The document discusses global warming and its causes. It states that global warming is an increase in the average temperature of the Earth's atmosphere and oceans, with surface temperatures rising 0.74°C over the past century. The primary cause of global warming is carbon dioxide emissions from the burning of fossil fuels. Increased greenhouse gases like CO2 trap more heat in the atmosphere, enhancing the natural greenhouse effect and amplifying global warming. Effects of global warming include rising sea levels and temperatures, melting ice caps, and more extreme weather events. Solutions proposed are reducing CO2 emissions through energy efficiency and renewable energy.

6. Greenhouse Gases

7. These greenhouse gases reabsorb heat reflected from the Earth's surface, thus trapping the heat in our atmosphere. This natural process is essential for life on Earth because it plays an important role in regulating the Earth's temperature. iel_triward09@yahoo.com iamsuperielherrera@yahoo.com

9. The greenhouse effect is a natural warming process. Carbon dioxide (CO2) and certain other gases are always present in the atmosphere. These gases create a warming effect that has some similarity to the warming inside a greenhouse, hence the name “greenhouse effect.’’iel_triward09@yahoo.com iamsuperielherrera@yahoo.com

11. Increasing the amount of greenhouse gases intensifies the greenhouse effect. Higher concentrations of CO2 and other greenhouse gases trap more infrared energy in the atmosphere than occurs naturally. The additional heat further warms the atmosphere and Earth’s surface.iel_triward09@yahoo.com iamsuperielherrera@yahoo.com

14. The primary cause of global warming is Carbon Dioxide emissions. CO2 is being pumped into our atmosphere at an insane pace; 8 billion tons of CO2 entered the air last year. Of course some of this is due to natural activity such as volcanic eruptions and people breathing.iel_triward09@yahoo.com iamsuperielherrera@yahoo.com

17. The first several of these links is an over abundance of solar radiation absorbing gases and other particles floating about in our atmosphere.

18. The next grouping of events concerns what happens when the small percentage of increased heat on our planet’s surface and in our air begins to effect long standing conditions.iel_triward09@yahoo.com iamsuperielherrera@yahoo.com

20. The rise in temperature around the Earth over the last fifty years is only around on-degree on average. If we are just raising the temperature a little bit why does it matter? Global warming is melting the North and South poles; it is creating floods in some areas and deserts in others. iel_triward09@yahoo.com iamsuperielherrera@yahoo.com

22. Global warming is also believed to be responsible for recent changes in our weather. There are more hurricanes in the northern hemisphere every year than ever before. And these hurricanes are more powerful than the ones from 50 years ago. Rising oceans, increased rainfall, loss of fresh water and dozens of other problems are on the rise and the cause is global warming.iel_triward09@yahoo.com iamsuperielherrera@yahoo.com

24. Rise of sea levels by at least 25 meters (82 feet) by the year 2100.iel_triward09@yahoo.com iamsuperielherrera@yahoo.com

26. Install a programmable thermostat

27. Move your thermostat down 2° in winter and up 2° in summe

28. Clean or replace filters on your furnace and air conditione

29. Choose energy efficient appliances when making new purchases iel_triward09@yahoo.com iamsuperielherrera@yahoo.com
