Hurumanu - Science - Climate Change

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?

 1. Sea level will rise, islands have a high risk of sinking and banishing the water.
2. Droughts, especially in tropical countries.
3.Typhoons and hurricanes might get stronger.

4. And with the typhoons, there will be a high possibility that we'll get landslides that will block people's way, especially when hills, mountains and roads are next to each other.  

5.Ice melting, with the hot weather the ice from the north pole, is melting.

What is needed to change history? Urgent Actions.  We could've changed the way we recycle garbages, the way people handle garbage, it's not about garbage, it's also about nature too. People could've planted seeds after cutting trees before.

Is climate change a man-made disaster? Yes, it is because of what the people did, they made something/create/invent something that helped people’s lives to get better, like cars,factories that release smoke - to name a few, but is doing harm to the world.

Dramatic action must be made in the next __ years to change it? Ten years

Why is our climate changing? Because of the people's doing

What is causing the warming trend of the climate? The people and the people’s inventions, cars and factories for example, that will cause air   causing acid rains and the acid rain will go to the sea that will kill thousands of fish, that will kill the sea life, people won’t have anything to eat and if people did catch a fish that has been poisoned by the acid rain, they'll get sick and might even die.

What is the main problem?  The way we use things, the way we do things, the way we treat nature and environment. Some people think that they're actually making a change to the world but it's doing the opposite. Because our actions affects how the world is changing

What are examples of these? Cars and factories

Burning fossil fuels releases what gas? Carbon Dioxide

How much hotter now is our world? The Earth’s temperature increased by about 1-degree Celsius

What do we call this global warming? Climate Change

How is this affecting creatures / animals like bats? Even the animals that can handle the heat, like bats, for example, die because of the hot temperature. Even their way of getting cool is not enough to handle the heat. They still die, about thousands of bat have died.

What percentage of species are near extinction? 88%

How could this affect the world ecosystems? A desert, for example, the temperature will increase causing dessert animals to die because even though they’re desert animals and insects, They won’t be up for that extreme temperature and desert plants will overdry

What global change was seen and recording breaking last year? Wildfires, when redwoods burn it and it’s near a road, it will block a people’s way, it’d be more dangerous especially when someone’s going through the road, the burning tree might fall on them

How is climate change affecting our weather systems?
1. You get more rain (the water from the ocean evaporates and the clouds are getting moisture, with a lot of moisture on the clouds, it will rain really hard)
2. Superstorms/typhoons and flooding
3.  It’s way hotter than it was before (dryer weather)

What is another effect of climate change? Ice melting/fusion

What will happen if the ice melts in Antarctica and the Arctic? It’s losing 3 times of ice than it was 25 years ago, the glaciers that melt goes in the ocean causing the sea level to rise.

How does this affect people? They’re losing homes, the wetlands of Louisiana is disappearing, it protects Southern Louisiana but now it’s disappearing underwater.

What other things affect oceans change? The sea life, habitats/corals are getting destroyed/dying, fishes won’t have anything to live in.

What does to much heat do to coral? Because of the rising temperature of the ocean, it damages the corals, the sea life, it causes the algae from the corals to banish, without algae corals dies.

Why did some industries not want to stop burning fossil fuels? Because it’s the way to get energy, to produce energy
