Global Warming FAQ
The document identifies human activity—specifically the burning of fossil fuels and tropical deforestation—as the primary cause of global warming. It explains that carbon dioxide (CO2) is the most significant driver of climate change due to its high radiative forcing and abundance, outweighing other heat-trapping gases and natural climate drivers like solar intensity. The text clarifies that the ozone hole is not a cause of global warming, though both result from human atmospheric alterations. Observed impacts include a 1°C increase in global average surface temperature since the pre-industrial age, rising sea levels, and ecological shifts such as thawing permafrost and altered species ranges.

How Hydroelectric Energy Works
Hydroelectric power is a major source of emissions-free electricity that utilizes the hydrologic cycle to generate power via turbines. While it offers a flexible, renewable alternative to fossil fuels, it can cause significant ecological damage, such as blocking fish migration and emitting methane from reservoirs. The document details various turbine types, the role of pumped storage, and the potential for low-impact certification and new development in the U.S. and developing nations.

Applied Hope
The document presents a vision of "applied hope," which Lovins defines as a deliberate choice to act on the conviction that practical, scalable solutions can improve the world. He argues against passive optimism and pervasive dread, advocating instead for "integrative design" and "advanced resource efficiency" to phase out fossil fuels and nuclear energy. Lovins envisions a future where carbon emissions decline profitably, biodiversity recovers, and global stability is achieved by treating the world's problems as interconnected systems rather than isolated issues.

THE ROLE OF CARBON CAPTURE AND STORAGE TECHNOLOGY IN ATTAINING GLOBAL CLIMATE STABILITY TARGETS: A LITERATURE REVIEW
The report reviews multiple global and regional studies to determine the necessity of carbon capture and storage (CCS) for climate mitigation. It concludes that most experts view CCS as a key technology for reducing greenhouse gas emissions to stabilization levels by 2030-2050, often serving as a cost-effective alternative to massive nuclear expansion or extremely ambitious energy efficiency and renewable targets.

Imagine a World...
In a 2007 speech, Amory B. Lovins advocates for 'linked, multiplying solutions' to global problems, envisioning a future where energy efficiency, distributed renewables, and advanced biofuels replace oil, coal, and nuclear power. He describes a world where carbon emissions decline profitably, resource waste is eliminated through biomimicry and integrative engineering, and global stability is achieved through the removal of energy-driven conflicts and the adoption of a resource-efficient human population.

Wind Power in New England
The document outlines the environmental and economic benefits of wind energy in New England, noting that over 60 percent of the region's electricity was generated from fossil fuels in 2005. It explains how wind power integrates into the grid via ISO New England to displace more expensive and polluting plants, particularly oil-fired plants during winter peaks. The text highlights that 18 proposed wind projects with a total capacity of 1,890 MW could avoid millions of tons of pollution annually, including over 3 million tons of CO2. It also discusses the importance of siting for efficiency and the role of policy mechanisms like cap-and-trade and renewable portfolio standards in accelerating the transition.

Una Respuesta de la Sociedad Civil al Marco de Inversión del Banco Mundial para Energía Limpia y Desarrollo
The document argues that the World Bank's energy investment framework is a continuation of 'more of the same', failing to transition from fossil fuels to renewables. It highlights a contradiction where the Bank acts as a major carbon trader while continuing to fund projects that emit massive amounts of greenhouse gases. The report criticizes the Bank's promotion of 'clean coal', nuclear energy, and large dams, asserting these technologies cause significant environmental and social harm. It calls for a redirection of public finance from the North to the South toward decentralized renewable energy and energy efficiency to meet the needs of the world's poor.

les mythes du gazoduc de l'afrique de l'ouest
The report argues that the West African Gas Pipeline (WAGP), a 681 km project involving Nigeria, Benin, Togo, and Ghana, fails to deliver its promised benefits. It contends that the project does not promote genuine regional integration, may increase energy costs for Ghana, and is unlikely to significantly reduce gas flaring in Nigeria. The document highlights concerns over the project's legal structure in Bermuda, the lack of environmental impact studies for the Escravos pipeline, and the continued reliance on fossil fuels.

the tyranny of free trade wasted natural wealth and lost livelihoods
The report examines how trade liberalization, specifically through the WTO's Doha Round and NAMA negotiations, facilitates the privatization of natural resources and harms marginalized populations. It provides case studies on the depletion of fisheries in the Philippines and Seychelles, deforestation in Indonesia and Central America, and the impact of industrial pig farming and soy expansion in Denmark and Argentina. The document advocates for food and energy sovereignty and the recognition of water as a human right over a tradable commodity.

Resource Wealth and the Risk of Civil War Onset: Results from a New Data Set of Natural Resource Rents, 1970–1999
The study finds that energy wealth, but not mineral wealth, increases the risk of civil war onset, provided a lower threshold of 25 annual battle deaths is used. The results provide evidence against the 'looting rebels' model, which predicts a non-linear relationship where very high resource wealth eventually deters rebellion, and instead tentatively support state capacity models suggesting that fossil fuel dependence weakens state institutions.

Michael Crichton's State of Fear
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
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.

Knowledge and Insight Required to Act under Uncertainty Focusing on Robust Findings
The document emphasizes that scientific uncertainties should not justify delaying preventive actions against climate change. It highlights robust facts, such as the role of greenhouse gases and the delaying effect of aerosols and ocean inertia, to argue for a precautionary approach. The author notes that current efforts, including the Kyoto Protocol, are insufficient to stabilize atmospheric concentrations, and calls for industrial countries to lead emissions reductions to ensure global equity and sustainable development.
