What is climate? Climate is a state of physical nature characterized by a temperature or climate condition that is repeated over time. Climate is also the mean and variation of atmospheric variables over an extended period of time, usually averaging more than a year. In its most basic terms, the climate is defined as a condition that can endure for an extended period of time, where neither extreme of either temperature or precipitation is experienced.
There are many contributors to climate. Although human activities are currently the greatest cause of climate change, natural climate variations may have caused changes in the Earth’s climate in the distant past. Evidence of past climate is easily detected in ice cores, coral reefs and lake shells. Other physical processes such as ocean currents, wind, and the expansion and contraction of gasses, all have important effects on the Earth’s climate. Earth’s orbit and tilt also affect global temperatures.
Global climate is continuously changing. Recent research indicates that the Earth’s climate system is highly dynamic. Rapid changes in climate occur because the Earth’s atmosphere is spread into different layers, with some cooler at the top and warmer at the base. Cooler air absorbs heat from the sun, which warms the Earth’s surface. Warming causes precipitation, the precipitation determines the frequency and intensity of seasonal climate fluctuations. Rapid changes also bring about global warming, the warming of the atmosphere above the earth’s surface.
As mentioned above, the climate varies dramatically over time. It can go from cold to hot, sunny to rainy, and windy to calm. The Earth’s average temperature varies through the seasons and day/night variations through the Earth’s interior. These short-lived climate changes sometimes are associated with natural phenomena such as ocean currents, which are brought about by external factors such as clouds, rain, or snowfall. For instance, changes in ocean currents may increase the speed and duration of tropical storms and reduce hurricane strength.
Global average temperatures rise and fall. In the winter months, they dip below freezing and remain close to freezing until late in the spring. In summer, daytime temperatures rise, while nighttime temperatures drop below freezing. The rapid climate changes caused by human activities have led to the concentrations of greenhouse gases like carbon dioxide, methane, and coal dioxide in the atmosphere being unusually high.
Global warming is a result of human activities leading to the emission of greenhouse gases and disruption of the earth’s climate. Although natural cycles take care of climate change, human activities have sped up climate change. The rapid expansion of the human population has been one of the important factors behind climate change. Moreover, mankind has increased the atmospheric concentration of greenhouse gases, which act as a catalyst for climate change. Another factor behind climate change is global warming, which is observed on a regional scale.
The earth obtains an amount of heat energy each day equal to the weight of 2.1 tons of material. Most of the heat energy escapes through surface water, the land, and the ocean. On a climatic spectrum, green means that the earth is experiencing a warm climate and red means that the earth is experiencing a cold climate. A warm climate is caused by natural factors like the lapse of seasons, internal atmospheric pressure, and cloud cover.
The atmosphere exchanges substances with the earths atmosphere, known as exchanging heat energy. The earth obtains an amount of heat energy equal to the weight of 2.1 tons of material daily. Most of the heat energy escapes through the land, surface water, and ocean. On a climatic spectrum, green means that the earth is experiencing a warm climate, red means that the earth is experiencing a cold climate, and that there is a possibility of changing climates. Green means that the climate system is able to regulate itself, red means that the climate system is able to change rapidly, and that clouds are forming in areas of cold climates.
