THE CAUSE OF GLOBAL WARMING
by: Juan Estrada
What is Global Warming?
My opinion on Global Warming Cause
-Why it's man made: many factories let out green house gasses, green house gases are gases that absorb infrared radiation, like carbon dioxide. This is bad for earth because these gases are trapping heat from escaping that the sun brings. So humans are basically enhancing the green house effect and making it hotter. This could also harm us because we are not used to warmer climates. So it is arguable that humans are heating up the earth by the greenhouse effect.
-Why it's a natural temperature change: some global temperature changes are due to natural causes. One example of them would be volcanic eruptions. They emit particles that temporarily cool the earths surface. But these don't have a long lasting effect. But one that does is the effect of "El Niño". El Niño is a temporarily change in temperature in the Pacific Ocean, it's around the equator. El Niño effect warms up the ocean a few degrees Celsius and it also moves the thunderstorms that happen in the equator eastward. These make a huge difference in the earths atmosphere.
