One problem scientists have run across in trying to prove global warming is the limited timeframe they have to work with. We only have temperature data from the past 150 years, which is a very short period in global terms. Many people are skeptical of climate change because of this limited frame of reference. However, data does show that the earth’s average temperate has increased about 1°F over the past century. Also, the past 15 years have been the warmest in our recorded history.

Global warming is thought to be caused by a process called the “greenhouse effect.” T

he earth’s weather and climate are determined by energy released by the sun. In turn, the earth radiates energy back into space. Some of this energy, however, is trapped in the atmosphere by gases. Thus, these gases are called “greenhouse gases” because they act like the glass panels of a greenhouse. Greenhouse gases are actually necessary for life on earth; without them, our planet would be much too cold. However, a problem arises when we have too many of them in our atmosphere. The gases accumulate and disrupt the natural greenhouse process.

If our own president isn’t willing to prevent global warming, we will have to take this matter into our own hands for the time being. There are many ways that each of us can help prevent global warming in our everyday lives. They include buying Energy Star compliant products, carpooling, composting, and recycling. It may not seem like much, but together we can help to maintain a healthy, happy pla
