UN climate summit begins in Peru

Officials from over 190 nations, including India, on Monday converged here at the UN climate summit to negotiate on a new ambitious and binding deal to cut global carbon emissions, in the last chance to reach on a historic deal to be signed next year in Paris.
Negotiations have been ongoing for 20 years, as the UN continues to bring its member countries together to help curb the damaging effects of coal burning and petroleum use, among other sources of pollution.
During the 12—day summit in the Peruvian capital, countries will put forward what they plan to contribute to the 2015 pact in the form of Intended Nationally Determined Contributions (INDCs) by the first quarter of 2015, well in advance of the Paris conference in December.
The Lima conference needs to provide final clarity on what the INDCs need to contain, including for developing countries who are likely to have a range of options from, for example, sector—wide emission curbs to energy intensity goals.
Environment Minister Prakash Javadekar leads India’s 17-member delegation to negotiate terms for the final agreement to be signed in Paris, which will take effect in 2020.
Ahead of the summit, a report by UN Intergovernmental Panel on Climate Change warned that populous coastal cities Mumbai and Kolkata are most vulnerable to loss of life and properties due to flooding in the second half of the century.
“Never before have the risks of climate change been so obvious and the impacts so visible. Never before have we seen such a desire at all levels of society to take climate action,” said Christiana Figueres, Executive Secretary of the UN Climate Convention.
The UN report warned against extreme weather events like occurrence of heatwave, heavy precipitation, droughts, floods, cyclones and wildfire that cause damage to ecosystems and human systems in various regions.
It suggested that given the current levels of greenhouse gases in the atmosphere and top polluters’ expected emissions in the coming years, it may be impossible to stop the planet from warming to the breaking point of 2 degrees Celsius.

What are the Centre and States doing to curb climate change, asks NGT

‘There is a conflict of interest between the Central Government and various States and because of this an important plan like the NAPCC has failed to get implemented in its true letter and spirit’

The National Green Tribunal on Monday sought response from the Centre, States and Union Territories about the measures they have been adopting to check climate change and how the governments have implemented the National Action Plan on Climate Change (NAPCC).
A bench headed by NGT Chairperson Justice Swatanter Kumar issued notices to the Ministry of Environment and Forests (MoEF), Ministry of Power, Ministry of New and Renewable Energy and several States.
The Bench was hearing a petition filed by advocate Gaurav Kumar Bansal, who has been raising various environmental concerns before the NGT. Mr. Bansal sought directions to place on record the relevant materials and documents relating to steps taken by the Centre and States to implement the NAPCC.
The plea said, “As a part of the international commitment to cut greenhouse gas emissions in India, the then Prime Minister on June 30, 2008, had released the NAPCC and said it reflects the importance the government attaches to mobilising the national energies to meet the challenges of climate change.”
In August 2009, the Central Government had directed all States and Union Territories to formulate individual state action plan on climate change guided by and consistent with the structure and strategies of the NAPCC, but nothing has been done in this direction, it said.
“The idea behind the individual State Action Plan on Climate Change (SAPCC) was that individual States and Union Territories must lay out sector-specific as well as cross sector time-bound priority actions along with indicative budgetary requirements, supplemented with details of necessary institutional and policy infrastructure for operationalisation of actions,” it said. The plea claimed that despite the Central Government’s direction, Maharashtra has not drafted its SAPCC. It further claimed that while preparing the SAPCCs, no States offered a clear, consistent and well-argued set of recommendations with either a vision or an action plan.
“There is a conflict of interest between the Central Government and various States of the country and because of this an important plan like the NAPCC has failed to get implemented in its true letter and spirit,” the plea said.
On January 30, 2010, the Joint Secretary, MoEF, in a letter to the Executive Secretary of United Nations Framework Convention on Climate Change had informed that India will try to reduce the emission intensity by 20-25 per cent by 2020 in comparison to the 2005 level, it said.

IISc: novel way to reduce cell damage found

Vanadia nanowires mimic an antioxidant enzyme produced by the body

Preliminary studies have shown a way to reduce cell damage and blunt the effect of one of the factors responsible for the onset of several diseases such as cancer, diabetes, cardiovascular diseases and ageing.
Reactive oxygen species, which are produced continuously in the body during cellular metabolism and responsible for cellular damage, are removed by naturally occurring antioxidants. However, the scavenging system fails when the amount of ROS produced is elevated. The most prevalent reactive oxygen species is hydrogen peroxide; excess amount of hydrogen peroxide can damage the cells the most.
By using vanadia nanowires, a team of researchers at the Indian Institute of Science (IISc), Bangalore was able to successfully remove any excess reactive oxygen species produced. The vanadia nanowires functionally mimic an antioxidant enzyme (glutathione peroxidase) produced by the body to scavenge hydrogen peroxide. Glutathione peroxidase is one of the two enzymes that control the level of hydrogen peroxide inside a cell.
The results of the study were published recently in the journal Nature Communications.
Unlike the nano form, the bulk, foam and complex forms of vanadium do the exact opposite. They produce more reactive oxygen species thereby negatively affecting the viability of cells.
In a nano form, vanadium is able to reduce hydrogen peroxide without changing the oxidation state of the metal, which is unusual for a metal ion.
“If the metal changes its oxidation state then vanadium can produce reactive oxygen species, which is what happens when vanadium is in a bulk and foam form,” said Prof. Govindasamy Mugesh from the Department of Inorganic and Physical Chemistry, IISc. He is one of the corresponding authors of the paper.
The nanowires proved successful as an ROS scavenger as they reacted with hydrogen peroxide to produce water. “Hydrogen peroxide reacts with vanadia on the surface of the nanowires, and once water is produced, the next molecule of hydrogen peroxide binds to the nanowire surface. So vanadia is able to continuously scavenge hydrogen peroxide without getting deactivated,” Prof. Mugesh said.
The efficiency of the nanowires as a scavenger was tested using hydrogen peroxide in a test tube and inside cells; cell lines were used for in vitro studies. “The scavenging is 100 per cent when hydrogen peroxide is used. But inside a cell, vanadia maintains optimum levels of reactive oxygen species,” Prof. Mugesh said.
The scavenging capacity inside a cell was significant even after 24 hours.
Apparently, the inability to completely remove hydrogen peroxide turns out to be beneficial.
“Optimum removal ensures that other biological functions remain unaffected by vanadia. If it scavenges all the hydrogen peroxide then it may block certain functions of the cell,” he explained.
According to Prof. Patrick D’Silva, Department of Biochemistry, IISc, the vanadia nanowires work in parallel to and in conjunction with the normal cellular antioxidant system. Prof. D’Silva is the other corresponding author of the paper.
Though the number of nanowires that get into a cell cannot be controlled, the amount of vanadia nanowires used is very small — in parts per million.
As vanadium is found in trace quantity in human body, its antioxidant potential inside cells was investigated. Since its harmful effects when in bulk and foam form were already known, the researchers studied its properties at nanoscale. “We tested a few other metal oxide nanoparticles but they did not show such antioxidant effect,” Prof. Mugesh said.
They have not studied how the nanowires get into a cell but know that they cannot stay inside a cell for over a day or two.
Its potential as an antioxidant will be known only when animal and human clinical trials are carried out.

GSAT-16 to be launched from French Guiana

GSAT-16, the communications satellite being put in orbit for ISRO from French Guiana in the wee hours of Friday, December 5, will significantly improve the national space capacity with 48 transponders.
The addition is important as GSAT-16 comes 11 months after the last Indian communication satellite GSAT-14 was flown in January this year. In fact, this launch was advanced by about six months to meet user needs, ISRO Chairman, K.Radhakrishnan, noted ahead of the launch.
This is also the highest number of transponders packed into an Indian spacecraft so far.

Include more adaptation efforts in Paris climate deal: India

With the ministerial-level talks to begin next week at the UN climate summit here, India today said its position remains very strong on the need for a balanced inclusion of adaptation efforts in the 2015 Paris agreement and less focus on mitigation.
Sushil Kumar, interim head of the Indian delegation at the talks, said the first two days of the 12-day conference are “off to a good start” with discussions on adaptation and finance underway.
He said that on Wednesday countries participated in sessions for the adaptation and finance groups.
“Developing countries are talking quite a bit about adaptation, but not developed countries,” he said.
Ministerial-level talks will begin next week which will be attended by Environment Minister Prakash Javedkar on December 7.
“The Indian position is to remain very strong on the need for a balanced inclusion of adaptation in the 2015 Paris agreement and less focus on mitigation efforts,” said Mr. Kumar.
The conference has to agree on a draft agreement which would form the cornerstone of a historic deal to be signed in Paris in December 2015 and take effect by 2020.
Kumar said that India will “need to bring [climate change issues] into development planning” and “disseminate whatever is in the IPCC report” at the state-level within India.
The state-level action plans are important because each will be have different concerns depending on whether it is a coastal, desert, or tropical climate.
Kumar said these tailored state plans are crucial for India to put together a “comprehensive and robust” Intended Nationally Determined Contribution (INDC).
A meeting of the Union Cabinet on Tuesday gave its approval to the negotiating position for the 20th Conference of Parties (COP—20) on climate change which is expected to conclude on December 12.
CoP-20 is expected to focus on the elements of 2015 Agreement and INDCs.
“The approach seeks to protect the interests of the country in climate change negotiations based on the principles of the United Nations Framework Convention on Climate Change (UNFCCC), and its Kyoto Protocol (KP). It would also enhance the solidarity among the developing countries on these issues,” a statement said.
So far 29 Indian states have submitted their action plans on adapting to and mitigating the effects of climate change with 21 state plans already approved.

Union Science and Technology Minister Harsh Vardhan on Tuesday signed a multilateral agreement admitting India’s participation in the development of the Thirty-Metre Telescope (TMT) in Hawaii.
The Cabinet rapidly cleared the project and India has agreed to spend Rs.1299.8 crore on it over the next decade. Besides learning about the universe, India will gain the technology to manufacture fine aspherical mirror segments from the California Institute of Technology (Caltech). This technology, say experts, will form the basis of the next generation of spy satellites.
TMT will contain 492 hexagonal mirror segments of 82 different kinds. These will behave like a single mirror with an aperture of 30-metre diameter. This large collecting area of 650 square metres is thrice as sensitive as the Hubble Space Telescope.
India’s role will primarily be to create the control systems and software that keep the mirrors aligned and collect the data.
The control system is an intricate process involving edge sensors that detect the mutual displacement of mirrors, actuators to correct their alignment, and the segment support assembly. These will be manufactured by General Optics (Asia) in Puducherry, Avasarala Technologies and Godrej in Bengaluru respectively.
G.C. Anupama of the Indian Institute of Astrophysics explained that India would also manufacture 100 aspherical mirror segments in Hoskote near Bengaluru. “These thin glass slabs made in Japan have minimal expansion when heated. We will apply a protective layer and a reflective coating using technology from Caltech,” she told The Hindu .
“Initially we will start off by producing two a year and after the technology transfer is complete, we will make one every fortnight,” she added. The telescope is expected to be ready by 2024.
Institutions from the United States, Canada, Japan and China are also participating in the construction of the world’s largest telescope on Mount Mauna Kea. This telescope, 4207 metres above sea level, may cost more than $1.47 billion.
