The authors of this article on Climate change and elaborate on how to avert it through experts’ notable advice of a ditch of 90% of the world’s coal and 60% of oil and gas to limit warming to 1.5°C. Would it be feasible if some of the MENA countries economic life sustenance depends on fossil fuels related revenues? Here is what these authors are saying.
Climate change: ditch 90% of world’s coal and 60% of oil and gas to limit warming to 1.5°C – experts
Global mean surface temperatures reached 1.2°C above the pre-industrial average in 2020, and the Intergovernmental Panel on Climate Change warned in its recent report that Earth could hit 1.5°C in as little as a decade. The 0.3°C separating these two temperatures make a world of difference. Scientists believe that stabilising our warming world’s temperature at 1.5°C could help avoid the most serious effects of climate change.
Fossil fuels such as coal, oil and natural gas are the source of just over 80% of the world’s energy. Burning them accounts for 89% of human-derived CO₂ emissions. To avert catastrophic warming, the global community must rapidly reduce how much of these fuels it extracts and burns. Our new paper, published in Nature, revealed just how tight the world’s remaining carbon budget is likely to be.
In order to hold global warming at 1.5°C, we found that nearly 60% of global oil and fossil gas reserves will need to remain in the ground in 2050. Almost all of the world’s coal – 90% – will need to be spared from factory and power plant furnaces. Our analysis also showed that global oil and gas production must peak immediately and fall by 3% each year until mid-century.
Even meeting these stringent limits may not be enough on its own to stabilise global warming at 1.5°C, however.
That’s because we based our estimates on a carbon budget compatible with just a 50% probability of limiting warming to 1.5°C. Our model simply could not be pushed to a greater chance of achieving the 1.5C target because it was already at its limit, given our projections of fossil fuel demand in the near future.
Our analysis also relies on the large-scale deployment of technologies capable of removing CO₂ from the atmosphere sometime in the future. By 2050, our scenario expects around four gigatonnes a year will be being captured by so-called negative emission technologies. There remains a lot of doubt about whether it is even possible to sufficiently scale these technologies up in time.
So, to aim for a better chance of achieving the Paris Agreement’s goal and to lower the risk of relying on as yet unproven technologies, we argue that our estimates of how much of the world’s fossil fuels cannot safely be extracted should be treated as cautious underestimates. The world may need to be even more ambitious.
Fossil fuel rationing
We estimated how much fossil fuel production in each region must fall and how fast based on a global energy system model. We allocated the remaining shares of fossil fuel production allowed within the budget based on the costs and carbon intensity of producing different oil and gas assets, and how cheap low and zero-carbon technologies are in different parts of the world.
Our analysis showed that total fossil fuel production is limited by a global carbon budget. Production growing in one region of the world will require a decrease in another to keep the global trajectory pointing downwards. A mechanism such as the Global Fossil Fuel Registry – a public database of all known reserves – could provide the necessary transparency for an international effort, with the cooperation of governments and fossil fuel producers.
The US and Russia sit on half of the world’s coal but must leave 97% of it in the ground. Australia, which recently pledged to keep producing and exporting coal beyond 2030, would need to keep 95% of its reserves underground. Oil-producing states in the Middle East must not extract around two-thirds of their reserves, while most of Canada’s tar sand oil must not be burned, along with all of the fossil fuel buried beneath the Arctic.
Our analysis suggests that many countries will need to move out of fossil fuel production relatively quickly, which raises concerns about how the transition can be managed fairly. Countries such as Iraq and Angola have a high dependency on fossil fuels for government revenues. They will need support to diversify their economies in a managed way – including financial and technological assistance to develop new low-carbon industries – and to decarbonise domestically to reduce their own reliance on fossil fuels.
The necessary energy transformation highlighted in this research will require a range of policy levers, including measures that drive down fossil fuel consumption, such as banning petrol cars or promoting renewable electricity generation, and those targeting production itself, including restrictions on new fossil fuel extraction licenses.
Alliances between countries are also likely to be important to build political support for reducing fossil fuel production. The Beyond Oil and Gas Alliance, formed by Denmark and Costa Rica, has pressured other countries to halt investment in new oil and gas projects.
Phasing out global fossil fuel production at the rate suggested in our study is possible, but it will rely on some of the measures we’ve described expanding and gaining the support of large producing countries and companies – those which have benefited most from the fossil fuel era.
Construction Week of September 8, 2021, shows us how the “new normal” brings digital transformation in the built environment in an article by Mina Vucic. It is no more than a step however small but lucrative and most importantly in the right direction. Here is how it is.
How the “new normal” brings digital transformation in the built environmentan article
Asite speaks on changing the ways in which cities operate by “using technology to enhance collaboration through data sharing”.
Middle East cities have been leading the way in smart city development, acting as pioneers in implementing innovative, sustainable, and integrated solutions to become greener, more efficient, and better places to live.
Disruption and innovation have changed the way specialists think and operate across sectors, particularly in the past year as the COVID-19 pandemic has pushed most industries out of their comfort zone and into digitally-enabled environments.
Doughty said that in order to effectively drive the digital transformation of cities, the industry should focus on enhancing the precision of structural data.
He added: “The number one method we should be prioritising in order to achieve our goals at corporate, governmental, and global levels is using technology to enhance collaboration through data sharing.”
Some of the examples Doughty shared in the real world include COVID-19 track and trace systems, satellite-based navigation, social media in smart cities, artificial intelligence (AI), machine learning, and most importantly off-site construction and BIM.
Placing his focus on the modern construction methods Doughty emphasised: “In order to retrofit and repurpose the assets we must focus on creating energy-efficient buildings, decarbonise the built environment, and improve digital infrastructure’s operational efficiency.”
According to Asite’s CEO, one of the key methods to achieve those goals is to drive the circular economy, designing out pollution, keeping materials in use, and regenerating natural systems.
Doughty added: “We must emphasise the use of digital technologies on smart buildings, embedding sensors, gathering data, and analysing the information received to make informed decisions.”
Although the pandemic has challenged the traditional methods of construction, many organisations are now adopting BIM in the industry, providing a platform of know-how that can be built on for future technologies and more sustainable cities.
The article on the Economic Cost of Climate Change being six times higher than previously thought, published by UCL though alarming cannot be closer to the drastic reality of today. Here it is.
Economic cost of climate change could be six times higher than previously thought
6 September 2021
Economic models of climate change may have substantially underestimated the costs of continued warming, according to a new study involving UCL researchers.
Published today in the journal Environmental Research Letters, the international team of scientists found that the economic damage could be six times higher by the end of this century than previously estimated.
Projections like this help governments around the world calculate the relative costs and benefits of cutting greenhouse gas emissions. However, prior analysis has shown that the models used may ignore important risks and therefore underestimate the costs.
Currently, most models focus on short-term damage, assuming that climate change has no lasting effect on economic growth, despite growing evidence to the contrary. Extreme events like droughts, fires, heatwaves and storms are likely to cause long-term economic harm because of their impact on health, savings and labour productivity.
The study authors first updated one of the three climate-economy models used to set the price of carbon for national policy decisions, then used it to explore the impact of year-to-year climate variations and the rates of economic recovery after climate events.
The study shows that by 2100, global GDP could be 37% lower than it would be without the impacts of warming, when taking the effects of climate change on economic growth into account. Without accounting for lasting damages – excluded from most estimates – GDP would be around 6% lower, meaning the impacts on growth may increase the economic costs of climate change by a factor of six.
Yet, there is still considerable uncertainty about how much climate damages continue to affect long-term growth and how far societies can adapt to reduce these damages; depending on how much growth is affected, the economic costs of warming this century could be up to 51% of global GDP.
Study co-author Dr Chris Brierley (UCL Geography) said: “We don’t yet know exactly how much effect climate change will have on long-term economic growth – but it’s unlikely to be zero, as most economic models have assumed.
“Climate change makes detrimental events like the recent heatwave in North America and the floods in Europe much more likely. If we stop assuming that economies recover from such events within months, the costs of warming look much higher than usually stated. We still need a better understanding of how climate alters economic growth, but even in the presence of small long-term effects, cutting emissions becomes much more urgent.”
The researchers also updated the model to take advances in climate science over the past decade into account, as well as the effect of climate change on the variability of annual average temperatures – both of which increased the projected cost of climate change.
The authors calculated the effect of these changes on the ‘social cost of carbon’ (SCCO2), a crucial indicator of the level of urgency for taking climate action that calculates the economic cost of greenhouse gas emissions to society. Expressed in US dollars per tonne of carbon dioxide, estimates currently vary greatly between $10 to $1,000. However, when taking more robust climate science and updated models into account, this new study suggests that the economic damage could in fact be over $3,000 per tonne of CO2.
“Burning CO2 has a cost to society, even if it is not directly to our wallets. Each person’s emissions could quite well result in a cost to humanity of over $1,300 per year, rising to over $15,000 once the impacts of climate change on economic growth are included,” Dr Brierley said.
While the findings show large uncertainties, the central values were found to be much higher than policymakers currently assume; the US government, for example, currently uses a social cost of carbon of around $51 per tonne to judge the costs and benefits of projects linked with greenhouse gas emissions, whilst the EU Emissions Trading Scheme, which covers power, manufacturing and aviation, recently exceeded €61 for the first time.
Study co-author Paul Waidelich (ETH Zürich) said: “The findings confirm that it is cheaper to reduce greenhouse gas emissions than it is to deal with climate change impacts, and the economic damages from continued warming would greatly outweigh most costs that could be involved in preventing emissions now. The risk of costs being even higher than previously assumed reaffirms the urgency for fast and strong mitigation. It shows that choosing to not reduce greenhouse gas emissions is an extremely risky economic strategy.”
Former UCL MSc student and study lead author, Jarmo Kikstra (International Institute for Applied Systems Analysis and Imperial College London), said: “It is very difficult to calculate the overall costs of climate change, but increased scientific evidence has improved economic estimates. Climate science on this has improved a lot over the past decade, and the improvements we made with the science do not change the order of magnitude of cost-benefit estimates.
“However, we are much more uncertain when it comes to how the economy will respond to future climate impacts. We reveal that if we look more closely at the lasting impact the climate can have on economies, we find that the costs might increase many times, depending on how much climate action we take.”
Arabian Business‘ post on the GCC of all countries of the MENA region are taking action for a sustainable future because of how humanity having reached a ‘code red’ climate emergency. Here it is.
How humanity has reached a ‘code red’ climate emergency
The good news is that there is still a sliver of hope to help communities respond to this threat through well-informed, solid and sustained actions.
The recently published report by the Intergovernmental Panel on Climate Change (IPCC) describes unprecedented environmental changes as “irreversible for centuries to millennia”.
However, the good news is that there is still a sliver of hope to help communities respond to this threat through well-informed, solid and sustained actions.
Like the rest of the world, countries of the Gulf Cooperation Council (GCC) have started experiencing climate change first-hand with sparse rainfall, arid terrain, and high temperatures. Thus, its governments moved to adapt their climate change policies.
For example, Saudi Arabia launched the Saudi Green Initiative which aims to increase the kingdom’s reliance on clean energy, and combat climate change. Bloomberg Green reported earlier this year that Saudi Arabia is building a $5 billion solar and wind-powered plant to be among the world’s biggest green hydrogen makers when it opens in the planned megacity of Neom in 2025.
Meanwhile, the UAE has been undertaking many steps to control the effects of climate since the late 2000s with the establishment of Masdar in Abu Dhabi, which is currently hosting the International Renewable Energy Agency headquarters. Dubai also inaugurated the third phase of its largest solar park in the world last year, which targets a capacity of 5GW by 2030 to supply homes with clean energy and offset CO2 emissions.
Global funders of science – including philanthropy, the private sector and government agencies – have a vital role in delivering climate pledges. As we have seen with the fight against Covid-19, by focusing investments on supporting much-needed research and technology development, we can improve climate mitigation and adaptation efforts, and influence policy and identify behavioural interventions that support them. This prompts us to examine the role of privately-led science funding in the GCC in supporting climate change combat.
Research indicates that climate change directly impacts nutrition and public health. In the GCC, for example, MIT professor Elfatih Eltahir published a paper in Nature Climate Change, alongside Jeremy Pal of Loyola Marymount University, demonstrating that waves of heat and humidity in the region are likely to lead to temperature levels that are intolerable to humans. This research sounds a warning for the impact of increased urbanisation rates on livability in the GCC in the face of climate change.
The GCC can respond positively to climate change’s direct and indirect effects on communities, whether air pollution, nutrition, disease or even habitability.
With exceptions like Professor Eltahir’s study, there is little research and empirical evidence on the effects of adverse climate events on human health in the GCC region. Such research is urgently needed: Only by examining the most up-to-date and robust scientific evidence and analysis, can we understand how to tackle these challenges most effectively.
To this end, Community Jameel has partnered with AEON Collective, a leading Saudi-based sustainable development research and advocacy group, to bring together a consortium of world-leading international and local researchers in the areas of climate, food and water, and public health to inform policy recommendations in climate and health in the GCC.
This includes scientists from two research centres Community Jameel has founded at the Massachusetts Institute of Technology (MIT): the Jameel Water and Food Systems Lab (J-WAFS), which catalyses research and innovation at MIT to find solutions to urgent global water and food systems challenges; and the Jameel Poverty Action Lab (J-PAL), whose co-founders – Esther Duflo and Abhijit Banerjee – received the 2019 Nobel Prize in Economics for their experimental approach to tackling global poverty, and where the J-PAL King Climate Action Initiative is generating evidence on the effectiveness and cost-effectiveness of technological and policy innovations at the intersection of climate and poverty.
In order to bridge the gap between academia, policymakers and the private sector in the GCC, the consortium will draw on the expertise of researchers at J-WAFS and J-PAL, as well as local and other international institutions, to identify solutions, provide technical guidance, and improve our understanding of the complexity behind the policy changes required to implement science-based solutions in the region.
By strengthening the region’s climate resilience, the GCC can respond positively to climate change’s direct and indirect effects on communities, whether air pollution, nutrition, disease or even habitability. There is also an opportunity to capitalise on the strategic opportunities presented by the shift to a lower-carbon and resource-constrained economy.
We hope that this collaborative effort will galvanise further funding of research in – and for – the GCC and the specific challenges posed by climate change to the health of all of us living in this region.
Before a critical Opec conference, Iraq’s finance minister, one of the founding members of the global oil cartel Opec, issued an unusual plea to fellow oil producers to shift away from fossil fuel reliance and toward renewable energy.
Ali Allawi, Iraq’s deputy prime minister, urged oil producers to seek “an economic rejuvenation based on ecologically sound policies and technology,” such as solar electricity and even nuclear reactors, to lessen their reliance on fossil fuel exports.ADVERTISING
“To stand a chance of minimizing the worst consequences of climate change, the world has to radically transform the way it produces and uses energy, burning less coal, oil, and natural gas,” he wrote alongside Fatih Birol, executive director of the International Energy Agency. Livelihoods would be lost, and poverty rates will rise if oil earnings begin to fall before producer countries have properly diversified their economies.”
Ministers from the 13 Opec member states will meet virtually on Wednesday to discuss possible output cuts as oil prices fluctuate. Opec had agreed to raise output as nations recovered from the Covid-19 epidemic, but sluggish markets have led some to propose that the rise be halted.
Last month, US President Joe Biden made a contentious appeal for Opec to raise oil output, even more, keep oil prices from increasing and help the US economy recover. But, unfortunately, his appeal was turned down.
Fuel Step Up
In an unprecedented step for the fossil fuel companies, the Opec summit may also address the climate problem ahead of the crucial UN climate negotiations, known as Cop26, set for Glasgow in November.
According to Allawi and Birol, current oil price instability, fueled by the pandemic, is merely the beginning of troubles for producers. The climate issue will not only need a shift away from oil, but it will also have a particularly negative impact on the Middle East and North Africa, where increasing temperatures are already causing severe problems.
According to the International Energy Agency’s (IEA) recent global roadmap to net-zero by 2050, global oil demand is expected to fall from more than 90 million barrels per day to fewer than 25 million barrels per day by 2050, resulting in a potential 85 percent drop in revenues for oil-producing economies.
According to Allawi and Birol, economic hardship and rising unemployment risk causing greater discontent and instability in a region with one of the world’s youngest and fastest-growing populations.
Investing in renewables, particularly solar electricity, is an alternative to dependent on increasingly volatile oil prices. They added, “The energy industry might play a role here by utilizing the region’s tremendous potential for generating and supplying clean energy.”
Iraq is a founding member of the cartel, including Saudi Arabia, Kuwait, the United Arab Emirates, Venezuela, Nigeria, and several other African oil-producing countries. In addition, Russia and a few minor producers are included in the Opec+ alliance.
Most have been antagonistic to demands for action on climate change, while some have dismissed climate science, and Saudi Arabia, in particular, has often obstructed UN climate discussions.
The International Energy Agency (IEA) cautioned in May that if the world remains below 1.5 degrees Celsius over pre-industrial levels, as laid forth in the Paris Agreement – to which all Opec members are signatories – all new oil drilling must end this year.
When asked about the findings, Saudi Arabia’s energy minister, Prince Abdulaziz bin Salman, said at an Opec meeting in June, “I would have to voice my perspective that I feel it is a sequel to [the] La La Land movie…” But, “What makes you think I should take it seriously?”
Saudi officials have toyed with climate action in the past, claiming, for example, that the nation might eventually power itself with solar energy. However, no one has urged that oil shipments be halted.
Some oil producers, on the other hand, have chosen a more dovish attitude. For example, Oman, no longer an Opec member, looks at hydrogen as a future low-carbon fuel. The UAE also focuses on hydrogen and renewable energy and has just opened a new nuclear power plant. Other nations in the area with significant renewable energy programs include Egypt, Morocco, and Jordan.
“More than at any other time in history, significant adjustments to the economic model in resource-rich nations are unavoidable,” Birol, one of the world’s leading energy economists, told the Guardian. Countries in the region have made energy transition initiatives. There are encouraging attempts [among oil producers], but attaining net-zero emissions would need far bolder steps and much larger international coordination, as it has for many other nations across the world.”
