The report finds that August 2026 saw widespread above-average temperatures across the U.S., with an average anomaly of 1.6°F across 192 cities. The Southwest was the hottest region, and 39 cities recorded one of their top-five hottest Augusts on record. Long-term trends show August warming since 1970 in 187 of the 192 analyzed locations, with Reno, Nevada, seeing the largest increase.

The report finds that record-breaking sea surface temperatures in July 2026 across European coasts were driven by human-induced climate change, with some regions experiencing warming that substantially exceeds global averages. These extreme temperatures have triggered marine heatwaves, species range shifts, and increased risks to human health and coastal infrastructure. The analysis indicates that such events would have been virtually impossible in a pre-industrial climate and will continue to intensify as global warming progresses.

Analysis of 243 to 247 major U.S. cities reveals that 95% have seen an increase in unusually warm summer nights since 1970, with an average increase of 24 nights per summer. Using the Climate Shift Index (CSI), the report finds that human-caused climate change now strongly influences an average of 27 warm summer nights per year, compared to just one in the 1970s. The most severe impacts are concentrated in Florida and Puerto Rico, where some cities experience over two months of climate-driven warm nights annually. These trends exacerbate heat stress, disrupt sleep, and increase energy demand for air conditioning, disproportionately affecting vulnerable populations and those in urban heat islands.

Analysis of cooling degree days (CDD) shows that 97% of 241 major U.S. cities experienced increased cooling demand since 1970, with an average increase of 37%. This trend, combined with a 31% rise in residential electricity prices between 2020 and 2025, increases the financial burden on households, particularly low-income families. In 2020, the ten states with the highest cooling costs saw average household expenditures between $378 in Hawaii and $712 in Arizona. Future projections suggest U.S. household cooling demand will rise 43% by 2050. The report also highlights systemic risks, including electricity grid strain, increased carbon emissions from fossil-fuel-reliant cooling, and the urban heat island effect caused by waste heat from air conditioners.

The report analyzes the July 2026 wildfires in France and Spain, finding that anthropogenic warming significantly increased the probability and intensity of the fire-conducive weather. In central Spain, similar conditions are now at least 20 times more likely than in a pre-industrial climate, while in southwest France, they are at least twice as likely. The study highlights a 'weather whiplash' pattern where above-average winter rainfall promoted biomass growth, followed by extreme heatwaves and drought that dried fuels. The impact was exacerbated by high human exposure due to population growth in the wildland-urban interface and the presence of flammable maritime pine monocultures in France. The fires caused severe air quality degradation, with PM2.5 levels in Bordeaux exceeding 'fair' thresholds by a factor of 20, leading to the first-ever distribution of the French strategic national reserve of FFP2 masks during an ambient pollution episode.

The U.S. experienced 12 billion-dollar weather and climate disasters from January to June 2026, causing at least $31.9 billion in damages and 183 fatalities. This period ranks fifth for the most events in the first half of any year since 1980. Severe storms were the dominant disaster type, accounting for eight of the 12 events. Historically, the average number of such disasters per year has risen from three in the 1980s to 20 events annually between 2016 and 2025, with the average time between events shrinking from 82 days to 16 days in the same comparison.

The document reports that non-fossil sources reached a record 46.2% of the global electricity mix in April, with wind and solar accounting for 21.3%. It discusses how the instability of the Strait of Hormuz has exposed the fragility of fossil fuel supply chains, prompting countries like China, Poland, and the Philippines to accelerate electrification and renewable energy adoption. Despite this, global fossil fuel subsidies are expected to exceed USD 1 trillion this year, and major energy firms like Shell and BP are pivoting back toward traditional oil and gas models. The text also notes the climate risks evidenced by record heatwaves in Europe and record global carbon emissions in 2025.

Since the 1970s, the global average number of dangerous humid heat days—defined as those with a maximum wet-bulb temperature of 25°C or higher—has more than doubled, rising from 10 to 23 days per year. Climate Central's analysis indicates that human-caused climate change is now the primary driver of this trend, accounting for 64% of all such days since 1970 and 83% of the 23 dangerous days recorded in 2025. The most significant increases are observed in tropical humid regions, including Southeast Asia, coastal West Africa, and tropical South America, though increases are also noted in drier areas like the Arabian Peninsula and the southwestern United States.

Climate Central's analysis of weather data from 1970 to 2025 shows that all four Grand Slam tennis tournaments have experienced an increase in hot days (defined as $\ge$28°C). The French Open has warmed the fastest, with average temperatures rising by 3.5°C. Climate change is attributed with adding 160 extra hot days across the four events, with the U.S. Open seeing the highest absolute increase. Additionally, the frequency of heavy rain days ($\ge$10mm) has increased for the French Open, Australian Open, and Wimbledon.

The share of gas in the global power mix fell for the fifth consecutive year in 2025, dropping from 23.9% in 2020 to 21.8%. While absolute global gas generation has not yet peaked, its growth rate slowed from 2.9% (2016-2020) to 1.6% (2021-2025) as solar and wind met approximately 68% of global electricity demand growth over the last five years. By 2025, 61 out of 124 gas-generating economies had passed their historical gas generation peaks. In the G7, renewable power (2,544 TWh) nearly equaled gas power (2,577 TWh) in 2025. Conversely, gas remains central to the power sectors of the US and Canada, and continues to support demand in parts of North and West Africa.

The briefing identifies a systematic 'escalation of doubt' strategy used by disinformation actors to minimize the role of climate change in wildfires. It details how narratives shift from attributing fires to criminal acts or government mismanagement to more extreme conspiracy theories, such as claims that fires are started to clear land for wind farms or lithium extraction. The document highlights the role of digital platforms' 'attention economy' in amplifying these lies, noting that in Canada, such disinformation has interfered with emergency services and public safety during crises. It concludes that 86% of Canadians support a federal plan to regulate the spread of climate disinformation during extreme weather events.

African ClimateTech has grown significantly, with funding increasing from $206 million in 2016 to over $1.5 billion in 2025, now accounting for nearly 40% of all disclosed venture funding on the continent. However, this growth is highly concentrated: the top 10 companies raised as much as all other companies combined, and Energy accounts for roughly 65% of total funding. The report argues that the ecosystem is not a single market but a collection of applications maturing at different speeds. Energy Generation has reached 'Early Maturity,' while Mobility & Transport is in 'Late Frenzy.' Conversely, Water Access and Built Materials remain in 'Irruption.' A critical finding is that financial maturity, rather than technological readiness, is the primary constraint, with significant gaps in early-stage equity and working capital. The report advocates for 'tailored capital stacks' that combine grants, equity, and debt based on the specific maturity stage of each application.

The 17th edition of the Banking on Climate Chaos report finds that the world's largest banks committed $906 billion to fossil fuel companies in 2025, an 8% increase from 2024. Financing for fossil fuel expansion rose by over 27% to $508 billion. The report highlights a high concentration of finance, with a 'Dirty Dozen' of banks providing nearly 39% of global fossil deals. It also notes a trend of policy backsliding, where banks are weakening climate commitments and abandoning net-zero targets, particularly in the US. The report argues that this financing amplifies energy instability and inequality, especially during geopolitical crises like the 2026 US-Israel war on Iran.

In 2025, global coal capacity additions reached 97.4 GW, the second-highest on record, primarily driven by China and India, even as global coal-fired electricity generation declined by 0.6%. The report highlights a decoupling where coal is increasingly used as system insurance rather than primary generation, as wind and solar displace coal. While China and India dominate new development, coal activity elsewhere is shrinking and becoming more isolated. However, net capacity outside China rose by 5 GW due to a slowdown in retirements and rebounds in India.

A World Weather Attribution study finds that climate change has shifted extreme heat earlier into the year in Saudi Arabia, making May temperatures in Mecca as dangerous as summer temperatures were between 1970 and 1990. The analysis indicates that peak May temperatures are now approximately 2°C hotter and average May temperatures are approximately 3.5°C higher than in a preindustrial climate. This trend increases the risk of heat stroke and exhaustion for millions of pilgrims, with projections suggesting that if global temperatures rise by 3°C, 97% of Hajj pilgrimages would occur during periods of dangerous heat.

Climate Central analysis shows that 14 of the 16 host stadiums for the 2026 World Cup are experiencing more extremely hot days during the June-July tournament period than in 1970. Human-caused climate change is responsible for an average of 49% of these extreme heat days across all stadiums, with the highest impact seen in Miami and Mexico City. In 10 repeat host cities, the frequency of extremely hot days has tripled on average since they last hosted the tournament.

Africa has experienced significant technological leapfrogging by bypassing fixed-line telecommunications in favor of mobile networks. While mobile subscriptions surged from 1.9 to over 100 per 100 people between 2000 and 2023, fixed broadband remains limited. The report highlights the role of satellite internet, such as Starlink, in reaching remote areas and notes that mobile broadband coverage in Nigeria is linked to increased household consumption and poverty reduction. By 2050, mobile phone and mobile broadband subscriptions are projected to reach 150 and 149 per 100 people, respectively, though gaps in affordability and digital skills persist.

Africa has seen infrastructure improvements, particularly in sub-Saharan Africa, but continues to face a substantial deficit driven by population growth and urbanisation. Financing is characterized by a tension between concessional Western multilateral loans and more commercial, opaque Chinese lending via the Belt and Road Initiative. Recent efforts, such as the PIDA framework and the 2025 Africa Infrastructure Financing Summit, aim to align investment with pan-African priorities and global sustainability goals, including a transition toward renewables and electric mobility.

The study finds that anthropogenic climate change approximately tripled the probability of the April 2026 heatwave in northwestern India and Pakistan, making it about 1°C hotter than it would have been in a preindustrial climate. Analysis indicates that extreme heat is occurring earlier in the season, with the likelihood and intensity of April events increasing more rapidly than those in May. This trend extends the period of dangerous heat exposure for hundreds of millions of people, compounding risks to health, agriculture, and the economy. The report also highlights systemic vulnerabilities, noting that heatwaves are not officially declared disasters in India and Pakistan, which limits access to relief funding.

The report finds that British power prices are becoming increasingly independent of gas, with 15% of generation already de-linked via the Contracts for Difference (CfD) scheme. This proportion is forecast to rise to 36% by 2030. The document highlights that high renewable generation, particularly wind and solar, significantly lowers wholesale prices; in 2025, hours where gas was below 20% of the mix averaged £60/MWh, compared to £130/MWh when gas exceeded 50%. Recent data from March and April 2026 shows record wind and solar generation displacing gas during a period of geopolitical conflict and fuel price spikes.
