What is a natural climate change?
While human activity from the industrial revolution in the 17th century was driven by recent global warming, there is also a natural climate change that occurs due to normal atmospheric changes. Climate change usually concerns permanent weather changes around the world, although it can be limited to the region. Natural climate change can be caused by several factors or climate for the climate, including the tectonics of the albums, the ocean variations, the tilt of the planet, orbital fluctuations and changes in solar production. Scientists often use glaciers as a lens for the past natural climate change, dating when the glacier proceeded, indicating cold charm or receding, indicating a period of heat. Ice core samples also throw light in ancient weather by providing information about the amount of carbon dioxide that was in the atmosphere at the time. Fossils of plants, animals, insects and pollen can also be used for the date of climatic cycles because certain species survive under different conditions. This evidence shows the climateCycle marked with ice age and heat periods extending far back to prehistoric times.
One important reason for natural climate change can be attributed to tectonics board and continental drift. Just below the ocean and continental crusts or parts of the country that people can see, the rigid layer of the Earth, called lithosphere lies. The lithosphere is divided into plates that move through a deeper, warmer and more liquid layer. These boards cause restructuring of the mainland, especially at the borders where the plates can crush, causing earthquakes, giving up each other, causing earthquakes and geothermal hotspots or colliding with others, causing earthquakes, Mountain ranges, volcanoes and ocean trenches. This restructuring moves the mainland from one region of the world to another, changes wind and ocean currents and produces volcanoes, all factors that can lead to regional orabout global natural climate change.
volcano eruptions cause cooling effect on the ground. When the volcano explodes, it extends the ash and sulfur oxide into the atmosphere. This material creates a blanket in an atmosphere that is distributed around the world by moving wind. The ash and sulfur oxide blocks sunlight in penetrating the atmosphere and heating the Earth. Without this sunlight, the ground begins to cool down.
It differs from greenhouse gases, such as carbon dioxide, which freely let the sunlight pass through the atmosphere to the Earth's surface, but blocks light from traveling back to space and causes warming effect. Human activities have caused an increase in carbon dioxide emissions and a decrease in Earth's ability to remove carbocxide from the atmosphere.
Combined effects of changes in the ground position on the sun also contribute to natural climate change. Over the course of the year, the Earth will change its tilt, so it is North end towards the sun for about half a year and the south end is toward the sun for the other half, which is upBeling a seasonal climate change. The axis or line on which the Earth leans and rotates is also changing very slightly over time to place some areas of the Earth in a more powerful sunlight than others. In addition, the Earth's orbit is changing all year round, so it is closer to the sun and its heat than others at some points of the year.
Thermohalin circulation in the Earth's oceans, also known as the belt of the ocean conveyor, also affects the natural change in climate. In general, the circulation of thermohaline is deep ocean currents that transmit heat to different parts of the world. This process is largely driven by uneven masses of dense and less dense searching to stabilize it. Changes in this circulation change the way the heat is distributed throughout the country and how much carbon dioxide is able to remove from the atmosphere.
