Warming U.S. Cities Face Higher Cooling Demand and Energy Bills
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.

U.S. clean energy investments: 2025 Quarter 4 analysis
In Q4 2025, U.S. clean energy investments were characterized by significant uncertainty driven by a record 43-day government shutdown, the One Big Beautiful Bill Act (OBBBA), and Department of Energy (DOE) funding cuts. While utility-scale solar and storage remained strong, with $18 billion in actual investments, other sectors like wind, hydrogen, and sustainable aviation fuel (SAF) faced substantial project cancellations. Nuclear energy showed signs of growth through large-scale partnerships and DOE loans, while the manufacturing sector saw $8.4 billion in EV supply chain cancellations, partly due to shifting federal incentives and corporate pivots toward gas and hybrid vehicles.

Power After the Storm
The report analyzes power outage data from 2014 to 2024 in the central United States, specifically the MISO+ region, finding that all of the 100 worst outage days were caused by extreme weather. It highlights that the 10 most severe events occurred after 2020 and were often compound disasters, such as hurricanes combined with flooding or winter storms with tornadoes. The document argues that climate change is intensifying these risks—increasing the frequency of derechos, the rainfall of hurricanes, and the potential for severe winter outbreaks—while disproportionately impacting socially vulnerable communities. It recommends that utilities, states, and regional operators implement comprehensive climate risk assessments, accelerate the clean energy transition, and engage in meaningful community partnership to build a resilient grid.

Neonicotinoid Seed Treatments in North American Row Crops: A Literature Review of Yield and Profitability Outcomes
The review finds that neonicotinoid seed treatments (NSTs) often fail to provide statistically significant increases in yield or profitability for North American farmers, particularly in colder regions like the Midwest and Northern U.S. where early-season pest pressure is lower. While some positive returns on investment (ROI) were observed in the U.S. South due to milder winters and higher pest pressure, these results were inconsistent year-to-year. The document highlights significant ecological harms, including the reduction of predator insect populations, damage to pollinators, and disruption of soil decomposition. It argues that a shift from prophylactic use to an 'assess-and-decide' approach based on actual pest pressure would save farmers money without reducing yields.

Five Things to Know About Climate Change in 2025
The document reports that 2025 is virtually certain to be among the top five hottest years globally, driven by rising carbon pollution from fossil fuels. In the U.S., record high temperatures significantly outpaced record lows, and the year saw a record-costly start for billion-dollar weather and climate disasters, including the most expensive wildfire event on record in Los Angeles. Globally, carbon pollution intensified Hurricane Melissa, which devastated Jamaica. The report also highlights a trend of 'hydroclimate whiplash' contributing to both the Los Angeles fires and deadly flash floods in Texas, while noting that the U.S. has rolled back key clean energy policies and is set to withdraw from the Paris Agreement by January 2026.

Mapping opportunities to decarbonize the U.S. pulp and paper industry
The U.S. pulp and paper industry, which accounts for 9% of industrial energy consumption, offers significant potential for net-negative emissions through CCS due to its reliance on waste biomass. A new mapping tool evaluates facilities based on capture costs, capture potential, storage costs, infrastructure clustering, and co-benefits. The analysis identifies the Gulf Coast—specifically Louisiana, Mississippi, and Texas—as having the highest opportunity scores. While private sector interest is growing, the document argues that the 45Q tax credit requires enhancement and regulatory certainty for transport infrastructure is needed to scale these technologies.

The Next California Phase III: Action and Implementation
The Next California project, now operating through the Delta Ag Alliance, seeks to increase specialty crop acreage in the Mid-Mississippi Delta from 0.19% to 3% by 2034. This transition is designed to unlock $3.2 billion in annual farmgate revenue and protect US food security as climate change forces production shifts away from California. The project employs a four-pillar strategy: farmer-led discovery, innovative funding structures (including operating loans and infrastructure funds), support for farmer-entrepreneurs, and public sector research alignment. Early pilots like Delta Harvest have demonstrated the economic viability of specialty rice, while other ventures like Peebles Organics and Delta Dirt Distillery showcase the potential for organic produce and value-added processing. To scale these efforts, the alliance is focusing on bridging the 'chasm' between early innovators and the early majority through targeted capital and the development of regional processing infrastructure.

Thunderstorm Straight-Line Winds
Severe storms in the U.S. have become significantly more costly, with billion-dollar events increasing more than five-fold between 2005–2024 compared to 1985–2004. While the overall frequency of severe and tornadic thunderstorms has not changed significantly since 1979, tornado activity is concentrating into more frequent and extreme outbreaks, and 'Tornado Alley' has shifted eastward. Projections suggest a 5-20% increase in conditions favorable to severe thunderstorms per 1.8°F of warming, with one study projecting a 6.6% increase in supercell frequency by the end of the century.

Effective emergency management prevented larger catastrophe after climate change-fueled heavy rains in central Mississippi river valley
An event attribution study found that human-induced climate change increased the likelihood of the April 2025 extreme rainfall in the Central Mississippi river valley by approximately 40% and its intensity by 9%, though observational data suggests these increases could be as high as a factor of 2 to 5 in likelihood and 13-26% in intensity. The event caused at least 24 fatalities and estimated economic damages between $80 and $90 billion, with significant agricultural losses in Arkansas. The study highlights that while climate change amplified the event, effective early warnings from the US National Weather Service prevented a larger catastrophe, despite current staffing shortages in NWS field offices.

DELIVERING AFFORDABILITY
Battery electric heavy-duty vehicles (HDVs) are projected to become the most cost-effective freight transport option in most U.S. states by 2030. While current U.S. purchase prices are anomalously high compared to global trends, falling battery costs and operational savings are driving a clear TCO advantage over diesel and hydrogen fuel cell trucks. The report emphasizes that state-level policy leadership—including price transparency, resale value support, and infrastructure credits like California's LCFS—is critical to unlocking these economic benefits.

Beyond the Smokestack
The document evaluates three industry-proposed methods for reducing carbon emissions from gas plants: hydrogen cofiring, carbon capture and storage (CCS), and biomethane. It concludes that these approaches often fail to achieve targeted emissions reductions when full life cycle impacts—such as upstream methane leakage, energy penalties, and production emissions—are considered. Furthermore, the brief argues that these technologies perpetuate environmental and social inequities by maintaining the operation of gas plants. In contrast, the report finds that transitioning to renewable energy sources like wind and solar provides superior reductions in carbon, air, and water pollution while offering lower costs and fewer land-use impacts.
