Hi, my name is Anne.
- 00:01 - 00:01
Hi,
- 00:02 - 00:04
I'm bobby hall and I'm Jared gray and we're gonna
- 00:04 - 00:06
be talking about hurricanes and climate change's effects on them.
- 00:07 - 00:09
I'm going to be talking about photosynthesis and
- 00:09 - 00:11
cellular respiration and the balance between them.
- 00:11 - 00:13
But first I'm going to define that
- 00:14 - 00:15
through photosynthesis,
- 00:15 - 00:18
plants produce oxygen and have contributed to making earth
- 00:18 - 00:21
a habitable planet through the process of photosynthesis.
- 00:21 - 00:22
During the day,
- 00:22 - 00:25
plants take up carbon dioxide from the air and converted
- 00:25 - 00:28
into sugar and then release oxygen into the atmosphere.
- 00:28 - 00:33
This oxygen is then used in all forms of life and cellular respiration.
- 00:34 - 00:40
Um and this through cellular respiration, carbon dioxide is released.
- 00:42 - 00:46
Both cellular respiration and photosynthesis are biological processes in
- 00:46 - 00:48
which matter and energy flow through the biosphere.
- 00:49 - 00:52
These two processes are responsible for the exchange of oxygen
- 00:52 - 00:55
and carbon dioxide between living organisms and the environment.
- 00:55 - 00:58
There is a unique balance between the two and climate
- 00:58 - 01:00
change has caused a dis regulation between the two.
- 01:01 - 01:02
Next,
- 01:02 - 01:04
we'll talk about what climate change is and how is
- 01:04 - 01:07
it how it is affected by cellular respiration and photosynthesis.
- 01:07 - 01:09
What is climate change?
- 01:09 - 01:13
Climate Change refers to the long term shift and temperature or weather patterns.
- 01:13 - 01:17
These shifts may be natural, such as through variations in the solar cycle.
- 01:17 - 01:18
But since the 1800s,
- 01:18 - 01:21
human activities have been the main driver and climate
- 01:21 - 01:24
change primarily due to fossil fuels like coal,
- 01:24 - 01:25
oil and gas.
- 01:26 - 01:31
During global warming, the amount of carbon dioxide in the atmosphere increases.
- 01:31 - 01:36
Alright, so now I'm going to define what a hurricane is
- 01:36 - 01:40
in a hurricane spiraling winds draw moist air towards the center,
- 01:40 - 01:44
fueling the towering thunderstorms throughout it in the diagram, you can see this
- 01:46 - 01:50
so there's four main ingredients that basically make up a hurricane first.
- 01:50 - 01:51
You need warm water.
- 01:51 - 01:55
When the surface water is warm, the storm sucks up heat energy from the water,
- 01:55 - 01:57
just like a straw sucks up liquid.
- 01:57 - 01:58
Let's think about atoms.
- 01:58 - 01:59
When you heat up an atom,
- 01:59 - 02:02
it moves faster so they like bounce off
- 02:02 - 02:05
each other and that's basically what's happening here.
- 02:05 - 02:06
This creates moisture in the air.
- 02:06 - 02:09
If wind conditions are right, the storm becomes a hurricane,
- 02:09 - 02:11
this heat energy is the fuel for the storm.
- 02:11 - 02:14
So basically the warmer the water, the stronger the hurricane
- 02:16 - 02:17
moisture
- 02:17 - 02:20
when water vapor condenses into the atmosphere,
- 02:20 - 02:22
it releases heat that helps to fuel the storms.
- 02:22 - 02:24
Like I talked about just a second ago,
- 02:24 - 02:27
warm water releases vapor and then that goes
- 02:27 - 02:29
into the atmosphere and it starts spiraling,
- 02:29 - 02:30
spiraling around
- 02:34 - 02:35
low wind.
- 02:35 - 02:37
This term refers to the change in wind speed
- 02:37 - 02:40
or direction that it travels upwards in the atmosphere.
- 02:40 - 02:43
Think about if you have a stack of Jenga blocks,
- 02:44 - 02:48
if you were to push it all at the same force from every single side,
- 02:48 - 02:49
nothing would happen.
- 02:49 - 02:53
It was just all equal out and then the Jenga box wouldn't fall over.
- 02:53 - 02:53
However,
- 02:53 - 02:58
if you have different speeds and different directions and also
- 02:58 - 03:01
um different forces the Jenga blocks will tumble over.
- 03:01 - 03:02
So if I'm hitting it from the top
- 03:02 - 03:06
and bottom at different angles and different speeds,
- 03:06 - 03:08
there's gonna be a dis regulation.
- 03:08 - 03:12
So when you have a low wind and it doesn't affect the hurricane,
- 03:13 - 03:17
the hurricane actually can keep spinning because there aren't winds to stop it.
- 03:17 - 03:20
So when you have a lot of wind and it's hitting it from all different angles,
- 03:20 - 03:24
like the Jenga blocks it tumbles and that's how you diffuse a hurricane.
- 03:25 - 03:30
Lastly disturbance, hurricanes are usually set off by train chain reactions,
- 03:30 - 03:32
whether it's a storm that occurred,
- 03:32 - 03:35
um like down in Mexico will feel the reaction of it.
- 03:35 - 03:40
That's what a lot of hurricanes are. Um but yeah, something has to start.
- 03:40 - 03:42
It just doesn't randomly occur.
- 03:47 - 03:51
Alright, so now let's talk about climate change and hurricanes.
- 03:51 - 03:53
So on a quote from Nasa,
- 03:53 - 03:53
they said,
- 03:54 - 03:55
due to global warming,
- 03:55 - 03:57
global climate models predict hurricanes will likely
- 03:57 - 03:59
cause more intense rainfall and having an
- 03:59 - 04:03
increased coastal flood risk due to higher storm surge caused by rising seas.
- 04:03 - 04:04
Additionally,
- 04:04 - 04:07
the global frequencies of the stone may decrease or remain uncharged,
- 04:07 - 04:10
but hurricanes that form are more likely to become intense.
- 04:10 - 04:11
Similarly,
- 04:11 - 04:13
they're actually won't be an increase in hurricane,
- 04:13 - 04:15
but more so an increase in the force
- 04:15 - 04:18
of the hurricanes increased force means more damage.
- 04:18 - 04:20
So we'll be suffering probably more.
- 04:20 - 04:23
So there's three main things that are impacted by climate change,
- 04:23 - 04:26
increased water temp, increase the level and increased force,
- 04:26 - 04:27
let's talk about him.
- 04:30 - 04:34
So as I talked about when I was defining a hurricane, increased water temps?
- 04:34 - 04:37
So the hotter the water, the more moisture that's in the air.
- 04:37 - 04:40
So when you have a water hurricane that actually causes more rainfall,
- 04:40 - 04:45
so 10 to 15% more precipitation from storms are projected with climate change.
- 04:45 - 04:48
Recent storms such as Hurricane Harvey in 2017,
- 04:48 - 04:51
which dropped more than 60 inches in some locations
- 04:52 - 04:57
And then there was Florence in 2018 with over 35" and Imelda in 2019,
- 04:57 - 05:00
which dropped 40 for demonstrate that climate change
- 05:00 - 05:02
is really affecting how much rain is falling
- 05:02 - 05:06
now increased sea level.
- 05:06 - 05:09
So the sea levels are increasing because the polar
- 05:09 - 05:12
caps are melting basically when the glaciers melt,
- 05:12 - 05:14
What happens when you melt ice?
- 05:14 - 05:16
There's more water and our sea levels are rising.
- 05:16 - 05:18
So when the sea level rises,
- 05:18 - 05:20
that means there's more of an impact from the
- 05:20 - 05:22
hurricanes as the surge is a lot stronger.
- 05:22 - 05:25
Researchers suggest that the most damaging us hurricanes
- 05:25 - 05:28
are three times more frequent than 100 years ago
- 05:28 - 05:32
And that is a proportion of major hurricanes, category three or above.
- 05:32 - 05:39
And the Atlantic Ocean has doubled since 1980. That's a big, big drastic change.
- 05:39 - 05:42
So it's really important that we are conscious about this
- 05:42 - 05:45
and care about how much water is in our oceans
- 05:48 - 05:50
increased force,
- 05:50 - 05:53
more water equals more damage and more power equals more
- 05:53 - 05:58
damage we've seen in recent hurricanes such as Katrina Harvey,
- 05:58 - 06:03
just how monstrous these um ocean swells can be.
- 06:03 - 06:06
It's really sad to see how many people are displaced and
- 06:06 - 06:09
also have to deal with damaged homes because of this.
- 06:09 - 06:11
And it's really sad. So
- 06:12 - 06:13
how can you help?
- 06:17 - 06:20
The most important things you can do are being conscious about what you consume.
- 06:20 - 06:23
Not one person is going to be able to solve climate change,
- 06:23 - 06:27
but if we all work together, we'll have more of a greater impact.
- 06:27 - 06:28
Another way that you can help is to
- 06:28 - 06:31
support brands that support ending climate change.
- 06:31 - 06:33
Some of these are like Patagonia things.
- 06:33 - 06:33
Yes,
- 06:33 - 06:36
straws just being really conscious about what you
- 06:36 - 06:37
take from our planet and then what you
- 06:37 - 06:41
put back into it is the best way that you can help in a hurricane.
- 06:41 - 06:44
And then if we were to magically come up with a solution,
- 06:44 - 06:47
we would basically need to decrease water temperatures and
- 06:47 - 06:51
then also decrease how hot our atmosphere is getting.
- 06:51 - 06:55
Thank you for listening. I hope you enjoyed our presentation bobby.
- 06:55 - 06:56
Any final words?
- 06:57 - 07:01
It's a, it's a major problem that we need to solve now
