What if we could pull carbon dioxide out of the atmosphere in order to stop climate change? Learn how researchers are developing ways to do this.
Resource Type: Information
How do we catch carbon? The possibility of capturing carbon dioxide greenhouse gas (CO2) has become an increasingly attractive idea, especially as people realize that it is unlikely we will stop using fossil fuels entirely in the next hundred years.
Resource Type: Information
How much carbon dioxide do you send into the atmosphere? Anytime you do something that requires fossil fuels - like riding in a car, flying in a plane, buying something, eating something, or even just watching TV - you emit carbon dioxide into the atmosphere.
Resource Type: Information
Use a simple climate model to peek into the future. You suggest the rate that you think humans will release carbon dioxide into the atmosphere in the future and the model calculates how that would affect temperature.
Resource Type: Information
Blocking some solar radiation from getting to Earth could involve sending gases or particles into the atmosphere. It could also include methods like making clouds or the Earth’s surface brighter so that they reflect sunlight back out to space. Methods like these could help slow climate change, but there could be risks.
Resource Type: Information
There are two main ways to stop the amount of greenhouse gases from increasing: we can stop adding them to the air, and we can increase the Earth’s ability to pull them out of the air. Doing both will help reduce the amount of greenhouse gases in the atmosphere.
Resource Type: Information
We caused the problem by increasing the amount of greenhouse gases in the atmosphere, but we have the ability to keep the amount of warming low enough that it is survivable. Communities and nations around the world are taking action to solve climate change.
Resource Type: Information
When warm and cold air collide, warm air is pushed up and can form clouds.
Resource Type: Information
Clouds are given different names based on their shape and their height in the sky. Learn about each cloud type and how they are grouped.
Resource Type: Information
When wind blows across a mountain range, air rises, then cools and clouds form.
