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 change education (CCE) is education that aims to address and develop effective responses to climate change. It helps learners understand the causes and consequences of climate change, prepares them to live with the impacts of climate change and empowers learners to take appropriate actions to adopt more sustainable lifestyles.

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 substances ...
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 climate change ...
A short description of the RCPs is as follows: RCP 1.9 is a pathway that limits global warming to below 1.5 °C, the aspirational goal of the Paris Agreement. [4] RCP 2.6 is a very stringent pathway. [4] RCP 3.4 represents an intermediate pathway between the very stringent RCP2.6 and less stringent mitigation efforts associated with RCP4.5. [5]
In a troubling milestone, June marked Earth's 12th consecutive month of global warming at or above 1.5 degrees Celsius — the internationally accepted threshold for avoiding the worst effects of ...
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 ...
Per capita CO2 emissions in Canada, 1790-2022. Climate change is the result of greenhouse gas emissions, which are produced by human activity. Canada was the world's 7th largest greenhouse gas emitter in terms of GHG Inventory data, as of 2021. [ 4] In 2020, Canada emitted a total of 678 million tons of carbon dioxide equivalent (Mt CO 2 eq ...
