If greenhouse gas emissions continue apace, Greenland and Antarctica’s melting ice sheets could together contribute more than 38 centimetre of global sea level rise by 2100, says a NASA-led study.

Results from this study that brought together more than 60 ice, ocean and atmosphere scientists from three dozen international institutions are in line with projections in the Intergovernmental Panel on Climate Change’s (IPCC) 2019 Special Report on Oceans and the Cryosphere.

Meltwater from ice sheets contribute about a third of the total global sea level rise.

The IPCC report projected that Greenland would contribute 8 to 27 cm to global sea level rise between 2000-2100 and Antarctica could contribute 3 to 28 cm.

These new results, published in a special issue of the journal The Cryosphere, come from the Ice Sheet Model Intercomparison Project (ISMIP6) led by NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

“One of the biggest uncertainties when it comes to how much sea level will rise in the future is how much the ice sheets will contribute,” said project leader and ice scientist Sophie Nowicki, now at the University at Buffalo, and formerly at NASA Goddard.

“And how much the ice sheets contribute is really dependent on what the climate will do.”

With warming air temperatures melting the surface of the ice sheet, and warming ocean temperatures causing ocean-terminating glaciers to retreat, Greenland’s ice sheet is a significant contributor to sea level rise.

The team investigated two different scenarios the IPCC has set for future climate to predict sea level rise between 2015 and 2100: one with carbon emissions increasing rapidly and another with lower emissions.

In the high emissions scenario, they found that the Greenland ice sheet would lead to an additional global sea level rise of about 9 cm by 2100.

In the lower emissions scenario, the loss from the ice sheet would raise global sea level by about 3 cm.

The team also analysed the Antarctic ice sheet to understand how much ice melt from future climate change would add to sea level rise, beyond what recent warming temperatures have already put in motion.

Ice loss from the Antarctic ice sheet is more difficult to predict: In the west, warm ocean currents erode the bottom of large floating ice shelves, causing loss; while the vast East Antarctic ice sheet can gain mass, as warmer temperatures cause increased snowfall.

The results point to a greater range of possibilities, from ice sheet change that decreases sea level by 7.8 cm, to increasing it by 30 cm by 2100, with different climate scenarios and climate model inputs.

The regional projections show the greatest loss in West Antarctica, responsible for up to 18 cm of sea level rise by 2100 in the warmest conditions, according to the research.

“The Amundsen Sea region in West Antarctica and Wilkes Land in East Antarctica are the two regions most sensitive to warming ocean temperatures and changing currents, and will continue to lose large amounts of ice,” said Heeleene Seroussi, an ice scientist at NASA’s Jet Propulsion Laboratory in Southern California.

Washington, Oct 15 (IANS) US President Donald Trump has slammed Facebook and Twitter for restricting the distribution of a New York Post article criticizing Democratic presidential nominee Joe Biden.

The New York Post published a series of stories on Wednesday citing emails, purportedly sent by Biden’s son.

The reports claimed it got those emails from Trump’s private lawyer, Rudy Giuliani, and former Trump adviser Steve Bannon, reports NPR.org.

Facebook limited the spread of the story which was liked, shared or commented on almost 600,000 times on Facebook, according to data from CrowdTangle.

In an unprecedented step, Twitter blocked users from posting pictures of the emails or links to two of the New York Post’s stories, citing its rules against sharing “content obtained through hacking that contains private information.”

Twitter said that the “images contained in the articles include personal and private information — like email addresses and phone numbers — which violate our rules”.

However, Twitter CEO Jack Dorsey acknowledged that the company’s communication about why it was blocking the articles “was not great”.

“Our communication around our actions on the @nypost article was not great. And blocking URL sharing via tweet or DM with zero context as to why we’re blocking: unacceptable”, he tweeted.

The action by Facebook and Twitter resulted in a political storm in the US.

Trump tweeted that it was “so terrible that Facebook and Twitter took down the story”.

Although Facebook did not remove it from its platform but limited its spread.

“REPEAL SECTION 230!!!” Trump said in a tweet.

Senator Josh Hawley of Missouri sent letters to Facebook and Twitter, pressing them on the decisions to reduce distribution and block the story.

Twitter and Facebook have been acting more aggressively to curb the spread of false claims and manipulation related to the election.

New Delhi, Oct 15 (IANS) Businesses will further accelerate the pace of their digital activities in 2021 by creating new-age apps and platforms and the world will see this battle ratcheting up in intensity in India led by Reliance Jio Platforms, a new report has said.

According to global market research firm Forrester, Covid-19 affected Asia Pacific first, and they expect the region will also emerge from the crisis first in 2021, before the US and Europe.

“APAC will see a platform surge. APAC is already home to some of the largest platforms in places like China and India. However, we will see this battle ratcheting up in intensity, especially in India,” said Ashutosh Sharma, VP, Research Director.

Reliance’s Jio Platforms has already blazed the trail with more than $20 billion investment in their digital business.

“They are simultaneously lining up more investments for their retail platform. Tata in India has thrown their hat in the ring with the announcement of their own super-app,” Sharma said in a statement on Wednesday.

With Paytm and Walmart’s Flipkart in the fray, India will see some serious competition among these platforms.

Targeting Google’s dominance in the app distribution space in India, leading digital payments platform Paytm last week set up a Rs 10 crore fund as equity investments for mini app developers in the country.

Paytm has also launched an Android Mini App Store to support local developers in the country.

On 5G, Forrester said the technology will finally make an impact and China will be its epicentre.

“In China, with heavy government support, rapid rollouts across the country, and evolution of supporting tech, 5G will find an ideal breeding ground for innovations across various verticals,” Sharma noted.

China’s experimentation and adoption of 5G-enabled business models and 5G-led innovation will offer valuable lessons to other countries and enterprises.

Values-focused firms will deliver higher profits than those focusing on profits alone.

“Brands can no longer work in shadows with a constant spotlight on each of their actions, statements, and associations across social media. They must show their explicit commitment to respect customers’ privacy, for example,” Sharma emphasized.

“They must tackle complex economic, environmental, and social challenges that impact all of us. They must do so with integrity, competence, and transparency to earn the trust and loyalty of these values-conscious consumers”.

The cybersecurity concerns will also dominate the agendas of businesses and governments alike.

“We will see increased adoption of Zero Trust and evolution of regulatory frameworks for data protection and privacy. Further, we expect firms to sharpen their focus on employee experience as they struggle to deal with people’s aspect of pandemic,” Sharma said.

Bengaluru, Oct 15 (IANS) Breach risk assessment firm FireCompass on Thursday unveiled a new Artificial Intelligence (AI)-powered platform that mimics thousands of hackers trying to break into an organisation, thus enabling the IT security teams launch continuous safe attacks to identify blind spots before hackers do.

Created by a team of serial cybersecurity entrepreneurs, the Continuous Automated Red Teaming (CART) platform is already in use by top companies, including Sprint (now a part of T-Mobile), Security Innovation and others, spanning multiple industries.

“Organisations typically conduct security testing only a few times a year on a partial list of online assets, excluding shadow IT unknown to security teams. Meanwhile, hackers are always attempting attacks on the entirety of their assets,” said Bikash Barai, Co-Founder of FireCompass.

“At FireCompass, our vision is to make the CART platform available to all so that organisations can discover and test all their assets at all times – just like real attackers do”.

The solution runs continuously without the need for software, hardware or additional employee resources.

It indexes the deep, dark and surface web using similar reconnaissance techniques as nation-state actors.

The platform automatically discovers an organisation’s ever-changing digital attack surface, including unknown exposed databases, cloud buckets, code leaks, exposed credentials, risky cloud assets and open ports, etc, the company said.

The attack engine then launches multi-stage attacks, which includes network attacks, application attacks and social engineering attacks, on the discovered digital surface to identify attack paths that are otherwise missed by conventional tools.

FireCompass is a software-as-a-service (SaaS) platform for Continuous Automated Red Teaming (CART) and Attack Surface Management (ASM).

Founded by industry veterans Bikash Barai, Nilanjan De and Priyanka Aash, FireCompass is backed by leading investors and venture capitalist funds.
