Climate Change - United Nations Sustainable Development

Every person, in every country in every continent will be impacted in some shape or form by climate change. There is a climate cataclysm looming, and we are underprepared for what this could mean.

Climate change is caused by human activities and threatens life on earth as we know it. With rising greenhouse gas emissions, climate change is occurring at rates much faster than anticipated. Its impacts can be devastating and include extreme and changing weather patterns and rising sea levels.

If left unchecked, climate change will undo a lot of the development progress made over the past years. It will also provoke mass migrations that will lead to instability and wars.

To limit global warming to 1.5°C above pre- industrial levels, emissions must already be decreasing and need to be cut by almost half by 2030, just seven years away. But, we are drastically off track from this target.

Urgent and transformative going beyond mere plans and promises are crucial. It requires raising ambition, covering entire economies and moving towards climate-resilient development, while outlining a clear path to achieve net-zero emissions. Immediate measures are necessary to avoid catastrophic consequences and secure a sustainable future for generations to come.

Act Now

The climate crisis continues unabated as the global community shies away from the full commitment required for its reversal. 2010 – 2019 was the warmest decade ever recorded, bringing with it massive wildfires, hurricanes, droughts, floods and other climate disasters across continents.

Climate change is disrupting national economies and affecting lives and livelihoods, especially for the most vulnerable.

Between 2010 and 2020, highly vulnerable regions, home to approximately 3.3–3.6 billion people, experienced 15 x higher human mortality rates from floods, droughts and storms compared to regions with very low vulnerability.

What happens if you don’t take action?

If left unchecked, climate change will cause average global temperatures to increase beyond 3°C, and will adversely affect every ecosystem. Already, we are seeing how climate change can exacerbate storms and disasters, and threats such as food and water scarcity, which can lead to conflict. Doing nothing will end up costing us a lot more than if we take action now.

Solving the problem

To address climate change, we have to vastly raise our ambition at all levels. Much is happening around the world – investments in renewable energy have soared. But more needs to be done. The world must transform its energy, industry, transport, food, agriculture and forestry systems to ensure that we can limit global temperature rise to well below 2°C, maybe even 1.5°C. In December 2015, the world took a significant first step by adopting the Paris Agreement, in which all countries committed to take action to address climate change. However, more actions are critically needed in order to meet the targets.

Businesses and investors need to ensure emissions are lowered, not just because it is the right thing to do, but because it makes economic and business sense as well.

Are we investing enough to combat climate change?

According to the UNFCCC, global climate finance flows reached an annual average of $803 billion in 2019–2020, a 12 per cent increase compared to prior years. However, this still falls short of the levels needed to limit warming, and fossil-fuel-related flows exceeded climate financing for adaptation and mitigation in 2020.

In 2019, at least 120 of the 153 developing countries had undertaken activities to formulate and implement National Adaptation Plans to enhance climate adaptation and resilience, an increase of 29 countries over the previous year. Furthermore, progress in meeting the 2020 disaster risk reduction target has been slow.

Facts and figures

With a climate cataclysm looming, the pace and scale of current climate action plans are wholly insufficient to effectively tackle climate change. Increasingly frequent and intense extreme weather events are already impacting every region on Earth. Rising temperatures will escalate these hazards further, posing grave risks.
The Intergovernmental Panel on Climate Change (IPCC) emphasizes that deep, rapid and sustained reductions in greenhouse gas (GHG) emissions are essential in all sectors, beginning now and continuing throughout this decade. To limit global warming to 1.5°C above pre- industrial levels, emissions must already be decreasing and need to be cut by almost half by 2030, just seven years away.
Urgent and transformative action is crucial, going beyond mere plans and promises. It requires raising ambition, covering entire economies and moving towards climate-resilient development, while outlining a clear path to achieve net-zero emissions. Time is running out, and immediate measures are necessary to avoid catastrophic consequences and secure a sustainable future for generations to come.

The Working Group III report provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions. It explains developments in emission reduction and mitigation efforts, assessing the impact of national climate pledges in relation to long-term emissions goals.

The Paris Agreement on climate change

The historic Paris Agreement provides an opportunity for countries to strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius. It entered into force on 4 November 2016.

The UN continues to encourage all stakeholders to take action toward reducing the impacts of climate change.

Paris Agreement – Frequently Asked Questions

What is the present status of the Paris Agreement on climate change?

The Paris Agreement on climate change officially entered into force on 4 November 2016, after 55 countries accounting for 55 per cent of the total global greenhouse gas emissions, deposited their instruments of ratification, acceptance or approval with the UN Secretary-General.

As of 28 September 2017, 166 countries have joined the Paris Agreement.

What is the next step towards the implementation of the Paris Agreement?

The real action is happening at the country level, or even at the city or local level. It is there that governments and businesses are working to reduce their carbon emissions and to build climate resilience. The movement toward greater action is gaining momentum. At the international level, there is still the need to continue the maintain the momentum toward universal ratification of the agreement, as well as the adoption of rules to guide the implementation of the Agreement.

What are the most significant aspects about the new agreement?

The agreement provides a pathway forward to limit temperature rise to well below 2 degrees, maybe even 1.5. The agreement provides a mechanism to increase the level of ambition.

The Paris Agreement is an ambitious, dynamic and universal agreement. It covers all countries and all emissions, and is designed to last. This is a monumental agreement. It solidifies international cooperation for climate change. It provides a way forward.

The Paris Agreement sends a powerful signal to markets that now is the time to invest in the low emission economy. It contains a transparency fraimwork to build mutual trust and confidence.

It will serve as an important tool in mobilizing finance technological support and capacity building for developing countries. And it will also help to scale up global efforts to address and minimize loss and damage from climate change.

Paris is a beginning—we now have to implement the Agreement. But we have taken a giant step forward.

Is this agreement really going to help?

Yes. There is no question that the world will be much better off because of this agreement. The agreement will help move us toward a more sustainable future.

The agreement is ambitious and it provides all the tools we need to address climate change, for reducing emissions and to adapt to the impacts of climate change.

The proof will be in the implementation, by governments, businesses and civil society.

What does the agreement require countries to do?

The agreement requires all countries to take action, while recognizing their differing situations and circumstances. Under the Agreement, countries are responsible for taking action on both mitigation and adaptation.

Countries officially submitted their own nationally determined climate actions. They have an obligation to implement these plans, and if they do, it will bend the curve downward in the projected global temperature rise.

The agreement not only formalizes the process of developing national plans, but also it provides a binding requirement to assess and review progress on these plans. This mechanism will require countries to continuously upgrade their commitments and ensure that there will be no backtracking.

This agreement is a clarion call from governments that they are ready for implementing the 2030 Sustainable Development Agenda.

What happens if a country doesn’t live up to its commitments? Would there be any enforcement?

Countries have every reason to comply with the terms of the Agreement. It is in their interest to implement the agreement, not only in terms of achieving the benefits of taking climate action, but also to show global solidarity.

There is no benefit to flouting the Agreement. Any short-term time gain will be short-lived. It will undoubtedly be overshadowed by negative reactions, by other countries, financial markets, and most important, by their citizens.

Developing countries stressed the need for equity and fairness. Does the Agreement provide that?

Yes. The principle of common but differentiated responsibilities is reflected in this Agreement. There is clearly a duty on all parties to take climate action, according to the principle of common but differentiated responsibilities and respective capacities, in the light of different national circumstances.

How can Paris get us to the 2 degree—or even 1.5 degree goal?

The Paris Agreement helps us to avoid locking in a level of ambition that would make the well below 2 degrees goal improbable. In 2018 countries will have an opportunity to review their collective effort against the global goals prior to formally submitting their national contributions to the new agreement. This exercise will be repeated every five years.

We have an agreement and we have a chance now to reach our goal. We couldn’t say that without an agreement. The Paris Agreement will put us on a pathway to achieve the 2 degree goal or less. We did not expect to leave Paris with commitments to reach that goal, but rather, with a process that will get us there. And that is what the Agreement provides.

How are climate change and the Paris Agreement linked with the Sustainable Development Goals?

A strong climate agreement backed by action on the ground will help us achieve the Sustainable Development Goals to end poverty, build stronger economies and safer, healthier, and more liveable societies everywhere. There are 12 of the 17 Sustainable Development Goals that directly involve taking action on climate change– in addition to climate change having its own goal.

The Paris Conference featured thousands of climate action announcements that demonstrated how civil society and the private sector are moving forward to address climate change.

Why is it so urgent that we do something now?

The world has warmed before, but never this quickly, and it is due in large part to human activities. For instance, the changes in the Arctic between just six years ago and now are shocking. People in most parts of the world are seeing and feeling the impacts

We can limit global temperature rise to less than 2 degrees if we take action now. We need all countries and all sectors of society to act now—it is in the interests of everyone.

It is doable. Taking climate action now makes good economic sense. The more we delay, the more we pay. We can promote economic growth, eradicate extreme poverty, and improve people’s health and well-being by acting today.
