  • Greenhouse effect
  • What will we do to slow this warming? How will we cope with the changes we've already set into motion? While we struggle to figure it all out, the face of the Earth as we know it—coasts, forests, farms and snow-capped mountains—hangs in the balance.

  • Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace. It's becoming clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than in the last 650,000 years.We call the result global warming, but it is causing a set of changes to the Earth's climate, or long-term weather patterns, that varies from place to place.
  • First, sunlight shines onto the Earth's surface, where it is absorbed and then radiates back into the atmosphere as heat. In the atmosphere, “greenhouse” gases trap some of this heat, and the rest escapes into space. The more greenhouse gases are in the atmosphere, the more heat gets trapped.
  • The "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere trap heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse.
  • Aren't temperature changes natural?The average global temperature and concentrations of carbon dioxide (one of the major greenhouse gases) have fluctuated on a cycle of hundreds of thousands of years as the Earth's position relative to the sun has varied. As a result, ice ages have come and gone.
  • Occasionally, other factors briefly influence global temperatures.  Volcanic eruptions, for example, emit particles that temporarily cool the Earth's surface.  But these have no lasting effect beyond a few years. Other cycles, such as El Niño, also work on fairly short and predictable cycles.Now, humans have increased the amount of carbon dioxide in the atmosphere by more than a third since the industrial revolution
  • Why is this a concern?The rapid rise in greenhouse gases is a problem because it is changing the climate faster than some living things may be able to adapt. Also, a new and more unpredictable climate poses unique challenges to all life.
  • As the mercury rises, the climate can change in unexpected ways. In addition to sea levels rising, weather can become more extreme. This means more intense major storms, more rain followed by longer and drier droughts (a challenge for growing crops), changes in the ranges in which plants and animals can live, and loss of water supplies that have historically come from glaciers.

  • Some impacts from increasing temperatures are already happening.Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.Sea level rise became faster over the last century.

      This website says that the planet is warming everywhere, Mercury is is 1 degree Fahrenheit, the effects of rising temperature will be greater in the future.

    The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive polar regions. And the effects of rising temperatures aren't waiting for some far-flung future. They're happening right now.

    This course explores the science of climate change. Students will learn how the climate system works; what factors cause climate to change across different time scales and how those factors interact; how climate has changed in the past; how scientists use models, observations and theory to make predictions about future climate; and the possible consequences of climate change for our planet.

    Global Warming The current cycle of global warming is changing the rhythms of climate that all living things have come to rely upon. What will we do to slow this warming? How will we cope with the changes we've already set into motion?

    "Tunisia. Egypt. Libya. And Now Bahrain. Protests have spread throughout the Middle East like a wild fire -- and you might assume that it's all just a matter of popular sentiment. But if you take a step back, you find that the countries that have seen the most protests also share some deep, structural similarities."

  • Egypt paid a huge price, in terms of lives lost, for the revolution. However, a Brigadier with Cairo's police, told Al Jazeera in an exclusive interview that many lives could have been saved if police personnel had undergone correct training for riot control. The government says 365 people died, but scores of people are still missing.
