  • Sea levels are at the risk of rising due to rapid climate change
  • Sea levels are expected to rise twice as high by 2100
  • It is now high time we do something about the climate change

The sea level may rise twice as high by 2100 as previously estimated as a result of climate change, a new NASA study says.

According to the findings detailed in the journal Proceedings of the National Academy of Sciences, arise in sea level may increase by up to 65 centimetres in the next 80 years, enough to cause significant problems for coastal cities, Space.com reported on Friday.

“This is almost certainly a conservative estimate,” said Steve Nerem, Professor at the University of Colorado-Boulder, who led the NASA Sea Level Change team that conducted the study.

This acceleration has been driven mainly by increased ice melting in Greenland and Antarctica, the study said.

The findings are based on 25 years of NASA and European satellite data.

“Our extrapolation assumes that sea level continues to change in the future as it has over the last 25 years. Given the large changes we are seeing in the ice sheets today, that is not likely,” Nerem said in a statement.

Rising concentrations of greenhouse gases in Earth’s atmosphere increase the temperature of air and water, which causes sea level to rise in two ways.

First, warmer water expands, and this “thermal expansion” of the ocean has contributed about half of the seven centimetres of global mean sea level rise that has been observed over the past 25 years, Nerem said.

Second, the water from melting land ice flows into the ocean, which also increases sea level around the world. The rate of sea level rise has risen from about 2.5 millimetres per year in the 1990s to about 3.4 millimetres per year today, the researchers said.


NASA constantly monitors climate change and its effects.

These increases have been measured by satellite altimeters since 1992, including the TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 missions, which have been jointly managed by NASA, France’s Centre national d’etudes spatiales, the European Organisation for the Exploitation of Meteorological Satellites, and the US National Oceanic and Atmospheric Administration.

The researchers said that the speed of the acceleration can be affected by geological events such as volcanic eruptions or by climate patterns such as El Nino and La Nina.

They used climate models and other data sets to account for the volcanic effects and to determine the El Nino /La Nina effects, ultimately uncovering the underlying rate and acceleration of sea level rise. IANS

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.
