Climate change, specifically global warming, has captured the attention of people worldwide and has inspired more debate and action—personal, political and corporate—than perhaps any other environmental issue in history.

But all of that discussion, along with the mountains of data and conflicting points of view that go with it, sometimes make it hard to really know what’s going on. This guide will help you cut through the rhetoric and confusion and get to the facts.

The Nuts and Bolts of Climate Change

The first step toward learning what can be done to reduce global warming, and how you can help, is to understand the problem.

Greenhouse Gases and the Greenhouse Effect

The greenhouse effect is a natural phenomenon, and many greenhouse gases occur naturally, so why are they cited as problems whenever global warming is discussed?

Current and Future Effects of Climate Change

The effects of global warming are often discussed in future terms, but many of those effects are already under way and having an impact on everything from biodiversity to human health. But it’s not too late. If we act now, most scientists believe we can avoid many of the worst effects of global warming.

    Climate Change and Natural Resources


    Reducing global warming and mitigating its effects will require a combination of enlightened public policy, corporate commitment, and personal action. The good news is that the world’s leading climate scientists have agreed that there is still enough time to address the problem of global warming if we act now, and enough money to get the job done without undermining national economies.

    Climate Change and You

    As a citizen and a consumer, you can influence public policy and business decisions that effect global warming and the environment. You can also make lifestyle choices every day that reduce your contribution to global warming.

    Climate Change and Renewable Energy

    One of the best ways to reduce global warming is to use renewable energy that doesn’t emit greenhouse gases.

    Transportation and Alternative Fuels

    Transportation accounts for 30 percent of all greenhouse gas emissions in the United States—two-thirds of that from automobiles and other vehicles—and many other developed and developing nations face similar challenges.

    Global warming is a complex problem that can only be solved by a worldwide effort involving individuals, businesses, and governments at all levels. Global warming affects everyone. Yet, our perspective on the issue—how we see it and how we choose to address it—may be very different from the views of people from other backgrounds, professions or communities around the world.

    Global Warming: Politics, Government and the Courts
    Governments play an important role in the effort to reduce global warming with public policies and tax incentives that help to promote constructive action by businesses and consumers, and through regulation that can prevent abuses that worsen the problem.

    Global Warming and Business
    Business and industry are often cast as environmental villains, and while it is true that the business community produces more than its share of greenhouse gases and other pollutants, businesses also create many of the innovative technologies and strategies needed to address global warming and other serious environmental issues. Ultimately, businesses respond to the market, and the market is you and me.Global Warming and the Media
    The environment has become a hot topic for the media, with global warming leading the list of subjects. One of the best examples is An Inconvenient Truth, which evolved from a slide show into a documentary film that won two Academy Awards.Global Warming: Science and Skepticism
    Despite widespread scientific consensus about the reality and urgency of global warming and its anticipated effects, there are still people who swear that global warming is a hoax and others who argue that no scientific evidence exists. The arguments of most global warming skeptics are easy to refute if you know the facts.While there are some scientists who legitimately disagree with the majority of their colleagues about global warming, others are skeptics-for-hire, accepting money from companies or organizations that hire them to challenge the scientific consensus in order to create public uncertainty and stall political action that could slow global warming.Global Warming Elsewhere on the Web
