Interactive Timeline of the Universe: The Big Bang, Formation of Earth, and Evolution of Life

Some time ago I came across a very nicely done Flash animation showing how the universe and Earth have developed to this point:

The site features a timeline with a slider you can drag. It starts at the big bang, an estimated 13.7 billion years ago. Once the solar system forms some five billion years ago, it focuses on Earth. Since the most interesting things, from a human perspective, have happened recently, there are a series of supplemental sliders to focus on the most recent portion of each timeline. With simple animations, it’s a nice, easy way to visualize the history of our planet, and see just where our little story fits in.

Climate Change Affects the Whole World

Many people in developed nations like the United States understand that global warming (anthropogenic climate change) is a problem, but don’t appreciate how it will affect them. There is sometime a perception that poor areas in the tropics will face flooding and disease, but that it is not a significant matter for developed nations.

However, global warming will cause (and is causing) effects worldwide. A few may be positive, but they are grossly outweighed by the negative effects. The United Nations Intergovernmental Panel on Climate Change (IPCC, recent Nobel Peace Prize winner) has been working on its Fourth Assessment Report, and recently released the Working Group II (“Climate Change Impacts, Adaption, and Vulnerability”) portion of it. It details the predicted effects of climate change for each continent over the next century.

It’s a thorough report, but daunting for the casual reader. However, Time magazine has created a great (Flash-based) interactive graphic simplifying and summarizing the predictions:

It’s great to see efforts in making this information quick and easy to grasp.
