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 a few years away. But, we are drastically off track from this target.
The World Meteorological Organization (WMO) confirmed 2024 to be the hottest year on record, at approximately 1.55°C above pre-industrial levels. The WMO estimates an 80 per cent chance that at least one of the next five years will surpass 2024 as the hottest on record.
Extreme weather is intensifying, driving the highest climate-related displacement in 16 years and worsening food insecurity, economic losses and instability. Although one year above 1.5°C does not mean the Paris Agreement has been breached, it serves as a clarion call for increasing ambition and accelerating action in this critical decade, as current global efforts fall far short of what is needed.
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?
In 2009, developed countries agreed on mobilizing $100 billion a year for developing countries to adapt to climate change and cut greenhouse gas emissions. This included fund flowing through bilateral, regional and multilateral channels, as well private funds, through a variety of mechanisms, such as grants, loans and even insurance.
In 2022, developed countries met this goal for the first time, providing a total of $115.9 billion in climate finance for developing countries. However, only a small share of the total went to low-income countries and only about a quarter to Africa. Loans made up the largest funding category, mainly going to middle-income countries.
At COP29 in November 2024, governments agreed to set a New Collective Quantified Goal on climate finance of at least $300 billion per year by 2035, tripling the previously agreed target. In addition, they agreed to secure efforts of all public and private entities to scale up finance to developing countries to $1.3 trillion per year by 2035.

- According to the United Nations Environment Programme’s Emissions Gap Report 2024, global greenhouse gas emissions hit a record high of 57.1 gigatons of CO2 equivalent in 2023, up 1.3 per cent from 2022 and well above the 0.8 per cent annual average rise from 2010 to 2019.
- 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.
- 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.
13.1 Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries
13.2 Integrate climate change measures into national policies, strategies and planning
13.3 Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning
13.A Implement the commitment undertaken by developed-country parties to the United Nations Framework Convention on Climate Change to a goal of mobilizing jointly $100 billion annually by 2020 from all sources to address the needs of developing countries in the context of meaningful mitigation actions and transparency on implementation and fully operationalize the Green Climate Fund through its capitalization as soon as possible
13.B Promote mechanisms for raising capacity for effective climate change-related planning and management in least developed countries and small island developing States, including focusing on women, youth and local and marginalized communities
*Acknowledging that the United Nations Framework Convention on Climate Change is the primary international, intergovernmental forum for negotiating the global response to climate change.
The Paris Agreement on climate change
The UN continues to encourage all stakeholders to take action toward reducing the impacts of climate change.
