Fifteen of the 16 warmest years ever recorded have occurred since 2001. And it's not stopping on its own. But there are things you can do right now to fight this.
1. Change your lightbulbs - really.
What are the five lights you use the most in your house? Identify them and replace their bulbs with bulbs that have the Energy Star label from the U.S. Environmental Protection Agency (EPA). Doing this can not only help you save $70 a year on energy bills; the bulbs also use about 75 percent less energy and last 10 to 50 times longer.
When you need a new appliance, choose a product that also has the Energy Star label. According to the EPA, products that have earned the Energy Star label "can reduce greenhouse gas emissions by about 130,000 pounds and save you $11,000 on energy bills" over a lifetime.
2. Go meatless one day (or more) a week.
Big agriculture industries, like meat and dairy, emit more greenhouse gases than all the world's transportation combined. Producing beef, lamb and cheese creates some of the highest amounts of greenhouse gas emissions, so cutting down on demand will help.
