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 ...
Climate fiction (sometimes shortened to cli-fi) is literature that deals with climate change. [ 1] Generally speculative in nature but inspired by climate science, works of climate fiction may take place in the world as we know it, in the near future, or in fictional worlds experiencing climate change. The genre frequently includes science ...
The current scientific consensus regarding causes and mechanisms of climate change, its effects and what should be done about it ( climate action) is that: It is "unequivocal" and "incontrovertible" that the greenhouse gas emissions from human activities have caused warming on land, in oceans and in the troposphere.
This is close to the observed overall warming during that time of 0.9 °C to 1.2 °C. Temperature changes during that time were likely only ±0.1 °C due to natural forcings and ±0.2 °C due to variability in the climate. [31]: 3, 443 Global anthropogenic greenhouse gas emissions in 2019 were equivalent to 59 billion tonnes of CO 2.
In common usage, climate change describes global warming —the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate.
Definition. The global warming potential (GWP) is defined as an "index measuring the radiative forcing following an emission of a unit mass of a given substance, accumulated over a chosen time horizon, relative to that of the reference substance, carbon dioxide (CO 2 ). The GWP thus represents the combined effect of the differing times these ...
Timothy Francis Ball (November 5, 1938 – September 24, 2022) was a British-born Canadian public speaker and writer who was a professor in the Department of Geography at the University of Winnipeg from 1971 until his retirement in 1996. Subsequently Ball became active in promoting rejection of the scientific consensus on global warming, giving ...
Climate sensitivity is a key measure in climate science and describes how much Earth's surface will warm for a doubling in the atmospheric carbon dioxide (CO 2) concentration. [ 1][ 2] Its formal definition is: "The change in the surface temperature in response to a change in the atmospheric carbon dioxide (CO 2) concentration or other ...
