Warming stripes — Accepts a single dataset and converts to SVG code portraying Ed Hawkins' warming stripes graphics. User chooses vertical or horizontal stripes; normal or reverse data ordering; or from a variety of geometric shapes (updated 17 May 2023). . . . . Click here to see examples of warming stripes embedded in different shapes.
20210508 Warming stripes - hexagons - global warming.svg 20210507 Warming stripes - octagons - global warming.svg The spreadsheet user can toggle a switch to reverse the order of data, so red is in the center (or left side of first graphic) and blue is at the outside (or right side of first graphic).
Since the upper layers are colder, the amount emitted would be lower, leading to warming of Earth until the reduction in emission is compensated by the rise in temperature. [1] Furthermore, such warming may cause a feedback mechanism due to other changes in Earth's albedo, e.g. due to ice melting.

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. [280] There are concerns, though, about over-reliance on these technologies, and environmental impacts. [281]
Climate models vary in complexity. For example, a simple radiant heat transfer model treats the Earth as a single point and averages outgoing energy. This can be expanded vertically (radiative-convective models) and horizontally. More complex models are the coupled atmosphere–ocean–sea ice global climate models.
With 21% of global methane emissions, cattle are a major driver of global warming. [ 225 ] : 6 When rainforests are cut and the land is converted for grazing, the impact is even higher. In Brazil, producing 1 kg of beef can result in the emission of up to 335 kg CO 2 -eq. [ 226 ] Increasing the milk yield of dairy cows has been shown to reduce ...
For example, the IPCC Special Report on Global Warming of 1.5 °C was a "key scientific input" into the 2018 United Nations Climate Change Conference. [4] Various pathways are considered in the report, describing scenarios for mitigation of global warming. Pathways include for example portfolios for energy supply and carbon dioxide removal.
