Climate Change

A few quick references to show how we know climate change is happening


The greenhouse effect is essential to life on Earth, but human-made emissions in the atmosphere are trapping and slowing heat loss to space.

Five key greenhouse gases are carbon dioxide, nitrous oxide, methane, chlorofluorocarbons, and water vapor.

While the Sun has played a role in past climate changes, the evidence shows the current warming cannot be explained by the Sun.

This is a great infogrphic to show changes in global temperature over the last 22 000 years. I can’t upload the whole thing as it is a png file and they don’t upload. I’m working on it! For now enjoy the original.

The whole thing is shown at the bottom of this post! It was too long to have at the top but it is amazing.



Here’s some CO2 data for students to practice graph plotting

What’s our Countries temperature changes?

Now you can look at the drop in Biodiversity with climate change

Effects of different temperature rises

Videos showing the effects of different temperature increases

1-2oC warmer

2oC warmer

What happens when the global temperature rises by 1 to 2 degrees Celsius?

2-3 oC warmer

What happens when the global temperature rises by 2 to 3 degrees Celsius?

3oC warmer

3-4 oC warmer

4 oC warmer

4-6oC warmer



No point showing the bad side if I can’t show you some solutions

or sign up with the World Health Organisation (WHO) App

I’ve put this at the bottom as some of you wouldn’t make it this far. Note, this is not to scale in the last few centuries The scale increases at 1500 AD and then again at 2000. This last section should take up just a tiny space!

For the Teachers
