GLOBAL WARMING

The scientific community has reached a strong consensus regarding global climate change. The world is undoubtedly warming. This warming is mostly the result of emmissions of carbon dioxide and other greenhouse gases from human activities including industrial processes, fosil fuel combustion, and changes in land use, such as deforestation. Continuation of historical tendencies of greenhouse gas emissions will result in additional warming over the 12st century, with current projections of a consequences for the world, because it will also mean a sea-level rise that will droughts and floods and threats to biodiversity.

Addressing climate change is no simple task. To protect ourselves, our economy, and our land from the adverse effects of climate change, we must dramatically reduce emissions of carbon dioxide and other greenhouse gases. To achieve this goal we must fundamentally transform the way we organise our global economy. We need to change from fossil fuel use to more efficient and renewablesources of energy. Such a transformation will require society to engage in a common effort, over the near and long-term, to seek out opportunities and design actions to reduce greenhouse gas emissions.

Policy makers must be aware of this danger and goverments should educate the public about the causes and potential consequences of climate change. They should also assist the domestic and international communities in developing practical and effective solutions to this important enviromental challenge.
