A fossil fuel is a hydrocarbon-containing material such as coal, oil, and natural gas, formed naturally in the Earth's crust from the remains of dead plants and animals that is extracted and burned as a fuel. Fossil fuels may be burned to provide heat for use directly, to power engines, or to generate electricity. Some fossil fuels are refined into derivatives such as kerosene, gasoline and propane before burning. The origin of fossil fuels is the anaerobic decomposition of buried dead organisms, containing organic molecules created by photosynthesis. The conversion from these materials to high-carbon fossil fuels typically require a geological process of millions of years.
Climate change mitigation is action to limit climate change. This action either reduces emissions of greenhouse gases or removes those gases from the atmosphere. The recent rise in global temperature is mostly due to emissions from burning fossil fuels such as coal, oil, and natural gas. There are various ways that mitigation can reduce emissions. These are transitioning to sustainable energy sources, conserving energy, and increasing efficiency. It is possible to remove carbon dioxide from the atmosphere. This can be done by enlarging forests, restoring wetlands and using other natural and technical processes. The name for these processes is carbon sequestration. Governments and companies have pledged to reduce emissions to prevent dangerous climate change. These pledges are in line with international negotiations to limit warming.
The politics of climate change results from different perspectives on how to respond to climate change. Global warming is driven largely by the emissions of greenhouse gases due to human economic activity, especially the burning of fossil fuels, certain industries like cement and steel production, and land use for agriculture and forestry. Since the Industrial Revolution, fossil fuels have provided the main source of energy for economic and technological development. The centrality of fossil fuels and other carbon-intensive industries has resulted in much resistance to climate friendly policy, despite widespread scientific consensus that such policy is necessary.
Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide, from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the United States. The United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies. Emissions from human activities have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before. Total cumulative emissions from 1870 to 2017 were 425±20 GtC from fossil fuels and industry, and 180±60 GtC from land use change. Land-use change, such as deforestation, caused about 31% of cumulative emissions over 1870–2017, coal 32%, oil 25%, and gas 10%.
Climate justice describes an approach to climate action that focuses on the unequal impacts of climate change on marginalized or otherwise vulnerable populations. Climate justice is a type of environmental justice and focuses on the equitable distribution of the burdens of climate change and the efforts to mitigate them. It has been described as encompassing "a set of rights and obligations, which corporations, individuals and governments have towards those vulnerable people who will be in a way significantly disproportionately affected by climate change."
Michael D. Shellenberger is an American author and journalist who writes about politics, the environment, climate change, and nuclear power. He is a co-founder of the Breakthrough Institute and the California Peace Coalition. Shellenberger founded the pro-nuclear non-profit Environmental Progress in 2016.
The environment of the United States comprises diverse biotas, climates, and geologies. This diversity leads to a number of different distinct regions and geographies in which human communities live. This includes a rich variety of species of animals, fungi, plants and other organisms.
Environmental issues in the United States include climate change, energy, species conservation, invasive species, deforestation, mining, nuclear accidents, pesticides, pollution, waste and over-population. Despite taking hundreds of measures, the rate of environmental issues is increasing rapidly instead of reducing. The United States is among the most significant emitters of greenhouse gasses in the world. In terms of both total and per capita emissions, it is among the largest contributors. The climate policy of the United States has a major influence on the world.
Climate crisis is a term describing global warming and climate change, and their impacts. This term and the term climate emergency have been used to describe the threat of global warming to humanity and the planet, and to urge aggressive climate change mitigation. In the scientific journal BioScience, a January 2020 article, endorsed by over 11,000 scientists worldwide, stated that "the climate crisis has arrived" and that an "immense increase of scale in endeavors to conserve our biosphere is needed to avoid untold suffering due to the climate crisis."
Climate change has led to the United States warming by 2.6 °F since 1970. The climate of the United States is shifting in ways that are widespread and varied between regions. From 2010 to 2019, the United States experienced its hottest decade on record. Extreme weather events, invasive species, floods and droughts are increasing. Climate change's impacts on tropical cyclones and sea level rise also affects regions of the country.
Philip David Radford is an American activist who served as the executive director of Greenpeace USA. He was the founder and President of Progressive Power Lab, an organization that incubates companies and non-profits that build capacity for progressive organizations, including a donor advisory organization Champion.us, the Progressive Multiplier Fund and Membership Drive. Radford is a co-founder of the Democracy Initiative, was founder and executive director of Power Shift, and is a board member of the Mertz Gilmore Foundation. He has a background in grassroots organizing, corporate social responsibility, climate change, and clean energy. He currently serves as the Chief Strategy officer at the Sierra Club.
Public opinion on climate change is related to a broad set of variables, including the effects of sociodemographic, political, cultural, economic, and environmental factors as well as media coverage and interaction with different news and social media. International public opinion on climate change shows a majority viewing the crisis as an emergency.
Climate finance consists of funding processes for investments related to climate change mitigation and adaptation. The term has been used in a narrower sense to refer to transfers of public resources from developed to developing countries, in light of their UN Climate Convention obligations to provide "new and additional financial resources". In a wider sense, the term refers to all financial flows relating to climate change mitigation and adaptation.

Founded in 2007 by Michael Shellenberger and Ted Nordhaus, The institute is aligned with ecomodernist philosophy. The Institute advocates for an embrace of modernization and technological development in order to address environmental challenges. Proposing urbanization, agricultural intensification, nuclear power, aquaculture, and desalination as processes with a potential to reduce human demands on the environment, allowing more room for non-human species.
The climate movement is a global social movement focused on pressuring governments and industry to take action addressing the causes and impacts of climate change. Environmental non-profit organizations have engaged in significant climate activism since the late 1980s and early 1990s, as they sought to influence the United Nations Framework Convention on Climate Change (UNFCCC). Climate activism has become increasingly prominent over time, gaining significant momentum during the 2009 Copenhagen Summit and particularly following the signing of the Paris Agreement in 2016.
