The document provides a detailed breakdown of survey responses from 279 federal climate scientists across seven U.S. agencies. It assesses perceptions of scientific integrity, the quality of federal climate research, and specific instances of political interference. Key data points include a majority of respondents viewing the environment for federal climate science as worse than it was 5 or 10 years ago, and various reported experiences of pressure to alter scientific findings or terminology.

The Union of Concerned Scientists (UCS) surveyed over 1,600 federal climate scientists in 2006 to investigate the state of climate research at U.S. federal agencies. The survey targeted agencies including NASA, NOAA, EPA, USGS, USDA, DOE, and DOD, using the National Center for Atmospheric Research (NCAR) as a non-federal control group to measure political interference. Out of the surveys mailed, 308 were completed (a 19 percent response rate), consisting of 279 from federal agencies and 29 from NCAR. The respondent pool was highly qualified, with 80 percent holding a Ph.D. and over half having more than 10 years of experience at their current agencies.

The report evaluates U.S. school bus emissions, finding that older diesel buses release significantly more soot than modern alternatives, posing health risks to children. It grades states on soot emissions, cleanup programs, and smog-forming pollution, noting wide performance gaps. The authors recommend a strategy of 'the five Rs'—retrofitting, refueling, replacement, repair, and reduced idling—and call for strengthened federal standards and increased funding to modernize fleets.

The report examines the economic framework of the emerging pharmaceutical crop industry, arguing that while proponents claim significant rural benefits, these are largely unsubstantiated projections. It finds that the primary economic gains are likely to accrue to pharmaceutical companies rather than farmers, who will face limited bargaining power and high risks associated with food supply contamination. The document highlights that the industry's success depends on achieving virtually zero risk of commingling pharma crops with food and feed supplies, a requirement that may significantly increase production costs and offset projected savings.

The report identifies six loopholes—three regulatory and three tax/policy-based—that have contributed to a decline in U.S. fleet fuel economy from a 1987 peak of nearly 26 mpg to 24.4 mpg by 2004. These include the misclassification of passenger vehicles as 'non-passenger' to meet lower standards, the total exemption of vehicles over 8,500 lbs GVWR, and inflated credits for dual-fuel vehicles that rarely use alternative fuels. It also highlights tax incentives for luxury SUVs and the exclusion of light trucks from the 'gas guzzler' tax. The authors argue that closing these loopholes could reduce U.S. oil dependence by 1.5 million barrels per day by 2025 and save consumers $33 billion.

The Union of Concerned Scientists addresses several claims from Michael Crichton's State of Fear that cast doubt on global warming. The document explains that regional cooling trends are compatible with global warming due to factors like sulfate aerosols, and that the urban heat island effect is a minor component of temperature trends. It asserts that CO2 is a primary driver of warming, though other factors like volcanic eruptions influence short-term trends. The text highlights the retreat of major ice sheets and the long-term persistence of atmospheric CO2 as urgent reasons to reduce fossil fuel dependence.

Solar water heating (SWH) systems provide a cost-effective way to reduce reliance on fossil fuels for heating water, which accounts for up to 14 percent of average US household energy use. These systems, which range from $2,000 to $5,000 for residential use, can meet 50 to 80 percent of a typical household's hot water needs, and up to 100 percent in climates like Hawaii. The guide details various system types—including flat panel collectors and direct, indirect, and drain-back systems—tailored to different climatic conditions. It also highlights the efficiency of solar pool heating and the role of utility incentives and policy support in increasing adoption.

The document details how NOAA officials, including lab director Dr. David Hofmann, attempted to restrict the use of terms like "climate change" and "Kyoto" in presentations and papers at the Seventh International Carbon Dioxide Conference. Evidence from FOIA requests and interviews suggests that funding agencies stipulated topics be limited to "carbon dioxide measurements and modeling, rather than climate change and climate modeling." Dr. Pieter Tans reported that material concerning climate change, including laboratory website content, required White House pre-approval, and that the conference website was ordered to remove links connecting CO2 increase to climate change. Dr. Tans noted that such restrictions damage the credibility of government scientists and create an atmosphere of intimidation for some researchers.

Diesel-powered transportation sources in the US are responsible for over 60 percent of nitrogen oxides (NOx) and more than 70 percent of fine particulate matter (PM2.5) emissions. The World Health Organization classifies diesel exhaust as carcinogenic, with components like PM2.5 and NOx causing respiratory and cardiovascular illnesses, premature death, and reduced lung function. These health impacts disproportionately affect communities of color and socioeconomically disadvantaged populations. While over 100 models of electric trucks and buses are currently available, the document argues that public policy is necessary to accelerate the market and address the climate crisis and health disparities.

The report details multiple instances where the George W. Bush administration intervened in federal scientific reporting to downplay the human role in global warming. Key examples include the removal of climate sections from EPA reports, the censorship of a USDA brochure on carbon sequestration, and the editing of scientific summaries by a non-scientist former oil industry lobbyist to increase perceived uncertainty. The document asserts that these actions undermined the integrity of federal agencies and contradicted the scientific consensus established by the IPCC and the National Academy of Sciences.

Dr. James Zahn, a former USDA research microbiologist, reported being prohibited on at least 11 occasions from publicizing findings on antibiotic-resistant bacteria in the air near hog operations in Iowa and Missouri. Despite the USDA's stated mission to address human health in swine production, Zahn was barred from presenting his research at 2002 scientific conferences, with supervisors citing the need for discretion on "politically sensitive and controversial issues." This suppression is linked to a February 2002 USDA directive requiring prior approval for research on "sensitive issues," including agricultural practices with negative health and environmental consequences such as global climate change and animal feeding operations.

The Union of Concerned Scientists analyzed two proposals to increase the Texas Renewable Energy Standard (RPS): a 20 percent by 2020 target (TREIA proposal) and a 10,000 MW by 2025 target (TEPC proposal). Using the EIA's National Energy Modeling System, the analysis found that both proposals would lower consumer energy bills, create jobs, and reduce CO2 emissions, with the 20 percent proposal yielding significantly higher benefits. By 2025, the 20 percent standard is projected to save consumers $5.6 billion in total energy bills, create 38,290 new jobs, and reduce annual power plant CO2 emissions by 20 million metric tons.

The Union of Concerned Scientists analyzed two proposals to increase the Texas Renewable Portfolio Standard (RPS). The more aggressive 20 percent by 2020 proposal would result in 17,820 MW of renewable capacity by 2025, creating 38,290 new jobs and saving consumers $5.6 billion in energy bills. The more modest 10,000 MW by 2025 proposal would yield approximately 8 percent renewable energy by 2025, creating 19,950 new jobs and $5.5 billion in consumer savings. Both proposals would diversify the electricity mix by displacing natural gas and coal, reducing CO2 emissions and providing significant capital investment and tax revenues to rural Texas communities.

The report identifies a warming and potentially drier trend for the Great Lakes region, predicting significant temperature increases and shifts in precipitation patterns by the end of the 21st century. These changes are expected to disrupt aquatic ecosystems, reduce forest diversity, and create economic risks for agriculture and shipping. The document advocates for a three-pronged approach: reducing greenhouse gas emissions, minimizing local environmental pressures, and planning for climate adaptation.

The document examines the physical constraints of space operations, arguing that while space is uniquely suited for civilian and reconnaissance missions, it is poorly suited for kinetic ground-attack and boost-phase missile defense due to high costs, reliability issues, and intrinsic vulnerabilities. It details the mechanics of various orbits (LEO, MEO, GEO, Molniya, Tundra), the propellant requirements for maneuvering, and the technical methods for interfering with satellites, including jamming, dazzling, and kinetic energy attacks. The authors conclude that being the first to deploy space-based weapons would not confer a lasting military advantage because space lacks strategic locations and satellites remain inherently vulnerable.

The report ranks the 'Big Six' automakers—Honda, Nissan, Toyota, Ford, DaimlerChrysler, and General Motors—on their environmental performance, focusing on smog-forming and heat-trapping emissions. Honda consistently ranks as the cleanest, while General Motors has fallen to the bottom. The analysis highlights a trend where smog-forming pollution is improving due to regulation, but heat-trapping emissions remain stagnant. It specifically criticizes the use of regulatory loopholes, such as Flex-Fuel Vehicle (FFV) credits, which allow companies to artificially inflate fuel economy figures.

The Union of Concerned Scientists (UCS) and a panel of experts conclude that current U.S. corn and soybean production, storage, and transport systems cannot prevent the contamination of the food and feed supply by pharma crops. The report advocates for a "virtually zero contamination" standard and recommends that the USDA halt outdoor production of these crops until a separate, dedicated system is established. Proposed alternatives include using non-food crops like tobacco, guayule, or jojoba, indoor cultivation, and the implementation of rigorous confinement management systems.

The San Joaquin Valley shares the distinction of having the worst air quality in the United States, driven by a combination of geographic trapping, rapid population growth, and a history of regulatory neglect. The region struggles with chronic ozone and particulate matter (PM) pollution, which disproportionately affects vulnerable populations and damages the agricultural economy. While recent legislation has begun to regulate previously exempt agricultural sources and diesel emissions, the report argues that coordinated action across jurisdictional levels is required to address emissions from sources outside local control, such as heavy-duty trucks and locomotives.

The Union of Concerned Scientists analyzed the potential effects of Colorado's Amendment 37, which would require the state's largest electric companies to increase renewable energy use to 10 percent of sales by 2015. Under the most likely scenario, the report projects that the initiative would result in $236 million in consumer savings on electricity and natural gas bills, the creation of 2,000 new jobs by 2020, and a reduction of 3 million metric tons of annual CO2 emissions by 2025. The analysis highlights that wind resources would drive most of the development, providing significant capital investment and tax revenues for rural communities.

The report analyzes the potential consequences of a terrorist attack at the Indian Point nuclear power plant, arguing that current 10-mile emergency planning zones are inadequate. Using the MACCS2 computer code, the author estimates that a successful attack could result in up to 44,000 near-term deaths and 518,000 long-term cancer deaths within 50 miles, with economic damages reaching $2.1 trillion. The analysis highlights that residents of New York City are at significant risk, particularly children who may require potassium iodide (KI) to prevent thyroid cancer, and suggests that sheltering may be more effective than evacuation for those outside the immediate 10-mile zone.
