'Time for a paradigm shift in awareness of our own cause and effect on the environment. Most people are currently oblivious to the sum total of their seeming little actions in the context of the big picture.'
By the end of the century, average temperatures will rise regardless of our emissions output: In the US, 4.5 degrees F (2°C) in a low emissions scenario, as seen on the left, versus 8 degrees F (4°C) in a high emissions scenario, shown on the right. Image: NASA.
Climate Change Online Lab - Lesson Plan - In this activity, students will learn about Earth’s climate vital signs. They will use NASA’s Climate Change website to learn about the factors that scientists use to understand changes in our climate.
