Comment les nuages influencent-ils la température de la Terre - Jasper Kirkby. Reforestation: Impact on Climate. Deforestation is occurring in Earth's forests on a massive scale, often resulting in damage to the quality of the land.

Reforestation: Impact on Climate

Agriculture is the largest global driver of deforestation. Farmers cut forests to provide more room for planting crops or grazing livestock. Many small farmers will each clear a few acres by cutting down trees and burning them in a process known as “slash and burn” agriculture. To provide wood and paper products loggers cut down a large number of trees each year. Wildfires and overgrazing also prevent the growth of young trees. The quickest solution to deforestation would be to simply stop cutting down trees or to manage forest resources.

Reforestation has many positive effects on the environment. Reforestation also impacts climate change. A guide to the energy of the Earth - Joshua M. Sneideman. Energy Literacy: Essential Principles and Fundamental Concepts for Energy Education Want to know more about the seven Energy Principles?

Why aren't we only using solar power? - Alexandros George Charalambides. This TED-Ed Select takes a look at sustainable energy and what we use our energy for.

Why aren't we only using solar power? - Alexandros George Charalambides

The Cloud Appreciation Society Despite the major progress in the use of solar energy during the past years, and the large scale installations mainly of Photovoltaics (PVs) and to a lesser extent of Solar Thermal Power Plants, Solar Renewable Energy Systems (RES) have not yet achieved high penetration in the energy sector compared to the existing fossil fuel power plants. This is mainly due to their dependency on the variability of the sun’s irradiance and in most cases, due to the lack of affordable storage options which leads to the attenuation of the power output of the solar RES. How do tornadoes form? - James Spann. The National Oceanic and Atmospheric Administration (NOAA) has an awesome review of many different types of severe weather from its National Severe Storms Laboratory.

Visit the site and learn more about all the types of extreme weather and more about tornadoes. What kind of severe weather are you most interested in? Have you ever experienced any yourself? Want to know the likelihood of a storm occurring today? NOAA also has a Storm Prediction Center that will give you up to date information. Why the Arctic is climate change's canary in the coal mine - William Chapman. Albedo in Latin means “white,” and is a measure of how much solar energy is reflected back into space from a surface.

Why is this so important in regard to climate change in the Arctic? Visit this site and find out! The National Snow and Ice Data Center has lots more information about albedo, sea ice, and the thermodynamics involved in the growth and melting of sea ice. For the current and historical state of Arctic sea ice, visit The Cryosphere Today. Looking for satellite observations of Arctic change discussed in the lesson? Still a bit confused about positive and negative feedbacks? How tsunamis work - Alex Gendler. If you live near the coast, it couldn't hurt to know what to do in case of a tsunami.

How tsunamis work - Alex Gendler

Do not wait for an official warning. Instead, let the strong shaking in the earth be your warning. After protecting yourself from falling objects, quickly move away from the water and to higher ground. Tsunamis are one of the most catastrophic natural disasters possible. Here's a list of ten of the most destructive tsunamis ever. In this article, we'll look at what causes tsunamis, the physics that drives them and the effects of a tsunami strike. Here's an animation of a tsunami detection system. Recent and Historical Tsunami Events and Relevant Data.

As pointed out by Gunnar Heinsohn, the Roman historian Ammianus Marcellinus (325/330-after 391 A.D.) describes in precise and vivid terms a tsunami which has been dated to have occurred on July 21, 365 A.D. Climate change: Earth's giant game of Tetris - Joss Fong.
