The patterns in a climograph describe not just a location's climate but also provide evidence for that climate's relative geographical location. For example, a climograph with a narrow range in temperature over the year might represent a location close to the equator, or alternatively a location adjacent to a large body of water exerting a ...
The key conclusions of Working Group I [11] were: . An increasing body of observations gives a collective picture of a warming world and other changes in the climate system (The global average surface temperature has increased over the 20th century by about 0.6 °C; Temperatures have risen during the past four decades in the lowest 8 kilometres of the atmosphere; Snow cover and ice extent have ...
Publicity over the concerns of scientists about the implications of global warming led to increasing public and political interest, and the Reagan administration, concerned in part about the political impact of scientific findings, successfully lobbied for the 1988 formation of the Intergovernmental Panel on Climate Change to produce reports subject to detailed approval by government delegates ...
A climate change scenario is a hypothetical future based on a "set of key driving forces". [ 1 ] : 1812 Scenarios explore the long-term effectiveness of mitigation and adaptation . [ 2 ] Scenarios help to understand what the future may hold.
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.
The cited estimates of 3.0 °C implies a climate sensitivity to carbon dioxide changes at the low end of the range proposed by the Intergovernmental Panel on Climate Change. [1] However, CLIMAP also suggested that some of the tropics and in particular much of the Pacific Ocean were warmer than they are today.
Climate change increased temperature, reduced the amount of precipitation, decreased snowpack and increased the ability of air to soak humidity, helping to create arid conditions. As of 2021 the drought was the most severe in the last 500 years. [65] As of 30 June 2021 61% of continental USA were in drought conditions.
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.
