The Sahara Desert in North Africa is the largest hot desert in the world and is one of the hottest, driest and sunniest places on Earth. Located just south of the Sahara is a narrow semi-desert steppe (a semi-arid region) called the Sahel , while Africa's most southern areas contain both savanna plains , and its central portion, including the ...
Regardless of the time of day (i.e. Earth's rotation on its axis), the North Pole will be dark, and the South Pole will be illuminated; see also arctic winter. Figure 3 shows the angle of sunlight striking Earth in the Northern and Southern Hemispheres when Earth's northern axis is tilted away from the Sun, when it is winter in the north and ...
As the Sun becomes 10% brighter about one billion years from now, the surface temperature of Earth will reach 47 °C (117 °F) (unless Albedo is increased sufficiently), causing the temperature of Earth to rise rapidly and its oceans to boil away until it becomes a greenhouse planet, similar to Venus today.
Earth's energy budget (or Earth's energy balance) is the balance between the energy that Earth receives from the Sun and the energy the Earth loses back into outer space. Smaller energy sources, such as Earth's internal heat, are taken into consideration, but make a tiny contribution compared to solar energy.
Over the years the Earth's eccentricity has varied between 0.005 and 0.0607, today the eccentricity of Earth's orbit is approximately 0.0167. [5] While the value of eccentricity does impact the distance of the Earth from the Sun, its primary impact on insolation comes from its modulating effect on the procession cycle.

A swap would cost users $87.45 in gas fees on average, while non-fungible token (NFT) sales average $147 in gas. After the Ethereum Dencun upgrade this week, EIP-4844 will reduce L2 gas fees.
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 ...
