How Climate Change Impacts Global Economic Growth

🔥 Climate risks are no longer abstract—they’re disrupting businesses, communities, and economies right now. The World Economic Forum’s 2024 report, "The Cost of Inaction: A CEO Guide to Navigating Climate Risk", delivers a sobering message: ignoring climate risks isn’t just irresponsible—it’s economically devastating. 🌡️ Key insights from the report: 💥 Climate-related disasters have caused $3.6 trillion in damages since 2000, exposing critical vulnerabilities in supply chains and infrastructure. 📉 Physical risks could put 5-25% of EBITDA at risk for some sectors by 2050 under a 3°C warming trajectory. 💸 Transition risks, like carbon pricing and changing regulations, could impact 50% of EBITDA in energy-intensive industries by 2030. 🌱 Every $1 invested in climate adaptation yields $2-$19 in avoided costs, while green markets are projected to grow from $5 trillion in 2024 to $14 trillion by 2030. 💡 My reflections: 🔄 Resilience isn’t enough anymore. Too often, we focus on simply "weathering the storm" of climate risk. But true leadership is about rebuilding something better—rethinking markets, redesigning business models, and creating solutions that lead entire industries forward. 🌍 Supply chain fragility is the Achilles’ heel of the global economy. A single extreme weather event can cascade across operations, grinding everything to a halt. Climate-resilient supply chains can’t just be about survival—they must be radically adaptive, decentralized, and built to thrive under disruption. 📊 Climate risk is fundamentally redefining the concept of value. Businesses stuck chasing quarterly earnings are missing the bigger picture. In a world of rising costs and irreversible climate impacts, long-term value will belong to those who embed sustainability, resilience, and equity into their strategies. The time for cautious, incremental steps has passed. How are we using this moment to transform the way we work, innovate, and lead? #ClimateAction #Sustainability #Resilience #Leadership #Innovation

Climate change could reduce average income per person by 40% 🌎 A new study finds that a 4°C increase in global temperatures could reduce average global income by 40%, significantly more than previous estimates. Even with warming limited to 2°C, the expected decline in global GDP per capita is 16%—far higher than the 1.4% projected by earlier models. The findings suggest that current economic projections have underestimated the scale of financial losses associated with climate change. The research, published in Environmental Research Letters, critiques the traditional economic models known as integrated assessment models (IAMs). These models have played a key role in informing climate policy but have not fully accounted for the effects of extreme weather events or the interconnected nature of global supply chains. As a result, they have understated the broader economic impacts of climate risks. The new analysis improves on existing models by integrating updated climate forecasts and including the effects of supply chain disruptions caused by extreme weather. This approach provides a more comprehensive view of how climate change can impact economic systems, moving beyond the assumption that impacts are only local or easily offset by increased output elsewhere. The study challenges the idea that some regions could economically benefit from warming. While some colder regions might see marginal gains, the overall effect is negative due to the global nature of trade and economic interdependence. Disruptions in one part of the world can have cascading effects across sectors and geographies, reducing resilience and increasing vulnerability across the system. The authors conclude that current modelling practices risk underestimating both the costs of inaction and the benefits of rapid emissions reductions. Updating economic models to better reflect extreme risks and system-wide impacts is essential for informed policymaking. The findings reinforce the urgency of integrating climate risk into economic planning and decision-making. Source: The Guardian #sustainability #sustainable #business #esg #climatechange #risks

Very sobering report on the effects of climate on the global economy. We need dramatic and immediate emission reductions now. “But today's report takes a much more granular and empirical approach. It assesses the actual fallout from climate-related impacts on economic growth in over 1,600 subnational regions worldwide over the past 40 years, and then marries that analysis with the latest state of the art climate impact projections through to 2050.… The headline conclusion is that under a central scenario the global economy could face $38tr a year of climate damages a year by 2050, which would knock 19 per cent off projected per capita incomes. Such impacts are likely to already be locked in, even if the world now moves quickly to curb greenhouse gas emissions. Under worse case scenarios, climate damages could reach $59tr in 2050 and incomes could be 60 per cent lower than expected…. The overarching conclusion from the report is that, in the words of Wenz, "protecting our climate is much cheaper than not doing so, and that is without even considering non-economic impacts such as loss of life or biodiversity… The analysis also comes in a week when the way in which climate-related economic impacts could play out have been made painfully apparent. Dubai is starting to clean up after the worst floods in 75 years, after the city faced more rain in 24 hours than it usually received in a year and a half. A report from the Association of British Insurers confirmed the UK faced record levels of weather-related claims last year. And farmers in the UK and across much of Europe are warning they are set to endure one of the worst harvests in modern times due to extreme weather.” https://lnkd.in/eWu3b-Ru

Climate Change estimates a 12% GDP Hit: Why the Real Cost of Carbon Is 6x Higher Than previous research. New research by Adrien Bilal and Diego Känzig shows that the macroeconomic damage of climate change is six times larger than previously estimated. Global temperature rises—not local ones—are an economic threat, with a 1°C increase slashing global GDP by 12%. Their model sets the Social Cost of Carbon at $1,367/ton— above current policy benchmarks. Abstract: We estimate the macroeconomic damage function of climate change by combining a structural macroeconomic model with a new panel dataset for 174 countries over 1960–2019. Our approach overcomes the attenuation bias from local temperature shocks and separates the effects of persistent global warming from transitory local weather shocks. We find that a 1°C increase in global temperature leads to a 12% decline in world GDP. Damages are heterogeneous, with poorer and hotter countries suffering the most. These effects are driven by persistent productivity losses and are amplified by capital accumulation. Our estimated damage function implies a Social Cost of Carbon (SCC) of $1,385 per ton of carbon dioxide—more than six times the US government’s current estimate. Our results highlight the importance of accounting for macroeconomic persistence and heterogeneity when evaluating climate damages.” And link to paper in comments and below.

States and financial bodies using modelling that ignores shocks from extreme weather and climate tipping points, writes Damian Carrington. https://lnkd.in/et-3yWge Flawed economic models mean the accelerating impact of the #climatecrisis could lead to a global financial crash, experts warn. Recovery would be far harder than after the 2008 financial crash, they said, as “we can’t bail out the Earth like we did the banks”. As the world speeds towards 2C of global heating, the risks of extreme weather disasters and climate #tippingpoints are increasing fast. But current economic models used by governments and financial institutions entirely miss such shocks, the researchers said, instead forecasting that steady economic growth will be slowed only by gradually rising average temperatures. This is because the models assume the future will behave like the past, despite the burning of #fossilfuels pushing the climate system into uncharted territory. Tipping points, such as the collapse of critical Atlantic currents or the Greenland ice sheet, would have global consequences for society. Some are thought to be at, or very close to, their tipping points but the timing is difficult to predict. Combined #extremeweather disasters could wipe out national economies, the researchers, from the University of Exeter and financial thinktank Carbon Tracker, said. Their report concludes governments, regulators and financial managers must pay far more attention to these high impact but lower likelihood #risks, because avoiding irreversible outcomes by cutting carbon #emissions is far cheaper than trying to cope with them. “We’re not dealing with manageable economic adjustments,” said Dr Jesse F Abrams, at the University of Exeter. “The climate scientists we surveyed were unambiguous: current economic models can’t capture what matters most – the cascading failures and compounding shocks that define climate risk in a warmer world – and could undermine the very foundations of economic growth.” “For financial institutions and policymakers, it’s a fundamental misreading of the risks we face,” he said. “We are thinking about something like a 2008 [crash], but one we can’t recover from as well. Once we have ecosystem breakdown or #climatebreakdown, we can’t bail out the Earth like we did the banks.” Mark Campanale, CEO of Carbon Tracker, said: “The net result of flawed economic advice is widespread complacency amongst investors and policymakers. There’s a tendency in certain government departments to trivialise the impacts of climate on the economy so as to avoid making difficult choices today. This is a big problem – the consequences of delay are catastrophic.” Read more below. Read the report here: https://lnkd.in/erv73pNh

The cost of climate inaction is staggering—and avoidable. New research from Boston Consulting Group (BCG) and University of Cambridge shows that staying on a 3°C warming trajectory could slash global GDP by up to 34% by 2100. That would undermine global stability, economic resilience, and basic societal needs. The price of action? A fraction of what inaction would cost at just 1-2% of cumulative global GDP. Every dollar invested in climate mitigation and adaptation today delivers 5-14x in avoided damages and economic returns. It’s simple economics: The longer we wait, the higher the bill. https://lnkd.in/dtujkzfa?

How much climate change can the global economy “afford”? A recent study suggests we’ve been underestimating the economic risks of a warming planet. Traditional models often assess damage within national borders, looking at how each country is affected by events like droughts or storms on its own. But the world doesn’t work in silos. Economies are deeply interconnected, and disruptions in one region can ripple across the globe. This research takes a broader view, factoring in trade, supply chains, and other cross-border links. The results show that when these connections are included, projected global GDP losses from severe warming increase from 11% to 40%. And the economically “optimal” limit for warming drops from 2.7℃ to just 1.7℃. Climate change isn’t just a local or environmental issue—it’s a global economic challenge. Planning for the future means looking beyond borders and recognizing the full scale of interconnected risks.

Here are three weather events unfolding right now and their potential market impacts: 1. 🔥 Record-Breaking Heatwaves in the Northern Hemisphere What's Happening: North America and Europe are enduring record-high temperatures, exacerbating droughts and increasing wildfire risks. These heatwaves are a direct consequence of rising global temperatures, driven by human-induced climate change. Market Impact: Energy sectors are under pressure as electricity demand spikes, while agricultural outputs are threatened, potentially driving up food prices. Healthcare costs are also rising as populations grapple with heat-related illnesses. Expect volatility in stocks tied to energy, agriculture, and healthcare sectors as these heatwaves disrupt normal operations(Nature,IPCC). #2 🌳 Severe Drought in the Amazon What's Happening: The Amazon Basin, a vital carbon sink, is experiencing severe drought conditions. This situation is not only a climate crisis but a potential economic one, as the region plays a crucial role in global biodiversity and carbon sequestration. Market Impact: Deforestation and drought are set to disrupt supply chains, particularly in timber and agriculture, leading to scarcity and higher prices for raw materials. This disruption could ripple through global markets, impacting commodity prices and leading to increased uncertainty in sectors reliant on these resources(Yale Climate Connections,IPCC). 3. 🌊 Coastal Flooding in Southeast Asia What's Happening: Rising sea levels and land subsidence are causing major flooding in coastal regions like Jakarta, Indonesia. The combination of these factors could lead to massive infrastructure damage and the potential collapse of megacities. Market Impact: The threat to coastal infrastructure is alarming, with potential losses in real estate value and increased insurance claims. Markets may see a shift as investors reassess the risks associated with coastal regions, potentially leading to a reallocation of capital and increased borrowing costs for infrastructure projects aimed at mitigating these risks(Yale Climate Connections,IPCC). As these and other events continually unfold, they underscore the growing financial risks posed by climate change. #ClimateChange #FinancialMarkets #RiskManagement #Sustainability Anthropogenic

ECONOMIC IMPACTS FROM CLIMATE CHANGE Even if #co2emissions were to be drastically cut down starting today, the world economy would face an income reduction of 19 % by 2050 due to #climatechange. These damages are six times larger than the mitigation costs to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists at the Potsdam Institute for Climate Impact Research (PIK) assessed the future impacts of changing climatic conditions on economic growth and their persistence. KEY FINDINGS FROM THE STUDY: 🌡 Strong income reductions are projected for most regions. 🌡 Impacts will concentrate on agricultural yields, labor productivity, and infrastructure. 🌡 Global annual damages are estimated at 38 trillion dollars, with a likely range of 19-59 trillion Dollars in 2050. 🌡 Damages result from rising temperatures, rainfall and temperature variability, storms, and wildfires. 🌡 Climate change will cause massive economic damages within the next 25 years in almost all countries around the world, including developed ones such as Germany, France, and the United States. 🌡 Countries least responsible for climate change, are predicted to suffer income loss that is 60% greater than the higher-income countries and 40% greater than higher-emission countries. 🌡 In Mexico, it is estimated that the cumulative costs of climate change, during this century, would be comparable to losing between 85% and up to 5 times the GDP. 🌡 If emissions are not cut drastically, economic losses will become even bigger in the second half of the century, amounting to up to 60% of the global average by 2100. The study shows that protecting our climate is much cheaper than not doing so, and that is without even considering non-economic impacts such as loss of life or biodiversity. We can´t delay decisions any longer. Structural change towards a renewable energy system is needed for our security and will save us money. Staying on the path we are currently on, will lead to catastrophic consequences. Adaptation policies will need to be strengthened to further reduce potential economic impacts. #climaterisk #climateaction #netzero #esg https://lnkd.in/eNEjNm_p
