The world is on a collision course with climate disaster. A recent UN report paints a stark picture: we're highly likely to surpass the critical 1.5°C (2.7°F) warming limit within the next decade. Despite the promises made in the Paris Agreement, many countries are consistently falling short of their climate goals. This is a critical moment. Let's break down the details.
The report, issued by the UN Environment Programme (UNEP), highlights that current global climate commitments are projected to limit warming to 2.3°C to 2.5°C (4.1°F to 4.5°F) by the end of the century if all pledges are met. However, if we continue with existing policies, we're heading towards a scorching 2.8°C (5°F) increase. This is far from the necessary trajectory to avoid the worst impacts of climate change.
UNEP Executive Director Inger Andersen stated, "Nations have had three attempts to deliver promises made under the Paris Agreement, and each time they have landed off target." This raises a crucial question: why the repeated failures? What are the biggest obstacles?

Global emissions saw a 2.3% rise in 2024 compared to the previous year, with India, China, Russia, and Indonesia leading the increase. But here's where it gets controversial: the wealthy G20 nations are responsible for three-quarters of global emissions. Shockingly, the European Union was the only major polluter to reduce greenhouse gases last year.
Adding to the challenge, the United States, under former President Donald Trump, is moving away from its climate commitments, with plans to officially withdraw from the Paris Agreement. UNEP estimates that these actions could add an extra tenth of a degree of warming. The agency also emphasizes the need for the rest of the world to cut an additional two billion tonnes of carbon dioxide annually to offset the projected rise in US carbon pollution.
Every Fraction of a Degree Matters:
Scientists widely agree that exceeding the 1.5°C (2.7°F) threshold could trigger catastrophic consequences. At 1.4°C (2.5°F) above pre-industrial levels, we're already seeing devastating impacts on coral reefs, and the Amazon rainforest and ice sheets are at risk below 2°C (3.6°F).
Adelle Thomas, vice chair of a UN scientific panel, underscores the critical importance, stating, "Every tenth of a degree has ramifications on communities, on ecosystems around the world." This is especially true for vulnerable communities and ecosystems already experiencing the effects of climate change, such as heatwaves and sea level rise.
Only 60 parties to the Paris Agreement, representing 63% of global greenhouse gas emissions, had submitted or announced new mitigation targets for 2035 by the end-of-September deadline. The UN urges world leaders to take "decisive, accelerated" action to reduce emissions and minimize the overshoot of the 1.5°C (2.7°F) target.
UN Secretary-General Antonio Guterres acknowledged that exceeding the 1.5°C target is now inevitable, but emphasized that it is not a reason to give up. He stated that achieving the 1.5°C goal by the end of the century is still within reach, but only if we significantly increase our ambition.
