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.

How Tesla’s price correction has hit fund managers
Investing in disruptive technology can be a bumpy ride, as investors in Tesla were reminded on Friday, when its stock dropped 7.5 per cent in early trading to $575.
It recovered slightly but still ended the week 15 per cent lower and is down a third from its all-time high of $883 on January 26. The electric car maker’s market cap fell from $834 billion to about $567bn in that time, a drop of an astonishing $267bn, and a blow for those who bought Tesla stock late.
The collapse also hit fund managers that have gone big on Tesla, notably the UK-based Scottish Mortgage Investment Trust and Cathie Wood’s ARK Innovation ETF.
Tesla is the top holding in both funds, making up a hefty 10 per cent of total assets under management. Both funds have fallen by a quarter in the past month.
Matt Weller, global head of market research at GAIN Capital, recently warned that Tesla founder Elon Musk had “flown a bit too close to the sun”, after getting carried away by investing $1.5bn of the company’s money in Bitcoin.
He also predicted Tesla’s sales could struggle as traditional auto manufacturers ramp up electric car production, destroying its first mover advantage.
AJ Bell’s Russ Mould warns that many investors buy tech stocks when earnings forecasts are rising, almost regardless of valuation. “When it works, it really works. But when it goes wrong, elevated valuations leave little or no downside protection.”
A Tesla correction was probably baked in after last year’s astonishing share price surge, and many investors will see this as an opportunity to load up at a reduced price.
Dramatic swings are to be expected when investing in disruptive technology, as Ms Wood at ARK makes clear.
Every week, she sends subscribers a commentary listing “stocks in our strategies that have appreciated or dropped more than 15 per cent in a day” during the week.
Her latest commentary, issued on Friday, showed seven stocks displaying extreme volatility, led by ExOne, a leader in binder jetting 3D printing technology. It jumped 24 per cent, boosted by news that fellow 3D printing specialist Stratasys had beaten fourth-quarter revenues and earnings expectations, seen as good news for the sector.
By contrast, computational drug and material discovery company Schrödinger fell 27 per cent after quarterly and full-year results showed its core software sales and drug development pipeline slowing.
Despite that setback, Ms Wood remains positive, arguing that its “medicinal chemistry platform offers a powerful and unique view into chemical space”.
In her weekly video view, she remains bullish, stating that: “We are on the right side of change, and disruptive innovation is going to deliver exponential growth trajectories for many of our companies, in fact, most of them.”
Ms Wood remains committed to Tesla as she expects global electric car sales to compound at an average annual rate of 82 per cent for the next five years.
She said these are so “enormous that some people find them unbelievable”, and argues that this scepticism, especially among institutional investors, “festers” and creates a great opportunity for ARK.
Only you can decide whether you are a believer or a festering sceptic. If it’s the former, then buckle up.

Top tips
Create and maintain a strong bond between yourself and your child, through sensitivity, responsiveness, touch, talk and play. “The bond you have with your kids is the blueprint for the relationships they will have later on in life,” says Dr Sarah Rasmi, a psychologist.
Set a good example. Practise what you preach, so if you want to raise kind children, they need to see you being kind and hear you explaining to them what kindness is. So, “narrate your behaviour”.
Praise the positive rather than focusing on the negative. Catch them when they’re being good and acknowledge it.
Show empathy towards your child’s needs as well as your own. Take care of yourself so that you can be calm, loving and respectful, rather than angry and frustrated.
Be open to communication, goal-setting and problem-solving, says Dr Thoraiya Kanafani. “It is important to recognise that there is a fine line between positive parenting and becoming parents who overanalyse their children and provide more emotional context than what is in the child’s emotional development to understand.”
