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.

Thiruvananthapuram, Mar 12: In the wake of COVID-19 outbreak, Internet service providers in Kerala have agreed to step up the network capacity by 30 to 40 per cent of the present capacity to meet the demand, especially in view of the spurt in work-at-home mode.

"The decision was made at a meeting of representatives of various telecom service providers in Kerala circle and officials of the Telecommunication Department convened by the Secretary, Electronics and IT, following a direction by Chief Minister Pinarayi Vijayan to look into the issue," said a press release by the IT Department.

The decision will be beneficial for those working in IT institutions. The government has come out with a set of suggestions to avoid social gatherings at public places in view of coronavirus spread. Telecom service providers have assured the government that they are well equipped to face the current situation.

The major part of Internet consumption in Kerala is made available through local servers. Moreover, global Internet traffic is very low as compared to the overall consumption. So, increasing the capacity won't be difficult, service providers informed.

"Complaints regarding the low availability of the Internet due to the spurt in consumption of the Internet can be made to the service providers to their complaint redressal number or inform state government call centre (155300). But complaints regarding the insufficiency in the current network infrastructure should be strictly avoided," said the release.

The IT Department will also demand daily reports from various telecom service providers. By analysing these reports, steps for remedies will be taken after bringing the sudden increase in consumption to the service providers.

Paris, Jul 2: Several interacting exoplanets have already been spotted by satellites. But a new breakthrough has been achieved with, for the first time, the detection directly from the ground of an extrasolar system of this type.

An international collaboration including CNRS researchers has discovered an unusual planetary system, dubbed WASP-148, using the French instrument SOPHIE at the Observatoire de Haute-Provence (CNRS/Aix-Marseille Universite).

The scientists analysed the star's motion and concluded that it hosted two planets, WASP-148b and WASP-148c. The observations showed that the two planets were strongly interacting, which was confirmed from other data.

Whereas the first planet, WASP-148b, orbits its star in nearly nine days, the second one, WASP-148c, takes four times longer. This ratio between the orbital periods implies that the WASP-148 system is close to resonance, meaning that there is enhanced gravitational interaction between the two planets. And it turns out that the astronomers did indeed detect variations in the orbital periods of the planets.

While a single planet, uninfluenced by a second one, would move with a constant period, WASP-148b and WASP-148c undergo acceleration and deceleration that provides evidence of their interaction.

The study will shortly be published in the journal Astronomy & Astrophysics.

London, Feb 21: Scientists have discovered a new species of land snail, and have named it Craspedotropis Greta Thunberg in honour of the Swedish activist Greta Thunberg for her efforts to raise awareness about climate change.

According to the study, published in the Biodiversity Data Journal, the newly discovered species belongs to the so-called caenogastropods -- a group of land snails known to be sensitive to drought, temperature extremes, and forest degradation.

The scientists, including evolutionary ecologist Menno Schilthuizen from Naturalis Biodiversity Center in the Netherlands, said the snails were found very close to the research field station at Kuala Belalong Field Studies Centre in Brunei.

They added that the snails were discovered at the foot of a steep hill-slope, next to a river bank, foraging at night on the green leaves of understorey plants.

The effort aided by amateur scientist J.P. Lim, who found the first individual of the snail said, "Naming this snail after Greta Thunberg is our way of acknowledging that her generation will be responsible for fixing problems that they did not create."

"And it's a promise that people from all generations will join her to help," Lim said.

The researchers said they approached Thunberg who said that she would be "delighted" to have this species named after her.

The study work including, fieldwork, morphological study, and classification of identified specimen was carried out in a field centre with basic equipment and no internet access, the scientists said.

According to the study, the work was done by untrained ‘citizen scientists’ guided by experts, on a 10-day taxon expedition.

"While we are aware that this way of working has its limitations in terms of the quality of the output (for example, we were unable to perform dissections or to do extensive literature searches), the benefits include rapid species discovery and on-site processing of materials," the researchers wrote in the study.
