Chapter 480 Huge Evaporation
Patching up the International Space Station for another three years.
Rogers, who had just come up some time ago, was wearing a heavy space suit and repairing some old-fashioned radiators outside the cabin.
Suddenly he turned his head and looked towards the earth.
At this time, the space station was just above the Mediterranean region, and could see Europa, the Mediterranean Sea and the Sahara.
He has been busy repairing the internal facilities of the space station these days and has not yet taken a close look at the Earth.
'The blue Mediterranean Sea is so beautiful...'
"Huh? What is that?"
When his gaze shifted to the Sahara Desert, his expression froze.
Because he discovered that the northeastern part of the Sahara Desert was green at this time, which somewhat overturned his previous cognition.
Rogers didn't think too deeply about it. He continued to appreciate the scenery of the earth for a while, and then concentrated on his work again.
However, on Earth, many people are paying attention to the greening of the Sahara Desert.
Thanks to the unremitting transformation of Sapiens, nearly 840,000 square kilometers of desert in the northeastern part of the Sahara Desert have been transformed into green farmlands, 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.
Due to the extremely tense relationship between Sapiens and the Europa Union and the Free Union, the two sides do not have much contact with each other now, 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 Abd al-Wad west of Numidia, although it had been in a love-hate relationship with France for more than two hundred years, finally turned against each other.
But they did not refuse some of France's cooperation.
On the border between the Republic of Abd al-Wad and Numidia.
A French climate and environmental research team is currently collecting various data.
In a five-story building in the town, Dr. Lena, wrapped in a headscarf, put down her telescope and asked, "Have they dug the canal to this side?"
Major Patton of the Foreign Legion spread his hands and said, "We dug here two weeks ago."
Dr. Lena looked through the local weather monitoring records, a trace of worry on her face: "The air humidity here has increased by 5.6-7.2%, and this number may continue to increase in the future."
"Isn't this a good thing?" Patton, 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. Instead, she asked: "Mr. Major, how is our application for visas to Numidia and Suez?"
Barton shrugged. "No. They refused our entry. Unless the whole family goes there to work, 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 Europe, this identity does not qualify Sapiens to make an exception for her.
Without a visa, Dr. Lena could only analyze climate change in the Sahara Desert through satellite detection data.
Her team has discovered some climate changes in the northeastern Sahara and the Saudi Kingdom in West Asia through a large amount of meteorological satellite detection data.
This kind of 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 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 by Homo sapiens companies to irrigate farmland.
Many people who have studied the Sahara Desert and the West Asian Desert know that the formation of this desert area is the subtropical high pressure, as well as factors such as terrain, location and ocean currents.
The subtropical high pressure system is characterized by downward air currents all year round, which is not conducive to precipitation. In addition, the seasonal northeast trade winds blow from the interior of West Asia and Central Asia, so they naturally do not carry much water vapor and are also unable to form rainfall.
But the Sahara "greening" project of the Sapiens Company is a little different.
A large number of saltwater canals, artificial lakes, and aqueducts, as well as extensive irrigation, have greatly increased evaporation in the northeastern part of the Sahara Desert.
Some people may say, aren’t they just some canals, artificial rivers, and paddy fields? How much can this increase the evaporation rate?
The Red Sea Province in the Suez region is right next to the Red Sea, but it 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 just horrifying.
There are three main reasons why such a huge amount of water vapor is generated: the water area is vast, the temperature is high, and the water depth is shallow.
The Red Sea covers an area of only 438,000 square kilometers, while the artificial water bodies and seawater irrigated farmland created by Sapiens in North Africa cover an area of 887,000 square kilometers, almost twice the size of the Red Sea.
If the water body is too shallow and there is abundant solar energy, the water temperature will easily rise, thereby increasing the evaporation efficiency of the water body.
No matter how strong the subtropical high pressure is, it cannot offset the water vapor of 5 to 6 times the evaporation of the Red Sea.
In addition, the Homo sapiens company continued to expand the area of plantations and paddy fields in North Africa and dug canals to Chad and Meroe.
In the future, the entire eastern Sahara region may be dyed green, and evaporation will further increase.
The central region of the Sahara Desert will definitely be affected, the climate will become more humid, and it is very likely that the desert will turn into grassland.
Maybe 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 changes suddenly, it will inevitably affect other areas. This is something that cannot be avoided.
The transformation of the Sahara Desert by Sapiens is almost permanent, which will cause dramatic changes in the climate model of the entire Sahara Desert region.
This drastic climate change has a huge impact on agricultural production.
The first requirement for climate in agricultural production is stability, followed by suitability.
If the climate is unstable, with sudden heavy rains this year, continuous droughts next year, and snow in April the year after, open-air agriculture will definitely be hit hard.
Dr. Lena returned to her temporary residence.
A local meteorological researcher held a document and greeted Dr. Lena, "Dr. Lena, we got an invitation letter to the African Climate Forum to be held in Cairo."
"But I don't have a visa." Dr. Lena said .
"Doctor, you are too rigid."
Dr. Lena quickly asked: "Robin Hood, what can you do?"
"Why don't you apply for Abd's citizenship?" Robin Hood reminded with a wink.
"What?"
"You should be able to do it."
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 they agreed to help run the operation so that Abd could quickly become a naturalized citizen. After attending the African Climate Forum, he could directly apply to restore his citizenship.
Three days later, Dr. Lena, Robin Hood and others flew to Cairo to attend the African Climate Forum.
