"

When the last line is sung, they break the circle and fall down. The roses and posies are believed to be the preferred fragrances inside the masks, and a single sneeze (a-tishoo) was enough to infect the one who was exposed to the disease. Consequently, they fell down, ill, and later died.
An alternative version of this rhyme is sung about the fall of Hiroshima and Nagasaki in the aftermath of World War II. The roses and posies are interchanged with geranium and uranium, to symbolise what was used in the atomic bomb. But this version is not as famous the original.

In modern times, many social movements aim to bring reform to the society we live in, on the basis of certain existing patterns. Patriarchy is something that many aim to cleanse our cultures of, to usher in the era of social and gender equality. Despite all these so-called movements, in southern India, certain societies that patronise matriarchy have existed since before India's independence. The Nairs and Ezhavas of Kerala, and Bunts and Billavas of Karnataka are matrilineal societies that continue to thrive in a patriarchal country.
Kerala remains separate from the rest of India in many ways. Be it literacy policy, form of government, or cultural practices, this state does not always conform to the ideal that India is known for. Even so with their social structure. Certain tribes have remained matrilineal, where the decision-making power rests with the eldest female of the family.

A male member, who is the close confidante of the matriarch is chosen. He plays a crucial role in representing the male members of his family, and his opinion is highly valued. He is called karavanan. The men reside in separate rooms or in separate houses, and do not interfere in the upbringing of children. Property is also passed down along the lineage of the eldest female. Among the Nairs, matriarchy is more prominently adhered to than the Ezhavas, who have some patrilocal connections.
In Karnataka, the Bunts and Billavas belong to the Tuluva ethnic group. They are also a predominantly matriarchal society, founded on the belief in a legend. Their matrilineal descent is known as Aliyasantana.
The story is told of a demon who threatened to destroy a kingdom if the king did not sacrifice his sons, but the king's sister comes forward to offer her children in sacrifice for the sake of the kingdom. The demon is touched and does not destroy the city. Since then, the kingdom, or the property is inherited through female lineage.

In the recent past, many of these matriarchal societies have been reduced to matrilineal societies by certain governmental laws. They fall under the patriarchal scheme of the rest of the state but have reserved the right to pass on property and heritage through the female line. In the North east of India, matriarchal dominance is far more resilient than the south.
