Aim: To look at the causes of climate change and how to prevent it.
As you watch the video answer these questions:
What is our greatest threat in thousands of years?
- Climate Change
How do we see climate change affecting the globe?
- Floods
- Winds
- Storms
- Heat Waves
What is needed to change history?
- Take Action
Is climate change a man made disaster?
- Yes, because we are burning fossil fuels
Dramatic action must be made in the next ten years to change it?
Why is our climate changing?
- Because of one simple fact = Our world is getting hotter
What is causing the warming trend of the climate?
- Human Activities
What is the main problem?
- We are all using energy all the time and in the industrial world that energy is almost entirely fossil fuels
What are examples of these?
Burning fossil fuels releases what gas?
- Carbon Dioxide
How much hotter now is our world?
- Over 400
What do we call this global warming?
How is this affecting creatures / animals like bats?
- The heat
What percentage of species are near extinction?
- Some animals are not use to the climate change changing
How could this effect the world ecosystems?
- 8 Percent
What global change was seen and recording breaking last year?
- Wildfire
How is climate change affecting our weather systems?
The amount of water vapor in the atmosphere has in fact increased due to human- caused warming
- This extra moisture is available to storm systems & heavier rainfalls.
1. Evaporating of the oceans
2. When there is no moisture in the air, your gonna get more rain
3. With a degree Celsius of warming, there is no moisture
What is another effect of climate change?
- As the climate change warms, it changes the nature of global rainfall, evaporation, snow,stream flow and other factors that affect water supply and quality.
What will happen if the ice melts in Antarctica and the Arctic?
- If the Antarctic ice melted, sea levels around the world rise above 61 meters
(200 Feet). But the average temperature in Antarctica is - 37 Celsius, so the ice there is in no danger of melting.
How does this affect people?
What other things affect oceans change?
- Due to climate change, as the ocean gets warmer, this too has an effect on the seafloor.
What does to much heat do to coral?
- Rising ocean temperatures can kill corals. Humans pumping more and more greenhouse gases into the atmosphere and that is trapping excess heat and causing the surface of the planet to warm.
Why did some industries not want to stop burning fossil fuels?

Investigation
You can decide on how you would like to do this investigation. Your presentation could be on the blog, slides, or Powerpoint.
Write a definition, upload an image and list where these fossil fuels are mined.
- Coal
- Oil
- Natural Gas
- Coal is a hard rock which can be burned as a solid fossil fuel
- A viscous liquid derived from petroleum, especially for use as fuel or lubricant.
- Flammable gas, consisting largely of methane and other hydrocarbons, occurring naturally underground
Write a paragraph and upload an image about each of these renewable energy.
Solar energy is radiant light and heat from the sun, energy is the ability to do work, and "solar" is a Latin word for the sun. So, we can define solar energy as energy obtained from the sun, we can put this energy to work for us in many ways, from heating water and living spaces within our homes to generating electrical energy. Wind energy is an electrical energy obtained fro m harnessing the wind with windmills or wind turbines. Wave energy, aka ocean energy or sea wave energy, is energy harnessed from the ocean or sea waves... Exactly, waves are created by the wind that passes over the oceans surface. Flowing water creates, energy that can be captured and turned into electricity, this is called hydroelectric power or hydro power. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir.
China is the world leader in wind power generation
The National Energy Board of Canada expects that by 2040, solar power will generate 1.2% of the country's electricity while wind will provide 9.5%.
= Hydroelectricity is the largest renewable energy source in Canada, approximately 60 percent of Canada's electricity generation.
Write a 6 sentence reflection about what you have learnt about Climate Change and how it is going to affect us.
In science Hurumanu we watched a facts video about climate change and while watching the video, we had to try and answer some questions based on climate change. I learnt some new things about climate change that i didn't know before. First of all I learnt that our climate is changing, simply because our world is getting hotter. I also learnt that the main problem is that we are all using energy all the time and in the industrial world that energy is almost entirely fossil fuels. I think climate change is going to affect peoples lives and health which I hope not, the reason why I think this is because according to World Health Organization, Air pollution kills an estimated 7 million people worldwide every year.
