This article analyzes some of the temporal and spatial categories we use to conceptualize and describe early modern North America. Some of our most significant spatial and temporal categories – in particular, "colonies" and "colonial"– are products of the historiography of the rise of the ...

Radioisotopic dating of volcanic minerals is a powerful method for establishing absolute time constraints in sedimentary basins, which improves our understanding of the chronostratigraphy and evolution of basin processes. The relative plate motions of Greenland, North America, and Eurasia changed several ...
At the same time, winter sea surface temperatures cooled, winter floating ice became more abundant and global climate descended into glacial conditions. We suggest that the observed summer warming extended into the autumn, providing water vapour to northern North America, where it precipitated and ...
摘要: Cyclone tracks over the Great Lakes of North America shift, both East–West as well as North–South. The reasons for the shifts are various small-scale as well as large-scale processes associated with...DOI: 10.1007/s11069-018-3429-2 年份: 2018 ...
During the mid-Holocene, the vegetation cover changed substantially (Prentice and Webb III, 1998; Lin et al., 2019); for example, there was a northward extension of boreal forest over northern Eurasia and North America, in response to increased temperatures in mid- to high-latitude (MacDonald...

The U.S. Southwest relies on the increasingly erratic seasonal phenomenon to help fight wildfires and drought. Now researchers are getting better at predicting it.
In summary, the results of our quantitative analyses are consistent with climate-driven declines in North America’s megafauna populations. Data quality issues aside (see Introduction), using the largest assembled database of directly dated megafauna, we found no through-time relationship between megafa...
摘要: U–Pb–Lu–Hf of detrital zircons from the south-central part of the NCC is presented.A dramatic Late Carboniferous provenance shift was recorded by detrital zircons.Old crustal components are underestimated for growth model based on young sediments....
