In 2024, the EU power sector saw fossil fuel generation fall to its lowest level in over forty years, reaching 793 TWh. This decline was driven primarily by record solar growth, which saw generation increase by 22% to 304 TWh, overtaking coal for the first time. Renewables accounted for 47% of EU power generation, while clean sources reached a record 71% of the mix. Despite a small 1% increase in total EU power demand and increased exports to the UK and Ukraine, coal and gas generation fell by 16% and 6% respectively, leading to a 9% drop in power sector emissions to an estimated 585 million tonnes of CO2.

In 2024, the EU's electricity transition continued with solar power overtaking coal for the first time and gas generation declining for the fifth consecutive year. Renewables reached a 47% share of the power sector in 2024, up from 34% in 2019, while fossil fuels dropped to a historic low of 29%. This shift reduced power sector emissions to less than half of their 2007 peak and avoided €59 billion in fossil fuel imports since the start of the European Green Deal. Despite this momentum, the report argues that wind power deployment and grid infrastructure must accelerate to meet 2030 targets.

In 2024, the EU experienced record growth in solar generation and capacity, with all member states seeing increases. However, the rapid expansion has led to more frequent zero or negative power prices and wider intraday price spreads. To manage this and maintain the trajectory toward 2030 targets, the report advocates for the accelerated rollout of clean flexibility tools, specifically battery storage, smart electrification, and grid modernization.

Climate Central analyzed 245 U.S. locations and found that winter is the fastest-warming season for 76% of these sites, particularly in the Northeast, Southeast, and Ohio Valley. In the western U.S., fall and spring were the fastest-warming seasons for 31 locations, while some West and Northwest areas experienced the most rapid summer warming. These trends contribute to disrupted snowfall, earlier snowmelt, increased wildfire intensity, and longer pest and allergy seasons.

The study identifies increasing dryness in the Coquimbo region of Chile, particularly during spring and summer, noting that the frequency and duration of extreme dry events have increased over recent decades.

In 2025, US solar generation increased by 83 TWh, meeting 61% of the 135 TWh rise in electricity demand. This growth was most concentrated in regions with the highest demand increases, such as Texas and the Midwest. While utility-scale solar capacity additions fell by 6% due to tariff uncertainties and grid connection delays, battery capacity surged by 133% to 26 GW, enabling solar to meet some evening demand and reducing curtailment pressure, particularly in California.

The text emphasizes that Brazil's vast size and climatic diversity require detailed observational studies to distinguish between natural variability and long-term climate change. It highlights that interannual variability, driven largely by El Niño and La Niña, can alter seasonal rainfall in the Amazon by a factor of more than four. The author cautions that most precipitation trends in Brazil are linked to interdecadal oscillations—such as the Atlantic Multidecadal Oscillation (AMO) and the Interdecadal Pacific Oscillation (IPO)—rather than global warming. Additionally, the document notes a trend of increasing air temperatures in the tropics of South America since 1948, contrasting with a negative trend in the subtropics since the mid-1990s, and mentions the influence of land-use change and biomass burning on air temperature in the Amazon and Cerrado.

In Q4 2024, US utilities updating their IRPs reduced planned wind and solar capacity by 20 GW and increased planned gas capacity by 12 GW, leading to an 8 percent increase in projected emissions despite a small downward adjustment in projected load.

Analysis of the CARIACO station (1996–2013) reveals a significant increase in sea surface temperature, a decrease in pH, and a decline in chlorophyll a and phytoplankton abundance, alongside a reduction in upwelling intensity linked to lower wind speeds.

The study analyzed chlorophyll concentrations from 1997 to 2017 using SeaWiFS and MODIS Aqua data across four Large Marine Ecosystems (LMEs). It found significant increases in chlorophyll concentrations in large portions of the Patagonia (PLME) and Humboldt (HLME) ecosystems, while increases in the South Brazil (SBLME) and Pacific Coastal Central America (PCACLME) ecosystems were limited to smaller regions.

The report identifies five key trends in the development of the U.S. electric vehicle workforce pipeline, focusing on Georgia, Michigan, Nevada, North Carolina, and Tennessee. It finds that public community and technical colleges are the primary providers of training, with a heavy emphasis on vehicle maintenance and repair over manufacturing and charging. The analysis highlights a wide variance in enrollment requirements and program durations, ranging from 20-hour online courses to two-year degrees. It also identifies three critical industry certifications—ASE, AWS, and NIMS—and describes how state-level policies and private investments are driving the creation of these educational pathways to support the transition to zero-emission vehicles.

The energy transition accelerated in 2024, driven by record uptake in solar, wind, and electric vehicles as costs for solar modules and batteries fell significantly. While renewables are poised to overtake coal as the leading power source in 2025 and many nations have set net-zero goals, progress in energy efficiency and methane reduction remains off track. The document argues that achieving 2030 targets requires shifting fossil fuel subsidies toward clean energy investments, particularly in emerging economies.

The study identifies divergent sea surface temperature trends around southern South America between 1982 and 2017, with warming in mid-latitude regions and the Northern Patagonian Shelf, and cooling south of 50°S and on the Southern Patagonian Shelf. These trends became most significant between 2008 and 2017 and are linked to atmospheric forcing and large-scale climate modes including ENSO, the Interdecadal Pacific Oscillation, and the Southern Annular Mode.

Analysis by Climate Central shows that all 50 U.S. states and 99% of 242 analyzed major cities have warmed since 1970. Alaska was the fastest-warming state, while Reno, Nevada, experienced the highest city-level temperature increase. The document links these trends to rising greenhouse gas concentrations, which reached 427 ppm of CO2 in 2025, and advocates for the transition to zero-emission vehicles, solar and wind power, and heat pumps to mitigate future risks.

The document examines how rising temperatures increase the speed and frequency of thunderstorm straight-line winds, particularly in the central U.S., and projects an increase in the occurrence of large-scale derecho events.

Global climate finance reached a record USD 1.9 trillion in 2023, with private contributions exceeding USD 1 trillion for the first time. While mitigation finance more than doubled between 2018 and 2023, driven by energy and transport, adaptation finance remains significantly underfunded at USD 65 billion. Investment is heavily concentrated in East Asia and the Pacific, Western Europe, and North America, with 80% of finance sourced domestically. Despite growth, a substantial gap remains to meet the estimated annual need of USD 6.3 trillion by 2030.

Climate finance in Brazil more than doubled between 2019 and 2023, reaching US$ 67.8 billion. The growth was primarily driven by solar energy and AFOLU (Agriculture, Forestry, and Other Land Use), with domestic sources accounting for 90% of total finance. While mitigation dominates the objective mix, finance for loss and damage saw an exponential increase in 2024, largely due to disaster relief following flooding in Rio Grande do Sul.

The report presents findings from the 2025 IPIE Expert Survey, highlighting a growing pessimism about the future of the information environment. It identifies the availability of accurate information and diverse voices as essential for a healthy environment, while citing lack of platform accountability as a primary threat. The document also examines the mixed impact of social media, the negative perceptions of generative AI, and the increasing barriers faced by researchers, particularly regarding funding and academic freedom.

The report finds that 80% of countries with competitive national elections in 2024 experienced GenAI-related incidents, with 69% of these incidents having a harmful impact. The majority of GenAI use focused on content creation (90%), and nearly half of the incidents (46%) had unknown sources. While some positive uses for civic engagement were noted, the document emphasizes the risks of disinformation and foreign interference, calling for mandatory disclosure standards and improved detection mechanisms.

As of 2025, almost every developing country has initiated a National Adaptation Plan (NAP) process, with 71 countries having submitted multi-sector NAPs since 2015. The most common climate hazards identified in these plans are droughts, floods, and changes in precipitation, while the primary priority sectors are agriculture, health, and water/sanitation. While 100% of NAPs mention monitoring, evaluation, and learning (MEL), only 65% include a cost estimate for implementation, with estimates ranging from USD 1.4 million to USD 349 billion. Gender and social inclusion are integrated to varying degrees, with women and youth being the most frequently mentioned social groups.
