The Earth’s atmosphere is complex and amazing. You couldn’t live without it! But human activity can have a negative impact on all parts of the environment, including the atmosphere.

The ozone hole and climate change are important examples of how human activity can have negative impacts on the atmosphere. Both remain major concerns. However, scientists recently discovered that the ozone hole over Antarcticahas begun to improve. And in 2016, the Paris Agreement on climate change marked further efforts to reduce global warming.

To find out more about the ozone hole, climate change, and what it all means for you, check out these CurioCity resources.

1) Ozone Update

In the 1970s, the Earth’s ozone layer came under attack. More than 30 years later, the ozone layer’s future is looking a lot brighter!

2) How and Why Is the Ozone Layer Damaged?

Over time, there has been a net depletion of ozone in the atmosphere. As a result, there is a higher risk of exposure to harmful UV radiation from the sun. Only a big international ban on CFCs prevented further destruction of ozone.

3) Keeping Cool Without Killing the Planet—Speaking of Chemistry

This video looks at the pros and cons of new, more environmentally-friendly alternatives to refrigeration. (3:19 min.)

4) Oxygen Is for Breathing, but Ozone Can Harm Your Lungs

Who knew an otherwise helpful molecule could do so much damage when it’s in the wrong place!

5) Climate Change 101

Bill Nye narrates this short film on the basics of climate change.

6) The Carbon Problem: From Fossil Fuels to Greenhouse Gases

The average Canadian produces the equivalent of about 20.3 tonnes of carbon dioxide per year, or about the weight of four adult African elephants!

7) Cows or Cars: Which One Has the Biggest Impact on Climate Change?

Animal agriculture is a big source of methane emissions. That’s right—this powerful greenhouse gas is being produced by cows!

8) Misconceptions About Climate Change by Veritasium

When discussing scientific results it is common that not everyone agrees, and it is therefore important to be able to evaluate scientific evidence yourself. What YOU think? Should we be concerned about global warming?

9) Paris Climate Agreement to Be Signed Starting on Earth Day (April 22, 2016)

Did you watch the news in December 2015? If so, you probably heard about a big climate change conference that took place in Paris, France.

10) Alternative Energy Trends

Alternative energy technologies promise to revolutionize the way you think about energy generation, clean technology, and combating climate change.
