The relentless march of global warming has breached a major threshold, as confirmed by the EU’s climate service: for the first time, the average global temperature has exceeded 1.5°C over an entire year. This sobering milestone, initially aimed to be avoided in the Paris Agreement, signals a critical juncture in humanity’s battle against climate change. While this breach doesn’t constitute a direct violation of the accord, it underscores the pressing need for immediate and decisive action to curb carbon emissions.
Unprecedented Temperature Surge:
The period from February 2023 to January 2024 witnessed a staggering 1.52°C of warming, according to the EU’s Copernicus Climate Change Service. This unprecedented surge in temperatures far surpasses previous records, painting a grim picture of our planet’s trajectory if left unchecked.

Impacts of Exceeding 1.5°C:
The consequences of surpassing the 1.5°C mark are already evident in weather patterns: floods, droughts, heatwaves, and wildfires ravage communities worldwide. For business, managing risk becomes all the more challenging, as the frequency and severity of these weather events become more unpredictable; making planning and forecasting more difficult.
Political Backpedalling on Climate Commitments:
Against the backdrop of this, political shifts raise concerns. The Labour Party’s abandonment of its ambitious £28bn green investment plan, coupled with the Conservative Party’s reluctance to commit to essential targets and provide leadership, signify a worrying trend of scaling back climate pledges.
Tracking the Warming:
The warming trend extends beyond terrestrial realms; the world’s sea surface temperatures have soared to unprecedented levels.
Human activities, notably the continued burning of fossil fuels, remain the primary drivers of this relentless warming trend. While natural phenomena like El Niño provide temporary boosts to temperatures, the overarching influence of human-induced emissions cannot be ignored.
Despite the impending end of El Niño conditions, projections indicate a continued rise in temperatures, underscoring the imperative for sustained efforts to reduce carbon emissions.
Conclusion:
As the world grapples with the ramifications of surpassing the 1.5°C threshold, the urgency for decisive climate action needs to intensify. Solutions are available and small changes make a difference. While there are many challenges ahead, collective resolve to mitigate climate change offers a glimmer of hope; and business has a key part to play, ensuring action within an organisation and conducting essential due diligence on supply chains to ensure all aspects align to reduce carbon emissions and footprints.
With collective concerted efforts, humanity can steer away from the precipice of an irreversible climate catastrophe and forge a sustainable path forward. However, we cannot rely on policy makers to make this happen, it will fall on business and individuals to take action and seek to reduce risks and shape matters for the future.
