text: The researchers collected pollen spores from sediment cores taken from a lake (referred to as JR01 in Figure 2) in Nunavut. They made the appropriate measurements and statistical analyses to link the pollen pattern through time to variations in local temperatures. Surprisingly (to some) they find Reconstructed mean July temperatures remained around 6.6 C before 5700 cal yr BP. July temperatures then increased to 7.8C between 5700 and 3800 cal yr BP and temperatures have decreased slightly during the past 3800 yr and Maximum estimated July temperatures were reached between 5800 and 3000 cal yr BP, at which time they exceeded present-day values. Finally Reconstructions of July temperature using the modern analog technique showed that the mid-Holocene (58002800 cal yr BP) was approximately 1C higher than during the past 1000 yr. See Figure 3, for their temperature reconstruction.
