«We found compelling evidence that invasive shrubs, such as Japanese barberry, are ready to leaf out quickly once they are exposed to warm temperatures in the lab even in the middle of winter, whereas native shrubs, like highbush bluberry, and native trees, like red maple, need to go through a longer winter chilling period before they can leaf out — and even then their response is slow,» says Amanda Gallinat, a second - year graduate student and third author of the paper.

The sediment cores used in this study cover a period when the planet went through many climate cycles driven by variations in Earth's orbit, from extreme glacial periods such as the Last Glacial Maximum about 20,000 years ago, when massive ice sheets covered the northern parts of Europe and North America, to relatively warm interglacial periods with climates more like today's.

Bacteria, however, have remained Earth's most successful form of life — found miles deep below as well as within and on surface rock, within and beneath the oceans and polar ice, floating in the air, and within as well as on Homo sapiens sapiens; and some Arctic thermophiles apparently even have life - cycle hibernation periods of up to a 100 million years while waiting for warmer conditions underneath increasing layers of sea sediments (Lewis Dartnell, New Scientist, September 20, 2010; and Hubert et al, 2010).

As discussed elsewhere on this site, modeling studies indicate that the modest cooling of hemispheric or global mean temperatures during the 15th - 19th centuries (relative to the warmer temperatures of the 11th - 14th centuries) appears to have been associated with a combination of lowered solar irradiance and a particularly intense period of explosive volcanic activity.

As alluded to in our post, one important issue is the possibility that changes in El Nino may have significantly offset opposite temperature variations in the extratropics, moderating the influence of the extratropical «Little Ice Age» and «Medieval Warm Period» on hemispheric or global mean temperatures (e.g. Cobb et al (2003).

As a consequence, their results are strongly influenced by the low increase in observed warming during the past decade (about 0.05 °C / decade in the 1998 — 2012 period compared to about 0.12 °C / decade from 1951 to 2012, see IPCC 2013), and therewith possibly also by the incomplete coverage of global temperature observations (Cowtan and Way 2013).

Periods of volcanism can cool the climate (as with the 1991 Pinatubo eruption), methane emissions from increased biological activity can warm the climate, and slight changes in solar output and orbital variations can all have climate effects which are much shorter in duration than the ice age cycles, ranging from less than a decade to a thousand years in duration (the Younger Dryas).
