What lies beneath Greenland could change what we know about
rising seas

by University of Ottawa
December 8, 2025

A new study led by researchers at the University of Ottawa
provides a series of highly detailed 3D models of the Earth's
temperature beneath Greenland and northeastern Canada, providing
insights into the region's geological history and the response of
the ice sheet to past and future climate change.

The study is published in the journal Proceedings of the National
Academy of Sciences.

Hidden heat beneath Greenland

The research was conducted at the University of Ottawa in
collaboration with scientists from the University of Twente in
the Netherlands and the Geological Survey of Denmark and
Greenland (GEUS). The study used multiple satellite and
land-based data sets and involved running hundreds of thousands
of simulations on high-performance computing resources, including
those at the Digital Research Alliance of Canada.

"Our new regional temperature models reveal significant lateral
variations in the Earth's thermal structure beneath Greenland,
which provide important information on the island's passage over
the Iceland hotspot," explains uOttawa's Ph.D. graduate Parviz
Ajourlou, the study's first author. "These variations help us
better interpret Greenland's tectonic history and the influence
of this history on the geophysical properties of the underlying
rocks."

Glenn Milne, Chair and Full Professor within the Department of
Earth and Environmental Sciences at uOttawa and the principal
investigator, emphasizes the implications, saying, "This research
advances our understanding of the Earth's internal structure
beneath Greenland. Temperature variations directly influence the
interaction between the ice sheet and the bedrock, which must be
quantified to interpret observations of land motion and gravity
changes. These observations tell us how the ice sheet is
responding to recent climate warming."

Modeling the future of sea levels

The innovative approach involved processing multiple geophysical
data sets such as seismic velocities, gravity anomalies, and heat
flow to develop a comprehensive 3D temperature model. The
findings not only clarify Greenland's geologic past and the
current state of the ice sheet but also improve the ability of
scientists to simulate future changes of the ice sheet and its
contribution to global sea level rise.

"This work is a good illustration of how our knowledge of the
solid Earth enhances our ability to understand the climate
system," says Ajourlou. "By improving how we model ice-earth
interactions, we can better forecast future sea level rise and
plan accordingly."

From Deutsche Welle:

Are Southeast Asian time zones all wrong?

David Hutt
November 29, 2025

An innocuous tweet from a Malaysian minister last week has
reignited a long-running debate about whether the Southeast Asian
country is in the right time zone.

In 1982, Peninsular Malaysia, the western part of the country,
moved its clocks forward by 30 minutes to align its time zone
with the states of Sabah and Sarawak on the island of Borneo.

The change, ordered by then-Prime Minister Mahathir Mohamad, was
presented as a nation-building and modernizing move that would
put the whole country on a single time.

But it also means that in Peninsular Malaysia the sun usually
rises at around 7 a.m., roughly an hour later than in East
Malaysia.

Some parents complain that they only have around 30 minutes of
daylight before schools start at 7:30 a.m., and little time for
children to eat breakfast or walk to school in daylight.

It also means that the sun sets relatively early, so many
Malaysians are still at work or commuting when it is already dark
and tend to eat long after sunset.

Reigniting the decades-old debate

Malaysian Minister of Investment, Trade and Industry Tengku
Zafrul Aziz was visiting Sabah's capital, Kota Kinabalu, when,
after one of his usual morning runs, he commented on social media
about the joy of an early jog.

"Here, sunrise comes early, so I could start running at 6:00am
before my first program at 8.30am this Sunday!" Aziz wrote on X.

What was supposed to be a jovial post about healthy living
reignited the embers of a decades-old debate.

Many social media users have called on the government to move the
clocks back an hour in Peninsular Malaysia, where the vast
majority of the country's population lives.

Malaysian newspapers have published several articles on the
question, and morning talk shows have invited experts to weigh
in.

"I was recently in [Philippines' capital] Manila for a business
trip, and it was nice to have a few hours of sunshine before
heading into the office," Mohd Rahman, who works at a major bank
in Kuala Lumpur, told DW.

Siti Abdullah, a mother of two in Georgetown, in northwest
Malaysia, said that she had no idea about the science, but "a lot
of people here think a change of time zone would be good for our
health. It would certainly help with the school run."

Some medical experts DW spoke to said there is little solid
scientific evidence to support those claims, although the topic
has clearly become something of a national talking point.

It even reached parliament last year, although then-Minister of
Investment, Trade and Industry Liew Chin Tong replied that any
time zone change would have a "significant impact on the economy"
and said that the government was not considering a change.

A history of shifting clocks

Both Singapore and Malaysia were forced to switch to GMT+9 during
World War II at the orders of their Japanese occupiers, who
wanted the region to follow Tokyo time.

After the war, Peninsular Malaysia adopted UTC+7:30, a halfway
point between its earlier time and the wartime clocks, before
moving again to GMT+8 on January 1, 1982.

This leaves Kuala Lumpur, the Malaysian capital, in an unusual
position. It sits at a similar longitude to Thailand's capital
Bangkok and Indonesia's capital Jakarta, yet operates an hour
ahead of both cities. At the same time, it shares a time zone
with Manila, the Philippine capital, which lies about 2,500
kilometers to the east.

Singapore, at the southern tip of Peninsular Malaysia, followed
Kuala Lumpur's lead in 1982 and also moved to GMT+8 to "avoid
inconvenience to businessmen and travelers," according to its
government at the time.

According to some critics, the lack of early-morning sun and an
early sunset disrupts Malaysians' circadian rhythms, the 24-hour
cycle of physical, mental and behavioral changes regulated by
light and darkness.

However, experts are skeptical.

Mahadir Ahmad, a senior lecturer and clinical psychologist at the
National University of Malaysia, told DW that he is not convinced
a one-hour difference is significant enough to cause widespread
health problems, noting that there is no strong evidence from
regional studies to support that claim.

"What is more important is to maintain the sleep-wake cycle
(circadian rhythm), and as long as our sleep routine does not
suppress melatonin production, we could go to sleep and wake up
based on the daytime and nighttime cycle," he said.

"The existing evidence shows that sleep deprivation and circadian
misalignment could cause cognitive performance and mood
disturbances," he added.

Nurul Aqilah Hasan Ashaari, a clinical dietitian, pointed out
that several other Southeast Asian countries that follow a
"right" time zone have worse health indicators than Malaysia, and
that social behaviors such as diet, exercise and working hours
are far more important than the precise time the sun rises or
sets.

For now, scientists say, Malaysia's health challenges appear to
be driven more by lifestyle than by its position on the world
time zone map.

One ASEAN time?

In parallel, there is a similarly loud chorus of calls for
Malaysia to stay on GMT+8 but for the rest of Southeast Asia to
follow suit, albeit for economic rather than health reasons.

In January, Abdul Wahid Omar, the chairman of Bursa Malaysia, the
country's stock exchange, argued that the entire Association of
Southeast Asian Nations (ASEAN) region should adopt a common time
zone, which, conveniently for Malaysia, he said ought to be
GMT+8.

This would "further integrate ASEAN as a compelling economic
bloc" and align the region with China, Hong Kong and Taiwan, he
told a business forum earlier this year.

Singapore, which is also on GMT+8, has publicly backed this idea.
It was first mooted by the city-state's then-premier, Goh Chok
Tong, in 1995, resurfaced in 2006, and again in 2015, when
Malaysia last held the ASEAN chairmanship.

Adopting a single time zone would require major changes.
Thailand, Cambodia, Laos and Vietnam would have to move from
GMT+7, although Bangkok and Hanoi have floated the idea in the
past.

Myanmar, currently on GMT+6:30, would have to move its clocks
forward by an hour and a half.

Indonesia would face the biggest challenge. The vast archipelago
spans three time zones — GMT+7, GMT+8 and GMT+9, although the
island of Java, where most of its major cities are located,
adheres to GMT+7.

There have been on-and-off discussions since 2012 about unifying
the country under a single GMT+8 time zone, but the proposal has
repeatedly been postponed and never implemented.

For now, Southeast Asia remains almost evenly split between GMT+7
and GMT+8, with Peninsular Malaysia and Singapore the outliers.

Whether a minister's enjoyment of a morning run is enough to
shift the region's clocks remains an open question.
