Explanation:Most of the increase in global temperatures since 1950 has been caused by human activity.
The average temperature of the Earth is determined by the greenhouse effect.Global temperatures have increased by about 1° Celsius in the past century.
The EMS that is radiated from the sun in the form of solar rays reaches the earth and is absorbed in various places on the earth thus creating an energy balance with the incoming and the outgoing energy that is again reflected space in the form of long-wave terrestrial radiation.
The sun's energy is not distributed equally as the tilt of the earth and at the onset of the sunlight that falls directly on earth which is equivalent to one billionth of a fraction of energy that the sun radiates in the form of corpuscular energy.
Energy fall of the earth is 100% in which the outer surface reflects 35 units to space, 27 forms the cloud top, 2% form the snow and ice. 6% of the units by the inner atmosphere and the 65 % units get absorbed.14% in air and 50% in the ground, thus the atmosphere absorbs about 48% of the units.
We can never observe free-fall in our daily life on Earth. There's always at least one other force besides gravity acting on a falling body, because it's always falling through air.
