As a number of well being threats from local weather change break harmful new data, 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 gasoline (GHG) economic system, as a substitute of harming the well being of billions of individuals internationally.
“This 12 months’s stocktake of the upcoming well being threats of local weather inaction reveals essentially the most regarding findings but in our eight years of monitoring,” warned Dr Marina Romanello, Government Director of the Lancet Countdown at College School 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 folks all over the world. No particular person or economic system on the planet is immune from the well being threats of local weather change. The relentless growth of fossil fuels and record-breaking greenhouse gasoline emissions compounds these harmful well being impacts, and is threatening to reverse the restricted progress made thus far, and put a wholesome future additional out of attain.”
She added: “Regardless of this menace, we see monetary sources 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 gasoline business 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 consultants from 57 tutorial establishments and UN businesses globally, together with the World Well being Organisation (WHO) and the World Meteorological Organisation (WMO). Revealed forward of the 29th UN Convention of the Events (COP), the report gives essentially the most up-to-date evaluation of the hyperlinks between well being and local weather change, together with new metrics which file 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 file, 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 enhance, 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% enhance that may have been anticipated had temperatures not modified (i.e., accounting just for altering demographics). This compounds present inequities, with the variety of health-threatening warmth days added by local weather change increased in international locations with a low human improvement index (a measure of training, earnings, and life expectancy).
Worldwide in 2023, folks had been additionally uncovered to, on common, an all-time excessive of 1,512 hours of excessive temperatures posing no less than a average danger of warmth stress whereas endeavor gentle outside train comparable to strolling or cycling-;a 27.7% enhance (328 hours) on the 1990-1999 yearly common. Rising temperatures have additionally led to a file 512 billion potential hours of labour misplaced globally in 2023 (a 49% enhance above the 1990-1999 common), with world potential earnings losses equal to US$835 billion-;equal to a considerable proportion of GDP in low- (7.6%) and middle-income international locations (4.4%).
Over the last decade (2014-2023), 61% of the worldwide land space noticed a rise in excessive precipitation occasions in comparison with the 1961-1990 common, growing the danger of flooding, infectious illness, and water contamination. In parallel, extra frequent heatwaves and droughts had been answerable for 151 million extra folks experiencing average to extreme meals insecurity in 124 international locations in 2022, than yearly between 1981 and 2010. Because of this, the report estimates the whole 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 worth 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 danger of dengue by Aedes albopictus mosquitoes rose by 46% and Aedes aegypti by 11% during the last decade (2014-2023) in comparison with 1951-1960. An all-time excessive of over 5 million dengue instances had been reported in over 80 international locations/territories in 2023 [1].
“Folks in all elements 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 help is urgently wanted to strengthen well being techniques to higher defend folks.”

Governments and firms proceed fuelling the fireplace, threatening to reverse restricted progress
New and up to date indicators reveal that governments and firms proceed fuelling the fireplace with persistent investments in fossil fuels, all-time excessive GHG emissions, and staggering tree loss, decreasing the survival probabilities of folks throughout the globe. In 2023, world energy-related carbon dioxide emissions reached an all-time excessive, 1.1% above 2022, and the proportion of fossil fuels within the world 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 proscribed by the dearth of funding, fossil gasoline funding nonetheless attracted 36.6% of worldwide power funding in 2023, with many governments additionally growing specific fossil gasoline subsidies in response to hovering power costs following Russia’s invasion of Ukraine. In 2022, 72 of the 86 international locations (84%) analysed within the report subsidised fossil fuels for a file internet whole of US$1.4 trillion (taking into consideration the contribution of each carbon pricing and fossil gasoline subsidies), dwarfing any monetary commitments in help of local weather motion made at COP28. These subsidies exceeded 10% of nationwide well being spending in 47 of the international locations, and 100% in 23 international locations.
In opposition to this regarding backdrop, the Loss and Harm Fund established at COP27 in 2022 to help international locations most susceptible to the impacts of local weather change, obtained 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 help susceptible international locations deal with local weather change has hampered progress and widened world inequities.
Bolstered by file earnings, the world’s 114 largest oil and gasoline corporations (masking 80% of all manufacturing projected by 2040) have elevated their projected fossil gasoline manufacturing ranges since final 12 months, which might result in their GHG emissions exceeding ranges appropriate 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 corporations 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 nearly 182 million hectares of forest had been destroyed between 2016 (when the Paris Settlement entered into drive) 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 had 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 pink 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 gasoline corporations – supported by many governments and the worldwide monetary system – proceed to bolster the world’s habit to fossil fuels. In a world during which survival is determined by 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 help the net-zero transition, are jeopardising the economies on which individuals’s livelihoods rely, and leaving the well being and survival of hundreds of thousands of individuals in danger.”
Redirecting funding to actions that benefit-;reasonably than harm-;folks’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 as a result of 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 world funding in clear power grew 10% in 2023 to US$1.9 trillion, exceeding fossil gasoline funding by 73%. In the meantime, employment in renewables reached a record-high with 13.7 million staff in 2022 (35.6% enhance since 2016), reaffirming that renewable power can help job safety now and sooner or later.
“Progress in the direction of an equitable and wholesome future requires a world transformation of monetary techniques, shifting sources away from the fossil-fuel primarily based 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, folks’s well being have to be put entrance and centre of local weather change coverage to make sure the funding mechanisms defend wellbeing, scale back well being inequities and maximise well being positive factors, particularly for the international locations 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 world turmoil, the highly effective and trusted management of the well being group 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 an important 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 folks from local weather extremes, and ending our fossil gasoline habit – to create a fairer, safer, and more healthy future for all.”
