Climate Central analysis of 204 U.S. cities shows that the first fall freeze is arriving later in 88% of locations, delaying the date by an average of 12 days since the early 1970s. This trend extends the growing season for ragweed, prolonging allergy seasons, and disrupts ecological cues for bird migration, hibernation, and fall foliage. Additionally, the delay affects the $27 billion U.S. fruit and nut industry by reducing necessary chilling periods and allowing disease-carrying insects like mosquitoes to persist longer into the year.

In the first half of 2025, global solar and wind generation grew sufficiently to meet and exceed total electricity demand growth, leading to renewables overtaking coal in the global electricity mix for the first time. Solar generation saw record absolute growth, while total fossil fuel generation declined slightly. Consequently, global CO2 emissions from the power sector fell marginally by 0.2%, although results varied by region, with emissions decreasing in China and India but increasing in the US and EU.

The document argues that UK local authorities have a solid legal foundation under the Road Traffic Regulation Act 1984 to implement weight- or size-based parking tariffs for SUVs. It highlights that SUVs increase fatality risks for pedestrians and cyclists, contribute more to air pollution via tyre and brake wear, and cause greater road surface damage. To avoid legal challenges, the briefing advises councils that such charges must be justified by traffic management and safety goals rather than revenue generation, and must be supported by robust public consultation.

The report analyzes the role of nominee companies—middlemen that hold shares in name only—in masking the identities of investors in Australian coal, oil, and gas projects. It finds that these structures obscure approximately 18% of Australia's national fossil fuel CO2 emissions and are predominantly operated by major global banks. The document highlights a lack of regulatory requirements for nominee disclosure in Australia, which allows investors, including some superannuation funds, to maintain stakes in high-emitting assets while avoiding public scrutiny.

The report proposes a cost-optimal energy pathway for Thailand that exceeds the Revised Power Development Plan (RPDP) targets by adding 32 GW of solar and 6 GW/15 GWh of battery storage by 2037. This shift would result in cumulative cost savings of $1.8 billion and avoid 147 million tonnes of CO2 emissions. The analysis suggests that Thailand can meet its demand without adding 2 GW of planned natural gas capacity, as solar and batteries can cover growth from data centres and EV charging. While wind power is deemed financially unviable unless capital expenditures drop by 10% annually, the report suggests importing hydropower from Lao PDR as a cost-effective alternative to wind, despite risks related to import dependency and climate-driven droughts.

Canada is on track to miss its 2030 climate target due to rising oil and gas emissions and weakened policies. The Canadian Climate Institute argues that continuing to reduce emissions is essential for economic competitiveness and reducing climate damages, which currently equal about half of the year's expected GDP growth. Recommended actions include modernizing industrial carbon pricing, enacting the Clean Electricity Investment Tax Credit, finalizing methane regulations, and improving disaster resilience for housing.

Between June and August 2025, human-induced climate change significantly increased global temperatures, with at least 22% of the global population experiencing temperatures at Climate Shift Index (CSI) level 2 or higher every day. Nearly 955 million people faced 30 or more 'risky heat days' added by climate change, with the highest impact seen in Asia. The report also documents severe climate-driven events, including record rainfall and flooding in China, India, Pakistan, and the U.S., as well as historic wildfires in Europe and Canada.

Climate Central's analysis for June to August 2025 reveals that at least 22% of the global population experienced temperatures made at least twice as likely by climate change daily. In the U.S., over 21 million people in 32 cities faced 30 or more 'risky heat' days added by climate change, with some cities, such as Honolulu, seeing all their risky heat days attributed to human-caused warming.

China's historical economic growth, driven by a six-fold increase in coal consumption, is now constrained by high import dependence on oil and gas, dwindling coal reserves, and severe environmental costs including carbon emissions that account for one-third of the global total.

The report finds that while a majority of registered U.S. voters support various clean energy policies and prefer candidates who take action on global warming, the issue remains low in priority for most voters when deciding on congressional candidates. There is strong bipartisan support for policies like soil restoration and renewable energy research, but significant polarization exists regarding the transition from fossil fuels and the Paris Climate Agreement.

The policy brief outlines how climate change and historical land management have increased wildfire risk across Canada, leading to record-breaking seasons and significant financial losses. It proposes five key government interventions: restricting development in high-hazard zones, mandating fire-resilient building codes, implementing fuel management and Indigenous cultural burning, increasing firefighting capacity, and accelerating carbon emission reductions.

A coalition of environmental organizations argues that Arendalsuka, a major Norwegian democratic festival, should drop Equinor as a sponsor. The authors claim Equinor is one of 36 'fossil giants' responsible for over half of global CO2 emissions and accuse the company of using 'petroganda' to manipulate public perception. They highlight that in 2023, only 0.15% of Equinor's total production was renewable energy, contrasting this with the company's image as a pioneer in low-carbon solutions. The statement further notes that Equinor spent 833 million NOK on sponsorships over the last five years to preserve its image.

GadgetroniX installed a 6.48 kWp off-grid solar system with battery storage and hybrid inverter technology at Lekule Secondary School in Arusha, Tanzania. The system, which includes JA Solar panels and a 20 kWh Freedom Won battery, replaced a reliance on inconsistent grid electricity and fossil fuel generators. This transition has enabled students to study after dark, reduced the school's carbon emissions, and lowered operational expenses.

GadgetroniX installed a 9.72 kWp off-grid solar system with battery storage and remote monitoring at Matale Secondary School in Tarime, Tanzania. The project addressed frequent power outages and dependence on expensive energy alternatives, resulting in a 40% reduction in energy costs and the provision of uninterrupted power for students and administrative operations.

Mighty Earth calls for a full veto of Brazil's "Devastation Bill," arguing that the legislation would weaken environmental licensing and safeguards for the Amazon, Cerrado, and Pantanal biomes. The statement highlights that the bill contradicts Brazil's international pledges to achieve zero deforestation by 2030 and would undermine the country's credibility ahead of hosting COP30 in Belém.

The document is a quick start guide for the Energy Policy Simulator (EPS), a tool developed by Energy Innovation to help users model state-level energy systems and climate policies. Using Louisiana as an example, it explains how to access the simulator, apply specific policies such as a Clean Electricity Standard or Building Component Electrification, and analyze results through CO2e emission graphs and wedge diagrams. It also describes how to use pre-designed scenarios, including the NDC Scenario and the Federal Policy Repeal and Rollback scenario, to test different decarbonization pathways.

The Trump administration has initiated the process to reopen the Powder River Basin in Wyoming and Eastern Montana for new coal leasing, reversing a 2024 Interior Department decision that halted leasing due to declining demand and the climate crisis. Earthjustice contends that this move, alongside a budget bill slashing coal royalty rates and mandating permit approvals, prioritizes corporate profits over public health and climate goals. The briefing notes that wind and solar power surpassed coal in the U.S. in 2024 and warns that coal mining continues to threaten the air, water, and health of frontline communities, including the Northern Cheyenne Tribe.

The Amazon Soy Moratorium (ASM), established in 2006, prevents the purchase of soy grown on land deforested after 2008 in the Amazon biome. Between 2009 and 2022, deforestation dropped by 69% in monitored municipalities. Signatories argue that dismantling the ASM would unlock 1.1 million hectares for soy cultivation, potentially releasing 300 million tonnes of CO₂ within 1 to 2 years and opening approximately 10 million hectares of deforested land to soybean cultivation. The pledge calls for continued adherence to the 2008 cut-off and urges Brazilian authorities to maintain the ASM to align economic development with environmental stewardship.

Drax power station is the UK's largest carbon emitter, with 2024 emissions of 13.3 million tonnes of CO2e, a 16% increase over the previous year. Despite the complete phase-out of coal power in September 2024, biomass and gas plants continue to dominate the top emitter rankings. Drax is projected to remain the largest emitter through 2030, even with planned subsidy cuts starting in 2027. Other significant emitters include Port Talbot Steelworks and Pembroke gas power station, while carbon capture deployment across the UK's largest industrial sites has seen limited progress.

Analysis of 247 major U.S. cities shows that under high-emissions scenarios, summer high temperatures are projected to increase by an average of 3.6°F by 2060 and 7.9°F by 2100. For many cities, these future conditions will resemble current climates in locations hundreds of miles to the south, with 16 cities projected to reach temperatures only currently found in Pakistan, the Middle East, and North Africa.
