A new assessment from the UN Environment Programme’s Emissions Gap Report 2025: Off Target shows that a decade of climate policy under the Paris Agreement has shaved projected warming this century from roughly 3–5°C down to about 2.3–2.5°C, if all national climate pledges are fully carried out. That is progress, but the report and a companion UNEP press release warn that the window to keep 1.5°C alive is now measured in just a few years, and a temporary overshoot of that limit is described as “inevitable”. The gap between today’s policies and what science demands remains enormous: current measures still point towards about 2.8°C of warming. Meanwhile, climate impacts and the economic damage they cause are already accelerating, with weather and climate extremes costing the EU nearly €45 billion per year in the early 2020s, according to the European Environment Agency. With COP30 approaching, the UN is blunt: only unprecedented, immediate cuts in fossil fuel use can prevent this trajectory from hardening into full-blown climate breakdown.
For decades, the US Environmental Protection Agency allowed heavy industrial polluters to estimate their own emissions of cancer-causing chemicals instead of measuring what actually drifts into nearby neighborhoods. A new ProPublica investigation based on fence-line air monitoring around 20 large facilities finds that real-world pollution was almost always higher – and sometimes tens to more than a thousand times higher – than what companies reported, meaning millions of people may face far greater cancer risks than regulators assumed. The Biden administration responded in 2024 with rules requiring steel, coke and chemical plants to install permanent monitors, but President Trump’s EPA has now moved to delay and weaken those protections while granting dozens of plants temporary exemptions. Residents in industrial towns from western Pennsylvania to Louisiana’s “Cancer Alley” say the stakes are life-or-death, and public health experts warn that every year of inaction locks in avoidable disease and early deaths.
The latest United Nations “Emissions Gap” analysis shows that even after a new round of climate pledges, the world is still heading for around 2.3–2.5°C of warming this century if governments actually deliver on their promises – and as much as 2.8°C if they merely continue with today’s policies. The apparent improvement since last year’s report is tiny, and part of it is wiped out by the planned withdrawal of the United States from the Paris Agreement and sweeping rollbacks of US climate rules. At the same time, 2024 was the hottest year ever recorded, with global temperatures hovering around 1.5°C above pre-industrial levels. Scientists now say that crossing the Paris 1.5°C limit on a long-term basis is “very likely” within the next decade unless emissions fall sharply, locking in deadlier heat, rising seas and irreversible damage.
From zoning rules to bus routes and school budgets, state and local officials quietly make decisions every week that lock in climate pollution — or slash it. When national politics are paralyzed, these smaller arenas often become the real front line of climate action. A recent radio story from Yale Climate Connections, featuring U.S. Representative Mike Quigley, stresses that every elected office matters, down to school and library boards Why talking to your state and local leaders matters. Instead of only signing online petitions, he urges people to build personal relationships with their representatives and their staff. Research on local climate policy shows that cities and regions can deliver faster, cheaper emission cuts with major health and economic benefits. The message is clear: in a rapidly closing climate window, your voice at town hall can be just as critical as any vote in Congress.
A decade after the Paris Agreement was signed, the latest United Nations Environment Programme Emissions Gap Report 2025 delivers a stark verdict: the world is still racing toward dangerous levels of warming while governments drag their feet. Global greenhouse gas emissions hit a record 57.7 billion tonnes of CO2-equivalent in 2024, rising 2.3 per cent in just one year, even as climate impacts intensify and low-income countries bear the brunt of the damage. New national climate pledges for 2035 shave only a few tenths of a degree off projected warming, leaving the planet heading for roughly 2.3–2.5°C this century if promises are fully implemented – and closer to 2.8°C based on current policies. According to the report, the world will very likely overshoot 1.5°C within the next decade unless emission cuts accelerate dramatically, making deep and immediate action a life-or-death race against time. The full findings are published in the Emissions Gap Report 2025: Off target.
A new perspective from the Carbon Literacy Project argues that climate action hasn’t slipped off the public agenda, even as politics feel polarised. The World Economic Forum’s latest Global Risks Report 2025 ranks extreme weather as the top 10-year risk and urges renewed collaboration. Recent events like Hurricane Melissa’s devastation across Jamaica, Haiti and Cuba underline how warmer seas are supercharging storms, with at least 50 deaths reported, according to Reuters. In the UK, the government’s Climate Change Risk Assessment 2022 warns damages will reach at least 1% of GDP by the mid-2040s, while the OBR projects debt could reach roughly 270–340% of GDP in the 2070s if climate damages mount, with some scenarios “around 290%” (OBR 2024). Research from Climate Outreach shows messages linking climate to local health, safety and nature significantly lift support.
UN climate scientists report that atmospheric carbon dioxide jumped by 3.5 ppm from 2023 to 2024—the steepest annual rise since modern measurements began in 1957. Global CO2 now stands around 423 ppm, roughly 52% above pre-industrial levels, with methane and nitrous oxide also at record highs, according to the World Meteorological Organization’s latest greenhouse-gas bulletin. The spike is linked to continued fossil fuel use, exceptional wildfire emissions, and weakening natural “sinks” in oceans and on land during a strong El Niño and the hottest year on record. WMO’s Ko Barrett warned that heat trapped by greenhouse gases is “turbo-charging” extreme weather, urging rapid emission cuts and stronger monitoring. See the WMO media note and full report for details: WMO press release, WMO Greenhouse Gas Bulletin (PDF).
A new peer-reviewed review in the Annual Review of Environment and Resources concludes that most carbon offset programs have delivered little real climate benefit, citing persistent problems with additionality, leakage, permanence and double counting. The paper synthesizes 25 years of research and argues that quality issues are systemic rather than the result of a few “bad apples” Are Carbon Offsets Fixable?. A separate meta-analysis in Nature Communications estimates that fewer than 16% of investigated credits correspond to genuine emission cuts Nature Communications study. Meanwhile, atmospheric CO₂ set new records in 2024, with Mauna Loa’s May average reaching 426.9 ppm NOAA. The voluntary carbon market’s value fell 61% in 2023 as buyers questioned credit quality Ecosystem Marketplace 2024. Reforms led by the Integrity Council’s Core Carbon Principles aim to raise standards ICVCM CCPs.
Solar power has crossed a psychological and economic line. A new analysis from the University of Surrey finds that, in the sunniest markets, utility-scale solar can deliver electricity for as little as £0.02 per unit—cheaper than coal, gas or even wind, thanks to decade-long cost declines and rapid scaling. The study also reports an 89% fall in lithium-ion battery prices since 2010, making solar-plus-storage competitive with gas plants and turning sunlight into a more reliable, dispatchable resource. The authors caution that grids in places like California and China already struggle with midday surpluses, so smarter networks, better forecasting and stronger regional links are essential.

For the first time on record, renewable sources produced more electricity than coal in the first half of 2025, a milestone highlighted by Ember’s mid-year analysis and corroborated by independent coverage from Reuters. The gains were driven largely by solar and wind growth in China and India, which more than covered global demand increases. Yet progress isn’t uniform: the IEA’s new outlook trims its global forecast and cuts the U.S. growth projection by nearly half amid policy rollbacks. The result is a split-screen picture—renewables advancing worldwide while key Western markets wobble—suggesting a fragile but real turning point. For context, see New York Times coverage.
At a wetlands summit near Victoria Falls, U.S. ecologist Gillian T. Davies pressed a radical idea: give wetlands legal rights so courts can protect them before they’re damaged, a strategy gaining traction from Ecuador to Panama. Despite decades of pledges, wetlands keep disappearing—faster than forests—eroding natural flood buffers and carbon stores. Indigenous leaders have long framed nature as a living community; now more Western scientists are joining, bringing data to craft laws and win cases. Politics still slow progress: a Sri Lankan push to encourage “rights of wetlands” was sidelined, and diplomatic squabbles dominated the meeting. Yet momentum is building, as reported by Inside Climate News: The Scientists Making the Case for Nature’s Rights.
An Indigenous land defender, Efraín Fueres, was killed during protests in Ecuador, a stark example of a grim global trend: on average, three environmental defenders are killed or disappear each week. The unrest erupted after the government scrapped a diesel subsidy and imposed a sweeping state of emergency, with reports of troops in communities and communications blackouts. President Daniel Noboa has also moved toward rewriting the constitution, a step critics say could weaken protections for nature and Indigenous peoples. The case highlights how conflicts over land, mining and austerity collide with human rights.
