Climate change explained...

Introduction
Climate change is a problem that is affecting people and the environment. EPA The Basic Information page provides basic information for someone new to the issue of climate change, including introductions to climate change science, U S policy on climate change, emissions, effects, and what you can do. Climate change is already affecting our lives and the places we live, and has the potential to dramatically impact the lives of future generations. Scientists are certain that human activities are changing the composition of the atmosphere, and that increasing the concentration of greenhouse gases will change the planet's climate. Somebody has to double check this!

Description
Greater energy efficiency and new technologies hold promise for reducing greenhouse gases and solving this global challenge. In common usage, "global warming" often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities. Greenhouse gases are necessary to life as we know it, because they keep the planet's surface warmer than it otherwise would be. Water is affecting the temperature level, changes in precipitation patterns, rising sea levels, and more frequent weather-related disasters pose risks for agriculture, food, and water supplies. Arctic Council told it is failing to safeguard the region, while EU accused of 'panic reactions' over deep-water drilling ban.

No matter how aggressively heat-trapping emissions are reduced, some amount of climate change and resulting impacts will continue Consequently, there is a need for adaptation. Climate change may result from: natural factors, such as changes in the sun's intensity or slow changes in the Earth's orbit around the sun; natural processes within the climate system e g changes in ocean circulation ; human activities that change the atmosphere's composition e g through burning fossil fuels and the land surface e g deforestation, reforestation, urbanization, desertification, etc .

Conclusion
The EPA Climate Change site provides comprehensive information on the issue of climate change and global warming in a way that is accessible and meaningful to all parts of society - communities, individuals, business, states and localities, and governments. New Scientist's guide to climate change, global warming and greenhouse gases provides a comprehensive source of information on the matter. It is a race between mankind and natural phenomena. Who will be the one prevailing, no one can tell for sure! We must stay alert.
