2. What is Global Warming?
Global Warming is an average increase in the Earth temperature, which causes changes in climate.
Gases in the atmosphere allow sun light to heat the Earth’s surface.
Global Temperatures have increased about 1c since the late 1800s.

3. The effects of global warming are...
*Changes in ecosystems
*Temperature change
*Change in weather patterns.

4. What are greenhouse gases?
S U N
Some Long wave is lost to space
Some Long wave is lost to space
Reflected by Earth’s surface to space.
Solar Energy Absorbed at the surface
Converted into heat causing the emission of longwave radiation
Surface gains more heat and longwave radiation is emitted again
Surface gains more heat and longwave radiation is emitted again

5. These are just a few causes of greenhouse gases!

6. And here is Evynne with how to stop global warming!
