Biocombustibles para principiantes
The document explains that biofuels are intended to reduce, rather than replace, fossil fuel use, particularly in hard-to-electrify sectors like aviation and shipping. It distinguishes between three generations of biofuels: first-generation (food-based), second-generation (waste-based), and third-generation (algae-based). While they can reduce emissions if produced sustainably, first-generation fuels can increase deforestation and biodiversity loss. The guide highlights regional production patterns in the Americas, noting Brazil's leadership in sugarcane ethanol and Colombia's role in palm oil biodiesel.

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.

Community Benefits Snapshot: North Plains Connector Transmission Line Community Engagement and Benefits
The North Plains Connector (NPC) is a $3.2 billion, 420-mile high-voltage direct current transmission project designed to connect the western and eastern electric grids. The developer, North Plains Connector LLC, has adopted a "landowner-first approach," prioritizing voluntary agreements over eminent domain and modifying the route by adding 50 miles to accommodate local siting requests. Community benefits include $3.9 million in grants distributed via local foundations, over $62 million in federal TSED grants secured for local infrastructure, and the creation of approximately 800 construction jobs. The project also facilitates expanded wind energy exports for the Standing Rock Sioux. While this high-upfront-investment model has reduced local opposition, the document notes it requires "patient capital" and its long-term financial efficiency compared to traditional development remains unproven.

Monthly Attribution Overview February 2025
In February 2025, U.S. temperature anomalies were split, with 92 cities warmer and 99 cooler than the 1991-2020 normal. Despite an average anomaly of -0.3°F and significant cold in the Northern Rockies and Plains, no city set a low temperature record for the month. Conversely, Phoenix, Arizona, recorded its hottest February on record. Analysis using the Climate Shift Index (CSI) indicates that temperatures in many cities remained warmer than they would have been without climate change, as more cities experienced days with positive than negative CSI values. Long-term trends show that 189 out of 191 analyzed stations have warmed since 1970, with Juneau, Alaska, being the fastest-warming station for February.

FEDERAL CLEAN ENERGY TAX CREDITS MAKE ENERGY MORE AFFORDABLE – A META-ANALYSIS
The document argues that repealing federal technology-neutral electricity tax credits (§45Y and §48E) would significantly increase household energy bills across the United States. Drawing on analyses from multiple research groups, it estimates that national annual household energy bills would rise by $40–$60 in 2030, $56–$150 in 2035, and $140–$220 by 2040. The report highlights that these credits lower costs by reducing investment expenses for wind, solar, battery, nuclear, and geothermal projects, savings which utilities are regulated to pass on to consumers. Repeal would likely lead to substantial price hikes in specific states, with some households facing increases over $500 annually.

Wetlands in Peril
The Union of Concerned Scientists reports that industrial agriculture is the leading cause of wetland loss over the last 250 years, which increases flood risks and releases stored carbon. In the Upper Midwest, 30 million acres of wetlands provide approximately $23 billion in annual residential flood mitigation benefits, with long-term value estimated between $323 billion and $754 billion. The document urges the US government to use the upcoming farm bill to increase funding for USDA conservation programs, such as the Conservation Reserve Program and Wetland Reserve Easements, to protect these ecosystems.

Wetlands in Peril
Industrial agriculture is a primary driver of wetland loss in the US Upper Midwest, where 30 million acres of wetlands provide critical flood mitigation and carbon sequestration. The report estimates that these wetlands provide nearly $23 billion in annual residential flood mitigation benefits, with long-term value between $323 billion and $754 billion. Recent legal shifts, specifically the 2023 Supreme Court ruling in Sackett v. EPA, have reduced federal protections under the Clean Water Act, leaving many wetlands vulnerable. The author argues that the next farm bill should expand the Conservation Reserve Program (CRP) cap, increase funding for the Conservation Stewardship Program (CSP) and Environmental Quality Incentives Program (EQIP), and link crop insurance to conservation practices to mitigate flood risk and support environmental justice for marginalized communities.

DASD Caroline Baxter on Integrating Climate Change into Professional Military Education
DASD Caroline Baxter describes the U.S. Department of Defense's (DoD) efforts to integrate climate literacy into professional military education (PME). She argues that climate change acts as a "threat multiplier" affecting installations, mission demand, and budgets. The DoD's approach focuses on making climate information mission-relevant, integrating it into existing curricula to avoid task saturation, and emphasizing readiness and lethality over political terminology. Key initiatives include the Climate Literacy Sub-Working Group, a new outcomes-based PME instruction, and a dedicated online portal for authoritative climate information.

Wettest Seasons in U.S. Regions
Climate Central analyzed precipitation data from 1969-70 to 2022-23 for the contiguous U.S., finding that while some regions have balanced seasonal rainfall, others rely heavily on a single season. Specifically, the West and Northwest are dominated by winter precipitation, while the Plains and Upper Midwest rely on summer rainfall. Climate change is altering these patterns, with a general increase in precipitation east of the Rockies and a decrease to the west. Warmer temperatures are increasing atmospheric moisture—approximately 10% more since 1970—which enhances extremes such as heavy downpours and intensifying droughts.

No Grain Left Behind
The study found that actual harvest losses for corn (4.7%) and soybeans (4.5%) significantly exceed industry goals (1% and 3% respectively). These losses are primarily driven by combine settings and operator error, with smaller farms using less sophisticated equipment experiencing the highest losses. The report argues that reducing these losses could significantly decrease the pressure to convert natural prairies to cropland in the Northern Great Plains.

Climate Central Temperature Attribution System Methods
The Climate Central Temperature Attribution System (CC-TAS) Version 1.0 operationalizes a multi-method framework to attribute temperature events to anthropogenic climate change. It utilizes two empirical methods (median-scaling and quantile-scaling) and a model-based method using CMIP6 simulations. To improve upon previous frameworks, CC-TAS incorporates high-resolution CFS reanalysis temperatures, ERA5 reanalysis for scale factors, and skew-normal parameterized distributions. The system introduces the 'occurrence ratio' (OR) as a primary metric to assess both warm and cold events, which is then converted into a conservative categorical 'Climate Shift Index' (CSI) for public mapping, primarily focusing on the contiguous United States.

The Shaky Economics of Gas-fired Power Generation
The report finds that gas-fired power plants in MISO and SPP frequently operate at a loss, costing ratepayers an estimated $117 million in 2019. This uneconomic generation is most prevalent in steam turbines and gas turbines, often driven by practices like self-scheduling and self-commitment. The authors argue that these inefficiencies, combined with rising fuel costs and the growth of renewables, make gas-fired power an increasingly risky and expensive investment compared to clean energy portfolios.

PLOW PRINT 2022 REPORT
In 2020, approximately 1.8 million acres of grasslands were converted to cropland across the Great Plains, with 385,000 acres lost in the Northern Great Plains. For the first time since the report's inception, wheat has replaced corn as the primary crop driving this loss across the entire region. While the 2020 conversion rate was lower than the five-year average, nearly 10 million acres have been plowed since 2016. The report highlights policy mechanisms for conservation, including the North American Grasslands Conservation Act and the 2023 Farm Bill, and notes the threat of woody-encroachment as a significant, though separate, driver of grassland loss.

FIRE WEATHER
Climate Central's analysis of weather station data from 225 locations across 17 U.S. states reveals a significant increase in fire weather days since the 1970s, driven primarily by warming and decreasing relative humidity. The report highlights that interior regions have seen higher increases than coastal areas, with some parts of New Mexico experiencing two additional months of fire weather compared to nearly 50 years ago. Beyond increasing wildfire risk, these conditions have led utilities like PG&E to implement public safety power shutoffs (PSPSs) to prevent equipment-related ignitions, resulting in significant economic impacts and health risks. The document argues that while land management and localized grids can mitigate risk, long-term stabilization requires reducing carbon pollution to net zero by 2050.
