Suyinshi area.

Cairo City.

Dr. Lena, who had just come off the plane, felt very cool, not at all like a subtropical desert climate zone, but like a subtropical monsoon climate.

Walking out of the airport, she stood next to the bus stop.

As far as the eye can see, the airport is surrounded by lush grasslands instead of endless deserts and the Gobi Desert.

Dr. Lena, who has been to Cairo Airport several times, was shocked by the change: "The climate change here is too great. ”

Another Western Roman scholar, who also came on a temporary basis, was equally surprised: "Isn't this the Nile agricultural area?" Aren't they afraid of the sea water pouring into the Nile? ”

A scholar from the Sand Kingdom with a telescope can see something through the types of herbs around:

"It shouldn't be seawater, none of these herbs are particularly salt-alkali tolerant types, and if Homo sapiens uses genetically modified technology, then I don't know."

Dr. Lena asked with concern, "Professor Yin Ben, has the climate of the Sand Kingdom also changed?" ”

"Well, there are some changes, especially along the Red Sea coast in the west, the air humidity has increased a lot, and this year's rainfall has increased by about 20% compared to the same period in previous years." Professor Yin Ben was not too worried.

Because the greening of the Sahara Desert and the increase in evaporation are good things for the sandy kingdom that is already a desert area.

After all, their territory is full of deserts, and agricultural development is very troublesome.

If it weren't for the fear of Homo sapiens' ability to do things, the Sand Kingdom would have introduced seawater crops a long time ago, and they are too greedy for seawater crops.

The desert area within the Sand Kingdom is vast, and if seawater crops can be introduced, then food and agricultural products can be completely self-sufficient, and even exported.

However, due to the fear of Homo sapiens doing things, the Sand Kingdom has never made up its mind.

Foreign scholars at the bus stop are still discussing.

A double-decker bus arrived at the station.

"The car has arrived." Robin Hood reminded.

A group of people lined up to get on the bus.

Dr. Lena and Robin Hood went up to the second floor and sat down casually.

The bus starts slowly.

Along the way are grasslands, and occasionally you can see some artificial lakes and small rivers.

At this time, the permanent population of Cairo City was not large, only about 3.74 million, and the previous tens of millions of people were arranged to other places by Su Yinshi Branch through recruitment and job transfer.

As a result, Cairo City is no longer as crowded as it used to be, and the climate has changed to make it more livable.

After passing through a forest park with an area of 5 square kilometers, the bus enters the city.

Towering broadcast towers, sky-high light rail and overpasses that dot the city.

Overall, the first impression of this brand new Cairo city to Dr. Lena is that it is spacious, clean and atmospheric.

After a while, the voice broadcast system of the bus issued a prompt:

[Dear passengers, we have arrived at Waterfall Square Station...... ］

When Dr. Lena, Robin Hood and others got out of the car, they saw a fountain waterfall with a height of 150 meters, and an artificial lake with a radius of 200 meters in the middle of the square.

The water vapor brought by the fountains and waterfalls makes the whole square very cool and moist.

Robin Hood flipped through the attached bio of the invitation, which showed the location of the forum, the Sun Palace.

The Sun Palace is not an office space, but a hotel similar to the Galaxy Hotel, which is also the usual style of Homo sapiens, that is, the practicality and commerciality of large buildings should be grasped.

The company did not have the idea of building a large palace to furnish it, which was usually a hotel, a restaurant, and could rent out a hall for temporary use for meetings and celebrations.

However, the headquarters of Homo sapiens branches in various regions often do not build large buildings, but small and refined buildings.

For example, the headquarters of Su Yinshi Branch is a very low-key Water Lily Palace, with an area of less than one-third of the Sun Palace and a height of only 20 meters.

The Sun Palace in front of you covers an area of 150,000 square meters and has a height of 333 meters.

Dr. Lena and the others showed the invitation to the waiter at the door, and they were taken to the Rich Hall on the 24th floor.

There were already quite a few people in the hall, and Dr. Lena soon saw a lot of her peers, and she hurried over to the two scholars with whom she had a better relationship.

"Heath, Brian, long time no see."

The middle-aged white man with gold-rimmed glasses looked surprised when he saw Dr. Lena: "Lena, how did you get a visa?" ”

"I am now a citizen of Abd." Lena spread her hands.

"I see! Haha......" The other fat black man laughed and shook his head.

Dr. Lena put away her joking and playful expression, and a trace of worry appeared on her face: "Brian, what's the climate like over there in the Transvaal?" Is there anything out of the ordinary? ”

The fat black man who took a sip of espresso shook his head: "I haven't found it for the time being, maybe it hasn't spread to southern Africa!" ”

Hiss made some discoveries: "In the past six months, Moore has received a lot more rain than in previous years. ”

Dr. Lena looked solemn: "Two, there is no way to get the Homo sapiens company to stop transforming the Sahara Desert?" Or delay development? ”

"It's ......," Brian frowned.

Don't look at the black fat man looking stupid, in fact, he is very shrewd, and he obviously knows that Homo sapiens will not change the development schedule.

Hiss took off his glasses and wiped them while persuading: "Lena, don't be naïve, Homo sapiens will not listen to us, and the sudden change in the global climate will be more beneficial to them." ”

"But if it continues like this, I'm worried that it will lead to a problem with the North Atlantic warm outflow." Lena became more and more worried.

Hearing this, the black fat man Brian's eyes narrowed slightly, but he secretly ridiculed in his heart: "If there is a problem with the warm flow of the North Atlantic, you Europa must be the first to be unlucky, and Homo sapiens will not care about your life or death." ’

】

"North Atlantic Current?" Hiss was concerned about this, after all, the Republic of Moore was on the northwest coast of Africa.

The problem of warm outflow from the North Atlantic is not only a matter of the North Atlantic, because the global ocean currents are all connected, and almost all of them affect the whole body.

He thought for a while, then shook his head very helplessly: "Our individual power is too small, and it is too difficult to influence the decision-making of Homo sapiens. ”

What they don't know is that as Homo sapiens gradually reduces the use of fossil fuels and increases the proportion of nuclear power, global greenhouse gas emissions intensity has dropped significantly.

Homo sapiens has engaged in large-scale seaweed cultivation in the shallow waters of Southeast Asia and seawater crops in the Sahara Desert, while also suppressing deforestation and development in Southeast Asia and the Amazon rainforest.

This has increased the scale of carbon sequestration in the ecosystem.

Therefore, instead of global warming, we have to worry about whether there will be global cooling.

After all, from the perspective of geological time, we are just in the middle of the ice age, and it is only the rapid industrialization of human beings in the past two hundred years that has emitted a large amount of greenhouse gases, so that people think that we are not in the ice age.

If the warming and insulating effect of industrial greenhouse gases is excluded, the earth has actually been getting cold for thousands of years.

Humanity should be grateful for the greenhouse gases produced by industrialization, otherwise it will be colder and more difficult to produce food in the middle and high latitudes.

The actions of Homo sapiens have inadvertently opened Pandora's box.
