Metronome in November 2020, after the original clock was replaced with the 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.
10 January: a summary from the Copernicus Climate Change Service stated that 2024 was the warmest year since records began in 1850, with an average global surface temperature reaching 1.6 °C above pre-industrial levels, surpassing for the first time the 1.5 °C warming target set by the Paris Agreement.
The report's 200-plus authors looked at five warming scenarios and concluded that all will see the world exceed the 1.5-degree threshold set out by the 2015 Paris climate in the 2030s — sooner ...
Scientific consensus on causation: Academic studies of scientific agreement on human-caused global warming among climate experts (2010–2015) reflect that the level of consensus correlates with expertise in climate science. [437] A 2019 study found scientific consensus to be at 100%, [438] and a 2021 study concluded that consensus exceeded 99% ...
If all countries achieve their current Paris Agreement pledges, average warming by 2100 will go far beyond the target of the Paris Agreement to keep warming "well below 2°C". Climate change mitigation scenarios are possible futures in which global warming is reduced by deliberate actions, such as a comprehensive switch to energy sources other ...
In 2003, as lobbying over the 1997 Kyoto Protocol intensified, efforts by the Bush administration to remove climate reconstructions from the first Environmental Protection Agency and Jim Inhofe's Senate speech claiming that man-made global warming is a hoax both drew on the Soon and Baliunas controversy.

RCP 2.6 is a "very stringent" pathway. [6] According to the IPCC, RCP 2.6 requires that carbon dioxide (CO 2) emissions start declining by 2020 and go to zero by 2100.It also requires that methane emissions (CH 4) go to approximately half the CH 4 levels of 2020, and that sulphur dioxide (SO2) emissions decline to approximately 10% of those of 1980–1990.
