“…The authors attribute this reduced primary productivity to lower spring and summer temperatures. The peat stratigraphy presented by Mauquoy et al (2002) shows several wet shifts, mainly corresponding to periods with steep increases in D 14 C which are most likely a consequence of increased 14 C production as a result of low solar activity.…”

“…Their 1000-year long sediment record from the Norwegian Sea shows distinct 1-2°C decadal-to centennial-scale changes in sea surface temperatures that are strongly correlated to proxies of past solar activity. Additionally, Oldfield et al (1997) and Mauquoy et al (2002) found reduced carbon accumulation rates in Swedish and British peat bogs between~1400 and 1800 AD. The authors attribute this reduced primary productivity to lower spring and summer temperatures.…”

Natural climate change currently acts in concert with human-induced changes in the climate system. To disentangle the natural variability in the climate system and the human-induced effects on the global climate, a critical analysis of climate change in the past may offer a better understanding of the processes that drive the global climate system. In this review paper, we present palaeoclimatological evidence for the past influence of solar variability on Earth's climate, highlighting the effects of solar forcing on a range of timescales. On a decadal timescale, instrumental measurements as well as historical records show the effects of the 11-year Schwabe cycle on climate. The variation in total solar irradiance that is associated with a Schwabe cycle is only~1 W m À2 between a solar minimum and a maximum, but winter and spring temperatures on the Northern Hemisphere show a response even to this small-scale variability. There is a large body of evidence from palaeoclimatic reconstructions that shows the influence of solar activity on a centennial to millennial timescale. We highlight a period of low solar activity starting at 2800 years before present when Europe experienced a shift to colder and wetter climate conditions. The spatial pattern of climate change that can be recognized in the palaeoclimatological data is in line with the suggested pattern of climate change as simulated by climate models. Millennial-scale climate oscillations can be recognized in sediment records from the Atlantic Ocean as well as in records of lake-level fluctuations in southeastern France. These oscillations coincide with variation in 14 C production as recognized in the atmospheric 14 C record (which is a proxy-record for solar activity), suggesting that Earth's climate is sensitive to changes in solar activity on a millennial timescale as well.

“…Peatlands (i.e., soils accumulating partially decomposed plant remains with above 50% of organic matter and greater than 30 cm deep, Clymo, 1987) are continental archives of particular interest because they are easy to date, have a high temporal resolution (decadal) and contain multiple measurable parameters dependent on environmental conditions including temperature and/or humidity, atmospheric circulation and wind strength (e.g., Chambers et al, 2012). In particular ombrotrophic bogs are commonly used to reconstruct Holocene climate variability (e.g., Dupont, 1986;Hong et al, 2000;Shotyk et al, 2002;Mauquoy et al, 2002;Chambers and Charman, 2004;Roos-Barraclough et al, 2004;Sapkota et al, 2007;Lamentowicz et al, 2008;Moschen et al, 2011;Kylander et al, 2013). Ombrotrophic environments are hydrologically isolated from the surrounding landscapes; they receive all of their water and nutrients from precipitation (rain, snow, fog) and wind, with no influence from streams (e.g.…”

“…Moisture content of the Sphagnum mosses, water table depth, humification levels, macroremains and testate amoebae are directly linked to climate, and more specifically to the balance between evaporation and precipitation (e.g. McCarthy et al, 1995;Mauquoy et al, 2002;Barber et al, 2003;RoosBarraclough et al, 2004;Lamentowicz et al, 2008;Mitchell et al, 2008). The oxygen, carbon and deuterium stable isotope compositions of peat plant cellulose have been used to reconstruct air temperatures (Dupont, 1986;Hong et al, 2000;Moschen et al, 2011).…”

REE and lithogenic elements in addition to Nd and Pb isotopes were measured in a 173 cm age-dated peat profile and provide a continuous chronology of dust source and intensity. Calculated dust flux show pronounced increases c. 300 BC, 600 AD, 1000 AD, 1200 AD and from 1700 AD, corresponding to local and regional human activities combined with climate change.The Industrial Revolution samples (1700-1950 AD) are characterised by a significant enrichment in Sc-normalised REE abundance (sum REE/Sc > 25) due to intensive coal combustion. For the pre-Industrial Revolution samples, the Sc-normalised REE abundance (10 < Sum REE/Sc < 25) and the eNd variability (À13 to À9) are interpreted by a mixing between dust particles from local soils and long-range transport of desert particles. Three periods characterised by dominant-distal sources (c. 320 AD, 1000 AD and 1700 AD) are consistent with local wetter-than-average intervals as indicated by a lower degree of peat humification. Local erosion prevails during the drier (higher humification) intervals (100 AD, 600 AD). On a global scale, more distal supplies are driven during colder periods, in particular during the Oort and Maunder minima, suggesting a potential link between dust deposition and global climate. Combining REE abundance, fractionation between Light REE and Heavy REE and Nd isotope data in ombrotrophic peat allows one to distinguish between dust flux changes related to human and climate forcings.

This study compares age estimates of recent peat deposits in 10 European ombrotrophic (precipitation-fed) bogs produced using the 14 C bomb peak, 210 Pb, 137 Cs, spheroidal carbonaceous particles (SCPs), and pollen. At 3 sites, the results of the different dating methods agree well. In 5 cores, there is a clear discrepancy between the 14 C bomb peak and 210 Pb age estimates. In the upper layers of the profiles, the age estimates of 14 C and 210 Pb are in agreement. However, with increasing depth, the difference between the age estimates appears to become progressively greater. The evidence from the sites featured in the study suggests that, provided aboveground plant material (seeds, leaves) is selected for dating, the 14 C bomb peak is a reliable dating method, and is not significantly affected by the incorporation of old carbon with low 14 C content originating from sources including air pollution deposition or methane produced by peat decomposition. 210 Pb age estimates that are too old may be explained by the enrichment of 210 Pb activity in the surface layers of peat resulting from a hypothesized mechanism where rapidly infilling hollows, rich in binding sites, may scavenge 210 Pb associated with dissolved organic matter passing through the hollow, as part of the surface drainage network. Until further research identifies and resolves the cause of the inaccuracy in 210 Pb dating, age estimates of peat samples based only on 210 Pb should be used with caution. INTRODUCTIONThe increased human impact on the environment and climate during the last few centuries has given added importance to the reconstruction of environmental change during this period. In addition, the overlap between the environmental monitoring programs of the last 50-100 yr and paleoenvironmental data provides the opportunity to calibrate paleoenvironmental records (Charman and Garnett 2005). The high-precision dating of recen...
