“…The high representation of Madhuca indica and Sapotaceae has also been recorded from the study of surface samples from Sapna Lake, Betul District (Chauhan & Quamar 2012). However, Madhuca indica, Holoptelea, Lannea coromandelica, Emblica officinalis, Terminalia, are also recorded in moderate values from Khedla Quila Lake samples (Quamar & Chauhan 2013b), whereas Sapotaceae Schrebera and Sterculia are sporadic. Flacourtia and Butea monosperma have high frequencies because of their local preponderance.…”

The present communication reviews the pattern of modern pollen-rain studies carried out in southwestern Madhya Pradesh, India. The study largely revealed that Tectona grandis (teak), despite being an enormous pollen producer (7500 average number of absolute pollen/flower) and the dominant forest constituent (80 to 95% of the total forest constituents), is recorded mostly in low frequencies, attributable to its low pollen dispersal efficiency as well as poor pollen preservation in the sediments. However, Madhuca indica (Mahua) and other dominant members of Sapotaceae (cf. Manilkara hexandra and Mimusops elangi) have always shown their typical behaviour in the pollen spectra and are represented in high frequencies, which are assigned to their local abundance around the provenance of the samples, coupled with high dispersal efficiency as well as good pollen preservation in the sediments. Meanwhile, the other usual and characteristic associates of teak (Tectona grandis) in the tropical deciduous forests, despite being the common elements of the forests, are under-represented, sporadically represented or not represented at all, which could be ascribed to their low pollen productivity owing to entomogamy. Various factors that affect the deposition pattern of the diverse constituents of the tropical deciduous forests dominated by teak (Tectona grandis) have been discussed and suggestions are also given while interpreting the pollen sequences generated from the sedimentary beds in terms of past vegetation and climate in a chronological order in the region during the Late Quaternary Period.

“…With the varying chronological resolution, the central India (Sinha et al, 2007(Sinha et al, , 2011, lesser Himalaya (Kotlia et al, 2015;Sinha et al, 2015) and Arabian Sea (Chauhan et al, 2010;Gupta et al, 2003) records demonstrated a declining ISM with the onset of MWP followed by ISM strengthening during MWP (Dixit and Tandon, 2016). In general, the MWP of the last millennium has been identified as ISM strengthening period as suggested by marine (Agnihotri et al, 2002(Agnihotri et al, , 2003aChauhan et al, 2010;Gupta et al, 2003) and continental (Banerji et al, 2017(Banerji et al, , 2019Quamar and Chauhan, 2014;Rawat et al, 2015b;Rühland et al, 2006;Sridhar, 2009) records which was followed by ISM weakening by the end of MWP (Dixit and Tandon, 2016). In addition, the studies have also demonstrated the occurrence of major droughts during both onset and closing of MWP from central India (Sinha et al, 2011) which nearly corroborated well with the oxygen isotope-based stalagmite study from Andamans (Laskar et al, 2013b) and marine records from the Arabian Sea (Tiwari et al, 2005a).…”

“…Most of the marine and continental records from the Arabian Sea and peninsular India demonstrated a dry climate as a result of ISM weakening (Agnihotri et al, 2002;Menzel et al, 2014). On the contrary, the wet climate has been invoked for Madhya Pradesh (Quamar and Chauhan, 2014), Gujarat (Banerji et al, 2017(Banerji et al, , 2019Sridhar et al, 2015) and central Himalayas (Kotlia et al, 2015;Sinha et al, 2015) (Figure 6). Global evidence has associated the LIA with southward migration of ITCZ (Banerji et al, 2019;Brown and Johnson, 2005;Konecky et al, 2013a;Newton et al, 2011).…”

Holocene climate variability and Indian Summer Monsoon: An overview

2020

The response of the Indian Summer Monsoon (ISM) to forcing factors and climate variables has not yet fully explored, even though the ISM plays a pivotal role in the socio-economics of the Indian subcontinent and nearby areas. The ISM progression over Indian landmass is a manifestation of the Intertropical Convergence Zone (ITCZ) migration over the northern Indian Ocean and the Indian subcontinent. The recent anomalous behaviour of ISM raises the need for a better understanding of its spatio-temporal changes during the ongoing interglacial period termed as the Holocene period. The Holocene period has been classified further based on the globally observed abrupt climatic events at 8.2 and 4.2 ka. The 8.2 ka global cooling events have been recorded from northern Indian Ocean marine archives but limited records from the continental archives of the Indian landmass has demonstrated the 8.2 ka event. At the same time, the 4.2 ka dry climate has been endorsed by both marine as well as continental records and agrees with the global studies. During the ‘Little Ice Age’ (LIA), in the India subcontinent, wet conditions prevailed in the northern, central and western regions while a dry climate existed over the greater part of peninsular India. The present review offers an account of ISM signatures and possible mechanisms associated with the monsoon variability in the Indian subcontinent and the northern Indian Ocean during the Holocene period.

“…The late Holocene is an important time period as it contains some major global and regional climatic variability, i.e. the Medieval Warm Period (MWP; Polovodova et al, 2011;Quamar and Chauhan, 2014), the Little Ice Age (LIA; Mann, 2002;Ponce et al, 2017), and 20th-century global warming, during a period when large-scale climate parameters such as ocean circulation and ice sheet extent were broadly similar to today. There is progress in hemispheric (Beltrami and Bourlon, 2004;Neukom and Gergis, 2011) and global (Huang et al, 2000) average temperature estimation over the last millennia, but there are still significant uncertainties in understanding regional responses to global anthropogenic effect (Mann et al, 2009).…”

Late Holocene temperature variability in Tasmania inferred from borehole temperature data

2017

Abstract. Thirty-six borehole temperature–depth profiles were analysed to reconstruct the ground surface temperature history (GSTH) of eastern Tasmania for the past 5 centuries. We used the singular value decomposition method to invert borehole temperatures to produce temperature histories. The quality of borehole data was classified as high or low based on model misfit. The quality of the borehole data was not dependent on topography or land use. Analysis reveals that three to five high-quality borehole temperature–depth profiles were adequate to reconstruct robust paleotemperature records from any area. Average GSTH reconstructed from Tasmanian boreholes shows temperature increases about 1.2 ± 0.2 °C during the past 5 centuries. Reconstructed temperatures were consistent with meteorological records and other proxy records from Tasmania during their period of overlap. Temperature changes were greatest around the north-east coast and decreased towards the centre of Tasmania. The extension of the East Australian Current (EAC) further south and its strengthening around the north-east coast of Tasmania over the past century was considered a prime driver of warmer temperatures observed in north-east Tasmania.
