Africa is often considered and referred as the "Sun continent" or the continent where the Sun's influence is the greatest. [2] According to the "World Sunshine Map", Africa receives many more hours of bright sunshine during the course of the year than any other continent of the Earth: [3] and many of the sunniest countries on the planet are in ...
In 2002, Lean et al. [41] stated that while "There is ... growing empirical evidence for the Sun's role in climate change on multiple time scales including the 11-year cycle", "changes in terrestrial proxies of solar activity (such as the 14C and 10Be cosmogenic isotopes and the aa geomagnetic index) can occur in the absence of long-term (i.e ...
World map of global solar horizontal irradiation [1] Africa receives the most sunlight in comparison to all the other continents on Earth, especially as there are many perpetually sunny areas like the huge Sahara Desert. [12] It has much greater solar resources than any other continent.
The projection effect can be used to design buildings that are cool in summer and warm in winter, by providing vertical windows on the equator-facing side of the building (the south face in the northern hemisphere, or the north face in the southern hemisphere): this maximizes insolation in the winter months when the Sun is low in the sky and ...
The Sun is a star located at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma and magnetic fields . [ 3 ] [ 4 ] It has a diameter of about 1,392,684 kilometres (865,374 mi), [ 5 ] around 109 times that of Earth , and its mass (1.989 × 10 30 kilograms, approximately 330,000 times that of Earth ...
The amount of heat energy received at any location on the globe is a direct effect of Sun angle on climate, as the angle at which sunlight strikes Earth varies by location, time of day, and season due to Earth's orbit around the Sun and Earth's rotation around its tilted axis.
At best, it’s viewed as a means of temporarily staving off the direst weather effects of climate change while the world carries out the lengthy and expensive effort of decarbonizing the global ...
Climate change in Africa is an increasingly serious threat as Africa is among the most vulnerable continents to the effects of climate change. [1] [2] [3] Some sources even classify Africa as "the most vulnerable continent on Earth". [4] [5] Climate change and climate variability will likely reduce agricultural production, food security and ...
