The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus, where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times." This consensus is supported by around 200 scientific organizations worldwide, The dominant role in this climate change has been played by the direct emissions of carbon dioxide from the burning of fossil fuels. Indirect CO2 emissions from land use change, and the emissions of methane, nitrous oxide and other greenhouse gases play major supporting roles.
Stephen Henry Schneider was Professor of Environmental Biology and Global Change at Stanford University, a Co-Director at the Center for Environment Science and Policy of the Freeman Spogli Institute for International Studies and a Senior Fellow in the Stanford Woods Institute for the Environment. Schneider served as a consultant to federal agencies and White House staff in the Richard Nixon, Jimmy Carter, Ronald Reagan, George H. W. Bush, Bill Clinton, George W. Bush and Barack Obama administrations.
This glossary of climate change is a list of definitions of terms and concepts relevant to climate change, global warming, and related topics.
James Edward Hansen is an American adjunct professor directing the Program on Climate Science, Awareness and Solutions of the Earth Institute at Columbia University. He is best known for his research in climatology, his 1988 Congressional testimony on climate change that helped raise broad awareness of global warming, and his advocacy of action to avoid dangerous climate change. In recent years, he has become a climate activist to mitigate the effects of global warming, on a few occasions leading to his arrest.
A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal, oil, or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.
Roger Randall Dougan Revelle was a scientist and scholar who was instrumental in the formative years of the University of California, San Diego and was among the early scientists to study anthropogenic global warming, as well as the movement of Earth's tectonic plates. UC San Diego's first college is named Revelle College in his honor.
Chemically, black carbon (BC) is a component of fine particulate matter. Black carbon consists of pure carbon in several linked forms. It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is one of the main types of particle in both anthropogenic and naturally occurring soot. Black carbon causes human morbidity and premature mortality. Because of these human health impacts, many countries have worked to reduce their emissions, making it an easy pollutant to abate in anthropogenic sources.
Are We Changing Planet Earth? and Can We Save Planet Earth? are two programmes that form a documentary about global warming, presented by David Attenborough. They were first broadcast in the United Kingdom on 24 May and 1 June 2006 respectively.
The Virgin Earth Challenge was a competition offering a $25 million prize for whoever could demonstrate a commercially viable design which results in the permanent removal of greenhouse gases out of the Earth's atmosphere to contribute materially in global warming avoidance. The prize was conceived by Richard Branson, and was announced in London on 9 February 2007 by Branson and former US Vice President Al Gore.
The Weather Makers: The History and Future Impact of Climate Change is a 2005 book by Australian scientist Tim Flannery. It discusses climate change, its scientific basis and effects, and potential solutions.
References to climate change in popular culture have existed since the late 20th century and increased in the 21st century. Climate change, its impacts, and related human-environment interactions have been featured in nonfiction books and documentaries, but also literature, film, music, television shows and video games.
In Earth's atmosphere, carbon dioxide is a trace gas that plays an integral part in the greenhouse effect, carbon cycle, photosynthesis and oceanic carbon cycle. It is one of several greenhouse gases in the atmosphere of Earth. The current global average concentration of carbon dioxide in the atmosphere is 421 ppm (0.04%) as of May 2022. This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. The increase is due to human activity.

Greenhouse gases (GHGs) are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. What distinguishes them from other gases is that they absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect. The Earth is warmed by sunlight, causing its surface to radiate heat, which is then mostly absorbed by greenhouse gases. Without greenhouse gases in the atmosphere, the average temperature of Earth's surface would be about −18 °C (0 °F), rather than the present average of 15 °C (59 °F).
The Cornwall Alliance for the Stewardship of Creation is a conservative Christian public policy group that claims that a free-market approach to care for the environment is sufficient, and is critical of much of the current environmental movement. The Alliance is "engaged in a wide range of antienvironmental activities" and denies man-made global warming.
The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy balance and climate. The existence of the greenhouse effect, while not named as such, was proposed as early as 1824 by Joseph Fourier. The argument and the evidence were further strengthened by Claude Pouillet in 1827 and 1838. In 1856 Eunice Newton Foote demonstrated that the warming effect of the sun is greater for air with water vapour than for dry air, and the effect is even greater with carbon dioxide.
350.org is an international environmental organization addressing the climate crisis. Its stated goal is to end the use of fossil fuels and transition to renewable energy by building a global, grassroots movement.
The Weather of the Future: Heat Waves, Extreme Storms, and Other Scenes From a Climate-Changed Planet (ISBN 978-0-06-172688-0) is a 2010 book by climatologist Heidi Cullen. Cullen takes as her starting point the "clear and present dangers" posed by the greenhouse gases which result from the burning fossil fuels. She offers a vision of what life might be like in a warmer world. Cullen predicts "more frequent and more violent storms, more hot spells, cold spells, droughts, famines and huge waves of desperate refugees".
Requiem for a Species: Why We Resist the Truth about Climate Change is a 2010 non-fiction book by Australian academic Clive Hamilton which explores climate change denial and its implications. It argues that climate change will bring about large-scale, harmful consequences for habitability for life on Earth including humans, which it is too late to prevent. Hamilton explores why politicians, corporations and the public deny or refuse to act on this reality. He invokes a variety of explanations, including wishful thinking, ideology, consumer culture and active lobbying by the fossil fuel industry. The book builds on the author's fifteen-year prior history of writing about these subjects, with previous books including Growth Fetish and Scorcher: The Dirty Politics of Climate Change.
This article documents events, research findings, scientific and technological advances, and human actions to measure, predict, mitigate, and adapt to the effects of global warming and climate change—during the year 2022.
