Transcripts

Can you feel the cold breeze now?

The wind passes through the frozen parts of the world.

That’s why we experience a cold breeze.

But what if it melts?

What are the effects of ice melting on the world?

And why should Filipinos worry about it?

Here’s what you need to know.

10% of our world is covered in ice.

Most of the glaciers and sea ice are found

in countries in the Arctic Circle like Svalbard in Norway,

Greenland; there is the Antarctic region at the South Pole.

There are also in the Himalayan region.

68% of freshwater is stocked here.

Many countries, especially Himalayan region,

drink water from glaciers.

According to experts like Dr. Heidi Sevestre, a French glaciologist,

the cryosphere ecosystem or the part of the world that has ice is said to be a big help.

Some of them are snow, glaciers and sea ice.

It's like a mirror in space that keeps the world cool.

Even though we don’t have snow in the Philippines,

because of the cryosphere,

we are experiencing cold weather.

The whiter they are, the more they can send all the heat

we get from the sun away.

So these white surfaces,

they are the best air conditioning we have on earth.

So even if you live in the Philippines,

you actually are somehow connected to Arctic sea ice

up north around the North Pole.

In the past decade,

scientists noticed the rapid melting of the cryosphere.

The use of fossil fuels and deforestation

are some of the reasons why the world continues to warm

and a faster melting of ice.

If the ice in the Arctic Circle and Antarctica continues to melt,

it is said that sea levels worldwide could potentially rise.

Today, we know that glaciers around the world

are reacting very quickly to climate change.

If you look at what we call mountain glaciers,

the glaciers of the Himalayas, of the Alps, of Alaska,

if they all disappear, sea levels around the world

would increase by about 40 centimeters,

which is already a lot for many countries.

But then, if you look at what's happening

further away in Greenland, for example, or in Antarctica,

there is a lot more ice in these ice sheets.

For example, if Greenland were to disappear,

sea levels around the world would increase by six to seven meters,

bearing in mind that in the Philippines,

the ocean is rising even faster.

The gradual melting of the ice is also not good news in Antarctica.

This year, we've never had so little Antarctic sea ice

when it's supposed to be the maximum amount

of sea ice of the year.

And the consequences of this are very important

because Antarctica seems to be losing its own air conditioning.

And the fact that we are losing Antarctic sea ice

is already impacting the ocean circulation around the world.

Our big ocean currents need sea ice

in the polar regions to function properly.

And the fact that we're losing Antarctic sea ice

is not good news for any of us on the planet.

When the ice in Antarctica finally melts,

sea ​​level may rise by 58 meters

or equivalent to fifteen floors of the building.

The consequences are already being felt right now.

Its issues with our water resources, you know.

We expect to get water from mountain glaciers

during the summer months.

It's issues with sea level rise

that you're already feeling deeply in the Philippines.

And it's also consequences on our everyday weather.

If the sea level continues to rise due to ice melting,

some areas are now at risk of submersion,

inucluding the Philippines.

This is being monitored by the National Mapping and Resource Information Authority

or NAMRIA.

Because Philippines is an archipelago,

the rising water levels have various effects.

So we call it localized sea level.

In all parts of the Philippines, Manila is the highest.

Manila is not just the center of commerce.

It is also surrounded by the sea, such as Manila Bay.

Besides Manila, the rise in water level in Cebu and Davao was also monitored.

That's why NAMRIA continues to gather data

in other areas of the country.

We have installations apparently.

We have what we call a tide station.

So we have 60 of those operating 24 hours, 365 days a year.

Out of 60 stations across different parts of the country,

13 stations have been observed with a continuous rise in water levels.

This includes Manila.

Besides sea level rise,

the so-called migration pattern of other animals

such as whales and birds is also affected.

The melting ice, the melting cryosphere

is not just impacting sea levels and water resources.

It's also directly impacting

the inhabitants of these environments.

And we know that certain species in the oceans,

for example, are very specific about the salinity of the water

the temperature of the water.

And the fact that ice sheets and sea ice

are disappearing very rapidly

is directly impacting these species

that are really experts of a certain ecological niche.

But will need time to adapt to these rapid changes.

And what these species don't have right now

is time to adapt.

If climate change continues to worsen

and human use of fossil fuels will not change,

the sixth extinction might possibly happen

or depletion of natural resources in the future.

Today, if we do not invest in fighting the climate crisis,

we are investing in a future

that will be very, very difficult for all of us.

So it's a win-win.

If we fight the climate crisis together,

then, our future can be better

for each and every single one of us.

Let's keep hope.

Let's keep fighting.

Let's keep working to fight the climate crisis.

And there's everything to gain from it.
