To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same impact on the atmosphere and climate as simultaneously preventing an equal amount of carbon dioxide from being emitted.
This is the press release, in Adobe PDF format, announcing the publication of the 700 page IPCC paper, Global Warming of 1.5 °C
The first Special Report, on Global Warming of 1.5 °C was considered by the Panel on 1 - 5 October 2018 in Incheon, Republic of Korea. This is the full public report available online, organized by five chapters, plus glossary.
This Draft Environmental Impact Statement (Draft EIS) analyzes the environmental impacts of fuel
economy standards and reasonable alternative standards for model years 2021 to 2026 for passenger cars
and light trucks. NHTSA has proposed these new or amended Corporate Average Fuel Economy (CAFE)
standards under the Energy Policy and Conservation Act of 1975, as amended by the Energy
Independence and Security Act of 2007. Environmental impacts analyzed in this Draft EIS include those
related to fuel and energy use, air quality, and climate change.
The United States Global Change Research Program (USGCRP) is moving toward a sustained assessment process that allows for more fluid and consistent integration of scientific knowledge into the mandated quadrennial National Climate Assessment. As part of this process, the USGCRP is developing the Climate Science Special Report (CSSR), a technical report that details the current state of science relating to climate change and its physical impacts. The CSSR is intended to focus on climate change in the United States and to inform future USGCRP products, including the Fourth National Climate Assessment
This report is an authoritative assessment of the science of climate change, with a focus on the United States. It represents the first of two volumes of the Fourth National Climate Assessment, mandated by the Global Change Research Act of 1990.
This report addresses the following topics: Observed changes and their
causes; Future climate change, risks and impacts; Future pathways for adaptation, mitigation and sustainable development;
Adaptation and mitigation. Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse
gases are the highest in history. Recent climate changes have had widespread impacts
on human and natural systems. Warming of the climate system is unequivocal, and since the 1950s, many of the observed
changes are unprecedented over decades to millennia. The atmosphere and ocean have
warmed, the amounts of snow and ice have diminished, and sea level has risen.
