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

　　 trickle flows out from the crevices of the glacier, water droplets from the top, gather on the outside of the honeycomb, and then heat into water vapor at high temperature.

　　 The first cumulonimbus cloud appeared since the ice age when the progress of laying beehives on the ground reached one-third.

　　 However, this thick cumulonimbus cloud is not raining.

　　 The honeycomb heats water into water vapor, and the steady stream of steam melts the top ice layer into a channel leading to the uppermost layer of ice, and then continues to rise and become a cloud.

　　 The heat-rich cloud releases a large amount of heat at a high altitude, and it condenses to form ice crystals and fall back to the surface.

　　 So, the first scene after the thawing was not rain, but hail.

　　 This is a process of alternating hot and cold. Hail brings the cold air mass in the upper layer to the surface, while the hot air remains on it. At this time, the role of the north and south poles becomes prominent.

　　 Atmospheric circulation begins to operate.

　　The hot air is divided into countless parts under the action of atmospheric circulation and scattered in every part of the planet.

　　 It seems that the heating of the honeycomb has become meaningless, the falling hail thickens the ice layer, and the resulting hot air mass spreads over the entire planet due to the atmospheric circulation, and the heating effect is minimal.

　　 However, there are some things that cannot be seen in this way. You need to change the angle. This may not be the fastest way to see the warming effect, but the gentlest way.

　　 The existence of atmospheric circulation allows the planet to warm up and there is a buffering process, rather than abrupt completion, which would trigger a catastrophic natural phenomenon.

　　Honeycomb heating is a continuous process. Even if there is more hail, it will be reheated into water vapor. If it goes back and forth, the planet will be as peaceful as possible to achieve an overall heating up.

　　 In more and more places, the ice layer is collapsing, and the pools around the honeycombs have become ponds, gradually expanding from the ponds into large lakes.

　　 The water level rises again and again, and it quickly passes the height of the hive, placing it all at the bottom of the water.

　　Everything is going in a good direction.

　　 Seeing that it was almost the same, Huo Gu activated the native microorganisms that Ming had collected before, and put them out one by one.

　　 Among these microorganisms, there are autotrophic and heterotrophic types, but Huogu is treated equally, and there is no difference between them. What kind of microorganisms will develop later has nothing to do with it.

　　 As time passes by day by day, Huogu can't be regarded as idle. It needs to constantly monitor the operation process of various large-scale biological systems to avoid accidents.

　　 The temperature rise continues, but the circular lake with the honeycomb as the center has not expanded as fast as it was at the beginning. Although it is still expanding year by year, the rate of expansion does show a decreasing trend.

　　 Regarding this kind of thing, Huogu has noticed, but he doesn't care about it very much.

　　 This is the illusion of diminishing efficiency caused by the expansion of the circular lake.

　　 Because each honeycomb has its own limit on the amount of heat produced, the amount of glacier melted every year is so large. If you carefully calculate the area according to the area, you will find that the ice melting efficiency of the honeycomb has not actually decreased.

The reason why 　　 appears to show a decreasing trend is that the radius of the circular lake is extended, and the area of ​​the circle increases geometrically every time it extends a certain distance.

　　 However, there is indeed something that Huogu will pay more attention to.

　　 I don’t know when, the pitch-black sky finally changed a little, showing some signs of bias towards blue.

　　 This sign is very weak, but it can't escape the visual organs of Hoguna's design after many optimizations, modifications and adjustments. The sensitivity to the gradient of spectral tones has far exceeded the scope of the human eye.

　　 Obviously, there are some other components in the atmosphere. These unclear substances interfere with the light irradiated to the surface to a certain extent, so this phenomenon will occur.

　　 "Very good, finally it's almost there."

　　 The visual system on the rhizome is locked to a small black spot from the sky, and the small black spot is still rapidly zooming in, something is rushing towards the hive.

　　 Soon, the unknown thing has dropped to a certain distance.

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

　　 "Keep it open."

　　 The order was given, and the thing burst out from the tail of a parachute-like membrane, its speed dropped rapidly, and then it fell into the water a few meters away from the hive.

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

　　 This object is a biological collection bottle with a very simple internal structure. It is a hollow structure similar to bamboo. Its strength depends entirely on the titanium alloy shell. It is specially manufactured by Huogu to collect air samples.

　　 Not long ago, in order to explore the reasons for the discoloration of the sky, Huo Gu launched this biological collection bottle into the sky like the last time~lightnovelpub.net~ to collect samples of the current atmosphere.

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

　　 Roots were inserted into the bottle and began to analyze the composition ratio of the air sample inside.

　　 The first thing that was noticed was carbon dioxide, because of the ingredients inside, carbon dioxide accounted for the largest proportion.

　　 "Well, as the glacier melts, part of the dioxide is trapped in the ice, and the carbon dioxide that becomes dry ice is re-added to the planet's atmosphere..."

　　 "Methane of a certain composition seems to be the survivor of the last game..."

　　 This Huogu was not surprised. Although the octahedron is a big methane consumption, it is impossible to consume all the methane reserves of the planet at once.

　　 "Huh? Oxygen?"

　　 "No! This molecular structure is... ozone?"

　　 Ozone is a light blue gas with a special smell. The conditions for its formation are oxygen plus electric shock.

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

　　Hogu understands what the appearance of ozone means. This sign has shown that after a while, the ozone layer will form.

　　 The ozone layer can absorb 99% of the ultraviolet radiation in the sun, and this energy will stay high in the sky, heating the air mass, and ozone itself is a greenhouse gas.

　　 When the ozone layer has a certain scale, the pressure on Hogu side will be reduced. The ozone layer can also provide temperature to the planet's environment, and the planet's heating rate will be further improved.

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