Observed increases in the frequency and intensity of heavy precipitation events in most parts of the United States are projected to continue (high confidence). Limited observational records affect the ability to accurately estimate the contribution of natural decadal to multi-decadal variability on observed expansion of the tropics. 2004275,276), which were cited in the Third National Climate Assessment, as well as those cited in this assessment. Permafrost thaw is occurring faster than models predict due to poorly understood deep soil, ice wedge, and thermokarst processes.125,282,285,292 Additional uncertainty stems from the surprising uptake of methane from mineral soils293 and dependence of emissions on vegetation and soil properties.294 The observational and modeling evidence supports the Key Message that the permafrost–carbon feedback is positive (i.e., amplifies warming). 2021. Many lines of evidence demonstrate that human activities, especially emissions of greenhouse gases from fossil fuel combustion, deforestation, and land-use change, are primarily responsible for the climate changes observed in the industrial era, especially over the last six decades.

Global climate is changing rapidly compared to the pace of natural variations in climate that have occurred throughout Earth’s history. Observed warming over the period 1951–2010 was 1.2°F (0.65°C), and formal detection and attribution studies conclude that the likely range of the human contribution to the global average temperature increase over the period 1951–2010 is 1.1°F to 1.4°F (0.6°C to 0.8°C;15 see Knutson et al.

This time around, the canvas take on the court classic features a clean white base paired with contrasting blue overlays. Under higher future scenarios, assuming no change to current water resources management, snow-dominated watersheds in the western United States are more likely to experience lengthy and chronic hydrological drought conditions by the end of this century.105,106,107, Across much of the United States, surface soil moisture is projected to decrease as the climate warms, driven largely by increased evaporation rates due to warmer temperatures. U.S. 2017,94 Figures 7.2 and 7.3). Thawing permafrost makes previously frozen organic matter available for microbial decomposition. Annual average temperature over the contiguous United States has increased by 1.2ºF (0.7°C) over the last few decades and by 1.8°F (1°C) relative to the beginning of the last century.

D., 2007: Hydrographic Atlas of the World Ocean Circulation Experiment (WOCE). With significant reductions in emissions, global temperature increase could be limited to 3.6°F (2°C) or less compared to preindustrial temperatures. First, the ability of four hurricanes—Harvey, Irma, Jose, and Maria (Figure 2.9)—to rapidly reach and maintain very high intensity was anomalous and, in one case, unprecedented. Observed changes in other aspects of atmospheric circulation include the northward shift in winter storm tracks since detailed observations began in the 1950s and an associated poleward shift of the subtropical dry zones.151,152,153 In the future, some studies show increases in the frequency of the most intense winter storms over the northeastern United States (e.g., Colle et al. 9: Oceans; Ch. The last few years have also seen record-breaking, climate-related weather extremes. Global average temperature has increased by about 1.8°F from 1901 to 2016, and observational evidence does not support any credible natural explanations for this amount of warming; instead, the evidence consistently points to human activities, especially emissions of greenhouse or heat-trapping gases, as the dominant cause.

Additionally, climate models capture the enhanced warming in the Arctic, indicating a solid understanding of the underlying physical mechanisms. Earthquakes. This carbon uptake is making near-surface ocean waters more acidic, which in turn can harm vulnerable marine ecosystems (see Ch. Beyond the next few decades, how much the climate changes will depend primarily on the amount of greenhouse gases emitted into the atmosphere; how much of those greenhouse gases are absorbed by the ocean, the biosphere, and other sinks; and how sensitive Earth’s climate is to those emissions.23 Climate sensitivity is typically defined as the long-term change that would result from a doubling of carbon dioxide in the atmosphere relative to preindustrial levels; its exact value is uncertain due to the interconnected nature of the land–atmosphere–ocean system.

Several avenues of research, including emerging science on physical feedbacks in the Antarctic ice sheet (e.g., DeConto and Pollard 2016, Kopp et al. In the Arctic, annual average temperatures have increased more than twice as fast as the global average, accompanied by thawing permafrost and loss of sea ice and glacier mass. With significant reductions in emissions, global temperature increase could be limited to 3.6°F (2°C) or less compared to preindustrial temperatures (high confidence). Wahl, E. R., and J. E.

There is high confidence in warming trends of the upper ocean temperature from 0–700 m depth, whereas there is more uncertainty for deeper ocean depths of 700–2,000 m due to the short record of measurements from those areas. 2014, sensitivity study; Jevrejeva et al. 4th edition. Observed trends in a broad range of physical climate indicators show that Earth is warming. Confidence is very high in the rate of GMSL rise since 1900, based on multiple different approaches to estimating GMSL rise from tide gauges and satellite altimetry. Recent model projections for the eastern United States also confirm a future shift from snowfall to rainfall during the cold season in colder portions of the central and eastern United States. B.

Wittenberg, 2014: Seasonal and annual mean precipitation extremes occurring during 2013: A U.S. focused analysis [in “Explaining Extreme Events of 2013 from a Climate Perspective”]. However, this increase in solar forcing uncertainty is not sufficiently large to reduce confidence that anthropogenic activities dominate industrial-era forcing. Recent studies have linked record warm temperatures in the Arctic to changes in atmospheric circulation patterns in the midlatitudes.122,150. Most of the climate projections used in this assessment are based on simulations by global climate models (GCMs). These multiple lines of evidence provide very high confidence of enhanced arctic warming with potentially significant impacts on coastal communities and marine ecosystems. For this reason, there is significant potential for humankind’s planetary experiment to result in surprises—and the further and faster Earth’s climate system is changed, the greater the risk of unanticipated changes and impacts, some of which are potentially large and irreversible.

Coumou, 2017: Influence of anthropogenic climate change on planetary wave resonance and extreme weather events. The largest source of uncertainty in radiative forcing (both natural and anthropogenic) over the industrial era is quantifying forcing by aerosols. However, certain aspects of the 2017 season were unprecedented, and at least two of these aspects are consistent with what might be expected as the planet warms. 1. Allen, J. T., and M. K. Tippett, 2015: The Characteristics of United States Hail Reports: 1955-2014. Over the last 50 years, declining oxygen levels have been observed in many inland seas, estuaries, and nearshore coastal waters.43,45,46,47,48,49,50,51,52 This is a concern because oxygen is essential to most life in the ocean, governing a host of biogeochemical and biological processes that ultimately shape the composition, diversity, abundance, and distribution of organisms from microbes to whales.34, By 2100, under a higher scenario (RCP8.5; see Box 2.4), average SST is projected to increase by 4.9° ± 1.3°F (2.7° ± 0.7°C) as compared to late 20th-century values, ocean oxygen levels are projected to decrease by 3.5%,53 and global average surface ocean acidity is projected to increase by 100% to 150%.32 This rate of acidification would be unparalleled in at least the past 66 million years.34,54,55, Since 1900, global average sea level has risen by about 7–8 inches (about 16–21 cm). (2008)261 constructed a “worst-case” 2.0 m scenario, based on acceleration of mass loss from Greenland, that assumed a 30 cm GMSL contribution from thermal expansion. Along U.S. coastlines, how much and how fast sea level rises will not just depend on global trends; it will also be affected by changes in ocean circulation, land elevation, and the rotation and the gravitational field of Earth, which are affected by how much land ice melts, and where. Additional increases in annual average temperature of about 2.5°F (1.4°C) are expected over the next few decades regardless of future emissions, and increases ranging from 3°F to 12°F (1.6°–6.6°C) are expected by the end of century, depending on whether the world follows a higher or lower future scenario, with proportionally greater changes in high temperature extremes (high confidence). Humanity’s effect on Earth’s climate system since the start of the industrial era, through the large-scale combustion of fossil fuels, widespread deforestation, and other activities, is unprecedented. There is very high confidence for continued changes in climate and high confidence for the levels shown in the Key Message. Nerem, R. S., D. P. Chambers, C. Choe, and G. T. Mitchum, 2010: Estimating mean sea level change from the TOPEX and Jason altimeter missions. Projections of future changes are based on simulations from global climate models, downscaled to higher resolutions more relevant to local- to regional-scale impacts. Delworth, T. L., F. Zeng, G. A. Vecchi, X. Yang, L. Zhang, and R. Zhang, 2016: The North Atlantic Oscillation as a driver of rapid climate change in the Northern Hemisphere. One of the key ways this is happening is through changes in atmospheric circulation patterns. Hodgkins, G. A., P. H. Whitfield, D. H. Burn, J. Hannaford, B. Renard, K. Stahl, A. K. Fleig, H. Madsen, L. Mediero, J. Korhonen, C. Murphy, and D. Wilson, 2017: Climate-driven variability in the occurrence of major floods across North America and Europe. Rate. On Earth, we're protected by our magnetic field, but out in space, this would have been hazardous for the astronauts. For heavy precipitation events above the 99th percentile of daily values, observed changes for the Northeast and Midwest average 38% and 39%, respectively, when measured from 1901, and 55% and 42%, respectively, when measured with the more robust network available from 1958. Due to possibly large ice sheet contributions, there is low confidence in the upper end of very likely ranges for 2100. Other types of extreme weather, such as tornadoes, hail, and thunderstorms, are also exhibiting changes that may be related to climate change, but scientific understanding is not yet detailed enough to confidently project the direction and magnitude of future change.172, For example, tornado activity in the United States has become more variable, particularly over the 2000s (e.g., Tippett 2014, Elsner et al. Horton, R. M., V. Gornitz, D. A. Bader, A. C. Ruane, R. Goldberg, and C.
