Since the melting of glaciers is bottom-up, when the hive heats up the surface of the planet, it will also be accompanied by the collapse of the glacier from time to time, but the structural strength of the hive itself is very high, and this can be ignored.

A trickle of water flows out of the crevices of the glacier, and the droplets from the top collect on the outside of the hive, which is then heated into water vapor in high temperatures.

At a third of the ground hive laying area, the first cumulonimbus cloud since the Ice Age appeared.

However, this thickening Cumulonimbus cloud is not raining.

The hive heats the water into water vapor, and the constant flow of steam, after melting the top ice into a passage to the topmost ice, continues to rise and become a cloud.

Heat-rich clouds release large amounts of heat at once at high altitude, condensing to form ice crystals that fall back to the surface.

So, the first thing that fell after the thaw was not rain, but hail.

It is a process of alternating heat and cold, with hail carrying the cold air masses from the upper layers to the surface and the hot air remaining on them, and the role of the north and south poles comes into being.

Atmospheric circulation becomes operational.

The hot air is broken up by atmospheric circulation and scattered everywhere on the planet.

It seems that the heating of the hive has become meaningless, the falling hail thickens the ice, and the created hot air masses are scattered throughout the planet due to atmospheric circulation, and the warming effect is minimal.

However, there are some things that don't look that way and need to be looked at from a different angle, which may not be the fastest way to see the warming effect, but the gentlest way.

The existence of atmospheric circulation, so that the planet warms up this kind of thing can have a buffer process, rather than abruptly accomplished, from triggering a catastrophic natural phenomenon.

Hive heating is a continuous process, and even the most hailstones will be reheated into water vapor, and so on, and the planet will heat up as a whole in as peaceful a way as possible.

Ice is collapsing in more and more places, and the waterholes around the hives are becoming ponds, which are gradually expanding from ponds to large lakes.

The water level rises again and again, and soon overflows the height of the hive, placing it all under the water.

Everything is going in a good direction.

Seeing that the time was almost there, Huo Gu activated the proto-microorganisms that he had collected before, and released them one by one.

Among these microorganisms, there are autotrophic and heterotrophic types, but Huogu is treated equally, there is no difference, and it has nothing to do with what the microorganisms will develop into later.

Time passed day by day, and Huo Gu could not be regarded as idle, it had to monitor the operation process of each large biological system at all times to avoid unexpected situations.

The warming continues, but the circular lake centered on the beehive is not expanding as fast as it used to be, and although it is still expanding year by year, the rate of expansion is indeed decreasing.

Hogu had noticed this kind of thing, but it didn't really care about it.

This is an illusion of diminishing efficiency caused by the expansion of the area of circular lakes.

Because each hive has its own limit to the amount of heat it can produce, and the amount of glacier melt each year is so much, if you carefully calculate the area, you will find that the ice melting efficiency of the hive has not actually decreased.

The reason why it appears to be decreasing is that the radius of the circular lake increases, and the area of the circle increases exponentially with each distance extended.

However, there are indeed things that Huo Gu will pay more attention to.

I don't know when it started, but the inky sky finally changed a little, and there were some signs of a blue bias.

The signs are faint, but they can't escape Hoguna's visual organs, which have been optimized and modified many times, and their sensitivity to spectral hue gradations has far surpassed the scope of the human eye.

Obviously, there are some other components in the atmosphere, and these substances that are not yet clear about the body form a certain degree of interference with the light emitted to the surface, so this phenomenon occurs.

"Good, it's almost there."

The visual system on the rhizome locked onto a small black dot from the sky, and the small black dot was rapidly magnifying, and something was rushing towards the hive.

Soon, the unknown had descended to a certain distance.

"The structure is relatively brittle, so it's better to pay attention to it when it falls."

"Stretch out."

The command was given, and the thing burst out of its tail with a parachute-like membrane, which dropped rapidly, and then crashed into the water a few meters from the hive.

The rhizome has been waiting for a long time at the bottom of the water, engulfing the object into the rhizome system.

The object is a bio-type collection vial, with a simple internal structure, a hollow structure similar to bamboo, and its strength is completely dependent on a titanium alloy shell, which Hogu specially manufactured to collect air samples.

Not long ago, in order to explore the cause of the sky's discoloration, Hogu launched this biotype collection vial into the sky like he did last time, collecting samples of the current atmosphere and returning from it.

According to Hogu's experience, the color of the sky depends mainly on the composition of the atmosphere at that time, such as the orange-red sky during the Plutozoic period and the blue sky of the earth.

One by one, the roots poke into the bottle and begin to analyze the composition of the air sample inside.

The first thing that catches the eye is carbon dioxide, because it is the largest component of carbon dioxide.

"Well, as the glaciers melt, some of the carbon dioxide trapped in the ice, and the carbon dioxide that became dry ice, were readded to the planet's atmosphere......"

"Methane with a certain component, it seems to be a survivor of the last competition......"

This Huo Gu was not surprised, although the octahedron is a large consumer of methane, it is impossible to deplete all the planet's methane reserves at once.

"Huh? Oxygen? ”

"That's not right! This molecular structure is...... Ozone? ”

Ozone is a light blue gas with a special odor that is formed by oxygen and electric shock.

In this way, the gradual change in the color of the sky can be explained, and it is precisely because of this ozone that the color of the sky is changed.

Hogu understood what the appearance of ozone meant, a sign that the ozone layer would form in a little while.

The ozone layer absorbs 99% of the ultraviolet radiation in sunlight, and this energy is left high in the air, heating air masses, and ozone itself is a greenhouse gas.

When the ozone layer reaches a certain size, the pressure on the Hogu side will be reduced, and the ozone layer can also provide temperature to the planet's environment, and the rate of planetary warming will be further improved.

Time flies, and for some time after that, except for the north and south poles, the glaciers completely disappeared and the lake became the sea.
