[In-depth] Climate Change: Causes, Impacts on India & World
Since August 2018, when Greta Thunberg initiated a protest in front of the Swedish Parliament, there have been hundreds of similar “climate strikes” across the world. This, along with extreme weather conditions like unpredictable monsoons, extended droughts and frequent cyclones are doing little to make the global leaders undertake measures to address this issue. India was ranked the seventh worst-hit country in 2019 in the Global Climate Risk Index 2021, released by the environmental think tank and sustainable development lobbyist Germanwatch. If the necessary steps are not taken soon, the decade we are going to embark on is going to be a lot more dangerous due to the rapid, out of control climate change.
What is climate change?
- Climate Change is a periodic modification of Earth’s climate brought about due to the changes in the atmosphere as well as the interactions between the atmosphere and various other geological, chemical, biological and geographical factors within the Earth’s system.
- Climate change can make weather patterns less predictable. These unforeseen weather patterns can make it difficult to maintain and grow crops, making agriculture-dependent countries like India vulnerable.
- It is also causing damaging weather events like more frequent and intense hurricanes, floods, cyclones, flooding etc.
- Due to the rising temperature caused by climate change, the ice in the polar regions is melting at an accelerated rate, causing sea levels to rise. This is damaging the coastlines due to the increased flooding and erosion.
- The cause of the current rapid climate change is due to human activities and threatening the very survival of humankind.
What are the factors that cause climate change?
Climate change is caused by natural factors as well as anthropogenic factors. However, anthropogenic factors create a higher impact on contemporary climate change.
There are numerous natural factors that cause the Earth’s climate to change. They affect the climate over a period of thousands to millions of years.
- The present-day continents were not the same prior to 200 million years.
- They have formed millions of years ago when the landmass began to drift apart due to plate displacement.
- This movement had an impact on climate change due to the change on the landmass’s physical features and position and the change in water bodies’ position like the change in the follow of ocean currents and winds.
- The drifting of the landmass is continued today. The Himalayan range is rising approximately 1 millimetre every year as the Indian landmass is moving towards the Asian landmass.
Variation of the Earth’s orbit:
- The Earth’s orbit has an impact on the sunlight’s seasonal distribution that is reaching the Earth’s surface.
- A slight change in the Earth’s orbit can lead to variation in distribution across the world.
- There are very few changes to the average sunshine. However, it causes a high impact on the geographical and seasonal distribution.
- There are three types of orbital variations – variations in Earth’s eccentricity, variations in the tilt angle of the Earth’s axis of rotation and precession of Earth’s axis.
- These together can cause Milankovitch cycles, which have a huge impact on climate and are well-known for their connection to the glacial and interglacial periods.
- The Intergovernmental Panel on Climate Change finding showed that the Milankovitch cycles had influenced the behaviour of ice formation
- Due to the change in the temperature in the core of the Earth, the mantle plumes and convection currents forced the Earth’s Plates to adjust leading to the rearrangement of the Earth Plate.
- This can influence the global and local patterns of climate and atmosphere.
- The oceans’ geometry is determined by the continents’ position. Therefore, the position of the continents influences the pattern of the ocean.
- The location of the sea also plays a crucial role in controlling the transfer of heat and moisture across the globe and determines the global climate.
- The recent example of the tectonic control on ocean circulation is the formation of the Isthmus of Panama about 5 million years ago, leading to the prevention of direct mixing of the Atlantic and Pacific oceans.
- When a volcano erupts, it emits gases and dust particles, causing a partial block of the Sunrays. This can lead to the cooling of the weather.
- Though the volcanic activities last only for a few days, the gases and ashes released by it can last for a long period, leading to it influencing climate patterns.
- Sulphur oxide emitted by the volcanic activities can combine with water to form tiny droplets of sulphuric acid. These droplets are so small that many of them can stay in the air for several years.
- Ocean current is one of the major components of the climate system.
- It is driven by horizontal winds causing the movement of the water against the sea surface.
- The temperature differences of the water influence the climate of the region.
Scientists, since the beginning of the 20th century, have studied the impact of climate change caused by human activities. Global warming, the long-term rise in the average temperature of the Earth’s climate system, is a major aspect of climate change. It is mainly a human-caused increase in global surface temperature. The anthropogenic factors causing climate change are as follows:
- The greenhouse gases absorb heat radiation from the sun. Following the initiation of the Industrial Revolution, the emission of greenhouse gases into the atmosphere has increased exponentially.
- This has led to more absorption and retaining the heat in the atmosphere. This resulted in an increase in Global Temperature.
- The greenhouse gases mostly do not absorb the solar radiation but absorb most of the infrared emitted by the Earth’s surface.
- The main greenhouse gases include
- water vapour (the majority of the GHG in the atmosphere but the impact is less)
- Carbon dioxide released due to natural and anthropogenic factors spends more time in the atmosphere, leading to an increase in its impact. There has been a 30% increase in the concentration of CO2 since the start of the industrial revolution. Apart from the industrial revolution, deforestation also contributes to the increase in the CO
- Chlorofluorocarbons, used for industrial purposes, especially in refrigerants and air conditioning, is a man-made compound regulated under the Montreal Protocol due to their adverse effects on the Ozone layers.
- Methane is released due to decomposition of organic matter. It is stronger than CO2 because of its capacity to absorb more heat.
- Nitrous oxide is produced by the agricultural sector, especially in the production and use of organic fertilizers and while burning fossil fuels.
Change in the land use pattern:
- Half of the land-use change is said to have happened during the industrial era.
- Most of the forests were replaced by agricultural cropping and grazing of lands.
- The increased albedo (reflectivity of an object in space) in the snow-covered high altitude regions due to deforestation led to the cooling of the planet’s surface. The lower the albedo, the more of the Sun’s radiation gets absorbed by the planet and the temperatures will rise. If the albedo is higher and the Earth is more reflective, the more of the radiation is returned to space, leading to the cooling of the planet.
- The tropical deforestation changes the evapotranspiration rates (the amount of water vapour put in the atmosphere through evaporation and transpiration from trees), causes desertification and affects soil moisture characteristics.
- From the satellite imagery, it is seen that the clearing of forest cover for agriculture and irrigated farming in arid and semi-arid lands can increase solar energy absorption and the amount of moisture evaporated into the atmosphere.
- Atmospheric aerosol can:
- scatter and absorb the solar and infrared radiation
- change microphysical and chemical properties of the clouds
- Solar radiation, when scattered, cools the planet. On the other hand, when the aerosols absorb solar radiation, it causes an increase in the temperature of the air instead of allowing the sunlight to be absorbed by the Earth’s surface.
- Aerosols can directly affect climate change by absorbing or reflecting solar radiation. They can also produce indirect effects by modifying the cloud’s formation and properties.
- They can even be transported thousands of kilometres away from its source through wind and upper-level circulation in the atmosphere.
- There are two types of aerosols – Natural aerosols and Anthropogenic aerosols.
- The sources of natural aerosols include volcanic eruptions (produces sulphate aerosols) and biogenic sources like planktons (can produce dimethyl sulphide).
- The anthropogenic aerosols include:
- The ammonia used for fertilizers or released by the burning of plants and other organic materials forms a major source for Nitrate aerosols.
- Burning of coal and oil produces sulphur dioxide that forms a major source of sulphate aerosols
- Burning of biomass can release a combination of organic droplets and soot particles.
- Industrial activities cause the release of wide-ranging aerosols into the atmosphere.
- Vehicle emissions can produce numerous pollutants that are aerosol from the beginning or becomes one due to chemical reactions in the atmosphere.
- It is found that the concentration of aerosols is about three times higher in the Northern Hemisphere than in the Southern Hemisphere, leading to Northern Hemisphere’s radiation concentration being 50% higher than that of the Southern Hemisphere.
What are the effects of climate change?
Global warming has caused a change in the climatic and weather conditions like change in the rainfall pattern, increased flooding, drought, heatwaves, etc. The planet’s ocean and glaciers have felt some significant changes. Oceans are currently warming and becoming more acidic. The ice caps are melting, causing the sea levels to rise. These changes are predicted to be more prominent in the coming decades, threatening our environment and existence. Some of the current impacts of rapid climate change are as follows:
A rise in atmospheric temperature:
- The greenhouse gases released due to human activities are increasing the temperature of the Earth.
- The last 6 years topped the list of hottest years ever recorded.
- The increase in temperature is the major cause of the current increase in heat-related deaths and illnesses, rise in sea levels and an increase in the intensity of natural disasters.
- The 20th century saw an increase in the Earth’s average temperature by 1°F. This is believed to be the fastest rise in a thousand years.
- Research estimates predict that if the GHGs are not reduced, the average surface temperature could increase to 3-5°F by the end of this century.
Change in landscapes:
- Increasing temperature and changing climate and weather patterns across the globe led to the shift of trees and plants towards Polar Regions and mountains.
- As the vegetation tries to adapt to climate change by moving towards colder regions, the animals that are dependent on them will be forced to follow them for survival. While some survive, many perish in the attempt.
- Other species like polar bears dependent on cold terrains will not have any habitat due to the melting of ice, causing a risk to their survival.
- Thus, the current hasty change in the landscape causes a considerable risk to the survival of many species, including the human population.
A risk to the ecosystem:
- An increase in the temperature across the globe is changing the weather and vegetation patterns, making the species to migrate to cooler areas for survival.
- This poses a threat to the survival of numerous species. It is projected that by 2050, one-fourth of the Earth’s species may become extinct if the current trend continues.
Rising sea levels:
- An increase in the temperature of the Earth leads to a rise in sea level due to the thermal expansion (a condition wherein the warm water takes up more area than cooler water). The melting of glaciers adds to this problem.
- The population living in under-lying areas, islands and coasts are threatened by the rising sea levels.
- It erodes shorelines, damage properties and destroys ecosystems like mangroves and wetlands that protect coasts from storms.
- In the last 100 years, the sea level has risen to 4-8 inches and will continue to rise between 4 and 36 inches in the next 100 years.
- The increase in the CO2 concentration in the atmosphere has increased the CO2 absorption in the ocean. This makes the ocean acidic.
- The increase in the acidification of the ocean can be harmful to many marine species like plankton, molluscs, etc. The corals are especially susceptible to this as they find it difficult to create and maintain the skeletal structures needed for their survival.
Increase in the risk of natural and manmade disasters:
- The moisture from land and water is rapidly evaporating due to the high atmospheric temperature.
- This causes drought. Those areas that are affected by drought are highly susceptible to the negative effects of flooding.
- As this current condition, the droughts may become more frequent and more severe. This may lead to distressing consequences for agriculture, water security, and health.
- Countries in Asia and Africa are already facing this phenomenon, with droughts becoming longer and more intense.
- The increased temperature is not only causing droughts but also increasing the cases of forest fires across the globe.
- Climate change is also causing increased and intensified hurricanes and tropical storms, causing a devastating impact on human societies and the environment.
- The cause of this is the rise in the ocean temperature as warm waters influence the hurricanes and tropical storms energies.
- The other factors that cause intensified hurricane and tropical storms are raising sea levels, disappearing wetlands and increased coastal development.
- The high temperature across the globe can pose health risks and deaths.
- The increased heat waves caused by climate change have led to the deaths of many globally.
- For instance, in 2003, the extreme heatwaves led to the death of more than 20,000 people in Europe and caused more than 1,500 deaths in India.
- Climate change increases the spreading of contagious diseases as the long-term warm weather allows disease-carrying insects, animals and microbes to survive longer.
- Disease and pests that were once confined to the tropics may find it habitable in the colder regions that were previously inhospitable.
- Currently, there is an increase in death due to extreme heat, natural disasters and diseases due to climate change.
- World Health Organisation estimates that between 2030 and 2050, climate change may cause approximately 250,000 additional deaths per year due to malnutrition, malaria, diarrhoea and extreme heat.
- It is estimated that if action is not taken to address the carbon emissions, climate change could cost about 5 to 20% of the annual global GDP.
- In contrast, the cost to lessen the most damaging effects of climate change is just 1% of the GDP.
- Climate change can alter shoreline habitats. This may lead to the need for relocation of ports and near-shore infrastructures and habitats, costing about millions of dollars.
- The increased hurricanes and other related natural disasters can bring forth extreme economic losses caused by damaged properties and infrastructures.
- Declining crop yields due to the lengthy droughts and high temperatures can lead to a risk of starvation of thousands of people.
- Coral reefs generate approximately $375 billion each year in goods and services. Their very survival is currently under threat.
Agriculture productivity and food security:
- The crop cultivation is dependent on solar radiation, favourable temperature and precipitation.
- Hence, agriculture has always been dependent on climate patterns.
- The current climate change
- has affected agricultural productivity, food supply and food security.
- These effects are biophysical, ecological and economic.
- They resulted in:
- Climate and agricultural zones are moving towards poles
- There is a change in the agricultural production pattern due to increased atmospheric temperature
- Agricultural productivity has increased due to the rise in CO2 in the atmosphere.
- Unpredictable precipitation patterns
- The vulnerability of the landless and the poor has increased.
How is climate change affecting India?
- One of the major areas that will be extremely vulnerable to climate change in the future is South Asia.
- India especially will be vulnerable to climate change due to its diverse terrain, rapid use of natural resources due to the current trend of precipitous urbanisation, industrialisation and economic growth.
- Currently, India, in its effort to protect its fast diminishing natural resources, is facing environmental and socio-economic challenges.
- Water and air quality are worsening each day due to environmental pollution.
- Those that are especially susceptible to climate change are the country’s coastal ecosystems, biodiversity and agricultural productivity.
- The natural disasters’ increasing frequency and intensity are causing negative effects to the already struggling Indian economy.
- The adverse effects of such disasters range from poverty, vulnerability to diseases, loss of income and livelihoods.
- According to the World Bank, an increase of 2°C in the world’s average temperature in the next few decades will only make India’s monsoon more unpredictable.
- The changing rain patterns in India are predicted to leave many areas flooded and others without water scarcity.
- More than 60% of India’s agriculture is dependent on rain and the majority of the population are dependent on the agriculture sector for survival. This makes India more vulnerable to climate change.
- It is estimated that by the 2050s, with a temperature increase of 2-2.5°C, water in the river basins of Indus, Ganges and Brahmaputra will be reduced. This may threaten the food security of about 63 million people.
- The poverty reduction rate will also be slowed down due to the rise in the atmospheric temperature.
- Poor will be more vulnerable to climate change since many of them are dependent on the rain-dependent agriculture.
- An increase of 2°C by the 2040s is going to affect crop production and will reduce the crop output by 12%, requiring more imports to meet the domestic demands.
- Furthermore, the decreasing availability of food can give rise to considerable health issues especially among women and children.
- The melting glaciers and loss of snow can pose a risk to reliable water resources in India.
- Main rivers like Ganges, Indus, and Brahmaputra mostly depend on snow and glacial meltwater. This makes them vulnerable to global warming.
- Climate change can further increase the risk of flooding of low areas and threatens agriculture.
- Impact on Drainage System: With the Indo-Gangetic Plains as its “breadbasket,” India withdraws 34% of its available water each year. Himalayan glaciers are melting faster and faster as temperatures rise and seasonal variability increases. If the rate rises, glacial lakes will burst their natural boundaries, causing flooding in river valleys fed by these glaciers, followed by reduced flows, resulting in water scarcity.
Government measures’ limitations:
- From the recent cases of natural disasters like the Chennai Floods, 2015, 2016 drought, 2019 Kerala floods, etc., it is evident that there are no adequate arrangements made to mitigate them.
- For instance, in the case of Uttarakhand or the Chennai rains, the arrangements weren’t adequate to allow the flow of rainwater due to the illegal constructions.
- From the 2016 drought, there were increased deaths, most of them were economically poor and the underprivileged.
- The government failed to ensure long-term mitigation and the big corporate houses that contribute to large-scale pollution of air and water escape with a mere “corporate social liability” clauses. These are some of the major causes of the devastating impact of these natural disasters.
- India does not have stringent laws to ensure protection against climate change.
- The authorities will not be prosecuted for their negligence of duty and the cases that manage to reach the Supreme Court through the public interest litigation were only able to bring about small changes in averting the future crisis.
- Each year, India is facing the negative impact of climate change and the government is taking measures to address it. Yet the measures taken will not be enough to solve the issue due to poor implementation and lack of accountability.
What are the efforts taken at the international level to combat climate change?
Intergovernmental Panel on Climate Change (IPCC)
- The World Meteorological Organisation (WMO) and the UN Environment Programme (UNEP) founded the IPCC to provide for a mechanism to study the effects of global warming at a governmental level.
- IPCC is a UN body that assesses the science related to climate change.
- It provides the policymakers with regular scientific assessments on climate change, its implications and potential future risks while also providing adaptation and mitigation options.
- It complements UNFCCC and vice versa.
United Nations Framework Convention on Climate Change (UNFCCC):
- It came to force on 21st March 1994.
- The 195 countries that have ratified it are called the Parties to the Convention.
- The UNFCC is a Rio Convention, one of the three adopted at the Rio Earth Summit in 1992. The others include the UN Convention on Biological Diversity and the UN Convention to Combat Desertification.
- The Joint Liaison Group was established to ensure cooperation among the three Conventions.
- Currently, it also consists of the Ramsar Convention on Wetlands.
- The ultimate aim of the Convention is to stabilize the greenhouse gas concentration “at a level that would prevent dangerous anthropogenic interference with the climate system”.
- It also aims to achieve the said level within a specific period so that the ecosystem is allowed to adapt naturally to climate change while also ensuring food security and sustainable economic development.
- Following its establishment, the COP1 (first Conference of Parties) was held in Berlin, COP2 was held in Geneva and the COP3 was held in Kyoto to adopt the “Kyoto Protocol” that ensures the implementation of the UNFCCC’s objective.
- Kyoto Protocols was adopted in Kyoto, Japan on 11th December 1997 and came to force on 16th February 2005
- Its signatories are committed towards the achievement of emission reduction targets.
- COP 7 held in Morocco in 2001 saw the adoption of the detailed rules for the implementation of the protocol. These are referred to as “Marrakesh Accords”.
- This protocol holds the developed countries are accountable for the current high levels of GHG emissions into the atmosphere due to their role in the industrial revolution.
- Kyoto Mechanism, also known as Flexible Mechanism, is defined under the Kyoto Protocol to lower the overall cost of achieving the emission targets. It includes Emission Trading, the Clean Development Mechanism and Joint Implementation.
- On December 2012, the Doha Amendment to the Kyoto Protocol was adopted. The changes made include:
- New commitments were made by Annex I Parties (developed nations and Economies in Transition) to be implemented between the period of 1st January 2013 and 31st December 2020.
- A revised list of GHG that is to be reported by the Parties during the second commitment period
- Amendments were made to update several articles of the Kyoto Protocol to be on par with the second commitment period.
- The Kyoto Protocol is a significant step towards the reduction of global emission regime that will allow the stabilisation of GHG emissions.
- Signed in 2016, it is considered to be the world’s first comprehensive climate agreement.
- It aims to:
- Keep the global temperature well below 2°C above preindustrial times and endeavour to limit them even more to 1.5°C.
- Strengthen the nations’ ability to combat the adverse impacts of climate change.
- The Paris Accord calls for a reduction of the GHGs emitted due to human activities equal to that of the trees, soil and oceans so that they can be absorbed naturally.
- As per the Agreement, each country’s contribution towards cutting emission must be reviewed every 5 years.
- It also states that rich countries must help the poorer nations by providing them with “Climate finances” to make them shift towards renewable energy usage.
- The agreement is binding in some elements like reporting requirements. Other elements of the agreement are non-binding like the emission targets of the individual nations.
- The Paris Agreement necessitates all Parties to put forth their best efforts through Nationally Determined Contributions (NDCs) and to strengthen these efforts in the future.
- This also includes the need for regular reporting emissions and implementation by the parties.
- India’s Intended Nationally Determined Contribution (INDC) includes the reduction in the intensity of its GDP by 33 to 35% by 2030 from 2005 level. Additionally, it has pledged to increase the share of non-fossil fuel-based electricity by 40% by 2030. It has also agreed to enhance its forest cover, which will absorb 2.5 to 3 billion tonnes of CO2 by 2030.
- Reducing Emissions from Deforestation and Forest Degradation (REDD+) is a mechanism developed by Parties of the UNFCCC.
- It creates financial value for the carbon stored in forests to offer incentives for the developing nations to reduce emissions from forested lands and invest in low-carbon paths.
- The developing nations will receive results-based payments for results-based actions.
- The REDD+ goes beyond simply deforestation and forest degradation by including the role of conservation, sustainable management of forests and enhancement of forest carbon stocks.
- It is estimated that the financial flows for the GHG emission reduction from REDD+ could reach up to $30 billion per year.
- This improved North-South flow of funds can ensure a significant reduction of carbon emissions and the promotion of inclusive development. It could also improve biodiversity conservation and secure vital ecosystem services.
- Forests are vital carbon sink and thus, it is vital to increase its resilience to climate change.
What are the measures taken by the Indian government to combat climate change?
- India is this fifth-largest emitter of GHG, accounting for approximately 5% of global emission.
- Emissions from India have increased by 65% during 1990-2005 and are estimated to increase by another 70% by 2020.
- As previously mentioned India is especially vulnerable to climate change because of the increased natural disasters, depleting natural resources and high dependence on agriculture and rain.
- Regardless of the resource limitations, India is taking numerous measures to adapt and mitigate climate change by increasing energy efficiency, promoting circular economic model, promoting the use of renewable energy
- India is among the few countries that have increased the Clean Energy Cess on coal.
- Clean Energy Fund worth approximately $3 billion is used to promote the use of clean technologies.
- The government is also increasing the investments for afforestation to increase the carbon sink.
- India has set a target of 33% of its geographical area under forest cover. According to the biennial State of India’s Forest Report 2019 (SoFR 2019), India’s total forest cover is 21.67% of the total geographical area of the country.
- India has allocated about $200 million for the National Adaptation Fund for Climate Change (NAFCC).
- It aims to support adaptation activities that can mitigate the adverse impact of climate change.
- The scheme’s activities are implemented in the project mode and the projects are related to adaptation in sectors like agriculture, animal husbandry, water, forestry, tourism, etc.
- Other initiatives include 100 smart cities, National Mission for Clean Ganga, National Air Quality Scheme, etc. Other major government measures are as follows:
National Action Plan on Climate Change (NAPCC)
- As a part of the NAPCC, the Indian government had launched 8 missions on focused areas. They are:
- National Solar Mission
- National Mission for Enhanced Energy Efficiency
- National Mission on Sustainable Habitat
- National Water Mission
- National Mission for Sustaining the Himalayan Ecosystem
- National Mission for a “Green India” Goals
- National Mission for Sustainable Agriculture
- National Mission on Strategic Knowledge for Climate Change
National Action Programme to Combat Desertification:
- India is one of the parties of UNCCD.
- The Ministry of Environment, Forest and Climate Change is the National Coordination Agency for the implementation of the UNCCD at the national level.
- India has framed the 20-year comprehensive National Action Programme (NAP) to address the problem of desertification within the nation. The objectives include:
- Drought management, preparedness, and mitigation
- Development based on a community approach
- Promote the improvement of local communities’ quality of life
- Promote awareness
- Promote suitable research and development initiatives and interventions.
- Promoting self-governance to empower local communities so that they can deal with issues pertaining to climate change.
India in the international forums on climate change:
- India is currently setting up voluntary targets in the international forums to commit itself to the mission to combat climate change. It is also playing a major role in climate change mitigation.
- India’s proactive role in mitigating climate change is due to the domestic compulsion of tackling issues like the need for poverty eradication, food and nutritional security, universalization of health and education, water security, sustainable energy, employment
- India is of the opinion that the developing countries’ need for inclusive growth, sustainable development, poverty eradication and universal access to energy must be made the fundamental differentiation between them and the developed nations. Currently, the Conventions recognise that the historical emissions of the developed nations as the basis for differentiation between the developed and developing nations.
What is stopping us from mitigating climate change?
The numerous decision-making barriers that currently exist are preventing the desired level of adaptation. The 5th Assessment Report of the IPCC has comprehensively identified the economic barriers that are preventing government decision on adaption to climate change. They are:
- Transitional costs: These are broadly divided into information and adjustment costs. The former refers to the costs that occur while acquiring information and the latter are the costs for replacing the long-lived capital.
- Market failures and missing markets: These include externalities, information asymmetries, and moral hazards. These cases are especially seen when one economic unit harms another unit. It also occurs when there aren’t sufficient incentives for the change.
- Behaviour obstacles to adaption: Irrational decisions, social norms, and cultural factors also pose as obstacles to adaption decision making.
- Ethical and distributional issues: These issues connect to the differences in vulnerability and adaptive capacity. Though sometimes a decision could ensure cost-effective and sustainable solutions, ethical constraints hinder these decisions.
- Coordination, government failures and politics: Though the governments must ensure the removal of the aforementioned barriers, they themselves face similar barriers like limited knowledge or resources. Also, coordination among various departments, though important, is highly difficult to obtain. Politics on whether or not climate change is real is also preventing the governments from undertaking adaption decision-making.
- Uncertainty is the largest barrier to adaptation as it expands to different dimensions like future developments of demographics, technologies and economics and the future of climate change.
Climate change is happening. This should be accepted and not politicised. International cooperation to address climate change is vital to mitigate the adverse impact. Additionally, mitigation must be complemented with climate change-related adaption since mitigation alone cannot address the adverse effects we are facing right now. An international level comprehensive plan of action is necessary for inclusive and sustainable growth of the global community.
Scientific consensus and public protests are doing little to motivate the governments’ policies towards climate change mitigation. Discuss. (250 Words)
Climate Change Performance Index 2022
The seventeenth edition of the Climate Change Performance Index 2022 was published on 10 November 2021. India ranked 10th while Denmark is the highest performing country in the index. The top ten nations in the index are– Denmark (4th position), Sweden (5th position), Norway (6th position), United Kingdom (7th position), Morocco (8th position), Chile (9th position), and India (10th position).
- The Climate Change Performance Index (CCPI) is an annual report released by Germanwatch, Climate Action Network (CAN) and New Climate Institute since 2005.
- CCPI is an independent tool that monitors the climate protection performance of about 60 countries and the European Union. These countries collectively produce around 90% of global greenhouse gas emissions.
- It seeks to improve transparency in international climate politics and enables a comparison of climate protection initiatives and progress achieved by individual nations.
- The report studies countries in 4 categories having 14 indicators – Greenhouse gas emissions (40% of total score), Renewable energy (20%), Energy use (20%) and Climate policy (20%).
