Scientists say that half of the world’s sandy beaches could disappear by the end of the century if climate change continues unchecked.

Researchers at the European Union’s Joint Research Center in Ispra, Italy, used satellite images to track the way beaches have changed over the past 30 years and simulated how global warming might affect them in the future.


“What we find is that by the end of the century around half of the beaches in the world will experience erosion that is more than 100 meters,” said Michalis Vousdoukas. “It’s likely that they will be lost.”

The study, published Monday in the journal Nature Climate Change, found that the extent to which beaches are at risk depends on how much average global temperatures increase by the year 2100. Greater temperature increases mean more sea level rise and more violent storms in some regions, causing more beaches to vanish beneath the waves.

“The projected shoreline changes will substantially impact the shape of the world’s coastline,”

more than a third of which is sandy beach, the authors wrote.

Beaches are valuable for recreation, tourism and wildlife, while also providing a natural barrier that protects coastal communities from waves and storms.

Many coastal areas, including beaches, are already heavily affected by human activity such as seashore construction and inland dams, which reduce the amount of silt flowing into oceans that’s crucial for beach recovery.

Some countries will be more affected than others, the researchers said. Gambia and Guinea-Bissau in West Africa could lose more than 60% of their beaches, while predictions for Iraq, Pakistan, the island of Jersey in the English Channel and the Pacific island of Palau are similarly dire.

Australia would be hardest-hit in terms of total beach coastline lost, with over 12,000 kilometers (7,500 miles) at risk. The United States, Canada, Mexico, China, Iran, Argentina and Chile would also lose thousands of kilometers (miles) of beach, according to the study.

Andres Payo, an expert on coastal hazards and resilience at the British Geological Survey, said that while the study’s methods were sound, its claims should be treated with caution.

“There are many assumptions and generalizations that could change the outcome of the analysis both qualitatively and quantitatively,”

said Payo, who wasn’t involved in the study.

However, Vousdoukas said the amount of beach loss estimated by his team was in fact “a bit conservative” and could be higher.

The group considered two different warming scenarios _ one in which average global temperatures rise by 2.4 degrees Celsius by the end of the century and another that predicts an increase twice as high. The Paris climate accord’s most ambitious target, of capping warming at 1.5 C, wasn’t considered because scientists consider it unlikely to be achieved, Vousdoukas said.

The study’s authors calculated that up to 40% of shoreline retreat could be prevented by reducing the greenhouse gas emissions that are driving climate change, but said that large and growing populations living along the coast will also need to be protected through other measures.

Citing the example of the Netherlands, which has battled the sea for centuries and even reclaimed substantial areas of low-lying land, the authors said “past experience has shown that effective site-specific coastal planning can mitigate beach erosion, eventually resulting in a stable coastline.” (VOA)

The aim of the book is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

By Siddhi Jain

Delhi-based author Pritisha Borthakur is set to release her new book, 'Puhor and Niyor's Mural of Family Stories'. The 1,404-word children's book was put together to address a new kind of societal debacle in the family system. The author says the aim is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

The author who named the book after her twin sons -- Puhor and Niyor -- is a parent who has seen and heard the tales of ridicule and discrimination suffered by many in India and beyond. She says the book is an artistic illustration for kids that details how different families can live and coexist. Whether it's children with two dads or two moms, children with a single dad or single mom, and even multiracial family units, Borthakur's book teaches love, understanding, and compassion towards unconventional families.

Beyond race, gender, color, and ethnicity which have formed the bases for discrimination since the beginning of time, this book aims to bring to light a largely ignored issue. For so long, single parents have been treated like a taboo without any attempt to understand their situations; no one really cares how or why one's marriage ended but just wants to treat single parents as villains simply for choosing happiness and loving their children.

Homosexual parents, a relatively new family system, is another form that has suffered hate and discrimination for many years. Pritisha emphasizes the need to understand that diversity in people and family is what makes the world beautiful and colourful. 'Puhor and Niyor's Mural of Family Stories' is a firm but compassionate statement against all forms of discrimination on the bases of sexual identity, gender, race, and even differences in background

Clean and maintained hands boost confidence in daily life activities.

If you feel that clean and well-groomed hands are just an essential prerequisite for women, you might like to think twice. Men should equally pay attention to their hands because our hand houses 1,500 bacteria living on each square centimeter of its skin. You can easily assume what havoc it can create in our body because in India we have the culture of eating with our hands and spaces beneath nails can become breeding heaven for germs. Moreover, clean and maintained hands boost confidence in their daily life activities. Therefore, it's important to keep your hands clean irrespective of your gender by washing or sanitizing at regular intervals. And, to keep them groomed, you don't have to visit a salon.

Rajesh U Pandya, Managing Director, KAI India, gives easy and completely doable tips to follow at home:

* Refrain from harsh soaps: You should be mindful of the soap you are using to wash your hands. Your soap can have a moisturizing element in it like aloe vera or shea butter. Ensure that you're washing your hands with normal water as hot water can make your hand's skin dry and scaly.

Bitcoin has become an essential crypto asset in modern portfolios and investment funds.

Bitcoin has become an essential crypto asset in modern portfolios and investment funds. The confidence generated in this cryptocurrency will depend a lot on the diversification that companies make in their balance sheets in Bitcoin and the increase of institutional investors that allocate a percentage of their funds in this crypto. American fund manager Cathie Wood makes some interesting predictions, both in the rise that the Bitcoin price will experience in the next 5 years, suggesting these institutional investors allocate 5% of their funds; this will help leverage the Bitcoin market.

Bitcoin will grow by a tenfold
