Climatic change in northern Canada

Abstract: Climatic variations during the past 10 000 and 1 000 years in the Canadian Arctic are recorded in a variety of proxy-climate records. Paleoclimates of the past 1000 years are interpreted from ice cores, lake sediments, and primarily tree rings. The past 500 years, between A.D. 1500 and A.D. 1850 were relatively cool, with coolest temperatures in the 1600s and 1800s. In the 1700s temperatures were slightly warmer, but still not as warm as the latter half of the 20th Century. Warming in the 20th century is also … Show more

“…years ). Period I, characterized by contemporaneous wet phases in all three cores, and associated with significantly lower values of percentage melt (BY-LowC, BY-HighC and BY-a) and δ 18 O (BY-a), is broadly coeval with a period of climatic cooling well documented from sites in the North Atlantic region (Lamb 1965;Williams & Wigley 1983;Millar & Woolfenden 1999) including the Arctic (Williams & Wigley 1983;Gajewski & Atkinson 2003): i.e. the Little Ice Age (LIA).…”

“…The general conclusion is that warmest temperatures occurred earlier in the Holocene, and this is based on multiproxy records from dozens of sites and is consistent between proxies. Maximum temperatures were identified in the early to mid-Holocene prior to 5200 cal yr BP, with the timing depending on region and this is documented in lake sediment records (Bradley 1990;Gajewski and Atkinson 2003;Kaufman et al 2004;Gajewski 2015a;Briner et al 2016), ice cores (Devon Ice Cap, Koerner and Fisher 1985;Agassiz Ice Cap, Fisher et al 1995;Vinther et al 2009), fossil whalebone distributions (Dyke et al 1996), and pollen diagrams (Gajewski 1995(Gajewski , 2015a(Gajewski , 2015bGajewski et al 2000;Gajewski and Frappier 2001;Zabenskie and Gajewski 2007;Peros and Gajewski 2008b;Peros et al 2010). Gajewski (2015a) provided a quantitative summary of the climates of the Canadian Arctic and Greenland and found warmest temperatures before 8000 cal yr BP in the western and central Arctic, between 8000 and 5000 cal yr BP in the eastern Arctic and most of Greenland, and later in South Greenland.…”

“…5) are available from the International Tree-Ring Data Bank (ITRDB) (Cropper and Fritts, 1981;NOAA -NCDC, 2012). Briffa et al (1992), Schweingruber et al (1993), and Gajewski and Atkinson (2003) examined these series in relation to other data from northern North America. Other series include chronologies from the tree line (Ayotte, 2002) and the forest interior (Zalatan and Gajewski, 2005), and all sites show common trends that can be associated with regional-scale climate impacts on tree growth.…”
