Today is Blog Action Day ’09 and almost 7,000 sites around the world are joining together to blog about climate change.
My Green Side is honored to be a part of this event.
According to the Pew Center on Global Climate Change, one of the most significant challenges in addressing global climate change is reducing greenhouse gas (GHG) emissions resulting from the use of coal. Coal use, primarily for the generation of electricity, now accounts for roughly 20 percent of global GHG emissions. Rising energy demand will continue to drive up coal consumption, particularly in countries with large reserves such as the United States, China and India.
Here is a wonderful Q & A courtesy of the Pew Center (from the Kids Page):
Do scientists agree about global warming?
Scientists who study the climate are still arguing about how fast the earth is warming and how much it will warm, but they do agree that the earth is warming and that it will keep warming if we don’t do anything about it.
What is causing global warming?
Scientists agree that the burning of fossil fuels like oil and coal cause greenhouse gases to escape into the air and that these gases are causing most of the warming. Another cause is deforestation (cutting down trees). Trees soak up carbon dioxide, one of the greenhouse gases, from the air.
What is the difference between “global warming” and “climate change?”
“Global warming” refers to the increase of the Earth’s average surface temperature, due to a build-up of greenhouse gases in the atmosphere. “Climate change” is a broader term that refers to long-term changes in climate, including average temperature and precipitation.
What will happen if global warming continues?
There are already some changes happening because of global warming. Sea level is rising and some animals are already moving to new homes. It’s already too late to stop global warming completely.
If the warming gets worse, as scientists expect, there may be some kinds of plants and animals that become extinct (disappear completely) because they can’t move to new homes. There may be more storms and floods. Sea level may rise so much that people have to move away from the coasts. Some areas may become too dry for farming.
What is being done about global warming?
Global warming is a very difficult problem to fix. People are having a hard time agreeing on what to do about it. For example, everyone agrees that wasting energy is a bad thing to do. But some people think that the federal government should make laws about it, while other people think it should be up to each person or business to decide what to do.
Many states and businesses in the United States are not waiting until the federal government decides what to do. They have already started working on the problem.
What can I do about global warming?
You don’t have to wait until you are grown to do something about global warming. Scientists agree that the burning of fossil fuels is causing global warming. Since these fuels are burned for energy, and everyone uses energy, everyone can help stop global warming just by using less energy.
Think about the things you do each day that use energy. The lights in your house use electricity. The TV and computer use electricity. The washing machine, dishwasher and dryer all use gas or electricity. Every time you ride in your car, it uses gasoline.
There are some simple things that you can do to help stop global warming:
- Wait until you have a lot of clothes to wash before using the washing machine. Don’t use the machine for one item just because it’s your favorite shirt.
- Turn off the lights when you leave a room.
- Turn off your computer or the TV when you’re not using it. Unplug chargers when not in use.
- Close the blinds on a hot day if the sun is shining in. Dress lightly instead of turning up the air conditioning. Or use a fan.
- Dress warmly inside your house when it’s cold, instead of turning up the heat.
- Bike or walk short distances instead of asking for a ride in a car.
- Plant a tree.
- Take shorter showers. Heating water uses energy.
