 Global warming:
Global warming isn't just about things getting hotter -- other changes can occur, including stormier, drier and even, in some instances, colder conditions.
Some effects,
10. Rising Sea Level
9. Shrinking Glaciers
8. Heat Waves
7. Storms and Floods
6. Drought
5. Disease
4. Economic Consequences
3. Conflicts and War
2. Loss of Biodiversity
1. Destruction of Ecosystems


What we have to do immediately:

• Be well informed about global warming. Global warming already disrupts millions of lives daily in the forms of destructive weather patterns and loss of habitat.Being educated on the subject is the first important step to taking action. On a personal level, you'll be more apt to change your lifestyle if you know the truth; on a political level, you'll be better able to inform others and inspire change if you study the issue first.
• Use compact fluorescent or LED bulbs. Replace three frequently used light bulbs with compact fluorescent bulbs and save 300 lbs. of carbon dioxide and US$60 per year. A standard compact fluorescent bulb will save around one third of a tonne of greenhouse gas, along with the cost of six or more incandescent globes.
• Buy locally to reduce the energy required to transport your goods.[8] The consumable products that we all purchase represent more than half of the average family's carbon footprint.
• Try eat both vegetables and meat that came from small farms, rather than large industrial farms, which use environmentally harmful practices.
• Less packaging could reduce your garbage significantly, saving 1,200 pounds of carbon dioxide and $1,000 per year.
• Decide whether something is really worth printing out before pressing "print." Leave a signature at the bottom of your e-mails reminding the reader to think twice before printing the e-mail.
• Make the most of scrap paper for shopping lists, notes, scrapbooks, telephone messages, taking notes in class, etc. Recycle your paper only when it has been thoroughly used up!
• Keep your water heater insulated to save up to 1,000 lbs. of carbon dioxide and US$40 per year.
•  Inefficient appliances (such as refrigerators, washing machines and air conditioners) waste energy. Save hundreds of pounds of carbon dioxide and hundreds of dollars per year by replacing them (and having your old appliance recycled or disposed of properly).
• Many countries have "energy star" ratings on new appliances that allow you to assess the energy usage of the appliance. Check online before you go shopping to save time or at least check the seals on your fridge or freezer and replace them if they show signs of wear.
• Even when electronic devices are turned off, they use energy. Save over 1,000 lbs of carbon dioxide and US$256 per year by unplugging them or switching them off at the wall using a power surge-protector
• Use public transportation. Taking the bus, the train, the subway or other forms of public transportation lessens the load on the roads and reduces one's individual greenhouse gas emissions by an average of 1600 pounds per year.
• Keep your car tires adequately inflated.Buy a fuel efficient car.Change your air filter. Check your car's air filter monthly. Save 800 pounds of carbon dioxide and US$130 per year.
