As a number of well being threats from local weather change break harmful new information, the 2024 Report of The Lancet Countdown on Well being and Local weather Change requires the trillions of {dollars} spent funding fossil fuels to be redirected and used to drive a fast and truthful transition to a internet zero greenhouse fuel (GHG) economic system, as an alternative of harming the well being of billions of individuals internationally.
“This 12 months’s stocktake of the approaching well being threats of local weather inaction reveals probably the most regarding findings but in our eight years of monitoring,” warned Dr Marina Romanello, Government Director of the Lancet Countdown at College Faculty London. “As soon as once more, final 12 months broke local weather change records-;with excessive warmth waves, lethal climate occasions, and devastating wildfires affecting individuals world wide. No particular person or economic system on the planet is immune from the well being threats of local weather change. The relentless enlargement of fossil fuels and record-breaking greenhouse fuel emissions compounds these harmful well being impacts, and is threatening to reverse the restricted progress made to date, and put a wholesome future additional out of attain.”
She added: “Regardless of this menace, we see monetary assets proceed to be invested within the very issues that undermine our well being. Repurposing the trillions of {dollars} being invested in, or subsidising, the fossil gas trade yearly would offer the chance to ship a good, equitable transition to scrub power and power effectivity, and a more healthy future, finally benefiting the worldwide economic system.”
The 8th Lancet Countdown annual indicator report, funded by Wellcome and developed in shut collaboration with the World Well being Group, represents the work of 122 main specialists from 57 tutorial establishments and UN companies globally, together with the World Well being Organisation (WHO) and the World Meteorological Organisation (WMO). Printed forward of the 29th UN Convention of the Events (COP), the report supplies probably the most up-to-date evaluation of the hyperlinks between well being and local weather change, together with new metrics which document excessive precipitation, stranded coal belongings, tree cowl loss, sand and dirt storms, rising nighttime temperatures and sleep loss, and local weather and well being training and coaching.
File-breaking human prices of local weather change
The 12 months 2023 was the most popular on document, with persistent droughts, lethal warmth waves, and devastating forest fires, storms and floods, and disastrous impacts on the well being, lives and livelihoods of individuals worldwide.
Warmth-related deaths proceed to quickly improve, and are anticipated to exceed cold-related deaths in a high-warming situation. Globally in 2023, heat-related deaths in these over age 65 elevated by a record-breaking 167% above deaths within the Nineties, considerably above the 65% improve that will have been anticipated had temperatures not modified (i.e., accounting just for altering demographics). This compounds current inequities, with the variety of health-threatening warmth days added by local weather change larger in nations with a low human growth index (a measure of training, earnings, and life expectancy).
Worldwide in 2023, individuals have been additionally uncovered to, on common, an all-time excessive of 1,512 hours of excessive temperatures posing a minimum of a average threat of warmth stress whereas enterprise gentle outside train equivalent to strolling or cycling-;a 27.7% improve (328 hours) on the 1990-1999 yearly common. Rising temperatures have additionally led to a document 512 billion potential hours of labour misplaced globally in 2023 (a 49% improve above the 1990-1999 common), with international potential earnings losses equal to US$835 billion-;equal to a considerable proportion of GDP in low- (7.6%) and middle-income nations (4.4%).
Over the past decade (2014-2023), 61% of the worldwide land space noticed a rise in excessive precipitation occasions in comparison with the 1961-1990 common, rising the chance of flooding, infectious illness, and water contamination. In parallel, extra frequent heatwaves and droughts have been accountable for 151 million extra individuals experiencing average to extreme meals insecurity in 124 nations in 2022, than yearly between 1981 and 2010. Consequently, the report estimates the full yearly worth of financial losses (linked to bodily belongings reasonably than ill-health) ensuing from excessive climate occasions at US$227 billion from 2019-2023, a price that exceeds the GDP of 60% of the world’s economies.
The climatic suitability for the unfold of lethal mosquito-borne infectious illnesses has additionally elevated. For instance, the transmission threat of dengue by Aedes albopictus mosquitoes rose by 46% and Aedes aegypti by 11% over the past decade (2014-2023) in comparison with 1951-1960. An all-time excessive of over 5 million dengue circumstances have been reported in over 80 nations/territories in 2023 [1].
“Individuals in all components of the world are more and more affected by the monetary and well being results of local weather change, and deprived communities in resource-limited nations are sometimes the worst affected, but supplied with the least monetary and technological protections,” mentioned Prof. Wenjia Cai, Lancet Countdown Working Group 4 Co-Chair at Tsinghua College.
Adaptation is failing to maintain tempo with the quickly rising well being threats of local weather change, and with limits to adaptation looming, and common well being protection nonetheless a pipe dream for greater than half the world’s inhabitants, monetary assist is urgently wanted to strengthen well being techniques to higher defend individuals.”

Governments and corporations proceed fuelling the fireplace, threatening to reverse restricted progress
New and up to date indicators reveal that governments and corporations proceed fuelling the fireplace with persistent investments in fossil fuels, all-time excessive GHG emissions, and staggering tree loss, decreasing the survival probabilities of individuals throughout the globe. In 2023, international energy-related carbon dioxide emissions reached an all-time excessive, 1.1% above 2022, and the proportion of fossil fuels within the international power system elevated for the primary time in a decade throughout 2021, reaching 80.3% of all power (up from 80.1% in 2020).
Whereas local weather motion is restricted by the dearth of funding, fossil gas funding nonetheless attracted 36.6% of worldwide power funding in 2023, with many governments additionally rising specific fossil gas subsidies in response to hovering power costs following Russia’s invasion of Ukraine. In 2022, 72 of the 86 nations (84%) analysed within the report subsidised fossil fuels for a document internet whole of US$1.4 trillion (considering the contribution of each carbon pricing and fossil gas subsidies), dwarfing any monetary commitments in assist of local weather motion made at COP28. These subsidies exceeded 10% of nationwide well being spending in 47 of the nations, and 100% in 23 nations.
In opposition to this regarding backdrop, the Loss and Harm Fund established at COP27 in 2022 to assist nations most susceptible to the impacts of local weather change, acquired preliminary pledges totalling the a lot smaller sum of US$700 million, which amounted to lower than 0.2% of the estimated requirement yearly [2]. Equally, the decade-long delay in delivering the comparatively modest sum of US$100 billion a 12 months promised to assist susceptible nations address local weather change has hampered progress and widened international inequities.
Bolstered by document earnings, the world’s 114 largest oil and fuel firms (overlaying 80% of all manufacturing projected by 2040) have elevated their projected fossil gas manufacturing ranges since final 12 months, which might result in their GHG emissions exceeding ranges suitable with 1.5°C of warming by 59% in 2030, and a staggering 189% in 2040, additional decreasing their compliance with the Paris Settlement. Worse nonetheless, 33 of those firms are anticipated to exceed their 1.5°C-compatible GHG emissions by over 300% in 2040.
Added to this, new information from this 12 months’s report estimates that just about 182 million hectares of forest have been destroyed between 2016 (when the Paris Settlement entered into power) and 2022, equal to five% of the worldwide tree cowl, diminishing the world’s pure capability to seize carbon dioxide. The best tree cowl losses have been in Russia (35.8 million hectares), the USA and Canada (virtually 15 million hectares in every nation). On the identical time, the rise in purple meat and dairy consumption elevated diet-related deaths by 220,000 between 2016 and 2021, and contributed to a 2.9% rise in agricultural GHG emissions.
Prof. Stella Hartinger, co-author and Lancet Countdown Latin America Director at Universidad Peruana Cayetano Heredia, mentioned: “Oil and fuel firms – supported by many governments and the worldwide monetary system – proceed to bolster the world’s habit to fossil fuels. In a world wherein survival is dependent upon phasing out fossil fuels, these short-sighted investments set us up for monetary turmoil as we pursue a habitable future. These perverse investments, coupled with the intense failure to make the mandatory structural modifications within the power sector to assist the net-zero transition, are jeopardising the economies on which individuals’s livelihoods rely, and leaving the well being and survival of thousands and thousands of individuals in danger.”
Redirecting funding to actions that benefit-;reasonably than harm-;individuals’s well being
Regardless of the record-breaking well being harms specified by the report, there are some causes for cautious optimism. Deaths from fossil fuel-derived air air pollution fell virtually 7% from 2.25 million in 2016 to 2.09 million in 2021, with 59% of this decline attributable to efforts to scale back air pollution from coal burning, demonstrating the life-saving potential of coal phase-out.
On the identical time, the share of electrical energy generated by clear trendy renewables reached 10.5% in 2021, virtually double that of 2016 (5.5%), whereas international funding in clear power grew 10% in 2023 to US$1.9 trillion, exceeding fossil gas funding by 73%. In the meantime, employment in renewables reached a record-high with 13.7 million staff in 2022 (35.6% improve since 2016), reaffirming that renewable power can assist job safety now and sooner or later.
“Progress in the direction of an equitable and wholesome future requires a worldwide transformation of monetary techniques, shifting assets away from the fossil-fuel based mostly economic system in the direction of a zero-emissions future,” mentioned co-author Prof. Anthony Costello, Co-Chair of the Lancet Countdown. “For profitable reform, individuals’s well being have to be put entrance and centre of local weather change coverage to make sure the funding mechanisms defend wellbeing, cut back well being inequities and maximise well being good points, particularly for the nations and communities that want it most.”
The report notes that the engagement of people, companies, scientists, and worldwide organisations with local weather change and well being is rising, elevating hopes {that a} wholesome, affluent future may nonetheless be inside attain.
“Amidst international turmoil, the highly effective and trusted management of the well being neighborhood may maintain the important thing to reversing these regarding developments and harnessing new alternatives to place the safety and promotion of well being and survival on the centre of political agendas,” mentioned Prof. Costello. “Nowhere will this be extra vital than at COP29 the place the monetary transition will take centre stage, providing a significant alternative to ship a resilient, more healthy future.”
Responding to the report publication, UN Secretary-Basic, António Guterres (who was not concerned in writing the report) mentioned: “File-high emissions are posing record-breaking threats to our well being. We should treatment the illness of local weather inaction – by slashing emissions, defending individuals from local weather extremes, and ending our fossil gas habit – to create a fairer, safer, and more healthy future for all.”
