Climate change is destroying the world's oldest cave art

Ancient cave paintings in Indonesia, some dating back up to 45,000 years, have been irreparably damaged due to climate change.

Found on the Maros-Pangkep site on Sulawesi island, the limestone cave walls are adorned with hand stencils of red and mulberry tint, in addition to paintings of native mammals and human-animal hybrids.

Scientists believe these to be the earliest examples of cave art in the world. A painting of a Sulawesi warty pig, for example, has been deemed by scientists to be at least 45,500 years old.

These creations are fading fast, thanks to climate change. Even worse, the deterioration is irreversible, says Jillian Huntley, an archaeologist who has led a recent study into the impact of the climate crisis in the region.

Working with Australian and Indonesian researchers, Huntley, who is also a research fellow at the Place, Evolution and Rock Art Heritage Unit at Griffith University in Australia, published a paper in Nature on Thursday detailing these concerns.

As part of their work, researchers examined 11 caves in the Maros-Pangkep site. The paintings inside range from 20,000 to 45,000 years old. Changes in temperature and humidity have had their effect on the paintings, and even archaeologists from the 1950s have noticed that the works had started to peel.

However, the latest study from Huntley and her team reveals that man-made climate change, which brings about more severe periods of El Nino, a period of warming in the region, is accelerating the damage of the art.

These episodes of El Nino bring about drought and monsoon rains, consequently causing salts and minerals to crystallize on the cave walls, essentially stripping the surfaces where the works reside. As these crystal salts contract and expand due to the weather changes, the pressure can cause cracks to the paintings.

“In almost all sites containing early art, the hand stencils and figurative motifs are heavily affected by exfoliation of the limestone cave wall and ceiling surfaces that comprise the artists’ ‘canvas,’” the study states. The authors added that evidence points out that the “rate of exfoliation is increasing.”

In addition, the researchers state that the caves have been monitored on the same level as other prehistoric caves in Europe. The caves in the west do not have to endure the vast fluctuations in weather as those in tropical regions.

Currently, the Balai Pelestarian Cagar Budaya cultural heritage agency has launched a monitoring programme aid for documenting the state of the paintings, though researchers have urged for more support of the initiative.

The Lost Letters of William Woolf

Ten tax points to be aware of in 2026

1. Domestic VAT refund amendments: request your refund within five years

If a business does not apply for the refund on time, they lose their credit.

2. E-invoicing in the UAE

Businesses should continue preparing for the implementation of e-invoicing in the UAE, with 2026 a preparation and transition period ahead of phased mandatory adoption. 

3. More tax audits

Tax authorities are increasingly using data already available across multiple filings to identify audit risks. 

4. More beneficial VAT and excise tax penalty regime

Tax disputes are expected to become more frequent and more structured, with clearer administrative objection and appeal processes. The UAE has adopted a new penalty regime for VAT and excise disputes, which now mirrors the penalty regime for corporate tax.

5. Greater emphasis on statutory audit

There is a greater need for the accuracy of financial statements. The International Financial Reporting Standards standards need to be strictly adhered to and, as a result, the quality of the audits will need to increase.

6. Further transfer pricing enforcement

Transfer pricing enforcement, which refers to the practice of establishing prices for internal transactions between related entities, is expected to broaden in scope. The UAE will shortly open the possibility to negotiate advance pricing agreements, or essentially rulings for transfer pricing purposes. 

7. Limited time periods for audits

Recent amendments also introduce a default five-year limitation period for tax audits and assessments, subject to specific statutory exceptions. While the standard audit and assessment period is five years, this may be extended to up to 15 years in cases involving fraud or tax evasion. 

8. Pillar 2 implementation 

Many multinational groups will begin to feel the practical effect of the Domestic Minimum Top-Up Tax (DMTT), the UAE's implementation of the OECD’s global minimum tax under Pillar 2. While the rules apply for financial years starting on or after January 1, 2025, it is 2026 that marks the transition to an operational phase.

9. Reduced compliance obligations for imported goods and services

Businesses that apply the reverse-charge mechanism for VAT purposes in the UAE may benefit from reduced compliance obligations. 

10. Substance and CbC reporting focus

Tax authorities are expected to continue strengthening the enforcement of economic substance and Country-by-Country (CbC) reporting frameworks. In the UAE, these regimes are increasingly being used as risk-assessment tools, providing tax authorities with a comprehensive view of multinational groups’ global footprints and enabling them to assess whether profits are aligned with real economic activity.

Know before you go
  • Jebel Akhdar is a two-hour drive from Muscat airport or a six-hour drive from Dubai. It’s impossible to visit by car unless you have a 4x4. Phone ahead to the hotel to arrange a transfer.
  • If you’re driving, make sure your insurance covers Oman.
  • By air: Budget airlines Air Arabia, Flydubai and SalamAir offer direct routes to Muscat from the UAE.
  • Tourists from the Emirates (UAE nationals not included) must apply for an Omani visa online before arrival at evisa.rop.gov.om. The process typically takes several days.
  • Flash floods are probable due to the terrain and a lack of drainage. Always check the weather before venturing into any canyons or other remote areas and identify a plan of escape that includes high ground, shelter and parking where your car won’t be overtaken by sudden downpours.

 

Anxiety and work stress major factors

Anxiety, work stress and social isolation are all factors in the recogised rise in mental health problems.

A study UAE Ministry of Health researchers published in the summer also cited struggles with weight and illnesses as major contributors.

Its authors analysed a dozen separate UAE studies between 2007 and 2017. Prevalence was often higher in university students, women and in people on low incomes.

One showed 28 per cent of female students at a Dubai university reported symptoms linked to depression. Another in Al Ain found 22.2 per cent of students had depressive symptoms - five times the global average.

It said the country has made strides to address mental health problems but said: “Our review highlights the overall prevalence of depressive symptoms and depression, which may long have been overlooked."

Prof Samir Al Adawi, of the department of behavioural medicine at Sultan Qaboos University in Oman, who was not involved in the study but is a recognised expert in the Gulf, said how mental health is discussed varies significantly between cultures and nationalities.

“The problem we have in the Gulf is the cross-cultural differences and how people articulate emotional distress," said Prof Al Adawi. 

“Someone will say that I have physical complaints rather than emotional complaints. This is the major problem with any discussion around depression."
