Have We Broken the Jet Stream? Climate Change Fuels Chaos

Human-induced climate change has seriously disturbed the North Atlantic jet stream, a fast-moving ribbon of air high in the atmosphere, according to Madeleine Cuff’s recent research in New Scientist. This disturbance is increasingly being connected to extreme weather occurrences, such as the devastating floods that swept throughout Spain in November 2024.

What is the Jet Stream?

The jet stream is a powerful air current that influences weather patterns across the Northern Hemisphere. It is driven by temperature differences between the Arctic and the tropics. However, as the Arctic warms at a rate nearly four times faster than the global average, the temperature gradient weakens, causing the jet stream to slow down and meander. This alteration can lock weather systems in place, leading to prolonged extreme events such as heatwaves, droughts, and floods.

The Spanish Floods of November 2024

The record rainfall in Spain, which caused catastrophic floods and evacuated hundreds, is a clear example of the jet stream’s destabilisation. The slow-moving weather system that caused the rainfall was linked to a weaker and meandering jet stream, which kept the storm over the region for days.

The Spanish government declared a state of emergency as rivers overflowed and important infrastructure was damaged. The Spanish Meteorological Agency (AEMET) stated that the incident was “consistent with predictions of increased extreme weather due to climate change.”

Broader Implications

The impacts of a disrupted jet stream are not confined to Europe. North America, Asia, and other regions are also experiencing unusual and severe weather patterns. For instance:

Heatwaves: The Pacific Northwest saw record-breaking temperatures in the summer of 2024, attributed to a persistent high-pressure system linked to a meandering jet stream.
Droughts: Parts of the Horn of Africa are enduring prolonged dry spells, exacerbating food insecurity.
Winter Storms: The United States experienced intensified snowstorms in early 2025, also tied to jet stream anomalies.

What Can Be Done?

The destabilisation of the jet stream emphasises the importance of solving climate change. Limiting global warming to 1.5°C over pre-industrial levels, as stipulated in the Paris Agreement, is critical for preventing further disruptions. Experts advocate for the following measures:

Reducing Emissions: Rapid decarbonization of the global economy is essential to curbing Arctic warming.
Building Resilience: Investing in climate-resilient infrastructure can help communities adapt to extreme weather events.
Improving Forecasting: Enhanced understanding and monitoring of the jet stream can improve weather prediction and disaster preparedness.

Conclusion

The breaking of the jet stream is a powerful reminder of the interconnectedness of the planet’s systems and the profound consequences of human activity. As scientists continue to study these changes, it is clear that urgent action is needed to prevent further climate instability.

Should Thames Water be allowed to fail ?

By David Shepherd|2025-01-02T17:00:14+00:00December 31st, 2024|

Thames Water, the UK’s largest water provider with nearly 16 million users, is currently facing serious financial issues. Should it be allowed to fall into administration?

As of December 2024, the company’s debt exceeded £19 billion, raising questions about its operational viability and the likelihood for government intervention.

It recorded an operational deficit of £189 million in the first half of 2024, attributable to pollution penalties, consultancy payouts, and losses on inter-company loans. The corporation also faced exceptional charges of £465 million, including a £104 million provision for anticipated fines and a £40 million restructuring program.

This significant debt burden has stretched its financial resources, limiting its capacity to invest in critical infrastructure projects. Thomas Water has stated that it may run out of money by March 2025.

A 40% increase in pollution events has resulted in substantial fines, severely stressing the company’s budget. Thames Water was fined £18.2 million by Ofwat in December 2024 for violating dividend regulations on payments made in 2023 and 2024. Ofwat also stated that it will “claw back value” to recover £131 million of the payments.

Should Thames Water be allowed to fail ?

Thames Water is currently seeking permission for a potential £3 billion financial rescue package to address its current financial challenges – but will a new bail-out be merely “kicking the can down the road” ?

As an alternative, going into administration would support a full restructuring of the company’s operations, allowing a greater focus on efficiency and service quality without the immediate strain of debt commitments. This procedure then gets an opportunity to fix the root causes that have hampered the company’s performance over years of managed decline.

Administration allows the opportunity to reorganise or reduce the company’s significant debt, relieving financial pressures and creating a more sustainable economic model, thus increasing the company’s capacity to invest in vital infrastructure and environmental initiative.

A government-appointed administrator would verify that the company’s activities are in the public’s best interests, potentially leading to increased environmental compliance and customer service standards. This oversight has the potential to rebuild public trust while also ensuring regulatory compliance.

The administration of such a large utility may encourage a rethinking of the regulatory and ownership arrangements in the UK’s water industry, potentially leading to broader reforms that benefit both consumers and the environment. This may involve talks on alternative ownership arrangements, such as mutual or cooperative structures.

What are the potential downsides and risks ?

Going into administration, it will be critical to provide service continuity throughout: uninterrupted water supply and wastewater services during the transition period to preserve public health and safety.

The restructuring process will cause job uncertainty for Thames Water’s personnel, needing appropriate communication and support measures to address employee concerns.

To the financial markets, allowing a large utility to fall into administration might have a broader impact on investor confidence in the UK’s regulated industries, potentially influencing future investment and financing in the sector.

It will be critical to strike a compromise between Thames Water’s immediate requirements and the industry’s overall stability but the question remains: why shouldn’t Thames Water be allowed to fail and give us an opportunity to reset and renew, as a template for the UK water industry going forward, utilising a new mutual or cooperative model ?
