Weather Climate

From wind and rain to tornadoes and hurricanes, weather is a powerful force in our world. Discover how weather changes the world we live in and how scientists learn about its impact on our daily lives.

Look up! When you look to the sky, do you wonder why the sun is so bright or why the clouds are white or why the sky is blue? Then Weather for Dummies is your resource to fuel your curiosity about the weather. It takes you on an exciting journey through the Earth's atmosphere and the ways it behaves. You'll get an overview of rain, sun, clouds, storms, and other phenomena.

An astonishing transformation over the last 20,000 years has seen our planet changed from a frigid wasteland into the temperate world within which our civilization has grown and thrived. This dynamic episode in our planet's history, right at the close of the Ice Age, saw not only a huge temperature hike but also the Earth's crust bouncing and bending in response to the melting of the great ice sheets and the filling of the ocean basins - dramatic geophysical events that triggered earthquakes, spawned tsunamis, and provoked a series of eruptions from the world's volcanoes.

In its 2001 report on global climate, the Intergovernmental Panel on Climate Change of the United Nations prominently featured the "Hockey Stick", a chart showing global temperature data over the past 1,000 years. The Hockey Stick demonstrated that temperature had risen with the increase in industrialization and use of fossil fuels. The inescapable conclusion was that worldwide human activity since the industrial age had raised CO2 levels, trapping greenhouse gases in the atmosphere and warming the planet.

Climate change is today's news, but it isn't a new phenomenon. Centuries-long cycles of heating and cooling are well documented for Europe and the North Atlantic. These variations in climate, including the Medieval Warm Period (MWP), AD 900 to 1300, and the early centuries of the Little Ice Age (LIA), AD 1300 to 1600, had a substantial impact on the cultural history of Europe.

Climate change is with us, and we need to think about the next big disturbing idea - the potentially disastrous consequences of massive numbers of environmental refugees at large on the planet. In 2020, the United Nations projects that we will have 50 million environmental refugees mostly from Africa, Asia, and Latin America. How will people be relocated and settled? Is it possible to offer environmental refugees temporary or permanent asylum? Will these refugees have any collective rights in the new areas they inhabit?

Ever wonder which states are the cloudiest? Or what city gets the most snow? Climate maps can tell you. They show average weather conditions - in your neighborhood, around the world, or even on Mars! But how do you read a climate map? And how are these maps made? Listen to learn the details!

The fourth book in our Ask the Experts series, The Environment tackles questions about the world around us. In this book, our experts field queries on the weather, natural disasters, natural resources, climate change, and unusual phenomena.
