GLAS provides continuous light beam observations of Earth. When each light beam reaches Earth, it is reflected back to the satellite. By tracking and recording the amount of time each beam of light takes to return to the satellite, GLAS can be used to calculate many properties of Earth's surface.

Climate Change and Ecosystem

Climate change can alter where species live, how they interact, and the timing of biological events, which could fundamentally transform current ecosystems and food webs. Climate change can overwhelm the capacity of ecosystems to mitigate extreme events and disturbance, such as wildfires, floods, and drought.

2) Climate change is a problem to forests because it can cause damage to the organisms living in the forests or even the wild life, it can cause forest fires, lack of food, etc.

3) "In the Article 'The Glas is Half Full' it mostly talks on survival on Planet Earth and how on the Planet we gain energy by sunlight, and when it started. It also talks about the type of chemicals and oxygen that's very important and that we need, and fossil fuels that can create energy for the Earth. Last but not least, it talks about different areas where sunlight is most needed like forests for the organisms, important chemicals that help develop the energy which makes us have sunlight electronics and other different things that we need."

4) In the article, Climate Change and Ecosystems, it talks about the change of the weather and how it affects natural habitats like forests, also oceans and other places where organisms live. "Changes are expected to alter the makeup and functioning of ecosystems, as well as some of the critical benefits that ecosystems provide to people. Climate change can threaten ecosystems that have already been weakened by other human activities such as pollution, development, and overharvesting." This part of the article talks about the affects, causes, and also the consequences dealing with human activity that put these natural habitats at risk. "Warming of the Earth’s oceans can affect and change the habitat and food supplies for many kinds of marine life—from plankton to polar bears." The natural habitats go through rapid changing so all the other organisms have to adapt or is already adapted to their living condition, it doesn't matter if it's cold, warm, hot, sunny, etc. they have to adapt to whatever it is in their ecosystem with the climate changes.

5) In both article they talk about cause, affect, and consequences dealing with both areas and the living conditions they go through.
