The nations were angry; and your wrath has come. The time has come for judging the dead, and for rewarding your servants the prophets and your saints and those who reverence your name, both small and great — and for destroying those who destroy the earth.
I believe the term “global warming” is familiar to you. But maybe we don’t understand enough to know why and how it happens and what we can do to reduce it. Today, we’ll look at the cause and effects. Next week we’ll see how to reduce it.
Global warming is the rise in the average temperature of earth’s atmosphere and oceans. It happens when green house gases are released into the atmosphere. Water vapor, carbon dioxide (CO2) and methane (CH4) are some of them. A greenhouse gas is a gas that traps heat in the earth’s atmosphere.
Burning fossil fuels causes pollution that causes global warming. Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they release a green house gas called CO2. Mining coal and oil allows methane to escape. Methane is naturally in the ground. When you dig up the fossil fuels you dig up the methane as well.
What about the population? More people means more food, and more agriculture. Another source of methane is manure. More people means more cars, and more cars means more pollution. More people also means more CO2 because we breathe out CO2. What makes the problem worse is the trees that convert our CO2 are being destroyed.
Some of the effects of global temperature increase are a rise in sea levels; extreme weather including heat wave, droughts and heavy rainfall; species extinctions; decreasing crop yields and the loss habitat. (Adapted from en.wikipedia.org, library.thinkquest.org)
“Lord, You are the Creator of the universe. We thank you for the planet we live in. Help us to care and be responsible for our activities so that it may not harm the earth. In Jesus I pray. Amen.”
