On Wednesday the 13th of December we had our Earth Expo. This is were a few weeks ago we picked a topic on the Earth. We had already studied Rotation and Revolution and the layers of the Earth. Our topic had to have to do with something that relates with the Earth. I did Climate Change and Global Warming. And no, I did not do to topics. They relate to each other.
For showing my presentation I did, a poster, an iMovie and an experiment. My mum came. I set up a little sheet that everyone could sign their name or write feedback or comments. I got lots of names! And lots of AWESOME Feedback and comments. Some of the comments were love it! And great job! That made me feel really happy. Mum put a comment on too! My teacher gave me an award for the “very high standard of work on your inquiry project” (THANKS MRS WALKER!!!) You may not know a lot about Climate Change and Global Warming so you can read and watch all my stuff!
CLIMATE CHANGE/ GLOBAL WARMING
What is climate?
Climate is the weather conditions in an area or over long period.
Climate is the temperature in general.
For example, in Gisborne, the warmest month is February, the coolest month is July, the wettest month is May, and June is the driest month.
What is Climate Change?
Climate Change means big changes in the weather of a place, that stay for a long time.
In some places, these changes can mean more or less rain, or more or less sun.
There are many things that cause climate change…
-Cut down trees
Most of this happens in South America, because a lot of farmers there tend to burn down trees to create farmland. Also, since 1990, In Brazil, more than 163,000 square miles of rainforest has been it down.
This leads to, animals losing their habitats and the trees not getting there oxygen!
-use gasoline or fossil fuels
(Gasoline is petrol used in vehicles. Fossil Fuels are a natural fuel such as coal or gas)
These two activities release carbon dioxide into the atmosphere, which holds in heat from the gases, meaning the climate becomes warmer.
– Heat wave
-Volcanos (Volcanos have very big impact on climate change. When a volcano erupts, the ashes can block the suns rays causing cooler weather for years)
What we can do to help
-Don’t use vehicles that run on gases or petrol
(Because carbon dioxide is the most important greenhouse gas, so planting trees can slow or stop global warming)
(That means to save and not waste it.)
There is a lot of things that we can do to help. But none of them will be perfect. But lots will have potential.
If you use electricity a lot, you are realising over 400 grams of CO2.
We will have to decrease trillions and trillions of CO2 to at least just slow Global Warming.
How does Climate Change work?
Revolution and Rotation are a a big part of Climate Change. It causes the seasons and that’s what causes Climate Change.
Depending on where you live, in summer, one week may be hot and sunny, than the next week it may be FREEZING and RAINY!!!
What is global warming?
Global Warming means the world is warmer than it was a hundred years ago.
There is even global warming going on right now. And for some people it is NOT a good thing.
The ice from Antarctica melts, which means that the melted ice will increase ocean levels. Australia will probably not be affected as our country is very big. But some of the other little and low islands without any mountains islands may not exist in the future. As the melted ice increases the sea level, it may flood the islands or may even send the WHOLE ISLAND UNDERGROUND!!!
For the past twenty years the Solomon Islands have been a hotspot for flooding.
For twenty years, Hawaii, have been Carbon dioxide in the ocean.. It’s been steadily increasing.
But why is it melting? It’s all humans fault.
26% of ocean acidity has been increased by humans.
The gases that we realise get trapped in the atmosphere making it hotter. This makes the ice melt.
By the end of this century scientist are expecting 170% of ocean acidification will increase.
This is 10x faster than it has been in 55 million years. Many sea creatures are giving negative responses. This is saying a lot of sea creatures will soon to be extinct.
Crabs, Oysters and coral are what are needed to build reefs. Soon, if the increase of carbon dioxide continues, they will start to dissolve. For example a sea butterfly, after just 45 days it all dissolved.
25% of coral supports the ocean in the world. Scientists have had tests, and just after perfect shaping and forming, 6 months is all it takes for a whole fully grown coral to dissolve.
The weather will increase by 2 degrees every 2 years.
The Solomon Islands are close to New Guinea and and Australia.
The Green House
A green house without fans, the earth will heat up. It is warmed by 1.8 degrees. This may seem very small until you consider that the planet warmed by 7 degrees in the previous 12,000.
