(8) Ultimately, the occupation of the Western Hemisphere was a direct result of boreal cultural adaptations in the Old World.
(9) The high northern latitudes are warming more rapidly than other parts of the Earth, with climate models predicting a northward shift of Arctic vegetation that will see the boreal biome (coniferous forest across North America and Eurasia) migrate into what is currently tundra (treeless plains of the Arctic).
(10) But the ‘Boreal’ (Norway, Finland and the Baltics) and ‘Atlantic’ (UK, Western France, Denmark and Benelux countries) emerge as danger spots for biodiversity.

(17) Surrounded by boreal forest, it is one of the most spectacularly beautiful regions in Canada.
(18) If global warming is leading to more fires in boreal forests, which in turn leads to more emissions from those forests, which in turn leads to more climate change.
(19) Boreal forests are one of the world’s great carbon sinks.

Definition:
(n.) The north wind; -- usually a personification.

(3) The mean time spent by individual B. boreas tadpoles in the half of the test tank to which the extract solution was added was significantly lower than expected by chance.
(4) Trypanosoma fallisi is morphologically similar to T. bufophlebotomi described in Bufo boreas from California, but geographic isolation, host and vector differences as well as slight morphological differences indicate that speciation has occurred.
(5) The Weather Channel, which is calling the storm “Boreas” – after the Greek god of the cold north wind who once fathered 12 horses after taking the form of a stallion – said the storm was “spreading its wintry mess” of snow, sleet and freezing rain into the east.
