The Group 4: Experimental sciences subjects of the International Baccalaureate Diploma Programme comprise the main scientific emphasis of this internationally recognized high school programme. They consist of seven courses, five of which are offered at both the Standard Level (SL) and Higher Level (HL): Chemistry, Biology, Physics, Design ...
Idealized greenhouse model. A schematic representation of a planet's radiation balance with its parent star and the rest of space. Thermal radiation absorbed and emitted by the idealized atmosphere can raise the equilibrium surface temperature. The temperatures of a planet's surface and atmosphere are governed by a delicate balancing of their ...
Climate Clock. The Climate Clock is a graphic to demonstrate how quickly the planet is approaching 1.5 °C of global warming, given current emissions trends. [ 1] It also shows the amount of CO 2 already emitted, and the global warming to date. The Climate Clock was launched in 2015 to provide a measuring stick against which viewers can track ...
Drawdown (climate) Climate drawdown refers to the future point in time when levels of greenhouse gas concentrations in the atmosphere stop climbing and start to steadily decline. [ 1] Drawdown is a milestone in reversing climate change and eventually reducing global average temperatures. [ 2] Project Drawdown refers to a nonprofit organization ...
Other approaches to mitigating climate change have a higher level of risk. Scenarios that limit global warming to 1.5 °C typically project the large-scale use of carbon dioxide removal methods over the 21st century. [292] There are concerns, though, about over-reliance on these technologies, and environmental impacts. [293]
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 ...
Climate change feedbacks are natural processes which impact how much global temperatures will increase for a given amount of greenhouse gas emissions. Positive feedbacks amplify global warming while negative feedbacks diminish it. [ 2]: 2233 Feedbacks influence both the amount of greenhouse gases in the atmosphere and the amount of temperature ...
Climate change scenarios can be thought of as stories of possible futures. They allow the description of factors that are difficult to quantify, such as governance, social structures, and institutions. There is considerable variety among scenarios, ranging from variants of sustainable development, to the collapse of social, economic, and ...
