Analysis of NOAA data shows that all 50 U.S. states and 99% of 242 analyzed cities have warmed since 1970. Alaska was the fastest-warming state (+4.3°F), while Reno, Nevada, saw the highest city-level increase (+7.8°F). The contiguous U.S. has warmed by approximately 2.8°F, exceeding the global warming limit of 2.7°F (1.5°C). The document advocates for a clean energy transition through zero-emission vehicles, solar and wind power, and heat pumps to mitigate these trends.

In 2024, clean power reached a milestone of 40.9% of global electricity generation, driven by a record surge in solar and a rebound in hydropower. Despite this growth, global power sector emissions reached a record high of 14.6 billion tonnes of CO2 because extreme heatwaves drove a 4.0% increase in electricity demand, forcing a 1.4% rise in fossil fuel generation to meet the additional cooling needs.

The document analyzes how climate change disrupts agricultural yields and trade flows, particularly in developing regions, while contributing significantly to global GHG emissions. It highlights the risks of food insecurity and the potential for trade-related climate measures to marginalize vulnerable economies. The author argues for a comprehensive international cooperation agenda focused on reducing trade tensions, reforming harmful subsidies, facilitating technology transfer, and securing global food stocks to ensure a fair transition to sustainable agriculture.

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 report finds that 10 major international oil companies (IOCs) are responsible for 7% of global gas flaring on an equity-weighted basis, with a significant portion occurring at non-operated assets. In 2023, total global upstream flaring was 145 billion cubic meters (bcm), with an average intensity of 5.0 m³/bbl. The analysis highlights a gap between corporate commitments to the World Bank's Zero Routine Flaring (ZRF) initiative and actual performance, noting that non-routine flaring remains largely unabated and that no analyzed company meets the IEA's Net Zero Emissions scenario target of 0.3 m³/bbl by 2030. The report argues that IOCs have a broader influence on up to 40% of global flaring through their partnerships with national oil companies (NOCs) and recommends extending emissions targets to non-operated assets and implementing stricter regulatory and financial levers.

The document details how human activities, primarily the burning of fossil fuels, have increased atmospheric concentrations of carbon dioxide, methane, and nitrous oxide to levels higher than any point in the last 800,000 years. These gases have caused a combined 1.6°C of global warming since 1850, with CO2 and methane accounting for 95% of this increase. In the United States, 76% of greenhouse gas emissions originate from three sectors: transportation (28%), electric power (25%), and industry (23%). The text emphasizes that while the U.S. has reduced emissions to approximately 17% below 2005 levels, the pace of reduction must more than triple to meet 2030 national targets.

The study estimates that Lagos State has approximately 19 GW of genset capacity, producing 39 million tons of CO2 equivalent annually. High upfront costs are the primary barrier to solar adoption, despite strong interest from households and MSMEs. The report advocates for lease-to-own models and standardized solar designs to replace petrol and diesel generators.

This policy brief argues that the current reliance on a single 100-year metric for greenhouse gas emissions obscures the distinct warming impacts of methane and carbon dioxide. The author advocates for a "multi-basket" approach with separate targets and dual metrics to address both short-term and long-term climate risks, asserting that simultaneous mitigation of both pollutants is essential to meet global temperature targets and reduce climate overshoot.

The Net Zero Stocktake 2024 reveals a consolidation of net zero targets across countries, cities, and companies, but highlights a critical gap in integrity. While national targets now cover 87% of global GHG emissions, fewer than 5% of non-state entities meet all minimum procedural and substantive integrity criteria. The report emphasizes that national targets often act as a 'ceiling' for subnational ambition, though some regions in countries like Australia and Japan have historically pushed national goals forward. It also notes that members of the Race to Zero campaign generally outperform non-members on integrity measures, although absolute performance remains low.

The report examines the intersection of climate change and democratic processes, detailing how extreme heat, floods, and wildfires disrupt voter registration, polling access, and ballot counting. It provides evidence of recent climate-driven disruptions in the US, India, and Pakistan, and analyzes temperature anomalies in 60 countries during the 2024 election cycle. The authors advocate for systemic changes, such as flexible voting arrangements, improved risk mapping, and updated emergency statutes, to protect the fundamental right to vote on a warming planet.

The analysis finds that human-caused climate change has significantly increased the frequency of dangerous nighttime temperatures globally, affecting billions of people. Using the Climate Shift Index, the report quantifies additional nights above 18°C, 20°C, and 25°C, noting that these temperatures disrupt sleep and increase risks of cardiovascular conditions and mortality. The most severe impacts are observed in tropical regions and urban areas due to heat island effects, with specific cities in India, Indonesia, and Africa experiencing an additional month or more of extreme nighttime heat.

The report analyzes seven categories of enclosure-based and open measurement methods for greenhouse gas emissions in sanitation systems. It finds that while enclosure-based methods like flux chambers are widely used, they are limited by scale. Emerging optical and remote sensing methods offer broader coverage but are constrained by high costs. The document highlights a critical lack of empirical data for non-sewered sanitation in low- and middle-income countries and advocates for standardized, affordable methodologies and increased collaboration to improve national greenhouse gas inventories.

The report critiques the GWP* (Global Warming Potential Star) metric, arguing that while it may be useful for specific climate modeling, its application to national or sectoral policy is unfair and scientifically misleading. Unlike the standard GWP, which uses a zero-emission baseline, GWP* evaluates current emissions relative to past levels, potentially rewarding countries with historically high emissions and penalizing developing nations. The authors contend that this approach can be used to justify continued methane pollution, particularly in the livestock sector, and advocate for a 'multi-basket' approach that sets separate targets for short-lived pollutants like methane and long-lived gases like CO2 to ensure equitable and effective climate action.

In April 2024, fossil fuel generation in the EU fell to a record monthly low of 23%, with coal and gas both seeing significant declines. This shift was driven by record-high wind and solar output, which together provided 34% of electricity, and a recovery in hydropower. Consequently, the EU power sector's emissions in April reached a record low of 38 million tonnes of CO2, contributing to an 18% year-on-year decrease in emissions for the first four months of 2024 despite a slight recovery in electricity demand.

Since 1970, 98% of analyzed U.S. cities and all 50 states have warmed, with Reno, Nevada and Alaska experiencing the fastest increases. To combat this, U.S. clean technology investment reached a record $239 billion in 2023, more than tripling since 2018, with South Carolina and Nevada leading in investment as a percentage of GDP, primarily driven by battery manufacturing.

The document examines the EPA's proposed use of hydrogen co-firing to set CO2 emission limits for fossil fuel-fired power plants under the Clean Air Act. It warns that unless the hydrogen used is 'low-GHG', the process could increase total emissions, as common production methods like steam methane reforming or fossil-fuel-powered electrolysis release significant greenhouse gases.

The guide describes how spectrometers on satellites detect the infrared signature of methane to identify emissions from oil and gas, coal, waste, and agriculture. It highlights the emergence of NGO-led missions like MethaneSAT and Carbon Mapper, which provide open-source, granular data to drive climate action and pressure emitters to reduce leaks.

Eight young people sued the State of Florida, arguing that the state's fossil fuel-based energy system violated their constitutional rights to life, liberty, property, and the pursuit of happiness. The plaintiffs claimed that human-caused carbon dioxide concentrations would impair vital natural resources and discriminately harm current and future generations. Both the Circuit Court for the Second Judicial Circuit and the First District Court of Appeal dismissed the complaint, ruling that the issues were non-justiciable political questions that must be resolved by the political branches of government rather than the judiciary, citing the separation of powers doctrine.

The document highlights that 2023 is virtually certain to be the hottest year on record, driven by human-caused greenhouse gas emissions. It details the resulting increase in extreme weather events, the long-term trend of rapid warming since the industrial revolution, and the necessity of transitioning to clean energy to meet global climate targets.

The EU ETS will expand to shipping in 2024, applying the 'polluter pays principle' to cargo and passenger ships of 5,000 gross tonnage and above. The system covers 100% of emissions for voyages between EU ports and 50% for voyages between EU and non-EU ports. Costs will be phased in, starting with 40% of 2024 emissions paid in 2025, reaching 100% by 2027. While CO2 is covered from 2024, methane and nitrous oxide will be included from 2026. Revenue will support the Innovation Fund and member state climate projects, with specific exemptions for ice-traveling ships, certain outermost regions, and small island ferries until 2030.
