Study of glaciers in the Andes sheds light on future climate impact
ANDEAN glaciers advanced during an acute period of climate change at the end of the last Ice Age, new research has found.
An international team of glaciologists, led by Aberystwyth University, made the discovery as part of a new project into tropical glaciers in Peru. The finding challenges long-held assumptions about glacier behaviour during this period.
The findings, published in ‘Nature Scientific Reports’, shed new light on how glaciers respond to shifting climate patterns and may help improve predictions of future climate impacts.
The study focused on the Younger Dryas period, a time of sudden and dramatic climate change that occurred approximately 12,900 to 11,700 years ago. Contrary to previous theories, which suggest that glaciers in this area of Peru retreated during this time, the researchers found that those in the Santa Cruz Valley of Peru actually grew.
The glaciologists believe that this advance was driven by increased snowfall linked to seasonal shifts in the Intertropical Convergence Zone – a belt of low pressure that moves between the hemispheres and influences tropical weather patterns.
To reach their conclusions, the research team dated boulders transported and deposited by glaciers in the Santa Cruz Valley, Peru. Once deposited, these boulders serve as physical evidence of glacial movement over millennia and provide valuable insights into historical climate conditions.
Lead author Professor Neil Glasser from Aberystwyth University is a glacial geomorphologist who researches glacier change in southern South America. He said:
“Our study suggests that snowfall was a key factor driving glacier growth in the tropical Andes during the Younger Dryas. Unlike many other glaciers, the glaciers in this part of the Andes do not calve icebergs, where large sections of ice detach. They also lack heavy debris cover, making them especially well-suited for reconstructing past climate conditions. We were also able to date the timing of their advances more precisely than ever before.
“Our study shows that these glaciers are highly sensitive to climate shifts, particularly changes in precipitation patterns. Understanding the history of glacier advance and recession is really important because it helps us better anticipate how these glaciers will respond to future warming. This is especially important in Peru, where the glaciers are a source of fresh water for drinking, sanitation and irrigation of crops.”
The study was a collaborative effort involving researchers from the UK, Italy, Canada, and Peru.

Tenby students compete in UK robotics challenge
STUDENTS from Ysgol Greenhill in Tenby have taken part in the FIRST Tech Challenge UK & Ireland competition, showcasing their engineering and computing skills at a national robotics event.
The Tenby Techno Team travelled to the University of Wales Trinity Saint David’s School of Applied Computingwhere teams from across the UK and Ireland gathered to compete in the international robotics programme.
The competition challenges students to design, build and programme robots capable of completing tasks on a specialist arena, testing both technical ability and teamwork.
The Tenby team said they were proud to be competing and were supported during the event by former computing students Issac, Ieuan and Finley, who returned to help the team as volunteers.

Organisers of the programme say the FIRST Tech Challenge aims to inspire young people to pursue careers in science, technology, engineering and mathematics while building practical problem-solving skills.
The team also thanked Valero Pembroke Refinery and Tenby Round Table for sponsoring the project, along with Marc Ingram, who provided advice and guidance during the build and preparation stages.
More updates from the competition are expected as the event progresses.

Influencers amplify misinformation and online toxicity, study finds
SOCIAL media influencers can significantly increase the spread and toxicity of misinformation online, according to new research led by academics at Cardiff Business School.
The study, published in the journal Psychology & Marketing, analysed brand-related misinformation and associated user comments across forty-seven brands in nine industries over a three-year period. Researchers say it is the first study to measure how online toxicity differs when misinformation comes from influencers rather than ordinary users.
Brands increasingly rely on social media influencers to reach audiences, with spending on influencer marketing hitting a record $33bn in 2025. While influencers can drive engagement and sales, the communities built around them can also amplify inaccurate claims and direct hostility towards brands.
The research found that regular social media users who spread misinformation are often challenged or criticised by other users. As a result, discussions tend to become more civil over time as inaccuracies are corrected.
Influencers, however, face the opposite incentive. Their visibility, engagement and profits often increase when posts generate controversy or strong emotional reactions.
The analysis found that online toxicity was particularly high when influencers discussed socio-political issues, where public emotions and stakes are greater.
Lead author Dr Giandomenico Di Domenico said: “Social media influencers often have huge followings that are extremely valuable for brands seeking to increase sales.
“But our research shows the negative consequences when influencers endorse or amplify misinformation. Under the same conditions that increase their visibility and influence, influencers also generate significantly more toxic engagement than regular users.”
He explained that the close relationships influencers cultivate with their followers play a key role.
“Unlike regular users, influencers form parasocial bonds with their communities. These relationships make followers far more likely to support or defend claims without critically questioning them.
“This means misinformation introduced within these networks does not simply attract attention — it can transform scattered reactions into collective, belief-driven antagonism.”
The researchers identified two key mechanisms that strengthen misinformation when it comes from influencers.
The first is “legitimation”, where the influencer’s endorsement lends credibility to a claim. The second is “community enmeshment”, where followers rally around the influencer and reinforce the narrative.
When combined, these factors can create what researchers describe as “toxic echo chambers”, producing a self-reinforcing cycle in which toxicity increases engagement — and engagement encourages further inflammatory content.
The study highlights how these dynamics played out in early 2025 when several TikTok influencers posted viral videos claiming luxury brands including Hermès, Louis Vuitton and Chanel secretly manufactured products in Chinese factories while marketing them as “Made in France” or “Made in Italy”.
The videos presented the claims as exposés of industry deception but offered no verifiable evidence. Despite this, they generated millions of views and fuelled widespread online debate about authenticity, ethics and transparency in the luxury industry.
Dr Di Domenico said the example illustrates a growing tension within influencer culture.
“Despite the positive impact influencers can have on marketing outcomes, their prominence also introduces new risks,” he said.
“When misleading or controversial claims are amplified by influencers, the resulting backlash can create highly toxic environments that damage brands and distort public understanding.”
The research paper, titled Don’t You Know That You’re Toxic? How Influencer-Driven Misinformation Fuels Online Toxicity, is published in Psychology & Marketing.
