Such reconstructions inform processes and act as benchmarks for Earth system models of the global carbon cycle over the recent geologic past (Section 5. Zhou, C.

The season of change. Shine, 2018: Historical Tropospheric and Stratospheric Ozone Radiative Forcing Using the CMIP6 Database. Global models with finer horizontal grids better represent many aspects of the circulation of the atmosphere (Gao et al., 2020; Schiemann et al., 2020) and ocean (Bishop et al., 2016; Storkey et al., 2018), bringing improvements in the simulation of the global hydrological cycle (Roberts et al., 2018). The broader availability of large model ensembles may allow for novel tests of fitness that better account for natural climate variability (Section 1.

0, as it has very similar temperature projections compared to the nominally lower RCP4. The spatial (and temporal) resolution of these grids in both the horizontal and vertical directions determines which processes need to be parameterized or whether they can be explicitly resolved. For example, Frölicher and Paynter (2015) showed that EMICs have a higher simulated realized warming fraction (i. e., the TCR/ECS ratio) than CMIP5 ESMs and speculated that this may bias the temperature response to zero carbon emissions. Köppen, W., 1936: Das geographische System der Klimate. Despite the key role of CMIP6 in this Report (Section 1.

With much more data and better models, we also understand more about how the atmosphere interacts with the ocean, ice, snow, ecosystems and land surfaces of the Earth. Models reproduce observed continental-scale surface temperature patterns and trends over many decades, including the more rapid warming since the mid-20th century and the cooling immediately following large volcanic eruptions.

2 The skills needed in a digital age. Changed Rebooting, respawns players in a Rift instead of the top of the Reboot Van. One limitation of the SSP scenarios used for CMIP6 and in this Report is that they reduce emissions from all the major ozone-depleting substances controlled under the Montreal Protocol (CFCs, halons, and hydrochlorofluorocarbons (HCFCs)) uniformly, rather than representing a fuller range of possible high- and low-emissions futures (UNEP, 2016). Reconstructions of climate data for the past 1, 000 years indicate this warming was unusual and is unlikely to be entirely natural in origin. Lee, L. A., K. Carslaw, K. Pringle, G. Mann, and D. Spracklen, 2011: Emulation of a complex global aerosol model to quantify sensitivity to uncertain parameters. The Coordinated Regional Downscaling Experiment (CORDEX; Gutowski Jr. et al., 2016) is an intercomparison project for regional models and statistical downscaling techniques, coordinating simulations on common domains and under common experimental conditions in a similar way to the CMIP effort. The ERA-20C atmospheric reanalysis (covering 1900–2010; Poli et al., 2016) also assimilates marine wind observations, and CERA-20C is a centennial-scale reanalysis that assimilates both atmospheric and oceanic observations for the 1901–2010 period (Laloyaux et al., 2018). Such events changed the planetary climate for tens to hundreds of thousands of years, but at a rate that is actually much slower than projected anthropogenic climate change over this century, even in the absence of tipping points. 4); and unexpected biological epidemics among humans or other species, such as the COVID-19 pandemic (Cross-Chapter Box 6.

Common, integrating scenarios can never encompass all possible events that might induce radiative forcing in the future (Section 1. The change of season chapter 13. AR6 has adopted a unified framework of climate risk, supported by an increased focus in WGI on low-likelihood, high-impact outcomes. A well-known example is the modelled irreversibility of the ocean's thermohaline circulation in response to North Atlantic changes such as freshwater input from rainfall and ice-sheet melt (Rahmstorf et al., 2005; Alkhayuon et al., 2019), which is assessed in detail in Chapter 9 (Section 9.
In the Chapter starts with style list, select the heading style that was applied to the chapter heading. The resulting regional patterns of changes to precipitation are, however, different from surface temperature change, and interannual variability is larger, as illustrated in Figure 1. It does not stay below 2. In these experiments, atmospheric CO2 concentrations are calculated internally using the ESM interactive carbon cycle module and thus differ from the prescribed default CO2 concentrations used in the concentration-driven runs. 5°C above pre-industrial levels, recognizing that this would significantly reduce the risks and impacts of climate change.

For example, Hazeleger et al. The three main 'dimensions of integration' across Working Groups in AR6, that is, emissions scenarios, global warming levels and cumulative carbon emissions, are described in Section 1. 1, annex, paragraph 37].

Read Season of Change - Chapter 1. Argo is a global network of nearly 4000 autonomous profiling floats (Roemmich et al., 2019), delivering detailed constraints on the horizontal and vertical structure of temperature and salinity across the global ocean. Relative to 1850–1900 CE, the reconstructed GMST changed in the range of –6°C to +1°C across these glacial–interglacial cycles (see Chapter 2, Section 2.
It is important to evaluate the sensitivity of an analysis or assessment to the choice of the baseline. A further approach is to compare the results of process-based models with those from statistical models. Furthermore, the difference between narrower and wider uncertainty intervals has been shown to be confusing to lay readers, who often interpret wider intervals as less certain (Løhre et al., 2019).
