  • IPCC’s Climate Assessment Report

    The Geneva-based Intergovernmental Panel on Climate Change (IPCC) will release the first part of its Sixth Assessment Report, the periodic status check that has now become the most widely accepted scientific view of the state of the Earth’s climate.

    What is IPCC?

    • The IPCC, an intergovernmental body was established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP).
    • It was later endorsed by the UN General Assembly. Membership is open to all members of the WMO and UN.
    • The IPCC produces reports that contribute to the work of the UN Framework Convention on Climate Change (UNFCCC), the main international treaty on climate change.
    • The objective of the UNFCCC is to “stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic (human-induced) interference with the climate system.”
    • The IPCC’s Fifth Assessment Report was a critical scientific input into the UNFCCC’s Paris Agreement in 2015.

    What are IPCC reports?

    • IPCC reports cover the scientific, technical and socioeconomic information relevant to understanding the scientific basis of risk of human-induced climate change, its potential impacts and options for adaptation and mitigation.
    • The IPCC does not carry out original research, nor does it monitor climate or related phenomena itself.
    • Rather, it assesses published literature, including peer-reviewed and non-peer-reviewed sources.
    • However, the IPCC can be said to stimulate research in climate science.

    The Assessment Reports

    • The five previous assessment reports that have come out since the IPCC was established in 1988 have formed the basis of international climate change negotiations, and the actions of the governments.
    • Their value has been globally acknowledged, and the fourth assessment report, which came out in 2007, won the IPCC the Nobel Peace Prize.
    • Each of these voluminous reports, the last couple of them running into thousands of pages, have built upon the previous ones with updated knowledge and understanding of the climate system.
    • The reports have presented projections for temperature rise till 2100 under different scenarios and the kind of impacts that can be expected under each of these pathways.

    Key projections of the 6th Report

    Apart from incorporating the latest available scientific evidence, the Sixth Assessment Report is also attempting to provide more actionable information to help governments take policy decisions.

    • REGIONAL FOCUS: It is expected that this report would likely state what the scenarios for sea-level rise in the Bay of Bengal region is, not just what the average sea-level rise across the world is likely to be.
    • EXTREME EVENTS: There is expected to be bigger focus on extreme weather events, like the ones we have seen in the last few weeks.
    • CITIES: Densely populated mega-cities are supposed to be among the most vulnerable to impacts of climate change. The report is expected to present specific scenarios the climate change impacts on cities and large urban populations, and also implications for key infrastructure.
    • SYNERGIES: IPCC is expected to present a more integrated understanding of the situation, cross-link evidence and discuss trade-offs between different options or pathways, and also likely to cover social implications of climate change action by countries.

    Why it matters?

    • The IPCC assessment reports have been extremely influential in directing the dialogue and action on climate change.
    • The First Assessment Report led to the setting up of the UNFCCC, the umbrella agreement under which international negotiations on climate change take place every year.
    • The Second Assessment Report was the basis for the 1997 Kyoto Protocol that ran till last year, and the Fifth Assessment Report, which came out in 2014, guided the Paris Agreement.
    • The global climate architecture is now governed by the Paris Agreement, which replaced the Kyoto Protocol from this year.
    • There have been enough indications to suggest that global action was far below what was needed to keep the temperatures below 2°C, as mandated under the Paris Agreement.
    • In the immediate future, the IPCC report could serve as the most important warning towards the rapidly closing window of opportunity.

    Back2Basics: UNFCCC

    • The UNFCCC established an international environmental treaty to combat “dangerous human interference with the climate system”, in part by stabilizing greenhouse gas concentrations in the atmosphere.
    • It was signed by 154 states at the UN Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro from 3 to 14 June 1992.
  • Declaring a National Calamity

    Under the existing Scheme of State Disaster Response Fund / National Response Fund of the Ministry of Home Affairs, there is no provision to declare any disaster including flood as a National Calamity.

    How does the law define a disaster?

    • A natural disaster includes earthquake, flood, landslide, cyclone, tsunami, urban flood, heatwave; a man-made disaster can be nuclear, biological and chemical.
    • As per the Disaster Management Act, 2005, “disaster” means:
    1. A catastrophe, mishap, calamity or grave occurrence in any area, arising from natural or man-made causes, or
    2. It results in substantial loss of life or human suffering or damage to, and destruction of, property, or damage to, or degradation of, environment, and
    3. Damage is of such a nature or magnitude as to be beyond the coping capacity of the community of the affected area.

    How can any of these be classified as a national disaster?

    • There is no provision, executive or legal, to declare a natural calamity as a national calamity.
    • The existing guidelines of the State Disaster Response Fund (SDRF)/ National Disaster Response Fund (NDRF), do not contemplate declaring a disaster as a National Calamity.

    Has there ever been an attempt to define a national calamity?

    • In 2001, the National Committee under the chairmanship of the then PM was mandated to look into the parameters that should define a national calamity.
    • However, the committee did not suggest any fixed criterion.

    How, then, does the government classify disasters/calamities?

    • The 10th Finance Commission (1995-2000) examined a proposal that a disaster be termed “a national calamity of rarest severity” if it affects one-third of the population of a state.
    • The panel did not define a “calamity of rare severity” but stated that a calamity of rare severity would necessarily have to be adjudged on a case-to-case basis taking into account.

    What happens if a calamity is so declared?

    • When a calamity is declared to be of “rare severity/severe nature”, support to the state government is provided at the national level.
    • The Centre also considers additional assistance from the NDRF.
    • A Calamity Relief Fund (CRF) is set up, with the corpus shared 3:1 between Centre and state.
    • When resources in the CRF are inadequate, additional assistance is considered from the National Calamity Contingency Fund (NCCF), funded 100% by the Centre.
    • Relief in repayment of loans or for grant of fresh loans to the persons affected on concessional terms, too, are considered once a calamity is declared “severe”.
  • Air Quality Commission Bill, 2021

    The Lok Sabha has passed the Bill to formalize the Commission for Air Quality Management For National Capital Region and Adjoining Areas.

    Highlights of the AQC Bill

    • The AQC would be a ‘permanent’ body to address pollution in the National Capital Region Delhi and address sources of pollution in Delhi, Punjab, Rajasthan, Haryana and Uttar Pradesh.
    • The all-powerful body assumed several powers to coordinate action among States, levy fines — ranging up to ₹1 crore or five years of prison — to address air pollution.

    Key features

    • Over-riding powers: While the Central Pollution Control Board (CPCB) and its state branches have the powers to implement provisions of the Environment Protection Act for air, water and land pollution.
    • In case of dispute or a clash of jurisdictions, the AQC’s writ would prevail specific to matters concerning air pollution.
    • Chair: The body has a full-time chairperson and a range of members consisting of both representatives from several Ministries as well as independent experts and will have the final say on evolving policy and issuing directions.
    • Curb on stubble burning: the Commission may impose and collect environment compensation causing pollution by stubble burning.
    • No penalties to farmers: The Centre, facing flak earlier this year from farmers protesting the farm laws, had committed to removing a clause in the Air Commission Bill that would penalize farmers for burning stubble, an important contributor to noxious air quality.
  • Net-Zero Concept in Climate Change

    Independent charitable organization Oxfam has said that ‘net zero’ carbon targets that many countries have announced maybe a “dangerous distraction” from the priority of cutting carbon emissions.

    What does Net-Zero mean?

    • Net-zero, which is also referred to as carbon-neutrality, does not mean that a country would bring down its emissions to zero.
    • That would be gross-zero, which means reaching a state where there are no emissions at all, a scenario hard to comprehend.
    • Therefore, net-zero is a state in which a country’s emissions are compensated by absorption and removal of greenhouse gases from the atmosphere.

    Achieving net-zero targets

    • One way by which carbon can be absorbed is by creating carbon sinks.
    • Until recently, the Amazon rainforests in South America, which are the largest tropical forests in the world, were carbon sinks.
    • But eastern parts of these forests have started emitting CO2 instead of absorbing carbon emissions as a result of significant deforestation.

    What’s the difference between gross zero and net zero?

    • Given the impact that carbon emissions have on our planet, you might wonder why we aren’t aiming for zero, or gross zero, rather than net-zero.
    • Gross zero would mean stopping all emissions, which isn’t realistically attainable across all sectors of our lives and industry. Even with best efforts to reduce them, there will still be some emissions.
    • Net-zero looks at emissions overall, allowing for the removal of any unavoidable emissions, such as those from aviation or manufacturing.
    • Removing greenhouse gases could be via nature, as trees take carbon dioxide from the atmosphere, or through new technology or changing industrial processes.

    What is carbon negativity?

    • It is even possible for a country to have negative emissions if the absorption and removal exceed the actual emissions.
    • Bhutan has negative emissions because it absorbs more than it emits.

    Which countries have recently announced net-zero targets?

    • In 2019, the New Zealand government passed the Zero Carbon Act, which committed the country to zero carbon emissions by 2050 or sooner.
    • In the same year, the UK’s parliament passed legislation requiring the government to reduce the UK’s net emissions of greenhouse gases by 100 per cent relative to 1990 levels by the year 2050.
    • More recently, US announced that the country will cut its greenhouse gas emissions by at least 50 per cent below 2005 levels by 2030.
    • The European Union too, has a similar plan, called “Fit for 55”, the European Commission has asked all of its 27 member countries to cut emissions by 55 per cent below 1990 levels by 2030.
    • Last year, China also announced that it would become net-zero by the year 2060 and that it would not allow its emissions to peak beyond what they are in 2030.

    What does the Oxfam report say?

    • “Land-hungry ‘net zero’ schemes could force an 80 per cent rise in global food prices and more hunger while allowing rich nations and corporates to continue “dirty business-as-usual”.
    • The report says that if the challenge of change is tackled only by way of planting more trees, then about 1.6 billion hectares of new forests would be required to remove the world’s excess carbon by 2050.
    • Currently, countries’ plans to cut emissions will only lead to a one percent reduction by the year 2030.
    • Oxfam estimates that it could rise by 80 percent by the year 2050.
  • Why cloudbursts could become more frequent?

    Recently, cloudbursts have been reported from several places in J&K, Ladakh, Uttarakhand and Himachal Pradesh. A

    What is a Cloudburst?

    • Cloudbursts are short-duration, intense rainfall events over a small area.
    • According to the IMD, it is a weather phenomenon with unexpected precipitation exceeding 100mm/h over a geographical region of approximately 20-30 square km.

    What causes Cloudburst?

    • A study published last year studied the meteorological factors behind the cloudburst over the Kedarnath region.
    • They analyzed atmospheric pressure, temperature, rainfall, cloud water content, cloud fraction, cloud particle radius, cloud mixing ratio, total cloud cover, wind speed, wind direction, and relative humidity during the cloudburst, before as well as after the cloudburst.
    • The results showed that during the cloudburst, the relative humidity and cloud cover was at the maximum level with low temperature and slow winds.
    • It is expected that because of this situation a high amount of clouds may get condensed at a very rapid rate and result in a cloudburst.

    Impact of climate change

    • Several studies have shown that climate change will increase the frequency and intensity of cloudbursts in many cities across the globe.
    • As temperatures increase the atmosphere can hold more and more moisture and this moisture comes down as a short very intense rainfall for a short duration.
    • This results in flash floods in the mountainous areas and urban floods in the cities.
    • Also, there is evidence suggesting that globally short duration rainfall extremes are going to become more intense and frequent.

  • [pib] 14 Indian Tiger Reserves get Global CA/TS recognition

    The Environment Ministry has released the names of the 14 tiger reserves that had received the accreditation of the Global Conservation Assured|Tiger Standards (CA|TS), an accreditation tool agreed upon by tiger range countries.

    Conservation Assured | Tiger Standards (CA|TS)

    • CA|TS has been agreed upon as an accreditation tool by the global coalition of Tiger Range Countries (TRCs) and has been developed by tiger and protected area experts.
    • Officially launched in 2013, it sets minimum standards for effective management of target species and encourages the assessment of these standards in relevant conservation areas.
    • CA|TS is a set of criteria that allows tiger sites to check if their management will lead to successful tiger conservation.
    • The Global Tiger Forum (GTF), an international NGO working on tiger conservation, and World Wildlife Fund India are the two implementing partners of the National Tiger Conservation Authority for CATS assessment in India.

    Which are the 14 reserves?

    The 14 tiger reserves which have been accredited are:

    • Manas, Kaziranga and Orang in Assam,
    • Satpura, Kanha and Panna in Madhya Pradesh,
    • Pench in Maharashtra,
    • Valmiki Tiger Reserve in Bihar,
    • Dudhwa in Uttar Pradesh,
    • Sunderbans in West Bengal,
    • Parambikulam in Kerala,
    • Bandipur Tiger Reserve of Karnataka and
    • Mudumalai and Anamalai Tiger Reserve in Tamil Nadu

    Significance

    • CATS accreditation is a global recognition of good tiger governance.
    • This recognition means a lot in the context of adaptation to climate change, sustainability of ecosystem services, and safeguarding disruption of zoonotic cycles, through an umbrella species approach.
    • The aspects monitored for accreditation include the importance and status of a reserve, management, community participation, tourism, protection, habitat management, and tiger populations.

  • [pib] Centre launches Secured Logistics Document Exchange (SLDE) and GHG Calculator

    With an aim to further improve ease of doing business, Centre today launched the “Secured Logistics Document Exchange” along with a Calculator for Green House Gas Emissions.

    Secured Logistics Document Exchange (SLDE)

    • The SLDE platform is a solution to replace the present manual process of generation, exchange and compliance of logistics documents with a digitized, secure and seamless document exchange system.
    • It is set to improve logistics efficiency, reduce logistics cost, and promote multi-modality and sustainability in a big way.
    • This will enable generation, storage and interchange of logistics-related documents digitally using Aadhaar and blockchain-based security protocols for data security and authentication.
    • It will also provide a complete audit trail of document transfer, faster execution of transaction, lower cost of shipping and overall carbon footprint, easy verification of authenticity of documents, lowered risk of fraud, etc.
    • The proof of concept of the platform has been developed and executed with banks (ICICI, Axis Bank, State Bank of India and HDFC Bank) and stakeholders including freight forwarders, exporters, importers and vessel operators.

    Green House Gas (GHG) Emission Calculator

    • The GHG Calculator is an efficient, user-friendly tool and provides for calculating and comparing GHG emissions across different modes.
    • It allows for a commodity-wise comparison of GHG emissions and total cost of transportation, including their environmental cost, between movement by road and rail.
    • The tool is intended to facilitate appropriate modal choice for all concerned.

    Back2Basics: Green House Gases (GHGs)

    • A greenhouse gas (GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect.
    • The primary greenhouse gases in Earth’s atmosphere are water vapor (H 2O), carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2O), and ozone (O3).
    • Without greenhouse gases, the average temperature of Earth’s surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F).
    • The atmospheres of Venus, Mars, and Titan also contain greenhouse gases.
  • Thane Creek Flamingo Sanctuary proposed as Ramsar Site

    The Mumbai Metropolitan Region is likely to get its first Ramsar site at the Thane Creek Flamingo Sanctuary.

    Thane Creek Flamingo Sanctuary

    • The Maharashtra Government has declared the area along the western bank of Thane Creek as the “Thane Creek Flamingo Sanctuary” since 2015.
    • It is Maharashtra’s second marine sanctuary after the Malvan sanctuary.
    • It is recognized as an “Important Bird Area” by the Bombay Natural History Society.

    About Ramsar Convention

    • The Convention on Wetlands of International Importance (better known as the Ramsar Convention) is an international agreement promoting the conservation and wise use of wetlands.
    • It is the only global treaty to focus on a single ecosystem.
    • The convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
    • Traditionally viewed as a wasteland or breeding ground of disease, wetlands actually provide fresh water and food and serve as nature’s shock absorber.
    • Wetlands, critical for biodiversity, are disappearing rapidly, with recent estimates showing that 64% or more of the world’s wetlands have vanished since 1900.
    • Major changes in land use for agriculture and grazing, water diversion for dams and canals, and infrastructure development are considered to be some of the main causes of loss and degradation of wetlands.

    What does one mean by Ramsar Site?

    • A Ramsar Site is a wetland area designated to be of international importance under the Ramsar Convention.
    • It provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources.
  • What is Gross Environment Product?

    The Uttarakhand government recently announced it will initiate valuation of its natural resources in the form of ‘Gross Environment Product’ (GEP), said to be along the lines of Gross Domestic Product (GDP).

    Why such a move?

    • The idea of the valuation of the components of the environment is not new.
    • But it got impetus following rapid degradation of ecosystems, which led to adverse impacts on more than 60 percent of services we get from the ecosystems.

    What is Gross Environment Product (GEP)?

    • GEP is the measure of ecosystem services of any area.
    • It reflects the aggregated annual value of goods and services provided by ecosystems (forests, water bodies, oceans, etc.) to people in a given region, such as at district levels, state, and country.
    • It entails the establishment of a natural capital accounting framework by integrating ecological benefits into common measures of economic growth such as GDP.
    • It summarizes the value of ecosystem services in a single monetary metric.

    Evolution of GEP

    • The term “ecosystem services” was coined in 1981 to attract academics towards this aspect.
    • Ecosystem services represent the benefits humans get: Forests, lakes, and grasslands; timber and dyed; carbon sequestration and nutrient cycling; soil formation and productivity; and tourism.
    • The definition is still in the process of evolution. The concept received attention and now is part of global knowledge.

    Advantages offered

    • GEP can be applied as a scientific basis for Eco-Compensation and public financial transfers.
    • For example, Finance Commission’s revenue-sharing formula between the Union and the states including forest cover as a determining factor in a state’s share.
    • GEP can be applied to measure the status of ecosystem services, which is an important indicator of sustainable development.
    • It is also a critical indicator for measuring the progress of Eco-civilization.
    • Its implementation can help assess the impact of anthropological pressure on our ecosystem and natural resources- air, water, soil, forests.

    The Himalayan context

    • The Himalayas contribute substantially to the sustainability of the Gangetic Plains where 500 million people live.
    • The Union government incorporated the value of ecosystem services of its states in national accounting.
    • According to the recommendation of the 12th and 13th Finance Commissions, grants were transferred to forest-rich states in amounts corresponding to their forest covers.
    • However, considering only the forest cover in transferring funds to states is inadequate.
  • Species in news: Great Indian Bustards

    The Environment Ministry has informed the Parliament that there were no Great Indian Bustards (GIB) left in Kutch Bustard Sanctuary (KBS) in Gujarat’s Kutch district.

    Great Indian Bustards

    • GIBs are the largest among the four bustard species found in India, the other three being MacQueen’s bustard, lesser florican, and the Bengal florican.
    • GIBs’ historic range included much of the Indian sub-continent but it has now shrunken to just 10 percent of it. Among the heaviest birds with flight, GIBs prefer grasslands as their habitats.
    • GIBs are considered the flagship bird species of grassland.

    On the brink of extinction

    • The GIB population in India had fallen to just 150.
    • Pakistan is also believed to host a few GIBs and yet openly supports their hunting.

    Protection accorded

    • Birdlife International: uplisted from Endangered to Critically Endangered (2011)
    • Protection under CITES: Appendix I
    • IUCN status: Critically Endangered
    • Protection under Wildlife (Protection) Act: Schedule I

    Threats

    • Overhead power transmission
    • Poor vision: Due to their poor frontal vision, can’t detect powerlines in time and their weight makes in-flight quick maneuvers difficult.
    • Windmills: Coincidentally, Kutch and Thar desert are the places that have witnessed the creation of huge renewable energy infrastructure.
    • Noise pollution: Noise affects the mating and courtship practices of the GIB.
    • Changes in the landscape: by way of farmers cultivating their land, which otherwise used to remain fallow due to frequent droughts in Kutch.
    • Cultivation changes: Cultivation of cotton and wheat instead of pulses and fodder are also cited as reasons for falling GIB numbers.

    Supreme Court’s intervention

    • The Supreme Court has ordered that all overhead power transmission lines in core and potential GIB habitats in Rajasthan and Gujarat should be undergrounded.
    • The SC also formed a three-member committee to help power companies comply with the order.

    Conservation measures

    • In 2015, the Central government launched the GIB species recovery program.
    • Under the program, the WII and Rajasthan Forest departments have jointly set up conservation breeding centers where GIB eggs are harvested from the wild.
    • They have been incubated artificially and hatchlings raised in a controlled environment.
