When the sun is at its solar maximum, this means that...

• there are less sunspots on the sun.

• more sunspots on the sun.

• more hurricanes on Earth.

• the sun is closer to the Earth.

How will the greenhouse effect (GHE) be modeled in our lab?

• a screen with glitter was used to block light

• carbon dioxide gas was released by mixing baking soda and vinegar in a "volcano"

• two, 2-liter bottles with sand, thermometers and plastic wrap

• a box with an electric "candle" inside and a peephole to see inside

Evidence for past climate change going back 420,000 years can be seen by examining...
