Stop global warming
Save time and stop global warming
Throughout its long history, Earth has warmed and cooled time and again. Climate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or surface changed, or when the Sun’s energy varied. But in the past century, another force has started to influence Earth’s climate: humanity
How does this warming compare to previous changes in Earth’s climate? How can we be certain that human-released greenhouse gases are causing the warming? How much more will the Earth warm? How will Earth respond? Answering these questions is perhaps the most significant scientific challenge of our time.
Save energy now and stop global warming
Take steps to reduce your energy use, improve efficiency and help end global warming. The biggest cause of global warming is the carbon dioxide released when fossil fuels -- such as oil and coal -- are burned for energy. So when you save energy, you fight global warming and save money, too.
