Meaning: The quote by Harry Johnston, an explorer, highlights the surprising habitability of Iceland despite its northern location. It draws attention to the influence of the Gulf Stream on the climate of Iceland, noting that, like Norway, Scotland, and Ireland, the country is affected by this warm ocean current. This quote is significant because it challenges the common perception of Iceland as a cold and inhospitable place due to its high latitude.

Iceland is indeed located at a high latitude, with parts of the country extending into the Arctic Circle. This geographical position would typically lead to very cold and harsh conditions. However, the Gulf Stream, a powerful and warm ocean current originating in the Gulf of Mexico, has a significant impact on the climate of Iceland. As the Gulf Stream flows northeastward along the coast of North America before turning eastward toward Europe, it brings relatively warm water and air to the northern regions it influences. This results in a moderating effect on the climate, leading to milder temperatures than would be expected at such high latitudes.

The Gulf Stream's influence on Iceland's climate is particularly notable along the southern and western coasts of the country. These areas experience a maritime climate characterized by relatively mild winters and cool summers. The moderating effect of the Gulf Stream helps to prevent extreme temperature fluctuations, contributing to the habitability of these regions. As a result, considerable portions of Iceland are indeed quite habitable, as noted by Harry Johnston in the quote.

The comparison to Norway, Scotland, and Ireland in the quote is also significant. These countries share a similar northern latitude and are also affected by the Gulf Stream, leading to comparable climatic conditions. Norway, for example, experiences relatively mild coastal climates in the western parts influenced by the Gulf Stream. Similarly, Scotland and Ireland benefit from the moderating influence of the ocean current, leading to milder temperatures and more hospitable conditions than might be expected at their latitudes.

It is worth noting that while the Gulf Stream plays a crucial role in shaping the climates of these regions, it is not the sole factor influencing their habitability. Other geographical and meteorological factors also contribute to the overall climate and environmental conditions. Nonetheless, the quote effectively highlights the unexpected habitability of Iceland and emphasizes the importance of understanding the complex interactions between ocean currents, geography, and climate.

In conclusion, Harry Johnston's quote draws attention to the surprising habitability of Iceland, despite its high latitude and proximity to the Arctic Circle. The influence of the Gulf Stream on the country's climate, similar to its effects on Norway, Scotland, and Ireland, plays a crucial role in creating habitable conditions in considerable portions of Iceland. By recognizing this influence, the quote challenges common perceptions and reminds us of the intricate relationships between ocean currents and climate, ultimately contributing to a deeper understanding of the environmental diversity found across the globe.
