The negative impact of climate change will continue way into the next century even if the world starts to reduce the concentration of greenhouse gases in the atmosphere by 2050, a study has revealed.
According to the research, even in a scenario of “negative emissions” by the middle of the century – where more greenhouse gases are removed from the atmosphere than are released – or if the world is at net-zero, areas of permafrost will keep thawing and giving out both carbon dioxide and methane.
One of the study authors, Dr Norman Steinert, a senior researcher at the Cicero Centre for International Climate Research in Oslo, said that permafrost responded on timescales that were centuries or millennia long, so he was “not surprised to see projection of permafrost as a long-term source of carbon emissions”.
“As long as temperatures are net positive relative to pre-industrial [times], permafrost will be exposed to a warmer climate and therefore emit carbon,” he told The National.
Most permafrost is in the Northern Hemisphere, with large areas around the Arctic in Alaska, Siberia, Canada and the Tibetan Plateau, although there is permafrost around the Antarctic too.
When it thaws it releases carbon dioxide and methane – which has a warming effect more than 25 times that of CO2 – because the organic matter trapped within it is broken down by microorganisms.
Can permafrost ever recover?
The research, published in Science Advances and also carried out by scientists in South Korea and the United States, involved computer modelling of changes in permafrost between the years 2000 and 2300.
Dr Steinert said that the amount of carbon released was determined by the temperature the permafrost had been exposed to, not just at any given point, but over time.
He also said that with negative emission scenarios, permafrost would cool more slowly than the air, which is another factor causing the release of carbon emissions to continue.
Climate change-induced alterations to a major ocean circulation pattern, the Atlantic Meridional Overturning Circulation (AMOC), which brings warm water from the tropics north, could have a cooling effect on permafrost, but not enough to cancel out other warming effects.
Effects such as cooling from a slowdown in the AMOC “cannot be an excuse to delay climate action”, according to Dr Steinert.
The scientific community is, he said, “still debating a potential tipping point for permafrost”, meaning a point at which global-scale thawing and the release of carbon emissions from it cannot be stopped.
Alternatively, permafrost thaw and associated carbon loss may happen gradually with every increment of global warming, without there being a warming level that can be considered “safe” until crossed.
A study last year indicated that a runaway effect was less likely than had been feared, and the new research indicates that there could be some recovery in permafrost area if temperatures fell sufficiently.
However, Dr Steinert said that permafrost carbon loss due to human-induced warming was irreversible on human timescales.
Time to act
Bob Ward, of the Grantham Research Institute on Climate Change and the Environment, part of the London School of Economics, said that he hoped “all countries would be paying attention” to findings like those in the new study.
“It's one example of the many ways we're carrying out an experiment without being aware of the many consequences,” he said. “It just shows that we're in a worse situation, even worse situation, than we realise ... If we carry on our current path, we’re not just going to trigger thawing permafrost, but many other climate thresholds [could be breached].”
This could result in, he said, the destabilisation of the polar ice sheets, changes to circulations in the North Atlantic, and “major disruption” to monsoons.
Some climate change-induced processes, such as sea-level rises, are set to continue for thousands of years, even without further greenhouse gas emissions, highlighted Asher Minns, executive director of the Tyndall Centre for Climate Change Research at the University of East Anglia in the UK.
“We should have turned off the CO2 taps maybe 20 or so years ago, so we’re well beyond the threshold when we should have acted,” he said. “That means action is needed even more urgently across all sectors of the planetary economy.”
Mr Minns also said that as well as efforts to mitigate climate change, prompt action was needed to adapt to its looming effects, as it is cheaper to act now than later.

Torno Subito by Massimo Bottura
When the W Dubai – The Palm hotel opens at the end of this year, one of the highlights will be Massimo Bottura’s new restaurant, Torno Subito, which promises “to take guests on a journey back to 1960s Italy”. It is the three Michelinstarred chef’s first venture in Dubai and should be every bit as ambitious as you would expect from the man whose restaurant in Italy, Osteria Francescana, was crowned number one in this year’s list of the World’s 50 Best Restaurants.
Akira Back Dubai
Another exciting opening at the W Dubai – The Palm hotel is South Korean chef Akira Back’s new restaurant, which will continue to showcase some of the finest Asian food in the world. Back, whose Seoul restaurant, Dosa, won a Michelin star last year, describes his menu as, “an innovative Japanese cuisine prepared with a Korean accent”.
Dinner by Heston Blumenthal
The highly experimental chef, whose dishes are as much about spectacle as taste, opens his first restaurant in Dubai next year. Housed at The Royal Atlantis Resort & Residences, Dinner by Heston Blumenthal will feature contemporary twists on recipes that date back to the 1300s, including goats’ milk cheesecake. Always remember with a Blumenthal dish: nothing is quite as it seems.

Essentials
The flights
Return flights from Dubai to Windhoek, with a combination of Emirates and Air Namibia, cost from US$790 (Dh2,902) via Johannesburg.
The trip
A 10-day self-drive in Namibia staying at a combination of the safari camps mentioned – Okonjima AfriCat, Little Kulala, Desert Rhino/Damaraland, Ongava – costs from $7,000 (Dh25,711) per person, including car hire (Toyota 4x4 or similar), but excluding international flights, with The Luxury Safari Company.
When to go
The cooler winter months, from June to September, are best, especially for game viewing.
Key findings
- Over a period of seven years, a team of scientists analysed dietary data from 50,000 North American adults.
- Eating one or two meals a day was associated with a relative decrease in BMI, compared with three meals. Snacks count as a meal. Likewise, participants who ate more than three meals a day experienced an increase in BMI: the more meals a day, the greater the increase.
- People who ate breakfast experienced a relative decrease in their BMI compared with “breakfast-skippers”.
- Those who turned the eating day on its head to make breakfast the biggest meal of the day, did even better.
- But scrapping dinner altogether gave the best results. The study found that the BMI of subjects who had a long overnight fast (of 18 hours or more) decreased when compared even with those who had a medium overnight fast, of between 12 and 17 hours.
Labour dispute
The insured employee may still file an ILOE claim even if a labour dispute is ongoing post termination, but the insurer may suspend or reject payment, until the courts resolve the dispute, especially if the reason for termination is contested. The outcome of the labour court proceedings can directly affect eligibility.

If you go
Flying
Despite the extreme distance, flying to Fairbanks is relatively simple, requiring just one transfer in Seattle, which can be reached directly from Dubai with Emirates for Dh6,800 return.
Touring
Gondwana Ecotours’ seven-day Polar Bear Adventure starts in Fairbanks in central Alaska before visiting Kaktovik and Utqiarvik on the North Slope. Polar bear viewing is highly likely in Kaktovik, with up to five two-hour boat tours included. Prices start from Dh11,500 per person, with all local flights, meals and accommodation included; gondwanaecotours.com
Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.

Essentials
The flights
Whether you trek after mountain gorillas in Rwanda, Uganda or the Congo, the most convenient international airport is in Rwanda’s capital city, Kigali. There are direct flights from Dubai a couple of days a week with RwandAir. Otherwise, an indirect route is available via Nairobi with Kenya Airways. Flydubai flies to Kinshasa in the Democratic Republic of Congo, via Entebbe in Uganda. Expect to pay from US$350 (Dh1,286) return, including taxes.
The tours
Superb ape-watching tours that take in all three gorilla countries mentioned above are run by Natural World Safaris. In September, the company will be operating a unique Ugandan ape safari guided by well-known primatologist Ben Garrod.
In the Democratic Republic of Congo, local operator Kivu Travel can organise pretty much any kind of safari throughout the Virunga National Park and elsewhere in eastern Congo.
