Newfoundland (island) in the context of "European colonization of the Americas"

The Atlantic Ocean is the second largest of the world's five oceanic divisions, with an area of about 85,133,000 km (32,870,000 sq mi). It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe).

Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymous slave trade and the Columbian exchange while occasionally hosting naval battles. Such naval battles, as well as growing trade from regional American powers like the United States and Brazil, both increased in degree during the early 20th century. After World War II, major military operations became rarer, though notable postwar conflicts include the Cuban Missile Crisis and the Falklands War. The ocean remains a core component of trade around the world.

The Avalon explosion, named from the Precambrian faunal trace fossils discovered on the Avalon Peninsula in Newfoundland, eastern Canada, is a proposed evolutionary radiation of prehistoric animals about 575 million years ago in the Ediacaran period, with the Avalon explosion being one of three eras grouped in this time period. This evolutionary event is believed to have occurred some 33 million years earlier than the Cambrian explosion, which had been long thought to be when complex life started on Earth.

Scientists are still unsure of the full extent behind the development of the Avalon explosion, which resulted in a rapid increase in metazoan biodiversity, including the first appearance of some extant infrakingdoms/superphyla such as cnidarians and bilaterians. Many of the Avalon explosion animals are sessile soft-bodied organisms living in deep marine environments, and the first stages of the Avalon explosion were observed through comparatively minimal species.

British North America comprised the colonial territories of the British Empire in North America from 1783 onwards. English colonisation of North America began in the 16th century in Newfoundland, then further south at Roanoke and Jamestown, Virginia, and more substantially with the founding of the Thirteen Colonies along the Atlantic coast of North America.

The British Empire's colonial territories in North America were greatly expanded by the Treaty of Paris (1763), which formally concluded the Seven Years' War, referred to by the English colonies in North America as the French and Indian War, and by the French colonies as la Guerre de la Conquête. With the ultimate acquisition of most of New France (Nouvelle-France), British territory in North America was more than doubled in size, and the exclusion of France also dramatically altered the political landscape of the continent.

Captain James Cook (7 November 1728 – 14 February 1779) was a British Royal Navy officer, explorer, and cartographer who led three voyages of exploration to the Pacific and Southern Oceans between 1768 and 1779. He completed the first recorded circumnavigation of the main islands of New Zealand, and led the first recorded visit by Europeans to the east coast of Australia and the Hawaiian Islands.

Cook joined the British merchant navy as a teenager before enlisting in the Royal Navy in 1755. He first saw combat during the Seven Years' War, when he fought in the Siege of Louisbourg. Later in the war he surveyed and mapped much of the entrance to the St. Lawrence River during the Siege of Quebec. In the 1760s he mapped the coastline of Newfoundland and made important astronomical observations which brought him to the attention of the Admiralty and the Royal Society. This acclaim came at a pivotal moment in British overseas exploration, and it led to his commission in 1768 as commander of HMS Endeavour for the first of his three voyages.

The exploration of North America by Norsemen began in the late 10th century. Voyages from Iceland reached Greenland and founded colonies along its western coast. Norse settlements on Greenland lasted almost 500 years, and the population peaked at around 2,000–3,000 people. The colonies consisted mostly of farms along Greenland's scattered coastal fjords. Colonists relied heavily on hunting, especially of walruses and the harp seal. For lumber, they harvested driftwood, imported wood from Europe, and sailed to modern-day Canada.

Archaeological evidence indicates that the Greenland colonists used lumber and possibly iron ore imported from North America. Archaeologists found remains of one short-term settlement at L'Anse aux Meadows near the northern tip of Newfoundland. The remains of buildings excavated there in the 1960s dated to approximately 1,000 years ago. It was not a permanent settlement and lacked graves and livestock areas. The site was abandoned, seemingly deliberately, by 1145 AD with no valuables or tools left behind. Some wood fragments and nuts in the Norse remains were from plants not found in Newfoundland, but native to the continental mainland across the Gulf of St. Lawrence. No other settlements in Canada and no settlements on the North American mainland have been conclusively identified as Norse.

The Colony of Virginia was a British colonial settlement in North America from 1606 to 1776.

The first effort to create an English settlement in the area was chartered in 1584 and established in 1585; the resulting Roanoke Colony lasted for three attempts totaling six years. In 1590, the colony was abandoned. But nearly 20 years later, the colony was re-settled at Jamestown, not far north of the original site. A second charter was issued in 1606 and settled in 1607, becoming the first enduring English colony in North America. It followed failed attempts at settlement on Newfoundland by Sir Humphrey Gilbert in 1583 and the Roanoke Colony (in modern eastern North Carolina) by Sir Walter Raleigh in the late 1580s.

The climate of Ireland is mild, humid and changeable with abundant rainfall and a lack of temperature extremes. Ireland's climate is defined as a temperate oceanic climate, or Cfb on the Köppen climate classification system, a classification it shares with most of northwest Europe. The island receives generally warm summers and cool winters.

As Ireland is downwind of a large ocean, it is considerably milder in winter than other locations at the same latitude, for example Newfoundland in Canada or Sakhalin in Russia. The Atlantic overturning circulation, which includes ocean currents such as the North Atlantic Current and Gulf Stream, releases additional heat over the Atlantic, which is then carried by the prevailing winds towards Ireland giving, for example, Dublin a milder winter climate than other temperate oceanic climates in similar locations.
