Context

The recent report of the Intergovernmental Panel on Climate Change (IPCC), the Working Group I contribution to the Sixth Assessment Report (AR6), titled ‘Climate Change 2021: The Physical Science Basis’, is the first of four that the Panel will issue over the next one and a half years.

The reports are eagerly awaited as they provide a summary assessment of all aspects of the challenge of global warming and past reports have heralded significant shifts in climate policy.

This particular report has added significance as it is the only one of the four of AR6 to be ready before the 26th Conference of the Parties (COP26) of the UN Framework Convention on Climate Change to be held in Glasgow in November.

Findings of the report

A significant section of the report reinforces what is already well known, though, importantly, with updated numbers, higher accuracy and specific regional assessments, including South Asia.

  1. Global surface temperature is now higher by 1.07 C since the pre-industrial era.
  2. The impact of climate change on the atmosphere, oceans and land is unmistakably of human origin and this impact is picking up pace.
  3. It is a striking fact that there is no part of the inhabited world that is now untouched by the impact of global warming.
  4. Carbon dioxide is the dominant source of warming.
  5. Aerosols contribute to reducing the impact of warming by other greenhouse gases, by almost a third.
  6. Methane reduction, while needed overall, is particularly significant only as part of the endgame as the drastic reduction of aerosols actually leads to an increase in warming.

The value of equilibrium climate sensitivitythe measure of how a specified increase in carbon dioxide concentration translates into long-term surface temperature rise — is now pinned down to the range of 2.5C to 4.0 C, with a best estimate of 3 C, compared to the Fifth Assessment Report range of 1.5oC to 4.5oC.

With the inclusion of the Indian Institute of Tropical Meteorology’s Earth System Model among the climate models used in AR6, India too has joined the climate modelling fraternity.

The report projects an increase in climate extremes due to global warming, with heat waves, extreme rainfall events and occurrence of extreme sea levels all expected to intensify and be more frequent.

Restrict cumulative emissions

A major finding of the report is that air pollution reduction and steep climate change mitigation are not complementary goals but require independent efforts over the short and medium term.

This is particularly important as the claims of such a linkage have been used to argue that India, for instance, must cease the use of coal immediately, despite its continuing importance as the key element of the country’s energy security.

The report is clear that it is the cumulative emissions in reaching net zero that determine the temperature rise.

India’s Ministry for Environment, Forest and Climate Change was quick to note this point about net zero in a statement, adding that “historical cumulative emissions are the cause of the climate crisis that the world faces today.” It also noted that the “developed countries had usurped far more than their fair share of the global carbon budget.”

The limitations of the remaining carbon budget for 1.5C are so stringent — a mere 500 billion tonnes of carbon dioxide for an even chance of keeping to the limit — that they cannot be met by promises of net zero 30 years from now.

The report is indeed a “clarion call for developed countries to undertake immediate, deep emission cuts,” especially if they are not to deprive the rest of the world, barring China, of any hope of future development.

Developed countries must, in fact, reach net zero well before 2050.

Little cheer for Global South

However, the exposure of the misleading character of the net zero campaign can bring little cheer to the global South, for an equally disconcerting finding is that the world is set to cross the 1.5C limit within 10-15 years.

If deep emissions cuts by the three big emitters — the U.S., the European Union and China — are not forthcoming, even the prospect of a mild overshoot of the limit followed by a later decline is likely to be foregone.

After years of procrastination in real action, the constant shifting of goal posts to avoid immediate emissions reduction, and marking time with their obsession with Article 6 negotiations to pass the burden on to developing countries, the developed countries now have nowhere to hide.

Regrettably, India cannot save the world from the consequences of the neglect of those whose responsibility it was to lead in taking credible action.

India has contributed less than 5% of global cumulative emissions to date, with per capita annual emissions a third of the global average. India is also the only nation among the G20 with commitments under the Paris Agreement that are even 2oC warming-compatible.

India needs its development space urgently to cope with the future, one where global temperature increase may be closer to 2C.

With India’s annual emissions at 3 billion tonnes in carbon dioxide equivalent terms, even the impossible, such as the total cessation of emissions for the next 30 years, with others’ emissions remaining the same, will buy the world less than two years of additional time for meeting the Paris Agreement temperature goals.

The prospect of keeping almost a sixth of humanity in quasi-permanent deprivation for the rest of the century as a consequence cannot even be contemplated.

Focusing on definite cumulative emission targets keeping equity and historical responsibility in view, immediate emission reductions by the developed countries with phase-out dates for all fossil fuels, massive investment in new technologies and their deployment, and a serious push to the mobilisation of adequate climate finance is the need of the hour. This is the message that the IPCC report has sent to this year’s climate summit and the world.

  • The United Nations has shaped so much of global co-operation and regulation that we wouldn’t recognise our world today without the UN’s pervasive role in it. So many small details of our lives – such as postage and copyright laws – are subject to international co-operation nurtured by the UN.

    In its 75th year, however, the UN is in a difficult moment as the world faces climate crisis, a global pandemic, great power competition, trade wars, economic depression and a wider breakdown in international co-operation.

    Flags outside the UN building in Manhattan, New York.

    Still, the UN has faced tough times before – over many decades during the Cold War, the Security Council was crippled by deep tensions between the US and the Soviet Union. The UN is not as sidelined or divided today as it was then. However, as the relationship between China and the US sours, the achievements of global co-operation are being eroded.

    The way in which people speak about the UN often implies a level of coherence and bureaucratic independence that the UN rarely possesses. A failure of the UN is normally better understood as a failure of international co-operation.

    We see this recently in the UN’s inability to deal with crises from the ethnic cleansing of the Rohingya Muslims in Myanmar, to civil conflict in Syria, and the failure of the Security Council to adopt a COVID-19 resolution calling for ceasefires in conflict zones and a co-operative international response to the pandemic.

    The UN administration is not primarily to blame for these failures; rather, the problem is the great powers – in the case of COVID-19, China and the US – refusing to co-operate.

    Where states fail to agree, the UN is powerless to act.

    Marking the 75th anniversary of the official formation of the UN, when 50 founding nations signed the UN Charter on June 26, 1945, we look at some of its key triumphs and resounding failures.


    Five successes

    1. Peacekeeping

    The United Nations was created with the goal of being a collective security organisation. The UN Charter establishes that the use of force is only lawful either in self-defence or if authorised by the UN Security Council. The Security Council’s five permanent members, being China, US, UK, Russia and France, can veto any such resolution.

    The UN’s consistent role in seeking to manage conflict is one of its greatest successes.

    A key component of this role is peacekeeping. The UN under its second secretary-general, the Swedish statesman Dag Hammarskjöld – who was posthumously awarded the Nobel Peace prize after he died in a suspicious plane crash – created the concept of peacekeeping. Hammarskjöld was responding to the 1956 Suez Crisis, in which the US opposed the invasion of Egypt by its allies Israel, France and the UK.

    UN peacekeeping missions involve the use of impartial and armed UN forces, drawn from member states, to stabilise fragile situations. “The essence of peacekeeping is the use of soldiers as a catalyst for peace rather than as the instruments of war,” said then UN Secretary-General Javier Pérez de Cuéllar, when the forces won the 1988 Nobel Peace Prize following missions in conflict zones in the Middle East, Africa, Asia, Central America and Europe.

    However, peacekeeping also counts among the UN’s major failures.

    2. Law of the Sea

    Negotiated between 1973 and 1982, the UN Convention on the Law of the Sea (UNCLOS) set up the current international law of the seas. It defines states’ rights and creates concepts such as exclusive economic zones, as well as procedures for the settling of disputes, new arrangements for governing deep sea bed mining, and importantly, new provisions for the protection of marine resources and ocean conservation.

    Mostly, countries have abided by the convention. There are various disputes that China has over the East and South China Seas which present a conflict between power and law, in that although UNCLOS creates mechanisms for resolving disputes, a powerful state isn’t necessarily going to submit to those mechanisms.

    Secondly, on the conservation front, although UNCLOS is a huge step forward, it has failed to adequately protect oceans that are outside any state’s control. Ocean ecosystems have been dramatically transformed through overfishing. This is an ecological catastrophe that UNCLOS has slowed, but failed to address comprehensively.

    3. Decolonisation

    The idea of racial equality and of a people’s right to self-determination was discussed in the wake of World War I and rejected. After World War II, however, those principles were endorsed within the UN system, and the Trusteeship Council, which monitored the process of decolonisation, was one of the initial bodies of the UN.

    Although many national independence movements only won liberation through bloody conflicts, the UN has overseen a process of decolonisation that has transformed international politics. In 1945, around one third of the world’s population lived under colonial rule. Today, there are less than 2 million people living in colonies.

    When it comes to the world’s First Nations, however, the UN generally has done little to address their concerns, aside from the non-binding UN Declaration on the Rights of Indigenous Peoples of 2007.

    4. Human rights

    The Human Rights Declaration of 1948 for the first time set out fundamental human rights to be universally protected, recognising that the “inherent dignity and of the equal and inalienable rights of all members of the human family is the foundation of freedom, justice and peace in the world”.

    Since 1948, 10 human rights treaties have been adopted – including conventions on the rights of children and migrant workers, and against torture and discrimination based on gender and race – each monitored by its own committee of independent experts.

    The language of human rights has created a new framework for thinking about the relationship between the individual, the state and the international system. Although some people would prefer that political movements focus on ‘liberation’ rather than ‘rights’, the idea of human rights has made the individual person a focus of national and international attention.

    5. Free trade

    Depending on your politics, you might view the World Trade Organisation as a huge success, or a huge failure.

    The WTO creates a near-binding system of international trade law with a clear and efficient dispute resolution process.

    The majority Australian consensus is that the WTO is a success because it has been good for Australian famers especially, through its winding back of subsidies and tariffs.

    However, the WTO enabled an era of globalisation which is now politically controversial.

    Recently, the US has sought to disrupt the system. In addition to the trade war with China, the Trump Administration has also refused to appoint tribunal members to the WTO’s Appellate Body, so it has crippled the dispute resolution process. Of course, the Trump Administration is not the first to take issue with China’s trade strategies, which include subsidises for ‘State Owned Enterprises’ and demands that foreign firms transfer intellectual property in exchange for market access.

    The existence of the UN has created a forum where nations can discuss new problems, and climate change is one of them. The Intergovernmental Panel on Climate Change (IPCC) was set up in 1988 to assess climate science and provide policymakers with assessments and options. In 1992, the UN Framework Convention on Climate Change created a permanent forum for negotiations.

    However, despite an international scientific body in the IPCC, and 165 signatory nations to the climate treaty, global greenhouse gas emissions have continued to increase.

    Under the Paris Agreement, even if every country meets its greenhouse gas emission targets we are still on track for ‘dangerous warming’. Yet, no major country is even on track to meet its targets; while emissions will probably decline this year as a result of COVID-19, atmospheric concentrations of greenhouse gases will still increase.

    This illustrates a core conundrum of the UN in that it opens the possibility of global cooperation, but is unable to constrain states from pursuing their narrowly conceived self-interests. Deep co-operation remains challenging.

    Five failures of the UN

    1. Peacekeeping

    During the Bosnian War, Dutch peacekeeping forces stationed in the town of Srebrenica, declared a ‘safe area’ by the UN in 1993, failed in 1995 to stop the massacre of more than 8000 Muslim men and boys by Bosnian Serb forces. This is one of the most widely discussed examples of the failures of international peacekeeping operations.

    On the massacre’s 10th anniversary, then UN Secretary General Kofi Annan wrote that the UN had “made serious errors of judgement, rooted in a philosophy of impartiality”, contributing to a mass murder that would “haunt our history forever”.

    If you look at some of the other infamous failures of peacekeeping missions – in places such as Rwanda, Somalia and Angola – ­it is the limited powers given to peacekeeping operations that have resulted in those failures.

    2. The invasion of Iraq

    The invasion of Iraq by the US in 2003, which was unlawful and without Security Council authorisation, reflects the fact that the UN is has very limited capacity to constrain the actions of great powers.

    The Security Council designers created the veto power so that any of the five permanent members could reject a Council resolution, so in that way it is programmed to fail when a great power really wants to do something that the international community generally condemns.

    In the case of the Iraq invasion, the US didn’t veto a resolution, but rather sought authorisation that it did not get. The UN, if you go by the idea of collective security, should have responded by defending Iraq against this unlawful use of force.

    The invasion proved a humanitarian disaster with the loss of more than 400,000 lives, and many believe that it led to the emergence of the terrorist Islamic State.

    3. Refugee crises

    The UN brokered the 1951 Refugee Convention to address the plight of people displaced in Europe due to World War II; years later, the 1967 Protocol removed time and geographical restrictions so that the Convention can now apply universally (although many countries in Asia have refused to sign it, owing in part to its Eurocentric origins).

    Despite these treaties, and the work of the UN High Commission for Refugees, there is somewhere between 30 and 40 million refugees, many of them, such as many Palestinians, living for decades outside their homelands. This is in addition to more than 40 million people displaced within their own countries.

    While for a long time refugee numbers were reducing, in recent years, particularly driven by the Syrian conflict, there have been increases in the number of people being displaced.

    During the COVID-19 crisis, boatloads of Rohingya refugees were turned away by port after port.  This tragedy has echoes of pre-World War II when ships of Jewish refugees fleeing Nazi Germany were refused entry by multiple countries.

    And as a catastrophe of a different kind looms, there is no international framework in place for responding to people who will be displaced by rising seas and other effects of climate change.

    4. Conflicts without end

    Across the world, there is a shopping list of unresolved civil conflicts and disputed territories.

    Palestine and Kashmir are two of the longest-running failures of the UN to resolve disputed lands. More recent, ongoing conflicts include the civil wars in Syria and Yemen.

    The common denominator of unresolved conflicts is either division among the great powers, or a lack of international interest due to the geopolitical stakes not being sufficiently high.  For instance, the inaction during the Rwandan civil war in the 1990s was not due to a division among great powers, but rather a lack of political will to engage.

    In Syria, by contrast, Russia and the US have opposing interests and back opposing sides: Russia backs the government of the Syrian dictator Bashar al-Assad, whereas the US does not.

    5. Acting like it’s 1945

    The UN is increasingly out of step with the reality of geopolitics today.

    The permanent members of the Security Council reflect the division of power internationally at the end of World War II. The continuing exclusion of Germany, Japan, and rising powers such as India and Indonesia, reflects the failure to reflect the changing balance of power.

    Also, bodies such as the IMF and the World Bank, which are part of the UN system, continue to be dominated by the West. In response, China has created potential rival institutions such as the Asian Infrastructure Investment Bank.

    Western domination of UN institutions undermines their credibility. However, a more fundamental problem is that institutions designed in 1945 are a poor fit with the systemic global challenges – of which climate change is foremost –  that we face today.
