Without some distinct evidence to the contrary, we may at least admit as probable that the glacial action was simultaneous on the eastern and western sides of North America, in the Cordillera under the equator and under the warmer temperate zones, and on both sides of the southern extremity of the continent.
Hence we see that throughout the world, the plants growing on the more lofty mountains, and on the temperate lowlands of the northern and southern hemispheres, are sometimes identically the same; but they are much oftener specifically distinct, though related to each other in a most remarkable manner.
It should be observed that the northern species and forms found in the southern parts of the southern hemisphere, and on the mountain-ranges of the intertropical regions, are not arctic, but belong to the northern temperate zones.
As the cold came slowly on, all the tropical plants and other productions will have retreated from both sides towards the equator, followed in the rear by the temperate productions, and these by the arctic; but with the latter we are not now concerned.
Thus, as I believe, a considerable number of plants, a few terrestrial animals, and some marine productions, migrated during the Glacial period from the northern and southern temperate zones into the intertropical regions, and some even crossed the equator.
I am far from supposing that all difficulties are removed on the view here given in regard to the range and affinities of the allied species which live in the northern and southern temperate zones and on the mountains of the intertropical regions.
26, 2015 /PRNewswire/ -- International climate change and rainforest experts warned that without drastic and immediate cuts to greenhouse gas emissions and new forest protections, the world's most expansive stretch of temperate
rainforests from Alaska to the coast redwoods will experience irreparable losses.
The standard climate change predictions said that people in the tropics and the sub-tropics would be badly hurt by global warming long before the people living in the temperate
zones, farther away from the equator, were feeling much pain at all.
Summary: The month of November will be characterized by temperate
weather during day times and temperature tends to be low at nights in the UAE, according to the National Center of Meteorology & Seismology (NCMS).
