Short Essay On Global Warming In Simple English
As the Earth's surface temperature becomes hotter the sea level becomes higher.This is partly because water expands when it gets warmer. Strong storms may become more likely and farming may not make as much food. The changes from one area to another are not well known.One of the most famous warm times was the Medieval Warm Period and one of the most famous cool times was the Little Ice Age.Other proxy measurements like the temperature measured in deep holes mostly agree with the tree rings.One way is to cut into a tree and measure how far apart the growth rings are.Trees that live a long time can give us an idea of how temperature and rain changed while it was alive.
As a prediction, many cities are soon to be partially submerged in the ocean.
Many scientists say that in the next 100–200 years, temperatures might be up to 6 °C (11 °F) higher than they were before the effects of global warming were discovered.
Most noticeable changes by this increase in temperature is the melting of ice caps all around the world.
When people use fossil fuels like coal and oil, this adds carbon dioxide in the air.
When people cut down many trees (deforestation), this means less carbon dioxide is taken out of the atmosphere by those plants.
