Global warming is not a 20th century phenomenon. With so much written and reported about global warming, sometimes it is not easy to discover which is just part of scientific scare tactics and which is fact. Here are a few details about global warming that might help:
Global warming is actually the increase in the temperatures of the Planet’s atmosphere, land masses and oceans. The Earth’s surface temperature is at a mean of 59F and over the last hundred years, this amount has climbed to about 1F.
Global warming has and will constantly appear naturally. Is due to the truth that practices and human activities have contributed to its occurrence and severity why it’s become this type of matter in our lifetime. With the advent of industrialization and careless environmental practices, we’ve caused the rise in the typical global temperatures by giving negatively to the greenhouse effect.
This began about 240 years past, when the Industrial Revolution came to be. As increasingly more fossil fuels in the type of oil were mined and burned, gases as the by-product of this process started to be released in the atmosphere. Now, it’s estimated that the burning of these fossil fuels causes 75% of the increase in the carbon dioxide content of the Planet’s atmosphere.
Gases occur in the Earth’s atmosphere and act both to safeguard and retain heat. Of these, water vapor is abundant greenhouse gas and the dominant.
Global warming and the greenhouse effect will not be the same thing. The greenhouse effect refers to a natural process occurring in the Earth’s atmosphere. Whether this process is disrupted, then it might bring about global warming.
Heat is bounced back to the atmosphere where these gases contain the heat and keep it there to warm the planet, as the sun’s rays reach the Earth. That is an important natural process and allows life forms to prosper and endure. Problems only occur when these gases multiply and accumulation, featuring heat too efficiently and hence warming the Planet’s atmosphere.
As the Earth’s average temperature rises, effects in sea water amount and its landmasses become apparent. Polar ice caps melt down together with glaciers, contributing to higher and warmer sea amounts. By the end of the century, it’s estimated that sea levels can rise to a high of around 40 inches if global warming continues unabated.
