"Journaling provides a challenge for a student to produce accurate notes that are meaningful and will always serve to be a personal resource of dependable information. With my age group it utilizes shapes and symbols for each child to easily describe what they are observing. Not only am I able to get a child to begin to understand the importance of their observations, but they are able to take all of their senses and direct their energy to focus."
NASA found a way to visualize the most important process behind global warming
Each year, the world's cars, trucks, power plants, and factories emit billions of tons of extra carbon dioxide into the atmosphere. But where does it all go?
This mesmerizing new animation from NASA simulates a year in the life of all the carbon dioxide — the main gas responsible for global warming — in the atmosphere. The data is from 2006 and yes, it looks like a lava lamp:
More precisely, what this video shows is concentrations of carbon dioxide, ranging from 375 parts per million (in blue) to 385 ppm (in red) up to 395 ppm (in pink). It also shows carbon monoxide in white.
As you can see, carbon dioxide spreads fairly rapidly around the world. That's a key reason why global warming can't be solved by just a few countries acting alone. Emissions from one region don't just affect that region. Carbon-dioxide emissions from the eastern United States get picked up by westerly winds and are carried quickly across the Atlantic. Emissions in China travel far and wide.
As that extra carbon dioxide mixes in the atmosphere, it traps extra heat on the Earth's surface and warms up the planet. On the whole, carbon-dioxide concentrations in the atmosphere have risen from 270 parts per million before the Industrial Revolution to nearly 400 ppm today, largely because we've been burning fossil fuels. As that number keeps rising, it will raise surface temperatures, melt land ice, hike sea levels, and bring all sorts of other changes to Earth's climate.
