Month: April 2026

America’s Hottest March on Record: Anomaly or Warning?

March 2026 was not merely warmer than usual; it was historically and decisively so. Across the United States, temperatures did not just edge past previous records, they surpassed them by a margin so wide that it demands closer scrutiny. For the first time in recorded history, a single month exceeded the long-term average by more than 9 degrees Fahrenheit. That is not fluctuation. It is a signal. So the question becomes: when a record is broken so completely, is it still a record or is it evidence of a system that has fundamentally changed?

The data is striking. The previous benchmark for the warmest March, set in 2012, was eclipsed with ease. Ten states, including Arizona, California, Texas, and Colorado, recorded their hottest March on record. The American Southwest endured more than twelve days of record-shattering heat. Nationwide, nearly 19,800 daily temperature records were broken. Numbers of this scale do not suggest randomness, but acceleration. 

Yet temperature alone does not tell the full story. March was not only the warmest on record, it was also part of the driest January-through-March period observed in the contiguous United States since records began. Nearly 60 percent of the country is now experiencing drought conditions. The combination of heat and drought strain ecosystems, destabilize agriculture, and place extraordinary pressure on already fragile water systems. 

Consider Nebraska, where worsening drought conditions contributed to the largest wildfire in the state’s history: the Morrill Fire, which scorched more than 640,000 acres. Or perhaps take Florida, now enduring its worst drought in a quarter century, prompting water restrictions and heightening wildfire risk. These are manifestations of a broader pattern where extreme heat is intensifying existing vulnerabilities. 

This is most evident in the American West. The Colorado River, a critical water source for more than 40 million people across seven states, continues to face mounting stress. Reservoirs within the basin remain well below average levels. Lake Powell, the second-largest reservoir in the United States has already dropped more than ten feet this year alone, with projections indicating further decline in the months ahead.

This begs the question of what happens when a system designed for historical norms is confronted with conditions it was never built to withstand? Climate science offers an unsettling answer. According to the Fifth National Climate Assessment, human-driven climate change is increasing both the frequency and intensity of extreme heat events. Seasonal patterns are shifting, whereby winters are becoming shorter and milder while spring warmth is arriving earlier. Six of the ten most abnormally warm months in U.S. history have occurred within the past decade. The twelve-month period from April 2025 through March 2026 stands as the warmest on record for the continental United States. 

And yet, even as these records are being set, not only are the trends indicating a changing baseline, further escalation may already be underway. Forecasters are now closely monitoring the anticipated emergence of an El Niño event later this year, suggesting it could reach unusual strength. El Niño, a natural warming of Pacific Ocean surface temperatures, has long been known to elevate global temperatures. But in a world already warmed by greenhouse gas emissions, its effects may be amplified. 

Some scientists warn that a strong El Niño could push global temperatures to new heights into late 2026 and beyond. Others point to the possibility of longer-term shifts in climate patterns following particularly intense events; what was once considered temporary may, in effect, become the new normal.

This is where the distinction of weather and climate is important to establish. Weather is immediate, while climate is cumulative. A single hot month can be dismissed. A pattern of increasingly extreme months, occurring with greater frequency and intensity, cannot.

The implications extend well beyond temperature records. Water availability, agricultural stability, energy demand and disaster preparedness are influenced by these shifts. Legal and regulatory frameworks, many of which are grounded in historical data, may face increasing strain. 

Perhaps the most pressing question is not whether records will continue to be broken; the trajectory suggests they will. The more difficult question is how societies, institutions, and systems will respond when extremes cease to be exceptional. For now, the evidence points in a clear direction: the climate is changing and it is doing so at a pace that is no longer easy to ignore.

From Vindication to Exposure: Why the Gerry Adams Claim Collapsed

The recent discontinuance of civil proceedings against Gerry Adams in the High Court illustrates how procedural rules can shape litigation as decisively as statute or evidence. This is especially true in relation to costs, where a late-stage shift in risk can determine the outcome of a case regardless of its substantive merits.

Background of the case

The claimants were victims of IRA bombings, including the 1973 Old Bailey attack and later incidents in London Docklands and Manchester. Each sought nominal damages of £1, framing the case as a vindicatory exercise rather than a conventional claim for compensation.

Gerry Adams, former leader of Sinn Féin, has long denied IRA membership. The claimants alleged he bore personal responsibility for the attacks. The case proceeded to a two-week trial before Mr Justice Swift. Adams gave evidence over two days and was challenged on decades of material, including government documents and political statements. Counsel for Adams argued the claim rested on an “assortment of hearsay” and had been brought “several decades too late”.

Against that backdrop, the breadth of the evidence and the claimants’ aim of establishing responsibility for Troubles-era events raised a more fundamental procedural issue beyond a conventional civil claim.

Abuse of Process

It was in this context that the court intervened to consider whether the claim might amount to an abuse of process. Abuse of process is any use of litigation in a way that is “significantly different from the ordinary and proper use of the court process” The concern was not simply about the strength of the evidence, but about the function the proceedings were being asked to serve. Civil litigation is designed to determine defined disputes between parties on the basis of legally admissible evidence. It is not ordinarily a vehicle for a “collateral purpose” such as resolving broad questions of historical or political accountability.

By relying on extensive hearsay, historic allegations, and material not easily tested in the ordinary way, the claim risked inviting the court to conduct what was, in substance, a quasi-public inquiry into the Troubles. Although no final ruling on abuse of process was made, the judge’s decision to raise the issue at such a late stage fundamentally altered the nature of the litigation. What had been a question of liability became a question of whether the claim should have been brought at all – leading to potential costs implications for the claimants.

Costs Protection and the Risk of Adverse Costs

The claimants benefited from costs protection, most likely through qualified one-way costs shifting (QOCS), alongside any litigation funding arrangements in place. QOCS applies to claims for damages arising out of personal injury or death and operates to limit a claimant’s exposure to adverse costs. In practical terms, this means that, even if the claim fails, a defendant’s costs order is not enforceable beyond any damages recovered by the claimant. Here, where only nominal damages of £1 were sought, that protection would in effect operate as a near-complete shield against adverse costs liability.

However, that protection is not absolute. It can be disapplied where proceedings are struck out as an abuse of process. In such circumstances, the claimant loses the benefit of QOCS entirely, and any costs order becomes fully enforceable. If the court were to conclude that the proceedings constituted a misuse of its process, the claimants would therefore be exposed to the defendant’s costs in full.

As the claimants’ solicitors explained, the trial judge’s decision to raise this issue created “a real risk that the claimants… could face devastating personal liability for legal costs”. They added that the claimants had “no realistic choice” but to discontinue, given they were “faced with even a small risk of life-changing financial consequences”.

Conclusion

Ultimately, the case is a reminder that litigation is as much about risk management as it is about legal merits. Even a strongly motivated claim can become untenable if the cost position shifts. Here, once the possibility of losing costs protection arose, the position changed entirely. What began as a vindicatory claim became a question of exposure. Litigation strategy must be kept under constant review, not just considering the evidence, but in light of the evolving costs risk. Decisions to continue or discontinue are often driven less by the strength of the case than by the potential consequences of an adverse ruling.

A Legal Reset for AI Patents; The Turning Point for the AI and Software Patents Race in the UK

The boundaries of patent law are once again being tested by artificial intelligence. In a recent decision, the UK Intellectual Property Office (IPO) refused a patent application from AI music company DAACI for a system designed to automatically generate music based on an emotional brief. Despite the system’s ability to produce compositions with “audibly correct form,” the office concluded that the invention amounted to nothing more than a “program for a computer”, a category long excluded from patent protection under UK law.

The ruling highlights a growing legal tension: as generative AI systems increasingly blur the line between technical innovation and creative output, patent law is being forced to decide where software ends and invention begins.

At the centre of the dispute was a patent application filed by DAACI in March 2021 for a system designed to automatically generate musical compositions. The invention, described in patent GB 2605440A, aimed to create music that responds to an “emotional brief” provided by a user. In practice, the system would interpret narrative or emotional cues, such as tension, excitement, or melancholy and generate a composition intended to reflect those moods while maintaining what the company described as an “audibly correct form.”

The very nature of the invention; an AI system designed to automate the creative process, would become central to the legal challenge that followed. When the application came before the UK IPO, the key question was not whether the system could generate convincing music, but whether the underlying innovation amounted to a technical invention at all.

In assessing DAACI’s application, the UK IPO relied on the long-standing Aerotel framework for determining whether an invention falls within excluded subject matter such as a “computer program as such.” Under that approach, decision-makers first identify the invention’s contribution and then assess whether that contribution is technical in nature. Applying this reasoning, the hearing officer accepted that DAACI’s system contributed something new by automating musical composition in response to emotional prompts. However, he concluded that the problem being solved, producing aesthetically meaningful music, was ultimately creative rather than technical, meaning the invention remained within the exclusion.

However, just days after the DAACI decision was handed down, the Supreme Court ruled in Emotional Perception AI Ltd v Comptroller General of Patents that the Aerotel test should no longer be followed. Instead, UK law must align with the approach of the European Patent Office (EPO), particularly the Enlarged Board of Appeal’s decision in G1/19.

Under the new approach followed by the EPO, the first hurdle is relatively easy to clear. If an invention involves some form of technical system, such as software running on hardware, it will usually count as an “invention” in principle. But that does not mean it will receive a patent. The real test comes next, when examiners look closely at the invention’s features and ask a tougher question: which parts of this system actually represent a technical improvement? Only those technical elements are considered when deciding whether the invention is truly new and inventive compared to what already exists. This matters because, as AI systems become more sophisticated, whether an invention passes this test could determine which companies can claim ownership of the underlying technology, and ultimately shape who leads the next generation of AI-driven creativity.

Viewed through this updated lens, the reasoning in DAACI appears somewhat out of step with the direction of UK patent law. The new framework would focus more narrowly on whether the claimed system involved technical means and which elements of it possess genuine technical character. For AI-driven systems operating at the intersection of software and creativity, that shift could prove decisive.

The timing of the DAACI decision makes this tension particularly striking. The removal of the old Aerotel framework and the shift toward the EPO’s approach may make it easier for AI inventions to pass the first hurdle of patent eligibility. But that does not mean patents for generative AI will suddenly become commonplace. Instead, the battleground is likely to move deeper into the analysis, where companies must show that the technical machinery behind the AI, its architecture, training processes, or data processing methods, represents a genuine technological advance.

This shift could also change how AI developers approach patent strategy. Rather than emphasising the creative results produced by their systems, companies may increasingly frame their inventions around the technical processes that enable those results, for example; the way an algorithm processes input data, structures musical elements, or optimises the generation of compositions. In other words, the legal focus may move away from the music itself and toward the technical infrastructure that allows machines to create it.

If patents do begin to emerge around these kinds of AI systems, the effects could be far-reaching. AI models and training techniques could become some of the most valuable intellectual property in the technology sector, attracting investment but also raising the stakes in an already intense race to develop more powerful systems. At the same time, stronger patent protection could reshape competition, potentially allowing early movers to lock up key technological building blocks.

Ultimately, cases like DAACI reveal how uneasy the relationship between creativity and patent law has become. AI may be capable of composing music at the touch of a button, but the law still insists on asking the harder question: is the invention behind it is truly technical? And as AI grows more capable, that question is only going to get harder.
