United Nations, Sept 24:Leaders from government, business, and civil society on Monday announced potentially far-reaching steps to confront climate change at the United Nations Secretary General's Climate Action Summit here on Monday.

As carbon pollution, temperatures, and climate destruction continue to rise, and public backlash mounts, the Summit offered a turning point from inertia into momentum, action, and global impact -- if everyone gets on board.

The UN estimates that the world would need to increase its efforts between three and five-fold to contain climate change to the levels dictated by science -- a 1.5 degrees Celsius rise at most -- and avoid escalating climate damage already taking place around the world.

With the Paris Agreement providing an open-door framework for countries to continuously ratchet up their positive actions, this Summit demonstrates how governments, businesses, and civilians around the world are rising to the challenge.

"The best science, according to the Intergovernmental Panel on Climate Change, tells us that any temperature rise above 1.5 degrees will lead to major and irreversible damage to the ecosystems that support us," UN Secretary General Antonio Guterres said.

"Science tells us that on our current path, we face at least 3 degrees Celsius of global heating by the end of the century.

"The climate emergency is a race we are losing, but it is a race we can win.

"This is not a climate talk summit. We have had enough talk," he added.

Guterres stressed that this was "not a climate negotiation summit" because "you don't negotiate with nature. This is a climate action summit".

"Governments are here to show you are serious about enhancing Nationally Determined Contributions under the Paris Agreement. Cities and businesses are here showing what leadership looks like, investing in a green future. Financial actors are here to scale-up action and deploy resources in fundamentally new and meaningful ways. Coalitions are here with partnerships and initiatives to move us closer to a resilient, carbon-neutral world by 2050."

The Summit, designed to showcase government, business, and civil society efforts to increase their commitments under the Paris Agreement and work toward reducing emissions to essentially zero by mid-century.

Many countries used the Summit to demonstrate next steps on how by 2020 they will update their Nationally Determined Contributions (NDCs) with the aim to collectively reduce emissions by at least 45 percent by 2030 and prepare national strategies to achieve carbon neutrality by mid-century.

Chile's President, Sebastian Pinera, announced the "Climate Ambition Alliance," which Chile hopes to build in the lead-up to COP25 in Santiago.

The Alliance brings together nations upscaling action by 2020, as well as those working towards achieving net zero CO2 emissions by 2050.

As many 59 nations have signaled their intention to submit an enhanced climate action plan (or NDC), and an additional nine nations have started an internal process to boost ambition and have this reflected in their national plans.

In terms of the 2050 group, 66 governments are joined by 10 regions, 102 cities, 93 businesses and 12 investors -- all committed to net zero CO2 emissions by 2050.

The UN Global Compact demonstrated that business is moving, as companies with a combined market capitalization of more than $2.3 trillion and annual direct emissions equivalent to 73 coal-fired power plants pledged to take action to align their businesses with science-based targets.

Many of the more than 70 key announcements showcase the concrete ways in which countries can better adapt to climate change and cut emissions while getting the necessary technical and financial support many of them need.

Getting out of coal is a priority.

The Powering Past Coal Alliance expanded to include 30 countries, 22 states or regions, and 31 corporations committed to stopping the building of new coal power plants in 2020 and rapidly transitioning to renewable energy.

The Asset Owner Alliance, a group of the world's largest pension funds and insurers, responsible for directing more than $2 trillion in investments, committed to transitioning to carbon-neutral investment portfolios by 2050.

The members of the Alliance will immediately start to engage with companies in which they are investing to ensure they decarbonize their business models.

Mumbai, Jul 3: In yet another move to keep Chinese technologies companies at bay, the Centre has cancelled the 4G upgradation tender for BSNL as it has decided to come up with fresh specifications for the upgrade process, sources said.

The Department of Telecommunications (DoT) is likely to issue a fresh tender in the next two weeks.

People in the know said that the fresh tender may not allow Chinese companies to participate and that the new tenders that will be floated in the next two weeks will emphasise on Make in India.

As the border tussle with China escalated last month and around 20 soldiers lost their lives, the government had last month asked both BSNL and MTNL not to use equipment of Chinese makers in their upgrading process to 4G facilities.

Huawei and ZTE are the major Chinese telecom equipment makers working with Indian telecom companies and they would be the hardest hit by the decision.

The impact may be felt in terms of the much-awaited 5G trials in the country. After much deliberation, the Centre last December decided to allow Huawei to take part in the 5G trials.

The cancellation of tender for BSNL's 4G upgradation comes after the Centre on Monday banned 59 Chinese apps including TikTok, WeChat and UC Browser.

A statement by the Ministry of Electronics and IT said that the decision was taken since "there is credible information that these apps are engaged in activities which are prejudicial to sovereignty and integrity of India, defence of India, security of state and public order".

Washington DC, Jun 8: Astronomers acting on a hunch have likely resolved a mystery about young, still-forming stars and regions rich in organic molecules closely surrounding some of them.

They used the National Science Foundation's Karl G Jansky Very Large Array (VLA) to reveal one such region that previously had eluded detection and that revelation answered a longstanding question.

The regions around the young protostars contain complex organic molecules which can further combine into prebiotic molecules that are the first steps on the road to life.

The regions, dubbed "hot corinos" by astronomers, are typically about the size of our solar system and are much warmer than their surroundings, though still quite cold by terrestrial standards.

The first hot corino was discovered in 2003 and only about a dozen have been found so far. Most of these are in binary systems, with two protostars forming simultaneously.

Astronomers have been puzzled by the fact that, in some of these binary systems, they found evidence for a hot corino around one of the protostars but not the other.

"Since the two stars are forming from the same molecular cloud and at the same time, it seemed strange that one would be surrounded by a dense region of complex organic molecules and the other wouldn't," said Cecilia Ceccarelli, of the Institute for Planetary Sciences and Astrophysics at the University of Grenoble (IPAG) in France.

The complex organic molecules were found by detecting specific radio frequencies, called spectral lines, emitted by the molecules. Those characteristic radio frequencies serve as "fingerprints" to identify the chemicals.

The astronomers noted that all the chemicals found in hot corinos had been found by detecting these "fingerprints" at radio frequencies corresponding to wavelengths of only a few millimetres.

"We know that dust blocks those wavelengths, so we decided to look for evidence of these chemicals at longer wavelengths that can easily pass through dust," said Claire Chandler of the National Radio Astronomy Observatory, and principal investigator on the project.

"It struck us that dust might be what was preventing us from detecting the molecules in one of the twin protostars," added Chandler.

The astronomers used the VLA to observe a pair of protostars called IRAS 4A, in a star-forming region about 1,000 light-years from Earth. They observed the pair at wavelengths of centimetres.

At those wavelengths, they sought radio emissions from methanol, CH3OH (wood alcohol, not for drinking). This was a pair in which one protostar clearly had a hot corino and the other did not, as seen using the much shorter wavelengths.

The result confirmed their hunch. "With the VLA, both protostars showed strong evidence of methanol surrounding them. This means that both protostars have hot corinos. The reason we did not see the one at shorter wavelengths was because of dust," said Marta de Simone, a graduate student at IPAG who led the data analysis for this object.

The astronomers cautioned that while both hot corinos now are known to contain methanol, there still may be some chemical differences between them. That, they said, can be settled by looking for other molecules at wavelengths not obscured by dust.

"This result tells us that using centimetre radio wavelengths is necessary to properly study hot corinos," Claudio Codella of Arcetri Astrophysical Observatory in Florence, Italy, said.

"In the future, planned new telescopes such as the next-generation VLA and SKA, will be very important to understanding these objects," added Codella.

While Google is still working on a coronavirus screening and tracking website, Microsoft Bing team has already launched a web portal for tracking COVID-19 infections worldwide.

The website, accessible at bing.com/covid, provides up-to-date infection statistics for each country.

The COVID-19 Tracker currently lists 168,835 as total confirmed cases, 84,558 active cases, 77,761 recovered cases and 6,516 deaths.

There are at least 3,244 confirmed cases of novel coronavirus in the US and at least 61 deaths.

"Lots of Bing folks worked (from home) this past week to create a mapping and authoritative news resource for COVID19 info," Michael Schechter, General Manager for Bing Growth and Distribution at Microsoft, was quoted as saying in a ZDNet report on Sunday.

An interactive map allows site visitors to click on the country to see the specific number of cases and related articles from a variety of publishers.

Data is being aggregated from sources like the World Health Organization (WHO), the US Centers for Disease Control and Prevention (CDC), and the European Centre for Disease Prevention and Control (ECDC).

Microsoft announced the website two days after US President Donald Trump said Google has begun working on COVID-19-related portal for US citizens.

Google's website is being built by Verily, a subsidiary of Alphabet focused on healthcare services.

"More than 1,700 engineers are currently working on the site", Trump said during a press briefing last week.

The tool will triage people who are concerned about their COVID-19 risk into testing sites based on guidance from public health officials and test availability.

Initially, there was some confusion on Google's coronavirus portal but the company later announced that it is "partnering with the US Government in developing a nationwide website that includes information about COVID-19 symptoms, risk, and testing information."
