Homo sapiens

It’s been another three years of mending things on the International Space Station.

Rogers, who had just come up some time ago, was currently wearing a heavy space suit and repairing some old-fashioned heat sinks outside the cabin.

Suddenly he turned his head and looked in the direction of the earth.

At this time, the space station is just over the Mediterranean region, and Europa, the Mediterranean Sea and the Sahara can be seen.

He has been busy repairing the internal facilities of the space station these days and has not taken a closer look at the earth.

'The blue Mediterranean is so beautiful...'

"Huh? That's it?"

When his eyes shifted to the Sahara Desert, his expression froze.

Because he discovered that the northeastern part of the Sahara Desert was actually green at this time, which somewhat subverted his previous knowledge.

Rogers didn't think too deeply. He continued to enjoy the scenery of the earth for a while, and then concentrated on his work.

However, on earth, many people are paying attention to the greening of the Sahara Desert.

Thanks to the tireless transformation of Homo sapiens, nearly 840,000 square kilometers of desert in the northeastern part of the Sahara Desert have been transformed into green-covered farmland, plantations and saltwater lakes.

The total area of ​​the Sahara Desert is only about 9 million square kilometers.

In other words, nearly one-tenth of the Sahara Desert has been transformed at this time.

Due to the very tense relationship between the Homo Sapiens Company and the Europa Consortium and the Free Association, the two sides now do not have much contact with each other, and even civil aviation and commercial transportation have been almost interrupted.

But in North Africa, French influence remained deeply entrenched.

For example, the Republic of Abdelwad to the west of Numidia, although it had been in love with France for more than two hundred years, they eventually turned against each other.

But they still did not refuse some cooperation from France.

On the border between the Republic of Abdwaid and Numidia.

A climate and environment research team in France is collecting various data at this time.

On a five-story building in the town, Dr. Lena, wrapped in a headscarf, put down the telescope: "Have they dug the canal to this side?"

Major Patton of the Foreign Legion spread his hands: "We dug here two weeks ago."

Dr. Lena looked at the historical monitoring records of the local weather, with a hint of worry on her face: "The air humidity here has increased by 5.6 to 7.2%, and this number may continue to increase in the future."

"Isn't this a good thing?" Barton, who didn't know much about environmental science, didn't think there was a problem.

"Everything has two sides." Dr. Lena said casually, but did not continue to explain, but asked: "Mr. Major, how is the status of our visa application to Numidia and Suez?"

Barton shrugged: "We didn't pass. The other party refused to let our people enter. Unless the whole family goes to work together, it will be difficult to pass."

Hearing this, Dr. Lena showed a hint of disappointment on her face.

Although she is a top environmental scientist in the Europa region, this status does not qualify the Homo sapiens company to make an exception for this.

Dr. Lena, who has not obtained a visa, can only analyze climate changes in the Sahara Desert through satellite detection data.

Through a large number of meteorological satellite detection data, her team has discovered that some climate changes have occurred in the sand kingdoms of northeastern Sahara and West Asia.

This climate change is somewhat different from previous climate changes.

According to the research of Dr. Lena's team, this time the climate change in the northeastern part of the Sahara Desert is extremely rapid, and the impact range is very large.

The reason for this situation has a lot to do with the large-scale use of seawater to irrigate farmland by Homo sapiens companies.

Many people who have studied the Sahara Desert and the West Asian Desert know that the reason for the formation of this desert area is the subtropical high pressure, as well as factors such as topography, location, and ocean currents.

The subtropical high pressure has prevailing downdrafts all year round, which is not conducive to precipitation. In addition, the seasonal northeast trade wind blows from the interior of West Asia and Central Asia. Naturally, it does not carry much water vapor, and it is also unable to form rainfall.

But at this time, the Sahara "greening" project of Homo Sapiens Company is different.

A large number of saltwater canals, artificial lakes, ditches, and large-scale irrigation have greatly increased the amount of water vapor evaporation in the northeastern Sahara Desert.

Some people may say, isn’t it just some canals, artificial rivers, and paddy fields? How much can this increase evaporation?

The Red Sea Province in the Suez region, next to the Red Sea, is still a desert.

However, Dr. Lena's research team found that the amount of water evaporation in the northeastern part of the Sahara Desert at this time was almost 5 to 6 times the total evaporation of the Red Sea.

This is absolutely terrifying.

There are three main reasons why such a huge amount of water vapor is produced: the vast area of ​​the water body, the high temperature, and the shallow depth of the water body.

The Red Sea only covers an area of ​​438,000 square kilometers, but the artificial water bodies and seawater-irrigated farmland transformed by Homo Sapiens in North Africa cover an area of ​​887,000 square kilometers, almost twice the area of ​​the Red Sea.

If the water body is too shallow and there is sufficient solar energy, the temperature of the water body will easily increase, thereby increasing the evaporation efficiency of the water body.

No matter how strong the subtropical high pressure is, there is no way to offset the water vapor equivalent to 5 to 6 Red Sea evaporations.

Moreover, the Homo sapiens company continues to expand the area of ​​plantations and paddy fields in North Africa, and digs canals to the Chad and Meroe areas.

The entire eastern Sahara may be dyed green in the future, and evaporation will further increase.

The central region of the Sahara Desert will definitely be affected. It is very possible that the climate will become wetter and the desert will turn into grassland.

Perhaps this is a good thing for the Sahara region, but not necessarily for other regions.

The reason why Dr. Lena is worried about this is because she knows that the global climate is a whole. When the climate in one area suddenly changes, it will inevitably affect other areas. This is something that cannot be avoided.

The transformation of the Sahara Desert by the Homo Sapiens Company is almost permanent, which will lead to drastic changes in the climate model of the entire Sahara Desert region.

This drastic change in climate has a huge impact on agricultural production.

When it comes to climate requirements for agricultural production, the first factor is stability, followed by suitability.

If the climate is unstable and there are sudden heavy rains this year, continuous drought next year, and April snowfall the year after that, open-air agriculture will definitely be hit hard.

Dr. Lena returns to her temporary home.

A local meteorological researcher held a document and greeted Dr. Lena: "Dr. Lena, we have obtained an invitation letter to the African Climate Forum. The forum will be held in Cairo."

"But I don't have a visa." Dr. Lena said helplessly.

"Doctor, you are too rigid."

Dr. Lena quickly asked: "Robin Hood, what can you do?"

"Wouldn't it be great if you applied to become Abd's nationality?" Robin Hood reminded him with a wink.

"What?"

"You should be able to find a way."

Dr. Lena thought for a while and finally nodded. She quickly called her embassy and contacted several old acquaintances in France.

Soon her idea was approved, and she agreed to help run the operation to quickly naturalize Abed. After participating in the African Climate Forum, she can directly apply for restoration of nationality.

Three days later, Dr. Lena, Robin Hood and others took a plane to Cairo to attend the African Climate Forum.
