Hello questions about global warming!?

Mercedez Trabue: 1 The cause of Global Warming is a natural cycle of warming and cooling of the earth for millions of years. The latest warming cycle appears to have started at the last Ice Age.2. Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface, some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time, the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back into space, leaving the temperature of the Earth’s surface roughly constant. Many gases exhibit these “greenhouse” properties. For example water vapor, carbon dioxide, methane, and nitrous oxide.3. Global warming is part of a natural cycle that will cause greening in the colder regions. Humans! can live more comfortably in higher latitudes. However the temerature average is increasing 1 degree every 100 years. 4. Humans will have no effect to slow global warming. Global warming and global cooling are natural cycles that have occured many times over millions of years....Show more
